Colpocleisis: A simple, effective, and underutilized procedure
CASE 1: Problematic prolapse, but no incontinence
An 81-year-old multiparous woman, who has a history of recurrent stage-III pelvic organ prolapse (POP), reports worsening discomfort that makes it difficult for her to care for her ailing husband. She also has “trouble” with bladder emptying and constipation, but denies any loss of urine. She has not had vaginal intercourse in more than a decade because of her husband’s medical condition.
Aside from health issues—she suffers from obesity, coronary artery disease, hypertension, and diabetes—the patient is content with her marriage of 58 years.
Urodynamic testing fails to demonstrate detrusor overactivity, stress urinary incontinence, or intrinsic sphincteric deficiency. A cough stress test is repeated after reduction of her prolapse using a large cotton swab, and confirms the findings of the urodynamic tests.
Is reconstructive surgery appropriate for this patient?
Traditional reconstructive surgical procedures for treating POP fail in as many as 30% of patients, and new approaches—some involving grafts—are proposed every day, often without much data behind them.1
Regardless of the approach, reconstructive surgery is a lengthy procedure that subjects patients who are already medically compromised to significant risk, including bleeding, infection, and fluid shifts. Delayed return to normal activity may be especially costly among elderly women because of the risk of venous thromboembolism.
Because of the high failure rate, slow recovery, and risk of complications, reconstructive surgery may not be as appropriate as colpocleisis for the woman described above. Colpocleisis—suturing the inside walls of the vagina together—has an efficacy rate exceeding 90%.2 This relatively simple operation has been around for almost two centuries and has a good track record, but is often overlooked when counseling a patient about her options.
Any frail, elderly woman who has stage-III or -IV POP who does not desire to preserve coital ability is a candidate for colpocleisis (TABLE). Advantages include:
- a short operating time
- few complications
- amenability of local anesthesia
- short hospitalization
- speedy recovery
- high success rate
- low rate of regret.2-5
Because it precludes coital activity, however, colpocleisis may cause problems with self-image. It also may lead to de novo or worsening urinary incontinence and complicate or delay the diagnosis of cervical and endometrial pathology.
This article explores these issues through a case-based discussion of colpocleisis, including a detailed description of surgical technique.

Requirements for colpocleisis
Both of the following must be present

Plus at least one of the following
|
Colpocleisis, as noted, entails suturing the inside walls of the vagina together. It is controversial because of its impact on coital activity. With careful patient selection, however, colpocleisis is considered a valid option for frail and elderly women who have POP and do not desire or foresee the possibility of future vaginal intercourse. Such women may represent a surprising percentage of the elderly population. A community-based survey found that 78% of married women 70 to 79 years old are not sexually active,6 and a study from The Netherlands found a prevalence of symptomatic POP of 11.4% among white women 45 to 85 years old.7
The fundamental reason for choosing an obliterative procedure such as colpocleisis over total pelvic reconstruction is to treat the prolapse with the least invasive technique in the shortest time. Hysterectomy, which often adds 30 to 80 minutes to the procedure, should therefore be performed only in patients who have a suspicious finding upon initial evaluation. For the same reason, partial colpocleisis—performed using the LeFort technique with limited dissection—has become the most popular obliterative approach. We try to avoid a total colpocleisis procedure—also known as colpectomy—in which the entire vaginal epithelium is stripped, because it is feasible only when the uterus is already absent or scheduled to be removed concomitantly.
(Note: The term vaginectomy should be reserved for gynecologic oncology procedures performed to remove vaginal cancer. Vaginectomy entails full-thickness excision of the vaginal walls, including the fibromuscular layer, as opposed to excision of the epithelial layer only, as in colpocleisis. In this article, we present the LeFort method, a partial colpocleisis technique, because we believe it is more easily adapted by the general gynecologist.8)
CASE 1 RESOLVED
After detailed counseling, which includes family members, the patient opts to undergo colpocleisis. The procedure takes 45 minutes. She is discharged on postoperative Day 1, and reports substantially improved quality of life.
CASE 2: Recurrent prolapse and problems with a pessary
A 72-year-old multiparous, widowed woman experiences recurrent stage-III isolated apical prolapse. She has already undergone two reconstructive procedures, and was discouraged from undergoing a third because of her chronic obstructive lung disease. She tried to use a Gellhorn-type pessary, which required a doctor’s intervention to insert and remove. Frustrated by the many office visits involved in having the pessary checked, she now demands surgical therapy. Another gynecologist has offered to repair the prolapse using mesh, but the patient has concerns about the safety and efficacy of the procedure because it is a relatively new approach.
In addition to the recurrent prolapse, she loses urine with stress and urge. She often has a postvoid residual volume >100 cc; urodynamic assessment confirms mixed urinary incontinence. The patient does not foresee any change in her social status (unmarried, sexually inactive).
Is colpocleisis a reasonable option?
Although the pessary is a helpful conservative alternative for women who are either unable or unwilling to undergo complex surgical pelvic repair and is considered first-line treatment by a majority of urogynecologists, it sometimes becomes more difficult to maintain than the patient is willing to tolerate.9 When a woman cannot remove and reinsert the device herself, the pessary requires a lifelong commitment to doctor’s visits every 2 or 3 months. This commitment is especially problematic for patients who become unable to drive or who lack social support.
Maintenance of the pessary becomes more frustrating as the patient becomes more dependent. Many gynecologists have seen a patient who developed a serious complication such as vesicovaginal or rectovaginal fistula because of a neglected pessary.10
In Case 2, the patient appears to be a potential candidate for colpocleisis, given her age and single status. Although pelvic floor repair appears to be safe in older women, any perioperative complication in a patient 70 years of age or older doubles the risk of discharge to a care facility.11,12 Women who have already undergone several surgeries or who have advanced medical problems such as coronary artery disease or cancer should be counseled thoroughly about the safety and efficacy of colpocleisis.
As for self-image, colpocleisis eliminates prolapse and reduces the genital hiatus. If the patient understands that colpocleisis is obliterative for the vagina but may improve the external appearance of the genital area, she may be more accepting of the procedure. One recent prospective, multicenter study found that only 2% of women thought their body looked worse 1 year after colpocleisis; 60% thought their body looked better.5
When reviewing treatment options, inform the patient that the pessary is a palliative option, whereas surgical therapy aims to be definitive.
CASE 2 RESOLVED
After comprehensive counseling, the patient elects to undergo colpocleisis, along with placement of a midurethral sling. She is discharged 1 day after surgery, and reports substantially improved urinary function, including bladder emptying, and quality of life. She says she would recommend the procedure to any woman who has a similar condition.
CASE 3: Pessary-related complications, incontinence, and underlying medical conditions
A 92-year-old multiparous widow, whose stage-IV uterovaginal prolapse has been managed by a pessary, develops vaginal ulcers in both anterior and posterior walls. After removal of the pessary and 4 weeks of treatment with vaginal estrogen, a smaller pessary is inserted, but she again develops ulcers and bleeding.
The patient’s medical condition is complicated by hypertension and generalized arthritis. She has urodynamically confirmed mixed urinary incontinence. She lives with her daughter and does not want to be placed in a nursing home.
What treatment options should you offer to her?
Because of this patient’s advanced age, poor health, and pessary-related problems, she is an ideal candidate for colpocleisis, provided she consents to the procedure after thorough counseling about its benefits and limitations.
Preoperative concerns
A thorough history, physical examination, and normal Pap test are necessary. If a suspicious pelvic mass or uterine bleeding is present, transvaginal ultrasonography (US) is crucial. In-office endometrial sampling also is necessary in any woman who has unexplained vaginal bleeding. More invasive procedures such as dilatation and curettage and hysteroscopy are needed only when the biopsy is inadequate or endometrial thickness exceeds 4 mm on transvaginal US.13
All elderly women who have high-risk medical problems must be cleared for surgery, with the necessary cardiac and pulmonary workup completed before the procedure.
Because colpocleisis is an extraperitoneal procedure, we have adapted use of over-the-counter enema products on the day before surgery in lieu of mechanical bowel preparation, which may lead to dehydration in very elderly women.
Coordinated consultation between the surgeon and anesthesiologist is necessary to determine the type of anesthesia to be used. Sedation and local anesthesia can be adequate for extremely high-risk women.14,15 Antibiotic prophylaxis is conventional for all patients.
Surgical technique
The LeFort method involves denudation and approximation of the midportions of the anterior and posterior vaginal walls.8 This operation creates a longitudinal vaginal septum with bilateral channels on each side, which serve as conduits for any secretion or bleeding from the apical vagina (FIGURE 1A AND B). Aggressive perineorraphy is also needed to shorten the genital hiatus. The following description incorporates perineorraphy into the LeFort technique.
FIGURE 1 Principles of LeFort colpocleisis
The depiction here is not anatomically precise: The vagina is illustrated as a rectangular prism to clarify the relationship between tissues.
Patient positioning
Place the patient in the dorsal lithotomy position, using stirrups to support the entire leg up to the knee. Let the patient’s buttocks overhang the edge of the table by 1 to 2 inches. A slight Trendelenburg position is imperative, especially when operating on the anterior compartment of the vagina. The bladder should be only partially emptied because the leakage of urine from the bladder makes it easier to identify inadvertent cystotomy. Infiltration of local anesthetic solution to develop the surgical planes is acceptable.
Initiating the procedure
Remove a rectangular piece of vaginal epithelium from the anterior vaginal wall, beginning 2 to 3 cm distal to the vaginal apex (or cervix, if the uterus is present) and ending immediately proximal to the urethrovesical junction to leave space for midurethral sling placement. Remove a similarly sized piece of epithelium from the posterior vaginal wall. This posterior rectangle is an almost geometric projection of the anterior rectangle, but is somewhat longer (2 to 3 cm) (FIGURE 1).
When removing the vaginal epithelium, it may be helpful to use the skills developed for anterior and posterior colporraphy. Our operation begins with a 5- to 6-cm transverse incision at the anterior vaginal apex, which creates the proximal side of the anterior rectangle described above (FIGURE 2A).
As you develop the plane between the epithelium and fibromuscular layer, make a midline sagittal incision and extend it to the urethrovesical junction (FIGURE 2B). Dissect the epithelium off the fibromuscular layer approximately 3 cm bilaterally, then make a transverse incision at the urethrovesical junction. Finally, remove the anterior rectangle in two pieces by cutting along the lateral sides (FIGURE 2C AND D). Remove the posterior rectangle using the same technique, but also excise a triangular piece of skin from the posterior fourchette for the perineorraphy portion of the procedure (FIGURE 2E).
FIGURE 2 LeFort technique, step by step
Begin with a 5–6 cm transverse incision at the anterior vaginal apex.
Dissect the epithelium off the fibromuscular layer, with a midline sagittal incision extending to the urethrovesical junction.
After dissection is completed, make a transverse incision at the urethrovesical junction, and remove the anterior rectangle in two pieces by cutting along the lateral sides.
Denude the posterior rectangle using the same technique. In addition, excise a triangular piece of skin from the perineum.
The posterior rectangle is ready for removal.
Suturing
Suture the apical sides of the anterior and posterior rectangles together using a continuous running technique (FIGURE 2F). Then approximate the lateral sides bilaterally using continuous sutures.
To ensure adherence of the anterior and posterior rectangles, stitch the raw surfaces together in three rows (FIGURE 2G). Do not include the distal 2 cm of the posterior vagina because you will need to leave room for perineorraphy.
Using several sutures, reapproximate the torn perineal fibromuscular structures in the midline to perform perineorraphy (FIGURE 2H). Close the distal vagina, beginning at the midpoint of the anterior transverse side, which lies at the urethrovesical junction (FIGURE 2I). Continue this suture on the posterior vagina and then the perineal body, sagittally, creating a small invagination in the distal vagina (FIGURE 2J).
FIGURE 2 LeFort technique, step by step
Suture all but the distal sides of the rectangles between the anterior and posterior vaginal walls.
Also stitch together the raw surfaces in three rows in an imbricating fashion.
Perform perineorraphy.
Close the distal vagina, starting at the midpoint of the anterior transverse side. If indicated, place a midurethral sling.
Final appearance.
Sling procedure
We place a midurethral sling as part of most colpocleisis operations. It is best to do this after the colpocleisis but before the perineorraphy.
In our cases, cystoscopy with simultaneous intravenous indigo carmine injection is standard before perineorraphy, even when a sling procedure is not planned. This safeguard ensures ureteral patency, which can be compromised (although rarely) in these procedures. Cutting and replacement of one of the sutures that approximate the raw tissues typically resolve the problem.16
Special considerations
Here are additional key points about colpocleisis, based on our experience:
- If an ulcer lies within the area designated to be denuded, some debridement to freshen up the surface will suffice. An ulcer is not an indication to deviate from the standard procedure.
- A modification developed by Goodall and Power may allow coitus by removing only a triangular piece of epithelium from each wall, leaving more room for the channels.17
- We have been unable to find any report of uterine or cervical cancer after colpocleisis, despite a MEDLINE search of the literature in English. Even so, the lateral channels created by the LeFort procedure allow any bleeding to escape the vagina, and may therefore enable recognition of malignancy. When noninvasive imaging techniques such as US or magnetic resonance are inadequate, vaginoscopy and hysteroscopy may be accomplished via these channels.
- When colpocleisis is performed in a hysterectomized woman, no lateral channel is necessary. Therefore, it is appropriate to do total colpocleisis.18,19
- When a patient with POP has a rectovaginal or vesicovaginal fistula caused by a neglected pessary, the addition of LeFort colpocleisis to the fistula repair may provide an effective treatment for both problems.10
Surgical outcomes
Success rate
Evidence concerning colpocleisis comes from case series, some of which are more than 30 years old. Although the definition of success is not clear in some series, the reported success rate has always exceeded 90% over the past three decades.2,18-22 Moreover, some of these reports involve as many as 30 years of follow-up.
Perioperative complication
In a recent review of the literature, the procedure-related mortality rate was 0.025%.2 When the authors focused only on studies published since 1980, major complications due to the patient’s underlying cardiovascular and pulmonary condition were seen in 2% of cases. Major surgical complications such as pyelonephritis and bleeding requiring transfusion occurred in 4% of cases, and less severe complications occurred in 15%.
In a study that included women who underwent concomitant vaginal hysterectomy, hysterectomy prolonged the surgery by 52 minutes, with a 5% rate of laparotomy as a result of intraoperative bleeding.22
In our series of 40 colpocleisis cases, we noted no instance in which a patient regretted the procedure.18 Others have also reported a low rate of regret—the highest being 9%.3-5,19-21
Using validated questionnaires, FitzGerald and colleagues found significant improvement in mental and physical quality of life, as well as urinary, colorectal, and bulge-related pelvic floor symptoms, 1 year after colpocleisis.5
De novo or worsening urinary incontinence is one of the drawbacks of colpocleisis. However, the same risk is present in approximately 40% of women who undergo surgical reconstructive procedures for POP without a continence operation.23 Because preoperative urinary retention is common in women who have POP, the decision to add a potentially harmful continence procedure is complicated in colpocleisis candidates. A small case series reported that the success rate ranged from 90% to 94% in women who underwent a midurethral tension-free sling procedure for the treatment of urinary incontinence at the time of colpocleisis.5
Preoperative urodynamic studies to detect urethral intrinsic deficiency and detrusor dysfunction are prudent, and detailed counseling of the patient about urinary control is vital. We perform a midurethral sling procedure in most of our colpocleisis cases, and have had pleasing results.
CASE 3 RESOLVED
The patient decides to undergo partial colpocleisis using the LeFort procedure, along with placement of a midurethral sling, for a total operative time of 75 minutes. She is discharged 1 day later and reports substantial improvement in urinary function and quality of life.

As you develop the plane between the epithelium and fibromuscular layer, make a midline sagittal incision and extend it to the urethrovesical junction (FIGURE 2B). Dissect the epithelium off the fibromuscular layer approximately 3 cm bilaterally, then make a transverse incision at the urethrovesical junction. Finally, remove the anterior rectangle in two pieces by cutting along the lateral sides (FIGURE 2C AND D). Remove the posterior rectangle using the same technique, but also excise a triangular piece of skin from the posterior fourchette for the perineorraphy portion of the procedure (FIGURE 2E).

Suturing
Suture the apical sides of the anterior and posterior rectangles together using a continuous running technique (FIGURE 2F). Then approximate the lateral sides bilaterally using continuous sutures.
To ensure adherence of the anterior and posterior rectangles, stitch the raw surfaces together in three rows (FIGURE 2G). Do not include the distal 2 cm of the posterior vagina because you will need to leave room for perineorraphy.
Using several sutures, reapproximate the torn perineal fibromuscular structures in the midline to perform perineorraphy (FIGURE 2H). Close the distal vagina, beginning at the midpoint of the anterior transverse side, which lies at the urethrovesical junction (FIGURE 2I). Continue this suture on the posterior vagina and then the perineal body, sagittally, creating a small invagination in the distal vagina (FIGURE 2J).

Sling procedure
We place a midurethral sling as part of most colpocleisis operations. It is best to do this after the colpocleisis but before the perineorraphy.
In our cases, cystoscopy with simultaneous intravenous indigo carmine injection is standard before perineorraphy, even when a sling procedure is not planned. This safeguard ensures ureteral patency, which can be compromised (although rarely) in these procedures. Cutting and replacement of one of the sutures that approximate the raw tissues typically resolve the problem.16
Special considerations
Here are additional key points about colpocleisis, based on our experience:
- If an ulcer lies within the area designated to be denuded, some debridement to freshen up the surface will suffice. An ulcer is not an indication to deviate from the standard procedure.
- A modification developed by Goodall and Power may allow coitus by removing only a triangular piece of epithelium from each wall, leaving more room for the channels.17
- We have been unable to find any report of uterine or cervical cancer after colpocleisis, despite a MEDLINE search of the literature in English. Even so, the lateral channels created by the LeFort procedure allow any bleeding to escape the vagina, and may therefore enable recognition of malignancy. When noninvasive imaging techniques such as US or magnetic resonance are inadequate, vaginoscopy and hysteroscopy may be accomplished via these channels.
- When colpocleisis is performed in a hysterectomized woman, no lateral channel is necessary. Therefore, it is appropriate to do total colpocleisis.18,19
- When a patient with POP has a rectovaginal or vesicovaginal fistula caused by a neglected pessary, the addition of LeFort colpocleisis to the fistula repair may provide an effective treatment for both problems.10
Surgical outcomes
Success rate
Evidence concerning colpocleisis comes from case series, some of which are more than 30 years old. Although the definition of success is not clear in some series, the reported success rate has always exceeded 90% over the past three decades.2,18-22 Moreover, some of these reports involve as many as 30 years of follow-up.
Perioperative complication
In a recent review of the literature, the procedure-related mortality rate was 0.025%.2 When the authors focused only on studies published since 1980, major complications due to the patient’s underlying cardiovascular and pulmonary condition were seen in 2% of cases. Major surgical complications such as pyelonephritis and bleeding requiring transfusion occurred in 4% of cases, and less severe complications occurred in 15%.
In a study that included women who underwent concomitant vaginal hysterectomy, hysterectomy prolonged the surgery by 52 minutes, with a 5% rate of laparotomy as a result of intraoperative bleeding.22
In our series of 40 colpocleisis cases, we noted no instance in which a patient regretted the procedure.18 Others have also reported a low rate of regret—the highest being 9%.3-5,19-21
Using validated questionnaires, FitzGerald and colleagues found significant improvement in mental and physical quality of life, as well as urinary, colorectal, and bulge-related pelvic floor symptoms, 1 year after colpocleisis.5
De novo or worsening urinary incontinence is one of the drawbacks of colpocleisis. However, the same risk is present in approximately 40% of women who undergo surgical reconstructive procedures for POP without a continence operation.23 Because preoperative urinary retention is common in women who have POP, the decision to add a potentially harmful continence procedure is complicated in colpocleisis candidates. A small case series reported that the success rate ranged from 90% to 94% in women who underwent a midurethral tension-free sling procedure for the treatment of urinary incontinence at the time of colpocleisis.5
Preoperative urodynamic studies to detect urethral intrinsic deficiency and detrusor dysfunction are prudent, and detailed counseling of the patient about urinary control is vital. We perform a midurethral sling procedure in most of our colpocleisis cases, and have had pleasing results.
CASE 3 RESOLVED
The patient decides to undergo partial colpocleisis using the LeFort procedure, along with placement of a midurethral sling, for a total operative time of 75 minutes. She is discharged 1 day later and reports substantial improvement in urinary function and quality of life.
CASE 1: Problematic prolapse, but no incontinence
An 81-year-old multiparous woman, who has a history of recurrent stage-III pelvic organ prolapse (POP), reports worsening discomfort that makes it difficult for her to care for her ailing husband. She also has “trouble” with bladder emptying and constipation, but denies any loss of urine. She has not had vaginal intercourse in more than a decade because of her husband’s medical condition.
Aside from health issues—she suffers from obesity, coronary artery disease, hypertension, and diabetes—the patient is content with her marriage of 58 years.
Urodynamic testing fails to demonstrate detrusor overactivity, stress urinary incontinence, or intrinsic sphincteric deficiency. A cough stress test is repeated after reduction of her prolapse using a large cotton swab, and confirms the findings of the urodynamic tests.
Is reconstructive surgery appropriate for this patient?
Traditional reconstructive surgical procedures for treating POP fail in as many as 30% of patients, and new approaches—some involving grafts—are proposed every day, often without much data behind them.1
Regardless of the approach, reconstructive surgery is a lengthy procedure that subjects patients who are already medically compromised to significant risk, including bleeding, infection, and fluid shifts. Delayed return to normal activity may be especially costly among elderly women because of the risk of venous thromboembolism.
Because of the high failure rate, slow recovery, and risk of complications, reconstructive surgery may not be as appropriate as colpocleisis for the woman described above. Colpocleisis—suturing the inside walls of the vagina together—has an efficacy rate exceeding 90%.2 This relatively simple operation has been around for almost two centuries and has a good track record, but is often overlooked when counseling a patient about her options.
Any frail, elderly woman who has stage-III or -IV POP who does not desire to preserve coital ability is a candidate for colpocleisis (TABLE). Advantages include:
- a short operating time
- few complications
- amenability of local anesthesia
- short hospitalization
- speedy recovery
- high success rate
- low rate of regret.2-5
Because it precludes coital activity, however, colpocleisis may cause problems with self-image. It also may lead to de novo or worsening urinary incontinence and complicate or delay the diagnosis of cervical and endometrial pathology.
This article explores these issues through a case-based discussion of colpocleisis, including a detailed description of surgical technique.
TABLE
Requirements for colpocleisis
Both of the following must be present
|
Plus at least one of the following
|
Colpocleisis, as noted, entails suturing the inside walls of the vagina together. It is controversial because of its impact on coital activity. With careful patient selection, however, colpocleisis is considered a valid option for frail and elderly women who have POP and do not desire or foresee the possibility of future vaginal intercourse. Such women may represent a surprising percentage of the elderly population. A community-based survey found that 78% of married women 70 to 79 years old are not sexually active,6 and a study from The Netherlands found a prevalence of symptomatic POP of 11.4% among white women 45 to 85 years old.7
The fundamental reason for choosing an obliterative procedure such as colpocleisis over total pelvic reconstruction is to treat the prolapse with the least invasive technique in the shortest time. Hysterectomy, which often adds 30 to 80 minutes to the procedure, should therefore be performed only in patients who have a suspicious finding upon initial evaluation. For the same reason, partial colpocleisis—performed using the LeFort technique with limited dissection—has become the most popular obliterative approach. We try to avoid a total colpocleisis procedure—also known as colpectomy—in which the entire vaginal epithelium is stripped, because it is feasible only when the uterus is already absent or scheduled to be removed concomitantly.
(Note: The term vaginectomy should be reserved for gynecologic oncology procedures performed to remove vaginal cancer. Vaginectomy entails full-thickness excision of the vaginal walls, including the fibromuscular layer, as opposed to excision of the epithelial layer only, as in colpocleisis. In this article, we present the LeFort method, a partial colpocleisis technique, because we believe it is more easily adapted by the general gynecologist.8)
CASE 1 RESOLVED
After detailed counseling, which includes family members, the patient opts to undergo colpocleisis. The procedure takes 45 minutes. She is discharged on postoperative Day 1, and reports substantially improved quality of life.
CASE 2: Recurrent prolapse and problems with a pessary
A 72-year-old multiparous, widowed woman experiences recurrent stage-III isolated apical prolapse. She has already undergone two reconstructive procedures, and was discouraged from undergoing a third because of her chronic obstructive lung disease. She tried to use a Gellhorn-type pessary, which required a doctor’s intervention to insert and remove. Frustrated by the many office visits involved in having the pessary checked, she now demands surgical therapy. Another gynecologist has offered to repair the prolapse using mesh, but the patient has concerns about the safety and efficacy of the procedure because it is a relatively new approach.
In addition to the recurrent prolapse, she loses urine with stress and urge. She often has a postvoid residual volume >100 cc; urodynamic assessment confirms mixed urinary incontinence. The patient does not foresee any change in her social status (unmarried, sexually inactive).
Is colpocleisis a reasonable option?
Although the pessary is a helpful conservative alternative for women who are either unable or unwilling to undergo complex surgical pelvic repair and is considered first-line treatment by a majority of urogynecologists, it sometimes becomes more difficult to maintain than the patient is willing to tolerate.9 When a woman cannot remove and reinsert the device herself, the pessary requires a lifelong commitment to doctor’s visits every 2 or 3 months. This commitment is especially problematic for patients who become unable to drive or who lack social support.
Maintenance of the pessary becomes more frustrating as the patient becomes more dependent. Many gynecologists have seen a patient who developed a serious complication such as vesicovaginal or rectovaginal fistula because of a neglected pessary.10
In Case 2, the patient appears to be a potential candidate for colpocleisis, given her age and single status. Although pelvic floor repair appears to be safe in older women, any perioperative complication in a patient 70 years of age or older doubles the risk of discharge to a care facility.11,12 Women who have already undergone several surgeries or who have advanced medical problems such as coronary artery disease or cancer should be counseled thoroughly about the safety and efficacy of colpocleisis.
As for self-image, colpocleisis eliminates prolapse and reduces the genital hiatus. If the patient understands that colpocleisis is obliterative for the vagina but may improve the external appearance of the genital area, she may be more accepting of the procedure. One recent prospective, multicenter study found that only 2% of women thought their body looked worse 1 year after colpocleisis; 60% thought their body looked better.5
When reviewing treatment options, inform the patient that the pessary is a palliative option, whereas surgical therapy aims to be definitive.
CASE 2 RESOLVED
After comprehensive counseling, the patient elects to undergo colpocleisis, along with placement of a midurethral sling. She is discharged 1 day after surgery, and reports substantially improved urinary function, including bladder emptying, and quality of life. She says she would recommend the procedure to any woman who has a similar condition.
CASE 3: Pessary-related complications, incontinence, and underlying medical conditions
A 92-year-old multiparous widow, whose stage-IV uterovaginal prolapse has been managed by a pessary, develops vaginal ulcers in both anterior and posterior walls. After removal of the pessary and 4 weeks of treatment with vaginal estrogen, a smaller pessary is inserted, but she again develops ulcers and bleeding.
The patient’s medical condition is complicated by hypertension and generalized arthritis. She has urodynamically confirmed mixed urinary incontinence. She lives with her daughter and does not want to be placed in a nursing home.
What treatment options should you offer to her?
Because of this patient’s advanced age, poor health, and pessary-related problems, she is an ideal candidate for colpocleisis, provided she consents to the procedure after thorough counseling about its benefits and limitations.
Preoperative concerns
A thorough history, physical examination, and normal Pap test are necessary. If a suspicious pelvic mass or uterine bleeding is present, transvaginal ultrasonography (US) is crucial. In-office endometrial sampling also is necessary in any woman who has unexplained vaginal bleeding. More invasive procedures such as dilatation and curettage and hysteroscopy are needed only when the biopsy is inadequate or endometrial thickness exceeds 4 mm on transvaginal US.13
All elderly women who have high-risk medical problems must be cleared for surgery, with the necessary cardiac and pulmonary workup completed before the procedure.
Because colpocleisis is an extraperitoneal procedure, we have adapted use of over-the-counter enema products on the day before surgery in lieu of mechanical bowel preparation, which may lead to dehydration in very elderly women.
Coordinated consultation between the surgeon and anesthesiologist is necessary to determine the type of anesthesia to be used. Sedation and local anesthesia can be adequate for extremely high-risk women.14,15 Antibiotic prophylaxis is conventional for all patients.
Surgical technique
The LeFort method involves denudation and approximation of the midportions of the anterior and posterior vaginal walls.8 This operation creates a longitudinal vaginal septum with bilateral channels on each side, which serve as conduits for any secretion or bleeding from the apical vagina (FIGURE 1A AND B). Aggressive perineorraphy is also needed to shorten the genital hiatus. The following description incorporates perineorraphy into the LeFort technique.
FIGURE 1 Principles of LeFort colpocleisis
The depiction here is not anatomically precise: The vagina is illustrated as a rectangular prism to clarify the relationship between tissues.
Patient positioning
Place the patient in the dorsal lithotomy position, using stirrups to support the entire leg up to the knee. Let the patient’s buttocks overhang the edge of the table by 1 to 2 inches. A slight Trendelenburg position is imperative, especially when operating on the anterior compartment of the vagina. The bladder should be only partially emptied because the leakage of urine from the bladder makes it easier to identify inadvertent cystotomy. Infiltration of local anesthetic solution to develop the surgical planes is acceptable.
Initiating the procedure
Remove a rectangular piece of vaginal epithelium from the anterior vaginal wall, beginning 2 to 3 cm distal to the vaginal apex (or cervix, if the uterus is present) and ending immediately proximal to the urethrovesical junction to leave space for midurethral sling placement. Remove a similarly sized piece of epithelium from the posterior vaginal wall. This posterior rectangle is an almost geometric projection of the anterior rectangle, but is somewhat longer (2 to 3 cm) (FIGURE 1).
When removing the vaginal epithelium, it may be helpful to use the skills developed for anterior and posterior colporraphy. Our operation begins with a 5- to 6-cm transverse incision at the anterior vaginal apex, which creates the proximal side of the anterior rectangle described above (FIGURE 2A).

Dissect the epithelium off the fibromuscular layer approximately 3 cm bilaterally, then make a transverse incision at the urethrovesical junction. Finally, remove the anterior rectangle in two pieces by cutting along the lateral sides (FIGURE 2C AND D). Remove the posterior rectangle using the same technique, but also excise a triangular piece of skin from the posterior fourchette for the perineorraphy portion of the procedure (FIGURE 2E).

CASE: History of dyspareunia
At her latest visit, a 56-year-old woman who is 7 years postmenopausal relates that she has been experiencing worsening pain with intercourse to the point that she now has very little sex drive at all. This problem began approximately 1 year after she discontinued hormone therapy in the wake of reports that it causes cancer and heart attack. She has been offered both local vaginal and systemic hormone therapy, but is too frightened to use any hormones at all. Sexual lubricants no longer seem to work.
How do you counsel her about these symptoms? And what therapy do you offer?
Physicians and other health-care practitioners are seeing a large and growing number of genitourinary and sexual-related complaints among menopausal women—so much so that it has reached epidemic proportions. Yet dyspareunia is underreported and undertreated, and quality of life suffers for these women.
In this article, I focus on two interrelated causes of this epidemic:
- vaginal dryness and vulvovaginal atrophy (VVA) and the impact of these conditions on women’s sexual function and psychosocial well-being
- barriers to optimal treatment.
I also explore how ObGyns’ role in this area of care is evolving—as a way to understand how you can better serve this expanding segment of our patient population.
Dyspareunia can have many causes, including endometriosis, interstitial cystitis, surgical scarring, injury that occurs during childbirth, and psychosocial origin (such as a history of sexual abuse). Our focus here is on dyspareunia due to VVA.
during sex. What should you do?
- Sexual pain as a category of female sexual dysfunction is relevant at any age; for postmenopausal women dealing with vaginal dryness as a result of estrogen deficiency, it may well be the dominant issue. When determining the cause of a sexual problem in a postmenopausal woman, put dyspareunia caused by vaginal dryness (as well as its psychosocial consequences) at the top of the list of possibilities.
- Bring up the topic of vaginal dryness and sexual pain with postmenopausal patients as part of the routine yearly exam, and explain the therapeutic capabilities of all available options.
- Estrogen therapy, either local or systemic, remains the standard when lubricants are inadequate. Make every effort to counsel the patient about the real risk:benefit ratio of estrogen use.
- If the patient is reluctant to use estrogen therapy, discuss with her the option of short-term local estrogen use, with the understanding that more acceptable options may become available in the near future. This may facilitate acceptance of short-term hormonal treatment and allow the patient to maintain her vaginal health and much of her vaginal sexual function.
- Keep abreast of both present and future options for therapy.
Just how sizable is the postmenopausal population?
About 32% of the female population is older than 50 years.1 That means that around 48 million women are currently menopausal, or will become so over the next few years.
Because average life expectancy approaches 80 years in the United States and other countries of the industrialized world,2 many women will live approximately 40 years beyond menopause or their final menstrual period. Their quality of life during the second half of their life is dependent on both physical and psychosocial health.
Postmenopausal dyspareunia isn’t new
Sexual issues arising from physical causes—dyspareunia among them—have long accounted for a large share of medical concerns reported by postmenopausal women. In a 1985 survey, for example, dyspareunia accounted for 42.5% of their complaints.3
But epidemiologic studies to determine the prevalence of female sexual dysfunction in postmenopausal women are difficult to carry out. Why? Because researchers would need to 1) address changes over time and 2) distinguish problems of sexual function from those brought on by aging.4
The techniques and methodology for researching female sexual dysfunction continue to evolve, creating new definitions of the stages of menopause and new diagnostic approaches to female sexual dysfunction.
However, based on available studies, Dennerstein and Hayes concluded that:
- postmenopausal women report a high rate of sexual dysfunction (higher than men)
- psychosocial factors can ameliorate a decline in sexual function
- “vaginal dryness and dyspareunia seem to be driven primarily by declining estradiol.”4
The WHI and its domino effect
Millions of postmenopausal women stopped taking estrogen-based therapy in the wake of widespread media coverage after 2002 publication of data from the estrogen–progestin arm of the Women’s Health Initiative (WHI), which purported to show, among other things, an increased risk of breast cancer.5
For decades, many postmenopausal women achieved medical management of VVA through long-term use of systemic hormone replacement therapy (HRT), which they used primarily to control other chronic symptoms of menopause, such as hot flashes.
After the WHI data were published (and misrepresented), reduced usage of estrogen-based HRT “unmasked” vaginal symptoms, including sexual pain, due to the effects of estrogen deficiency on the vaginal epithelium and vaginal blood flow. Since then, we have been forced to examine anew the natural history of menopause.
Within days or weeks of discontinuing HRT, women may reexperience the acute vasomotor symptoms that accompany estrogen withdrawal—most commonly hot flashes, night sweats, sleeplessness, palpitations, and headaches. Over time—anywhere from 6 months to several years—the body adjusts to the loss or withdrawal of estrogen, and these vasomotor symptoms eventually diminish or resolve. Not so for the longer-term physical effects of chronic low serum levels of estrogen, which worsen over time.
Approximately 6 months after discontinuing estrogen therapy, postmenopausal women may begin to experience vaginal dryness and VVA. As the years pass, other side effects of estrogen deficiency arise: bone loss, joint pain, mood alteration (including depression), change in skin tone, hair loss, and cardiac and central nervous system changes. These side effects do not resolve spontaneously; in fact, they grow worse as a woman ages. They may have deleterious psychosocial as well as physical impacts on her life—especially on the quality of her intimate relationship.
Clarify the report (adjust appropriately for same-sex partner)
- Where does it hurt? Describe the pain.
- When does it hurt? Does the pain occur 1) with penile contact at the opening of the vagina, 2) once the penis is partially in, 3) with full entry, 4) after some thrusting, 5) after deep thrusting, 6) with the partner’s ejaculation, 7) after withdrawal, or 8) with subsequent micturition?
- Does your body tense when your partner is attempting, or you are attempting, to insert his penis? What are your thoughts and feelings at this time?
- How long does the pain last?
- Does touching cause pain? Does it hurt when you ride a bicycle or wear tight clothes? Does penetration by tampons or fingers hurt?
Assess the pelvic floor
- Do you recognize the feeling of pelvic floor muscle tension during sexual contact?
- Do you recognize the feeling of pelvic floor muscle tension in other (nonsexual) situations?
Evaluate arousal
- Do you feel subjectively excited when you attempt intercourse?
- Does your vagina become sufficiently moist? Do you recognize the feeling of drying up?
Determine the consequences of the complaint
- What do you do when you experience pain during sexual contact? Do you continue? Or do you stop whatever is causing the pain?
- Do you continue to include intercourse or attempts at intercourse in your lovemaking, or do you use other methods of achieving sexual fulfillment? If you use other ways to make love, do you and your partner clearly understand that intercourse will not be attempted?
- What other effect does the pain have on your sexual relationship?
Explore biomedical antecedents
- When and how did the pain start?
- What tests have you undergone?
- What treatment have you received?

Is 60 the new 40?
Many women and men in the large cohort known as the Baby Boomer generation continue to be sexually active into their 60s, 70s, and 80s, as demonstrated by a 2007 study of sexuality and health in older adults.6 In the 57- to 64-year-old age group, 61.6% of women and 83.7% of men were sexually active (defined as sexual activity with a partner within the past 12 months). In the 65- to 74-year-old group, 39.5% of women and 67% of men were sexually active; and in the 75- to 85-year-old group, 16.7% of women and 38.5% of men were sexually active (TABLE).
These findings indicate that fewer women than men remain sexually active during their later years. One reason may be the epidemic of sexual-related symptoms among postmenopausal women. In the same survey, 34.3% of women 57 to 64 years old reported avoiding sex because of:
- pain during intercourse (17.8%)
- difficulty with lubrication (35.9%).
Across all groups, the most prevalent sexual problem was low desire (43%).6 Around 40% of postmenopausal women reported no sexual activity in the past 12 months, as well as lack of interest in sex. This number may include women who have ceased to have sex because of vaginal dryness and dyspareunia, thereby reducing the percentage reporting these symptoms (TABLE).

Assessing menopause-related sexual function is a challenge
Although the transition phases of menopause have been well studied and reported for decades, few of these studies have included questions about the impact of menopause on sexual function.7 When longitudinal studies that included the classification of female sexual dysfunction began to appear, they provided evidence of the important role that VVA and psychosocial factors play in female sexual dysfunction.8
In the fourth year of the Melbourne Women’s Midlife Health Project longitudinal study, six variables related to sexual function were identified. Three were determinate of sexual function:
- feelings for the partner
- problems related to the partner
- vaginal dryness/dyspareunia.
The other three variables—sexual responsiveness, frequency of sexual activity, and libido—were dependent or outcome variables.
By the sixth year of this study, two variables had increased in significance: vaginal dryness/dyspareunia and partner problems.7
Sexual pain and relationship problems can create a vicious cycle
The interrelationship of vaginal dryness, sexual pain, flagging desire, and psychosocial parameters can produce a vicious cycle. A woman experiencing or anticipating pain may have diminished sexual desire or avoid sex altogether. During intercourse, the brain’s awareness of vaginal pain may trigger a physiologic response that can cause the muscles of the vagina to tighten and lubrication to decrease. The result? Greater vaginal pain.
This vicious cycle can contribute to relationship issues with the sexual partner and harm a woman’s psychosocial well-being. Resentment, anger, and misunderstanding may arise when a couple is dealing with problems of sexual function, and these stressors can damage many aspects of the relationship, further exacerbating sexual difficulties.
An additional and very important dimension of these issues is their potential impact on the family unit.
VVA can diminish overall well-being
In a 2007 survey reported at the North American Menopause Society (NAMS), one third to one half of 506 respondents said that VVA had a bad effect on their sexual interest, mood, self-esteem, and the intimate relationship (FIGURE 1).9 Reports from in-depth interviews were consistent with survey results and offered further insight into a woman’s emotional response to the condition of vaginal dryness and its impact on her life. Women found the condition “embarrassing,” something they had to endure but didn’t talk about, and felt that it had a major impact on their self-esteem and intimate relationship.
FIGURE 1 Dyspareunia affects more than interest in sex—relationships, mood, and self-esteem suffer
Simon JA, Komi J. Vulvovaginal atrophy (VVA) negatively impacts sexual function, psychosocial well-being, and partner relationships. Poster presented at North American Menopause Association Annual Meeting; October 3-6, 2007; Dallas, Texas.
Clinicians often don’t ask about VVA, and patients are reluctant to talk
Among women of all ages, dyspareunia is underreported and undertreated. In the survey reported at NAMS, 40% of respondents said that their physician had never asked them about the problem of VVA (FIGURE 2).9
Women themselves may be reluctant to discuss the problem with physicians, nurse practitioners, or other health-care providers out of embarrassment or the assumption that there is nothing to be done about the problem. Nevertheless, more than 40% of respondents said they would be highly likely to seek treatment for VVA if they had a concern about urogenital complications of the condition (FIGURE 3).9
Another barrier may be the sense that asking the health-care provider about sex may embarrass him or her. As a result, sufferers do not anticipate help from their physician and other members of the health-care profession and fail to seek treatment or counseling for this chronic medical condition.10,11
In a 1999 telephone survey of 500 adults 25 years of age or older, 71% said they thought that their doctor would dismiss concerns about sexual problems, but 85% said they would talk to their physician anyway if they had a problem, even though they might not get treatment.11 In that survey, 91% of married men and 84% of married women rated a satisfying sex life as important to quality of life.11
Another important and often overlooked limitation on this type of discussion is the time constraints that busy clinicians face, especially with the low reimbursement offered by managed care. Sexual problems can hardly be adequately discussed in 7 to 10 minutes.

Women have performance anxiety, too
It is well known that men with even a mild degree of erectile dysfunction can suffer from performance anxiety, but the fact that women can also suffer from this phenomenon is not given as much attention. Such anxiety can be a factor in relationship difficulties. With both partners perhaps feeling anxious about sexual performance, a couple may avoid even simple acts of affection, such as holding hands, to avoid raising the other’s expectations.
Exacerbating the situation is the fact that many men use widely prescribed phosphodiesterase type 5 (PDE5) inhibitors, whereas women are contending with barriers to continued sexual activity as they age. It does not take a psychologist to understand that this imbalance often adds to emotional strain and tension between partners.
Popular media address the issue
Look beyond what our postmenopausal patients tell us directly—to the popular media and online forums—to appreciate the scope of sexual pain as a major issue among postmenopausal women. Evidence of psychosocial effects is found on numerous Web sites—some from organizations, others designed by women seeking help from each other.
Red Hot Mamas
This organization aims to empower women through menopause education. Highlighted in the Winter 2007/2008 Red Hot Mamas Report is a survey done in conjunction with Harris Interactive exploring the impact of menopausal symptoms on a woman’s sex life, which found that 47% of women who have VVA have avoided or stopped sex completely because it was uncomfortable, compared with 23% of normal women.
Power Surge
This Web site offers a list of strategies for dealing with sexual pain, including an overview of hormone-based prescription and nonprescription products, along with a variety of over-the-counter, natural, holistic, and herbal therapies for treating dyspareunia.
What is the physician’s role?
Given the epidemic of sexual pain, it is crucial that physicians and others who care for postmenopausal women increase their awareness of this issue and pay special attention to its psychosocial parameters.
Ask patients about sexual function in general and dyspareunia in particular as part of the routine annual visit. A simple opening “Yes/No” question, such as “Are you sexually active?” can lead to further questions appropriate to the patient. For example, if the answer is “No,” the follow-up question might be, “Does that bother you or your partner?” Further discussion may uncover whether the lack of sexual activity is a cause of distress and identify which variables are involved.
If, instead, the answer is “Yes,” follow-up questions can identify the presence of common postmenopausal physical issues, such as vaginal dryness and difficulty with lubrication. The visit then can turn to strategies to ameliorate those conditions.
When a patient reports dyspareunia, further diagnostic information such as precise location, degree of arousal, and reaction to pain can help determine the appropriate course of treatment. For an approach to this aspect of ascertaining patient history, see the list of sample questions above.12
During the physical, pay particular attention to any physical abnormalities or organic causes of sexual pain. Questions designed to characterize the location and nature of the pain can pinpoint the cause. Sexual pain arising from VVA is likely to 1) be localized at the introitus and 2) occur with penile entry.
Since the mid-1990s, the availability of validated scales to measure female sexual function has increased rapidly and enabled researchers to better identify, quantify, and evaluate treatments for female sexual dysfunction.7 Over time, we have moved away from the somewhat mechanical sequence inherent in the linear progression of desire leading to genital stimulation followed by arousal and orgasm toward an appreciation of the multiple physical, emotional, and subjective factors that are at play in women’s sexual function.
By 1998, a classification scheme was developed to further the means to study and discuss disorders of desire, arousal, orgasm, and sexual pain.8 Further contextual definitions of sexual dysfunction are under consideration.13
Basson proposed one new model of female sexual function (see the diagram), and observed that
"…women identify many reasons they are sexual over and beyond inherent sexual drive or “hunger.” Women tell of wanting to increase emotional closeness, commitment, sharing, tenderness, and tolerance, and to show the partner that he or she has been missed (emotionally or physically). Such intimacy-based reasons motivate the woman to find a way to become sexually aroused. This arousal is not spontaneous but triggered by deliberately sought sexual stimuli."13
Intimacy-based model of female sexual response cycle
In this flow of physical and emotional variables involved in female sexual function, categories interact. For example, low desire can be and is frequently secondary to the anticipation of pain during sexual intercourse. Arousal can be hampered by lack of vaginal lubrication—perhaps inhibited by the anticipation of pain. Secondary orgasmic disorders can result from low desire, difficulty of arousal, and sexual pain.14 Sexual pain can affect sexual function at any point on this continuum.
Treatments in the pipeline
For decades, hormone-based treatments have been the predominant therapeutic option for vaginal dryness. Often they are a secondary benefit of hormone therapy for vasomotor symptoms and osteoporosis. Estrogen can be delivered in the form of oral tablet, transdermal patch, gel, spray, or vaginal ring for systemic use, or as vaginal cream, ring, or tablet for local use.
However, despite data to the contrary and our reassurances to the patient about overall safety, a large number of women, and many primary care providers, are no longer inclined to use short- or long-term HRT in any presentation.
Other women may have risk factors that contraindicate exogenous hormones.
Nonhormonal options for vaginal dryness and dyspareunia are limited, and there are no approved systemic or oral nonestrogen options. Over-the-counter topical lubricants can ease some of the symptoms of VVA temporarily and allow successful vaginal penetration in many cases. Some may cause vaginal warming and pleasant sensations, but overall they treat the symptom rather than the source of pain. Moreover, many patients consider local lubricants messy and inconvenient and claim they “ruin the mood.”
The use of vaginal dilators along with estrogen or lubricant therapy is an often-forgotten adjunct to therapy for dyspareunia caused by VVA (FIGURE 4).
FIGURE 4 Mechanical dilation of the vagina is a useful adjunct
Mechanical dilation is often needed to restore penetration capability in the vagina, even after hormonal treatment. The focus should be on the vaginal introitus, with the top 25% to 35% of the dilator inserted into the opening once a day for 15 minutes, increasing the dilator diameter over time.
New SERMs are in development
Preclinical and clinical research into the diverse class of selective estrogen receptor modulators (SERMs) to treat estrogen-mediated disease produced tamoxifen for breast cancer prevention and raloxifene for both vertebral osteoporosis and breast cancer prevention. Each SERM seems to have unique tissue selectivity. The antiestrogenic activity of tamoxifen and raloxifene extends to the vagina and can exacerbate vaginal dryness.
A new generation of orally active SERMs is under investigation specifically for the treatment of chronic vaginal symptoms. These new agents target the nonvaginal treatment of VVA and associated symptoms. The first oral SERM for long-term treatment of these symptoms, ospemifene (Ophena), may become available in the near future. It is a novel SERM that has both anti-estrogenic and estrogenic actions, depending on the tissue. It was shown to significantly improve both vaginal dryness and dyspareunia in a large placebo-controlled trial.15

Millions of postmenopausal women stopped taking estrogen-based therapy in the wake of widespread media coverage after 2002 publication of data from the estrogen–progestin arm of the Women’s Health Initiative (WHI), which purported to show, among other things, an increased risk of breast cancer.5
For decades, many postmenopausal women achieved medical management of VVA through long-term use of systemic hormone replacement therapy (HRT), which they used primarily to control other chronic symptoms of menopause, such as hot flashes.
After the WHI data were published (and misrepresented), reduced usage of estrogen-based HRT “unmasked” vaginal symptoms, including sexual pain, due to the effects of estrogen deficiency on the vaginal epithelium and vaginal blood flow. Since then, we have been forced to examine anew the natural history of menopause.
Within days or weeks of discontinuing HRT, women may reexperience the acute vasomotor symptoms that accompany estrogen withdrawal—most commonly hot flashes, night sweats, sleeplessness, palpitations, and headaches. Over time—anywhere from 6 months to several years—the body adjusts to the loss or withdrawal of estrogen, and these vasomotor symptoms eventually diminish or resolve. Not so for the longer-term physical effects of chronic low serum levels of estrogen, which worsen over time.
Approximately 6 months after discontinuing estrogen therapy, postmenopausal women may begin to experience vaginal dryness and VVA. As the years pass, other side effects of estrogen deficiency arise: bone loss, joint pain, mood alteration (including depression), change in skin tone, hair loss, and cardiac and central nervous system changes. These side effects do not resolve spontaneously; in fact, they grow worse as a woman ages. They may have deleterious psychosocial as well as physical impacts on her life—especially on the quality of her intimate relationship.

Is 60 the new 40?
Many women and men in the large cohort known as the Baby Boomer generation continue to be sexually active into their 60s, 70s, and 80s, as demonstrated by a 2007 study of sexuality and health in older adults.6 In the 57- to 64-year-old age group, 61.6% of women and 83.7% of men were sexually active (defined as sexual activity with a partner within the past 12 months). In the 65- to 74-year-old group, 39.5% of women and 67% of men were sexually active; and in the 75- to 85-year-old group, 16.7% of women and 38.5% of men were sexually active (TABLE).
These findings indicate that fewer women than men remain sexually active during their later years. One reason may be the epidemic of sexual-related symptoms among postmenopausal women. In the same survey, 34.3% of women 57 to 64 years old reported avoiding sex because of:
- pain during intercourse (17.8%)
- difficulty with lubrication (35.9%).
Across all groups, the most prevalent sexual problem was low desire (43%).6 Around 40% of postmenopausal women reported no sexual activity in the past 12 months, as well as lack of interest in sex. This number may include women who have ceased to have sex because of vaginal dryness and dyspareunia, thereby reducing the percentage reporting these symptoms (TABLE).

Assessing menopause-related sexual function is a challenge
Although the transition phases of menopause have been well studied and reported for decades, few of these studies have included questions about the impact of menopause on sexual function.7 When longitudinal studies that included the classification of female sexual dysfunction began to appear, they provided evidence of the important role that VVA and psychosocial factors play in female sexual dysfunction.8
In the fourth year of the Melbourne Women’s Midlife Health Project longitudinal study, six variables related to sexual function were identified. Three were determinate of sexual function:
- feelings for the partner
- problems related to the partner
- vaginal dryness/dyspareunia.
The other three variables—sexual responsiveness, frequency of sexual activity, and libido—were dependent or outcome variables.
By the sixth year of this study, two variables had increased in significance: vaginal dryness/dyspareunia and partner problems.7
Sexual pain and relationship problems can create a vicious cycle
The interrelationship of vaginal dryness, sexual pain, flagging desire, and psychosocial parameters can produce a vicious cycle. A woman experiencing or anticipating pain may have diminished sexual desire or avoid sex altogether. During intercourse, the brain’s awareness of vaginal pain may trigger a physiologic response that can cause the muscles of the vagina to tighten and lubrication to decrease. The result? Greater vaginal pain.
This vicious cycle can contribute to relationship issues with the sexual partner and harm a woman’s psychosocial well-being. Resentment, anger, and misunderstanding may arise when a couple is dealing with problems of sexual function, and these stressors can damage many aspects of the relationship, further exacerbating sexual difficulties.
An additional and very important dimension of these issues is their potential impact on the family unit.
VVA can diminish overall well-being
In a 2007 survey reported at the North American Menopause Society (NAMS), one third to one half of 506 respondents said that VVA had a bad effect on their sexual interest, mood, self-esteem, and the intimate relationship (FIGURE 1).9 Reports from in-depth interviews were consistent with survey results and offered further insight into a woman’s emotional response to the condition of vaginal dryness and its impact on her life. Women found the condition “embarrassing,” something they had to endure but didn’t talk about, and felt that it had a major impact on their self-esteem and intimate relationship.
FIGURE 1 Dyspareunia affects more than interest in sex—relationships, mood, and self-esteem suffer
Simon JA, Komi J. Vulvovaginal atrophy (VVA) negatively impacts sexual function, psychosocial well-being, and partner relationships. Poster presented at North American Menopause Association Annual Meeting; October 3-6, 2007; Dallas, Texas.
Clinicians often don’t ask about VVA, and patients are reluctant to talk
Among women of all ages, dyspareunia is underreported and undertreated. In the survey reported at NAMS, 40% of respondents said that their physician had never asked them about the problem of VVA (FIGURE 2).9
Women themselves may be reluctant to discuss the problem with physicians, nurse practitioners, or other health-care providers out of embarrassment or the assumption that there is nothing to be done about the problem. Nevertheless, more than 40% of respondents said they would be highly likely to seek treatment for VVA if they had a concern about urogenital complications of the condition (FIGURE 3).9
Another barrier may be the sense that asking the health-care provider about sex may embarrass him or her. As a result, sufferers do not anticipate help from their physician and other members of the health-care profession and fail to seek treatment or counseling for this chronic medical condition.10,11
In a 1999 telephone survey of 500 adults 25 years of age or older, 71% said they thought that their doctor would dismiss concerns about sexual problems, but 85% said they would talk to their physician anyway if they had a problem, even though they might not get treatment.11 In that survey, 91% of married men and 84% of married women rated a satisfying sex life as important to quality of life.11
Another important and often overlooked limitation on this type of discussion is the time constraints that busy clinicians face, especially with the low reimbursement offered by managed care. Sexual problems can hardly be adequately discussed in 7 to 10 minutes.

Women have performance anxiety, too
It is well known that men with even a mild degree of erectile dysfunction can suffer from performance anxiety, but the fact that women can also suffer from this phenomenon is not given as much attention. Such anxiety can be a factor in relationship difficulties. With both partners perhaps feeling anxious about sexual performance, a couple may avoid even simple acts of affection, such as holding hands, to avoid raising the other’s expectations.
Exacerbating the situation is the fact that many men use widely prescribed phosphodiesterase type 5 (PDE5) inhibitors, whereas women are contending with barriers to continued sexual activity as they age. It does not take a psychologist to understand that this imbalance often adds to emotional strain and tension between partners.
Popular media address the issue
Look beyond what our postmenopausal patients tell us directly—to the popular media and online forums—to appreciate the scope of sexual pain as a major issue among postmenopausal women. Evidence of psychosocial effects is found on numerous Web sites—some from organizations, others designed by women seeking help from each other.
Red Hot Mamas
This organization aims to empower women through menopause education. Highlighted in the Winter 2007/2008 Red Hot Mamas Report is a survey done in conjunction with Harris Interactive exploring the impact of menopausal symptoms on a woman’s sex life, which found that 47% of women who have VVA have avoided or stopped sex completely because it was uncomfortable, compared with 23% of normal women.
Power Surge
This Web site offers a list of strategies for dealing with sexual pain, including an overview of hormone-based prescription and nonprescription products, along with a variety of over-the-counter, natural, holistic, and herbal therapies for treating dyspareunia.
What is the physician’s role?
Given the epidemic of sexual pain, it is crucial that physicians and others who care for postmenopausal women increase their awareness of this issue and pay special attention to its psychosocial parameters.
Ask patients about sexual function in general and dyspareunia in particular as part of the routine annual visit. A simple opening “Yes/No” question, such as “Are you sexually active?” can lead to further questions appropriate to the patient. For example, if the answer is “No,” the follow-up question might be, “Does that bother you or your partner?” Further discussion may uncover whether the lack of sexual activity is a cause of distress and identify which variables are involved.
If, instead, the answer is “Yes,” follow-up questions can identify the presence of common postmenopausal physical issues, such as vaginal dryness and difficulty with lubrication. The visit then can turn to strategies to ameliorate those conditions.
When a patient reports dyspareunia, further diagnostic information such as precise location, degree of arousal, and reaction to pain can help determine the appropriate course of treatment. For an approach to this aspect of ascertaining patient history, see the list of sample questions above.12
During the physical, pay particular attention to any physical abnormalities or organic causes of sexual pain. Questions designed to characterize the location and nature of the pain can pinpoint the cause. Sexual pain arising from VVA is likely to 1) be localized at the introitus and 2) occur with penile entry.
Since the mid-1990s, the availability of validated scales to measure female sexual function has increased rapidly and enabled researchers to better identify, quantify, and evaluate treatments for female sexual dysfunction.7 Over time, we have moved away from the somewhat mechanical sequence inherent in the linear progression of desire leading to genital stimulation followed by arousal and orgasm toward an appreciation of the multiple physical, emotional, and subjective factors that are at play in women’s sexual function.
By 1998, a classification scheme was developed to further the means to study and discuss disorders of desire, arousal, orgasm, and sexual pain.8 Further contextual definitions of sexual dysfunction are under consideration.13
Basson proposed one new model of female sexual function (see the diagram), and observed that
"…women identify many reasons they are sexual over and beyond inherent sexual drive or “hunger.” Women tell of wanting to increase emotional closeness, commitment, sharing, tenderness, and tolerance, and to show the partner that he or she has been missed (emotionally or physically). Such intimacy-based reasons motivate the woman to find a way to become sexually aroused. This arousal is not spontaneous but triggered by deliberately sought sexual stimuli."13
Intimacy-based model of female sexual response cycle
In this flow of physical and emotional variables involved in female sexual function, categories interact. For example, low desire can be and is frequently secondary to the anticipation of pain during sexual intercourse. Arousal can be hampered by lack of vaginal lubrication—perhaps inhibited by the anticipation of pain. Secondary orgasmic disorders can result from low desire, difficulty of arousal, and sexual pain.14 Sexual pain can affect sexual function at any point on this continuum.
Treatments in the pipeline
For decades, hormone-based treatments have been the predominant therapeutic option for vaginal dryness. Often they are a secondary benefit of hormone therapy for vasomotor symptoms and osteoporosis. Estrogen can be delivered in the form of oral tablet, transdermal patch, gel, spray, or vaginal ring for systemic use, or as vaginal cream, ring, or tablet for local use.
However, despite data to the contrary and our reassurances to the patient about overall safety, a large number of women, and many primary care providers, are no longer inclined to use short- or long-term HRT in any presentation.
Other women may have risk factors that contraindicate exogenous hormones.
Nonhormonal options for vaginal dryness and dyspareunia are limited, and there are no approved systemic or oral nonestrogen options. Over-the-counter topical lubricants can ease some of the symptoms of VVA temporarily and allow successful vaginal penetration in many cases. Some may cause vaginal warming and pleasant sensations, but overall they treat the symptom rather than the source of pain. Moreover, many patients consider local lubricants messy and inconvenient and claim they “ruin the mood.”
The use of vaginal dilators along with estrogen or lubricant therapy is an often-forgotten adjunct to therapy for dyspareunia caused by VVA (FIGURE 4).
FIGURE 4 Mechanical dilation of the vagina is a useful adjunct
Mechanical dilation is often needed to restore penetration capability in the vagina, even after hormonal treatment. The focus should be on the vaginal introitus, with the top 25% to 35% of the dilator inserted into the opening once a day for 15 minutes, increasing the dilator diameter over time.
New SERMs are in development
Preclinical and clinical research into the diverse class of selective estrogen receptor modulators (SERMs) to treat estrogen-mediated disease produced tamoxifen for breast cancer prevention and raloxifene for both vertebral osteoporosis and breast cancer prevention. Each SERM seems to have unique tissue selectivity. The antiestrogenic activity of tamoxifen and raloxifene extends to the vagina and can exacerbate vaginal dryness.
A new generation of orally active SERMs is under investigation specifically for the treatment of chronic vaginal symptoms. These new agents target the nonvaginal treatment of VVA and associated symptoms. The first oral SERM for long-term treatment of these symptoms, ospemifene (Ophena), may become available in the near future. It is a novel SERM that has both anti-estrogenic and estrogenic actions, depending on the tissue. It was shown to significantly improve both vaginal dryness and dyspareunia in a large placebo-controlled trial.15

CASE: History of dyspareunia
At her latest visit, a 56-year-old woman who is 7 years postmenopausal relates that she has been experiencing worsening pain with intercourse to the point that she now has very little sex drive at all. This problem began approximately 1 year after she discontinued hormone therapy in the wake of reports that it causes cancer and heart attack. She has been offered both local vaginal and systemic hormone therapy, but is too frightened to use any hormones at all. Sexual lubricants no longer seem to work.
How do you counsel her about these symptoms? And what therapy do you offer?
Physicians and other health-care practitioners are seeing a large and growing number of genitourinary and sexual-related complaints among menopausal women—so much so that it has reached epidemic proportions. Yet dyspareunia is underreported and undertreated, and quality of life suffers for these women.
In this article, I focus on two interrelated causes of this epidemic:
- vaginal dryness and vulvovaginal atrophy (VVA) and the impact of these conditions on women’s sexual function and psychosocial well-being
- barriers to optimal treatment.
I also explore how ObGyns’ role in this area of care is evolving—as a way to understand how you can better serve this expanding segment of our patient population.
Dyspareunia can have many causes, including endometriosis, interstitial cystitis, surgical scarring, injury that occurs during childbirth, and psychosocial origin (such as a history of sexual abuse). Our focus here is on dyspareunia due to VVA.
during sex. What should you do?
- Sexual pain as a category of female sexual dysfunction is relevant at any age; for postmenopausal women dealing with vaginal dryness as a result of estrogen deficiency, it may well be the dominant issue. When determining the cause of a sexual problem in a postmenopausal woman, put dyspareunia caused by vaginal dryness (as well as its psychosocial consequences) at the top of the list of possibilities.
- Bring up the topic of vaginal dryness and sexual pain with postmenopausal patients as part of the routine yearly exam, and explain the therapeutic capabilities of all available options.
- Estrogen therapy, either local or systemic, remains the standard when lubricants are inadequate. Make every effort to counsel the patient about the real risk:benefit ratio of estrogen use.
- If the patient is reluctant to use estrogen therapy, discuss with her the option of short-term local estrogen use, with the understanding that more acceptable options may become available in the near future. This may facilitate acceptance of short-term hormonal treatment and allow the patient to maintain her vaginal health and much of her vaginal sexual function.
- Keep abreast of both present and future options for therapy.
Just how sizable is the postmenopausal population?
About 32% of the female population is older than 50 years.1 That means that around 48 million women are currently menopausal, or will become so over the next few years.
Because average life expectancy approaches 80 years in the United States and other countries of the industrialized world,2 many women will live approximately 40 years beyond menopause or their final menstrual period. Their quality of life during the second half of their life is dependent on both physical and psychosocial health.
Postmenopausal dyspareunia isn’t new
Sexual issues arising from physical causes—dyspareunia among them—have long accounted for a large share of medical concerns reported by postmenopausal women. In a 1985 survey, for example, dyspareunia accounted for 42.5% of their complaints.3
But epidemiologic studies to determine the prevalence of female sexual dysfunction in postmenopausal women are difficult to carry out. Why? Because researchers would need to 1) address changes over time and 2) distinguish problems of sexual function from those brought on by aging.4
The techniques and methodology for researching female sexual dysfunction continue to evolve, creating new definitions of the stages of menopause and new diagnostic approaches to female sexual dysfunction.
However, based on available studies, Dennerstein and Hayes concluded that:
- postmenopausal women report a high rate of sexual dysfunction (higher than men)
- psychosocial factors can ameliorate a decline in sexual function
- “vaginal dryness and dyspareunia seem to be driven primarily by declining estradiol.”4
The WHI and its domino effect
Millions of postmenopausal women stopped taking estrogen-based therapy in the wake of widespread media coverage after 2002 publication of data from the estrogen–progestin arm of the Women’s Health Initiative (WHI), which purported to show, among other things, an increased risk of breast cancer.5

Since then, we have been forced to examine anew the natural history of menopause.
Within days or weeks of discontinuing HRT, women may reexperience the acute vasomotor symptoms that accompany estrogen withdrawal—most commonly hot flashes, night sweats, sleeplessness, palpitations, and headaches. Over time—anywhere from 6 months to several years—the body adjusts to the loss or withdrawal of estrogen, and these vasomotor symptoms eventually diminish or resolve. Not so for the longer-term physical effects of chronic low serum levels of estrogen, which worsen over time.
Approximately 6 months after discontinuing estrogen therapy, postmenopausal women may begin to experience vaginal dryness and VVA. As the years pass, other side effects of estrogen deficiency arise: bone loss, joint pain, mood alteration (including depression), change in skin tone, hair loss, and cardiac and central nervous system changes.

Nevertheless, more than 40% of respondents said they would be highly likely to seek treatment for VVA if they had a concern about urogenital complications of the condition (FIGURE 3).9
Another barrier may be the sense that asking the health-care provider about sex may embarrass him or her. As a result, sufferers do not anticipate help from their physician and other members of the health-care profession and fail to seek treatment or counseling for this chronic medical condition.10,11
In a 1999 telephone survey of 500 adults 25 years of age or older, 71% said they thought that their doctor would dismiss concerns about sexual problems, but 85% said they would talk to their physician anyway if they had a problem, even though they might not get treatment.11 In that survey, 91% of married men and 84% of married women rated a satisfying sex life as important to quality of life.11
Another important and often overlooked limitation on this type of discussion is the time constraints that busy clinicians face, especially with the low reimbursement offered by managed care. Sexual problems can hardly be adequately discussed in 7 to 10 minutes.

Women have performance anxiety, too
It is well known that men with even a mild degree of erectile dysfunction can suffer from performance anxiety, but the fact that women can also suffer from this phenomenon is not given as much attention. Such anxiety can be a factor in relationship difficulties. With both partners perhaps feeling anxious about sexual performance, a couple may avoid even simple acts of affection, such as holding hands, to avoid raising the other’s expectations.
Exacerbating the situation is the fact that many men use widely prescribed phosphodiesterase type 5 (PDE5) inhibitors, whereas women are contending with barriers to continued sexual activity as they age. It does not take a psychologist to understand that this imbalance often adds to emotional strain and tension between partners.
Popular media address the issue
Look beyond what our postmenopausal patients tell us directly—to the popular media and online forums—to appreciate the scope of sexual pain as a major issue among postmenopausal women. Evidence of psychosocial effects is found on numerous Web sites—some from organizations, others designed by women seeking help from each other.
Red Hot Mamas
This organization aims to empower women through menopause education. Highlighted in the Winter 2007/2008 Red Hot Mamas Report is a survey done in conjunction with Harris Interactive exploring the impact of menopausal symptoms on a woman’s sex life, which found that 47% of women who have VVA have avoided or stopped sex completely because it was uncomfortable, compared with 23% of normal women.
Power Surge
This Web site offers a list of strategies for dealing with sexual pain, including an overview of hormone-based prescription and nonprescription products, along with a variety of over-the-counter, natural, holistic, and herbal therapies for treating dyspareunia.
What is the physician’s role?
Given the epidemic of sexual pain, it is crucial that physicians and others who care for postmenopausal women increase their awareness of this issue and pay special attention to its psychosocial parameters.
Ask patients about sexual function in general and dyspareunia in particular as part of the routine annual visit. A simple opening “Yes/No” question, such as “Are you sexually active?” can lead to further questions appropriate to the patient. For example, if the answer is “No,” the follow-up question might be, “Does that bother you or your partner?” Further discussion may uncover whether the lack of sexual activity is a cause of distress and identify which variables are involved.
If, instead, the answer is “Yes,” follow-up questions can identify the presence of common postmenopausal physical issues, such as vaginal dryness and difficulty with lubrication. The visit then can turn to strategies to ameliorate those conditions.
When a patient reports dyspareunia, further diagnostic information such as precise location, degree of arousal, and reaction to pain can help determine the appropriate course of treatment. For an approach to this aspect of ascertaining patient history, see the list of sample questions above.12
During the physical, pay particular attention to any physical abnormalities or organic causes of sexual pain. Questions designed to characterize the location and nature of the pain can pinpoint the cause. Sexual pain arising from VVA is likely to 1) be localized at the introitus and 2) occur with penile entry.
Since the mid-1990s, the availability of validated scales to measure female sexual function has increased rapidly and enabled researchers to better identify, quantify, and evaluate treatments for female sexual dysfunction.7 Over time, we have moved away from the somewhat mechanical sequence inherent in the linear progression of desire leading to genital stimulation followed by arousal and orgasm toward an appreciation of the multiple physical, emotional, and subjective factors that are at play in women’s sexual function.
By 1998, a classification scheme was developed to further the means to study and discuss disorders of desire, arousal, orgasm, and sexual pain.8 Further contextual definitions of sexual dysfunction are under consideration.13
Basson proposed one new model of female sexual function (see the diagram), and observed that
"…women identify many reasons they are sexual over and beyond inherent sexual drive or “hunger.” Women tell of wanting to increase emotional closeness, commitment, sharing, tenderness, and tolerance, and to show the partner that he or she has been missed (emotionally or physically). Such intimacy-based reasons motivate the woman to find a way to become sexually aroused. This arousal is not spontaneous but triggered by deliberately sought sexual stimuli."13
Intimacy-based model of female sexual response cycle
In this flow of physical and emotional variables involved in female sexual function, categories interact. For example, low desire can be and is frequently secondary to the anticipation of pain during sexual intercourse. Arousal can be hampered by lack of vaginal lubrication—perhaps inhibited by the anticipation of pain. Secondary orgasmic disorders can result from low desire, difficulty of arousal, and sexual pain.14 Sexual pain can affect sexual function at any point on this continuum.
Treatments in the pipeline
For decades, hormone-based treatments have been the predominant therapeutic option for vaginal dryness. Often they are a secondary benefit of hormone therapy for vasomotor symptoms and osteoporosis. Estrogen can be delivered in the form of oral tablet, transdermal patch, gel, spray, or vaginal ring for systemic use, or as vaginal cream, ring, or tablet for local use.
However, despite data to the contrary and our reassurances to the patient about overall safety, a large number of women, and many primary care providers, are no longer inclined to use short- or long-term HRT in any presentation.
Other women may have risk factors that contraindicate exogenous hormones.
Nonhormonal options for vaginal dryness and dyspareunia are limited, and there are no approved systemic or oral nonestrogen options. Over-the-counter topical lubricants can ease some of the symptoms of VVA temporarily and allow successful vaginal penetration in many cases. Some may cause vaginal warming and pleasant sensations, but overall they treat the symptom rather than the source of pain. Moreover, many patients consider local lubricants messy and inconvenient and claim they “ruin the mood.”
The use of vaginal dilators along with estrogen or lubricant therapy is an often-forgotten adjunct to therapy for dyspareunia caused by VVA (FIGURE 4).
FIGURE 4 Mechanical dilation of the vagina is a useful adjunct
Mechanical dilation is often needed to restore penetration capability in the vagina, even after hormonal treatment. The focus should be on the vaginal introitus, with the top 25% to 35% of the dilator inserted into the opening once a day for 15 minutes, increasing the dilator diameter over time.
New SERMs are in development
Preclinical and clinical research into the diverse class of selective estrogen receptor modulators (SERMs) to treat estrogen-mediated disease produced tamoxifen for breast cancer prevention and raloxifene for both vertebral osteoporosis and breast cancer prevention. Each SERM seems to have unique tissue selectivity. The antiestrogenic activity of tamoxifen and raloxifene extends to the vagina and can exacerbate vaginal dryness.
A new generation of orally active SERMs is under investigation specifically for the treatment of chronic vaginal symptoms. These new agents target the nonvaginal treatment of VVA and associated symptoms. The first oral SERM for long-term treatment of these symptoms, ospemifene (Ophena), may become available in the near future. It is a novel SERM that has both anti-estrogenic and estrogenic actions, depending on the tissue. It was shown to significantly improve both vaginal dryness and dyspareunia in a large placebo-controlled trial.15

Expert tips for adnexal surgery through the laparoscope
The authors report no financial relationships relevant to this article.
CASE 1: Cystic mass in patient’s only remaining ovary
Mrs. R is a 29-year-old G1P1 who underwent a right oophorectomy, with a midline incision, for a dermoid cyst at the time of cesarean delivery. She now has a left ovarian cyst. Preoperative ultrasonography (US) reveals that it measures 3.5×4.2×3.7 cm and has both solid components and a multiloculated appearance, consistent with a dermoid cyst.
How common is this scenario?
Studies predict that one of every three women will undergo surgical management of an adnexal mass at some point in her life.1 This troubling statistic prompts several critical questions:
- How do we handle the workup for these women so that only appropriate patients undergo surgery?
- How often will a mass be malignant?
- How can we safely remove an adnexal mass to maximize patient safety, reduce overall recovery time, and prevent less favorable outcomes in women who are eventually found to have a malignancy?
A thorough workup and, sometimes, conservative management can prevent unnecessary surgery that may lead to early menopause or surgical complications. And maximizing the use of minimally invasive techniques in women who do require surgery can shorten hospital stay and recovery time. At the time of surgery, careful abdominal entry and meticulous surgical dissection and mass removal can limit the potential risks of laparoscopic excision in women who have an ultimate diagnosis of cancer.
In this article, we review the workup for women who have an adnexal mass, describe patient-selection criteria for laparoscopic surgery, including the risks and benefits of this approach ( TABLE 1 ), and present several techniques to safely manage a mass with potentially malignant histology via laparoscopy.
TABLE 1
There are benefits and risks to managing an adnexal mass laparoscopically
Benefit | Risk |
---|---|
Shorter recovery Fewer adhesions Decreased overall cost Magnification Decreased pain and narcotic use Fewer wound complications | Expensive equipment* Loss of tactile sensation Concern for malignancy Risk of tumor dissemination/spillage/chemical peritonitis Trocar-site metastasis |
*Though greater expense is not a risk per se, it does enter into decision making. |
Begin with the physical
When a woman is known to have a pelvic mass, the aim of the office exam is to 1) identify characteristics that suggest malignancy and 2) rule out nongynecologic causes of the mass. Physical findings that are worrisome for a malignant process include:
- fixed or nodular pelvic mass
- bilateral masses
- nodular abdominal mass
- ascites
- pleural effusion on auscultation or percussion of the lung.
Although these findings can be present under benign conditions, they increase the risk that a malignancy will be detected at surgery.
Other causes of a pelvic mass should also be considered, including infection (pelvic abscess) and tumors of the colon, particularly when the pelvic mass occurs on the left side.
Some symptoms, though vague, are worth noting
Although ovarian cancer was once thought to be a silent disease, recent research has shown that bloating, pelvic or abdominal pain, early satiety, and urinary frequency and urgency are more common among women with ovarian cancer than among healthy controls and patients in high-risk screening clinics.2-4 Although these symptoms are generally nonspecific, they merit attention if they occur more than 12 times a month and have been present for less than 1 year. When they meet these criteria, the symptoms have a sensitivity for diagnosing early- and late-stage ovarian cancer of 56.7% and 79.5%, respectively.4
Sensitivity for the diagnosis of early-stage ovarian cancer may be as high as 80% when the symptom index score is combined with an elevated level of the tumor marker CA 125.3
Transvaginal US is crucial
Transvaginal US is now standard practice to obtain high-resolution images of an adnexal mass. Grayscale US has traditionally been used alone for evaluation.
Specificity is typically lower in women who are premenopausal because many benign lesions, such as endometrioma, have a similar sonographic appearance to cancer.
A number of US scoring algorithms have now been proposed to aid in the triage of women who have an adnexal mass. Sensitivity of these algorithms ranges from 65% to 100%; specificity, from 77% to 95%.5
CA 125 is the standard tumor marker
For the past two decades, CA 125 has been the standard serum marker in the screening of high-risk women for ovarian cancer and the triage of women who have an adnexal mass.
This blood test has been studied widely since its introduction in 1983. It typically has sensitivity of 75% to 85% and specificity of 85% to 95% in identifying women who have ovarian cancer. However, it is elevated in only 50% to 60% of women who have stage I ovarian cancer. Its lack of specificity and poor positive predictive value have kept researchers busy trying to identify other serum markers, for both ovarian cancer and identification of high-risk pelvic masses.
Our recommended workup and management of adnexal masses In postmenopausal women who had a pelvic mass, one study found that a CA 125 level above 65 IU/mL had sensitivity of 71% and specificity of 92.5% in the identification of ovarian cancer.6 Another group found that CA 125 levels above 65 IU/mL were more than 95% sensitive in the diagnosis of ovarian cancer in postmenopausal women.7
Several studies have combined CA 125 with other markers or with US to screen high-risk women or triage those who have an adnexal mass. These studies have shown modest improvements in sensitivity but usually lower specificity than with CA 125 testing alone.
Markers that may be used for suspected sex cord stromas and germ-cell tumors are:
- lactate dehydrogenase (LDH) for dysgerminomas
- alpha-fetoprotein (AFP) and human chorionic gonadotropin (hCG) for yolk sac tumors
- testosterone for Sertoli-Leydig cell tumors
- inhibin A and B for granulosa cell tumors.
An algorithm for working up and managing adnexal masses appears above.
How to gain abdominal access
In the opening case, the patient clearly has a benign mass. The treatment? Safe entry into the peritoneal cavity to remove the cyst and as little normal tissue as possible. This is critical in this patient because she has only one ovary.
Peritoneal access for abdominal and pelvic laparoscopy has been studied widely. Options include:
- direct insertion using a Veress needle
- open laparoscopy
- direct trocar insertion.
The technique usually depends on the preference of the surgeon. The primary goal of abdominal entry is to minimize the risk of injury, particularly unrecognized injury.
Data on complication rates show no definite benefit for open versus closed techniques in the prevention of injury to underlying viscera. However, evidence does suggest that the open technique may lower the risk of major vascular injury.8
We employ direct trocar insertion using radially expanding or optical trocars.
The Veress needle option
When the Veress needle is used to gain intraperitoneal access, data indicate that initial intraperitoneal pressure below 10 mm Hg is a reliable marker for peritoneal entry, even in obese patients.9 Insufflation pressure as high as 25 to 30 mm Hg prior to placement of the initial trocar is safe from a cardiopulmonary standpoint and may allow easier entry with a nonbladed trocar.10
Tests to confirm intraperitoneal placement of the Veress needle, such as the hanging-drop test or saline flush, do not appear to offer any additional useful information.11
Open laparoscopy is suitable when adhesions are unlikely
Open laparoscopy is typically performed by making a minilaparotomy incision at the umbilicus and then dissecting and entering the peritoneal cavity. A blunt-tip trocar is inserted.
The disadvantage of this approach is that there may be extensive adhesions under the umbilicus, and it is difficult to dissect such adhesions sufficiently to introduce a cannula and laparoscope. Adhesions left behind often obscure the field of view after introduction of the trocar.
Our preference? Left upper-quadrant insertion
In Case 1, the previous midline incision mandates an alternative approach. When abdominal entry at the umbilicus is unsuccessful or potentially difficult because of an earlier midline incision, umbilical hernia repair, or history of multiple lower abdominal or pelvic surgeries, a left upper-quadrant insertion is useful. It is, in fact, our preferred technique, and involves a small incision at the midclavicular line 5 cm below the left costal margin, at a site called Palmer’s point.
The direction of insertion usually ranges from 45° to 90°, depending on the patient’s body weight. If the trocar is placed properly, the closest organs are the stomach and the left lobe of the liver (4 to 6 cm).12 Given the stomach’s close proximity, it should be decompressed with an orogastric tube prior to trocar insertion.
Several studies have demonstrated the safety and efficacy of this entry technique.12-14 It can be helpful in cases that involve difficult access. We usually use a 5-mm primary trocar site for a 5-mm laparoscope. Modern optics allow for a pristine view with these small scopes, eliminating the need to close fascia and perhaps causing less pain at the incision.
Accessory trocar sites facilitate complex technique
We usually use three accessory sites. Two of them are lower-quadrant ports that are placed 2 cm medial and 2 cm cephalad to the anterior superior iliac spine. This area generally lies well away from the inferior epigastric vessels and remains above the area of the ilioinguinal and iliohypogastric nerves, making it a safer point of insertion.15 One trocar is 5 mm in size and the other is 10 mm. The larger one is used to extract the specimen.
We place an additional 5-mm port lateral to the rectus muscle at the level of the umbilicus. This allows the principal surgeon to use two instruments (a toothed forceps and scissors) comfortably while the assistant holds the laparoscope and assists with a grasper.
Does the type of trocar matter?
No randomized studies have directly compared all types of trocars. Options include:
- a pyramidal tip (as in reusable trocars) or shielded tip
- radial expansion
- visible entry
- blunt (Hasson-type) trocar.
Safety data on direct comparison of trocars are limited, but it appears that a radially expanding trocar may offer less port-site pain and potentially less bleeding than a traditional cutting trocar.16 Moreover, the rate of hernia at the port site appears to be relatively low with a radially expanding trocar, even when fascia is left unclosed at a 10-mm site.17
None of these trocars appears to be clearly superior at avoiding visceral or vascular injury.
Technique of laparoscopic cyst removal
A video clip of the surgery is linked to this article in the Video Library at www.obgmanagement.com. In this case, a trocar was inserted in the left upper quadrant, and a laparoscopic cystectomy was initiated using the trocars already specified.
The peritoneal cavity and adnexa were inspected, followed by pelvic washings, as detailed in TABLE 2 . Next, the ovarian cortex was incised ( FIGURE 1A ) with scissors using bipolar or unipolar energy, typically at a low power setting, such as 12 to 15 watts.
It was relatively easy to develop a tissue plane between the cortex and underlying dermoid cyst using simple or aqua-dissection ( FIGURE 1B and C ). The cyst was enucleated without rupture and inserted into a specimen bag through a 10-mm port ( FIGURE 1D ). (The specimen bags generally are available in 10-mm and 15-mm sizes.) Once the trocar was removed, the entire specimen was brought out through the incision ( FIGURE 1E ).
Cystic masses can generally be carefully aspirated using a laparoscopic needle or angiocath, or they can be incised and drained using a standard suction device. Manufacturers of most specimen bags do not recommend the morcellation of tissue within the bag because of the potential for rupture of the bag with tumor spillage or injury to underlying structures.
Occasionally, the mass remains too large to remove after drainage of the cyst fluid. Remedies include enlarging the port site with a scalpel or using a gallbladder speculum to increase the diameter of the port site ( FIGURE 1E ). If possible, the incision should be large enough to deliver the entire bag intact. Use of excessive force will rupture the bag and may cause the specimen to be lost or malignant cells to be inadvertently spilled (in the case of a cancer diagnosis).

CASE 1: OUTCOME
The patient’s cyst is removed intact and she is discharged home. Rupture of a dermoid cyst is not associated with any problems as long as copious irrigation is used to aspirate the cyst content.18 Other cysts, such as endometriomas, may not be as easily dissected, and rupture is inevitable.
CASE 2: Symptoms suggestive of cancer
Mrs. B is a 47-year-old woman who reports abdominal bloating for the past 3 weeks. She also complains of early satiety and occasional constipation. She has no history of cancer, but her sister was given a diagnosis of breast cancer at 41 years of age, and her maternal aunt had breast cancer at 55 years.
Mrs. B is moderately obese, with a nontender abdomen and no palpable mass. Her pelvic exam also is negative for a mass or nodularity, but the extent of the exam is limited by body habitus. Her physician orders a transvaginal US, which reveals a 6-cm complex mass with thin septation and a 1-cm solid nodule, with no definite blood flow. The patient’s CA 125 level is 80 IU/mL, which we consider to be within the low-risk range for a premenopausal woman.
The patient is counseled about the need to have the mass removed and is scheduled for laparoscopic right salpingooophorectomy. Given the family history of breast cancer, the physician also requests consultation with a gynecologic oncologist, who agrees to assist with surgery and perform a laparotomy and staging in the event that a malignancy is diagnosed.
Is the mass likely to be malignant?
Given the patient’s family history of breast cancer, the recent onset of symptoms associated with ovarian cancer,2 and the characteristics of the mass (complex, with a nodule), malignancy is possible. This patient has an intermediate risk of cancer and requires additional counseling and planning.
However, most women who undergo laparoscopy for removal of an adnexal mass have benign pathologic findings.
What is the real risk of ovarian cancer?
The lifetime risk of developing ovarian cancer in the general population remains stable at approximately 1 in 70 women, with a mean age at diagnosis of 63 years.19 Ninety percent of ovarian cancer cases are sporadic, and less than 10% can be linked to genetic syndromes.
Women who have mutations in the BRCA1 gene carry a lifetime risk of ovarian cancer of up to 50%, and women who have mutations in BRCA2 have a lifetime risk of up to 25%.20,21 Women who have mutations associated with Lynch II syndrome or Hereditary Nonpolyposis Colorectal Cancer syndrome may have a lifetime risk of ovarian cancer of 12%.22,23
Some women who have a strong family history of breast and ovarian cancer do not carry a known mutation, but are likely to be at increased risk.
Additional risk factors known to be associated with ovarian cancer are nulliparity and infertility. However, the single most important risk factor for epithelial ovarian cancer is age.
Risk-reducing strategies include:
In the case of PBSO, it is imperative to ensure that all ovarian surface epithelium is removed. This means excising the infundibulopelvic ligament at least 1.5 cm above the proximal end of the ovary and excising any adjacent tissue to which the ovary is adherent (including pelvic sidewall peritoneum). Both requirements are easily achieved using the techniques outlined here.
Who should perform surgery?
The American College of Obstetricians and Gynecologists (ACOG) and the Society of Gynecologic Oncologists (SGO) have published guidelines for referral to a gynecologic oncologist ( TABLE 3 ). When Im and colleagues reviewed the records of more than 1,000 women who underwent surgery for a pelvic mass at six institutions over 12 months, they found that 70% of premenopausal women and 94% of postmenopausal women who were diagnosed with ovarian cancer were properly referred to a qualified subspecialist.27 “Over”-referral occurred in 30% to 40% of women who had a benign mass, but may be preferable given the importance of proper staging and debulking to survival.
ACOG and the SGO recommend referral for women who have:
- elevated tumor markers
- ascites
- a fixed or nodular mass
- a strong family history of breast or ovarian cancer.
Consider preoperative referral of all high-risk and, probably, intermediate-risk women, depending on the availability of qualified specialists for complete surgical staging.
In addition, women need to be counseled thoroughly about the possibility that a malignancy will be diagnosed by frozen section, necessitating additional surgical procedures.

Technique of laparoscopic adnexectomy
In Case 2, an umbilical site was chosen for the primary cannula. In general, the direction of insertion depends on the patient’s body habitus. Heavier patients have a thicker abdominal wall and an umbilicus below the level of the aortic bifurcation. In these women, the angle of insertion should be adjusted from the usual 45° (for patients of normal weight) to an angle nearer to 90°. Lateral ports are typical, as in Case 1.
Treat every mass like cancer
Laparoscopic excision of an adnexal mass can be safe and effective, with better outcomes and recovery than with laparotomy, provided the surgeon adheres to basic principles ( TABLE 2 ). This means treating every mass as though it is potentially malignant, and thoroughly inspecting the abdominal cavity before and after excision of the mass.
Know the retroperitoneal space
As with Case 1, successful laparoscopic excision of an adnexal mass begins with inspection of the peritoneal cavity, abdominopelvic washings, and identification of both the infundibulopelvic ligament and ureter. Knowledge of the retroperitoneal space can be of great value in difficult cases that involve significant pelvic adhesions or sidewall fibrosis. We generally use a retroperitoneal approach for laparoscopic adnexectomy ( FIGURE 2A ).
In our typical approach, we incise the peritoneum lateral to the uteroovarian ligament and continue the incision up the pelvic sidewall lateral to the infundibulopelvic ligament and up along the paracolic gutter, if needed ( FIGURE 2A ). We then mobilize the medial leaf of the broad ligament from the sidewall using blunt dissection between the external iliac vessels laterally and the ureter medially ( FIGURE 2B ).
Once we have identified the ureter, we use scissors to create a window in the medial leaf of the broad ligament just beneath the gonadal vessels. We then use an energy source to occlude and transect the pedicle. Using this technique, we secure the infundibulopelvic ligaments and safely mobilize the ureter before initiating more aggressive sidewall dissection distally for adhesions or fibrosis.
Once the ureter is mobilized, we excise the involved peritoneum along with the mass. We then seal and transect the uteroovarian ligament.
FIGURE 2 The retroperitoneal approach
Grasp and incise the peritoneum just lateral to the adnexal mass and enter the retroperitoneal space, where loose areolar tissue is visible, with the ureter seen on the medial leaf of the broad ligament.
After dissecting this tissue, identify the ureter and internal iliac vessels.
Remove the mass in a bag
Once the mass is excised, we place it in a laparoscopic bag, as described for Case 1. Solid adnexal masses are problematic because they are not amenable to drainage, and morcellation is usually discouraged. Laparoscopic excision can still be carried out, and a minilaparotomy or posterior colpotomy can be used to extract the mass in a bag. Patients managed in this way still have a complication rate similar to or lower than that of patients undergoing laparotomy for oophorectomy; they also recover faster.
Risks in cases of malignancy
The risk of tumor spillage in laparoscopic surgery can be lowered using laparoscopically guided minilaparotomy techniques. Preoperative rupture appears to be more predictive of outcome.28
The concern about metastatic implants in a laparoscopic port site in patients who have gynecologic cancer is real, with an incidence ranging from 0.97% to 1.1%. The phenomenon usually affects women who had ovarian cancer and is most common after laparoscopy with findings of ascites, carcinomatosis, or persistent disease (in the case of second-look laparoscopy performed after completion of primary therapy for ovarian cancer).
These data suggest that port-site implantation is not a concern that should deter clinicians from laparoscopic evaluation of a suspected ovarian neoplasm unless a patient presents with ascites or carcinomatosis suggestive of advanced disease.29
Data are limited regarding delays in definitive therapy. One study suggests that definitive staging on the day of rupture does not influence overall outcome, but delay by more than 2 weeks may lead to poorer prognosis.30
CASE 2: OUTCOME
Laparoscopy is performed. On initial inspection, the peritoneal cavity is unremarkable. The right ovary is multicystic with normal surface anatomy. The mass is somewhat adherent to the pelvic sidewall. Adnexectomy is performed, and frozen section reveals the mass to be a serous cystadenoma.

CASE 1: Cystic mass in patient’s only remaining ovary
Mrs. R is a 29-year-old G1P1 who underwent a right oophorectomy, with a midline incision, for a dermoid cyst at the time of cesarean delivery. She now has a left ovarian cyst. Preoperative ultrasonography (US) reveals that it measures 3.5×4.2×3.7 cm and has both solid components and a multiloculated appearance, consistent with a dermoid cyst.
How common is this scenario?
Studies predict that one of every three women will undergo surgical management of an adnexal mass at some point in her life.1 This troubling statistic prompts several critical questions:
- How do we handle the workup for these women so that only appropriate patients undergo surgery?
- How often will a mass be malignant?
- How can we safely remove an adnexal mass to maximize patient safety, reduce overall recovery time, and prevent less favorable outcomes in women who are eventually found to have a malignancy?
A thorough workup and, sometimes, conservative management can prevent unnecessary surgery that may lead to early menopause or surgical complications. And maximizing the use of minimally invasive techniques in women who do require surgery can shorten hospital stay and recovery time. At the time of surgery, careful abdominal entry and meticulous surgical dissection and mass removal can limit the potential risks of laparoscopic excision in women who have an ultimate diagnosis of cancer.
In this article, we review the workup for women who have an adnexal mass, describe patient-selection criteria for laparoscopic surgery, including the risks and benefits of this approach ( TABLE 1 ), and present several techniques to safely manage a mass with potentially malignant histology via laparoscopy.
TABLE 1
There are benefits and risks to managing an adnexal mass laparoscopically
Benefit | Risk |
---|---|
Shorter recovery Fewer adhesions Decreased overall cost Magnification Decreased pain and narcotic use Fewer wound complications | Expensive equipment* Loss of tactile sensation Concern for malignancy Risk of tumor dissemination/spillage/chemical peritonitis Trocar-site metastasis |
*Though greater expense is not a risk per se, it does enter into decision making. |
Begin with the physical
When a woman is known to have a pelvic mass, the aim of the office exam is to 1) identify characteristics that suggest malignancy and 2) rule out nongynecologic causes of the mass. Physical findings that are worrisome for a malignant process include:
- fixed or nodular pelvic mass
- bilateral masses
- nodular abdominal mass
- ascites
- pleural effusion on auscultation or percussion of the lung.
Although these findings can be present under benign conditions, they increase the risk that a malignancy will be detected at surgery.
Other causes of a pelvic mass should also be considered, including infection (pelvic abscess) and tumors of the colon, particularly when the pelvic mass occurs on the left side.
Some symptoms, though vague, are worth noting
Although ovarian cancer was once thought to be a silent disease, recent research has shown that bloating, pelvic or abdominal pain, early satiety, and urinary frequency and urgency are more common among women with ovarian cancer than among healthy controls and patients in high-risk screening clinics.2-4 Although these symptoms are generally nonspecific, they merit attention if they occur more than 12 times a month and have been present for less than 1 year. When they meet these criteria, the symptoms have a sensitivity for diagnosing early- and late-stage ovarian cancer of 56.7% and 79.5%, respectively.4
Sensitivity for the diagnosis of early-stage ovarian cancer may be as high as 80% when the symptom index score is combined with an elevated level of the tumor marker CA 125.3
Transvaginal US is crucial
Transvaginal US is now standard practice to obtain high-resolution images of an adnexal mass. Grayscale US has traditionally been used alone for evaluation.
Specificity is typically lower in women who are premenopausal because many benign lesions, such as endometrioma, have a similar sonographic appearance to cancer.
A number of US scoring algorithms have now been proposed to aid in the triage of women who have an adnexal mass. Sensitivity of these algorithms ranges from 65% to 100%; specificity, from 77% to 95%.5
CA 125 is the standard tumor marker
For the past two decades, CA 125 has been the standard serum marker in the screening of high-risk women for ovarian cancer and the triage of women who have an adnexal mass.
This blood test has been studied widely since its introduction in 1983. It typically has sensitivity of 75% to 85% and specificity of 85% to 95% in identifying women who have ovarian cancer. However, it is elevated in only 50% to 60% of women who have stage I ovarian cancer. Its lack of specificity and poor positive predictive value have kept researchers busy trying to identify other serum markers, for both ovarian cancer and identification of high-risk pelvic masses.
Our recommended workup and management of adnexal masses In postmenopausal women who had a pelvic mass, one study found that a CA 125 level above 65 IU/mL had sensitivity of 71% and specificity of 92.5% in the identification of ovarian cancer.6 Another group found that CA 125 levels above 65 IU/mL were more than 95% sensitive in the diagnosis of ovarian cancer in postmenopausal women.7
Several studies have combined CA 125 with other markers or with US to screen high-risk women or triage those who have an adnexal mass. These studies have shown modest improvements in sensitivity but usually lower specificity than with CA 125 testing alone.
Markers that may be used for suspected sex cord stromas and germ-cell tumors are:
- lactate dehydrogenase (LDH) for dysgerminomas
- alpha-fetoprotein (AFP) and human chorionic gonadotropin (hCG) for yolk sac tumors
- testosterone for Sertoli-Leydig cell tumors
- inhibin A and B for granulosa cell tumors.
An algorithm for working up and managing adnexal masses appears above.
How to gain abdominal access
In the opening case, the patient clearly has a benign mass. The treatment? Safe entry into the peritoneal cavity to remove the cyst and as little normal tissue as possible. This is critical in this patient because she has only one ovary.
Peritoneal access for abdominal and pelvic laparoscopy has been studied widely. Options include:
- direct insertion using a Veress needle
- open laparoscopy
- direct trocar insertion.
The technique usually depends on the preference of the surgeon. The primary goal of abdominal entry is to minimize the risk of injury, particularly unrecognized injury.
Data on complication rates show no definite benefit for open versus closed techniques in the prevention of injury to underlying viscera. However, evidence does suggest that the open technique may lower the risk of major vascular injury.8
We employ direct trocar insertion using radially expanding or optical trocars.
The Veress needle option
When the Veress needle is used to gain intraperitoneal access, data indicate that initial intraperitoneal pressure below 10 mm Hg is a reliable marker for peritoneal entry, even in obese patients.9 Insufflation pressure as high as 25 to 30 mm Hg prior to placement of the initial trocar is safe from a cardiopulmonary standpoint and may allow easier entry with a nonbladed trocar.10
Tests to confirm intraperitoneal placement of the Veress needle, such as the hanging-drop test or saline flush, do not appear to offer any additional useful information.11
Open laparoscopy is suitable when adhesions are unlikely
Open laparoscopy is typically performed by making a minilaparotomy incision at the umbilicus and then dissecting and entering the peritoneal cavity. A blunt-tip trocar is inserted.
The disadvantage of this approach is that there may be extensive adhesions under the umbilicus, and it is difficult to dissect such adhesions sufficiently to introduce a cannula and laparoscope. Adhesions left behind often obscure the field of view after introduction of the trocar.
Our preference? Left upper-quadrant insertion
In Case 1, the previous midline incision mandates an alternative approach. When abdominal entry at the umbilicus is unsuccessful or potentially difficult because of an earlier midline incision, umbilical hernia repair, or history of multiple lower abdominal or pelvic surgeries, a left upper-quadrant insertion is useful. It is, in fact, our preferred technique, and involves a small incision at the midclavicular line 5 cm below the left costal margin, at a site called Palmer’s point.
The direction of insertion usually ranges from 45° to 90°, depending on the patient’s body weight. If the trocar is placed properly, the closest organs are the stomach and the left lobe of the liver (4 to 6 cm).12 Given the stomach’s close proximity, it should be decompressed with an orogastric tube prior to trocar insertion.
Several studies have demonstrated the safety and efficacy of this entry technique.12-14 It can be helpful in cases that involve difficult access. We usually use a 5-mm primary trocar site for a 5-mm laparoscope. Modern optics allow for a pristine view with these small scopes, eliminating the need to close fascia and perhaps causing less pain at the incision.
Accessory trocar sites facilitate complex technique
We usually use three accessory sites. Two of them are lower-quadrant ports that are placed 2 cm medial and 2 cm cephalad to the anterior superior iliac spine. This area generally lies well away from the inferior epigastric vessels and remains above the area of the ilioinguinal and iliohypogastric nerves, making it a safer point of insertion.15 One trocar is 5 mm in size and the other is 10 mm. The larger one is used to extract the specimen.
We place an additional 5-mm port lateral to the rectus muscle at the level of the umbilicus. This allows the principal surgeon to use two instruments (a toothed forceps and scissors) comfortably while the assistant holds the laparoscope and assists with a grasper.
Does the type of trocar matter?
No randomized studies have directly compared all types of trocars. Options include:
- a pyramidal tip (as in reusable trocars) or shielded tip
- radial expansion
- visible entry
- blunt (Hasson-type) trocar.
Safety data on direct comparison of trocars are limited, but it appears that a radially expanding trocar may offer less port-site pain and potentially less bleeding than a traditional cutting trocar.16 Moreover, the rate of hernia at the port site appears to be relatively low with a radially expanding trocar, even when fascia is left unclosed at a 10-mm site.17
None of these trocars appears to be clearly superior at avoiding visceral or vascular injury.
Technique of laparoscopic cyst removal
A video clip of the surgery is linked to this article in the Video Library at www.obgmanagement.com. In this case, a trocar was inserted in the left upper quadrant, and a laparoscopic cystectomy was initiated using the trocars already specified.
The peritoneal cavity and adnexa were inspected, followed by pelvic washings, as detailed in TABLE 2 . Next, the ovarian cortex was incised ( FIGURE 1A ) with scissors using bipolar or unipolar energy, typically at a low power setting, such as 12 to 15 watts.
It was relatively easy to develop a tissue plane between the cortex and underlying dermoid cyst using simple or aqua-dissection ( FIGURE 1B and C ). The cyst was enucleated without rupture and inserted into a specimen bag through a 10-mm port ( FIGURE 1D ). (The specimen bags generally are available in 10-mm and 15-mm sizes.) Once the trocar was removed, the entire specimen was brought out through the incision ( FIGURE 1E ).
Cystic masses can generally be carefully aspirated using a laparoscopic needle or angiocath, or they can be incised and drained using a standard suction device. Manufacturers of most specimen bags do not recommend the morcellation of tissue within the bag because of the potential for rupture of the bag with tumor spillage or injury to underlying structures.
Occasionally, the mass remains too large to remove after drainage of the cyst fluid. Remedies include enlarging the port site with a scalpel or using a gallbladder speculum to increase the diameter of the port site ( FIGURE 1E ). If possible, the incision should be large enough to deliver the entire bag intact. Use of excessive force will rupture the bag and may cause the specimen to be lost or malignant cells to be inadvertently spilled (in the case of a cancer diagnosis).

CASE 1: OUTCOME
The patient’s cyst is removed intact and she is discharged home. Rupture of a dermoid cyst is not associated with any problems as long as copious irrigation is used to aspirate the cyst content.18 Other cysts, such as endometriomas, may not be as easily dissected, and rupture is inevitable.
CASE 2: Symptoms suggestive of cancer
Mrs. B is a 47-year-old woman who reports abdominal bloating for the past 3 weeks. She also complains of early satiety and occasional constipation. She has no history of cancer, but her sister was given a diagnosis of breast cancer at 41 years of age, and her maternal aunt had breast cancer at 55 years.
Mrs. B is moderately obese, with a nontender abdomen and no palpable mass. Her pelvic exam also is negative for a mass or nodularity, but the extent of the exam is limited by body habitus. Her physician orders a transvaginal US, which reveals a 6-cm complex mass with thin septation and a 1-cm solid nodule, with no definite blood flow. The patient’s CA 125 level is 80 IU/mL, which we consider to be within the low-risk range for a premenopausal woman.
The patient is counseled about the need to have the mass removed and is scheduled for laparoscopic right salpingooophorectomy. Given the family history of breast cancer, the physician also requests consultation with a gynecologic oncologist, who agrees to assist with surgery and perform a laparotomy and staging in the event that a malignancy is diagnosed.
Is the mass likely to be malignant?
Given the patient’s family history of breast cancer, the recent onset of symptoms associated with ovarian cancer,2 and the characteristics of the mass (complex, with a nodule), malignancy is possible. This patient has an intermediate risk of cancer and requires additional counseling and planning.
However, most women who undergo laparoscopy for removal of an adnexal mass have benign pathologic findings.
What is the real risk of ovarian cancer?
The lifetime risk of developing ovarian cancer in the general population remains stable at approximately 1 in 70 women, with a mean age at diagnosis of 63 years.19 Ninety percent of ovarian cancer cases are sporadic, and less than 10% can be linked to genetic syndromes.
Women who have mutations in the BRCA1 gene carry a lifetime risk of ovarian cancer of up to 50%, and women who have mutations in BRCA2 have a lifetime risk of up to 25%.20,21 Women who have mutations associated with Lynch II syndrome or Hereditary Nonpolyposis Colorectal Cancer syndrome may have a lifetime risk of ovarian cancer of 12%.22,23
Some women who have a strong family history of breast and ovarian cancer do not carry a known mutation, but are likely to be at increased risk.
Additional risk factors known to be associated with ovarian cancer are nulliparity and infertility. However, the single most important risk factor for epithelial ovarian cancer is age.
Risk-reducing strategies include:
In the case of PBSO, it is imperative to ensure that all ovarian surface epithelium is removed. This means excising the infundibulopelvic ligament at least 1.5 cm above the proximal end of the ovary and excising any adjacent tissue to which the ovary is adherent (including pelvic sidewall peritoneum). Both requirements are easily achieved using the techniques outlined here.
Who should perform surgery?
The American College of Obstetricians and Gynecologists (ACOG) and the Society of Gynecologic Oncologists (SGO) have published guidelines for referral to a gynecologic oncologist ( TABLE 3 ). When Im and colleagues reviewed the records of more than 1,000 women who underwent surgery for a pelvic mass at six institutions over 12 months, they found that 70% of premenopausal women and 94% of postmenopausal women who were diagnosed with ovarian cancer were properly referred to a qualified subspecialist.27 “Over”-referral occurred in 30% to 40% of women who had a benign mass, but may be preferable given the importance of proper staging and debulking to survival.
ACOG and the SGO recommend referral for women who have:
- elevated tumor markers
- ascites
- a fixed or nodular mass
- a strong family history of breast or ovarian cancer.
Consider preoperative referral of all high-risk and, probably, intermediate-risk women, depending on the availability of qualified specialists for complete surgical staging.
In addition, women need to be counseled thoroughly about the possibility that a malignancy will be diagnosed by frozen section, necessitating additional surgical procedures.

Technique of laparoscopic adnexectomy
In Case 2, an umbilical site was chosen for the primary cannula. In general, the direction of insertion depends on the patient’s body habitus. Heavier patients have a thicker abdominal wall and an umbilicus below the level of the aortic bifurcation. In these women, the angle of insertion should be adjusted from the usual 45° (for patients of normal weight) to an angle nearer to 90°. Lateral ports are typical, as in Case 1.
Treat every mass like cancer
Laparoscopic excision of an adnexal mass can be safe and effective, with better outcomes and recovery than with laparotomy, provided the surgeon adheres to basic principles ( TABLE 2 ). This means treating every mass as though it is potentially malignant, and thoroughly inspecting the abdominal cavity before and after excision of the mass.
Know the retroperitoneal space
As with Case 1, successful laparoscopic excision of an adnexal mass begins with inspection of the peritoneal cavity, abdominopelvic washings, and identification of both the infundibulopelvic ligament and ureter. Knowledge of the retroperitoneal space can be of great value in difficult cases that involve significant pelvic adhesions or sidewall fibrosis. We generally use a retroperitoneal approach for laparoscopic adnexectomy ( FIGURE 2A ).
In our typical approach, we incise the peritoneum lateral to the uteroovarian ligament and continue the incision up the pelvic sidewall lateral to the infundibulopelvic ligament and up along the paracolic gutter, if needed ( FIGURE 2A ). We then mobilize the medial leaf of the broad ligament from the sidewall using blunt dissection between the external iliac vessels laterally and the ureter medially ( FIGURE 2B ).
Once we have identified the ureter, we use scissors to create a window in the medial leaf of the broad ligament just beneath the gonadal vessels. We then use an energy source to occlude and transect the pedicle. Using this technique, we secure the infundibulopelvic ligaments and safely mobilize the ureter before initiating more aggressive sidewall dissection distally for adhesions or fibrosis.
Once the ureter is mobilized, we excise the involved peritoneum along with the mass. We then seal and transect the uteroovarian ligament.
FIGURE 2 The retroperitoneal approach
Grasp and incise the peritoneum just lateral to the adnexal mass and enter the retroperitoneal space, where loose areolar tissue is visible, with the ureter seen on the medial leaf of the broad ligament.
After dissecting this tissue, identify the ureter and internal iliac vessels.
Remove the mass in a bag
Once the mass is excised, we place it in a laparoscopic bag, as described for Case 1. Solid adnexal masses are problematic because they are not amenable to drainage, and morcellation is usually discouraged. Laparoscopic excision can still be carried out, and a minilaparotomy or posterior colpotomy can be used to extract the mass in a bag. Patients managed in this way still have a complication rate similar to or lower than that of patients undergoing laparotomy for oophorectomy; they also recover faster.
Risks in cases of malignancy
The risk of tumor spillage in laparoscopic surgery can be lowered using laparoscopically guided minilaparotomy techniques. Preoperative rupture appears to be more predictive of outcome.28
The concern about metastatic implants in a laparoscopic port site in patients who have gynecologic cancer is real, with an incidence ranging from 0.97% to 1.1%. The phenomenon usually affects women who had ovarian cancer and is most common after laparoscopy with findings of ascites, carcinomatosis, or persistent disease (in the case of second-look laparoscopy performed after completion of primary therapy for ovarian cancer).
These data suggest that port-site implantation is not a concern that should deter clinicians from laparoscopic evaluation of a suspected ovarian neoplasm unless a patient presents with ascites or carcinomatosis suggestive of advanced disease.29
Data are limited regarding delays in definitive therapy. One study suggests that definitive staging on the day of rupture does not influence overall outcome, but delay by more than 2 weeks may lead to poorer prognosis.30
CASE 2: OUTCOME
Laparoscopy is performed. On initial inspection, the peritoneal cavity is unremarkable. The right ovary is multicystic with normal surface anatomy. The mass is somewhat adherent to the pelvic sidewall. Adnexectomy is performed, and frozen section reveals the mass to be a serous cystadenoma.
The authors report no financial relationships relevant to this article.

Mrs. R is a 29-year-old G1P1 who underwent a right oophorectomy, with a midline incision, for a dermoid cyst at the time of cesarean delivery. She now has a left ovarian cyst.

- How often will a mass be malignant?
- How can we safely remove an adnexal mass to maximize patient safety, reduce overall recovery time, and prevent less favorable outcomes in women who are eventually found to have a malignancy?
A thorough workup and, sometimes, conservative management can prevent unnecessary surgery that may lead to early menopause or surgical complications. And maximizing the use of minimally invasive techniques in women who do require surgery can shorten hospital stay and recovery time. At the time of surgery, careful abdominal entry and meticulous surgical dissection and mass removal can limit the potential risks of laparoscopic excision in women who have an ultimate diagnosis of cancer.
In this article, we review the workup for women who have an adnexal mass, describe patient-selection criteria for laparoscopic surgery, including the risks and benefits of this approach ( TABLE 1 ), and present several techniques to safely manage a mass with potentially malignant histology via laparoscopy.
TABLE 1
There are benefits and risks to managing an adnexal mass laparoscopically
Benefit | Risk |
---|---|
Shorter recovery Fewer adhesions Decreased overall cost Magnification Decreased pain and narcotic use Fewer wound complications | Expensive equipment* Loss of tactile sensation Concern for malignancy Risk of tumor dissemination/spillage/chemical peritonitis Trocar-site metastasis |
*Though greater expense is not a risk per se, it does enter into decision making. |
Begin with the physical
When a woman is known to have a pelvic mass, the aim of the office exam is to 1) identify characteristics that suggest malignancy and 2) rule out nongynecologic causes of the mass. Physical findings that are worrisome for a malignant process include:
- fixed or nodular pelvic mass
- bilateral masses
- nodular abdominal mass
- ascites
- pleural effusion on auscultation or percussion of the lung.
Although these findings can be present under benign conditions, they increase the risk that a malignancy will be detected at surgery.
Other causes of a pelvic mass should also be considered, including infection (pelvic abscess) and tumors of the colon, particularly when the pelvic mass occurs on the left side.
Some symptoms, though vague, are worth noting
Although ovarian cancer was once thought to be a silent disease, recent research has shown that bloating, pelvic or abdominal pain, early satiety, and urinary frequency and urgency are more common among women with ovarian cancer than among healthy controls and patients in high-risk screening clinics.2-4 Although these symptoms are generally nonspecific, they merit attention if they occur more than 12 times a month and have been present for less than 1 year. When they meet these criteria, the symptoms have a sensitivity for diagnosing early- and late-stage ovarian cancer of 56.7% and 79.5%, respectively.4
Sensitivity for the diagnosis of early-stage ovarian cancer may be as high as 80% when the symptom index score is combined with an elevated level of the tumor marker CA 125.3
Transvaginal US is crucial
Transvaginal US is now standard practice to obtain high-resolution images of an adnexal mass. Grayscale US has traditionally been used alone for evaluation.
Specificity is typically lower in women who are premenopausal because many benign lesions, such as endometrioma, have a similar sonographic appearance to cancer.
A number of US scoring algorithms have now been proposed to aid in the triage of women who have an adnexal mass. Sensitivity of these algorithms ranges from 65% to 100%; specificity, from 77% to 95%.5
CA 125 is the standard tumor marker
For the past two decades, CA 125 has been the standard serum marker in the screening of high-risk women for ovarian cancer and the triage of women who have an adnexal mass.
This blood test has been studied widely since its introduction in 1983. It typically has sensitivity of 75% to 85% and specificity of 85% to 95% in identifying women who have ovarian cancer. However, it is elevated in only 50% to 60% of women who have stage I ovarian cancer. Its lack of specificity and poor positive predictive value have kept researchers busy trying to identify other serum markers, for both ovarian cancer and identification of high-risk pelvic masses.
Our recommended workup and management of adnexal masses In postmenopausal women who had a pelvic mass, one study found that a CA 125 level above 65 IU/mL had sensitivity of 71% and specificity of 92.5% in the identification of ovarian cancer.6 Another group found that CA 125 levels above 65 IU/mL were more than 95% sensitive in the diagnosis of ovarian cancer in postmenopausal women.7
Several studies have combined CA 125 with other markers or with US to screen high-risk women or triage those who have an adnexal mass. These studies have shown modest improvements in sensitivity but usually lower specificity than with CA 125 testing alone.
Markers that may be used for suspected sex cord stromas and germ-cell tumors are:
- lactate dehydrogenase (LDH) for dysgerminomas
- alpha-fetoprotein (AFP) and human chorionic gonadotropin (hCG) for yolk sac tumors
- testosterone for Sertoli-Leydig cell tumors
- inhibin A and B for granulosa cell tumors.
An algorithm for working up and managing adnexal masses appears above.
How to gain abdominal access
In the opening case, the patient clearly has a benign mass. The treatment? Safe entry into the peritoneal cavity to remove the cyst and as little normal tissue as possible. This is critical in this patient because she has only one ovary.
Peritoneal access for abdominal and pelvic laparoscopy has been studied widely. Options include:
- direct insertion using a Veress needle
- open laparoscopy
- direct trocar insertion.
The technique usually depends on the preference of the surgeon. The primary goal of abdominal entry is to minimize the risk of injury, particularly unrecognized injury.
Data on complication rates show no definite benefit for open versus closed techniques in the prevention of injury to underlying viscera. However, evidence does suggest that the open technique may lower the risk of major vascular injury.8
We employ direct trocar insertion using radially expanding or optical trocars.
The Veress needle option
When the Veress needle is used to gain intraperitoneal access, data indicate that initial intraperitoneal pressure below 10 mm Hg is a reliable marker for peritoneal entry, even in obese patients.9 Insufflation pressure as high as 25 to 30 mm Hg prior to placement of the initial trocar is safe from a cardiopulmonary standpoint and may allow easier entry with a nonbladed trocar.10
Tests to confirm intraperitoneal placement of the Veress needle, such as the hanging-drop test or saline flush, do not appear to offer any additional useful information.11
Open laparoscopy is suitable when adhesions are unlikely
Open laparoscopy is typically performed by making a minilaparotomy incision at the umbilicus and then dissecting and entering the peritoneal cavity. A blunt-tip trocar is inserted.
The disadvantage of this approach is that there may be extensive adhesions under the umbilicus, and it is difficult to dissect such adhesions sufficiently to introduce a cannula and laparoscope. Adhesions left behind often obscure the field of view after introduction of the trocar.
Our preference? Left upper-quadrant insertion
In Case 1, the previous midline incision mandates an alternative approach. When abdominal entry at the umbilicus is unsuccessful or potentially difficult because of an earlier midline incision, umbilical hernia repair, or history of multiple lower abdominal or pelvic surgeries, a left upper-quadrant insertion is useful. It is, in fact, our preferred technique, and involves a small incision at the midclavicular line 5 cm below the left costal margin, at a site called Palmer’s point.
The direction of insertion usually ranges from 45° to 90°, depending on the patient’s body weight. If the trocar is placed properly, the closest organs are the stomach and the left lobe of the liver (4 to 6 cm).12 Given the stomach’s close proximity, it should be decompressed with an orogastric tube prior to trocar insertion.
Several studies have demonstrated the safety and efficacy of this entry technique.12-14 It can be helpful in cases that involve difficult access. We usually use a 5-mm primary trocar site for a 5-mm laparoscope. Modern optics allow for a pristine view with these small scopes, eliminating the need to close fascia and perhaps causing less pain at the incision.
Accessory trocar sites facilitate complex technique
We usually use three accessory sites. Two of them are lower-quadrant ports that are placed 2 cm medial and 2 cm cephalad to the anterior superior iliac spine. This area generally lies well away from the inferior epigastric vessels and remains above the area of the ilioinguinal and iliohypogastric nerves, making it a safer point of insertion.15 One trocar is 5 mm in size and the other is 10 mm. The larger one is used to extract the specimen.
We place an additional 5-mm port lateral to the rectus muscle at the level of the umbilicus. This allows the principal surgeon to use two instruments (a toothed forceps and scissors) comfortably while the assistant holds the laparoscope and assists with a grasper.
Does the type of trocar matter?
No randomized studies have directly compared all types of trocars. Options include:
- a pyramidal tip (as in reusable trocars) or shielded tip
- radial expansion
- visible entry
- blunt (Hasson-type) trocar.
Safety data on direct comparison of trocars are limited, but it appears that a radially expanding trocar may offer less port-site pain and potentially less bleeding than a traditional cutting trocar.16 Moreover, the rate of hernia at the port site appears to be relatively low with a radially expanding trocar, even when fascia is left unclosed at a 10-mm site.17
None of these trocars appears to be clearly superior at avoiding visceral or vascular injury.
Technique of laparoscopic cyst removal
A video clip of the surgery is linked to this article in the Video Library at www.obgmanagement.com. In this case, a trocar was inserted in the left upper quadrant, and a laparoscopic cystectomy was initiated using the trocars already specified.
The peritoneal cavity and adnexa were inspected, followed by pelvic washings, as detailed in TABLE 2 . Next, the ovarian cortex was incised ( FIGURE 1A ) with scissors using bipolar or unipolar energy, typically at a low power setting, such as 12 to 15 watts.
It was relatively easy to develop a tissue plane between the cortex and underlying dermoid cyst using simple or aqua-dissection ( FIGURE 1B and C ). The cyst was enucleated without rupture and inserted into a specimen bag through a 10-mm port ( FIGURE 1D ). (The specimen bags generally are available in 10-mm and 15-mm sizes.) Once the trocar was removed, the entire specimen was brought out through the incision ( FIGURE 1E ).
Cystic masses can generally be carefully aspirated using a laparoscopic needle or angiocath, or they can be incised and drained using a standard suction device. Manufacturers of most specimen bags do not recommend the morcellation of tissue within the bag because of the potential for rupture of the bag with tumor spillage or injury to underlying structures.
Occasionally, the mass remains too large to remove after drainage of the cyst fluid. Remedies include enlarging the port site with a scalpel or using a gallbladder speculum to increase the diameter of the port site ( FIGURE 1E ). If possible, the incision should be large enough to deliver the entire bag intact. Use of excessive force will rupture the bag and may cause the specimen to be lost or malignant cells to be inadvertently spilled (in the case of a cancer diagnosis).

CASE 1: OUTCOME
The patient’s cyst is removed intact and she is discharged home. Rupture of a dermoid cyst is not associated with any problems as long as copious irrigation is used to aspirate the cyst content.18 Other cysts, such as endometriomas, may not be as easily dissected, and rupture is inevitable.
CASE 2: Symptoms suggestive of cancer
Mrs. B is a 47-year-old woman who reports abdominal bloating for the past 3 weeks. She also complains of early satiety and occasional constipation. She has no history of cancer, but her sister was given a diagnosis of breast cancer at 41 years of age, and her maternal aunt had breast cancer at 55 years.
Mrs. B is moderately obese, with a nontender abdomen and no palpable mass. Her pelvic exam also is negative for a mass or nodularity, but the extent of the exam is limited by body habitus. Her physician orders a transvaginal US, which reveals a 6-cm complex mass with thin septation and a 1-cm solid nodule, with no definite blood flow. The patient’s CA 125 level is 80 IU/mL, which we consider to be within the low-risk range for a premenopausal woman.
The patient is counseled about the need to have the mass removed and is scheduled for laparoscopic right salpingooophorectomy. Given the family history of breast cancer, the physician also requests consultation with a gynecologic oncologist, who agrees to assist with surgery and perform a laparotomy and staging in the event that a malignancy is diagnosed.
Is the mass likely to be malignant?
Given the patient’s family history of breast cancer, the recent onset of symptoms associated with ovarian cancer,2 and the characteristics of the mass (complex, with a nodule), malignancy is possible. This patient has an intermediate risk of cancer and requires additional counseling and planning.
However, most women who undergo laparoscopy for removal of an adnexal mass have benign pathologic findings.
What is the real risk of ovarian cancer?
The lifetime risk of developing ovarian cancer in the general population remains stable at approximately 1 in 70 women, with a mean age at diagnosis of 63 years.19 Ninety percent of ovarian cancer cases are sporadic, and less than 10% can be linked to genetic syndromes.
Women who have mutations in the BRCA1 gene carry a lifetime risk of ovarian cancer of up to 50%, and women who have mutations in BRCA2 have a lifetime risk of up to 25%.20,21 Women who have mutations associated with Lynch II syndrome or Hereditary Nonpolyposis Colorectal Cancer syndrome may have a lifetime risk of ovarian cancer of 12%.22,23
Some women who have a strong family history of breast and ovarian cancer do not carry a known mutation, but are likely to be at increased risk.
Additional risk factors known to be associated with ovarian cancer are nulliparity and infertility. However, the single most important risk factor for epithelial ovarian cancer is age.
Risk-reducing strategies include:
In the case of PBSO, it is imperative to ensure that all ovarian surface epithelium is removed. This means excising the infundibulopelvic ligament at least 1.5 cm above the proximal end of the ovary and excising any adjacent tissue to which the ovary is adherent (including pelvic sidewall peritoneum). Both requirements are easily achieved using the techniques outlined here.
Who should perform surgery?
The American College of Obstetricians and Gynecologists (ACOG) and the Society of Gynecologic Oncologists (SGO) have published guidelines for referral to a gynecologic oncologist ( TABLE 3 ). When Im and colleagues reviewed the records of more than 1,000 women who underwent surgery for a pelvic mass at six institutions over 12 months, they found that 70% of premenopausal women and 94% of postmenopausal women who were diagnosed with ovarian cancer were properly referred to a qualified subspecialist.27 “Over”-referral occurred in 30% to 40% of women who had a benign mass, but may be preferable given the importance of proper staging and debulking to survival.
ACOG and the SGO recommend referral for women who have:
- elevated tumor markers
- ascites
- a fixed or nodular mass
- a strong family history of breast or ovarian cancer.
Consider preoperative referral of all high-risk and, probably, intermediate-risk women, depending on the availability of qualified specialists for complete surgical staging.
In addition, women need to be counseled thoroughly about the possibility that a malignancy will be diagnosed by frozen section, necessitating additional surgical procedures.
TABLE 3

Is she premenopausal? Then refer her when… | Is she postmenopausal? Then refer her when… |
---|---|
CA125 >200 IU/mL Ascites is present Evidence of abdominal or distant metastasis on exam or imaging Family history of breast or ovarian cancer in a first-degree relative | CA125 >35 IU/mL Ascites is present Nodular or fixed pelvic mass Evidence of abdominal or distant metastasis on exam or imaging Family history of breast or ovarian cancer in a first-degree relative |
Technique of laparoscopic adnexectomy
In Case 2, an umbilical site was chosen for the primary cannula. In general, the direction of insertion depends on the patient’s body habitus. Heavier patients have a thicker abdominal wall and an umbilicus below the level of the aortic bifurcation. In these women, the angle of insertion should be adjusted from the usual 45° (for patients of normal weight) to an angle nearer to 90°. Lateral ports are typical, as in Case 1.
Treat every mass like cancer
Laparoscopic excision of an adnexal mass can be safe and effective, with better outcomes and recovery than with laparotomy, provided the surgeon adheres to basic principles ( TABLE 2 ). This means treating every mass as though it is potentially malignant, and thoroughly inspecting the abdominal cavity before and after excision of the mass.
Know the retroperitoneal space
As with Case 1, successful laparoscopic excision of an adnexal mass begins with inspection of the peritoneal cavity, abdominopelvic washings, and identification of both the infundibulopelvic ligament and ureter. Knowledge of the retroperitoneal space can be of great value in difficult cases that involve significant pelvic adhesions or sidewall fibrosis. We generally use a retroperitoneal approach for laparoscopic adnexectomy ( FIGURE 2A ).
In our typical approach, we incise the peritoneum lateral to the uteroovarian ligament and continue the incision up the pelvic sidewall lateral to the infundibulopelvic ligament and up along the paracolic gutter, if needed ( FIGURE 2A ). We then mobilize the medial leaf of the broad ligament from the sidewall using blunt dissection between the external iliac vessels laterally and the ureter medially ( FIGURE 2B ).
Once we have identified the ureter, we use scissors to create a window in the medial leaf of the broad ligament just beneath the gonadal vessels. We then use an energy source to occlude and transect the pedicle. Using this technique, we secure the infundibulopelvic ligaments and safely mobilize the ureter before initiating more aggressive sidewall dissection distally for adhesions or fibrosis.
Once the ureter is mobilized, we excise the involved peritoneum along with the mass. We then seal and transect the uteroovarian ligament.
FIGURE 2 The retroperitoneal approach
Grasp and incise the peritoneum just lateral to the adnexal mass and enter the retroperitoneal space, where loose areolar tissue is visible, with the ureter seen on the medial leaf of the broad ligament.
After dissecting this tissue, identify the ureter and internal iliac vessels.
Remove the mass in a bag
Once the mass is excised, we place it in a laparoscopic bag, as described for Case 1. Solid adnexal masses are problematic because they are not amenable to drainage, and morcellation is usually discouraged. Laparoscopic excision can still be carried out, and a minilaparotomy or posterior colpotomy can be used to extract the mass in a bag. Patients managed in this way still have a complication rate similar to or lower than that of patients undergoing laparotomy for oophorectomy; they also recover faster.
Risks in cases of malignancy
The risk of tumor spillage in laparoscopic surgery can be lowered using laparoscopically guided minilaparotomy techniques. Preoperative rupture appears to be more predictive of outcome.28
The concern about metastatic implants in a laparoscopic port site in patients who have gynecologic cancer is real, with an incidence ranging from 0.97% to 1.1%. The phenomenon usually affects women who had ovarian cancer and is most common after laparoscopy with findings of ascites, carcinomatosis, or persistent disease (in the case of second-look laparoscopy performed after completion of primary therapy for ovarian cancer).
These data suggest that port-site implantation is not a concern that should deter clinicians from laparoscopic evaluation of a suspected ovarian neoplasm unless a patient presents with ascites or carcinomatosis suggestive of advanced disease.29
Data are limited regarding delays in definitive therapy. One study suggests that definitive staging on the day of rupture does not influence overall outcome, but delay by more than 2 weeks may lead to poorer prognosis.30
CASE 2: OUTCOME
Laparoscopy is performed. On initial inspection, the peritoneal cavity is unremarkable. The right ovary is multicystic with normal surface anatomy. The mass is somewhat adherent to the pelvic sidewall. Adnexectomy is performed, and frozen section reveals the mass to be a serous cystadenoma.

ROUNDTABLE PART 2 OF 2: Using mesh to repair prolapse: Averting, managing complications
Hear Dr Phillips discuss the key points of this series
Vaginal placement of mesh for the correction of pelvic organ prolapse is not an entirely benign procedure. As Mickey M. Karram, MD, and an expert panel discuss in this article—the second of a two-part series—complications secondary to mesh placement can be a challenge to correct and often make life miserable for patients who experience them. Here, these experts address mesh erosion, extrusion, and other serious complications; discuss ways to prevent them; and offer strategies for managing them when they arise.
In Part 1, which appeared in the January 2009 issue of OBG Management, the panel discussed the increasing use of mesh in prolapse repair—in particular, the proliferation of mesh kits.
How common is erosion?
DR. KARRAM: The literature seems to indicate that, even in the best of hands, there is an extrusion, or erosion, rate of between 5% and 17% when mesh is used. Would you agree with this statistic?
DR. LUCENTE: Not completely. The vaginal exposure rate can be as low as 2%, as reported by our center and others, when the mesh is properly placed below all histologic layers of the vaginal wall, as it is when it is “delivered” to the pelvis via the transabdominal route.1,2
At the other end of the scale, an exposure rate above 17% has been reported when mesh is improperly placed within the vaginal wall—that is, just below the mucosa, as some surgeons have described in the methodology section of their abstract or article.3,4
MICKEY M. KARRAM, MD, moderator, is Director of Urogynecology at Good Samaritan Hospital and Voluntary Professor of ObGyn at the University of Cincinnati School of Medicine in Cincinnati, Ohio.
SHLOMO RAZ, MD, is Professor of Urology and Chief of Pelvic Medicine and Reconstructive Urology at UCLA School of Medicine in Los Angeles.
VINCENT LUCENTE, MD, MBA, is Founder and Director of the Institute for Female Pelvic Medicine and Reconstructive Surgery in Allentown, Pa, and Clinical Professor of ObGyn at Temple University School of Medicine in Philadelphia.
MARK D. WALTERS, MD, is Professor and Vice Chair of Gynecology, Section of Urogynecology and Reconstructive Pelvic Surgery, Department of Obstetrics and Gynecology, at the Cleveland Clinic in Cleveland, Ohio.
We have found that complete, full-thickness dissection of the vaginal wall into the true pelvic space (vesicovaginal and rectovaginal), utilizing small vaginal incisions and limiting hysterectomy and the trimming of vaginal mucosa, can promote a very low vaginal-exposure rate.
DR. WALTERS: Some surgeons tell me that their own extrusion or erosion rate is lower than the published rate of 5% to 17%, but it is impossible to be certain of the long-term outcome in any patient unless she is followed carefully. The patient may consult another physician about her complications. The primary surgeon—even an expert—often does not know the actual mesh complication rate.
That said, I am sure that some surgeons are particularly adept at using mesh kits for prolapse repair, thereby keeping their mesh complication rate low. The 5% to 17% number is what most gynecologic surgeons should expect for their patients.
DR. RAZ: The complication rates are clearly underreported since very few centers of excellence report on complications and the majority of users don’t report them. Also, the reported complication rate concerns short-term erosion. I imagine that, as time passes and vaginal tissue becomes more atrophic, the incidence of erosion will increase.
Are simple measures enough to resolve erosion?
DR. KARRAM: There seems to be a general perception that most extrusions or erosions can be easily managed in the office by placing estrogen or trimming. In our experience, that approach has been successful in a minority of cases only.
What have you seen?
DR. WALTERS: At the Cleveland Clinic, as at most tertiary care referral centers, we often see the worst cases of extrusion or erosion related to mesh. Estrogen helps in some cases of simple mesh exposure, especially after sacrocolpopexy. If estrogen is going to be effective, however, the problem should clear up relatively quickly; if it isn’t effective after a month or two of therapy, estrogen is unlikely to ever be successful.
When it comes to related problems, such as ridges or strictures in the vagina, dyspareunia, penile pain with insertion, and vaginal burning pain, I have not found simple trimming and estrogen to be effective.
DR. KARRAM: It’s also unlikely that simple excision or placement of estrogen will be successful over the long term. When an extrusion or erosion occurs, we are generally seeing only the tip of the iceberg. That’s because mesh is placed in a certain plane. Although only part of the mesh may be exposed, the entire mesh is likely to be affected because it lies in the same plane.
Also, because of the special nature of vaginal flora, it is unlikely that a foreign body is going to be successfully managed by simple excision or placement of estrogen.
DR. LUCENTE: Management of vaginal exposure really depends on the size of the exposure, its location, and whether there is underlying infection or ischemia of host tissue. When the exposure is small (<1 cm in diameter) and in the midline, with the mesh lying flat below the plane of the vaginal wall, we have been very successful using a conservative approach.
However, even the tiniest of exposures needs to be surgically excised if it traverses the vaginal sulcus. Obviously, any mesh erosion into viscera such as the bladder and bowel also requires surgical intervention. Host-tissue factors always play a contributing role.
I also want to point out that the manner in which exposure is managed depends to some extent on whether the mesh was properly placed. Exposures that arise when mesh is implanted improperly are difficult to correct and usually require complete removal.
Although we, too, started off with an exposure rate around 8%, it is now very low, thanks to technical advancements.
DR. RAZ: A very small vaginal erosion of a mesh sling can sometimes be managed in the office by excision. The cases referred to our service generally involve more extensive areas of exposure that will not be resolved by local treatment.
Is risk of injury operator-dependent?
DR. KARRAM: We’re all seeing very severe complications secondary to mesh placement. Would each of you give your opinion as to whether the severe complications such as significant pain, dyspareunia, and injury of important structures are mostly technical or inherent to mesh placement. Would they happen in the best of hands?
DR. LUCENTE: The more severe complications, for the most part, are very much related to technique. Not that they cannot happen in the very best of hands, but they are extremely rare when technique is meticulous.
Over a 4-year period, after well over 1,000 transvaginal mesh surgeries at our center, we had no death, ICU admission, or transfusion, and our intraoperative complication rate was only 3%, most commonly involving simple cystotomy without long-term consequence. This compares very favorably to the nearly 12% complication rate reported recently in the CARE trial for abdominal sacral colpopexy.5
Our primary challenge today is preventing postoperative dyspareunia. Our rate of new-onset dyspareunia is approximately 3.5%. This complication is, I think, more likely to be related to the inherent material properties of mesh, such as elasticity and flexural rigidity, and to host-tissue response to the material itself.
DR. RAZ: I think that the majority of complications are operator-dependent. Thin dissection of the vaginal wall and unrecognized bladder, urethral, and vaginal perforation are the most common reasons for the complications. Mesh does not move after surgery; if there is a problem, it means that the mesh was misplaced.
Another problem is that industry, in an effort to sell more kits, is pushing physicians who are unfamiliar with the principles of pelvic reconstruction to perform this complex procedure. Repair of major vaginal prolapse is not a simple sling procedure.
In addition, there is a greater likelihood of complications in patients who have severe atrophic tissues. These patients should not be candidates for mesh reconstruction.
DR. WALTERS: Many of the complications that we see with mesh are certainly operator-dependent. For example, mesh that is placed under too much tension leaves the vagina tight and stiff, and mesh that is placed with ripples and ridges causes irregularities in the vagina that are often painful, especially during intercourse.
I do not believe that mesh “erodes” into the bladder, urethra, or rectum, but that it is placed there inadvertently and overlooked intraoperatively (FIGURES 1 and 2), Visceral erosion can occur if the primary surgeon made a cystotomy or proctotomy before proceeding with the mesh kit, and the mesh eventually wore through the repaired area.
There are also some problems that are inherent to mesh, and that occur even in the best hands and after surgeries that are performed very competently. Some mesh exposures are inevitable, as are some cases of dyspareunia and rare cases of vaginal burning and pain. In addition, I am seeing more de novo SUI [stress urinary incontinence] with anterior mesh kits. Although this is not really a complication, it does lead to dissatisfaction in patients and merits efforts to prevent it.
DR. KARRAM: Yes. With the current state of mesh, I believe pain and dyspareunia are almost inevitable in some cases.
DR. LUCENTE: Another problem that is currently underaddressed is scar plating along the surface of the mesh. Such plating forms more readily in the absence of mechanical movement or distention during the early stages of wound healing. To make a comparison, even the best reconstructive orthopedic surgeons cannot achieve optimal functional outcomes with an implant surgery without intense postoperative physical therapy, which may simply involve range of motion or movement.
Most everyone is familiar with the capsular fibrosis and contraction that develop around a breast implant if there isn’t immediate postoperative massaging of the breast tissue and implant during wound repair. I am confident that the rate of dyspareunia will decline over time if specialists in reconstructive pelvic surgery pay closer attention to optimizing vaginal length, preserving the cervix (in women with relatively shorter vaginal length), and ensuring optimal apical attachment (that is, above the ischial spine) in younger, sexually active patients.
DR. RAZ: I think it is the surgeon rather than the surgery who causes most complications. In its effort to sell kits, industry sometimes puts them in the hands of surgeons who are not well prepared for the task. This operation can be quite complex, and you cannot create a pelvic surgeon from a physician who is unfamiliar with the anatomy. If you cannot manage the potential complications, you should not perform this type of surgery.
FIGURE 1 When mesh “erodes” into the urethra
Two images of mesh in the urethra. There is some uncertainty here whether mesh that has penetrated the urethra eroded through vaginal tissue or was placed there inadvertently and overlooked intraoperatively.
FIGURE 2 Mesh in the bladder
A segment of tension-free vaginal tape has penetrated into the bladder.
Should mesh be removed at the time of injury?
DR. KARRAM: As we discuss specific complications, let’s start with the most severe, which I would say relate to the inadvertent placement of mesh through important structures such as bowel, bladder, or ureters. If this were to happen and be diagnosed intraoperatively, what would you recommend that the surgeon do—abort the procedure or simply remove the mesh or trocar and attempt to pass it again safely?
DR. LUCENTE: That is a difficult question to answer because so much depends on various intraoperative factors.
I am much more comfortable proceeding with surgery after intraoperative bladder injury than after bowel or rectal injury. We have successfully corrected cystotomies that were small, did not encroach on the ureter, and were easily repaired without tension—and we have seen no fistula formation as a result.
The key is to maintain a high index of suspicion throughout the procedure. We have always diagnosed injuries before mesh is delivered—either during dissection or during passage of the needle or trocar. We have not experienced any ureteral injuries aside from “kinking” of one ureter, which was easily corrected with simple readjustment of the mesh.
If, at any time, we were concerned about potential infection, fistula, or a more severe complication that would be aggravated by proceeding with the operation, we would abort the procedure. However, we would be likely to proceed with an alternative operation to address the pelvic-support defect so that the patient would not awaken with intraoperative injury and no surgical treatment for her primary complaint.
We conduct informed consent in such a way as to preserve our flexibility to adapt the surgical plan to execute the reparative work that is necessary despite the development of a non–life-threatening complication during surgery. In the event of any injury to the bowel that would involve gross spillage of fecal material, of course, I would abort placement of synthetic mesh.
DR. WALTERS: If I placed one of the trocars through the bladder or bowel, I would probably remove it, reposition it, and continue with the surgery. With bladder perforation, this approach is generally no problem, but I would usually leave a Foley catheter in place for 1 week of continuous bladder drainage.
If I placed the trocar through the rectum, I would probably oversew the proctotomy, irrigate the space, and continue with the mesh repair. If I had an outright laceration in the bladder or rectum as part of the dissection, I would repair it and consider converting the surgery to prolapse repair without mesh.
The most dreaded complication: the foreshortened vagina
DR. KARRAM: It would seem that the most difficult complication to deal with is the foreshortened, firm, painful vagina. A patient who has these problems may be perceived, at times, as a pelvic “cripple.” Is this an accepted, albeit rare, complication? Or can it be avoided?
DR. LUCENTE: This is the most feared complication arising from the use of synthetic mesh. I do believe it can almost always be avoided—but I never say never. The key is to pay full attention to considerations of vaginal length before surgery, including, first, preservation of the cervix, and, second, placing the mesh loosely, properly sized, and attached with optimization of apical support to preserve vaginal length.
I also believe that use of second-generation meshes that are lighter, more elastic, and more flexible helps reduce this complication when the mesh is properly placed by a surgeon well trained in the technique.
When the vagina is foreshortened, the sooner it is revised, the better the chance that pain will resolve, whether the mesh is removed or released.
DR. RAZ: Mesh infection, capsular formation, dissection of a thin vaginal wall, and excess vaginal-wall excision lead to the short, firm, and painful vagina. The use and abuse of mesh has created a new subspecialty to manage mesh complications. The PFS syndrome (painful, firm, and short vagina) is one of the most difficult complications to treat because, in many cases, it cannot be reversed without major surgery.
DR. WALTERS: Women who have a foreshortened, firm, or painful vagina after mesh augmentation almost always need to have the mesh removed with reconstruction of the vaginal canal. I have never seen a successful outcome in this type of patient without complete or near-complete removal of the mesh.

We have found that complete, full-thickness dissection of the vaginal wall into the true pelvic space (vesicovaginal and rectovaginal), utilizing small vaginal incisions and limiting hysterectomy and the trimming of vaginal mucosa, can promote a very low vaginal-exposure rate.
DR. WALTERS: Some surgeons tell me that their own extrusion or erosion rate is lower than the published rate of 5% to 17%, but it is impossible to be certain of the long-term outcome in any patient unless she is followed carefully. The patient may consult another physician about her complications. The primary surgeon—even an expert—often does not know the actual mesh complication rate.
That said, I am sure that some surgeons are particularly adept at using mesh kits for prolapse repair, thereby keeping their mesh complication rate low. The 5% to 17% number is what most gynecologic surgeons should expect for their patients.
DR. RAZ: The complication rates are clearly underreported since very few centers of excellence report on complications and the majority of users don’t report them. Also, the reported complication rate concerns short-term erosion. I imagine that, as time passes and vaginal tissue becomes more atrophic, the incidence of erosion will increase.
Are simple measures enough to resolve erosion?
DR. KARRAM: There seems to be a general perception that most extrusions or erosions can be easily managed in the office by placing estrogen or trimming. In our experience, that approach has been successful in a minority of cases only.
What have you seen?
DR. WALTERS: At the Cleveland Clinic, as at most tertiary care referral centers, we often see the worst cases of extrusion or erosion related to mesh. Estrogen helps in some cases of simple mesh exposure, especially after sacrocolpopexy. If estrogen is going to be effective, however, the problem should clear up relatively quickly; if it isn’t effective after a month or two of therapy, estrogen is unlikely to ever be successful.
When it comes to related problems, such as ridges or strictures in the vagina, dyspareunia, penile pain with insertion, and vaginal burning pain, I have not found simple trimming and estrogen to be effective.
DR. KARRAM: It’s also unlikely that simple excision or placement of estrogen will be successful over the long term. When an extrusion or erosion occurs, we are generally seeing only the tip of the iceberg. That’s because mesh is placed in a certain plane. Although only part of the mesh may be exposed, the entire mesh is likely to be affected because it lies in the same plane.
Also, because of the special nature of vaginal flora, it is unlikely that a foreign body is going to be successfully managed by simple excision or placement of estrogen.
DR. LUCENTE: Management of vaginal exposure really depends on the size of the exposure, its location, and whether there is underlying infection or ischemia of host tissue. When the exposure is small (<1 cm in diameter) and in the midline, with the mesh lying flat below the plane of the vaginal wall, we have been very successful using a conservative approach.
However, even the tiniest of exposures needs to be surgically excised if it traverses the vaginal sulcus. Obviously, any mesh erosion into viscera such as the bladder and bowel also requires surgical intervention. Host-tissue factors always play a contributing role.
I also want to point out that the manner in which exposure is managed depends to some extent on whether the mesh was properly placed. Exposures that arise when mesh is implanted improperly are difficult to correct and usually require complete removal.
Although we, too, started off with an exposure rate around 8%, it is now very low, thanks to technical advancements.
DR. RAZ: A very small vaginal erosion of a mesh sling can sometimes be managed in the office by excision. The cases referred to our service generally involve more extensive areas of exposure that will not be resolved by local treatment.
Is risk of injury operator-dependent?
DR. KARRAM: We’re all seeing very severe complications secondary to mesh placement. Would each of you give your opinion as to whether the severe complications such as significant pain, dyspareunia, and injury of important structures are mostly technical or inherent to mesh placement. Would they happen in the best of hands?
DR. LUCENTE: The more severe complications, for the most part, are very much related to technique. Not that they cannot happen in the very best of hands, but they are extremely rare when technique is meticulous.
Over a 4-year period, after well over 1,000 transvaginal mesh surgeries at our center, we had no death, ICU admission, or transfusion, and our intraoperative complication rate was only 3%, most commonly involving simple cystotomy without long-term consequence. This compares very favorably to the nearly 12% complication rate reported recently in the CARE trial for abdominal sacral colpopexy.5
Our primary challenge today is preventing postoperative dyspareunia. Our rate of new-onset dyspareunia is approximately 3.5%. This complication is, I think, more likely to be related to the inherent material properties of mesh, such as elasticity and flexural rigidity, and to host-tissue response to the material itself.
DR. RAZ: I think that the majority of complications are operator-dependent. Thin dissection of the vaginal wall and unrecognized bladder, urethral, and vaginal perforation are the most common reasons for the complications. Mesh does not move after surgery; if there is a problem, it means that the mesh was misplaced.
Another problem is that industry, in an effort to sell more kits, is pushing physicians who are unfamiliar with the principles of pelvic reconstruction to perform this complex procedure. Repair of major vaginal prolapse is not a simple sling procedure.
In addition, there is a greater likelihood of complications in patients who have severe atrophic tissues. These patients should not be candidates for mesh reconstruction.
DR. WALTERS: Many of the complications that we see with mesh are certainly operator-dependent. For example, mesh that is placed under too much tension leaves the vagina tight and stiff, and mesh that is placed with ripples and ridges causes irregularities in the vagina that are often painful, especially during intercourse.
I do not believe that mesh “erodes” into the bladder, urethra, or rectum, but that it is placed there inadvertently and overlooked intraoperatively (FIGURES 1 and 2), Visceral erosion can occur if the primary surgeon made a cystotomy or proctotomy before proceeding with the mesh kit, and the mesh eventually wore through the repaired area.
There are also some problems that are inherent to mesh, and that occur even in the best hands and after surgeries that are performed very competently. Some mesh exposures are inevitable, as are some cases of dyspareunia and rare cases of vaginal burning and pain. In addition, I am seeing more de novo SUI [stress urinary incontinence] with anterior mesh kits. Although this is not really a complication, it does lead to dissatisfaction in patients and merits efforts to prevent it.
DR. KARRAM: Yes. With the current state of mesh, I believe pain and dyspareunia are almost inevitable in some cases.
DR. LUCENTE: Another problem that is currently underaddressed is scar plating along the surface of the mesh. Such plating forms more readily in the absence of mechanical movement or distention during the early stages of wound healing. To make a comparison, even the best reconstructive orthopedic surgeons cannot achieve optimal functional outcomes with an implant surgery without intense postoperative physical therapy, which may simply involve range of motion or movement.
Most everyone is familiar with the capsular fibrosis and contraction that develop around a breast implant if there isn’t immediate postoperative massaging of the breast tissue and implant during wound repair. I am confident that the rate of dyspareunia will decline over time if specialists in reconstructive pelvic surgery pay closer attention to optimizing vaginal length, preserving the cervix (in women with relatively shorter vaginal length), and ensuring optimal apical attachment (that is, above the ischial spine) in younger, sexually active patients.
DR. RAZ: I think it is the surgeon rather than the surgery who causes most complications. In its effort to sell kits, industry sometimes puts them in the hands of surgeons who are not well prepared for the task. This operation can be quite complex, and you cannot create a pelvic surgeon from a physician who is unfamiliar with the anatomy. If you cannot manage the potential complications, you should not perform this type of surgery.
FIGURE 1 When mesh “erodes” into the urethra
Two images of mesh in the urethra. There is some uncertainty here whether mesh that has penetrated the urethra eroded through vaginal tissue or was placed there inadvertently and overlooked intraoperatively.
FIGURE 2 Mesh in the bladder
A segment of tension-free vaginal tape has penetrated into the bladder.
Should mesh be removed at the time of injury?
DR. KARRAM: As we discuss specific complications, let’s start with the most severe, which I would say relate to the inadvertent placement of mesh through important structures such as bowel, bladder, or ureters. If this were to happen and be diagnosed intraoperatively, what would you recommend that the surgeon do—abort the procedure or simply remove the mesh or trocar and attempt to pass it again safely?
DR. LUCENTE: That is a difficult question to answer because so much depends on various intraoperative factors.
I am much more comfortable proceeding with surgery after intraoperative bladder injury than after bowel or rectal injury. We have successfully corrected cystotomies that were small, did not encroach on the ureter, and were easily repaired without tension—and we have seen no fistula formation as a result.
The key is to maintain a high index of suspicion throughout the procedure. We have always diagnosed injuries before mesh is delivered—either during dissection or during passage of the needle or trocar. We have not experienced any ureteral injuries aside from “kinking” of one ureter, which was easily corrected with simple readjustment of the mesh.
If, at any time, we were concerned about potential infection, fistula, or a more severe complication that would be aggravated by proceeding with the operation, we would abort the procedure. However, we would be likely to proceed with an alternative operation to address the pelvic-support defect so that the patient would not awaken with intraoperative injury and no surgical treatment for her primary complaint.
We conduct informed consent in such a way as to preserve our flexibility to adapt the surgical plan to execute the reparative work that is necessary despite the development of a non–life-threatening complication during surgery. In the event of any injury to the bowel that would involve gross spillage of fecal material, of course, I would abort placement of synthetic mesh.
DR. WALTERS: If I placed one of the trocars through the bladder or bowel, I would probably remove it, reposition it, and continue with the surgery. With bladder perforation, this approach is generally no problem, but I would usually leave a Foley catheter in place for 1 week of continuous bladder drainage.
If I placed the trocar through the rectum, I would probably oversew the proctotomy, irrigate the space, and continue with the mesh repair. If I had an outright laceration in the bladder or rectum as part of the dissection, I would repair it and consider converting the surgery to prolapse repair without mesh.
The most dreaded complication: the foreshortened vagina
DR. KARRAM: It would seem that the most difficult complication to deal with is the foreshortened, firm, painful vagina. A patient who has these problems may be perceived, at times, as a pelvic “cripple.” Is this an accepted, albeit rare, complication? Or can it be avoided?
DR. LUCENTE: This is the most feared complication arising from the use of synthetic mesh. I do believe it can almost always be avoided—but I never say never. The key is to pay full attention to considerations of vaginal length before surgery, including, first, preservation of the cervix, and, second, placing the mesh loosely, properly sized, and attached with optimization of apical support to preserve vaginal length.
I also believe that use of second-generation meshes that are lighter, more elastic, and more flexible helps reduce this complication when the mesh is properly placed by a surgeon well trained in the technique.
When the vagina is foreshortened, the sooner it is revised, the better the chance that pain will resolve, whether the mesh is removed or released.
DR. RAZ: Mesh infection, capsular formation, dissection of a thin vaginal wall, and excess vaginal-wall excision lead to the short, firm, and painful vagina. The use and abuse of mesh has created a new subspecialty to manage mesh complications. The PFS syndrome (painful, firm, and short vagina) is one of the most difficult complications to treat because, in many cases, it cannot be reversed without major surgery.
DR. WALTERS: Women who have a foreshortened, firm, or painful vagina after mesh augmentation almost always need to have the mesh removed with reconstruction of the vaginal canal. I have never seen a successful outcome in this type of patient without complete or near-complete removal of the mesh.

ROUNDTABLE: PART 1 OF 2: Using mesh to repair prolapse calls for more than a kit—it takes skill

Mesh kits for repairing prolapse are proliferating like crazy, just as they did for midurethral sling procedures. But mesh augmentation of prolapse surgeries requires more than a prepackaged assortment of tools and materials. In this article, moderator Mickey M. Karram, MD, and a panel of nationally recognized urogynecologists and urologists describe the literature on mesh augmentation and discuss indications, contraindications, techniques, applicable cases, and the considerable training required.
In Part 2, which will appear in the February issue of OBG Management, the panel tackles the thorny topic of complications, including erosion, extrusion, foreshortening of the vagina, dyspareunia, and pain. Their discussion focuses on ways to avoid these problems, and methods for correcting them.
Do we have enough data?
DR. KARRAM: To start, let’s quickly review the peer-reviewed literature on the use of mesh augmentation during surgery for pelvic organ prolapse.
DR. WALTERS: Until recently, most data concerned open abdominal sacrocolpopexy (ASC) using polypropylene or Merseline mesh. There is significant clinical experience with this operation, and multiple cohort studies show long-term cure rates of 78% to 100% for apical prolapse.1
At least two randomized controlled trials have compared open ASC with sutured vaginal colpopexy procedures, and ASC is certainly equal to—perhaps better than—all transvaginal sutured repairs.2,3
With ASC, most recurrences affect the distal half of the vagina and involve one or more of the following:
- anterior or posterior vaginal wall prolapse (or both)
- stress urinary incontinence (SUI)
- distal rectocele.1,3
Mesh erosion occurs in 3.4% of cases and is usually easily managed.1 Other complications, including bowel injury, tend to be related to access, regardless of whether the operation is performed via laparotomy or laparoscopy.
Robotic sacrocolpopexy has become popular in recent years, and we will probably see data on this approach as we gain experience.
When it comes to vaginal mesh kits, the peer-reviewed literature is just beginning to expand, with many studies being presented at international meetings. For anterior and, possibly, apical vaginal prolapse, the cure rate after use of a mesh kit appears to be as high as, or higher than, the rate for sutured repairs.4 This high rate of anatomic cure is balanced somewhat by additional cost and complications involving mesh and the kits.
For posterior vaginal wall prolapse and rectocele, I firmly believe, based on our research and that of others, that sutured repairs are superior to graft-augmented surgery.5
DR. KARRAM: What are the indications and contraindications for mesh augmentation of prolapse repair ( FIGURES 1 and 2 )?
DR. LUCENTE: I believe mesh is indicated in any patient in need of surgical repair of pelvic organ prolapse who is seeking optimal durability and is willing to accept the known risks of the surgery.
The issue becomes more complex when it comes to contraindications. Absolute contraindications are fairly obvious; they include medically unstable patients and those who may have an inactive infectious process within the pelvis or even undiagnosed abnormal uterine bleeding.
At our center, because the potential for dyspareunia and pelvic discomfort is our biggest concern, we have developed a profile of the patient who is more likely to develop these complaints. The profile includes any patient who has a chronic pain disorder of any type, but especially chronic pelvic pain disorders such as endometriosis and vulvodynia. Other risk factors appear to be a history of pelvic surgery involving any permanent material, suture or mesh, and young age.
So if we have a patient in her late 30s who has undergone reconstructive surgery using permanent sutures and who has an element of chronic pelvic pain, we would counsel her strongly to consider surgical options other than the use of synthetic mesh.
DR. WALTERS: The main indications for mesh-augmented prolapse repair are recurrent posthysterectomy vaginal vault prolapse, for which I usually perform ASC, and recurrent cystocele or anteriorapical prolapse, for which I use one of the anterior mesh kits.
I still think sutured repairs—by that, I mean uterosacral ligament or sacrospinous colpopexy with sutured rectocele repair—work best for recurrent posterior wall and posteriorapical prolapse. I don’t use mesh augmentation for rectocele.
The main contraindication to mesh augmentation, as I see it, is a history of mesh complications. If I am repairing a mesh complication such as erosion or pain, I do not place another mesh.
Medical issues that might increase mesh complications, such as diabetes, steroid use, or severe vaginal atrophy, would, at the very least, make me consider carefully whether mesh augmentation is appropriate. The literature is not clear on this, so mesh could still be used if the surgeon thinks it is necessary.
DR. KARRAM: I haven’t found a definitive indication for mesh augmentation. We have used biologic meshes empirically, but I am not convinced that they really add long-term durability, regardless of whether they are used in the anterior or posterior vaginal segment.
Our published durability rate for traditional suture-type repairs is in the range of 85% at 5 years out.6 Even if I assumed that mesh would give me 100% 5-year durability, this rate would have to be at the expense of some erosion, pain, and other complications unique to mesh. I do not think that the potential improvement in durability is worth these potential complications.
FIGURE 1 When the pelvic support system is intact, prolapse is rare
In the normal pelvis, organs are supported by a complex web of muscles, fascia, and connective tissue.
FIGURE 2 Mesh augmentation seeks to enhance the durability of repair
One type of mesh in final position. Mesh-augmented repair restores the vaginal apex and lends support to the walls of the vagina.
DR. KARRAM: If you are doing a lot of mesh repairs, you are obviously content with the results and feel that the few complications you are seeing are outweighed by the advantages mesh confers. How do you avoid extrusion and avert creation of a painful vagina?
DR. RAZ: Most of our cases are recurrent prolapse after failed vaginal or abdominal repair. I am indeed using a significant amount of soft polypropylene mesh for reconstructive procedures. As with the use of any other synthetic material, low-grade infection can develop after a few weeks or months. I use copious irrigation with antibiotic solution during reconstruction.
To avoid extrusion, I perform deep, rather than superficial, dissection of the vaginal wall to allow for better coverage of the mesh. For posterior mesh reconstruction, I cover the mesh with pararectal fascia to prevent erosion.
For mesh-augmented procedures, I cut the mesh myself in the operating room ( FIGURE 3 ). For a sling, I use a 10 cm × 1 cm soft polypropylene mesh. For a grade 3 or 4 cystocele, I use a trapezoid of soft polypropylene mesh with several points of fixation:
- at the sacrouterine ligament
- lateral to the obturator fascia
- distal to the bladder neck.
I always repair the vault at the same time.
For vault prolapse, I use a segment of soft polypropylene mesh in the shape of an apron with two arms (1 cm × 4 cm) and a central segment (4 cm × 7 cm). I support the vault using number 1-0 delayed absorbable suture and mesh. From outside the vaginal wall, in the posterolateral deep vaginal wall (inside the peritoneum), I incorporate the origin of the sacrouterine ligament and one arm of the mesh in the groove between the colon and levator ani, 15 cm from the introitus. I bring the suture 1 cm from the original entrance. A separate set of sutures brings the perirectal fascia together with the sacrouterine ligaments and perivesical fascia to close the peritoneal cavity. I tie the vault-suspension sutures, providing support to the cuff in a high posterior position (12 to 15 cm from the introitus).
In selected cases of significant recurrent rectocele, I use a rectangle of soft polypropylene mesh anchored to the origin of the sacrouterine ligament and distal to the perineal membrane. The mesh is covered by the pararectal fascia.
We have not seen vaginal, urethral, or bladder erosion in 1,800 cases of our distal urethral Prolene sling procedure using 10 cm × 1 cm soft mesh. In patients who have significant cystocele, vault prolapse, and recurrent rectocele, our vaginal erosion rate is 3%. We have never encountered rectal, bladder, or bowel perforation using our technique.
DR. LUCENTE: We often use mesh and are more than simply content with our results—we are extremely pleased, and so are our patients. Having said that, our techniques have definitely evolved over the past few years, as we’ve focused on how to decrease exposure and, more recently, optimize sexual function and vaginal comfort.
First, to avoid exposure, the most critical step is precise hydrodissection and distention of the true vesicovaginal space. This step can only be achieved through careful tactile guidance of the needle tip into the space, where it should remain while hydrodissection is performed. Always remember, sharp dissection “follows” hydrodissection. If you place the needle bevel within the vaginal wall, you will “split” the vaginal wall—as during standard colporrhaphy—which will lead to a high exposure rate.
Second, to avoid dyspareunia, it’s essential to pay close attention to POP-Q measurements, especially vaginal length, to ensure that the reconstruction restores the same length without foreshortening. This approach entails leaving the cervix in most patients who have a shorter vagina, and making sure that the mesh is secured above the ischial spine in younger, sexually active patients who have demonstrated a higher risk of postoperative deep, penetrating dyspareunia, compared with older, less sexually active patients.
Also paramount is to ensure that you have manually displaced the vagina inwardly as much as possible before deploying or setting the mesh. If you simply try to suture secure the mesh with the vagina incised open, without the ability to deploy the mesh with a closed, displaced vagina (to mimic deep penetration), it is difficult, if not impossible, to properly set the mesh for optimal comfort.
In the early days of midurethral pubovaginal slings using polypropylene, the adage was “looser is better than tighter.” This is even truer for transvaginal mesh.
DR. KARRAM: Dr. Walters, please describe your current surgical procedure of choice without mesh and explain why you haven’t adopted mesh for routine repairs.
DR. WALTERS: About 20% of my prolapse surgeries—usually for posthysterectomy or recurrent vaginal vault prolapse—involve ASC with placement of polypropylene mesh. I perform most of these cases through a Pfannenstiel incision, but I’ve also done them laparoscopically. Several of my partners perform ASC laparoscopically and robotically.
For the other 80% of my patients who have prolapse, I perform repairs transvaginally, usually using high bilateral uterosacralligament vaginal-vault suspension. We have learned to suture higher and slightly more medial on the uterosacral ligaments to attain greater vaginal depth and minimize ureteral obstruction. We use two or three sutures on each uterosacral ligament, usually a combination of permanent and delayed absorbable sutures.
I am also performing more sacrospinous ligament suspensions because this operation is being studied by the Pelvic Floor Disorders Network. Properly performed, it is an excellent surgery for apical prolapse. But, as with most of our surgeries for prolapse, recurrent anterior wall prolapse remains a problem.
Like you, Dr. Karram, we’ve studied our group’s anatomic and functional outcomes very carefully for more than 10 years and are mostly satisfied with our cure and complication rates. Although our anatomic outcomes with these surgeries are not always perfect, our reoperation rate for prolapse is only about 5%, with a high level of satisfaction in 88% to 92% of patients.
DR. RAZ: Unaugmented reconstruction fails in more than 30% of cases. Some patients who have significant prolapse and attenuated tissue think that this tissue will become healthier or stronger after reconstructive surgery, but that isn’t the case. In these situations, excision and plication make no clinical sense.
The problem is that we have yet to identify the ideal surrogate for poor-quality tissue. Most of us use polypropylene mesh in different variations. We need a better material that will be nonimmunogenic, well tolerated, and easily incorporated without erosion. Xenograft-like derivatives of dermis, or allografts such as cadaveric fascia, have failed over the long term because the body reabsorbs the graft without forming any new connective tissue.

Is a kit a valuable aid?
DR. KARRAM: If a surgeon wants to augment a repair, what are the advantages of a packaged mesh kit, compared with simply cutting the mesh and performing surgery without a kit?
DR. WALTERS: The advantages of a packaged mesh kit are the convenience involved and the ability to consistently perform the same operation with the same product. That facilitates learning, teaching, and research. It also helps us understand the published literature a little better because “custom” prolapse repairs are operator-dependent and difficult to apply generally to a population of surgeons.
These advantages are most clearly apparent with midurethral sling mesh kits, which have almost revolutionized surgery for stress incontinence. I don’t believe mesh kits for prolapse are there yet, but they certainly have potential.
DR. RAZ: I’m opposed to the use of kits. They are industry-driven. One company has made $1 billion selling them. Imagine a patient who undergoes placement of a sling kit ($1,000), cystocele kit ($1,500), and posterior mesh kit ($1,500). How can our healthcare system sustain this burden, especially when there is no real evidence that a kit improves the operation, and given the incredible complication rate that we see?
Moreover, the kits contain a single-use needle and passer and a precut segment of polypropylene mesh. But every patient is different and requires a unique size or shape of mesh. I don’t believe that a surgeon who knows pelvic anatomy needs a kit to perform mesh-augmented reconstruction. We can buy the same segment of mesh for $200 to $400, cut it as needed, and perform the same operation advertised by industry.
For surgeons who prefer a kit, the tools that are included should be made reusable.
DR. LUCENTE: In my opinion, the primary advantage of a commercially available transvaginal mesh delivery system—notice, I avoided the word “kit,” because I think there are plenty of negative connotations associated with it—is the ability to deliver the mesh in a “tension”-free manner.
One alternative that many people pursue is cutting the mesh to size and using sutures to hold it in place while tissue ingrowth occurs. However, the hernia literature suggests that suturing mesh in place increases the risk of postoperative discomfort at the site of implantation. The true cause of the discomfort remains unclear, but it is thought to arise from nerve tethering or traction at the pre-committed points of attachment before the host tissue and mesh interface have adjusted or settled with tissue ingrowth.
All neuropathic complications of mesh implantation have been shown in the current hernia literature to be increased with the use of sutures.7 Also, as previously mentioned, it is extremely difficult to set or adjust the mesh with the vaginal incision remaining “open,” which is a downside to suture techniques.
What training is necessary to use a kit?
DR. KARRAM: Mesh kits are aggressively promoted by industry, with close to half a dozen different kits to be available soon. What is the minimum amount of training one should have before utilizing these kits?
DR. WALTERS: The surgeon should at least know how to perform traditional sutured prolapse repairs and SUI surgery and be able to perform cystoscopy. Ideally, the surgeon should undergo training on a cadaver with a skilled and experienced user of the mesh kit. The surgeon also should carefully review the risks and benefits of mesh kits with the patient and inform the patient that he or she is in the early learning curve of a particular surgery. The informed patient should have a right to refuse mesh-augmented prolapse surgery after the consent process.
DR. LUCENTE: I’m glad you asked this question. I strongly believe that surgical expertise and proficiency within gynecology need to be more effectively addressed by us all. We have a situation in our field in which techniques and technology are widening the gap between what is possible and what the surgeon is comfortable doing safely.
It’s incumbent on all of us, especially those who are in a leadership position as a chairperson or chief of a division, to work with our physician staff and faculty to optimize surgical skill and patient outcomes, including safety, with new technologies.
As for the minimal amount of training needed, that’s extremely variable. It depends on the current skill set of the physician and his or her ability to pick up the mechanics of the surgery as it is taught through a cadaver lab or preceptorship. It’s regrettable that some physicians lack the objectivity and insight to judge their own skill set. This, again, is the time for a chairperson or chief of a division to step up to the plate and ensure proper credentialing and demonstration of proficiency.
It is unrealistic to expect industry to decide who should or should not utilize this truly breakthrough technology. That is our responsibility as physicians.
DR. KARRAM: At a minimum, I think any surgeon utilizing a kit should have a firm understanding of pelvic floor anatomy and experience performing traditional repairs:
- intraperitoneal procedures such as Mc-Call culdoplasty and uterosacral suspension
- sacrospinous suspension
- retropubic procedures and anti-incontinence operations such as pubovaginal slings.
This three-dimensional understanding of the pelvic floor is mandatory if one is to assume that blind passage of trocars through potentially dangerous spaces is the wave of the future.
DR. RAZ: You need to be a pelvic surgeon, know your anatomy, and know how to manage complications if you are going to use one of these kits. You should stick to the surgery that works best in your hands. Industry cannot teach you to be a good pelvic surgeon; it takes lifelong experience.
DR. KARRAM: If you have a patient who is sexually inactive with pelvic organ prolapse, would you prefer a mesh repair or an obliterative procedure? And why?
DR. WALTERS: If the patient is sexually inactive—especially if she is older and definitely will not be in the future—it makes absolutely no sense to perform a mesh-augmented repair. A traditional, somewhat tight, sutured repair works fine in this setting and carries very low risk.
In fact, our group and others have found that, in carefully selected patients, partial colpectomy and colpocleisis procedures (without grafts) have among the highest cure and satisfaction rates of all surgeries we perform for prolapse; they also have relatively low risk.8 Recurrent prolapse after an obliterative procedure is rare; most of the dissatisfaction relates to postoperative voiding difficulties or persistent or de novo urinary incontinence.
DR. KARRAM: I also prefer an obliterative procedure. I see no reason to bring in the cost and potential for complications that mesh repair entails. An obliterative procedure should produce an anatomic success rate close to 100%, with minimal complications. It also can be performed quickly with minimal anesthesia and convalescence.
DR. LUCENTE: My response is based on a clinical study that my associate, Dr. Miles Murphy, has performed, comparing a transvaginal mesh procedure with a LaForte operation for severe pelvic organ prolapse.9 Both patient groups were well satisfied with the result, and success rates were comparable. However, the group that underwent the transvaginal mesh procedure had a shorter operative time.
As a result of these studies, we tend to prefer transvaginal mesh repair. Even though the woman may be sexually inactive, the procedure preserves vaginal function, and we all know that life has a way of being unpredictable. Her situation may change so that she once again desires sexual function.
However, for a very elderly woman—one in her late 80s or 90s—who has severe or extreme prolapse with a very large procidentia and vaginal length measuring, say, 13 cm beyond the introitus, I do prefer an obliterative procedure.
DR. RAZ: I agree. I would not offer a sexually inactive patient an obliterative procedure. You never know what the future will hold.
Mesh repair can be performed safely, provided the surgeon has good knowledge of anatomic landmarks and knows how to manage any potential complications that may arise.

Mesh kits for repairing prolapse are proliferating like crazy, just as they did for midurethral sling procedures. But mesh augmentation of prolapse surgeries requires more than a prepackaged assortment of tools and materials. In this article, moderator Mickey M. Karram, MD, and a panel of nationally recognized urogynecologists and urologists describe the literature on mesh augmentation and discuss indications, contraindications, techniques, applicable cases, and the considerable training required.
In Part 2, which will appear in the February issue of OBG Management, the panel tackles the thorny topic of complications, including erosion, extrusion, foreshortening of the vagina, dyspareunia, and pain. Their discussion focuses on ways to avoid these problems, and methods for correcting them.
Do we have enough data?
DR. KARRAM: To start, let’s quickly review the peer-reviewed literature on the use of mesh augmentation during surgery for pelvic organ prolapse.
DR. WALTERS: Until recently, most data concerned open abdominal sacrocolpopexy (ASC) using polypropylene or Merseline mesh. There is significant clinical experience with this operation, and multiple cohort studies show long-term cure rates of 78% to 100% for apical prolapse.1
At least two randomized controlled trials have compared open ASC with sutured vaginal colpopexy procedures, and ASC is certainly equal to—perhaps better than—all transvaginal sutured repairs.2,3
With ASC, most recurrences affect the distal half of the vagina and involve one or more of the following:
- anterior or posterior vaginal wall prolapse (or both)
- stress urinary incontinence (SUI)
- distal rectocele.1,3
Mesh erosion occurs in 3.4% of cases and is usually easily managed.1 Other complications, including bowel injury, tend to be related to access, regardless of whether the operation is performed via laparotomy or laparoscopy.
Robotic sacrocolpopexy has become popular in recent years, and we will probably see data on this approach as we gain experience.
When it comes to vaginal mesh kits, the peer-reviewed literature is just beginning to expand, with many studies being presented at international meetings. For anterior and, possibly, apical vaginal prolapse, the cure rate after use of a mesh kit appears to be as high as, or higher than, the rate for sutured repairs.4 This high rate of anatomic cure is balanced somewhat by additional cost and complications involving mesh and the kits.
For posterior vaginal wall prolapse and rectocele, I firmly believe, based on our research and that of others, that sutured repairs are superior to graft-augmented surgery.5
DR. KARRAM: What are the indications and contraindications for mesh augmentation of prolapse repair ( FIGURES 1 and 2 )?
DR. LUCENTE: I believe mesh is indicated in any patient in need of surgical repair of pelvic organ prolapse who is seeking optimal durability and is willing to accept the known risks of the surgery.
The issue becomes more complex when it comes to contraindications. Absolute contraindications are fairly obvious; they include medically unstable patients and those who may have an inactive infectious process within the pelvis or even undiagnosed abnormal uterine bleeding.
At our center, because the potential for dyspareunia and pelvic discomfort is our biggest concern, we have developed a profile of the patient who is more likely to develop these complaints. The profile includes any patient who has a chronic pain disorder of any type, but especially chronic pelvic pain disorders such as endometriosis and vulvodynia. Other risk factors appear to be a history of pelvic surgery involving any permanent material, suture or mesh, and young age.
So if we have a patient in her late 30s who has undergone reconstructive surgery using permanent sutures and who has an element of chronic pelvic pain, we would counsel her strongly to consider surgical options other than the use of synthetic mesh.
DR. WALTERS: The main indications for mesh-augmented prolapse repair are recurrent posthysterectomy vaginal vault prolapse, for which I usually perform ASC, and recurrent cystocele or anteriorapical prolapse, for which I use one of the anterior mesh kits.
I still think sutured repairs—by that, I mean uterosacral ligament or sacrospinous colpopexy with sutured rectocele repair—work best for recurrent posterior wall and posteriorapical prolapse. I don’t use mesh augmentation for rectocele.
The main contraindication to mesh augmentation, as I see it, is a history of mesh complications. If I am repairing a mesh complication such as erosion or pain, I do not place another mesh.
Medical issues that might increase mesh complications, such as diabetes, steroid use, or severe vaginal atrophy, would, at the very least, make me consider carefully whether mesh augmentation is appropriate. The literature is not clear on this, so mesh could still be used if the surgeon thinks it is necessary.
DR. KARRAM: I haven’t found a definitive indication for mesh augmentation. We have used biologic meshes empirically, but I am not convinced that they really add long-term durability, regardless of whether they are used in the anterior or posterior vaginal segment.
Our published durability rate for traditional suture-type repairs is in the range of 85% at 5 years out.6 Even if I assumed that mesh would give me 100% 5-year durability, this rate would have to be at the expense of some erosion, pain, and other complications unique to mesh. I do not think that the potential improvement in durability is worth these potential complications.

FIGURE 2 Mesh augmentation seeks to enhance the durability of repair
One type of mesh in final position. Mesh-augmented repair restores the vaginal apex and lends support to the walls of the vagina.
DR. KARRAM: If you are doing a lot of mesh repairs, you are obviously content with the results and feel that the few complications you are seeing are outweighed by the advantages mesh confers. How do you avoid extrusion and avert creation of a painful vagina?
DR. RAZ: Most of our cases are recurrent prolapse after failed vaginal or abdominal repair. I am indeed using a significant amount of soft polypropylene mesh for reconstructive procedures. As with the use of any other synthetic material, low-grade infection can develop after a few weeks or months. I use copious irrigation with antibiotic solution during reconstruction.
To avoid extrusion, I perform deep, rather than superficial, dissection of the vaginal wall to allow for better coverage of the mesh. For posterior mesh reconstruction, I cover the mesh with pararectal fascia to prevent erosion.
For mesh-augmented procedures, I cut the mesh myself in the operating room ( FIGURE 3 ). For a sling, I use a 10 cm × 1 cm soft polypropylene mesh. For a grade 3 or 4 cystocele, I use a trapezoid of soft polypropylene mesh with several points of fixation:
- at the sacrouterine ligament
- lateral to the obturator fascia
- distal to the bladder neck.
I always repair the vault at the same time.
For vault prolapse, I use a segment of soft polypropylene mesh in the shape of an apron with two arms (1 cm × 4 cm) and a central segment (4 cm × 7 cm). I support the vault using number 1-0 delayed absorbable suture and mesh. From outside the vaginal wall, in the posterolateral deep vaginal wall (inside the peritoneum), I incorporate the origin of the sacrouterine ligament and one arm of the mesh in the groove between the colon and levator ani, 15 cm from the introitus. I bring the suture 1 cm from the original entrance. A separate set of sutures brings the perirectal fascia together with the sacrouterine ligaments and perivesical fascia to close the peritoneal cavity. I tie the vault-suspension sutures, providing support to the cuff in a high posterior position (12 to 15 cm from the introitus).
In selected cases of significant recurrent rectocele, I use a rectangle of soft polypropylene mesh anchored to the origin of the sacrouterine ligament and distal to the perineal membrane. The mesh is covered by the pararectal fascia.
We have not seen vaginal, urethral, or bladder erosion in 1,800 cases of our distal urethral Prolene sling procedure using 10 cm × 1 cm soft mesh. In patients who have significant cystocele, vault prolapse, and recurrent rectocele, our vaginal erosion rate is 3%. We have never encountered rectal, bladder, or bowel perforation using our technique.
DR. LUCENTE: We often use mesh and are more than simply content with our results—we are extremely pleased, and so are our patients. Having said that, our techniques have definitely evolved over the past few years, as we’ve focused on how to decrease exposure and, more recently, optimize sexual function and vaginal comfort.
First, to avoid exposure, the most critical step is precise hydrodissection and distention of the true vesicovaginal space. This step can only be achieved through careful tactile guidance of the needle tip into the space, where it should remain while hydrodissection is performed. Always remember, sharp dissection “follows” hydrodissection. If you place the needle bevel within the vaginal wall, you will “split” the vaginal wall—as during standard colporrhaphy—which will lead to a high exposure rate.
Second, to avoid dyspareunia, it’s essential to pay close attention to POP-Q measurements, especially vaginal length, to ensure that the reconstruction restores the same length without foreshortening. This approach entails leaving the cervix in most patients who have a shorter vagina, and making sure that the mesh is secured above the ischial spine in younger, sexually active patients who have demonstrated a higher risk of postoperative deep, penetrating dyspareunia, compared with older, less sexually active patients.
Also paramount is to ensure that you have manually displaced the vagina inwardly as much as possible before deploying or setting the mesh. If you simply try to suture secure the mesh with the vagina incised open, without the ability to deploy the mesh with a closed, displaced vagina (to mimic deep penetration), it is difficult, if not impossible, to properly set the mesh for optimal comfort.
In the early days of midurethral pubovaginal slings using polypropylene, the adage was “looser is better than tighter.” This is even truer for transvaginal mesh.
DR. KARRAM: Dr. Walters, please describe your current surgical procedure of choice without mesh and explain why you haven’t adopted mesh for routine repairs.
DR. WALTERS: About 20% of my prolapse surgeries—usually for posthysterectomy or recurrent vaginal vault prolapse—involve ASC with placement of polypropylene mesh. I perform most of these cases through a Pfannenstiel incision, but I’ve also done them laparoscopically. Several of my partners perform ASC laparoscopically and robotically.
For the other 80% of my patients who have prolapse, I perform repairs transvaginally, usually using high bilateral uterosacralligament vaginal-vault suspension. We have learned to suture higher and slightly more medial on the uterosacral ligaments to attain greater vaginal depth and minimize ureteral obstruction. We use two or three sutures on each uterosacral ligament, usually a combination of permanent and delayed absorbable sutures.
I am also performing more sacrospinous ligament suspensions because this operation is being studied by the Pelvic Floor Disorders Network. Properly performed, it is an excellent surgery for apical prolapse. But, as with most of our surgeries for prolapse, recurrent anterior wall prolapse remains a problem.
Like you, Dr. Karram, we’ve studied our group’s anatomic and functional outcomes very carefully for more than 10 years and are mostly satisfied with our cure and complication rates. Although our anatomic outcomes with these surgeries are not always perfect, our reoperation rate for prolapse is only about 5%, with a high level of satisfaction in 88% to 92% of patients.
DR. RAZ: Unaugmented reconstruction fails in more than 30% of cases. Some patients who have significant prolapse and attenuated tissue think that this tissue will become healthier or stronger after reconstructive surgery, but that isn’t the case. In these situations, excision and plication make no clinical sense.
The problem is that we have yet to identify the ideal surrogate for poor-quality tissue. Most of us use polypropylene mesh in different variations. We need a better material that will be nonimmunogenic, well tolerated, and easily incorporated without erosion. Xenograft-like derivatives of dermis, or allografts such as cadaveric fascia, have failed over the long term because the body reabsorbs the graft without forming any new connective tissue.

Is a kit a valuable aid?
DR. KARRAM: If a surgeon wants to augment a repair, what are the advantages of a packaged mesh kit, compared with simply cutting the mesh and performing surgery without a kit?
DR. WALTERS: The advantages of a packaged mesh kit are the convenience involved and the ability to consistently perform the same operation with the same product. That facilitates learning, teaching, and research. It also helps us understand the published literature a little better because “custom” prolapse repairs are operator-dependent and difficult to apply generally to a population of surgeons.
These advantages are most clearly apparent with midurethral sling mesh kits, which have almost revolutionized surgery for stress incontinence. I don’t believe mesh kits for prolapse are there yet, but they certainly have potential.
DR. RAZ: I’m opposed to the use of kits. They are industry-driven. One company has made $1 billion selling them. Imagine a patient who undergoes placement of a sling kit ($1,000), cystocele kit ($1,500), and posterior mesh kit ($1,500). How can our healthcare system sustain this burden, especially when there is no real evidence that a kit improves the operation, and given the incredible complication rate that we see?
Moreover, the kits contain a single-use needle and passer and a precut segment of polypropylene mesh. But every patient is different and requires a unique size or shape of mesh. I don’t believe that a surgeon who knows pelvic anatomy needs a kit to perform mesh-augmented reconstruction. We can buy the same segment of mesh for $200 to $400, cut it as needed, and perform the same operation advertised by industry.
For surgeons who prefer a kit, the tools that are included should be made reusable.
DR. LUCENTE: In my opinion, the primary advantage of a commercially available transvaginal mesh delivery system—notice, I avoided the word “kit,” because I think there are plenty of negative connotations associated with it—is the ability to deliver the mesh in a “tension”-free manner.
One alternative that many people pursue is cutting the mesh to size and using sutures to hold it in place while tissue ingrowth occurs. However, the hernia literature suggests that suturing mesh in place increases the risk of postoperative discomfort at the site of implantation. The true cause of the discomfort remains unclear, but it is thought to arise from nerve tethering or traction at the pre-committed points of attachment before the host tissue and mesh interface have adjusted or settled with tissue ingrowth.
All neuropathic complications of mesh implantation have been shown in the current hernia literature to be increased with the use of sutures.7 Also, as previously mentioned, it is extremely difficult to set or adjust the mesh with the vaginal incision remaining “open,” which is a downside to suture techniques.
What training is necessary to use a kit?
DR. KARRAM: Mesh kits are aggressively promoted by industry, with close to half a dozen different kits to be available soon. What is the minimum amount of training one should have before utilizing these kits?
DR. WALTERS: The surgeon should at least know how to perform traditional sutured prolapse repairs and SUI surgery and be able to perform cystoscopy. Ideally, the surgeon should undergo training on a cadaver with a skilled and experienced user of the mesh kit. The surgeon also should carefully review the risks and benefits of mesh kits with the patient and inform the patient that he or she is in the early learning curve of a particular surgery. The informed patient should have a right to refuse mesh-augmented prolapse surgery after the consent process.
DR. LUCENTE: I’m glad you asked this question. I strongly believe that surgical expertise and proficiency within gynecology need to be more effectively addressed by us all. We have a situation in our field in which techniques and technology are widening the gap between what is possible and what the surgeon is comfortable doing safely.
It’s incumbent on all of us, especially those who are in a leadership position as a chairperson or chief of a division, to work with our physician staff and faculty to optimize surgical skill and patient outcomes, including safety, with new technologies.
As for the minimal amount of training needed, that’s extremely variable. It depends on the current skill set of the physician and his or her ability to pick up the mechanics of the surgery as it is taught through a cadaver lab or preceptorship. It’s regrettable that some physicians lack the objectivity and insight to judge their own skill set. This, again, is the time for a chairperson or chief of a division to step up to the plate and ensure proper credentialing and demonstration of proficiency.
It is unrealistic to expect industry to decide who should or should not utilize this truly breakthrough technology. That is our responsibility as physicians.
DR. KARRAM: At a minimum, I think any surgeon utilizing a kit should have a firm understanding of pelvic floor anatomy and experience performing traditional repairs:
- intraperitoneal procedures such as Mc-Call culdoplasty and uterosacral suspension
- sacrospinous suspension
- retropubic procedures and anti-incontinence operations such as pubovaginal slings.
This three-dimensional understanding of the pelvic floor is mandatory if one is to assume that blind passage of trocars through potentially dangerous spaces is the wave of the future.
DR. RAZ: You need to be a pelvic surgeon, know your anatomy, and know how to manage complications if you are going to use one of these kits. You should stick to the surgery that works best in your hands. Industry cannot teach you to be a good pelvic surgeon; it takes lifelong experience.
DR. KARRAM: If you have a patient who is sexually inactive with pelvic organ prolapse, would you prefer a mesh repair or an obliterative procedure? And why?
DR. WALTERS: If the patient is sexually inactive—especially if she is older and definitely will not be in the future—it makes absolutely no sense to perform a mesh-augmented repair. A traditional, somewhat tight, sutured repair works fine in this setting and carries very low risk.
In fact, our group and others have found that, in carefully selected patients, partial colpectomy and colpocleisis procedures (without grafts) have among the highest cure and satisfaction rates of all surgeries we perform for prolapse; they also have relatively low risk.8 Recurrent prolapse after an obliterative procedure is rare; most of the dissatisfaction relates to postoperative voiding difficulties or persistent or de novo urinary incontinence.
DR. KARRAM: I also prefer an obliterative procedure. I see no reason to bring in the cost and potential for complications that mesh repair entails. An obliterative procedure should produce an anatomic success rate close to 100%, with minimal complications. It also can be performed quickly with minimal anesthesia and convalescence.
DR. LUCENTE: My response is based on a clinical study that my associate, Dr. Miles Murphy, has performed, comparing a transvaginal mesh procedure with a LaForte operation for severe pelvic organ prolapse.9 Both patient groups were well satisfied with the result, and success rates were comparable.

However, for a very elderly woman—one in her late 80s or 90s—who has severe or extreme prolapse with a very large procidentia and vaginal length measuring, say, 13 cm beyond the introitus, I do prefer an obliterative procedure.
DR. RAZ: I agree. I would not offer a sexually inactive patient an obliterative procedure. You never know what the future will hold.
Mesh repair can be performed safely, provided the surgeon has good knowledge of anatomic landmarks and knows how to manage any potential complications that may arise.

This approach entails leaving the cervix in most patients who have a shorter vagina, and making sure that the mesh is secured above the ischial spine in younger, sexually active patients who have demonstrated a higher risk of postoperative deep, penetrating dyspareunia, compared with older, less sexually active patients.
Also paramount is to ensure that you have manually displaced the vagina inwardly as much as possible before deploying or setting the mesh. If you simply try to suture secure the mesh with the vagina incised open, without the ability to deploy the mesh with a closed, displaced vagina (to mimic deep penetration), it is difficult, if not impossible, to properly set the mesh for optimal comfort.
In the early days of midurethral pubovaginal slings using polypropylene, the adage was “looser is better than tighter.” This is even truer for transvaginal mesh.
DR. KARRAM: Dr. Walters, please describe your current surgical procedure of choice without mesh and explain why you haven’t adopted mesh for routine repairs.
DR. WALTERS: About 20% of my prolapse surgeries—usually for posthysterectomy or recurrent vaginal vault prolapse—involve ASC with placement of polypropylene mesh. I perform most of these cases through a Pfannenstiel incision, but I’ve also done them laparoscopically. Several of my partners perform ASC laparoscopically and robotically.
For the other 80% of my patients who have prolapse, I perform repairs transvaginally, usually using high bilateral uterosacralligament vaginal-vault suspension. We have learned to suture higher and slightly more medial on the uterosacral ligaments to attain greater vaginal depth and minimize ureteral obstruction. We use two or three sutures on each uterosacral ligament, usually a combination of permanent and delayed absorbable sutures.
I am also performing more sacrospinous ligament suspensions because this operation is being studied by the Pelvic Floor Disorders Network. Properly performed, it is an excellent surgery for apical prolapse. But, as with most of our surgeries for prolapse, recurrent anterior wall prolapse remains a problem.
Like you, Dr. Karram, we’ve studied our group’s anatomic and functional outcomes very carefully for more than 10 years and are mostly satisfied with our cure and complication rates. Although our anatomic outcomes with these surgeries are not always perfect, our reoperation rate for prolapse is only about 5%, with a high level of satisfaction in 88% to 92% of patients.
DR. RAZ: Unaugmented reconstruction fails in more than 30% of cases. Some patients who have significant prolapse and attenuated tissue think that this tissue will become healthier or stronger after reconstructive surgery, but that isn’t the case. In these situations, excision and plication make no clinical sense.
The problem is that we have yet to identify the ideal surrogate for poor-quality tissue. Most of us use polypropylene mesh in different variations. We need a better material that will be nonimmunogenic, well tolerated, and easily incorporated without erosion. Xenograft-like derivatives of dermis, or allografts such as cadaveric fascia, have failed over the long term because the body reabsorbs the graft without forming any new connective tissue.

Is a kit a valuable aid?
DR. KARRAM: If a surgeon wants to augment a repair, what are the advantages of a packaged mesh kit, compared with simply cutting the mesh and performing surgery without a kit?
DR. WALTERS: The advantages of a packaged mesh kit are the convenience involved and the ability to consistently perform the same operation with the same product. That facilitates learning, teaching, and research. It also helps us understand the published literature a little better because “custom” prolapse repairs are operator-dependent and difficult to apply generally to a population of surgeons.
These advantages are most clearly apparent with midurethral sling mesh kits, which have almost revolutionized surgery for stress incontinence. I don’t believe mesh kits for prolapse are there yet, but they certainly have potential.
DR. RAZ: I’m opposed to the use of kits. They are industry-driven. One company has made $1 billion selling them. Imagine a patient who undergoes placement of a sling kit ($1,000), cystocele kit ($1,500), and posterior mesh kit ($1,500). How can our healthcare system sustain this burden, especially when there is no real evidence that a kit improves the operation, and given the incredible complication rate that we see?
Moreover, the kits contain a single-use needle and passer and a precut segment of polypropylene mesh. But every patient is different and requires a unique size or shape of mesh. I don’t believe that a surgeon who knows pelvic anatomy needs a kit to perform mesh-augmented reconstruction. We can buy the same segment of mesh for $200 to $400, cut it as needed, and perform the same operation advertised by industry.
For surgeons who prefer a kit, the tools that are included should be made reusable.
DR. LUCENTE: In my opinion, the primary advantage of a commercially available transvaginal mesh delivery system—notice, I avoided the word “kit,” because I think there are plenty of negative connotations associated with it—is the ability to deliver the mesh in a “tension”-free manner.
One alternative that many people pursue is cutting the mesh to size and using sutures to hold it in place while tissue ingrowth occurs. However, the hernia literature suggests that suturing mesh in place increases the risk of postoperative discomfort at the site of implantation. The true cause of the discomfort remains unclear, but it is thought to arise from nerve tethering or traction at the pre-committed points of attachment before the host tissue and mesh interface have adjusted or settled with tissue ingrowth.
All neuropathic complications of mesh implantation have been shown in the current hernia literature to be increased with the use of sutures.7 Also, as previously mentioned, it is extremely difficult to set or adjust the mesh with the vaginal incision remaining “open,” which is a downside to suture techniques.
What training is necessary to use a kit?
DR. KARRAM: Mesh kits are aggressively promoted by industry, with close to half a dozen different kits to be available soon. What is the minimum amount of training one should have before utilizing these kits?
DR. WALTERS: The surgeon should at least know how to perform traditional sutured prolapse repairs and SUI surgery and be able to perform cystoscopy. Ideally, the surgeon should undergo training on a cadaver with a skilled and experienced user of the mesh kit. The surgeon also should carefully review the risks and benefits of mesh kits with the patient and inform the patient that he or she is in the early learning curve of a particular surgery. The informed patient should have a right to refuse mesh-augmented prolapse surgery after the consent process.
DR. LUCENTE: I’m glad you asked this question. I strongly believe that surgical expertise and proficiency within gynecology need to be more effectively addressed by us all. We have a situation in our field in which techniques and technology are widening the gap between what is possible and what the surgeon is comfortable doing safely.
It’s incumbent on all of us, especially those who are in a leadership position as a chairperson or chief of a division, to work with our physician staff and faculty to optimize surgical skill and patient outcomes, including safety, with new technologies.
As for the minimal amount of training needed, that’s extremely variable. It depends on the current skill set of the physician and his or her ability to pick up the mechanics of the surgery as it is taught through a cadaver lab or preceptorship. It’s regrettable that some physicians lack the objectivity and insight to judge their own skill set. This, again, is the time for a chairperson or chief of a division to step up to the plate and ensure proper credentialing and demonstration of proficiency.
It is unrealistic to expect industry to decide who should or should not utilize this truly breakthrough technology. That is our responsibility as physicians.
DR. KARRAM: At a minimum, I think any surgeon utilizing a kit should have a firm understanding of pelvic floor anatomy and experience performing traditional repairs:
- intraperitoneal procedures such as Mc-Call culdoplasty and uterosacral suspension
- sacrospinous suspension
- retropubic procedures and anti-incontinence operations such as pubovaginal slings.
This three-dimensional understanding of the pelvic floor is mandatory if one is to assume that blind passage of trocars through potentially dangerous spaces is the wave of the future.
DR. RAZ: You need to be a pelvic surgeon, know your anatomy, and know how to manage complications if you are going to use one of these kits. You should stick to the surgery that works best in your hands. Industry cannot teach you to be a good pelvic surgeon; it takes lifelong experience.
DR. KARRAM: If you have a patient who is sexually inactive with pelvic organ prolapse, would you prefer a mesh repair or an obliterative procedure? And why?
DR. WALTERS: If the patient is sexually inactive—especially if she is older and definitely will not be in the future—it makes absolutely no sense to perform a mesh-augmented repair. A traditional, somewhat tight, sutured repair works fine in this setting and carries very low risk.
In fact, our group and others have found that, in carefully selected patients, partial colpectomy and colpocleisis procedures (without grafts) have among the highest cure and satisfaction rates of all surgeries we perform for prolapse; they also have relatively low risk.8 Recurrent prolapse after an obliterative procedure is rare; most of the dissatisfaction relates to postoperative voiding difficulties or persistent or de novo urinary incontinence.
DR. KARRAM: I also prefer an obliterative procedure. I see no reason to bring in the cost and potential for complications that mesh repair entails. An obliterative procedure should produce an anatomic success rate close to 100%, with minimal complications. It also can be performed quickly with minimal anesthesia and convalescence.
DR. LUCENTE: My response is based on a clinical study that my associate, Dr. Miles Murphy, has performed, comparing a transvaginal mesh procedure with a LaForte operation for severe pelvic organ prolapse.9 Both patient groups were well satisfied with the result, and success rates were comparable. However, the group that underwent the transvaginal mesh procedure had a shorter operative time.
As a result of these studies, we tend to prefer transvaginal mesh repair. Even though the woman may be sexually inactive, the procedure preserves vaginal function, and we all know that life has a way of being unpredictable. Her situation may change so that she once again desires sexual function.
However, for a very elderly woman—one in her late 80s or 90s—who has severe or extreme prolapse with a very large procidentia and vaginal length measuring, say, 13 cm beyond the introitus, I do prefer an obliterative procedure.
DR. RAZ: I agree. I would not offer a sexually inactive patient an obliterative procedure. You never know what the future will hold.
Mesh repair can be performed safely, provided the surgeon has good knowledge of anatomic landmarks and knows how to manage any potential complications that may arise.

6 office tests to assess ovarian reserve, and what they tell you
The University of Medicine and Dentistry of New Jersey (UMDNJ) owns a patent relating to the use of anti-Müllerian hormone/Müllerian inhibiting substance for predicting ovarian response in women with infertility. The patent is based in part on work that Dr. Seifer carried out while employed at UMDNJ. In accordance with UMDNJ policy, Dr. Seifer, a named inventor on this patent, assigned his interest in the invention to UMDNJ. UMDNJ has a licensing agreement with Diagnostic Systems Laboratory for the use of the claimed invention. Dr. Seifer receives a portion of the royalties, as determined by UMDNJ policy, that UMDNJ gains from this licensing agreement.
CASE: Borderline test result prompts referral
A 36-year-old nulliparous woman is seen in your office for evaluation after 6 months of infertility. She is ovulatory, and has been using an ovulation-prediction kit to time intercourse. You learn that she had Chlamydia trachomatis infection in the distant past, but elicit no other significant medical or surgical history. She reports that she smoked approximately one pack of cigarettes a day for 15 years but gave up smoking 5 years ago.
You order a hysterosalpingogram, followed by day 3 testing of follicle-stimulating hormone (FSH). The hysterosalpingogram is normal; the FSH level is 7.5 mIU/mL and the estradiol level is 30 pg/mL—both in the normal range.
The patient asks for testing of anti-Müllerian hormone (AMH; also known as Müllerian-inhibiting substance) because she has read that it is a new marker of fertility. The result is 0.5 ng/mL, a borderline value. After reviewing these results, you refer her to a reproductive endocrinologist for further management.
Was the test for AMH indicated? And is this referral appropriate?
The referral is entirely appropriate, even though the patient has not been trying to conceive for a full year. Why? The AMH value suggests that her ovarian reserve is in early decline. She would benefit from evaluation by a subspecialist who can review the entire spectrum of treatments, including aggressive options such as ovulation induction and in vitro fertilization (IVF), to optimize her reproductive success.
This article reviews the various biomarkers available to assess ovarian reserve in women who experience infertility:
- day 3 (basal) FSH
- clomiphene citrate challenge
- gonadotropin-releasing hormone (GnRH) agonist stimulation
- inhibin-B
- antral follicle count (AFC)
- AMH.
The AFC and AMH tend to detect the earliest changes in ovarian reserve, followed, sequentially, by inhibin-B, the clomiphene citrate challenge test (CCCT), and basal FSH.
The tests we describe are used primarily to assess treatment prognosis in infertile women. In time, however, appropriate population screening of ovarian reserve may be feasible to provide many more women with information about their reproductive potential and help them shape their life plan.
What makes a test valuable?
Ovarian reserve describes a woman’s reproductive potential—specifically, the number and quality of oocytes she possesses.1 Biochemical tests of ovarian reserve emerged during the rise of assisted reproductive technologies (ART) in the late 1980s to predict both responsiveness to superovulation drugs and the odds of pregnancy with treatment.
Ideally, a test that assesses ovarian reserve should be affordable, straightforward, rapidly interpretable, and minimally invasive. It also should be able to detect changes that begin early in reproductive life. To be applicable to large populations of reproductive-age women, it should be of use anytime in the menstrual cycle, and should provide reproducible and highly accurate assessment of the reproductive aging process.
Our ability to offer tests that accurately measure ovarian reserve has a significant impact on women at risk of infertility and early menopause and on those who choose to delay childbearing for personal (nonmedical) reasons. These tests have become increasingly relevant because women are choosing to have their first child at a later age than their counterparts did 20 years ago:
- In 1980, 40% of women having their first baby were younger than 25 years, and only 5% were older than 35
- In 2000, 25% of women were younger than 25 when their first child was born, and 15% were older than 35.
Who should be tested?
Ovarian reserve is a complex clinical phenomenon that is influenced by age, genetics, and environmental variables. The decline in a woman’s ovarian reserve over time is irreversible; the trajectory of this decline is fundamental to the odds of fertility with age and the timing of the menopausal transition. At present, the markers used most often in clinical practice have some utility but also suffer from several drawbacks ( TABLE ).
For the general practitioner performing an infertility evaluation, we recommend focusing on the following groups of women for ovarian reserve testing:
- women over 30 years of age
- women with a history of exposure to a confirmed gonadotoxin, i.e., tobacco smoke, chemotherapy, radiation therapy
- women with a strong family history of early menopause or premature ovarian failure
- women who have had extensive ovarian surgery, i.e., cystectomy and unilateral oophorectomy.
Testing tends to have the highest yield in these groups. Women who have abnormal results should be referred to a reproductive endocrinologist for further evaluation and treatment.
The six tests are described below.
TABLE
How six markers of ovarian reserve stack up
Test (year described) | Timing | Intracycle and intercycle variability | Sensitivity (specificity) | Reflects changes in ovarian reserve | Normal levels | Confounders | Out-of-pocket cost |
---|---|---|---|---|---|---|---|
Basal follicle-stimulating hormone (FSH) (1988) | Day 3 of menstrual cycle | Clinically significant | 7%–8% (98%–99%) | Late | • Early follicular phase FSH level <10 mIU/mL • Estradiol level <80 pg/mL | • High estradiol level (decreases) • Oral contraceptive use (decreases) • Pregnancy (decreases) | $125–$150 |
Clomiphene challenge test (1989) | Days 3 and 10 of menstrual cycle | Clinically significant | 25%–40% (98%–99%) | Late | • Day 3 FSH level <10 mIU/mL; day 3 estradiol level <80 pg/mL • Day 10 FSH level <10 mIU/mL | • High day 3 estradiol level (decreases day 3 FSH) • Low day 10 estradiol (increases day 10 FSH) • Oral contraceptive use (decreases) • Pregnancy (decreases) | $550–$600 |
GnRH agonist (1988) | Early follicular phase of menstrual cycle | Clinically significant | 32%–89% (79%–97%) | Late | Variable | • Oral contraceptives (decrease estradiol levels) • Pregnancy (increases estrogens) | $300–$350 |
Inhibin-B (1997) | Early follicular phase of menstrual cycle | Clinically significant | 33%–81% (29%–95%) | Early | Variable in the literature; normal cutoffs range from ≥45–80 pg/mL | • Obesity (decreases) • PCOS (increases) • Exogenous FSH administration (increases) • Oral contraceptive use (decreases) | $150–$200 |
Antral follicle count (1997) | Early follicular phase of menstrual cycle | Clinically significant (includes interobserver variability) | 8%–60% (33%–96%) | Earliest | ≥5–10 total antral follicles | • Oral contraceptive use (decreases) • Polycystic ovary syndrome (PCOS) (increases) | $300–$500 |
Anti–Müllerian hormone/Müllerian-inhibiting substance (2002) | At any time; not cycle-dependent | Minimal | 49%–76% (89%–94%) | Earliest | >0.7 ng/mL | • PCOS (increases) • Obesity (decreases) • Exogenous FSH administration (decreases) | $150–$400 |
1 | Basal FSH—widely used but only moderately informative
Day 3 FSH and the CCCT are the most widely used measures of ovarian reserve in ART practice. The use of early follicular-phase FSH as a marker of ovarian reserve and fertility was proposed 20 years ago with the emergence of IVF.2-4 The test is an indirect assessment of ovarian reserve in that it measures pituitary production of FSH in response to feedback from ovarian hormones. Estradiol and inhibin-B reach a nadir early in the menstrual cycle; measuring FSH on day 3 offers a glimpse of the functioning of the hypothalamic–pituitary–ovarian axis before ovarian hormone levels rise later in the cycle ( FIGURE 1 ).5,6
FIGURE 1 The HPO axis
The FSH level opens a window onto the function of the hypothalamic–pituitary–ovarian axis before ovarian hormone levels rise in the cycle. Women who have normal ovarian reserve have sufficient ovarian hormone production early in the menstrual cycle to maintain FSH levels within the normal range. Conversely, a “monotropic” elevation in FSH—one that is unaccompanied by a rise in luteinizing hormone (LH)—reflects poor hormone production from an aging pool of ovarian follicles and disinhibition of FSH production.5,6
FSH measurements are typically combined with estradiol to enhance the sensitivity of testing ( FIGURE 2, ). Premature elevations of estradiol early in the follicular phase are driven by rising FSH levels in women with declining ovarian reserve. Abnormally elevated estrogen levels then feed back negatively on pituitary production of FSH and mask an elevation that might otherwise reveal diminished ovarian reserve. Measurement of both FSH and estradiol on cycle day 3 may therefore help decrease the incidence of false-negative testing.
Commonly cited criteria for normal ovarian reserve are:
- early follicular phase FSH, <10 mIU/mL
- estradiol, <80 pg/mL1
It is extremely important to note, however, that these are general guidelines and that cutoffs are both laboratory- and practice-specific.
FIGURE 2 Monthly and lifetime variations in estradiol and FSH

2 | Clomiphene citrate—more sensitive than FSH testing
Like basal FSH testing, the CCCT is an indirect assessment of ovarian reserve. Unlike FSH testing, the CCCT is provocative. It involves administration of 100 mg of clomiphene citrate (Clomid) on days 5 through 9 of the menstrual cycle, with FSH and estradiol measured on days 3 and 10. Once clomiphene citrate is administered, FSH and LH levels rise, followed by an increase in estradiol and inhibin. Evidence suggests that the smaller follicular cohorts in women with diminished ovarian reserve produce less inhibin-B and estradiol and, therefore, less negative feedback on clomiphene-induced pituitary FSH release.6,7 The result: persistent elevation of the day 10 FSH value and a positive screen for diminished ovarian reserve.
In some women, day 10 FSH is elevated even after a normal day 3 value. This makes the CCCT more sensitive than basal FSH testing; it can identify women who might go unrecognized if evaluated by day 3 FSH and estradiol levels alone.
More expensive and labor-intensive than the alternatives
Interpretation of the CCCT requires that FSH and estradiol both be assessed on days 3 and 10. An elevated FSH (≥10 mIU/mL) on either day indicates diminished ovarian reserve. As with basal FSH testing, elevated estradiol (≥80 pg/mL) on day 3 is considered abnormal. The day 10 estradiol value of the CCCT reflects whether or not clomiphene citrate was administered appropriately, and should be elevated. However, the significance of the day 10 estradiol level has been debated with respect to its predictive value for pregnancy in infertile populations.8
The addition of day 10 FSH assessment improves the sensitivity of the CCCT over basal FSH measurement, but makes it a more expensive and labor-intensive test ( TABLE ).5,6 The CCCT involves administration of clomiphene citrate, a safe drug (though it can have side effects), and two blood draws instead of one. Nevertheless, both tests are relatively noninvasive, rapid measures of ovarian reserve.
Drawbacks of the tests
Both basal FSH testing and the CCCT are widely used, although support for their ability to predict ovarian reserve in the infertile population has been challenged recently. Newer data demonstrate that these tests are limited in their ability to predict outcome (pregnancy and response to superovulation drugs) in all but a narrow group of patients undergoing IVF. Performance is particularly limited in:
Additional drawbacks of basal FSH testing and the CCCT include:
- significant variability of test results from cycle to cycle (intercycle variability)
- limited time frame within which the tests can be performed (intracycle variability).
The basal FSH test and CCCT have high specificity (98% to 99% for each) as an assessment of reproductive performance in infertile women and generate few false-positive results.5,6 However, the high screen cutoffs that allow for such specificity come at a price: Few women will screen positive, and sensitivity of the tests is low (between 7% and 8% for basal FSH and between 25% and 40% for the CCCT). Such low sensitivity means that many women will not conceive after infertility treatment despite a normal test result.5,11 Overall, the tests are not highly informative for many women who get tested.
Once abnormal, normal results are meaningless
Once an FSH level or the CCCT has ever been abnormal, the patient has diminished ovarian reserve; normal values in subsequent menstrual cycles do not improve the odds of pregnancy with treatment.14 This fact can be a significant source of confusion and frustration for patients.
3 | GnRH agonist stimulation —no better than FSH testing
This test was developed in the search for a very sensitive assessment of ovarian reserve. It was designed to uncover subtle abnormalities in pituitary and ovarian dynamics. It involves administering a gonadotropin-releasing hormone (GnRH) agonist such as leuprolide acetate (Lupron) on day 2 or 3 of the menstrual cycle and measuring pituitary and ovarian hormone responses.5,15
One group of investigators demonstrated a correlation between stimulated estradiol levels and responsiveness during IVF,16 but other studies have shown that the test does not perform significantly better than day 3 FSH in predicting ovarian reserve.17,18
The sensitivity of GnRH agonist testing for pregnancy is moderate (32% to 89%); specificity ranges from 79% to 97%.19
4 | Inhibin-B—not helpful when used alone
This glycoprotein hormone produced by granulosa cells of developing follicles is a direct measure of ovarian reserve when assessed in the early follicular phase of the menstrual cycle.20 Women treated with IVF who have a low inhibin-B level—particularly when using cutoffs below the range of 45–80 pg/mL—have been shown to respond poorly to superovulation and have a lower pregnancy rate than women with high inhibin-B.21,22 One group of investigators demonstrated that women with clinical evidence of diminished ovarian reserve but a normal FSH level also had low inhibin-B production, suggesting that it may be a more sensitive marker than FSH.22
Inhibin-B testing involves a simple blood draw. However, the test has been incorporated into clinical assessment of ovarian reserve only to a limited degree, due to the lack of reliable assays and controversy concerning its prognostic value.23
Because of these limitations, routine testing of serum inhibin-B in isolation of other markers of ovarian reserve is not recommended.
5 | Antral follicle count—good predictor of IVF outcome
Transvaginal ultrasonographic determination of the number of ovarian follicles that measure between 2 mm and 10 mm in diameter in the early follicular phase of the cycle yields the AFC. As a direct marker of the cohort of growing follicles in the early menstrual cycle, the AFC is believed to correlate strongly with the number of primordial follicles present in the ovary and, therefore, ovarian reserve. Total AFCs of less than 5 to 10 are suggestive of diminished ovarian reserve.24,25
In IVF cycles, AFC has proven to be an accurate predictor of number of oocytes retrieved, risk of cycle cancellation, and odds of conception.24,25 Some investigators have even suggested that, compared with other markers of ovarian reserve, AFC is the best independent predictor of outcome in IVF cycles.7,26-27
In a group of normally cycling women with proven fertility, AFC also showed a strong correlation with age, declining slowly until age 37 and more rapidly thereafter.28,29
AFC sensitivity for pregnancy is moderate and varies widely in published reports (8% to 60%), whereas specificity tends to be higher (33% to 96%).19
Drawbacks of AFC
- Because of the need to perform transvaginal ultrasonography, AFC is a more invasive and often more expensive test than hormonal biomarkers
- Accurate assessment of AFC requires an experienced sonographer and can be limited in patients who have had pelvic surgery or uterine fibroids and in those who are obese
- Moderate interobserver and intercycle variability of AFC determinations limits its reproducibility29,30
- As with basal FSH measurement, the intercycle variability of AFC does not correlate well with IVF outcome in individual patients.30
6 | Anti-Müllerian hormone— many advantages
The drawbacks of the tests just described— e.g., intercycle variability, lack of uniform cutoffs, and limited ability to predict IVF outcomes—make the development of more reliable measures of ovarian reserve a priority in reproductive medicine. AMH is a highly promising marker that appears to have many advantages over other tests and may have the greatest power to predict ovarian aging in women of reproductive age.
How it works
AMH is a glycoprotein growth factor and a member of the transforming growth factor-ß superfamily.31 It is primarily produced by the pool of early-growing follicles, which are believed to serve as a proxy for the number of primordial follicles in the ovary. The number of primordial follicles at a given point in time represents the ovarian reserve. AMH levels above 0.7 ng/mL are considered normal; values between 0.3 ng/mL and 0.7 ng/mL are consistent with borderline ovarian reserve, according to 2007 data from Reprosource Corp.
AMH has been studied as a marker of ovarian reserve for 6 years, with multiple reports describing declines in levels with age and with diminishing oocyte numbers. It is undetectable at menopause.32
The age-related decline in AMH is gradual but measurable even in young women, consistently preceding changes in other markers of ovarian reserve such as FSH and inhibin-B.32-35 The longitudinal changes in AMH have been demonstrated in ovulatory premenopausal women and healthy volunteers with proven fertility.33,34 In one series of women followed over a mean of 4 years (ages 25 to 46), AMH testing was superior to day 3 FSH, inhibin-B, and AFC in its ability to predict the onset of cycle irregularity and the menopausal transition.33
Does it predict oocyte quality?
AMH has performed well as a biomarker, comparable in most series to AFC and superior to FSH. AMH levels are strongly correlated with the number of oocytes retrieved during IVF and the odds of cycle cancellation due to poor response35-41 —but does it accurately characterize oocyte quality, the other element of ovarian reserve?
Some reports have shown a strong association between AMH levels and surrogates of oocyte quality, including fertilization, oocyte morphology, embryo quality, and pregnancy and miscarriage rates,36-41 but others have not.42 Some reports demonstrate a relationship between AMH and some but not all surrogate markers of oocyte quality.40
Advantages of AMH
- It demonstrates minimal intracycle variability.32,43-45 Compared with other markers of ovarian reserve, which must be measured early in the follicular phase of the menstrual cycle, AMH can be assessed at random times, making it a more convenient method for patients and physicians
- It demonstrates minimal intercycle variability32,34
- AMH levels are not significantly affected by the hormonal changes of pregnancy, oral contraceptive use, or GnRH treatment, and can be measured in these settings.46,47
Utility of AMH is limited in PCOS and obesity
The ability to use AMH as a marker of ovarian aging in women who have polycystic ovary syndrome (PCOS) and in women who are obese may be limited by the ovulatory dysfunction in these populations. Circulating levels of AMH are higher in women with PCOS than in unaffected women, a finding thought to be indicative of oligo-ovulation and poor follicular development in polycystic ovaries.48-53
In a recent series investigating AMH levels in women with PCOS, AMH and the degree of insulin resistance were positively correlated, and the AMH level was negatively correlated with the number of menses in a year.49 The consistently positive correlation between AMH and PCOS may suggest a future role for this marker as a diagnostic tool.
In obese women who do not have PCOS, AMH production may be lower than in women of normal weight. In a recent series, normally cycling obese women in the later reproductive years were shown to have an AMH level 70% lower than those in women who were not obese.54 These differences have not been well studied in younger obese women.
Which test is best?
AMH may be preferable to the other tests to assess ovarian reserve because it can be measured any time during the menstrual cycle or between cycles. AMH measurement is also useful if a woman is taking oral contraceptives or leuprolide acetate because these medications may confound the results of the other test methods. In addition, AMH may be the earliest indicator of decline in ovarian reproductive function. As such, it may highlight cases that merit a search for other causes of infertility and make it possible to treat them in a timely manner.
Elevated AMH may reveal occult PCOS and warn of significant risk of ovarian hyperstimulation prior to ovulation induction with gonadotrophins, so that the clinician can plan smaller doses.
A normal female is born with 1 million to 2 million oocytes, a number that declines continuously, primarily through the process of follicular atresia. By the onset of puberty, the number of oocytes has declined to approximately 300,000. As a woman enters her late 30s, when the total number of oocytes is approximately 25,000, the pace of oocyte depletion begins to increase, as does the rate of spontaneous miscarriage.1,55,56
The effect of age on fertility is believed to arise from changes in both oocyte number and quality. Multiple investigators have found a greater frequency of cellular abnormalities in oocytes from older women.1,2,5,15,57
Although ovarian reserve declines with age in all women, women of similar ages can have very different degrees of ovarian reserve, and some women who have very poor ovarian reserve may never conceive, despite aggressive fertility treatment.
The biologic basis for differences in ovarian reserve among similar groups of women is not completely understood, but is probably rooted in genetic, lifestyle, and environmental factors that affect granulosa cell and oocyte function. Identifying sensitive biomarkers that can determine ovarian reserve independent of age is critical to predict fertility and age at menopause.5

CASE: Borderline test result prompts referral
A 36-year-old nulliparous woman is seen in your office for evaluation after 6 months of infertility. She is ovulatory, and has been using an ovulation-prediction kit to time intercourse. You learn that she had Chlamydia trachomatis infection in the distant past, but elicit no other significant medical or surgical history. She reports that she smoked approximately one pack of cigarettes a day for 15 years but gave up smoking 5 years ago.
You order a hysterosalpingogram, followed by day 3 testing of follicle-stimulating hormone (FSH). The hysterosalpingogram is normal; the FSH level is 7.5 mIU/mL and the estradiol level is 30 pg/mL—both in the normal range.
The patient asks for testing of anti-Müllerian hormone (AMH; also known as Müllerian-inhibiting substance) because she has read that it is a new marker of fertility. The result is 0.5 ng/mL, a borderline value. After reviewing these results, you refer her to a reproductive endocrinologist for further management.
Was the test for AMH indicated? And is this referral appropriate?
The referral is entirely appropriate, even though the patient has not been trying to conceive for a full year. Why? The AMH value suggests that her ovarian reserve is in early decline. She would benefit from evaluation by a subspecialist who can review the entire spectrum of treatments, including aggressive options such as ovulation induction and in vitro fertilization (IVF), to optimize her reproductive success.
This article reviews the various biomarkers available to assess ovarian reserve in women who experience infertility:
- day 3 (basal) FSH
- clomiphene citrate challenge
- gonadotropin-releasing hormone (GnRH) agonist stimulation
- inhibin-B
- antral follicle count (AFC)
- AMH.
The AFC and AMH tend to detect the earliest changes in ovarian reserve, followed, sequentially, by inhibin-B, the clomiphene citrate challenge test (CCCT), and basal FSH.
The tests we describe are used primarily to assess treatment prognosis in infertile women. In time, however, appropriate population screening of ovarian reserve may be feasible to provide many more women with information about their reproductive potential and help them shape their life plan.
What makes a test valuable?
Ovarian reserve describes a woman’s reproductive potential—specifically, the number and quality of oocytes she possesses.1 Biochemical tests of ovarian reserve emerged during the rise of assisted reproductive technologies (ART) in the late 1980s to predict both responsiveness to superovulation drugs and the odds of pregnancy with treatment.
Ideally, a test that assesses ovarian reserve should be affordable, straightforward, rapidly interpretable, and minimally invasive. It also should be able to detect changes that begin early in reproductive life. To be applicable to large populations of reproductive-age women, it should be of use anytime in the menstrual cycle, and should provide reproducible and highly accurate assessment of the reproductive aging process.
Our ability to offer tests that accurately measure ovarian reserve has a significant impact on women at risk of infertility and early menopause and on those who choose to delay childbearing for personal (nonmedical) reasons. These tests have become increasingly relevant because women are choosing to have their first child at a later age than their counterparts did 20 years ago:
- In 1980, 40% of women having their first baby were younger than 25 years, and only 5% were older than 35
- In 2000, 25% of women were younger than 25 when their first child was born, and 15% were older than 35.
Who should be tested?
Ovarian reserve is a complex clinical phenomenon that is influenced by age, genetics, and environmental variables. The decline in a woman’s ovarian reserve over time is irreversible; the trajectory of this decline is fundamental to the odds of fertility with age and the timing of the menopausal transition. At present, the markers used most often in clinical practice have some utility but also suffer from several drawbacks ( TABLE ).
For the general practitioner performing an infertility evaluation, we recommend focusing on the following groups of women for ovarian reserve testing:
- women over 30 years of age
- women with a history of exposure to a confirmed gonadotoxin, i.e., tobacco smoke, chemotherapy, radiation therapy
- women with a strong family history of early menopause or premature ovarian failure
- women who have had extensive ovarian surgery, i.e., cystectomy and unilateral oophorectomy.
Testing tends to have the highest yield in these groups. Women who have abnormal results should be referred to a reproductive endocrinologist for further evaluation and treatment.
The six tests are described below.

1 | Basal FSH—widely used but only moderately informative
Day 3 FSH and the CCCT are the most widely used measures of ovarian reserve in ART practice. The use of early follicular-phase FSH as a marker of ovarian reserve and fertility was proposed 20 years ago with the emergence of IVF.2-4 The test is an indirect assessment of ovarian reserve in that it measures pituitary production of FSH in response to feedback from ovarian hormones. Estradiol and inhibin-B reach a nadir early in the menstrual cycle; measuring FSH on day 3 offers a glimpse of the functioning of the hypothalamic–pituitary–ovarian axis before ovarian hormone levels rise later in the cycle ( FIGURE 1 ).5,6
FIGURE 1 The HPO axis
The FSH level opens a window onto the function of the hypothalamic–pituitary–ovarian axis before ovarian hormone levels rise in the cycle. Women who have normal ovarian reserve have sufficient ovarian hormone production early in the menstrual cycle to maintain FSH levels within the normal range. Conversely, a “monotropic” elevation in FSH—one that is unaccompanied by a rise in luteinizing hormone (LH)—reflects poor hormone production from an aging pool of ovarian follicles and disinhibition of FSH production.5,6
FSH measurements are typically combined with estradiol to enhance the sensitivity of testing ( FIGURE 2, ). Premature elevations of estradiol early in the follicular phase are driven by rising FSH levels in women with declining ovarian reserve. Abnormally elevated estrogen levels then feed back negatively on pituitary production of FSH and mask an elevation that might otherwise reveal diminished ovarian reserve. Measurement of both FSH and estradiol on cycle day 3 may therefore help decrease the incidence of false-negative testing.
Commonly cited criteria for normal ovarian reserve are:
- early follicular phase FSH, <10 mIU/mL
- estradiol, <80 pg/mL1
It is extremely important to note, however, that these are general guidelines and that cutoffs are both laboratory- and practice-specific.
FIGURE 2 Monthly and lifetime variations in estradiol and FSH
How 17ß-estradiol and follicle-stimulating hormone levels vary over the menstrual cycle (top) and a woman’s lifetime (bottom).
2 | Clomiphene citrate—more sensitive than FSH testing
Like basal FSH testing, the CCCT is an indirect assessment of ovarian reserve. Unlike FSH testing, the CCCT is provocative. It involves administration of 100 mg of clomiphene citrate (Clomid) on days 5 through 9 of the menstrual cycle, with FSH and estradiol measured on days 3 and 10. Once clomiphene citrate is administered, FSH and LH levels rise, followed by an increase in estradiol and inhibin. Evidence suggests that the smaller follicular cohorts in women with diminished ovarian reserve produce less inhibin-B and estradiol and, therefore, less negative feedback on clomiphene-induced pituitary FSH release.6,7 The result: persistent elevation of the day 10 FSH value and a positive screen for diminished ovarian reserve.
In some women, day 10 FSH is elevated even after a normal day 3 value. This makes the CCCT more sensitive than basal FSH testing; it can identify women who might go unrecognized if evaluated by day 3 FSH and estradiol levels alone.
More expensive and labor-intensive than the alternatives
Interpretation of the CCCT requires that FSH and estradiol both be assessed on days 3 and 10. An elevated FSH (≥10 mIU/mL) on either day indicates diminished ovarian reserve. As with basal FSH testing, elevated estradiol (≥80 pg/mL) on day 3 is considered abnormal. The day 10 estradiol value of the CCCT reflects whether or not clomiphene citrate was administered appropriately, and should be elevated. However, the significance of the day 10 estradiol level has been debated with respect to its predictive value for pregnancy in infertile populations.8
The addition of day 10 FSH assessment improves the sensitivity of the CCCT over basal FSH measurement, but makes it a more expensive and labor-intensive test ( TABLE ).5,6 The CCCT involves administration of clomiphene citrate, a safe drug (though it can have side effects), and two blood draws instead of one. Nevertheless, both tests are relatively noninvasive, rapid measures of ovarian reserve.
Drawbacks of the tests
Both basal FSH testing and the CCCT are widely used, although support for their ability to predict ovarian reserve in the infertile population has been challenged recently. Newer data demonstrate that these tests are limited in their ability to predict outcome (pregnancy and response to superovulation drugs) in all but a narrow group of patients undergoing IVF. Performance is particularly limited in:
Additional drawbacks of basal FSH testing and the CCCT include:
- significant variability of test results from cycle to cycle (intercycle variability)
- limited time frame within which the tests can be performed (intracycle variability).
The basal FSH test and CCCT have high specificity (98% to 99% for each) as an assessment of reproductive performance in infertile women and generate few false-positive results.5,6 However, the high screen cutoffs that allow for such specificity come at a price: Few women will screen positive, and sensitivity of the tests is low (between 7% and 8% for basal FSH and between 25% and 40% for the CCCT). Such low sensitivity means that many women will not conceive after infertility treatment despite a normal test result.5,11 Overall, the tests are not highly informative for many women who get tested.
Once abnormal, normal results are meaningless
Once an FSH level or the CCCT has ever been abnormal, the patient has diminished ovarian reserve; normal values in subsequent menstrual cycles do not improve the odds of pregnancy with treatment.14 This fact can be a significant source of confusion and frustration for patients.
3 | GnRH agonist stimulation —no better than FSH testing
This test was developed in the search for a very sensitive assessment of ovarian reserve. It was designed to uncover subtle abnormalities in pituitary and ovarian dynamics. It involves administering a gonadotropin-releasing hormone (GnRH) agonist such as leuprolide acetate (Lupron) on day 2 or 3 of the menstrual cycle and measuring pituitary and ovarian hormone responses.5,15
One group of investigators demonstrated a correlation between stimulated estradiol levels and responsiveness during IVF,16 but other studies have shown that the test does not perform significantly better than day 3 FSH in predicting ovarian reserve.17,18
The sensitivity of GnRH agonist testing for pregnancy is moderate (32% to 89%); specificity ranges from 79% to 97%.19
4 | Inhibin-B—not helpful when used alone
This glycoprotein hormone produced by granulosa cells of developing follicles is a direct measure of ovarian reserve when assessed in the early follicular phase of the menstrual cycle.20 Women treated with IVF who have a low inhibin-B level—particularly when using cutoffs below the range of 45–80 pg/mL—have been shown to respond poorly to superovulation and have a lower pregnancy rate than women with high inhibin-B.21,22 One group of investigators demonstrated that women with clinical evidence of diminished ovarian reserve but a normal FSH level also had low inhibin-B production, suggesting that it may be a more sensitive marker than FSH.22
Inhibin-B testing involves a simple blood draw. However, the test has been incorporated into clinical assessment of ovarian reserve only to a limited degree, due to the lack of reliable assays and controversy concerning its prognostic value.23
Because of these limitations, routine testing of serum inhibin-B in isolation of other markers of ovarian reserve is not recommended.
5 | Antral follicle count—good predictor of IVF outcome
Transvaginal ultrasonographic determination of the number of ovarian follicles that measure between 2 mm and 10 mm in diameter in the early follicular phase of the cycle yields the AFC. As a direct marker of the cohort of growing follicles in the early menstrual cycle, the AFC is believed to correlate strongly with the number of primordial follicles present in the ovary and, therefore, ovarian reserve. Total AFCs of less than 5 to 10 are suggestive of diminished ovarian reserve.24,25
In IVF cycles, AFC has proven to be an accurate predictor of number of oocytes retrieved, risk of cycle cancellation, and odds of conception.24,25 Some investigators have even suggested that, compared with other markers of ovarian reserve, AFC is the best independent predictor of outcome in IVF cycles.7,26-27
In a group of normally cycling women with proven fertility, AFC also showed a strong correlation with age, declining slowly until age 37 and more rapidly thereafter.28,29
AFC sensitivity for pregnancy is moderate and varies widely in published reports (8% to 60%), whereas specificity tends to be higher (33% to 96%).19
Drawbacks of AFC
- Because of the need to perform transvaginal ultrasonography, AFC is a more invasive and often more expensive test than hormonal biomarkers
- Accurate assessment of AFC requires an experienced sonographer and can be limited in patients who have had pelvic surgery or uterine fibroids and in those who are obese
- Moderate interobserver and intercycle variability of AFC determinations limits its reproducibility29,30
- As with basal FSH measurement, the intercycle variability of AFC does not correlate well with IVF outcome in individual patients.30
6 | Anti-Müllerian hormone— many advantages
The drawbacks of the tests just described— e.g., intercycle variability, lack of uniform cutoffs, and limited ability to predict IVF outcomes—make the development of more reliable measures of ovarian reserve a priority in reproductive medicine. AMH is a highly promising marker that appears to have many advantages over other tests and may have the greatest power to predict ovarian aging in women of reproductive age.
How it works
AMH is a glycoprotein growth factor and a member of the transforming growth factor-ß superfamily.31 It is primarily produced by the pool of early-growing follicles, which are believed to serve as a proxy for the number of primordial follicles in the ovary. The number of primordial follicles at a given point in time represents the ovarian reserve. AMH levels above 0.7 ng/mL are considered normal; values between 0.3 ng/mL and 0.7 ng/mL are consistent with borderline ovarian reserve, according to 2007 data from Reprosource Corp.
AMH has been studied as a marker of ovarian reserve for 6 years, with multiple reports describing declines in levels with age and with diminishing oocyte numbers. It is undetectable at menopause.32
The age-related decline in AMH is gradual but measurable even in young women, consistently preceding changes in other markers of ovarian reserve such as FSH and inhibin-B.32-35 The longitudinal changes in AMH have been demonstrated in ovulatory premenopausal women and healthy volunteers with proven fertility.33,34 In one series of women followed over a mean of 4 years (ages 25 to 46), AMH testing was superior to day 3 FSH, inhibin-B, and AFC in its ability to predict the onset of cycle irregularity and the menopausal transition.33
Does it predict oocyte quality?
AMH has performed well as a biomarker, comparable in most series to AFC and superior to FSH. AMH levels are strongly correlated with the number of oocytes retrieved during IVF and the odds of cycle cancellation due to poor response35-41 —but does it accurately characterize oocyte quality, the other element of ovarian reserve?
Some reports have shown a strong association between AMH levels and surrogates of oocyte quality, including fertilization, oocyte morphology, embryo quality, and pregnancy and miscarriage rates,36-41 but others have not.42 Some reports demonstrate a relationship between AMH and some but not all surrogate markers of oocyte quality.40
Advantages of AMH
- It demonstrates minimal intracycle variability.32,43-45 Compared with other markers of ovarian reserve, which must be measured early in the follicular phase of the menstrual cycle, AMH can be assessed at random times, making it a more convenient method for patients and physicians
- It demonstrates minimal intercycle variability32,34
- AMH levels are not significantly affected by the hormonal changes of pregnancy, oral contraceptive use, or GnRH treatment, and can be measured in these settings.46,47
Utility of AMH is limited in PCOS and obesity
The ability to use AMH as a marker of ovarian aging in women who have polycystic ovary syndrome (PCOS) and in women who are obese may be limited by the ovulatory dysfunction in these populations. Circulating levels of AMH are higher in women with PCOS than in unaffected women, a finding thought to be indicative of oligo-ovulation and poor follicular development in polycystic ovaries.48-53
In a recent series investigating AMH levels in women with PCOS, AMH and the degree of insulin resistance were positively correlated, and the AMH level was negatively correlated with the number of menses in a year.49 The consistently positive correlation between AMH and PCOS may suggest a future role for this marker as a diagnostic tool.
In obese women who do not have PCOS, AMH production may be lower than in women of normal weight. In a recent series, normally cycling obese women in the later reproductive years were shown to have an AMH level 70% lower than those in women who were not obese.54 These differences have not been well studied in younger obese women.
Which test is best?
AMH may be preferable to the other tests to assess ovarian reserve because it can be measured any time during the menstrual cycle or between cycles. AMH measurement is also useful if a woman is taking oral contraceptives or leuprolide acetate because these medications may confound the results of the other test methods. In addition, AMH may be the earliest indicator of decline in ovarian reproductive function. As such, it may highlight cases that merit a search for other causes of infertility and make it possible to treat them in a timely manner.
Elevated AMH may reveal occult PCOS and warn of significant risk of ovarian hyperstimulation prior to ovulation induction with gonadotrophins, so that the clinician can plan smaller doses.
A normal female is born with 1 million to 2 million oocytes, a number that declines continuously, primarily through the process of follicular atresia. By the onset of puberty, the number of oocytes has declined to approximately 300,000. As a woman enters her late 30s, when the total number of oocytes is approximately 25,000, the pace of oocyte depletion begins to increase, as does the rate of spontaneous miscarriage.1,55,56
The effect of age on fertility is believed to arise from changes in both oocyte number and quality. Multiple investigators have found a greater frequency of cellular abnormalities in oocytes from older women.1,2,5,15,57
Although ovarian reserve declines with age in all women, women of similar ages can have very different degrees of ovarian reserve, and some women who have very poor ovarian reserve may never conceive, despite aggressive fertility treatment.
The biologic basis for differences in ovarian reserve among similar groups of women is not completely understood, but is probably rooted in genetic, lifestyle, and environmental factors that affect granulosa cell and oocyte function. Identifying sensitive biomarkers that can determine ovarian reserve independent of age is critical to predict fertility and age at menopause.5

CASE: Borderline test result prompts referral
A 36-year-old nulliparous woman is seen in your office for evaluation after 6 months of infertility. She is ovulatory, and has been using an ovulation-prediction kit to time intercourse. You learn that she had Chlamydia trachomatis infection in the distant past, but elicit no other significant medical or surgical history. She reports that she smoked approximately one pack of cigarettes a day for 15 years but gave up smoking 5 years ago.
You order a hysterosalpingogram, followed by day 3 testing of follicle-stimulating hormone (FSH). The hysterosalpingogram is normal; the FSH level is 7.5 mIU/mL and the estradiol level is 30 pg/mL—both in the normal range.
The patient asks for testing of anti-Müllerian hormone (AMH; also known as Müllerian-inhibiting substance) because she has read that it is a new marker of fertility. The result is 0.5 ng/mL, a borderline value. After reviewing these results, you refer her to a reproductive endocrinologist for further management.
Was the test for AMH indicated? And is this referral appropriate?
The referral is entirely appropriate, even though the patient has not been trying to conceive for a full year. Why? The AMH value suggests that her ovarian reserve is in early decline. She would benefit from evaluation by a subspecialist who can review the entire spectrum of treatments, including aggressive options such as ovulation induction and in vitro fertilization (IVF), to optimize her reproductive success.
This article reviews the various biomarkers available to assess ovarian reserve in women who experience infertility:
- day 3 (basal) FSH
- clomiphene citrate challenge
- gonadotropin-releasing hormone (GnRH) agonist stimulation
- inhibin-B
- antral follicle count (AFC)
- AMH.
The AFC and AMH tend to detect the earliest changes in ovarian reserve, followed, sequentially, by inhibin-B, the clomiphene citrate challenge test (CCCT), and basal FSH.
The tests we describe are used primarily to assess treatment prognosis in infertile women. In time, however, appropriate population screening of ovarian reserve may be feasible to provide many more women with information about their reproductive potential and help them shape their life plan.
What makes a test valuable?
Ovarian reserve describes a woman’s reproductive potential—specifically, the number and quality of oocytes she possesses.1 Biochemical tests of ovarian reserve emerged during the rise of assisted reproductive technologies (ART) in the late 1980s to predict both responsiveness to superovulation drugs and the odds of pregnancy with treatment.
Ideally, a test that assesses ovarian reserve should be affordable, straightforward, rapidly interpretable, and minimally invasive. It also should be able to detect changes that begin early in reproductive life. To be applicable to large populations of reproductive-age women, it should be of use anytime in the menstrual cycle, and should provide reproducible and highly accurate assessment of the reproductive aging process.
Our ability to offer tests that accurately measure ovarian reserve has a significant impact on women at risk of infertility and early menopause and on those who choose to delay childbearing for personal (nonmedical) reasons. These tests have become increasingly relevant because women are choosing to have their first child at a later age than their counterparts did 20 years ago:
- In 1980, 40% of women having their first baby were younger than 25 years, and only 5% were older than 35
- In 2000, 25% of women were younger than 25 when their first child was born, and 15% were older than 35.
Who should be tested?
Ovarian reserve is a complex clinical phenomenon that is influenced by age, genetics, and environmental variables. The decline in a woman’s ovarian reserve over time is irreversible; the trajectory of this decline is fundamental to the odds of fertility with age and the timing of the menopausal transition. At present, the markers used most often in clinical practice have some utility but also suffer from several drawbacks ( TABLE ).
For the general practitioner performing an infertility evaluation, we recommend focusing on the following groups of women for ovarian reserve testing:
- women over 30 years of age
- women with a history of exposure to a confirmed gonadotoxin, i.e., tobacco smoke, chemotherapy, radiation therapy
- women with a strong family history of early menopause or premature ovarian failure
- women who have had extensive ovarian surgery, i.e., cystectomy and unilateral oophorectomy.
Testing tends to have the highest yield in these groups. Women who have abnormal results should be referred to a reproductive endocrinologist for further evaluation and treatment.
The six tests are described below.
TABLE
How six markers of ovarian reserve stack up
Test (year described) | Timing | Intracycle and intercycle variability | Sensitivity (specificity) | Reflects changes in ovarian reserve | Normal levels | Confounders | Out-of-pocket cost |
---|---|---|---|---|---|---|---|
Basal follicle-stimulating hormone (FSH) (1988) | Day 3 of menstrual cycle | Clinically significant | 7%–8% (98%–99%) | Late | • Early follicular phase FSH level <10 mIU/mL • Estradiol level <80 pg/mL | • High estradiol level (decreases) • Oral contraceptive use (decreases) • Pregnancy (decreases) | $125–$150 |

GnRH agonist (1988) | Early follicular phase of menstrual cycle | Clinically significant | 32%–89% (79%–97%) | Late | Variable | • Oral contraceptives (decrease estradiol levels) • Pregnancy (increases estrogens) | $300–$350 |
Inhibin-B (1997) | Early follicular phase of menstrual cycle | Clinically significant | 33%–81% (29%–95%) | Early | Variable in the literature; normal cutoffs range from ≥45–80 pg/mL | • Obesity (decreases) • PCOS (increases) • Exogenous FSH administration (increases) • Oral contraceptive use (decreases) | $150–$200 |
Antral follicle count (1997) | Early follicular phase of menstrual cycle | Clinically significant (includes interobserver variability) | 8%–60% (33%–96%) | Earliest | ≥5–10 total antral follicles | • Oral contraceptive use (decreases) • Polycystic ovary syndrome (PCOS) (increases) | $300–$500 |
Anti–Müllerian hormone/Müllerian-inhibiting substance (2002) | At any time; not cycle-dependent | Minimal | 49%–76% (89%–94%) | Earliest | >0.7 ng/mL | • PCOS (increases) • Obesity (decreases) • Exogenous FSH administration (decreases) | $150–$400 |
1 | Basal FSH—widely used but only moderately informative
Day 3 FSH and the CCCT are the most widely used measures of ovarian reserve in ART practice. The use of early follicular-phase FSH as a marker of ovarian reserve and fertility was proposed 20 years ago with the emergence of IVF.2-4 The test is an indirect assessment of ovarian reserve in that it measures pituitary production of FSH in response to feedback from ovarian hormones. Estradiol and inhibin-B reach a nadir early in the menstrual cycle; measuring FSH on day 3 offers a glimpse of the functioning of the hypothalamic–pituitary–ovarian axis before ovarian hormone levels rise later in the cycle ( FIGURE 1 ).5,6
FIGURE 1 The HPO axis
The FSH level opens a window onto the function of the hypothalamic–pituitary–ovarian axis before ovarian hormone levels rise in the cycle. Women who have normal ovarian reserve have sufficient ovarian hormone production early in the menstrual cycle to maintain FSH levels within the normal range. Conversely, a “monotropic” elevation in FSH—one that is unaccompanied by a rise in luteinizing hormone (LH)—reflects poor hormone production from an aging pool of ovarian follicles and disinhibition of FSH production.5,6
FSH measurements are typically combined with estradiol to enhance the sensitivity of testing ( FIGURE 2, ). Premature elevations of estradiol early in the follicular phase are driven by rising FSH levels in women with declining ovarian reserve. Abnormally elevated estrogen levels then feed back negatively on pituitary production of FSH and mask an elevation that might otherwise reveal diminished ovarian reserve. Measurement of both FSH and estradiol on cycle day 3 may therefore help decrease the incidence of false-negative testing.
Commonly cited criteria for normal ovarian reserve are:
- early follicular phase FSH, <10 mIU/mL
- estradiol, <80 pg/mL1
It is extremely important to note, however, that these are general guidelines and that cutoffs are both laboratory- and practice-specific.
FIGURE 2 Monthly and lifetime variations in estradiol and FSH

2 | Clomiphene citrate—more sensitive than FSH testing
Like basal FSH testing, the CCCT is an indirect assessment of ovarian reserve. Unlike FSH testing, the CCCT is provocative. It involves administration of 100 mg of clomiphene citrate (Clomid) on days 5 through 9 of the menstrual cycle, with FSH and estradiol measured on days 3 and 10. Once clomiphene citrate is administered, FSH and LH levels rise, followed by an increase in estradiol and inhibin. Evidence suggests that the smaller follicular cohorts in women with diminished ovarian reserve produce less inhibin-B and estradiol and, therefore, less negative feedback on clomiphene-induced pituitary FSH release.6,7 The result: persistent elevation of the day 10 FSH value and a positive screen for diminished ovarian reserve.
In some women, day 10 FSH is elevated even after a normal day 3 value. This makes the CCCT more sensitive than basal FSH testing; it can identify women who might go unrecognized if evaluated by day 3 FSH and estradiol levels alone.
More expensive and labor-intensive than the alternatives
Interpretation of the CCCT requires that FSH and estradiol both be assessed on days 3 and 10. An elevated FSH (≥10 mIU/mL) on either day indicates diminished ovarian reserve. As with basal FSH testing, elevated estradiol (≥80 pg/mL) on day 3 is considered abnormal. The day 10 estradiol value of the CCCT reflects whether or not clomiphene citrate was administered appropriately, and should be elevated. However, the significance of the day 10 estradiol level has been debated with respect to its predictive value for pregnancy in infertile populations.8
The addition of day 10 FSH assessment improves the sensitivity of the CCCT over basal FSH measurement, but makes it a more expensive and labor-intensive test ( TABLE ).5,6 The CCCT involves administration of clomiphene citrate, a safe drug (though it can have side effects), and two blood draws instead of one. Nevertheless, both tests are relatively noninvasive, rapid measures of ovarian reserve.
Drawbacks of the tests
Both basal FSH testing and the CCCT are widely used, although support for their ability to predict ovarian reserve in the infertile population has been challenged recently. Newer data demonstrate that these tests are limited in their ability to predict outcome (pregnancy and response to superovulation drugs) in all but a narrow group of patients undergoing IVF. Performance is particularly limited in:
Additional drawbacks of basal FSH testing and the CCCT include:
- significant variability of test results from cycle to cycle (intercycle variability)
- limited time frame within which the tests can be performed (intracycle variability).
The basal FSH test and CCCT have high specificity (98% to 99% for each) as an assessment of reproductive performance in infertile women and generate few false-positive results.5,6 However, the high screen cutoffs that allow for such specificity come at a price: Few women will screen positive, and sensitivity of the tests is low (between 7% and 8% for basal FSH and between 25% and 40% for the CCCT). Such low sensitivity means that many women will not conceive after infertility treatment despite a normal test result.5,11 Overall, the tests are not highly informative for many women who get tested.
Once abnormal, normal results are meaningless
Once an FSH level or the CCCT has ever been abnormal, the patient has diminished ovarian reserve; normal values in subsequent menstrual cycles do not improve the odds of pregnancy with treatment.14 This fact can be a significant source of confusion and frustration for patients.

How to safeguard the ureter and repair surgical injury
The author has no financial relationships relevant to this article.
CASE: Inadvertent ureteral transection
A gynecologic surgeon operates via Pfannenstiel incision to remove a 12-cm complex left adnexal mass from a 36-year-old obese woman. When she discovers that the mass is densely adherent to the pelvic peritoneum, the surgeon incises the peritoneum lateral to the mass and opens the retroperitoneal space. However, the size and relative immobility of the mass, coupled with the low transverse incision, impair visualization of retroperitoneal structures.
The surgeon clamps and divides the ovarian vessels above the mass but, afterward, suspects that the ureter has been transected and that its ends are included within the clamps. She separates the ovarian vessels above the clamp and ligates them, at which time transection of the ureter is confirmed.
How should she proceed?
The ureter is intimately associated with the female internal genitalia in a way that challenges the gynecologic surgeon to avoid it. In a small percentage of cases involving surgical extirpation in a woman who has severe pelvic pathology, ureteral injury may be inevitable.
Several variables predispose a patient to ureteral injury, including limited exposure, as in the opening case. Others include distorted anatomy of the urinary tract relative to internal genitalia and operations that require extensive resection of pelvic tissues.
This article describes:
- prevention and intraoperative recognition of ureteral injury during gynecologic surgery
- management of intraoperatively recognized ureteral injury.
Maintain a high index of suspicion
The surgeon in the opening case has already taken the first and most important step in ensuring a good outcome: She suspected ureteral injury. In high-risk situations, intraoperative recognition of ureteral injury is more likely when the operative field is inspected thoroughly during and at the conclusion of the surgical procedure.
In a high-risk case, the combined use of intravenous indigo carmine, careful inspection of the operative field, cystoscopy, and ureteral dissection is recommended and should be routine.
Common sites of injury
During gynecologic surgery, the ureter is susceptible to injury along its entire course through the pelvis (see “The ureter takes a course fraught with hazard,”).
During adnexectomy, the gonadal vessels are generally ligated 2 to 3 cm above the adnexa. The ureter lies in close proximity to these vessels and may inadvertently be included in the ligation.
During hysterectomy, the ureter is susceptible to injury as it passes through the parametrium a short distance from the uterus and vaginal fornix.
Sutures placed in the posterior lateral cul de sac during prolapse surgery lie near the midpelvic ureter, and sutures placed during vaginal cuff closure, anterior colporrhaphy, and retropubic urethropexy are in close proximity to the trigonal portion of the ureter.
The ureter extends from the renal pelvis to the bladder, with a length that ranges from 25 to 30 cm, depending on the patient’s height. It crosses the pelvic brim near the bifurcation of the common iliac artery, where it becomes the “pelvic” ureter. The abdominal and pelvic portions of the ureter are approximately equal in length.
ILLUSTRATIONS BY ROB FLEWELL FOR OBG MANAGEMENT
The blood supply of the ureter derives from branches of the major arterial system of the lower abdomen and pelvis. These branches reach the medial aspect of the abdominal ureter and the lateral side of the pelvic ureter to form an anastomotic vascular network protected by an adventitial layer surrounding the ureter.
The ureter is attached to the posterior lateral pelvic peritoneum running dorsal to ovarian vessels. At the midpelvis, it separates from the peritoneum to pierce the base of the broad ligament underneath the uterine artery. At this point, the ureter is about 1.5 to 2 cm lateral to the uterus and curves medially and ventrally, tunneling through the cardinal and vesicovaginal ligaments to enter the bladder trigone.
Risky procedures
In gynecologic surgery, ureteral injury occurs most often during abdominal hysterectomy—probably because of how frequently this operation is performed and the range of pathology managed. The incidence of ureteral injury is much higher during abdominal hysterectomy than vaginal hysterectomy.1-4
Laparoscopic hysterectomy also has been associated with a higher incidence of ureteral injury, especially in the early phase of training.5,6 Possible explanations include:
- greater difficulty identifying the ureter
- a steeper learning curve
- more frequent use of energy to hemostatically divide pedicles, with the potential for thermal injury
- less traction–countertraction, resulting in dissection closer to the ureter
- management of complex pathology.
Although the overall incidence of ureteral injury during adnexectomy is low, it is probably much higher in women undergoing this procedure after a previous hysterectomy or in the presence of complex adnexal pathology.
When injury is likely
Compromised exposure, distorted anatomy, and certain procedures can heighten the risk of ureteral injury. Large tumors may limit the ability of the surgeon to visualize or palpate the ureter (FIGURE 1). Extensive adhesions may cause similar difficulties, and a small incision or obesity may hinder identification of pelvic sidewall structures.
A number of pathologic conditions can distort the anatomy of the ureter, especially as it relates to the female genital tract:
- Malignancies such as ovarian cancer often encroach on and occasionally encase the ureter
- Pelvic inflammatory disease, endometriosis, and a history of surgery or pelvic radiotherapy can retract and encase the ureter toward the gynecologic tract
- Some masses expand against the lower ureter, such as cervical or broad-ligament leiomyomata or placenta previa with accreta
- During vaginal hysterectomy for complete uterine prolapse, the ureters frequently extend beyond the introitus well within the operative field
- Congenital anomalies of the ureter or hydroureter can also cause distortion.
Even in the presence of relatively normal anatomy, certain procedures predispose the ureter to injury. For example, radical hysterectomy involves the almost complete separation of the pelvic ureter from the gynecologic tract and its surrounding soft tissue. When pelvic pathology is significant, the plane of dissection will always be near the ureter.
FIGURE 1 Access to the ureter is obstructed, putting it in jeopardy
Large tumors may limit the ability of the surgeon to visualize or palpate the ureter.
Prevention is the best strategy
At least 50% of ureteral injuries reported during gynecologic surgery have occurred in the absence of a recognizable risk factor.2,7 Nevertheless, knowledge of anatomy and the ability to recognize situations in which there is an elevated risk for ureteral injury will best enable the surgeon to prevent such injury.
When a high-risk situation is encountered, critical preventive steps include:
- adequate exposure
- competent assistance
- exposure of the path of the ureter through the planned course of dissection. Dissecting the ureter beyond this area is usually unnecessary and may itself cause injury.
Skip preoperative IVP in most cases
The vast majority of women who undergo gynecologic surgery do not benefit from preoperative intravenous pyelography (IVP). This measure does not appear to reduce the likelihood of ureteral injury, even in the face of obvious gynecologic disease. However, preoperative identification of obvious ureteral involvement by the disease process is useful. In such cases, the plane of dissection will probably lie closer to the ureter. One of the goals of surgery will then be to clear the urinary tract from the affected area.
When there is a high index of suspicion of an abnormality such as obstruction, intrinsic ureteral endometriosis, or congenital anomaly, preoperative IVP is indicated.
A stent may be helpful in some cases
Ureteral stents are sometimes placed in order to aid in identification and dissection of the ureters during surgery. Some authors of reports on this topic, including Hoffman, believe that stents are useful in certain situations, such as excision of an ovarian remnant, radical vaginal hysterectomy, and when pelvic organs are encased by malignant ovarian tumors. However, stents do not clearly reduce the risk of injury and, in some cases, may increase the risk by providing a false sense of security and predisposing the ureter to adventitial injury during difficult dissection.
Anticipate the effects of disease
The surgeon must have a thorough knowledge of the gynecologic disease process as it relates to surgery involving the urinary tract. For example, an ovarian remnant will almost always be somewhat densely adherent to the pelvic ureter. When severe endometriosis involves the posterior leaf of the broad ligament, the ureter will often be fibrotically retracted toward the operative field.
Certain procedures have special challenges. During resection of adnexa, for example, it is important that the ureter be identified in the retroperitoneum before the ovarian vessels are ligated. During hysterectomy, soft tissues that contain the bladder and ureters should be mobilized caudally and laterally, respectively, creating a U-shaped region (“U” for urinary tract, FIGURE 2) to which the surgeon must limit dissection.
FIGURE 2 During hysterectomy, mobilize the bladder and ureter
Mobilize the soft tissues that contain the bladder and ureters caudally and laterally, respectively, creating a U-shaped region. During division of the paracervical tissues, the surgeon must remain within this region.
Intraoperative detection
Two main types of ureteral injury occur during gynecologic surgery: transection and destruction. The latter includes ligation, crushing, devascularization, and thermal injury.
Intraoperative detection of ureteral injury is more likely when the surgeon recognizes at the outset that the operation places the ureter at increased risk. When dissection has been difficult or complicated for any reason, be concerned about possible injury.
In general, ureteral injury is first recognized by careful inspection of the surgical field. Begin by instilling 5 ml of indigo carmine intravenously. Once the dye begins to appear in the Foley catheter, inspect the area of dissection under a small amount of irrigation fluid, looking for extravasation of dye that indicates partial or complete transection.
If no injury is identified, cystoscopy is the next step. I perform all major abdominal operations with the patient in the low lithotomy position, which provides easy access to the perineum. Cystoscopic identification of urine jetting from both ureteral orifices confirms patency. When only wisps of dye are observed, it is likely that the ureter in question has been partially occluded (e.g., by acute angulation). Failure of any urine to appear from one of the orifices highly suggests injury to that ureter.
During inspection of the operative field, attempt to pass a ureteral stent into the affected orifice. If the stent passes easily and dyed urine is seen to drip freely from it, look for possible angulation of the ureter. If you find none, remove the stent and inspect the orifice again for jetting urine.
If the ureteral stent will move only a few centimeters into the ureteral orifice, ligation (with or without transection) is likely. In this case, leave the stent in place. If the operative site is readily accessible, dissect the applicable area to identify the problem. Depending on the circumstances, you may wish to infuse dye through the stent to aid in operative identification or radiographic evaluation.
Intraoperative IVP may be useful, especially when cystoscopy is unavailable.
Fundamentals of repair
Repair of major injury to the pelvic ureter is generally best accomplished by ureteroneocystostomy or, in selected cases involving injury to the proximal pelvic ureter, by ureteroureterostomy.
When intraoperatively recognized injury to the pelvic ureter appears to be minor, it can be managed by placing a ureteral stent and a closed-suction pelvic drain. Also consider wrapping the injured area with vascularized tissue such as perivesical fat. Minor lacerations can be closed perpendicular to the axis of the ureter using interrupted 4-0 delayed absorbable suture.
Most injuries to the pelvic ureter are optimally managed by ureteroneocystostomy (FIGURE 3). When a significant portion of the pelvic ureter has been lost, ureteroneocystostomy usually requires a combination of:
- extensive mobilization of the bladder
- conservative mobilization of the ureter
- elongation of the bladder
- psoas hitch.
When necessary, mobilization of the kidney with suturing of the caudal perinephric fascia to the psoas muscle will bridge an additional 2- to 3-cm gap.
Major injury to the distal half of the pelvic ureter is repaired using straightforward ureteroneocystostomy.
When there is no significant pelvic disease and the distal ureter is healthy, injury to the proximal pelvic ureter during division of the ovarian vessels may be repaired via ureteroureterostomy. If the ureteral ends will be anastomosed on tension or there is any question about the integrity of the distal portion of the ureter, as when extensive distal ureterolysis has been necessary, consider ureteroneocystostomy.
FIGURE 3 When the distal ureter is injured
Most injuries to the pelvic ureter are managed optimally by ureteroneocystostomy.
Ureter injured during emergent hysterectomy
A 37-year-old woman, para 4, undergoes her fourth repeat cesarean section. When the OB attempts to manually extract the placenta, the patient begins to hemorrhage profusely. Conservative measures fail to stop the bleeding, and the patient becomes hypotensive. The physician performs emergent hysterectomy, taking large pedicles of tissue. Although the patient stabilizes, the doctor worries that the ureters may have been injured.
Resolution: Cystoscopy is performed to check for injury. Because indigo carmine does not spill from the left ureteral orifice, the physician passes a stent with the abdomen still open, and it stops within the most distal ligamentous pedicle. Upon deligation, indigo carmine begins to drain from the stent, which then passes easily.
The stent is withdrawn to below the site of injury, and dilute methylene blue is instilled through it while the ureter is observed under irrigation. No extravasation is noted. Because the ligature had been around a block of tissue that was thought to have acutely angulated rather than incorporated the ureter, the physician concludes that severe damage is unlikely. He places a 6 French double-J stent, wraps the damaged portion of the distal ureter in perivesical fat, and places a closed-suction pelvic drain. Healing is uneventful.
Obstruction is confirmed. Now the surgeon must find it
A 45-year-old woman, para 3, who has a symptomatic 14-weeks’ size myomatous uterus, undergoes vaginal hysterectomy. The surgeon ligates and divides the uterine vessel pedicles before beginning morcellation. At the completion of the procedure, during cystoscopy, indigo carmine fails to spill from the right ureteral orifice, suggesting injury to that ureter. The surgeon passes a stent into the ureter, and it stops approximately 6 cm from the orifice. A retrograde pyelogram confirms complete obstruction.
Resolution: With the stent left in place, the surgeon performs a midline laparotomy, tracing the ureter to the uterine artery pedicle in which it has been incorporated and transected. The distal ureter with the stent is found within soft tissue lateral to the cardinal ligament pedicle, and the transected end is securely ligated using 2–0 silk suture. After the bladder is mobilized, a ureteroneocystostomy is performed. The patient recovers fully.
Postoperative management
After repair of a ureteral injury, leave a closed-suction pelvic drain in place for 2 to 3 days so that any major urinary leak can be detected; it also enhances spontaneous closure and helps prevent potentially infected fluid from accumulating in the region of anastomosis.
The cystotomy performed during ureteroneocystostomy generally heals quickly with a low risk of complications.
Leave a large-bore (20 or 22 French) urethral Foley catheter in place for 2 weeks.
I recommend that a 6 French double-J ureteral stent be left in place for 6 weeks. Potential benefits of the stent include:
- prevention of stricture
- stabilization and immobilization of the ureter during healing
- reduced risk of extravasation of urine
- reduced risk of angulation of the ureter
- isolation of the repair from infection, retroperitoneal fibrosis, and cancer.
I perform IVP approximately 1 week after stent removal to ensure ureteral patency.
CASE RESOLVED
Exposure is improved by widening the incision and dividing the tendonous insertions of the rectus abdominus muscles. The surgeon then removes the mass, preserving the distal ureter, which is estimated to be 12 cm in length and to have intact adventitia.
The surgeon performs a double-spatulated end-to-end ureteroureterostomy over a 6 French double-J ureteral stent that has been passed proximally into the renal pelvis and distally into the bladder. The stent is removed 6 weeks postoperatively, and an IVP the following week demonstrates excellent patency.
The majority of payers consider ureterolysis integral to good surgical technique, but there can be exceptions when documentation supports existing codes. Three CPT codes describe this procedure:
50715 Ureterolysis, with or without repositioning of ureter for retroperitoneal fibrosis
50722 Ureterolysis for ovarian vein syndrome
50725 Ureterolysis for retrocaval ureter, with reanastomosis of upper urinary tract or vena cava
The key to getting paid will be to document the existence of the condition indicated by each of the codes.
The ICD-9 code for both retroperitoneal fibrosis and ovarian vein syndrome is the same, 593.4 (Other ureteric obstruction). If the patient requires ureterolysis for a retrocaval ureter, the code 753.4 (Other specified anomalies of ureter) would be reported instead. Note, however, that these procedure codes cannot be reported if the ureterolysis is performed laparoscopically. In that case, the most appropriate code is 50949 (Unlisted laparoscopy procedure, ureter).
When repair is necessary, you have several codes to choose from, but the supporting diagnosis code 998.2 (Accidental puncture or laceration during a procedure) must be indicated. If a Medicare patient is involved, the surgeon who created the injury would not be paid additionally for repair.

CASE: Inadvertent ureteral transection
A gynecologic surgeon operates via Pfannenstiel incision to remove a 12-cm complex left adnexal mass from a 36-year-old obese woman. When she discovers that the mass is densely adherent to the pelvic peritoneum, the surgeon incises the peritoneum lateral to the mass and opens the retroperitoneal space. However, the size and relative immobility of the mass, coupled with the low transverse incision, impair visualization of retroperitoneal structures.
The surgeon clamps and divides the ovarian vessels above the mass but, afterward, suspects that the ureter has been transected and that its ends are included within the clamps. She separates the ovarian vessels above the clamp and ligates them, at which time transection of the ureter is confirmed.
How should she proceed?
The ureter is intimately associated with the female internal genitalia in a way that challenges the gynecologic surgeon to avoid it. In a small percentage of cases involving surgical extirpation in a woman who has severe pelvic pathology, ureteral injury may be inevitable.
Several variables predispose a patient to ureteral injury, including limited exposure, as in the opening case. Others include distorted anatomy of the urinary tract relative to internal genitalia and operations that require extensive resection of pelvic tissues.
This article describes:
- prevention and intraoperative recognition of ureteral injury during gynecologic surgery
- management of intraoperatively recognized ureteral injury.
Maintain a high index of suspicion
The surgeon in the opening case has already taken the first and most important step in ensuring a good outcome: She suspected ureteral injury. In high-risk situations, intraoperative recognition of ureteral injury is more likely when the operative field is inspected thoroughly during and at the conclusion of the surgical procedure.
In a high-risk case, the combined use of intravenous indigo carmine, careful inspection of the operative field, cystoscopy, and ureteral dissection is recommended and should be routine.
Common sites of injury
During gynecologic surgery, the ureter is susceptible to injury along its entire course through the pelvis (see “The ureter takes a course fraught with hazard,”).
During adnexectomy, the gonadal vessels are generally ligated 2 to 3 cm above the adnexa. The ureter lies in close proximity to these vessels and may inadvertently be included in the ligation.
During hysterectomy, the ureter is susceptible to injury as it passes through the parametrium a short distance from the uterus and vaginal fornix.
Sutures placed in the posterior lateral cul de sac during prolapse surgery lie near the midpelvic ureter, and sutures placed during vaginal cuff closure, anterior colporrhaphy, and retropubic urethropexy are in close proximity to the trigonal portion of the ureter.
The ureter extends from the renal pelvis to the bladder, with a length that ranges from 25 to 30 cm, depending on the patient’s height. It crosses the pelvic brim near the bifurcation of the common iliac artery, where it becomes the “pelvic” ureter. The abdominal and pelvic portions of the ureter are approximately equal in length.
ILLUSTRATIONS BY ROB FLEWELL FOR OBG MANAGEMENT
The blood supply of the ureter derives from branches of the major arterial system of the lower abdomen and pelvis. These branches reach the medial aspect of the abdominal ureter and the lateral side of the pelvic ureter to form an anastomotic vascular network protected by an adventitial layer surrounding the ureter.
The ureter is attached to the posterior lateral pelvic peritoneum running dorsal to ovarian vessels. At the midpelvis, it separates from the peritoneum to pierce the base of the broad ligament underneath the uterine artery. At this point, the ureter is about 1.5 to 2 cm lateral to the uterus and curves medially and ventrally, tunneling through the cardinal and vesicovaginal ligaments to enter the bladder trigone.
Risky procedures
In gynecologic surgery, ureteral injury occurs most often during abdominal hysterectomy—probably because of how frequently this operation is performed and the range of pathology managed. The incidence of ureteral injury is much higher during abdominal hysterectomy than vaginal hysterectomy.1-4
Laparoscopic hysterectomy also has been associated with a higher incidence of ureteral injury, especially in the early phase of training.5,6 Possible explanations include:
- greater difficulty identifying the ureter
- a steeper learning curve
- more frequent use of energy to hemostatically divide pedicles, with the potential for thermal injury
- less traction–countertraction, resulting in dissection closer to the ureter
- management of complex pathology.
Although the overall incidence of ureteral injury during adnexectomy is low, it is probably much higher in women undergoing this procedure after a previous hysterectomy or in the presence of complex adnexal pathology.
When injury is likely
Compromised exposure, distorted anatomy, and certain procedures can heighten the risk of ureteral injury. Large tumors may limit the ability of the surgeon to visualize or palpate the ureter (FIGURE 1). Extensive adhesions may cause similar difficulties, and a small incision or obesity may hinder identification of pelvic sidewall structures.
A number of pathologic conditions can distort the anatomy of the ureter, especially as it relates to the female genital tract:
- Malignancies such as ovarian cancer often encroach on and occasionally encase the ureter
- Pelvic inflammatory disease, endometriosis, and a history of surgery or pelvic radiotherapy can retract and encase the ureter toward the gynecologic tract
- Some masses expand against the lower ureter, such as cervical or broad-ligament leiomyomata or placenta previa with accreta
- During vaginal hysterectomy for complete uterine prolapse, the ureters frequently extend beyond the introitus well within the operative field
- Congenital anomalies of the ureter or hydroureter can also cause distortion.
Even in the presence of relatively normal anatomy, certain procedures predispose the ureter to injury. For example, radical hysterectomy involves the almost complete separation of the pelvic ureter from the gynecologic tract and its surrounding soft tissue. When pelvic pathology is significant, the plane of dissection will always be near the ureter.

The vast majority of women who undergo gynecologic surgery do not benefit from preoperative intravenous pyelography (IVP). This measure does not appear to reduce the likelihood of ureteral injury, even in the face of obvious gynecologic disease. However, preoperative identification of obvious ureteral involvement by the disease process is useful. In such cases, the plane of dissection will probably lie closer to the ureter. One of the goals of surgery will then be to clear the urinary tract from the affected area.
When there is a high index of suspicion of an abnormality such as obstruction, intrinsic ureteral endometriosis, or congenital anomaly, preoperative IVP is indicated.
A stent may be helpful in some cases
Ureteral stents are sometimes placed in order to aid in identification and dissection of the ureters during surgery. Some authors of reports on this topic, including Hoffman, believe that stents are useful in certain situations, such as excision of an ovarian remnant, radical vaginal hysterectomy, and when pelvic organs are encased by malignant ovarian tumors. However, stents do not clearly reduce the risk of injury and, in some cases, may increase the risk by providing a false sense of security and predisposing the ureter to adventitial injury during difficult dissection.

Intraoperative detection
Two main types of ureteral injury occur during gynecologic surgery: transection and destruction. The latter includes ligation, crushing, devascularization, and thermal injury.
Intraoperative detection of ureteral injury is more likely when the surgeon recognizes at the outset that the operation places the ureter at increased risk. When dissection has been difficult or complicated for any reason, be concerned about possible injury.

If the stent passes easily and dyed urine is seen to drip freely from it, look for possible angulation of the ureter. If you find none, remove the stent and inspect the orifice again for jetting urine.
If the ureteral stent will move only a few centimeters into the ureteral orifice, ligation (with or without transection) is likely. In this case, leave the stent in place. If the operative site is readily accessible, dissect the applicable area to identify the problem. Depending on the circumstances, you may wish to infuse dye through the stent to aid in operative identification or radiographic evaluation.
Intraoperative IVP may be useful, especially when cystoscopy is unavailable.
Fundamentals of repair
Repair of major injury to the pelvic ureter is generally best accomplished by ureteroneocystostomy or, in selected cases involving injury to the proximal pelvic ureter, by ureteroureterostomy.
When intraoperatively recognized injury to the pelvic ureter appears to be minor, it can be managed by placing a ureteral stent and a closed-suction pelvic drain. Also consider wrapping the injured area with vascularized tissue such as perivesical fat. Minor lacerations can be closed perpendicular to the axis of the ureter using interrupted 4-0 delayed absorbable suture.
Most injuries to the pelvic ureter are optimally managed by ureteroneocystostomy (FIGURE 3). When a significant portion of the pelvic ureter has been lost, ureteroneocystostomy usually requires a combination of:

- conservative mobilization of the ureter
- elongation of the bladder

When necessary, mobilization of the kidney with suturing of the caudal perinephric fascia to the psoas muscle will bridge an additional 2- to 3-cm gap.
Major injury to the distal half of the pelvic ureter is repaired using straightforward ureteroneocystostomy.
When there is no significant pelvic disease and the distal ureter is healthy, injury to the proximal pelvic ureter during division of the ovarian vessels may be repaired via ureteroureterostomy. If the ureteral ends will be anastomosed on tension or there is any question about the integrity of the distal portion of the ureter, as when extensive distal ureterolysis has been necessary, consider ureteroneocystostomy.

Conservative measures fail to stop the bleeding, and the patient becomes hypotensive. The physician performs emergent hysterectomy, taking large pedicles of tissue.

Because indigo carmine does not spill from the left ureteral orifice, the physician passes a stent with the abdomen still open, and it stops within the most distal ligamentous pedicle. Upon deligation, indigo carmine begins to drain from the stent, which then passes easily.
The stent is withdrawn to below the site of injury, and dilute methylene blue is instilled through it while the ureter is observed under irrigation. No extravasation is noted. Because the ligature had been around a block of tissue that was thought to have acutely angulated rather than incorporated the ureter, the physician concludes that severe damage is unlikely. He places a 6 French double-J stent, wraps the damaged portion of the distal ureter in perivesical fat, and places a closed-suction pelvic drain. Healing is uneventful.
Obstruction is confirmed. Now the surgeon must find it
A 45-year-old woman, para 3, who has a symptomatic 14-weeks’ size myomatous uterus, undergoes vaginal hysterectomy. The surgeon ligates and divides the uterine vessel pedicles before beginning morcellation. At the completion of the procedure, during cystoscopy, indigo carmine fails to spill from the right ureteral orifice, suggesting injury to that ureter. The surgeon passes a stent into the ureter, and it stops approximately 6 cm from the orifice. A retrograde pyelogram confirms complete obstruction.

The distal ureter with the stent is found within soft tissue lateral to the cardinal ligament pedicle, and the transected end is securely ligated using 2–0 silk suture. After the bladder is mobilized, a ureteroneocystostomy is performed. The patient recovers fully.
Postoperative management
After repair of a ureteral injury, leave a closed-suction pelvic drain in place for 2 to 3 days so that any major urinary leak can be detected; it also enhances spontaneous closure and helps prevent potentially infected fluid from accumulating in the region of anastomosis.
The cystotomy performed during ureteroneocystostomy generally heals quickly with a low risk of complications.
Leave a large-bore (20 or 22 French) urethral Foley catheter in place for 2 weeks.
I recommend that a 6 French double-J ureteral stent be left in place for 6 weeks. Potential benefits of the stent include:
- prevention of stricture
- stabilization and immobilization of the ureter during healing
- reduced risk of extravasation of urine
- reduced risk of angulation of the ureter
- isolation of the repair from infection, retroperitoneal fibrosis, and cancer.
I perform IVP approximately 1 week after stent removal to ensure ureteral patency.
CASE RESOLVED
Exposure is improved by widening the incision and dividing the tendonous insertions of the rectus abdominus muscles. The surgeon then removes the mass, preserving the distal ureter, which is estimated to be 12 cm in length and to have intact adventitia.

Several variables predispose a patient to ureteral injury, including limited exposure, as in the opening case. Others include distorted anatomy of the urinary tract relative to internal genitalia and operations that require extensive resection of pelvic tissues.
This article describes:
- prevention and intraoperative recognition of ureteral injury during gynecologic surgery
- management of intraoperatively recognized ureteral injury.
Maintain a high index of suspicion
The surgeon in the opening case has already taken the first and most important step in ensuring a good outcome: She suspected ureteral injury. In high-risk situations, intraoperative recognition of ureteral injury is more likely when the operative field is inspected thoroughly during and at the conclusion of the surgical procedure.
In a high-risk case, the combined use of intravenous indigo carmine, careful inspection of the operative field, cystoscopy, and ureteral dissection is recommended and should be routine.
Common sites of injury
During gynecologic surgery, the ureter is susceptible to injury along its entire course through the pelvis (see “The ureter takes a course fraught with hazard,”).
During adnexectomy, the gonadal vessels are generally ligated 2 to 3 cm above the adnexa. The ureter lies in close proximity to these vessels and may inadvertently be included in the ligation.
During hysterectomy, the ureter is susceptible to injury as it passes through the parametrium a short distance from the uterus and vaginal fornix.
Sutures placed in the posterior lateral cul de sac during prolapse surgery lie near the midpelvic ureter, and sutures placed during vaginal cuff closure, anterior colporrhaphy, and retropubic urethropexy are in close proximity to the trigonal portion of the ureter.
The ureter extends from the renal pelvis to the bladder, with a length that ranges from 25 to 30 cm, depending on the patient’s height. It crosses the pelvic brim near the bifurcation of the common iliac artery, where it becomes the “pelvic” ureter. The abdominal and pelvic portions of the ureter are approximately equal in length.
ILLUSTRATIONS BY ROB FLEWELL FOR OBG MANAGEMENT
The blood supply of the ureter derives from branches of the major arterial system of the lower abdomen and pelvis. These branches reach the medial aspect of the abdominal ureter and the lateral side of the pelvic ureter to form an anastomotic vascular network protected by an adventitial layer surrounding the ureter.
The ureter is attached to the posterior lateral pelvic peritoneum running dorsal to ovarian vessels. At the midpelvis, it separates from the peritoneum to pierce the base of the broad ligament underneath the uterine artery. At this point, the ureter is about 1.5 to 2 cm lateral to the uterus and curves medially and ventrally, tunneling through the cardinal and vesicovaginal ligaments to enter the bladder trigone.
Risky procedures
In gynecologic surgery, ureteral injury occurs most often during abdominal hysterectomy—probably because of how frequently this operation is performed and the range of pathology managed. The incidence of ureteral injury is much higher during abdominal hysterectomy than vaginal hysterectomy.1-4
Laparoscopic hysterectomy also has been associated with a higher incidence of ureteral injury, especially in the early phase of training.5,6 Possible explanations include:
- greater difficulty identifying the ureter
- a steeper learning curve
- more frequent use of energy to hemostatically divide pedicles, with the potential for thermal injury
- less traction–countertraction, resulting in dissection closer to the ureter
- management of complex pathology.
Although the overall incidence of ureteral injury during adnexectomy is low, it is probably much higher in women undergoing this procedure after a previous hysterectomy or in the presence of complex adnexal pathology.
When injury is likely
Compromised exposure, distorted anatomy, and certain procedures can heighten the risk of ureteral injury. Large tumors may limit the ability of the surgeon to visualize or palpate the ureter (FIGURE 1). Extensive adhesions may cause similar difficulties, and a small incision or obesity may hinder identification of pelvic sidewall structures.
A number of pathologic conditions can distort the anatomy of the ureter, especially as it relates to the female genital tract:
- Malignancies such as ovarian cancer often encroach on and occasionally encase the ureter
- Pelvic inflammatory disease, endometriosis, and a history of surgery or pelvic radiotherapy can retract and encase the ureter toward the gynecologic tract
- Some masses expand against the lower ureter, such as cervical or broad-ligament leiomyomata or placenta previa with accreta
- During vaginal hysterectomy for complete uterine prolapse, the ureters frequently extend beyond the introitus well within the operative field
- Congenital anomalies of the ureter or hydroureter can also cause distortion.
Even in the presence of relatively normal anatomy, certain procedures predispose the ureter to injury. For example, radical hysterectomy involves the almost complete separation of the pelvic ureter from the gynecologic tract and its surrounding soft tissue. When pelvic pathology is significant, the plane of dissection will always be near the ureter.
FIGURE 1 Access to the ureter is obstructed, putting it in jeopardy
Large tumors may limit the ability of the surgeon to visualize or palpate the ureter.
Prevention is the best strategy
At least 50% of ureteral injuries reported during gynecologic surgery have occurred in the absence of a recognizable risk factor.2,7 Nevertheless, knowledge of anatomy and the ability to recognize situations in which there is an elevated risk for ureteral injury will best enable the surgeon to prevent such injury.
When a high-risk situation is encountered, critical preventive steps include:
- adequate exposure
- competent assistance
- exposure of the path of the ureter through the planned course of dissection. Dissecting the ureter beyond this area is usually unnecessary and may itself cause injury.
Skip preoperative IVP in most cases
The vast majority of women who undergo gynecologic surgery do not benefit from preoperative intravenous pyelography (IVP). This measure does not appear to reduce the likelihood of ureteral injury, even in the face of obvious gynecologic disease. However, preoperative identification of obvious ureteral involvement by the disease process is useful. In such cases, the plane of dissection will probably lie closer to the ureter. One of the goals of surgery will then be to clear the urinary tract from the affected area.
When there is a high index of suspicion of an abnormality such as obstruction, intrinsic ureteral endometriosis, or congenital anomaly, preoperative IVP is indicated.
A stent may be helpful in some cases
Ureteral stents are sometimes placed in order to aid in identification and dissection of the ureters during surgery. Some authors of reports on this topic, including Hoffman, believe that stents are useful in certain situations, such as excision of an ovarian remnant, radical vaginal hysterectomy, and when pelvic organs are encased by malignant ovarian tumors. However, stents do not clearly reduce the risk of injury and, in some cases, may increase the risk by providing a false sense of security and predisposing the ureter to adventitial injury during difficult dissection.
Anticipate the effects of disease
The surgeon must have a thorough knowledge of the gynecologic disease process as it relates to surgery involving the urinary tract. For example, an ovarian remnant will almost always be somewhat densely adherent to the pelvic ureter. When severe endometriosis involves the posterior leaf of the broad ligament, the ureter will often be fibrotically retracted toward the operative field.
Certain procedures have special challenges. During resection of adnexa, for example, it is important that the ureter be identified in the retroperitoneum before the ovarian vessels are ligated. During hysterectomy, soft tissues that contain the bladder and ureters should be mobilized caudally and laterally, respectively, creating a U-shaped region (“U” for urinary tract, FIGURE 2) to which the surgeon must limit dissection.
FIGURE 2 During hysterectomy, mobilize the bladder and ureter
Mobilize the soft tissues that contain the bladder and ureters caudally and laterally, respectively, creating a U-shaped region. During division of the paracervical tissues, the surgeon must remain within this region.
Intraoperative detection
Two main types of ureteral injury occur during gynecologic surgery: transection and destruction. The latter includes ligation, crushing, devascularization, and thermal injury.
Intraoperative detection of ureteral injury is more likely when the surgeon recognizes at the outset that the operation places the ureter at increased risk. When dissection has been difficult or complicated for any reason, be concerned about possible injury.
In general, ureteral injury is first recognized by careful inspection of the surgical field. Begin by instilling 5 ml of indigo carmine intravenously. Once the dye begins to appear in the Foley catheter, inspect the area of dissection under a small amount of irrigation fluid, looking for extravasation of dye that indicates partial or complete transection.
If no injury is identified, cystoscopy is the next step. I perform all major abdominal operations with the patient in the low lithotomy position, which provides easy access to the perineum. Cystoscopic identification of urine jetting from both ureteral orifices confirms patency. When only wisps of dye are observed, it is likely that the ureter in question has been partially occluded (e.g., by acute angulation). Failure of any urine to appear from one of the orifices highly suggests injury to that ureter.
During inspection of the operative field, attempt to pass a ureteral stent into the affected orifice. If the stent passes easily and dyed urine is seen to drip freely from it, look for possible angulation of the ureter. If you find none, remove the stent and inspect the orifice again for jetting urine.
If the ureteral stent will move only a few centimeters into the ureteral orifice, ligation (with or without transection) is likely. In this case, leave the stent in place. If the operative site is readily accessible, dissect the applicable area to identify the problem. Depending on the circumstances, you may wish to infuse dye through the stent to aid in operative identification or radiographic evaluation.
Intraoperative IVP may be useful, especially when cystoscopy is unavailable.
Fundamentals of repair
Repair of major injury to the pelvic ureter is generally best accomplished by ureteroneocystostomy or, in selected cases involving injury to the proximal pelvic ureter, by ureteroureterostomy.
When intraoperatively recognized injury to the pelvic ureter appears to be minor, it can be managed by placing a ureteral stent and a closed-suction pelvic drain. Also consider wrapping the injured area with vascularized tissue such as perivesical fat. Minor lacerations can be closed perpendicular to the axis of the ureter using interrupted 4-0 delayed absorbable suture.
Most injuries to the pelvic ureter are optimally managed by ureteroneocystostomy (FIGURE 3). When a significant portion of the pelvic ureter has been lost, ureteroneocystostomy usually requires a combination of:
- extensive mobilization of the bladder
- conservative mobilization of the ureter
- elongation of the bladder
- psoas hitch.
When necessary, mobilization of the kidney with suturing of the caudal perinephric fascia to the psoas muscle will bridge an additional 2- to 3-cm gap.
Major injury to the distal half of the pelvic ureter is repaired using straightforward ureteroneocystostomy.
When there is no significant pelvic disease and the distal ureter is healthy, injury to the proximal pelvic ureter during division of the ovarian vessels may be repaired via ureteroureterostomy. If the ureteral ends will be anastomosed on tension or there is any question about the integrity of the distal portion of the ureter, as when extensive distal ureterolysis has been necessary, consider ureteroneocystostomy.
FIGURE 3 When the distal ureter is injured
Most injuries to the pelvic ureter are managed optimally by ureteroneocystostomy.
Ureter injured during emergent hysterectomy
A 37-year-old woman, para 4, undergoes her fourth repeat cesarean section. When the OB attempts to manually extract the placenta, the patient begins to hemorrhage profusely. Conservative measures fail to stop the bleeding, and the patient becomes hypotensive. The physician performs emergent hysterectomy, taking large pedicles of tissue. Although the patient stabilizes, the doctor worries that the ureters may have been injured.
Resolution: Cystoscopy is performed to check for injury. Because indigo carmine does not spill from the left ureteral orifice, the physician passes a stent with the abdomen still open, and it stops within the most distal ligamentous pedicle. Upon deligation, indigo carmine begins to drain from the stent, which then passes easily.
The stent is withdrawn to below the site of injury, and dilute methylene blue is instilled through it while the ureter is observed under irrigation. No extravasation is noted. Because the ligature had been around a block of tissue that was thought to have acutely angulated rather than incorporated the ureter, the physician concludes that severe damage is unlikely. He places a 6 French double-J stent, wraps the damaged portion of the distal ureter in perivesical fat, and places a closed-suction pelvic drain. Healing is uneventful.
Obstruction is confirmed. Now the surgeon must find it
A 45-year-old woman, para 3, who has a symptomatic 14-weeks’ size myomatous uterus, undergoes vaginal hysterectomy. The surgeon ligates and divides the uterine vessel pedicles before beginning morcellation. At the completion of the procedure, during cystoscopy, indigo carmine fails to spill from the right ureteral orifice, suggesting injury to that ureter. The surgeon passes a stent into the ureter, and it stops approximately 6 cm from the orifice. A retrograde pyelogram confirms complete obstruction.
Resolution: With the stent left in place, the surgeon performs a midline laparotomy, tracing the ureter to the uterine artery pedicle in which it has been incorporated and transected. The distal ureter with the stent is found within soft tissue lateral to the cardinal ligament pedicle, and the transected end is securely ligated using 2–0 silk suture. After the bladder is mobilized, a ureteroneocystostomy is performed. The patient recovers fully.
Postoperative management
After repair of a ureteral injury, leave a closed-suction pelvic drain in place for 2 to 3 days so that any major urinary leak can be detected; it also enhances spontaneous closure and helps prevent potentially infected fluid from accumulating in the region of anastomosis.
The cystotomy performed during ureteroneocystostomy generally heals quickly with a low risk of complications.
Leave a large-bore (20 or 22 French) urethral Foley catheter in place for 2 weeks.
I recommend that a 6 French double-J ureteral stent be left in place for 6 weeks. Potential benefits of the stent include:
- prevention of stricture
- stabilization and immobilization of the ureter during healing
- reduced risk of extravasation of urine
- reduced risk of angulation of the ureter
- isolation of the repair from infection, retroperitoneal fibrosis, and cancer.
I perform IVP approximately 1 week after stent removal to ensure ureteral patency.
CASE RESOLVED
Exposure is improved by widening the incision and dividing the tendonous insertions of the rectus abdominus muscles. The surgeon then removes the mass, preserving the distal ureter, which is estimated to be 12 cm in length and to have intact adventitia.
The surgeon performs a double-spatulated end-to-end ureteroureterostomy over a 6 French double-J ureteral stent that has been passed proximally into the renal pelvis and distally into the bladder. The stent is removed 6 weeks postoperatively, and an IVP the following week demonstrates excellent patency.
The majority of payers consider ureterolysis integral to good surgical technique, but there can be exceptions when documentation supports existing codes. Three CPT codes describe this procedure:
50715 Ureterolysis, with or without repositioning of ureter for retroperitoneal fibrosis
50722 Ureterolysis for ovarian vein syndrome
50725 Ureterolysis for retrocaval ureter, with reanastomosis of upper urinary tract or vena cava
The key to getting paid will be to document the existence of the condition indicated by each of the codes.
The ICD-9 code for both retroperitoneal fibrosis and ovarian vein syndrome is the same, 593.4 (Other ureteric obstruction). If the patient requires ureterolysis for a retrocaval ureter, the code 753.4 (Other specified anomalies of ureter) would be reported instead. Note, however, that these procedure codes cannot be reported if the ureterolysis is performed laparoscopically. In that case, the most appropriate code is 50949 (Unlisted laparoscopy procedure, ureter).
When repair is necessary, you have several codes to choose from, but the supporting diagnosis code 998.2 (Accidental puncture or laceration during a procedure) must be indicated. If a Medicare patient is involved, the surgeon who created the injury would not be paid additionally for repair.

Challenges in total laparoscopic hysterectomy: Severe adhesions
Dr. Giesler reports that he serves on the speaker’s bureau for Ethicon Endo-Surgery. Dr. Vyas has no financial relationships relevant to this article.
CASE: Probable adhesions. Is laparoscopy practical?
A 54-year-old woman complains of perimenopausal bleeding that has not been controlled by hormone therapy, as well as increasing pelvic pain that has caused her to miss work. She wants you to perform hysterectomy to end these problems once and for all.
Aside from these complaints, her history is unremarkable except for a laparotomy at 13 years for a ruptured appendix. Her Pap smear, endometrial biopsy, and pelvic sonogram are negative.
Is she a candidate for laparoscopic hysterectomy?
A patient such as this one, who has a history of laparotomy, is likely to have extensive intra-abdominal adhesions. This pathology increases the risk of bowel injury during surgery—whether it is performed via laparotomy or laparoscopy.
The ability to simplify laparoscopic hysterectomy in a woman who has extensive adhesions requires an understanding of the ways in which adhesions form—in order to lyse them skillfully and avoid creating further adhesions. It also requires special techniques to enter the abdomen, identify the site of attachment, separate adhered structures, and conclude the hysterectomy. Attention to the type of energy that is used also is important.
In this article, we describe these techniques and considerations.
In Part 1 of this article, we discussed techniques that facilitate laparoscopic hysterectomy in a woman who has a large uterus.
Don’t overlook preoperative discussion, preparation
The patient needs to understand the risks and benefits of laparoscopic hysterectomy, particularly when extensive adhesions are likely, as well as the fact that it may be necessary to convert the procedure to laparotomy if the laparoscopic approach proves too difficult. She also needs to understand that conversion to laparotomy does not represent a failure of the procedure but an aim for greater safety.
Because bowel injury is a real risk when the patient has extensive adhesions, mechanical bowel preparation is important. Choose the regimen preferred by the colorectal surgeon likely to be consulted if intraoperative injury occurs.
The operating room (OR) and anesthesia staffs also need to be prepared, and the patient should be positioned for optimal access in the OR. These and other preoperative steps are described in Part 1 of this article and remain the same for the patient who has extensive intra-abdominal adhesions.
How adhesions form
When the peritoneum is injured, a fibrinous exudate develops, causing adjacent tissues to stick together. Normal peritoneum immediately initiates a process to break down this exudate, but traumatized peritoneum has limited ability to do so. As a result, a permanent adhesion can form in as few as 5 to 8 days.1,2
Pelvic inflammatory disease and intraperitoneal blood associated with distant endometriosis implants are well known causes of abdominal adhesions; others are listed in the TABLE.

The challenge of safe entry
During laparotomy, adhesions can make it difficult to enter the abdomen. The same is true—but more so—for laparoscopic entry. The distortion caused by adhesions can lead to inadvertent injury to blood vessels, bowel, and bladder even in the best surgical hands. An attempt to lyse adhesions laparoscopically often prolongs the surgical procedure and increases the risk of visceral injury, bleeding, and fistula.1
In more than 80% of patients experiencing injury during major abdominal surgery, the injury is associated with omental adhesions to the previous abdominal wall incision, and more than 50% have intestine included in the adhesion complex.1
One study involving 918 patients who underwent laparoscopy found that 54.9% had umbilical adhesions of sufficient size to interfere with umbilical port placement.3 More important, 16% of this study group had only a single midline umbilical incision for laparoscopy before the adhesions were discovered.
The utility of Palmer’s point
Although multiple techniques have been described to minimize entry-related injury, no technique has completely eliminated the risk of inadvertent bowel or major large-vessel injury.3 In 1974, Palmer described an abdominal entry point for the Veress needle and small trocar for women who have a history of abdominal surgery.4 Many surgeons now consider “Palmer’s point,” in the left upper quadrant, as the safest peritoneal entry site.
Technique. After emptying the stomach of its contents using suction, insert the Veress needle into the peritoneal cavity at a point midway between the midclavicular line and the anterior axillary line, 3 cm below the costal margin (FIGURE). Advance it slowly until you hear three pops, signifying entry into the peritoneal cavity. Only minimal insertion is needed; insufflation pressure of less than 10 mm Hg indicates intraperitoneal placement of the needle tip.5
Once pneumoperitoneum pressure of 20 mm Hg is established, insert a 5-mm trocar perpendicular to the abdominal wall, 3 cm below the ribs, midway between the midclavicular line and the anterior axillary line.3 (There is a risk of colon injury at the splenic flexure if the entry point is further lateral.)
Inspect the abdominal cavity with the laparoscope from this access port to determine the best placement of remaining trocars under direct vision; lyse adhesions, if necessary, to perform the procedure.
FIGURE Enter the abdomen at Palmer’s point
This entry site (red dot) lies midway between the midclavicular line and the anterior axillary line, 3 cm below the costal margin. The other port sites (black dots) are described in Figure 2 in Part 1 of this article.
Success depends on careful lysis and minimal tissue injury
Adhesions in the abdomen may involve:
- omentum to peritoneum
- omentum to pelvic structures
- intestine to peritoneum
- intestine to pelvic structures.
Adhesions may be filmy and thin or dense and thick, avascular or vascular. They can be minimal, or a veritable curtain that prevents adequate visualization of the primary surgical site. When they are present, they must be managed successfully if the primary procedure is to be accomplished laparoscopically.
Successful management requires techniques to maximize adhesiolysis and minimize new adhesions or tissue injury:
- Use traction and countertraction to define the line of attachment; this is essential to separate two tissues bound by adhesions.
- Use atraumatic graspers to reduce the risk of tissue laceration.
- Avoid sharp dissection with scissors. Although this is the traditional method of lysis, it is often associated with bleeding that stains and obscures the line of dissection.
- Choose tools wisely. Electrosurgery and lasers use obliterative coagulation, working at temperatures of 150°C to 400°C to burn tissue. Blood and tissue are desiccated and oxidized, forming an eschar that covers and seals the bleeding area. Rebleeding during electrosurgery may occur when the instrument sticks to tissue and disrupts the eschar. In addition, monopolar instruments may cause undetected remote thermal injury, causing late complications.6 Both monopolar and bipolar techniques can also leave carbon particles during the oxidation process that become foci for future adhesions.7
- Consider ultrasonic energy. Unlike electrosurgery, ultrasonic energy is mechanical and works at much lower temperatures (50°C to 100°C), controlling bleeding by coaptive coagulation. The ultrasonic blade, vibrating at 55,500 Hz, disrupts and denatures protein to form a coagulum that seals small coapted vessels. When the effect is prolonged, secondary heat seals larger vessels. Ultrasonic energy involves minimal thermal spread, minimal carbon particle formation, and a cavitation effect similar to hydrodissection that helps expose the adhesive line. It creates minimal smoke, improving visibility. Because ultrasonic energy operates at a lower temperature, less char and necrotic tissue—important causes of adhesions—occur than with bipolar or monopolar electrical energy.7
Although different energy sources interact with human tissue using different mechanisms, clinical outcomes appear to be much the same and depend more on the skill of the individual surgeon than on the power source used. Data on this topic are limited.
Many patients have adhesions that involve omentum or intestine that can be managed using simple laparoscopic techniques, but some have organs that are fixed in the pelvis by adhesions. In these cases, traction and countertraction techniques can be tedious and may cause inadvertent injury to critical structures or excessive bleeding that necessitates conversion to laparotomy.
A better way to approach the obliterated, or “frozen,” pelvis is to open the retroperitoneal space and identify critical structures:
- Enter the retroperitoneal space at the pelvic brim in an area free of adhesions. Identify the ureter and follow it to the bladder. This can be accomplished using hydrodissection techniques or cavitation techniques with ultrasonic energy.
- Skeletonize, coagulate, and cut the vessels once you reach the cardinal ligament and identify the ascending uterine blood supply.
- Dissect the structures of the obliterated cul de sac using standard techniques.
- Use sharp dissection for adhesiolysis. Laparoscopic blunt dissection of adhesions can lead to serosal tears and inadvertent enterotomy. Sharp dissection or mechanical energy devices are preferred to divide the tissue along the line of demarcation—but remember that monopolar and bipolar devices can cause remote thermal damage that goes undetected at the time of use.
When dissection becomes unproductive in one area, switch to another; dissection planes frequently open and demonstrate the relationships between pelvic structures and loops of bowel.8
Occasionally, the visceral peritoneum of the bowel is breached during adhesiolysis. If the mucosa and muscularis remain intact, denuded serosa need not be repaired. Surgical repair is necessary if mucosa is exposed, or perforation may occur.
Because most ObGyn residency programs offer limited training in management of bowel injuries, intraoperative consultation with a general surgeon may be indicated if more than a simple repair is required.8
CASE RESOLVED
You perform total laparoscopic hysterectomy and find multiple adhesions in the right lower quadrant, adjacent to the area of trocar insertion. Small intestine is adherent to the right lateral pelvic wall; sigmoid colon is adherent to the left pelvic wall; and the anterior fundus is adherent to the bladder peritoneal reflection, with the adhesions extending on either side to include the round ligaments.
You begin adhesiolysis in the right lower quadrant to optimize trocar movement. You transect the round ligaments in the mid-position, with dissection extended retroperitoneally on either side to the midline of the lower uterine segment; this opens access to the ascending branch of the uterine vessels. You dissect the intestine free of either pelvic sidewall along the line of demarcation.
Total blood loss is less than 25 mL. The patient is discharged 6 hours after surgery.

Normal peritoneum immediately initiates a process to break down this exudate, but traumatized peritoneum has limited ability to do so. As a result, a permanent adhesion can form in as few as 5 to 8 days.1,2
Pelvic inflammatory disease and intraperitoneal blood associated with distant endometriosis implants are well known causes of abdominal adhesions; others are listed in the TABLE.

The challenge of safe entry
During laparotomy, adhesions can make it difficult to enter the abdomen. The same is true—but more so—for laparoscopic entry. The distortion caused by adhesions can lead to inadvertent injury to blood vessels, bowel, and bladder even in the best surgical hands. An attempt to lyse adhesions laparoscopically often prolongs the surgical procedure and increases the risk of visceral injury, bleeding, and fistula.1
In more than 80% of patients experiencing injury during major abdominal surgery, the injury is associated with omental adhesions to the previous abdominal wall incision, and more than 50% have intestine included in the adhesion complex.1
One study involving 918 patients who underwent laparoscopy found that 54.9% had umbilical adhesions of sufficient size to interfere with umbilical port placement.3 More important, 16% of this study group had only a single midline umbilical incision for laparoscopy before the adhesions were discovered.
The utility of Palmer’s point
Although multiple techniques have been described to minimize entry-related injury, no technique has completely eliminated the risk of inadvertent bowel or major large-vessel injury.3 In 1974, Palmer described an abdominal entry point for the Veress needle and small trocar for women who have a history of abdominal surgery.4 Many surgeons now consider “Palmer’s point,” in the left upper quadrant, as the safest peritoneal entry site.
Technique. After emptying the stomach of its contents using suction, insert the Veress needle into the peritoneal cavity at a point midway between the midclavicular line and the anterior axillary line, 3 cm below the costal margin (FIGURE). Advance it slowly until you hear three pops, signifying entry into the peritoneal cavity. Only minimal insertion is needed; insufflation pressure of less than 10 mm Hg indicates intraperitoneal placement of the needle tip.5
Once pneumoperitoneum pressure of 20 mm Hg is established, insert a 5-mm trocar perpendicular to the abdominal wall, 3 cm below the ribs, midway between the midclavicular line and the anterior axillary line.3 (There is a risk of colon injury at the splenic flexure if the entry point is further lateral.)
Inspect the abdominal cavity with the laparoscope from this access port to determine the best placement of remaining trocars under direct vision; lyse adhesions, if necessary, to perform the procedure.

This entry site (red dot) lies midway between the midclavicular line and the anterior axillary line, 3 cm below the costal margin. The other port sites (black dots) are described in Figure 2 in Part 1 of this article.
Success depends on careful lysis and minimal tissue injury
Adhesions in the abdomen may involve:
- omentum to peritoneum
- omentum to pelvic structures
- intestine to peritoneum
- intestine to pelvic structures.
Adhesions may be filmy and thin or dense and thick, avascular or vascular. They can be minimal, or a veritable curtain that prevents adequate visualization of the primary surgical site. When they are present, they must be managed successfully if the primary procedure is to be accomplished laparoscopically.
Successful management requires techniques to maximize adhesiolysis and minimize new adhesions or tissue injury:
- Use traction and countertraction to define the line of attachment; this is essential to separate two tissues bound by adhesions.
- Use atraumatic graspers to reduce the risk of tissue laceration.
- Avoid sharp dissection with scissors. Although this is the traditional method of lysis, it is often associated with bleeding that stains and obscures the line of dissection.
- Choose tools wisely. Electrosurgery and lasers use obliterative coagulation, working at temperatures of 150°C to 400°C to burn tissue. Blood and tissue are desiccated and oxidized, forming an eschar that covers and seals the bleeding area. Rebleeding during electrosurgery may occur when the instrument sticks to tissue and disrupts the eschar. In addition, monopolar instruments may cause undetected remote thermal injury, causing late complications.6 Both monopolar and bipolar techniques can also leave carbon particles during the oxidation process that become foci for future adhesions.7
- Consider ultrasonic energy. Unlike electrosurgery, ultrasonic energy is mechanical and works at much lower temperatures (50°C to 100°C), controlling bleeding by coaptive coagulation. The ultrasonic blade, vibrating at 55,500 Hz, disrupts and denatures protein to form a coagulum that seals small coapted vessels. When the effect is prolonged, secondary heat seals larger vessels. Ultrasonic energy involves minimal thermal spread, minimal carbon particle formation, and a cavitation effect similar to hydrodissection that helps expose the adhesive line. It creates minimal smoke, improving visibility. Because ultrasonic energy operates at a lower temperature, less char and necrotic tissue—important causes of adhesions—occur than with bipolar or monopolar electrical energy.7
Although different energy sources interact with human tissue using different mechanisms, clinical outcomes appear to be much the same and depend more on the skill of the individual surgeon than on the power source used. Data on this topic are limited.
Many patients have adhesions that involve omentum or intestine that can be managed using simple laparoscopic techniques, but some have organs that are fixed in the pelvis by adhesions. In these cases, traction and countertraction techniques can be tedious and may cause inadvertent injury to critical structures or excessive bleeding that necessitates conversion to laparotomy.
A better way to approach the obliterated, or “frozen,” pelvis is to open the retroperitoneal space and identify critical structures:
- Enter the retroperitoneal space at the pelvic brim in an area free of adhesions. Identify the ureter and follow it to the bladder. This can be accomplished using hydrodissection techniques or cavitation techniques with ultrasonic energy.
- Skeletonize, coagulate, and cut the vessels once you reach the cardinal ligament and identify the ascending uterine blood supply.
- Dissect the structures of the obliterated cul de sac using standard techniques.
- Use sharp dissection for adhesiolysis. Laparoscopic blunt dissection of adhesions can lead to serosal tears and inadvertent enterotomy. Sharp dissection or mechanical energy devices are preferred to divide the tissue along the line of demarcation—but remember that monopolar and bipolar devices can cause remote thermal damage that goes undetected at the time of use.
When dissection becomes unproductive in one area, switch to another; dissection planes frequently open and demonstrate the relationships between pelvic structures and loops of bowel.8
Occasionally, the visceral peritoneum of the bowel is breached during adhesiolysis. If the mucosa and muscularis remain intact, denuded serosa need not be repaired. Surgical repair is necessary if mucosa is exposed, or perforation may occur.
Because most ObGyn residency programs offer limited training in management of bowel injuries, intraoperative consultation with a general surgeon may be indicated if more than a simple repair is required.8
CASE RESOLVED
You perform total laparoscopic hysterectomy and find multiple adhesions in the right lower quadrant, adjacent to the area of trocar insertion. Small intestine is adherent to the right lateral pelvic wall; sigmoid colon is adherent to the left pelvic wall; and the anterior fundus is adherent to the bladder peritoneal reflection, with the adhesions extending on either side to include the round ligaments.
You begin adhesiolysis in the right lower quadrant to optimize trocar movement. You transect the round ligaments in the mid-position, with dissection extended retroperitoneally on either side to the midline of the lower uterine segment; this opens access to the ascending branch of the uterine vessels. You dissect the intestine free of either pelvic sidewall along the line of demarcation.
Total blood loss is less than 25 mL. The patient is discharged 6 hours after surgery.

CASE: Probable adhesions. Is laparoscopy practical?
A 54-year-old woman complains of perimenopausal bleeding that has not been controlled by hormone therapy, as well as increasing pelvic pain that has caused her to miss work. She wants you to perform hysterectomy to end these problems once and for all.
Aside from these complaints, her history is unremarkable except for a laparotomy at 13 years for a ruptured appendix. Her Pap smear, endometrial biopsy, and pelvic sonogram are negative.
Is she a candidate for laparoscopic hysterectomy?
A patient such as this one, who has a history of laparotomy, is likely to have extensive intra-abdominal adhesions. This pathology increases the risk of bowel injury during surgery—whether it is performed via laparotomy or laparoscopy.
The ability to simplify laparoscopic hysterectomy in a woman who has extensive adhesions requires an understanding of the ways in which adhesions form—in order to lyse them skillfully and avoid creating further adhesions. It also requires special techniques to enter the abdomen, identify the site of attachment, separate adhered structures, and conclude the hysterectomy. Attention to the type of energy that is used also is important.
In this article, we describe these techniques and considerations.
In Part 1 of this article, we discussed techniques that facilitate laparoscopic hysterectomy in a woman who has a large uterus.
Don’t overlook preoperative discussion, preparation
The patient needs to understand the risks and benefits of laparoscopic hysterectomy, particularly when extensive adhesions are likely, as well as the fact that it may be necessary to convert the procedure to laparotomy if the laparoscopic approach proves too difficult. She also needs to understand that conversion to laparotomy does not represent a failure of the procedure but an aim for greater safety.
Because bowel injury is a real risk when the patient has extensive adhesions, mechanical bowel preparation is important. Choose the regimen preferred by the colorectal surgeon likely to be consulted if intraoperative injury occurs.
The operating room (OR) and anesthesia staffs also need to be prepared, and the patient should be positioned for optimal access in the OR. These and other preoperative steps are described in Part 1 of this article and remain the same for the patient who has extensive intra-abdominal adhesions.

Laparoscopic challenges: The large uterus
The authors report no financial relationships relevant to this article.
CASE: Large fibroid uterus. Is laparoscopy feasible?
A 41-year-old woman known to have uterine fibroids consults you after two other gynecologists have recommended abdominal hysterectomy. She weighs 320 lb, stands 5 ft 2 in, and is nulliparous and sexually inactive. Pelvic ultrasonography reveals multiple fibroids approximating 18 weeks’ gestational size. Although she has hypertension and reactive airway disease, these conditions are well controlled by medication. Her Pap smear and endometrial biopsy are negative.
Because her professional commitments limit her time for recovery, she hopes to bypass abdominal hysterectomy in favor of the laparoscopic approach.
Is this desire realistic?
Twenty years have passed since Reich performed the first total laparoscopic hysterectomy,1 but only a small percentage of hysterectomies performed in the United States utilize that approach. In 2003, 12% of 602,457 hysterectomies were done laparoscopically; the rest were performed using the abdominal or vaginal approach (66% and 22%, respectively).2
Yet laparoscopic hysterectomy has much to recommend it. Compared with abdominal hysterectomy, it involves a shorter hospital stay, less blood loss, a speedier return to normal activities, and fewer wound infections.3 Unlike vaginal hysterectomy, it also facilitates intra-abdominal inspection.
Although the opening case represents potentially difficult surgery because of the size of the uterus, the laparoscopic approach is feasible. When the uterus weighs more than 450 g, contains fibroids larger than 6 cm, or exceeds 12 to 14 cm in size,4-7 there is an increased risk of visceral injury, bleeding necessitating transfusion, prolonged operative time, and conversion to laparotomy. This article describes techniques that simplify laparoscopic management when the uterus exceeds 14 weeks’ size. By incorporating these techniques, we have performed laparoscopic hysterectomy in uteri as large as 22 to 24 weeks’ size without increased complications.
In Part 2 of this article, we address techniques that simplify laparoscopy when extensive intra-abdominal adhesions are present.
Why do some surgeons avoid laparoscopy?
Major complications occur in approximately 5% to 6% of women who undergo total laparoscopic hysterectomy.8,9 That is one of the reasons many surgeons who perform laparoscopic procedures revert to the more traditional vaginal or abdominal approach when faced with a potentially difficult hysterectomy. These surgeons cite uteri larger than 14 weeks’ size, extensive intra-abdominal adhesions, and morbid obesity as common indications for a more conservative approach. Others cite the limitations of working with inexperienced surgeons or residents, inadequate laparoscopic instruments, and distorted pelvic anatomy. Still others avoid laparoscopy when the patient has medical problems that preclude use of pneumoperitoneum or a steep Trendelenburg position.
In some cases, laparoscopic hysterectomy is simply not practical. In others, however, such as the presence of a large uterus, it can be achieved with attention to detail, a few key techniques, and proper counseling of the patient.
Success begins preop
All surgical decisions begin with the patient. A comprehensive preoperative discussion of pertinent management options allows both patient and surgeon to proceed with confidence. Easing the patient’s preoperative anxiety is important. It can be achieved by explaining what to expect—not only the normal recovery for laparoscopic hysterectomy, but also the expected recovery if it becomes necessary to convert to laparotomy. If the patient has clear expectations, unexpected outcomes such as conversion are better tolerated. When it comes down to a choice between the surgeon’s ego or patient safety, the patient always wins. Conversion is not failure.
Another important topic to discuss with the patient is the risk of bowel injury. Mechanical bowel preparation is not essential for every patient who undergoes laparoscopic hysterectomy, but the risk of injury to the bowel necessitating colorectal surgical assistance may be heightened in women who have a large uterus or extensive intra-abdominal adhesions. Because of this risk, mechanical bowel preparation with oral polyethylene glycol solution or sodium phosphate should be considered. Most patients prefer the latter.10
What data show about bowel preps
The literature provides conflicting messages about the effectiveness of mechanical bowel preparation in averting additional complications when bowel injury occurs. Nichols and colleagues surveyed 808 active board-certified colorectal surgeons in the United States and Canada in 1995.11 All of the 471 (58%) surgeons who responded reported using some form of mechanical bowel preparation for their elective and emergency colorectal procedures.
Zmora and associates described the difficulty of designing a multicenter study to evaluate the role of mechanical bowel preparation in patient outcome.10 Of the many variables that warrant consideration, surgical technique was the single most important factor influencing surgical outcome.
In a review of evidence supporting the need for prophylactic mechanical bowel preparation prior to elective colorectal surgery, Guenaga and colleagues concluded that this practice is unsupported by the data.12
Bottom line. Given these data, the gynecologist wanting to practice evidence-based medicine should base his or her recommendations about bowel preparation on the preferences of the general or colorectal surgeon who will be called if a bowel injury occurs.
Don’t forget the team
After preparing the patient, prepare your support team—the operating room (OR) and anesthesia staffs. The OR staff should ensure that extra sutures, instruments, and retractors are unopened, in the room, and available in case conversion is necessary. Inform the anesthesia staff of your anticipated surgical time and potential pitfalls. Let them know you will need maximum Trendelenburg position for pelvic exposure, but remain flexible if the patient has trouble with oxygenation and ventilation. Making your anesthesiologist aware of your willingness to work together will benefit both you and your patient immensely.
Preparation continues in the OR
Appropriate patient positioning is key to successful completion of difficult laparoscopic cases. Position the patient’s buttocks several inches beyond the table break to facilitate maximal uterine manipulation, which may be needed for completion of the colpotomy.
Place the patient in the dorsal lithotomy position using Allen stirrups, with the knees flexed at a 90° angle. Keep the knees level with the hips and the hips extended neutrally.
Arm position is important to maximize room for the surgeon alongside the OR table. Space is limited when the patient’s arms are positioned on arm boards. Tucking the arms at the patient’s sides, with the antecubital fossa anterior and the palm cupping the hip, improves the surgical field and secures the patient to the OR table (FIGURE 1). Protect the elbows and hands with cushions.
Place sequential compression devices (on the calf or foot) for the duration of the procedure to minimize the risk of blood stasis and clots that sometimes develop in the legs with prolonged surgical times. Many complex laparoscopic cases last longer than 2 hours.
FIGURE 1 Positioning the patient
Tuck the arms at the patient’s sides, with the antecubital fossa anterior and the palm cupping the hip, to improve the surgical field.
Maximum Trendelenburg position is a must
This positioning is essential for successful anatomic exposure in complex laparoscopic surgical cases. If the patient is positioned securely, maximum Trendelenburg position does not increase the risk of the patient sliding off the OR table, nor does it affect oxygenation in most morbidly obese patients. Rather, it allows the intestines to drop out of the pelvis into the upper abdomen, facilitating visualization and decreasing the risk of bowel injury.
Anesthesia staffers often limit the degree of Trendelenburg position unless the surgeon insists otherwise. Alternating patient position between maximum Trendelenburg for optimal surgical exposure and a less steep angle when patient oxygenation requires it allows the gynecologic surgeon and anesthesiologist to work together in the patient’s best interest.
Video monitor placement is key
It helps determine how efficiently you operate. Use of a single central monitor requires both the surgeon and assistant to turn their heads acutely during prolonged procedures, accelerating their fatigue and potentially increasing the risk of injury. Using two monitors—each placed to allow the surgeon and assistant to maintain neutral head position—minimizes fatigue and its attendant risks.
Entering the abdomen
Abdominal entry poses theoretical obstacles when the patient has a large uterus, but all types of entry remain safe as long as laparoscopic surgical principles are followed scrupulously. We have successfully used traditional Veress needle entry, open laparoscopic entry, and left upper quadrant entry.
Is entry above the umbilicus helpful?
Anecdotal reports suggest a midline port above the umbilicus when the uterus extends above the umbilicus, but we do not alter standard port placement in these cases. By tenting the abdominal wall at the umbilicus, we create adequate distance to achieve pneumoperitoneum and space for directed trocar entry to avoid injury to the uterus. The conventional umbilical primary port allows use of standard-length instruments. The cephalad uterine blood supply (infundibulopelvic ligament vessels or utero-ovarian ligament vessels) remains at or below the level of the umbilicus in almost all of these patients.
Port placement in the patient who has a large uterus is the same as it is for other laparoscopic hysterectomies in our practice. We use an 11-mm trocar at the umbilicus for a 10-mm endoscope. We use the 10-mm endoscope because the light it provides to the surgical field is superior to that of a 5-mm endoscope, and the 10-mm scope is more durable.
We place a 5-mm trocar just above the anterior iliac crest on each side, lateral to the ascending inferior epigastric vessels (FIGURE 2). We place an 11-mm trocar 10 cm medial and cephalad to the lower iliac crest port on the side of the primary surgeon. This trocar serves a dual purpose: It is the primary port for the surgeon, and removal of the trocar sleeve later in the procedure allows for easy insertion of the morcellator.
Some patients will require a fifth port on the side opposite the primary surgeon to allow better access to the uterine blood supply or to facilitate uterine manipulation.
FIGURE 2 Port placement when the uterus is large
A midline umbilical port (A) is possible even when the uterus is large. Other ports include a 5-mm trocar just above the anterior iliac crest on each side (B), and an 11-mm trocar 10 cm medial and cephalad to the lower iliac crest port nearest the primary surgeon (C).
Why an angled scope is superior
Many gynecologists fear laparoscopic surgery in patients who have a large uterus. The reason? Poor visualization of the surgical field. However, the type of endoscope that is used has a bearing on visualization.
Most gynecologists are trained to use a 0° endoscope for laparoscopic surgery. However, when the uterus is large, the 0° scope yields an inadequate field of view, whether the endoscope is placed at the umbilicus or through a lateral port. Critical structures like the vascular bundles, ureters, and even the bladder may be inadequately visualized using the 0° endoscope (FIGURE 3).
Gynecologists routinely use angled scopes in hysteroscopy and cystoscopy, but tend to avoid them in laparoscopy because of difficulty orienting the surgical field. As gynecologists, we readily accept that use of an angled scope in hysteroscopy and cystoscopy requires rotation of the scope while the camera maintains its horizontal position. The same concept applies to laparoscopy.
Use of the angled scope in the abdomen is a two-step process. First, it must be rotated to achieve the desired field of view. Then, as the endoscope is held firmly to maintain this view, the camera head must be rotated on the scope to return the field to a horizontal position.
Many surgeons find this action difficult because they or the assistant are holding the camera in one hand and an instrument in the other. We solve this problem by using a mechanical scope holder to secure the camera and endoscope in the position we desire.
In some cases, the camera head does not attach securely to the eyepiece, and the scope rotates on the camera as soon as it is released. This difficulty arises when the eyepiece of the endoscope is slightly smaller than the camera attachment. The problem is easily solved by placing a small piece of surgical skin closure tape on one edge of the eyepiece, slightly increasing its diameter. The camera attachment then holds the scope securely.
Human scope holders may tire during long cases, causing field drift at critical moments. In contrast, a mechanical scope holder is easily and intermittently adjusted for field of view, producing a steady field of view and minimizing the impact of manual manipulation of the scope on surgical outcome. It also allows the surgeon and first assistant to use two hands while operating.
General surgeons and urologists often use 30° endoscopes. Gynecologists working in the pelvis see better using a 45° scope (FIGURE 3). Most ORs offer a 30° endoscope but do not always have a 45° endoscope available in the instrument room. This is regrettable. Compared with the 30° scope, the 45° instrument provides better visual access to the low lateral uterine blood supply and bladder flap, particularly when the patient has a globular uterus or large, low anterior fibroid. We include both 5-mm and 10-mm 45° endoscopes in our laparoscopic tool chest, and believe they are essential options.
FIGURE 3 The 45° laparoscope provides better visual access

Control the blood supply
Our laparoscopic approach is very similar to our technique for abdominal hysterectomy, beginning with the blood supply. The main blood supply to the uterus enters at only four points. If this blood supply is adequately controlled, morcellation of the large uterus can proceed without excessive blood loss.
Visualization of the blood supply is normally restricted because of tense, taut round ligaments that limit mobility of the large uterus. A simple step to improve mobility is to transect each round ligament in its middle position before addressing the uterine blood supply.
If the ovaries are being conserved, transect the utero-ovarian ligament and tube as close to the ovary as possible with your instrument and technique of choice (electrical or mechanical energy, etc); they all work. Stay close to the ovary to avert bleeding that might otherwise occur when the ascending uterine vascular coils are cut tangentially.
If the ovaries are being removed, transect the infundibulopelvic ligament close to the ovary, being careful not to include ovarian tissue in the pedicle. Use your method of choice, but relieve tension on the pedicle as it is being transected to minimize the risk of pedicle bleeding.
Now, 20% to 40% of the uterine blood supply is controlled, with minimal blood loss.
The key to controlling the remaining blood supply is transecting the ascending vascular bundle as low as possible on either side. The 45° endoscope provides optimal visualization for this part of the procedure. Many times the field of view attained using the 45° endoscope is all that is necessary to facilitate occlusion and transection of these vessels at the level of the internal cervical os.
We commonly use ultrasonic energy to coagulate and cut the ascending vascular bundle. Ultrasonic energy provides excellent hemostasis for this part of the procedure. Again, use the technique of your choice.
Use a laparoscopic “leash”
At times, large broad-ligament fibroids obscure the field of view and access to the ascending vascular bundle. Standard laparoscopic graspers cannot maintain a firm hold on the tissue to improve visibility or access. The solution? A laparoscopic “leash,” first described in 1999 by Tsin and colleagues.13
Giesler extended that concept with a “puppet string” variation to maximize exposure in difficult cases. To apply the “puppet string” technique, using No. 1 Prolene suture, place a large figure-of-eight suture through the tissue to be retracted (FIGURE 4). Bring the suture out of the abdomen adjacent to the trocar sleeve in a location that provides optimal traction. (First, bring the suture through the trocar sleeve. Then remove the trocar sleeve and reinsert it adjacent to the retraction suture.) This secure attachment allows better visualization and greater access to the blood supply at a lower level. It also is possible to manipulate this suture inside the abdomen using traditional graspers to provide reliable repositioning of the uterus. This degree of tissue control improves field of vision and allows the procedure to advance smoothly.
FIGURE 4 A “puppet string” improves access
This secure attachment allows better visualization and greater access to the blood supply at a lower level. Manipulation of this suture inside the abdomen using traditional graspers also helps reposition the uterus.
Morcellation techniques
Once the ascending blood supply has been managed on both sides, morcellation can be performed with minimal blood loss using one of two techniques:
- Amputate the body of the uterus above the level where the blood supply has been interrupted
- Morcellate the uterine body to a point just above the level where the blood supply has been interrupted.
Use basic principles, regardless of the technique chosen
- Hold the morcellator in one hand and a toothed grasper in the other hand to pull tissue into the morcellator. Do not push the morcellator into tissue or you may injure nonvisualized structures on the other side.
- Morcellate tissue in half-moon portions, skimming along the top of the fundus, instead of coring the uterus like an apple; it creates longer strips of tissue and is faster. This technique also allows continuous observation of the active blade, which helps avoid inadvertent injury to tissues behind the blade.
- Attempt morcellation in the anterior abdominal space to avoid injury to blood vessels, ureters, and bowel in the posterior abdominal space. The assistant feeds uterine tissue to the surgeon in the anterior space.
It is essential to control the blood supply to the tissue to be morcellated before morcellation to avoid massive hemorrhage.
Amputating the upper uterine body
Amputation of the large body of the uterus from the lower uterine segment assures complete control of the blood supply and avoids further blood loss during morcellation, but it also poses difficulties. The free uterine mass is held in position by the assistant using only one grasper. If this grasper slips, the mass can be inadvertently released while the morcellator blade is active. If the assistant is also holding the camera, there are no options for stabilizing the free uterine mass. If a mechanical scope holder or second assistant is available to hold the camera, a second trocar port can be placed on the side of the assistant to provide access for a second grasper to stabilize the uterine body during morcellation. The need for a stable uterine mass is important to minimize the risk of injury.
Once the upper body of the uterus has been removed by morcellation, the lower uterine segment and cervix must be removed—using your procedure of choice—to finish the hysterectomy.
Morcellating the upper uterine body
If the uterus remains attached to the cervix, it already has one fixed point of stability. During morcellation, the assistant has one hand available to direct the camera. Blood loss during morcellation of the uterus while it is still attached to the cervix is minimal because the ascending vascular bundles on either side have been interrupted under direct vision.
For greater control of the large uterus, a second port can be placed on the assistant’s side for a second grasper, as described above. Most of the large uterus that is still connected to the cervix can be morcellated in the anterior abdominal space in horizontal fashion, as for the free uterine mass just described.
Uterine manipulation by the assistant keeps the uterus away from critical structures as it is reduced to 8 to 10 weeks’ size. Once this size is attained, resume normal technique for total laparoscopic hysterectomy to separate the remaining tissue from the vagina.
2 types of morcellators in use today
One has a disposable 15-mm blade that attaches to a drive unit adjacent to the OR table (Gynecare-Ethicon Women’s Health and Urology). The other has a sterile, reusable drive unit with a disposable blade (Storz). Both work well on large uteri.
The reusable drive unit has more power to morcellate calcified fibroids and offers a choice between 12-mm, 15-mm, and 20-mm disposable blades for faster morcellation.
Concluding the procedure
Chips of fibroid and uterine tissue created during morcellation often remain in the pelvis after the uterus has been removed. Place them in a 10-cm specimen-collection bag and extract it through the vagina after removal of the residual uterus and cervix. This is faster and easier than recovering them one at a time with the gall bladder stone scoop through a trocar port. The value of the OR time saved with use of the specimen-collection bag is significantly greater than that of the disposable collection device.
CASE RESOLVED
You perform total laparoscopic hysterectomy and find 6-cm fibroids in both broad ligament areas and over the cervical–vaginal junction on the left. You use a “puppet string” to apply directed traction to the fibroids to simplify their extraction. The 45° endoscope allows clear visualization of the ascending vascular bundle on both sides, and the mechanical scope holder allows a fixed field of view for the meticulous dissection required to remove the broad-ligament fibroids.
You morcellate the entire 663-g uterus and remove it in pieces through the abdominal wall. The extensive morcellation required, coupled with technical issues related to the patient’s morbid obesity, prolong the procedure to more than 4 hours.
Postoperatively, the patient voids without a catheter, walks around the nursing unit, and eats half a sandwich within 4 hours. She is discharged home in less than 24 hours and is able to drive 4 days after her surgery.

CASE: Large fibroid uterus. Is laparoscopy feasible?
A 41-year-old woman known to have uterine fibroids consults you after two other gynecologists have recommended abdominal hysterectomy. She weighs 320 lb, stands 5 ft 2 in, and is nulliparous and sexually inactive. Pelvic ultrasonography reveals multiple fibroids approximating 18 weeks’ gestational size. Although she has hypertension and reactive airway disease, these conditions are well controlled by medication. Her Pap smear and endometrial biopsy are negative.
Because her professional commitments limit her time for recovery, she hopes to bypass abdominal hysterectomy in favor of the laparoscopic approach.
Is this desire realistic?
Twenty years have passed since Reich performed the first total laparoscopic hysterectomy,1 but only a small percentage of hysterectomies performed in the United States utilize that approach. In 2003, 12% of 602,457 hysterectomies were done laparoscopically; the rest were performed using the abdominal or vaginal approach (66% and 22%, respectively).2
Yet laparoscopic hysterectomy has much to recommend it. Compared with abdominal hysterectomy, it involves a shorter hospital stay, less blood loss, a speedier return to normal activities, and fewer wound infections.3 Unlike vaginal hysterectomy, it also facilitates intra-abdominal inspection.
Although the opening case represents potentially difficult surgery because of the size of the uterus, the laparoscopic approach is feasible. When the uterus weighs more than 450 g, contains fibroids larger than 6 cm, or exceeds 12 to 14 cm in size,4-7 there is an increased risk of visceral injury, bleeding necessitating transfusion, prolonged operative time, and conversion to laparotomy. This article describes techniques that simplify laparoscopic management when the uterus exceeds 14 weeks’ size. By incorporating these techniques, we have performed laparoscopic hysterectomy in uteri as large as 22 to 24 weeks’ size without increased complications.
In Part 2 of this article, we address techniques that simplify laparoscopy when extensive intra-abdominal adhesions are present.
Why do some surgeons avoid laparoscopy?
Major complications occur in approximately 5% to 6% of women who undergo total laparoscopic hysterectomy.8,9 That is one of the reasons many surgeons who perform laparoscopic procedures revert to the more traditional vaginal or abdominal approach when faced with a potentially difficult hysterectomy. These surgeons cite uteri larger than 14 weeks’ size, extensive intra-abdominal adhesions, and morbid obesity as common indications for a more conservative approach. Others cite the limitations of working with inexperienced surgeons or residents, inadequate laparoscopic instruments, and distorted pelvic anatomy. Still others avoid laparoscopy when the patient has medical problems that preclude use of pneumoperitoneum or a steep Trendelenburg position.
In some cases, laparoscopic hysterectomy is simply not practical. In others, however, such as the presence of a large uterus, it can be achieved with attention to detail, a few key techniques, and proper counseling of the patient.
Success begins preop
All surgical decisions begin with the patient. A comprehensive preoperative discussion of pertinent management options allows both patient and surgeon to proceed with confidence. Easing the patient’s preoperative anxiety is important. It can be achieved by explaining what to expect—not only the normal recovery for laparoscopic hysterectomy, but also the expected recovery if it becomes necessary to convert to laparotomy. If the patient has clear expectations, unexpected outcomes such as conversion are better tolerated. When it comes down to a choice between the surgeon’s ego or patient safety, the patient always wins. Conversion is not failure.
Another important topic to discuss with the patient is the risk of bowel injury. Mechanical bowel preparation is not essential for every patient who undergoes laparoscopic hysterectomy, but the risk of injury to the bowel necessitating colorectal surgical assistance may be heightened in women who have a large uterus or extensive intra-abdominal adhesions. Because of this risk, mechanical bowel preparation with oral polyethylene glycol solution or sodium phosphate should be considered. Most patients prefer the latter.10
What data show about bowel preps
The literature provides conflicting messages about the effectiveness of mechanical bowel preparation in averting additional complications when bowel injury occurs. Nichols and colleagues surveyed 808 active board-certified colorectal surgeons in the United States and Canada in 1995.11 All of the 471 (58%) surgeons who responded reported using some form of mechanical bowel preparation for their elective and emergency colorectal procedures.
Zmora and associates described the difficulty of designing a multicenter study to evaluate the role of mechanical bowel preparation in patient outcome.10 Of the many variables that warrant consideration, surgical technique was the single most important factor influencing surgical outcome.
In a review of evidence supporting the need for prophylactic mechanical bowel preparation prior to elective colorectal surgery, Guenaga and colleagues concluded that this practice is unsupported by the data.12
Bottom line. Given these data, the gynecologist wanting to practice evidence-based medicine should base his or her recommendations about bowel preparation on the preferences of the general or colorectal surgeon who will be called if a bowel injury occurs.
Don’t forget the team
After preparing the patient, prepare your support team—the operating room (OR) and anesthesia staffs. The OR staff should ensure that extra sutures, instruments, and retractors are unopened, in the room, and available in case conversion is necessary. Inform the anesthesia staff of your anticipated surgical time and potential pitfalls. Let them know you will need maximum Trendelenburg position for pelvic exposure, but remain flexible if the patient has trouble with oxygenation and ventilation. Making your anesthesiologist aware of your willingness to work together will benefit both you and your patient immensely.
Preparation continues in the OR
Appropriate patient positioning is key to successful completion of difficult laparoscopic cases. Position the patient’s buttocks several inches beyond the table break to facilitate maximal uterine manipulation, which may be needed for completion of the colpotomy.
Place the patient in the dorsal lithotomy position using Allen stirrups, with the knees flexed at a 90° angle. Keep the knees level with the hips and the hips extended neutrally.
Arm position is important to maximize room for the surgeon alongside the OR table. Space is limited when the patient’s arms are positioned on arm boards. Tucking the arms at the patient’s sides, with the antecubital fossa anterior and the palm cupping the hip, improves the surgical field and secures the patient to the OR table (FIGURE 1). Protect the elbows and hands with cushions.
Place sequential compression devices (on the calf or foot) for the duration of the procedure to minimize the risk of blood stasis and clots that sometimes develop in the legs with prolonged surgical times. Many complex laparoscopic cases last longer than 2 hours.
FIGURE 1 Positioning the patient
Tuck the arms at the patient’s sides, with the antecubital fossa anterior and the palm cupping the hip, to improve the surgical field.
Maximum Trendelenburg position is a must
This positioning is essential for successful anatomic exposure in complex laparoscopic surgical cases. If the patient is positioned securely, maximum Trendelenburg position does not increase the risk of the patient sliding off the OR table, nor does it affect oxygenation in most morbidly obese patients. Rather, it allows the intestines to drop out of the pelvis into the upper abdomen, facilitating visualization and decreasing the risk of bowel injury.
Anesthesia staffers often limit the degree of Trendelenburg position unless the surgeon insists otherwise. Alternating patient position between maximum Trendelenburg for optimal surgical exposure and a less steep angle when patient oxygenation requires it allows the gynecologic surgeon and anesthesiologist to work together in the patient’s best interest.
Video monitor placement is key
It helps determine how efficiently you operate. Use of a single central monitor requires both the surgeon and assistant to turn their heads acutely during prolonged procedures, accelerating their fatigue and potentially increasing the risk of injury. Using two monitors—each placed to allow the surgeon and assistant to maintain neutral head position—minimizes fatigue and its attendant risks.
Entering the abdomen
Abdominal entry poses theoretical obstacles when the patient has a large uterus, but all types of entry remain safe as long as laparoscopic surgical principles are followed scrupulously. We have successfully used traditional Veress needle entry, open laparoscopic entry, and left upper quadrant entry.
Is entry above the umbilicus helpful?
Anecdotal reports suggest a midline port above the umbilicus when the uterus extends above the umbilicus, but we do not alter standard port placement in these cases. By tenting the abdominal wall at the umbilicus, we create adequate distance to achieve pneumoperitoneum and space for directed trocar entry to avoid injury to the uterus. The conventional umbilical primary port allows use of standard-length instruments. The cephalad uterine blood supply (infundibulopelvic ligament vessels or utero-ovarian ligament vessels) remains at or below the level of the umbilicus in almost all of these patients.
Port placement in the patient who has a large uterus is the same as it is for other laparoscopic hysterectomies in our practice. We use an 11-mm trocar at the umbilicus for a 10-mm endoscope. We use the 10-mm endoscope because the light it provides to the surgical field is superior to that of a 5-mm endoscope, and the 10-mm scope is more durable.
We place a 5-mm trocar just above the anterior iliac crest on each side, lateral to the ascending inferior epigastric vessels (FIGURE 2). We place an 11-mm trocar 10 cm medial and cephalad to the lower iliac crest port on the side of the primary surgeon. This trocar serves a dual purpose: It is the primary port for the surgeon, and removal of the trocar sleeve later in the procedure allows for easy insertion of the morcellator.
Some patients will require a fifth port on the side opposite the primary surgeon to allow better access to the uterine blood supply or to facilitate uterine manipulation.
FIGURE 2 Port placement when the uterus is large
A midline umbilical port (A) is possible even when the uterus is large. Other ports include a 5-mm trocar just above the anterior iliac crest on each side (B), and an 11-mm trocar 10 cm medial and cephalad to the lower iliac crest port nearest the primary surgeon (C).
Why an angled scope is superior
Many gynecologists fear laparoscopic surgery in patients who have a large uterus. The reason? Poor visualization of the surgical field. However, the type of endoscope that is used has a bearing on visualization.
Most gynecologists are trained to use a 0° endoscope for laparoscopic surgery. However, when the uterus is large, the 0° scope yields an inadequate field of view, whether the endoscope is placed at the umbilicus or through a lateral port. Critical structures like the vascular bundles, ureters, and even the bladder may be inadequately visualized using the 0° endoscope (FIGURE 3).
Gynecologists routinely use angled scopes in hysteroscopy and cystoscopy, but tend to avoid them in laparoscopy because of difficulty orienting the surgical field. As gynecologists, we readily accept that use of an angled scope in hysteroscopy and cystoscopy requires rotation of the scope while the camera maintains its horizontal position. The same concept applies to laparoscopy.
Use of the angled scope in the abdomen is a two-step process. First, it must be rotated to achieve the desired field of view. Then, as the endoscope is held firmly to maintain this view, the camera head must be rotated on the scope to return the field to a horizontal position.
Many surgeons find this action difficult because they or the assistant are holding the camera in one hand and an instrument in the other. We solve this problem by using a mechanical scope holder to secure the camera and endoscope in the position we desire.
In some cases, the camera head does not attach securely to the eyepiece, and the scope rotates on the camera as soon as it is released. This difficulty arises when the eyepiece of the endoscope is slightly smaller than the camera attachment. The problem is easily solved by placing a small piece of surgical skin closure tape on one edge of the eyepiece, slightly increasing its diameter. The camera attachment then holds the scope securely.
Human scope holders may tire during long cases, causing field drift at critical moments. In contrast, a mechanical scope holder is easily and intermittently adjusted for field of view, producing a steady field of view and minimizing the impact of manual manipulation of the scope on surgical outcome. It also allows the surgeon and first assistant to use two hands while operating.
General surgeons and urologists often use 30° endoscopes. Gynecologists working in the pelvis see better using a 45° scope (FIGURE 3). Most ORs offer a 30° endoscope but do not always have a 45° endoscope available in the instrument room. This is regrettable. Compared with the 30° scope, the 45° instrument provides better visual access to the low lateral uterine blood supply and bladder flap, particularly when the patient has a globular uterus or large, low anterior fibroid. We include both 5-mm and 10-mm 45° endoscopes in our laparoscopic tool chest, and believe they are essential options.
FIGURE 3 The 45° laparoscope provides better visual access
(A) 0° scope, uterus midline: Right broad ligament view obstructed. (B) 0° scope, uterus to left: Right broad ligament view still obstructed. (C) 45° scope, uterus midline: Right broad ligament view improved. (D) 45° scope, uterus to left: Right broad ligament view optimal.
Control the blood supply
Our laparoscopic approach is very similar to our technique for abdominal hysterectomy, beginning with the blood supply. The main blood supply to the uterus enters at only four points. If this blood supply is adequately controlled, morcellation of the large uterus can proceed without excessive blood loss.
Visualization of the blood supply is normally restricted because of tense, taut round ligaments that limit mobility of the large uterus. A simple step to improve mobility is to transect each round ligament in its middle position before addressing the uterine blood supply.
If the ovaries are being conserved, transect the utero-ovarian ligament and tube as close to the ovary as possible with your instrument and technique of choice (electrical or mechanical energy, etc); they all work. Stay close to the ovary to avert bleeding that might otherwise occur when the ascending uterine vascular coils are cut tangentially.
If the ovaries are being removed, transect the infundibulopelvic ligament close to the ovary, being careful not to include ovarian tissue in the pedicle. Use your method of choice, but relieve tension on the pedicle as it is being transected to minimize the risk of pedicle bleeding.
Now, 20% to 40% of the uterine blood supply is controlled, with minimal blood loss.
The key to controlling the remaining blood supply is transecting the ascending vascular bundle as low as possible on either side. The 45° endoscope provides optimal visualization for this part of the procedure. Many times the field of view attained using the 45° endoscope is all that is necessary to facilitate occlusion and transection of these vessels at the level of the internal cervical os.

Most of the large uterus that is still connected to the cervix can be morcellated in the anterior abdominal space in horizontal fashion, as for the free uterine mass just described.
Uterine manipulation by the assistant keeps the uterus away from critical structures as it is reduced to 8 to 10 weeks’ size. Once this size is attained, resume normal technique for total laparoscopic hysterectomy to separate the remaining tissue from the vagina.

CASE: Large fibroid uterus. Is laparoscopy feasible?
A 41-year-old woman known to have uterine fibroids consults you after two other gynecologists have recommended abdominal hysterectomy.

When the uterus weighs more than 450 g, contains fibroids larger than 6 cm, or exceeds 12 to 14 cm in size,4-7 there is an increased risk of visceral injury, bleeding necessitating transfusion, prolonged operative time, and conversion to laparotomy. This article describes techniques that simplify laparoscopic management when the uterus exceeds 14 weeks’ size. By incorporating these techniques, we have performed laparoscopic hysterectomy in uteri as large as 22 to 24 weeks’ size without increased complications.
In Part 2 of this article, we address techniques that simplify laparoscopy when extensive intra-abdominal adhesions are present.
Why do some surgeons avoid laparoscopy?
Major complications occur in approximately 5% to 6% of women who undergo total laparoscopic hysterectomy.8,9 That is one of the reasons many surgeons who perform laparoscopic procedures revert to the more traditional vaginal or abdominal approach when faced with a potentially difficult hysterectomy. These surgeons cite uteri larger than 14 weeks’ size, extensive intra-abdominal adhesions, and morbid obesity as common indications for a more conservative approach. Others cite the limitations of working with inexperienced surgeons or residents, inadequate laparoscopic instruments, and distorted pelvic anatomy. Still others avoid laparoscopy when the patient has medical problems that preclude use of pneumoperitoneum or a steep Trendelenburg position.
In some cases, laparoscopic hysterectomy is simply not practical. In others, however, such as the presence of a large uterus, it can be achieved with attention to detail, a few key techniques, and proper counseling of the patient.
Success begins preop
All surgical decisions begin with the patient. A comprehensive preoperative discussion of pertinent management options allows both patient and surgeon to proceed with confidence. Easing the patient’s preoperative anxiety is important. It can be achieved by explaining what to expect—not only the normal recovery for laparoscopic hysterectomy, but also the expected recovery if it becomes necessary to convert to laparotomy. If the patient has clear expectations, unexpected outcomes such as conversion are better tolerated. When it comes down to a choice between the surgeon’s ego or patient safety, the patient always wins. Conversion is not failure.
Another important topic to discuss with the patient is the risk of bowel injury. Mechanical bowel preparation is not essential for every patient who undergoes laparoscopic hysterectomy, but the risk of injury to the bowel necessitating colorectal surgical assistance may be heightened in women who have a large uterus or extensive intra-abdominal adhesions. Because of this risk, mechanical bowel preparation with oral polyethylene glycol solution or sodium phosphate should be considered. Most patients prefer the latter.10
What data show about bowel preps
The literature provides conflicting messages about the effectiveness of mechanical bowel preparation in averting additional complications when bowel injury occurs. Nichols and colleagues surveyed 808 active board-certified colorectal surgeons in the United States and Canada in 1995.11 All of the 471 (58%) surgeons who responded reported using some form of mechanical bowel preparation for their elective and emergency colorectal procedures.
Zmora and associates described the difficulty of designing a multicenter study to evaluate the role of mechanical bowel preparation in patient outcome.10 Of the many variables that warrant consideration, surgical technique was the single most important factor influencing surgical outcome.
In a review of evidence supporting the need for prophylactic mechanical bowel preparation prior to elective colorectal surgery, Guenaga and colleagues concluded that this practice is unsupported by the data.12
Bottom line. Given these data, the gynecologist wanting to practice evidence-based medicine should base his or her recommendations about bowel preparation on the preferences of the general or colorectal surgeon who will be called if a bowel injury occurs.
Don’t forget the team
After preparing the patient, prepare your support team—the operating room (OR) and anesthesia staffs. The OR staff should ensure that extra sutures, instruments, and retractors are unopened, in the room, and available in case conversion is necessary. Inform the anesthesia staff of your anticipated surgical time and potential pitfalls. Let them know you will need maximum Trendelenburg position for pelvic exposure, but remain flexible if the patient has trouble with oxygenation and ventilation. Making your anesthesiologist aware of your willingness to work together will benefit both you and your patient immensely.
Preparation continues in the OR
Appropriate patient positioning is key to successful completion of difficult laparoscopic cases. Position the patient’s buttocks several inches beyond the table break to facilitate maximal uterine manipulation, which may be needed for completion of the colpotomy.
Place the patient in the dorsal lithotomy position using Allen stirrups, with the knees flexed at a 90° angle. Keep the knees level with the hips and the hips extended neutrally.
Arm position is important to maximize room for the surgeon alongside the OR table. Space is limited when the patient’s arms are positioned on arm boards. Tucking the arms at the patient’s sides, with the antecubital fossa anterior and the palm cupping the hip, improves the surgical field and secures the patient to the OR table (FIGURE 1). Protect the elbows and hands with cushions.
Place sequential compression devices (on the calf or foot) for the duration of the procedure to minimize the risk of blood stasis and clots that sometimes develop in the legs with prolonged surgical times. Many complex laparoscopic cases last longer than 2 hours.
FIGURE 1 Positioning the patient
Tuck the arms at the patient’s sides, with the antecubital fossa anterior and the palm cupping the hip, to improve the surgical field.
Maximum Trendelenburg position is a must
This positioning is essential for successful anatomic exposure in complex laparoscopic surgical cases. If the patient is positioned securely, maximum Trendelenburg position does not increase the risk of the patient sliding off the OR table, nor does it affect oxygenation in most morbidly obese patients. Rather, it allows the intestines to drop out of the pelvis into the upper abdomen, facilitating visualization and decreasing the risk of bowel injury.
Anesthesia staffers often limit the degree of Trendelenburg position unless the surgeon insists otherwise. Alternating patient position between maximum Trendelenburg for optimal surgical exposure and a less steep angle when patient oxygenation requires it allows the gynecologic surgeon and anesthesiologist to work together in the patient’s best interest.
Video monitor placement is key
It helps determine how efficiently you operate. Use of a single central monitor requires both the surgeon and assistant to turn their heads acutely during prolonged procedures, accelerating their fatigue and potentially increasing the risk of injury. Using two monitors—each placed to allow the surgeon and assistant to maintain neutral head position—minimizes fatigue and its attendant risks.
Entering the abdomen
Abdominal entry poses theoretical obstacles when the patient has a large uterus, but all types of entry remain safe as long as laparoscopic surgical principles are followed scrupulously. We have successfully used traditional Veress needle entry, open laparoscopic entry, and left upper quadrant entry.
Is entry above the umbilicus helpful?
Anecdotal reports suggest a midline port above the umbilicus when the uterus extends above the umbilicus, but we do not alter standard port placement in these cases. By tenting the abdominal wall at the umbilicus, we create adequate distance to achieve pneumoperitoneum and space for directed trocar entry to avoid injury to the uterus. The conventional umbilical primary port allows use of standard-length instruments. The cephalad uterine blood supply (infundibulopelvic ligament vessels or utero-ovarian ligament vessels) remains at or below the level of the umbilicus in almost all of these patients.
Port placement in the patient who has a large uterus is the same as it is for other laparoscopic hysterectomies in our practice. We use an 11-mm trocar at the umbilicus for a 10-mm endoscope. We use the 10-mm endoscope because the light it provides to the surgical field is superior to that of a 5-mm endoscope, and the 10-mm scope is more durable.
We place a 5-mm trocar just above the anterior iliac crest on each side, lateral to the ascending inferior epigastric vessels (FIGURE 2). We place an 11-mm trocar 10 cm medial and cephalad to the lower iliac crest port on the side of the primary surgeon. This trocar serves a dual purpose: It is the primary port for the surgeon, and removal of the trocar sleeve later in the procedure allows for easy insertion of the morcellator.
Some patients will require a fifth port on the side opposite the primary surgeon to allow better access to the uterine blood supply or to facilitate uterine manipulation.
FIGURE 2 Port placement when the uterus is large
A midline umbilical port (A) is possible even when the uterus is large. Other ports include a 5-mm trocar just above the anterior iliac crest on each side (B), and an 11-mm trocar 10 cm medial and cephalad to the lower iliac crest port nearest the primary surgeon (C).
Why an angled scope is superior
Many gynecologists fear laparoscopic surgery in patients who have a large uterus. The reason? Poor visualization of the surgical field. However, the type of endoscope that is used has a bearing on visualization.
Most gynecologists are trained to use a 0° endoscope for laparoscopic surgery. However, when the uterus is large, the 0° scope yields an inadequate field of view, whether the endoscope is placed at the umbilicus or through a lateral port. Critical structures like the vascular bundles, ureters, and even the bladder may be inadequately visualized using the 0° endoscope (FIGURE 3).
Gynecologists routinely use angled scopes in hysteroscopy and cystoscopy, but tend to avoid them in laparoscopy because of difficulty orienting the surgical field. As gynecologists, we readily accept that use of an angled scope in hysteroscopy and cystoscopy requires rotation of the scope while the camera maintains its horizontal position. The same concept applies to laparoscopy.
Use of the angled scope in the abdomen is a two-step process. First, it must be rotated to achieve the desired field of view. Then, as the endoscope is held firmly to maintain this view, the camera head must be rotated on the scope to return the field to a horizontal position.
Many surgeons find this action difficult because they or the assistant are holding the camera in one hand and an instrument in the other. We solve this problem by using a mechanical scope holder to secure the camera and endoscope in the position we desire.
In some cases, the camera head does not attach securely to the eyepiece, and the scope rotates on the camera as soon as it is released. This difficulty arises when the eyepiece of the endoscope is slightly smaller than the camera attachment. The problem is easily solved by placing a small piece of surgical skin closure tape on one edge of the eyepiece, slightly increasing its diameter. The camera attachment then holds the scope securely.
Human scope holders may tire during long cases, causing field drift at critical moments. In contrast, a mechanical scope holder is easily and intermittently adjusted for field of view, producing a steady field of view and minimizing the impact of manual manipulation of the scope on surgical outcome. It also allows the surgeon and first assistant to use two hands while operating.
General surgeons and urologists often use 30° endoscopes. Gynecologists working in the pelvis see better using a 45° scope (FIGURE 3). Most ORs offer a 30° endoscope but do not always have a 45° endoscope available in the instrument room. This is regrettable. Compared with the 30° scope, the 45° instrument provides better visual access to the low lateral uterine blood supply and bladder flap, particularly when the patient has a globular uterus or large, low anterior fibroid. We include both 5-mm and 10-mm 45° endoscopes in our laparoscopic tool chest, and believe they are essential options.
FIGURE 3 The 45° laparoscope provides better visual access
(A) 0° scope, uterus midline: Right broad ligament view obstructed. (B) 0° scope, uterus to left: Right broad ligament view still obstructed. (C) 45° scope, uterus midline: Right broad ligament view improved. (D) 45° scope, uterus to left: Right broad ligament view optimal.
Control the blood supply
Our laparoscopic approach is very similar to our technique for abdominal hysterectomy, beginning with the blood supply. The main blood supply to the uterus enters at only four points. If this blood supply is adequately controlled, morcellation of the large uterus can proceed without excessive blood loss.
Visualization of the blood supply is normally restricted because of tense, taut round ligaments that limit mobility of the large uterus. A simple step to improve mobility is to transect each round ligament in its middle position before addressing the uterine blood supply.
If the ovaries are being conserved, transect the utero-ovarian ligament and tube as close to the ovary as possible with your instrument and technique of choice (electrical or mechanical energy, etc); they all work. Stay close to the ovary to avert bleeding that might otherwise occur when the ascending uterine vascular coils are cut tangentially.
If the ovaries are being removed, transect the infundibulopelvic ligament close to the ovary, being careful not to include ovarian tissue in the pedicle. Use your method of choice, but relieve tension on the pedicle as it is being transected to minimize the risk of pedicle bleeding.
Now, 20% to 40% of the uterine blood supply is controlled, with minimal blood loss.
The key to controlling the remaining blood supply is transecting the ascending vascular bundle as low as possible on either side. The 45° endoscope provides optimal visualization for this part of the procedure. Many times the field of view attained using the 45° endoscope is all that is necessary to facilitate occlusion and transection of these vessels at the level of the internal cervical os.
We commonly use ultrasonic energy to coagulate and cut the ascending vascular bundle. Ultrasonic energy provides excellent hemostasis for this part of the procedure. Again, use the technique of your choice.
Use a laparoscopic “leash”
At times, large broad-ligament fibroids obscure the field of view and access to the ascending vascular bundle. Standard laparoscopic graspers cannot maintain a firm hold on the tissue to improve visibility or access. The solution? A laparoscopic “leash,” first described in 1999 by Tsin and colleagues.13
Giesler extended that concept with a “puppet string” variation to maximize exposure in difficult cases. To apply the “puppet string” technique, using No. 1 Prolene suture, place a large figure-of-eight suture through the tissue to be retracted (FIGURE 4). Bring the suture out of the abdomen adjacent to the trocar sleeve in a location that provides optimal traction. (First, bring the suture through the trocar sleeve. Then remove the trocar sleeve and reinsert it adjacent to the retraction suture.) This secure attachment allows better visualization and greater access to the blood supply at a lower level. It also is possible to manipulate this suture inside the abdomen using traditional graspers to provide reliable repositioning of the uterus. This degree of tissue control improves field of vision and allows the procedure to advance smoothly.
FIGURE 4 A “puppet string” improves access
This secure attachment allows better visualization and greater access to the blood supply at a lower level. Manipulation of this suture inside the abdomen using traditional graspers also helps reposition the uterus.
Morcellation techniques
Once the ascending blood supply has been managed on both sides, morcellation can be performed with minimal blood loss using one of two techniques:
- Amputate the body of the uterus above the level where the blood supply has been interrupted
- Morcellate the uterine body to a point just above the level where the blood supply has been interrupted.
Use basic principles, regardless of the technique chosen
- Hold the morcellator in one hand and a toothed grasper in the other hand to pull tissue into the morcellator. Do not push the morcellator into tissue or you may injure nonvisualized structures on the other side.
- Morcellate tissue in half-moon portions, skimming along the top of the fundus, instead of coring the uterus like an apple; it creates longer strips of tissue and is faster. This technique also allows continuous observation of the active blade, which helps avoid inadvertent injury to tissues behind the blade.
- Attempt morcellation in the anterior abdominal space to avoid injury to blood vessels, ureters, and bowel in the posterior abdominal space. The assistant feeds uterine tissue to the surgeon in the anterior space.
It is essential to control the blood supply to the tissue to be morcellated before morcellation to avoid massive hemorrhage.
Amputating the upper uterine body
Amputation of the large body of the uterus from the lower uterine segment assures complete control of the blood supply and avoids further blood loss during morcellation, but it also poses difficulties. The free uterine mass is held in position by the assistant using only one grasper. If this grasper slips, the mass can be inadvertently released while the morcellator blade is active. If the assistant is also holding the camera, there are no options for stabilizing the free uterine mass. If a mechanical scope holder or second assistant is available to hold the camera, a second trocar port can be placed on the side of the assistant to provide access for a second grasper to stabilize the uterine body during morcellation. The need for a stable uterine mass is important to minimize the risk of injury.
Once the upper body of the uterus has been removed by morcellation, the lower uterine segment and cervix must be removed—using your procedure of choice—to finish the hysterectomy.
Morcellating the upper uterine body
If the uterus remains attached to the cervix, it already has one fixed point of stability. During morcellation, the assistant has one hand available to direct the camera. Blood loss during morcellation of the uterus while it is still attached to the cervix is minimal because the ascending vascular bundles on either side have been interrupted under direct vision.
For greater control of the large uterus, a second port can be placed on the assistant’s side for a second grasper, as described above. Most of the large uterus that is still connected to the cervix can be morcellated in the anterior abdominal space in horizontal fashion, as for the free uterine mass just described.
Uterine manipulation by the assistant keeps the uterus away from critical structures as it is reduced to 8 to 10 weeks’ size. Once this size is attained, resume normal technique for total laparoscopic hysterectomy to separate the remaining tissue from the vagina.
2 types of morcellators in use today
One has a disposable 15-mm blade that attaches to a drive unit adjacent to the OR table (Gynecare-Ethicon Women’s Health and Urology). The other has a sterile, reusable drive unit with a disposable blade (Storz). Both work well on large uteri.
The reusable drive unit has more power to morcellate calcified fibroids and offers a choice between 12-mm, 15-mm, and 20-mm disposable blades for faster morcellation.
Concluding the procedure
Chips of fibroid and uterine tissue created during morcellation often remain in the pelvis after the uterus has been removed. Place them in a 10-cm specimen-collection bag and extract it through the vagina after removal of the residual uterus and cervix. This is faster and easier than recovering them one at a time with the gall bladder stone scoop through a trocar port. The value of the OR time saved with use of the specimen-collection bag is significantly greater than that of the disposable collection device.
CASE RESOLVED
You perform total laparoscopic hysterectomy and find 6-cm fibroids in both broad ligament areas and over the cervical–vaginal junction on the left. You use a “puppet string” to apply directed traction to the fibroids to simplify their extraction. The 45° endoscope allows clear visualization of the ascending vascular bundle on both sides, and the mechanical scope holder allows a fixed field of view for the meticulous dissection required to remove the broad-ligament fibroids.
You morcellate the entire 663-g uterus and remove it in pieces through the abdominal wall. The extensive morcellation required, coupled with technical issues related to the patient’s morbid obesity, prolong the procedure to more than 4 hours.
Postoperatively, the patient voids without a catheter, walks around the nursing unit, and eats half a sandwich within 4 hours. She is discharged home in less than 24 hours and is able to drive 4 days after her surgery.

How to avoid injury to bowel during laparoscopy
The author reports no financial relationships relevant to this article.
CASE Postoperative abdominal pain. Is it gastroenteritis?
R.B., 35 years old, undergoes laparoscopic adhesiolysis for abdominal pain. Previously, she underwent exploratory laparotomy for a ruptured tubal pregnancy and, in separate operations, right oophorectomy via laparotomy for a ruptured corpus luteum cyst and diagnostic laparoscopy.
During the current surgery, extensive adhesions are observed, including interloop intestinal adhesions. The adhesions are lysed using monopolar scissors and a needle electrode, and R.B. is discharged home the same day.
Later that day and the next day, R.B. complains of abdominal pain that does not respond to prescribed analgesics, as well as nausea and vomiting. A nurse practitioner takes her call and prescribes a stronger analgesic, an antiemetic, and an antibiotic.
The following day, the patient’s husband telephones the treating gynecologist to report that his wife is still experiencing severe pain and nausea. He is told to bring her to the office, where she is described as having mild lower abdominal tenderness and mild rebound. An abdominal radiograph shows air-fluid levels and distended bowel. The gynecologist determines that the patient is experiencing gastroenteritis.
On postop day 3, R.B. continues to suffer from severe abdominal pain, nausea, and vomiting, and is unable to get out of bed. Her husband takes her to the emergency room at another hospital, where she is found to have diffuse peritonitis, absent bowel sounds, and:
- temperature, 101.8°F
- heart rate, 130/min
- respiratory rate, 24/min
- blood pressure, 90/60 mm Hg
- white blood cell (WBC) count, 21.5 × 103/μL
- x-ray showing free air.
A general surgeon performs an exploratory laparotomy and finds foul-smelling abdominal fluid, 200 to 300 mL of pus, and a 1-cm perforation of the sigmoid colon. He performs sigmoid colon resection and a left-colon colostomy. A second laparotomy is necessary to drain a subphrenic abscess.
Four months later, the colostomy is taken down and bowel continuity is established.
Subsequently, the patient experiences episodes of gaseous and fecal incontinence, which are thought to be secondary to nerve damage. A ventral hernia is also diagnosed.
Could this outcome have been avoided?
No physician would wish a major complication of surgery upon any patient. Yet, sometimes, preventive efforts fall short of the goal or the physician is slow to suspect injury when the patient experiences postoperative abdominal pain and other symptoms. Intestinal injury may not be common during laparoscopy, but it is certainly not rare. And the longer diagnosis is delayed, the greater the risk of sepsis, even death.
Recognizing the limitations of laparoscopic surgery is a first step toward reducing the complication rate.1,2 The ability to determine when laparotomy would better serve the patient’s interests is also critical, and prompt diagnosis and repair of any complication that does occur will ensure and speed the patient’s recovery.
The most serious complications associated with diagnostic and operative laparoscopy are major vessel and intestinal injuries. Both types of injury significantly raise the risk of mortality, which ranges from 2% to 23%.3,4 The overall risk of injury to the gastrointestinal tract averages 1.6 to 2.0 for every 1,000 cases. The risk of major vessel injury averages 0.5 for every 1,000 cases.5-9
In an earlier article for OBG Management, I reviewed vascular injury during laparoscopy.10 In Part 1 of this article, I focus on ways to avoid intestinal injury.In Part 2 , I outline strategies to identify it in a timely manner when it does occur.
- Avoid laparoscopy when severe adhesions are anticipated—such as when the patient has a history of multiple laparotomies, or when significant adhesions have been documented.
- Be aware that laparoscopy carries additional risks beyond those of the primary surgical procedure, owing to factors peculiar to endoscopic technique and instrumentation.
- Consider open laparoscopy or insert the primary trocar at an alternative location, such as the left upper quadrant, when the patient has a history of laparotomy.
- Avoid blunt dissection for anything other than mild (filmy) adhesions. Sharp dissection associated with hydrodissection is the safest method of adhesiolysis. Clear visualization of the operative site is the sine qua non for precise dissection.
- Avoid monopolar electrosurgical devices for laparoscopic surgery whenever possible. Also remember that bipolar and ultrasonic devices can cause thermal injury by heat conduction as well as by direct application. Laser energy will continue beyond the target unless provision is made to absorb the residual energy.
- At the conclusion of any laparoscopic procedure, especially after adhesiolysis or bowel dissection, inspect the intestines and include the details in the operative report.
- After any laparoscopic procedure, if the patient does not improve steadily, the first presumptive diagnosis to be excluded is injury secondary to the procedure or technique.
- The major symptom of intestinal perforation is abdominal pain, which does not ease without increasing quantities of analgesics.
- Investigate any bowel injury thoroughly to determine viability at the site of injury. Whenever possible, repair all injuries intraoperatively.
- After intestinal perforation, the risk of sepsis is high. Look for early signs such as tachycardia, subnormal body temperature, depressed WBC count, and the appearance of immature white cell elements.
A thorough familiarity with pelvic anatomy is important to avoid injury at trocar entry, but it is even more critical in regard to operative injury. The small intestine spreads diffusely throughout the abdomen beneath the anterior abdominal wall. It lies beneath the umbilicus and anterior midline, whereas the large bowel is located at the periphery. The sigmoid colon swings left to right before joining the rectum anterior to the presacral space. The sigmoid junction with the descending colon lies well to the left of the midline, and the cecum lies at the pelvic brim to the right of midline.
In some women, the intestines droop into the pelvis and cover the adnexa, making adhesions between these structures highly likely following dissection in the vicinity of the tubes and ovaries.
Depending on the degree of redundancy of the mesentery of the cecum or sigmoid colon, these structures may droop into the pelvis and cover the adnexa. Therefore, adhesions are likely to develop between the large or small intestine, or both, and the adnexa following dissection in the vicinity of or immediately over the tubes and ovaries. Knowing the normal anatomic relationships is vital for restorative surgery.
When severe adhesions involve the large intestine, it is critical to know the anatomy of the retroperitoneum and be skilled enough to gain safe entry and to dissect that space to safely separate the adnexa when they are densely adhered to the pelvic sidewall in the area of the obturator fossa.
As laparoscopy evolves, the injury rate rises
Over the past 40 years, laparoscopy has evolved from an uncommonly utilized diagnostic tool to a minimally invasive alternative to laparotomy for even the most difficult and complex operations, reaching a high point with robotic laparoscopy. As this technology has developed, serious complications—to some degree, unique to laparoscopy—have increased. In the future, as less skilled surgeons perform a greater percentage of laparoscopic surgeries, a still greater number of complications will arise.
The frequency of intestinal perforation is not great relative to the total number of laparoscopic procedures performed. The TABLE lists several series totaling more than 380,000 laparoscopic operations. The risk of reported bowel perforation ranged from 0.6 to 6 for every 1,000 procedures, with a mean risk of 2.4 for every 1,000. However, these data are inconclusive because the total number of laparoscopic operations performed in the United States is not accurately known. Nor is the precise number of complications associated with these procedures known—specifically, the number of intestinal perforations—as no law requires them to be reported.
Research surveys are unreliable in many cases. In addition, the relative expertise of the surgeon is impossible to quantify. For example, although a surgeon may have many years of operative experience, it is unclear whether this always translates into skill or comfort with laparoscopic procedures. And, when a resident scrubs in with a faculty surgeon, any data collected fail to reflect which part of the surgery was performed by the resident and which by the fully trained gynecologist.
These unknown variables are important in terms of risk, surgical complications, and outcomes. Surgical skill is the greatest unknown factor in any outcome study of any surgical procedure.

Classifying intestinal injuries
As in the case of major vessel injury, intestinal injury sustained during laparoscopy can be classified as either:
- Injury secondary to the approach. This category refers to entry complications associated with creation of the pneumoperitoneum and insertion of primary and secondary trocars.
- Injury secondary to the procedure or operation. This type of injury occurs as a result of manipulation with various devices during laparoscopy. The devices may include probes, forceps, scissors, or energy devices such as laser, electrosurgical, and ultrasonic instruments.
How trocar injury happens
Several studies have demonstrated that abdominal adhesions place any patient into a high-risk category for trocar injury to the intestines. Patients who have undergone multiple laparotomies, like the patient in the case that opened this article, are more likely to have severe adhesions and fall into the highest risk category for bowel perforation.11 It is impossible to predict with any degree of accuracy whether the intestine is adherent to the entry site.
Pneumoperitoneum can be protective
Creation of a pneumoperitoneum creates a cushion of gas between the intestines and the anterior abdominal wall (provided the intestines are not adherent to the abdominal wall). Manufacturers of disposable trocars with a retractable shield recommend creating an adequate pneumoperitoneum so that the “safety shield” deploys quickly and properly, unlike direct insertion, in which no gas is infused and space is insufficient for complete shield activation.
Open laparoscopy techniques, which allow the surgeon to enter the peritoneal cavity by direct vision without a sharp trocar, may diminish but not eliminate the risk of bowel injury.
What the data show
Of the 130 intestinal injuries recently reported by Baggish, 62 of 81 (77%) small bowel injuries were related to trocar insertion, as were 20 of 49 (41%) large intestinal injuries.12 In other words, 82 of 130 intestinal injuries (63%) were the direct result of trocar entry.
Bhoyrul and associates reported 629 trocar injuries, of which 182 were visceral.13 Of the 32 deaths, six were secondary to unrecognized bowel injury. Of 176 nonfatal visceral injuries, 128 (73%) involved the intestines, and 22 were unrecognized.
Optical-access and open laparoscopic systems were designed to prevent such injuries. Sharp and colleagues reported 24 intestinal injuries out of a total of 79 complications (30%) associated with optical-access trocars after reviewing data obtained from the Medical Device Reports (MDR) and Maude databases maintained by the Food and Drug Administration.14 In the Baggish series, 4.6% of injuries were associated with open laparoscopy.12
Champault and colleagues reviewed complications in a survey of 103,852 operations.15 Although they recommended use of open laparoscopy as opposed to blind insertion, they presented no data on the safety of open techniques.
How intraoperative injury happens
Operative injury of the large or small bowel often occurs during sharp or blunt dissection, performed during laparoscopy using accessory mechanical or energy devices. The latter type of device is utilized increasingly because laparoscopic knot tying and suturing are rather awkward and slow, and laparoscopic suturing to control bleeding is difficult. The size of the needle required for laparoscopic suture placement must be small enough to navigate a trocar sleeve.
Avoid blunt dissection when adhesions are present
The separation of dense adhesions between the intestines and neighboring bowel, other viscera, or abdominal wall is risky when blunt dissection is used. The tensile strength of the fibrotic connective tissue may well exceed that of the thin intestinal wall. Tearing the adhesion free may bring with it a portion of the bowel wall. Such injuries are frequently missed or described as serosal injuries and left unexplored and unrepaired.
Hydrodissection is a safer alternative. It involves the infiltration of sterile water or saline under low pressure between the parietal peritoneum and underlying retroperitoneal structures, providing a safe and natural plane for dissection. In addition, when the CO2 laser is used, the liquid acts as a heat sink to absorb any penetrating laser energy.
Energy devices create thermal effects
Energy devices used to cut tissue during operative laparoscopy coagulate blood vessels in a variety of ways, but the common pathway is thermal. Many hypotheses have evolved to explain how vessels are sealed, but none has demonstrated nonthermal activity except for cryocoagulation.
The devices most commonly used for cutting and hemostasis at laparoscopy are:
- electrosurgical (both monopolar and bipolar). Bipolar electrosurgical devices have advantages over monopolar devices when it comes to high-frequency leaks, direct coupling, and capacitive coupling.
- laser (CO2, holmium:YAG, Nd:YAG, KTP-532, argon). As I mentioned, CO2 laser devices are effectively backstopped by water, especially in strategic areas such as over and around intestines, major vessels, and the ureters.
- ultrasonic (Harmonic Scalpel, ultrasonic aspirator [CUSA]).
Laser and ultrasonic devices do not require a flow of electrons to create coagulation, but do produce heat that will spread peripherally by thermal conduction from the zone of impact (target).
The extent of energy-inflicted injury cannot be predicted
Inadvertent injury with energy devices can occur directly through contact with the bowel, indirectly by heat conduction through tissue, through capacitive coupling (monopolar electrical only), and by forward scatter (laser only).
Upon direct contact with the intestine, energy devices cut into the tissue in a manner similar to mechanical scissors or a knife but produce a larger wound. The reason? The transfer of heat to areas adjacent to the primary wound produces additional necrosis. Heat conduction, capacitive coupling, high-frequency leaks, and front scatter coagulate the intestinal wall with subsequent tissue devitalization and necrosis, the extent of which depends on the power density at contact and the duration of energy applied.
It is impossible to predict the depth or area of devitalization in energy-inflicted injury by visualization of the event.
In the Baggish review of 130 intestinal injuries, the number of injuries sustained during the operative procedure was 19 involving the small intestine and 29 involving the large bowel.12 Of this subset, 44% (21 cases) were secondary to the use of energy devices, with monopolar electrosurgical instruments alone accounting for 9 (43%) of the injuries.
Even best-laid plans can go awry
Despite our best intentions and precautions, accidents do sometimes happen, and bowel injury is no exception.In Part 2 of this article, I detail steps you can take to detect injuries in as timely a manner as possible.

CASE Postoperative abdominal pain. Is it gastroenteritis?
R.B., 35 years old, undergoes laparoscopic adhesiolysis for abdominal pain. Previously, she underwent exploratory laparotomy for a ruptured tubal pregnancy and, in separate operations, right oophorectomy via laparotomy for a ruptured corpus luteum cyst and diagnostic laparoscopy.
During the current surgery, extensive adhesions are observed, including interloop intestinal adhesions. The adhesions are lysed using monopolar scissors and a needle electrode, and R.B. is discharged home the same day.
Later that day and the next day, R.B. complains of abdominal pain that does not respond to prescribed analgesics, as well as nausea and vomiting. A nurse practitioner takes her call and prescribes a stronger analgesic, an antiemetic, and an antibiotic.
The following day, the patient’s husband telephones the treating gynecologist to report that his wife is still experiencing severe pain and nausea. He is told to bring her to the office, where she is described as having mild lower abdominal tenderness and mild rebound. An abdominal radiograph shows air-fluid levels and distended bowel. The gynecologist determines that the patient is experiencing gastroenteritis.
On postop day 3, R.B. continues to suffer from severe abdominal pain, nausea, and vomiting, and is unable to get out of bed. Her husband takes her to the emergency room at another hospital, where she is found to have diffuse peritonitis, absent bowel sounds, and:
- temperature, 101.8°F
- heart rate, 130/min
- respiratory rate, 24/min
- blood pressure, 90/60 mm Hg
- white blood cell (WBC) count, 21.5 × 103/μL
- x-ray showing free air.
A general surgeon performs an exploratory laparotomy and finds foul-smelling abdominal fluid, 200 to 300 mL of pus, and a 1-cm perforation of the sigmoid colon. He performs sigmoid colon resection and a left-colon colostomy. A second laparotomy is necessary to drain a subphrenic abscess.
Four months later, the colostomy is taken down and bowel continuity is established.
Subsequently, the patient experiences episodes of gaseous and fecal incontinence, which are thought to be secondary to nerve damage. A ventral hernia is also diagnosed.
Could this outcome have been avoided?
No physician would wish a major complication of surgery upon any patient. Yet, sometimes, preventive efforts fall short of the goal or the physician is slow to suspect injury when the patient experiences postoperative abdominal pain and other symptoms. Intestinal injury may not be common during laparoscopy, but it is certainly not rare. And the longer diagnosis is delayed, the greater the risk of sepsis, even death.
Recognizing the limitations of laparoscopic surgery is a first step toward reducing the complication rate.1,2 The ability to determine when laparotomy would better serve the patient’s interests is also critical, and prompt diagnosis and repair of any complication that does occur will ensure and speed the patient’s recovery.
The most serious complications associated with diagnostic and operative laparoscopy are major vessel and intestinal injuries. Both types of injury significantly raise the risk of mortality, which ranges from 2% to 23%.3,4 The overall risk of injury to the gastrointestinal tract averages 1.6 to 2.0 for every 1,000 cases. The risk of major vessel injury averages 0.5 for every 1,000 cases.5-9
In an earlier article for OBG Management, I reviewed vascular injury during laparoscopy.10 In Part 1 of this article, I focus on ways to avoid intestinal injury.In Part 2 , I outline strategies to identify it in a timely manner when it does occur.
- Avoid laparoscopy when severe adhesions are anticipated—such as when the patient has a history of multiple laparotomies, or when significant adhesions have been documented.
- Be aware that laparoscopy carries additional risks beyond those of the primary surgical procedure, owing to factors peculiar to endoscopic technique and instrumentation.
- Consider open laparoscopy or insert the primary trocar at an alternative location, such as the left upper quadrant, when the patient has a history of laparotomy.
- Avoid blunt dissection for anything other than mild (filmy) adhesions. Sharp dissection associated with hydrodissection is the safest method of adhesiolysis. Clear visualization of the operative site is the sine qua non for precise dissection.
- Avoid monopolar electrosurgical devices for laparoscopic surgery whenever possible. Also remember that bipolar and ultrasonic devices can cause thermal injury by heat conduction as well as by direct application. Laser energy will continue beyond the target unless provision is made to absorb the residual energy.
- At the conclusion of any laparoscopic procedure, especially after adhesiolysis or bowel dissection, inspect the intestines and include the details in the operative report.
- After any laparoscopic procedure, if the patient does not improve steadily, the first presumptive diagnosis to be excluded is injury secondary to the procedure or technique.
- The major symptom of intestinal perforation is abdominal pain, which does not ease without increasing quantities of analgesics.
- Investigate any bowel injury thoroughly to determine viability at the site of injury. Whenever possible, repair all injuries intraoperatively.
- After intestinal perforation, the risk of sepsis is high. Look for early signs such as tachycardia, subnormal body temperature, depressed WBC count, and the appearance of immature white cell elements.
A thorough familiarity with pelvic anatomy is important to avoid injury at trocar entry, but it is even more critical in regard to operative injury. The small intestine spreads diffusely throughout the abdomen beneath the anterior abdominal wall. It lies beneath the umbilicus and anterior midline, whereas the large bowel is located at the periphery. The sigmoid colon swings left to right before joining the rectum anterior to the presacral space. The sigmoid junction with the descending colon lies well to the left of the midline, and the cecum lies at the pelvic brim to the right of midline.
In some women, the intestines droop into the pelvis and cover the adnexa, making adhesions between these structures highly likely following dissection in the vicinity of the tubes and ovaries.
Depending on the degree of redundancy of the mesentery of the cecum or sigmoid colon, these structures may droop into the pelvis and cover the adnexa. Therefore, adhesions are likely to develop between the large or small intestine, or both, and the adnexa following dissection in the vicinity of or immediately over the tubes and ovaries. Knowing the normal anatomic relationships is vital for restorative surgery.
When severe adhesions involve the large intestine, it is critical to know the anatomy of the retroperitoneum and be skilled enough to gain safe entry and to dissect that space to safely separate the adnexa when they are densely adhered to the pelvic sidewall in the area of the obturator fossa.
As laparoscopy evolves, the injury rate rises
Over the past 40 years, laparoscopy has evolved from an uncommonly utilized diagnostic tool to a minimally invasive alternative to laparotomy for even the most difficult and complex operations, reaching a high point with robotic laparoscopy. As this technology has developed, serious complications—to some degree, unique to laparoscopy—have increased. In the future, as less skilled surgeons perform a greater percentage of laparoscopic surgeries, a still greater number of complications will arise.
The frequency of intestinal perforation is not great relative to the total number of laparoscopic procedures performed. The TABLE lists several series totaling more than 380,000 laparoscopic operations. The risk of reported bowel perforation ranged from 0.6 to 6 for every 1,000 procedures, with a mean risk of 2.4 for every 1,000. However, these data are inconclusive because the total number of laparoscopic operations performed in the United States is not accurately known. Nor is the precise number of complications associated with these procedures known—specifically, the number of intestinal perforations—as no law requires them to be reported.
Research surveys are unreliable in many cases. In addition, the relative expertise of the surgeon is impossible to quantify. For example, although a surgeon may have many years of operative experience, it is unclear whether this always translates into skill or comfort with laparoscopic procedures. And, when a resident scrubs in with a faculty surgeon, any data collected fail to reflect which part of the surgery was performed by the resident and which by the fully trained gynecologist.
These unknown variables are important in terms of risk, surgical complications, and outcomes. Surgical skill is the greatest unknown factor in any outcome study of any surgical procedure.

In an earlier article for OBG Management, I reviewed vascular injury during laparoscopy.10 In Part 1 of this article, I focus on ways to avoid intestinal injury.In Part 2 , I outline strategies to identify it in a timely manner when it does occur.
- Avoid laparoscopy when severe adhesions are anticipated—such as when the patient has a history of multiple laparotomies, or when significant adhesions have been documented.
- Be aware that laparoscopy carries additional risks beyond those of the primary surgical procedure, owing to factors peculiar to endoscopic technique and instrumentation.
- Consider open laparoscopy or insert the primary trocar at an alternative location, such as the left upper quadrant, when the patient has a history of laparotomy.
- Avoid blunt dissection for anything other than mild (filmy) adhesions. Sharp dissection associated with hydrodissection is the safest method of adhesiolysis. Clear visualization of the operative site is the sine qua non for precise dissection.
- Avoid monopolar electrosurgical devices for laparoscopic surgery whenever possible. Also remember that bipolar and ultrasonic devices can cause thermal injury by heat conduction as well as by direct application. Laser energy will continue beyond the target unless provision is made to absorb the residual energy.
- At the conclusion of any laparoscopic procedure, especially after adhesiolysis or bowel dissection, inspect the intestines and include the details in the operative report.
- After any laparoscopic procedure, if the patient does not improve steadily, the first presumptive diagnosis to be excluded is injury secondary to the procedure or technique.
- The major symptom of intestinal perforation is abdominal pain, which does not ease without increasing quantities of analgesics.
- Investigate any bowel injury thoroughly to determine viability at the site of injury. Whenever possible, repair all injuries intraoperatively.
- After intestinal perforation, the risk of sepsis is high. Look for early signs such as tachycardia, subnormal body temperature, depressed WBC count, and the appearance of immature white cell elements.
A thorough familiarity with pelvic anatomy is important to avoid injury at trocar entry, but it is even more critical in regard to operative injury. The small intestine spreads diffusely throughout the abdomen beneath the anterior abdominal wall. It lies beneath the umbilicus and anterior midline, whereas the large bowel is located at the periphery. The sigmoid colon swings left to right before joining the rectum anterior to the presacral space. The sigmoid junction with the descending colon lies well to the left of the midline, and the cecum lies at the pelvic brim to the right of midline.
In some women, the intestines droop into the pelvis and cover the adnexa, making adhesions between these structures highly likely following dissection in the vicinity of the tubes and ovaries.
Depending on the degree of redundancy of the mesentery of the cecum or sigmoid colon, these structures may droop into the pelvis and cover the adnexa. Therefore, adhesions are likely to develop between the large or small intestine, or both, and the adnexa following dissection in the vicinity of or immediately over the tubes and ovaries. Knowing the normal anatomic relationships is vital for restorative surgery.
When severe adhesions involve the large intestine, it is critical to know the anatomy of the retroperitoneum and be skilled enough to gain safe entry and to dissect that space to safely separate the adnexa when they are densely adhered to the pelvic sidewall in the area of the obturator fossa.
As laparoscopy evolves, the injury rate rises
Over the past 40 years, laparoscopy has evolved from an uncommonly utilized diagnostic tool to a minimally invasive alternative to laparotomy for even the most difficult and complex operations, reaching a high point with robotic laparoscopy. As this technology has developed, serious complications—to some degree, unique to laparoscopy—have increased. In the future, as less skilled surgeons perform a greater percentage of laparoscopic surgeries, a still greater number of complications will arise.
The frequency of intestinal perforation is not great relative to the total number of laparoscopic procedures performed. The TABLE lists several series totaling more than 380,000 laparoscopic operations. The risk of reported bowel perforation ranged from 0.6 to 6 for every 1,000 procedures, with a mean risk of 2.4 for every 1,000. However, these data are inconclusive because the total number of laparoscopic operations performed in the United States is not accurately known. Nor is the precise number of complications associated with these procedures known—specifically, the number of intestinal perforations—as no law requires them to be reported.
Research surveys are unreliable in many cases. In addition, the relative expertise of the surgeon is impossible to quantify. For example, although a surgeon may have many years of operative experience, it is unclear whether this always translates into skill or comfort with laparoscopic procedures. And, when a resident scrubs in with a faculty surgeon, any data collected fail to reflect which part of the surgery was performed by the resident and which by the fully trained gynecologist.
These unknown variables are important in terms of risk, surgical complications, and outcomes. Surgical skill is the greatest unknown factor in any outcome study of any surgical procedure.

Classifying intestinal injuries
As in the case of major vessel injury, intestinal injury sustained during laparoscopy can be classified as either:
- Injury secondary to the approach. This category refers to entry complications associated with creation of the pneumoperitoneum and insertion of primary and secondary trocars.
- Injury secondary to the procedure or operation. This type of injury occurs as a result of manipulation with various devices during laparoscopy. The devices may include probes, forceps, scissors, or energy devices such as laser, electrosurgical, and ultrasonic instruments.
How trocar injury happens
Several studies have demonstrated that abdominal adhesions place any patient into a high-risk category for trocar injury to the intestines. Patients who have undergone multiple laparotomies, like the patient in the case that opened this article, are more likely to have severe adhesions and fall into the highest risk category for bowel perforation.11 It is impossible to predict with any degree of accuracy whether the intestine is adherent to the entry site.
Pneumoperitoneum can be protective
Creation of a pneumoperitoneum creates a cushion of gas between the intestines and the anterior abdominal wall (provided the intestines are not adherent to the abdominal wall). Manufacturers of disposable trocars with a retractable shield recommend creating an adequate pneumoperitoneum so that the “safety shield” deploys quickly and properly, unlike direct insertion, in which no gas is infused and space is insufficient for complete shield activation.
Open laparoscopy techniques, which allow the surgeon to enter the peritoneal cavity by direct vision without a sharp trocar, may diminish but not eliminate the risk of bowel injury.
What the data show
Of the 130 intestinal injuries recently reported by Baggish, 62 of 81 (77%) small bowel injuries were related to trocar insertion, as were 20 of 49 (41%) large intestinal injuries.12 In other words, 82 of 130 intestinal injuries (63%) were the direct result of trocar entry.
Bhoyrul and associates reported 629 trocar injuries, of which 182 were visceral.13 Of the 32 deaths, six were secondary to unrecognized bowel injury. Of 176 nonfatal visceral injuries, 128 (73%) involved the intestines, and 22 were unrecognized.
Optical-access and open laparoscopic systems were designed to prevent such injuries. Sharp and colleagues reported 24 intestinal injuries out of a total of 79 complications (30%) associated with optical-access trocars after reviewing data obtained from the Medical Device Reports (MDR) and Maude databases maintained by the Food and Drug Administration.14 In the Baggish series, 4.6% of injuries were associated with open laparoscopy.12
Champault and colleagues reviewed complications in a survey of 103,852 operations.15 Although they recommended use of open laparoscopy as opposed to blind insertion, they presented no data on the safety of open techniques.
How intraoperative injury happens
Operative injury of the large or small bowel often occurs during sharp or blunt dissection, performed during laparoscopy using accessory mechanical or energy devices. The latter type of device is utilized increasingly because laparoscopic knot tying and suturing are rather awkward and slow, and laparoscopic suturing to control bleeding is difficult. The size of the needle required for laparoscopic suture placement must be small enough to navigate a trocar sleeve.
Avoid blunt dissection when adhesions are present
The separation of dense adhesions between the intestines and neighboring bowel, other viscera, or abdominal wall is risky when blunt dissection is used. The tensile strength of the fibrotic connective tissue may well exceed that of the thin intestinal wall. Tearing the adhesion free may bring with it a portion of the bowel wall. Such injuries are frequently missed or described as serosal injuries and left unexplored and unrepaired.
Hydrodissection is a safer alternative. It involves the infiltration of sterile water or saline under low pressure between the parietal peritoneum and underlying retroperitoneal structures, providing a safe and natural plane for dissection. In addition, when the CO2 laser is used, the liquid acts as a heat sink to absorb any penetrating laser energy.
Energy devices create thermal effects
Energy devices used to cut tissue during operative laparoscopy coagulate blood vessels in a variety of ways, but the common pathway is thermal. Many hypotheses have evolved to explain how vessels are sealed, but none has demonstrated nonthermal activity except for cryocoagulation.
The devices most commonly used for cutting and hemostasis at laparoscopy are:
- electrosurgical (both monopolar and bipolar). Bipolar electrosurgical devices have advantages over monopolar devices when it comes to high-frequency leaks, direct coupling, and capacitive coupling.
- laser (CO2, holmium:YAG, Nd:YAG, KTP-532, argon). As I mentioned, CO2 laser devices are effectively backstopped by water, especially in strategic areas such as over and around intestines, major vessels, and the ureters.
- ultrasonic (Harmonic Scalpel, ultrasonic aspirator [CUSA]).
Laser and ultrasonic devices do not require a flow of electrons to create coagulation, but do produce heat that will spread peripherally by thermal conduction from the zone of impact (target).
The extent of energy-inflicted injury cannot be predicted
Inadvertent injury with energy devices can occur directly through contact with the bowel, indirectly by heat conduction through tissue, through capacitive coupling (monopolar electrical only), and by forward scatter (laser only).
Upon direct contact with the intestine, energy devices cut into the tissue in a manner similar to mechanical scissors or a knife but produce a larger wound. The reason? The transfer of heat to areas adjacent to the primary wound produces additional necrosis. Heat conduction, capacitive coupling, high-frequency leaks, and front scatter coagulate the intestinal wall with subsequent tissue devitalization and necrosis, the extent of which depends on the power density at contact and the duration of energy applied.
It is impossible to predict the depth or area of devitalization in energy-inflicted injury by visualization of the event.
In the Baggish review of 130 intestinal injuries, the number of injuries sustained during the operative procedure was 19 involving the small intestine and 29 involving the large bowel.12 Of this subset, 44% (21 cases) were secondary to the use of energy devices, with monopolar electrosurgical instruments alone accounting for 9 (43%) of the injuries.
Even best-laid plans can go awry
Despite our best intentions and precautions, accidents do sometimes happen, and bowel injury is no exception.In Part 2 of this article, I detail steps you can take to detect injuries in as timely a manner as possible.
