Bacterial vaginosis (BV) is one of the most common conditions associated with vaginal discharge among women of reproductive age. It is characterized by a polymicrobial alteration of the vaginal microbiome, and most distinctly, a relative absence of vaginal lactobacilli. This review discusses the microbiology, epidemiology, specific obstetric and gynecologic complications, clinical manifestations, diagnosis, and treatment of BV.

The role of vaginal flora

Estrogen has a fundamental role in regulating the normal state of the vagina. In a woman’s reproductive years, estrogen increases glycogen in the vaginal epithelial cells, and the increased glycogen concentration promotes colonization by lactobacilli. The lack of estrogen in pre- and postmenopausal women inhibits the growth of the vaginal lactobacilli, leading to a high vaginal pH, which facilitates the growth of bacteria, particularly anaerobes, that can cause BV.

The vaginal microbiome is polymicrobial and has been classified into at least 5 community state types (CSTs). Four CSTs are dominated by lactobacilli. A fifth CST is characterized by the absence of lactobacilli and high concentrations of obligate or facultative anaerobes.¹ The hydrogen peroxide–producing lactobacilli predominate in normal vaginal flora and make up 70% to 90% of the total microbiome. These hydrogen peroxide–producing lactobacilli are associated with reduced vaginal proinflammatory cytokines and a highly acidic vaginal pH. Both factors defend against sexually transmitted infections (STIs).²

BV is a polymicrobial disorder marked by the significant reduction in the number of vaginal lactobacilli (FIGURE 1). A recent study showed that BV is associated first with a decrease in Lactobacillus crispatus, followed by increase in Prevotella bivia, Gardnerella vaginalis, Atopobium vaginae, and Megasphaera type 1.³ The polymicrobial load is increased by a factor of up to 1,000, compared with normal vaginal flora.⁴ BV should be considered a biofilm infection caused by adherence of G vaginalis to the vaginal epithelium.⁵ This biofilm creates a favorable environment for the overgrowth of obligate anaerobic bacteria.

BMI factors into epidemiology

BV is the leading cause of vaginal discharge in reproductive-age women. In the United States, the National Health and Nutrition Examination Survey estimated a prevalence of 29% in the general population and 50% in Black women aged 14 to 49 years.⁶ In 2013, Kenyon and colleagues performed a systematic review to assess the worldwide epidemiology of BV, and the prevalence varied by country. Within the US population, rates were highest among non-Hispanic, Black women.⁷ Brookheart and colleagues demonstrated that, even after controlling for race, overweight and obese women had a higher frequency of BV compared with leaner women. In this investigation, the overall prevalence of BV was 28.1%. When categorized by body mass index (BMI), the prevalence was 21.3% in lean women, 30.4% in overweight women, and 34.5% in obese women (P<.001). The authors also found that Black women had a higher prevalence, independent of BMI, compared with White women.⁸

Complications may occur. BV is notable for having several serious sequelae in both pregnant and nonpregnant women. For obstetric patients, these sequelae include an increased risk of preterm birth; first trimester spontaneous abortion, particularly in the setting of in vitro fertilization; intra-amniotic infection; and endometritis.^9,10 The risk of preterm birth increases by a factor of 2 in infected women; however, most women with BV do not deliver preterm.⁴ The risk of endometritis is increased 6-fold in women with BV.¹¹ Nonpregnant women with BV are at increased risk for pelvic inflammatory disease, postoperative infections, and an increased susceptibility to STIs such as chlamydia, gonorrhea, herpes simplex virus, and HIV.^12-15 The risk for vaginal-cuff cellulitis and abscess after hysterectomy is increased 6-fold in the setting of BV.¹⁶

Clinical manifestations

BV is characterized by a milky, homogenous, and malodorous vaginal discharge accompanied by vulvovaginal discomfort and vulvar irritation. Vaginal inflammation typically is absent. The associated odor is fishy, and this odor is accentuated when potassium hydroxide (KOH) is added to the vaginal discharge (amine or “whiff” test) or after the patient has coitus. The distinctive odor is due to the release of organic acids and polyamines that are byproducts of anaerobic bacterial metabolism of putrescine and cadaverine. This release is enhanced by exposure of vaginal secretions to alkaline substances such as KOH or semen.

Diagnostic tests and criteria. The diagnosis of BV is made using Amsel criteria or Gram stain with Nugent scoring; bacterial culture is not recommended. Amsel criteria include:

• homogenous, thin, white-gray discharge
• >20% clue cells on saline microscopy (FIGURE 2)
• a pH >4.5 of vaginal fluid
• positive KOH whiff test.

For diagnosis, 3 of the 4 Amsel criteria must be present.¹⁷ Gram stain with Nugent score typically is used for research purposes. Nugent scoring assigns a value to different bacterial morphotypes on Gram stain of vaginal secretions. A score of 7 to 10 is consistent with BV.¹⁸

Oral and topical treatments

Treatment is recommended for symptomatic patients. Treatment may reduce the risk of transmission and acquisition of other STIs. The TABLE summarizes Centers for Disease Control and Prevention (CDC) guidelines for BV treatment,¹⁹ with options including both oral and topical regimens. Oral and topical metronidazole and oral and topical clindamycin are equally effective at eradicating the local source of infection²⁰; however, only oral metronidazole and oral clindamycin are effective in preventing the systemic complications of BV. Oral metronidazole has more adverse effects than oral clindamycin—including nausea, vomiting, diarrhea, and a disulfiram-like reaction (characterized by flushing, dizziness, throbbing headache, chest and abdominal discomfort, and a distinct hangover effect in addition to nausea and vomiting). However, oral clindamycin can cause antibiotic-associated colitis and is more expensive than metronidazole.

Currently, there are no single-dose regimens for the treatment of BV readily available in the United States. Secnidazole, a 5-nitroimidazole with a longer half-life than metronidazole, (17 vs 8 hours) has been used as therapy in Europe and Asia but is not yet available commercially in the United States.²¹ Hiller and colleagues found that 1 g and 2 g secnidazole oral granules were superior to placebo in treating BV.²² A larger randomized trial comparing this regimen to standard treatment is necessary before this therapy is adopted as the standard of care.

Continue to: Managing recurrent disease...

Managing recurrent disease, a common problem. Bradshaw and colleagues noted that, although the initial treatment of BV is effective in approximately 80% of women, up to 50% have a recurrence within 12 months.²³ Data are limited regarding optimal treatment for recurrent infections; however, most regimens consist of some form of suppressive therapy. One regimen includes one full applicator of metronidazole vaginal gel 0.75% twice weekly for 6 months.²⁴ A second regimen consists of vaginal boric acid capsules 600 mg once daily at bedtime for 21 days. Upon completion of boric acid therapy, metronidazole vaginal gel 0.75% should be administered twice weekly for 6 months.²⁵ A third option is oral metronidazole 2 g and fluconazole 250 mg once every month.²⁶ Of note, boric acid can be fatal if consumed orally and is not recommended during pregnancy.

Most recently, a randomized trial evaluated the ability of L crispatus to prevent BV recurrence. After completion of standard treatment therapy with metronidazole, women were randomly assigned to receive vaginally administered L crispatus (152 patients) or placebo (76 patients) for 11 weeks. In the intention-to-treat population, recurrent BV occurred in 30% of patients in the L crispatus group and 45% of patients in the placebo group. The use of L crispatus significantly reduced recurrence of BV by one-third (P = .01; 95% confidence interval [CI], 0.44–0.87).²⁷ These findings are encouraging; however, confirmatory studies are needed before adopting this as standard of care.

Should sexual partners be treated as well? BV has not traditionally been considered an STI, and the CDC does not currently recommend treatment of partners of women who have BV. However, in women who have sex with women, the rate of BV concordance is high, and in women who have sex with men, coitus can clearly influence disease activity. Therefore, in patients with refractory BV, we recommend treatment of the sexual partner(s) with metronidazole 500 mg orally twice daily for 7 days. For women having sex with men, we also recommend consistent use of condoms, at least until the patient’s infection is better controlled.²⁸

CASE Resolved

The patient’s clinical findings are indicative of BV. This condition is associated with an increased risk of preterm delivery and intrapartum and postpartum infection. To reduce the risk of these systemic complications, she was treated with oral metronidazole 500 mg twice daily for 7 days. Within 1 week of completing treatment, she noted complete resolution of the malodorous discharge. ●

Although recent events have spurred much discourse regarding systemic racism, the issue of racism is old, very old. Unfortunately, our gynecologic surgery history is rooted in racism, with numerous documented procedures performed on enslaved women without their consent. Over the years, racism has continued to permeate gynecologic surgery in so far as access to quality care, patient outcomes, and inclusion in research. While racial disparities with regard to stage at diagnosis and survival of gynecologic malignancy has been documented, this discussion is outside the scope of this article.

Racial disparities in gyn surgery: The evidence

More data exist with regard to hysterectomy and racism than with any other gynecologic surgery. Most notably, a minimally invasive approach to hysterectomy is less likely to occur for minority women, even in universally insured patient populations and when controlling for factors predisposing patients to an abdominal approach.

Minority women undergo MIS for hysterectomy less often

Ranjit and colleagues assessed hysterectomy data between 2006 and 2010 from National TRICARE Prime and Prime Plus data to evaluate if racial differences existed in a universally insured population of US Armed Services members and their dependents. African American patients were significantly less likely than White patients to undergo a total vaginal hysterectomy (relative risk ratio [RRR], 0.63; 95% confidence interval [CI], 0.58–0.69) or total laparoscopic hysterectomy (RRR, 0.65; 95% CI, 0.60–0.71) compared with abdominal hysterectomy. Asian patients were also less likely to receive the vaginal (RRR, 0.71; 95% CI, 0.60–0.84) or laparoscopic (RRR, 0.69; 95% CI, 0.58–0.83) approach to hysterectomy than White patients.¹ These findings remained when controlled for surgery indication, suggesting that racial inequity was not attributed solely to preoperative patient factors. However, the authors could not control for specific patient factors such as body mass index and uterine weight.

Katon and colleagues reviewed data on patients who underwent hysterectomy for uterine fibroids at a Veterans Affairs hospital and found 99 excess abdominal hysterectomies were performed among Black women compared with White women. Despite controlling for predisposing factors related to abdominal surgery, facility, and geography (teaching hospital, higher volume hysterectomy), Black women were still less likely to undergo minimally invasive hysterectomy.² The difference in approach between both groups remained largely unexplained.²

Pollack and colleagues reviewed hysterectomy data from Agency for Healthcare Research and Quality Healthcare Cost and Utilization Project State Inpatient Database and State Ambulatory Surgery Databases between 2010 and 2014 from Colorado, Florida, Maryland, New Jersey, and New York. They found that African American and Hispanic women were less likely to undergo vaginal (adjusted standardized prevalence ratio [aPR], 0.93; 95% CI, 0.90–0.96 and aPR, 0.95; 95% CI, 0.93−0.97, respectively) and laparoscopic hysterectomy (aPR, 0.90; 95% CI, 0.87−0.94 and aPR, 0.95; 95% CI, 0.92−0.98, respectively) than White women. Asian/Pacific Islander women were less likely to undergo vaginal hysterectomy (aPR, 0.88; 95% CI, 0.81−0.96). They also found that hospitals providing care to more racial/ethnic minority women performed more abdominal and fewer vaginal procedures compared with other hospitals.³

Sanei-Moghaddam and colleagues reviewed data from University of Pittsburgh Medical Center–affiliated hospitals and found that European-American women had 0.47 times lower odds of undergoing abdominal hysterectomy compared with ethnic/race minority group women. Also, traditional Medicaid and Medicare enrollees had 2- to 4-times higher odds of having an abdominal hysterectomy compared with patients with commercial insurance.⁴ Evidently, insurance and payer status and hospital, along with race, were associated with abdominal hysterectomy.

Postop complications higher among Black women. One study of the National Surgical Quality Improvement Program 2015 hysterectomy database found that Black women were more likely to undergo open hysterectomy than White women despite controlling for patient factors associated with open hysterectomy, including uterine weight (adjusted odds ratio [aOR], 2.02; 95% CI, 1.85–2.20).⁵ Black women also were more likely to develop both minor and major postoperative complications despite controlling for route of hysterectomy (major complications aOR, 1.56; 95% CI, 1.25–1.95 and minor complications aOR, 1.27; 95% CI, 1.11–1.47). Their study was limited by inability to control for surgeon volume and experience and hospital-specific factors.⁵

Hospital size and surgeon volume found to play a role in disparities. In an effort to address hospital and surgeon factors and racial disparities in minimally invasive hysterectomy, Mehta and colleagues evaluated an all payer system in Maryland. Black (reference White; aOR, 0.70; 95% CI, 0.63–0.78) and Hispanic patients (aOR, 0.62; 95% CI, 0.48–0.80) were less likely to undergo minimally invasive hysterectomy. Patients who had surgery at small- and medium-sized hospitals or by medium-volume surgeons (medium vs high volume: OR, 0.78; 95% CI, 0.71–0.87) were also more likely to undergo open hysterectomy.⁶ The study authors suggest increased utilization of higher volume surgeons for referrals or to assist lower-volume surgeons as potential solutions to address racial disparities.⁶

Continue to: Surgical outcome disparities extend beyond hysterectomy route...

While the bulk of data with regard to gynecologic surgery and racism addresses minimally invasive approach to treatment of fibroids and hysterectomy, limited data regarding ectopic pregnancy and adnexal surgery reveal similar findings. Hsu and colleagues reported that Black (adjusted risk ratio [aRR], 0.76; 95% CI, 0.69–0.85) and Hispanic (aRR, 0.80; 95% CI, 0.66–0.96) women treated surgically for ectopic pregnancy were less likely to undergo tubal-sparing procedures than White women.⁷ Their study did not control for human chorionic gonadotropin levels, ectopic size, or comorbidities as measured by the Elixhauser Comorbidity Index.

The data regarding gynecologic surgery and racial inequity are sparse but manifest differences that are unexplained entirely by patient payer status and individual patient factors. Studies do confirm hospital and surgeon characteristics play a part in provision of minimally invasive hysterectomy.

Forming a conceptual re-framework to achieve health equity

The centuries-long impact of racism on our field, and more specifically on gynecologic surgery, will take time and a conscious effort to overcome. In 2001, the Institute of Medicine outlined 6 domains for improvement, amongst them equitable care—“ensuring quality of care does not vary because of characteristics.”⁸ As highlighted above, some aspects of gynecologic surgery have proven to be inequitable, specifically in the provision of minimally invasive hysterectomy and treatment of ectopic pregnancy in Black women. The lack of studies on racism and gynecologic surgery as it pertains to other benign gynecologic conditions highlights the need for more research and measures that target each level of racism and, ultimately, achieve health equity.

Priority #1: Support and funding. In 2016, the Institute for Healthcare Improvement (IHI) published a white paper describing a framework to bring about health equity. First and foremost, institutions and individuals must prioritize health equity by obtaining leadership support and adequate funding.⁹ In August 2020, several leading obstetrics and gynecology organizations published a joint statement highlighting their initial plan of action to address racism and provide equitable care.¹⁰ As leading professional organizations prioritize equity, we can hope institutions and departments continue to do so as well.

Priority #2: Measuring the extent of the problem. Once adequate support and funding is established, the IHI recommends⁹:

• establishing structures and processes with an overseeing committee and dedicated budget
• deploying strategies with comprehensive data collection and pertinent metrics.

Continue to: Applying the levels of racism to a new framework...

Given the numerous untouched areas of research and components contributing to racial disparities in gynecologic surgery, determining a starting point can prove overwhelming. We suggest employing a conceptual framework that considers the different levels of racism (TABLE 1).

Three different levels of racism have been described previously:

• systemic/institutionalized,
• personally mediated
• internalized.^11,12

Systemic racism refers to differential access to services and goods in society and power within society, for example housing, education, medical care, and voting and representation.¹² Systemic racism is arguably the overarching form of racism. The studies by Mehta and colleagues and Pollack et al specifically highlight a lack of adequate access to minimally invasive hysterectomy and a subsequent increase in complication rates in minority race groups.^3,13 Access to care is only one example of systemic racism that requires action at multiple levels by professional organizations, hospitals, community organizations, and individual departments with multiple targeted solutions (TABLE 2).

Mediated racism. The second form of racism is personally mediated racism, in other words discrimination and prejudice formed by preconceived notions of a person based on their race.¹² In the joint statement published by the leading obstetrics and gynecology organizations in August 2020, a recognition of race as a social construct without the biological weight we have long afforded it was made explicit. This realization can be applied in the day-to-day categorization of patients and, most notably, the formation of a diagnosis and treatment plan.

A concrete example of potentially biased treatment is illustrated when limiting management options to the “unreliable” patient. Exposure to stereotypes and misinformation can develop into implicit bias and subsequently make the most intelligent, compassionate provider show behavior with microaggressions. This subtle behavior can play a major role in patient-provider communication and in turn affect care satisfaction, provider trust, and shared decision making.¹⁴ The Implicit bias Association Test or MPathic-VR virtual human simulations can be used to identify provider-specific implicit bias.^14,15

Internalized racism. Lastly, internalized racism refers to the individual’s acceptance of negative messages regarding their own abilities and worth,¹² which is seen commonly in imposter syndrome. Imposter syndrome, which is a failure to internalize one’s own successes and persistent fear of being discovered as a fraud, a condition which has been more commonly seen in ethnic minority groups.¹⁶ A patient’s internalized racism can manifest as self-devaluation and helplessness which may make a patient less likely to question their treatment.^12,17 Moreover, some evidence exists indicating that patients with diabetes identified physician discrimination and internalized racism as factors impeding shared decision making.¹⁸

The next steps first require recognition

Racial inequity has long infiltrated our medical field and the discussion surrounding the effects of racism on our patients and providers, and research, is long overdue. Although research continues to emerge regarding race inequity and gynecologic surgery, much remains to be done. In recognizing the levels of racism and the roles they play in our provision of good, equitable, patient-centered care, we—as individuals, departments, and organizations—can combat racism and strive for health equity. ●

Although recent events have spurred much discourse regarding systemic racism, the issue of racism is old, very old. Unfortunately, our gynecologic surgery history is rooted in racism, with numerous documented procedures performed on enslaved women without their consent. Over the years, racism has continued to permeate gynecologic surgery in so far as access to quality care, patient outcomes, and inclusion in research. While racial disparities with regard to stage at diagnosis and survival of gynecologic malignancy has been documented, this discussion is outside the scope of this article.

Racial disparities in gyn surgery: The evidence

More data exist with regard to hysterectomy and racism than with any other gynecologic surgery. Most notably, a minimally invasive approach to hysterectomy is less likely to occur for minority women, even in universally insured patient populations and when controlling for factors predisposing patients to an abdominal approach.

Minority women undergo MIS for hysterectomy less often

Ranjit and colleagues assessed hysterectomy data between 2006 and 2010 from National TRICARE Prime and Prime Plus data to evaluate if racial differences existed in a universally insured population of US Armed Services members and their dependents. African American patients were significantly less likely than White patients to undergo a total vaginal hysterectomy (relative risk ratio [RRR], 0.63; 95% confidence interval [CI], 0.58–0.69) or total laparoscopic hysterectomy (RRR, 0.65; 95% CI, 0.60–0.71) compared with abdominal hysterectomy. Asian patients were also less likely to receive the vaginal (RRR, 0.71; 95% CI, 0.60–0.84) or laparoscopic (RRR, 0.69; 95% CI, 0.58–0.83) approach to hysterectomy than White patients.¹ These findings remained when controlled for surgery indication, suggesting that racial inequity was not attributed solely to preoperative patient factors. However, the authors could not control for specific patient factors such as body mass index and uterine weight.

Katon and colleagues reviewed data on patients who underwent hysterectomy for uterine fibroids at a Veterans Affairs hospital and found 99 excess abdominal hysterectomies were performed among Black women compared with White women. Despite controlling for predisposing factors related to abdominal surgery, facility, and geography (teaching hospital, higher volume hysterectomy), Black women were still less likely to undergo minimally invasive hysterectomy.² The difference in approach between both groups remained largely unexplained.²

Pollack and colleagues reviewed hysterectomy data from Agency for Healthcare Research and Quality Healthcare Cost and Utilization Project State Inpatient Database and State Ambulatory Surgery Databases between 2010 and 2014 from Colorado, Florida, Maryland, New Jersey, and New York. They found that African American and Hispanic women were less likely to undergo vaginal (adjusted standardized prevalence ratio [aPR], 0.93; 95% CI, 0.90–0.96 and aPR, 0.95; 95% CI, 0.93−0.97, respectively) and laparoscopic hysterectomy (aPR, 0.90; 95% CI, 0.87−0.94 and aPR, 0.95; 95% CI, 0.92−0.98, respectively) than White women. Asian/Pacific Islander women were less likely to undergo vaginal hysterectomy (aPR, 0.88; 95% CI, 0.81−0.96). They also found that hospitals providing care to more racial/ethnic minority women performed more abdominal and fewer vaginal procedures compared with other hospitals.³

Sanei-Moghaddam and colleagues reviewed data from University of Pittsburgh Medical Center–affiliated hospitals and found that European-American women had 0.47 times lower odds of undergoing abdominal hysterectomy compared with ethnic/race minority group women. Also, traditional Medicaid and Medicare enrollees had 2- to 4-times higher odds of having an abdominal hysterectomy compared with patients with commercial insurance.⁴ Evidently, insurance and payer status and hospital, along with race, were associated with abdominal hysterectomy.

Postop complications higher among Black women. One study of the National Surgical Quality Improvement Program 2015 hysterectomy database found that Black women were more likely to undergo open hysterectomy than White women despite controlling for patient factors associated with open hysterectomy, including uterine weight (adjusted odds ratio [aOR], 2.02; 95% CI, 1.85–2.20).⁵ Black women also were more likely to develop both minor and major postoperative complications despite controlling for route of hysterectomy (major complications aOR, 1.56; 95% CI, 1.25–1.95 and minor complications aOR, 1.27; 95% CI, 1.11–1.47). Their study was limited by inability to control for surgeon volume and experience and hospital-specific factors.⁵

Hospital size and surgeon volume found to play a role in disparities. In an effort to address hospital and surgeon factors and racial disparities in minimally invasive hysterectomy, Mehta and colleagues evaluated an all payer system in Maryland. Black (reference White; aOR, 0.70; 95% CI, 0.63–0.78) and Hispanic patients (aOR, 0.62; 95% CI, 0.48–0.80) were less likely to undergo minimally invasive hysterectomy. Patients who had surgery at small- and medium-sized hospitals or by medium-volume surgeons (medium vs high volume: OR, 0.78; 95% CI, 0.71–0.87) were also more likely to undergo open hysterectomy.⁶ The study authors suggest increased utilization of higher volume surgeons for referrals or to assist lower-volume surgeons as potential solutions to address racial disparities.⁶

“Mini-sponge” device shows potential to treat PPH

During a pilot study, reports Obstetrx, 9 patients, treated at the University Teaching Hospital in Lusaka, Zambia, did not respond to conventional PPH management options after vaginal birth but did respond, with bleeding resolved in 60 seconds and no adverse events, to the XSTAT device. The device was left in place for a mean time of 1 hour, and none of the patients required further surgical procedures or blood transfusions. The initial placement time of XSTAT (mean time to placement, 62 seconds) was faster than times reported for balloon uterine tamponade devices. The pilot study results were published in Obstetrics & Gynecology.

XSTAT is US Food and Drug Administration–approved to treat high-flow arterial bleeding in prehospital trauma settings, and Obstetrx is planning to submit for 510k clearance in 2022, after the conclusion of a follow-up PPH trial in 2021.

A woman’s fertility window is typically the 5 days leading up to ovulation, with peak fertility in the 2 to 3 days before ovulation. There are other options for measuring that fertile window, including luteinizing hormone (LH) tests; however, Prima-Temp reports that Priya predicts the fertile window an average of 2.6 days before tests for LH. Utilizing continuous core body temperature measurement, Priya detects subtle changes in temperature patterns that occur prior to ovulation. The app portion of the technology stores and analyzes the temperature measurements, for a high-tech fertility alert system that also offers clinical diagnostic support.

Since the first baby was born after a uterus transplantation in Sweden in 2014, uterus transplantation has been rapidly transitioning toward clinical reality.¹ Several teams in the United States and multiple teams worldwide have performed the procedure, with the total number of worldwide surgeries performed nearing 100.

Uterus transplantation is the first and only true treatment for women with absolute uterine factor infertility – estimated to affect 1 in 500 women – and is filling an unmet need for this population of women. Women who have sought participation in uterus transplantation research have had complex and meaningful reasons and motivations for doing so.² Combined with an accumulation of successful pregnancies, this makes continued research and technical improvement a worthy endeavor.

Most of the births thus far have occurred through the living-donor model; the initial Swedish trial involved nine women, seven of whom completed the procedure with viable transplants from living donors, and gave birth to eight healthy children. (Two required hysterectomy prior to attempted embryo transfer.³)

The Cleveland Clinic opted to build its first – and still ongoing – trial focusing on deceased-donor uterus transplants on the premise that such an approach obviates any risk to the donor and presents the fewest ethical challenges at the current time. Of eight uterus transplants performed thus far at the Cleveland Clinic, there have been three live births and two graft failures. As of early 2021, there was one ongoing pregnancy and two patients in preparation for embryo transfer.

Thus far, neither the living- nor deceased-donor model of uterus transplantation has been demonstrated to be superior. However, as data accrues from deceased donor studies, we will be able to more directly compare outcomes.

In the meantime, alongside a rapid ascent of clinical landmarks – the first live birth in the United States from living-donor uterus transplantation in 2017 at Baylor University Medical Center in Houston,⁴ for instance, and the first live birth in the United States from deceased-donor uterus transplantation in 2019 at the Cleveland Clinic ^– there have been significant improvements in surgical retrieval of the uterus and in the optimization of graft performance.⁵

Most notably, the utero-ovarian vein has been used successfully in living donors to achieve venous drainage of the graft. This has lessened the risks of deep pelvic dissection in the living donor and made the transition to laparoscopic and robotic approaches in the living donor much easier.
 

Donor procurement, venous drainage

Adequate circulatory inflow and outflow for the transplanted uterus are essential both for the prevention of ischemia and thrombosis, which have been major causes of graft failure, and for meeting the increased demands of blood flow during pregnancy. Of the two, the outflow is the more challenging component.

Venous drainage traditionally has been accomplished through the use of the uterine veins, which drain into the internal iliac veins; often the vascular graft will include a portion of the internal iliac vessel which can be connected via anastomoses to the external iliac vein classically in deceased donors. Typically, the gynecologic surgeon on the team performs the vaginal anastomosis and suspension of the uterus, while the transplant surgeons perform the venous and arterial anastomoses.

In the living-donor model, procurement and dissection of these often unpredictable and tortuous complexes in the deep pelvis – particularly the branching uterine veins that lie in close proximity to the ureter, bladder, other blood vessels, and rectum – can be risky. The anatomic variants in the uterine vein are numerous, and even in one patient, a comprehensive dissection on one side cannot be expected to be mirrored on the contralateral side.

In addition to the risk of injury to the donor, the anastomosis may be unsuccessful as the veins are thinly walled and challenging to suture. As such, multiple modifications have been developed, often adapted to the donor’s anatomy and the caliber and accessibility of vessels. Preoperative vascular imaging with CT and/or MRI may help to identify suitable candidates and also may facilitate presurgical planning of which vessels may be selected for use.

Recently, surgeons performing living-donor transplantations have successfully used the more accessible and less risky ovarian and/or utero-ovarian veins for venous anastomosis. In 2019, for instance, a team in Pune, India, reported laparoscopically dissecting the donor ovarian veins and a portion of the internal iliac artery, and completing anastomosis with bilateral donor internal iliac arteries to recipient internal iliac arteries, and bilateral donor ovarian veins to recipient external iliac veins.⁶ It is significant that these smaller-caliber vessels were found to able to support the uterus through pregnancy.

We must be cautious, however, to avoid removing donors’ ovaries. Oophorectomy for women in their 40s can result in significant long-term medical sequelae. Surgeons at Baylor have achieved at least one live birth after harvesting the donor’s utero-ovarian veins while conserving the ovaries – a significant advancement for the living-donor model.⁴

There is tremendous interest in developing minimally invasive approaches to further reduce living-donor risk. The Swedish team has completed a series of eight robotic hysterectomies in living-donor uterus transplantations as part of a second trial. Addressing the reality of a learning curve, their study was designed around a step-wise approach, mastering initial steps first – e.g., dissections of the uterovaginal fossa, arteries, and ureters – and ultimately converting to laparotomy.⁷ In the United States, Baylor University has now completed at least five completely robotic living-donor hysterectomies with complete vaginal extraction.

Published data on robotic surgery suggests that surgical access and perioperative visualization of the vessels may be improved. And as minimally invasive approaches are adopted and improved, the length of donor surgery – 10-13 hours of operating room time in the original Swedish series – should diminish, as should the morbidity associated with laparotomy.

Surgical acquisition of a uterine graft from a deceased donor diminishes concerns for injury to nearby structures. Therefore, although it is a technically similar procedure, a deceased-donor model allows more flexibility with the length, caliber, and number of vessels that can be used for anastomosis. The internal iliac vessels and even portions of the external iliac vessels and ovarian vessels can be used to allow maximum flexibility.⁸

Surgical technique for uterus recipients

For the recipient surgery, entry is achieved via a midline, vertical laparotomy. The external iliac vessels are exposed, and the sites of vascular anastomoses are identified. The peritoneal reflection of the bladder is identified and dissected away to expose the anterior vagina, and the vagina is opened to a diameter that matches the donor, typically using a monopolar electrosurgical cutting instrument.

Courtesy Cleveland Clinic

The vault of the donor vagina will be attached to the recipient’s existing vagina or vaginal pouch. It is important to identify recipient vaginal mucosa and incorporate it into the vaginal anastomosis to reduce the risk of vaginal stricture. We recommend that the vaginal mucosa be tagged with PDS II sutures or grasped with allis clamps to prevent retraction.

Surgical teams have taken multiple approaches to vaginal anastomosis. The Cleveland Clinic has used both a running suture as well as a horizontal mattress stitch for closure. For the latter, a 30-inch double-armed 2.0 Vicryl allows for complete suturing of the recipient vagina – with eight stitches placed circumferentially – before the uterus is placed. Both ends of the suture are passed intra-abdominal to intravaginal in the recipient.⁹

Once the donor uterus is suspended, attention focuses on vascular anastomosis, with bilateral end-to-side anastomosis between the donor anterior division of the internal iliac arteries and the external iliac vessels of the recipient, and with venous drainage commonly achieved through the uterine veins draining into the internal or external iliac vein of the recipient. As mentioned, recent cases involving living donors have also demonstrated success with the use of ovarian and/or utero-ovarian veins. Care should be taken to avoid having tension or twisting across the anastomosis.

Courtesy Cleveland Clinic

After adequate graft perfusion is confirmed, with the uterus turning from a dusky color to a pink and well-perfused organ, the vaginal anastomosis is completed, with the arms of the double-armed suture passed through the donor vagina, from intravaginal to intra-abdominal. Tension should be evenly spread along the recipient and donor vagina in order to reduce the formation of granulation tissue and the severity of future vaginal stricturing.

For uterine fixation, polypropylene sutures are placed between the graft uterosacral ligaments and recipient uterine rudiments, and between the graft round ligaments and the recipient pelvic side wall at the level of the deep inguinal ring.

Current uterus transplantation protocols require removal of the uterus after one or two live births are achieved, so that recipients will not be exposed to long-term immunosuppression.
 

Complications and controversies

Postoperative vaginal strictures can make embryo transfer difficult and are a common complication in both living- and deceased-donor models. The Cleveland Clinic team has applied techniques from vaginal reconstructive surgery to try to reduce the occurrence of postoperative strictures – mainly increasing attention paid to anastomosis tissue–site preparation and closure of the anastomosis using a tension-free interrupted suture technique, as described above.⁹ The jury is out on whether such changes are sufficient, and a more complete understanding of the causes of vaginal stricture is needed.

Other perioperative complications include infection and graft thrombosis, both of which typically result in urgent graft hysterectomy. During pregnancy, one of our patients experienced abnormal placentation, though this was not thought to be related to uterus transplantation.⁵

The U.S. Uterus Transplant Consortium (USUTC) is a group of active programs that are sharing ideas and outcomes and advocating for continued research in this rapidly developing field. Uterine transplants require collaboration with transplant surgery, transplant medicine, infectious disease, gynecologic surgery, high-risk obstetrics, and other specialties. While significant progress has been made in a short period of time, uterine transplantation is still in its early stages, and transplants should be done in institutions that have the capacity for mentorship, bioethical oversight, and long-term follow-up of donors, recipients, and offspring.

The USUTC has recently proposed guidelines for nomenclature related to operative technique, vascular anatomy, and uterine transplantation outcomes.¹⁰ It proposes standardizing the names for the four veins originating from the uterus (to eliminate current inconsistency), which will be important as optimal strategies for vascular anastomoses are discussed and determined.

In addition, the consortium is creating a registry for the rigorous collection of data on procedures and outcomes (from menstruation and pregnancy through delivery, graft removal, and long-term follow-up). A registry has also been proposed by the International Society for Uterine Transplantation.

A major question remains in our field: Is the living-donor or deceased-donor uterus transplant the best approach? Knowledge of the quality of the uterus is greater preoperatively within a living-donor model, but no matter how minimally invasive the technique, the donor still assumes some risk of prolonged surgery and extensive pelvic dissection for a transplant that is not lifesaving.

On the other hand, deceased-donor transplants require additional layers of organization and coordination, and the availability of suitable deceased-donor uteri will likely not be sufficient to meet the current demand. Many of us in the field believe that the future of uterine transplantation will involve some combination of living- and deceased-donor transplants – similar to other solid organ transplant programs.

Since the first baby was born after a uterus transplantation in Sweden in 2014, uterus transplantation has been rapidly transitioning toward clinical reality.¹ Several teams in the United States and multiple teams worldwide have performed the procedure, with the total number of worldwide surgeries performed nearing 100.

Uterus transplantation is the first and only true treatment for women with absolute uterine factor infertility – estimated to affect 1 in 500 women – and is filling an unmet need for this population of women. Women who have sought participation in uterus transplantation research have had complex and meaningful reasons and motivations for doing so.² Combined with an accumulation of successful pregnancies, this makes continued research and technical improvement a worthy endeavor.

Most of the births thus far have occurred through the living-donor model; the initial Swedish trial involved nine women, seven of whom completed the procedure with viable transplants from living donors, and gave birth to eight healthy children. (Two required hysterectomy prior to attempted embryo transfer.³)

Until the advent of uterus transplantation, there was no restorative procedure available to a woman presenting with an absent uterus or nonfunctioning uterus; that is, absolute uterine factor infertility (AUFI). It is estimated that 1 in 500 women of childbearing age are affected by AUFI.^1,2 An absent uterus may be secondary to uterine agenesis or Mayer-Rokitansky-Küster-Hauser syndrome (MRKH), which occurs in 1 in 4,500 women.^3,4 (Because women with MRKH have a normal karyotype, their children can be normal, without urogenital malformations.⁵)

Given the fact that roughly 240,000 hysterectomies are performed in the United States each year for women aged under 44 years, hysterectomy is the most common cause of acquired AUFI.⁶AUFI may also be secondary to a uterus that will not support a viable pregnancy; that is, a nonfunctional uterus. In this case, medical or surgical treatment is impossible to enable normal physiological uterine function to produce a successful pregnancy. Causal factors include Müllerian anomalies, severe intrauterine adhesions/Asherman syndrome, uterine fibroids not amendable to surgical therapy, and radiation injury not responsive to medical therapy.

Prior to uterus transplantation, parenthood could only be achieved via adoption, foster parenting, or gestational carrier. While utilizing a gestational carrier is legal in most U.S. states, most countries of western Europe as well as Brazil and Japan, to name a few, do not allow the use of gestational carriers. For some women, moreover, the desire is not only to have a baby, but to carry a child as well.

For this edition of the Master Class in Gynecologic Surgery, I have enlisted the assistance of Rebecca Flyckt, MD, division chief of reproductive endocrinology and infertility at University Hospitals Cleveland Medical Center and associate professor at Case Western Reserve University, Cleveland, and Elliott G. Richards, MD, director of reproductive endocrinology and infertility research at the Cleveland Clinic, to discuss the current and future state of uterus transplantation.

Dr. Flyckt and Dr. Richards have both contributed to the uterus transplantation team at the Cleveland Clinic and are founding members of the U.S. Uterus Transplant Consortium. They are well published in the field of minimally invasive gynecology and reproductive endocrinology and infertility. It is truly a pleasure to welcome them both to this edition of the Master Class in Gynecologic Surgery.

In Part 1 of this article in the December 2020 issue of OBG Management, I discussed the reasons that pessaries are an effective treatment option for many women with pelvic organ prolapse (POP) and stress urinary incontinence (SUI) and provided details on the types of pessaries available.

In this article, I highlight the steps in fitting a pessary, pessary aftercare, and potential complications associated with pessary use. In addition, I discuss the effectiveness of pessary treatment for POP and SUI as well as for preterm labor prevention and defecatory disorders.

The pessary fitting process

For a given patient, the best size pessary is the smallest one that will not fall out. The only “rule” for fitting a pessary is that a woman’s internal vaginal caliber should be wider than her introitus.

When fitting a pessary, goals include that the selected pessary:

• should be comfortable for the patient to wear
• is not easily expelled
• does not interfere with urination or defecation
• does not cause vaginal irritation.

The presence or absence of a cervix or uterus does not affect pessary choice.

Most experts agree that the process for fitting the right size pessary is one of trial and error. As with fitting a contraceptive diaphragm, the clinician should perform a manual examination to estimate the integrity and width of the perineum and the depth of the vagina to roughly approximate the pessary size that might best fit. Using a set of “fitting pessaries,” a pessary of the estimated size should be placed into the vagina and the fit evaluated as to whether the device is too big, too small, or appropriate. If the pessary is easily expelled, larger sizes should be tried until the pessary remains in place or the patient is uncomfortable. Once the pessary is in place, the clinician should be able to run his or her finger around the entire pessary; if this is not possible, the pessary is too tight. In addition, the pessary should remain more than one finger breadth above the introitus when the patient is standing or bearing down.

Since many patients who require a pessary are elderly, their perineal skin and vaginal mucosa may be atrophic and fragile. Inserting a pessary can be uncomfortable and can cause abrasions or tears. Successfully fitting a pessary may require extra care under these circumstances. The following steps may help alleviate these difficulties:

• Explain the fitting process to the patient in detail.
• Employ lubrication liberally.
• Enlarge the introitus by applying gentle digital pressure on the posterior fourchette.
• Apply 2% lidocaine ointment several minutes prior to pessary fitting to help decrease patient discomfort.
• Treat the patient for several weeks with vaginal estrogen cream before attempting to fit a pessary if severe vulvovaginal atrophy is present.

Once the type and size of the pessary are selected and a pessary is inserted, evaluate the patient with the pessary in place. Assess for the following:

Discomfort. Ask the patient if she feels discomfort with the pessary in position. A patient with a properly fitting pessary should not feel that it is in place. If she does feel discomfort initially, the discomfort will only increase with time and the issue should be addressed at that time.

Expulsion. Test to make certain that the pessary is not easily expelled from the vagina. Have the patient walk, cough, squat, and even jump if possible.

Urination. Have the patient urinate with the pessary in place. This tests for her ability to void while wearing the pessary and shows whether the contraction of pelvic muscles during voiding results in expulsion of the pessary. (Experience shows that it is best to do this with a plastic “hat” over the toilet so that if the pessary is expelled, it does not drop into the bowl.)

Re-examination. After these provocative tests, examine the patient again to ensure that the pessary has not slid out of place.

Depending on whether or not your office stocks pessaries, at this point the patient is either given the correct type and size of pessary or it is ordered for her. If the former, the patient should try placing it herself; if she is unable to, the clinician should place it for her. In either event, its position should be checked. If the pessary has to be ordered, the patient must schedule an appointment to return for pessary insertion.

Whether the pessary is supplied by the office or ordered, instruct the patient on how to insert and remove the pessary, how frequently to remove it for cleansing (see below), and signs to watch for, such as vaginal bleeding, inability to void or defecate, or pelvic pain.

It is advisable to schedule a subsequent visit for 2 to 3 weeks after initial pessary placement to assess how the patient is doing and to address any issues that have developed.

Continue to: Special circumstances...

It is safe for a patient with a pessary in place to undergo magnetic resonance imaging.¹ Patients should be informed, however, that full body scans, such as at airports, will detect pessaries. Patients may need to obtain a physician’s note to document that the pessary is a medical device.

Finally, several factors may prevent successful pessary fitting. These include prior pelvic surgery, obesity, short vaginal length (less than 6–7 cm), and a vaginal introitus width of greater than 4 finger breadths.

Necessary pessary aftercare

Once a pessary is in place and the patient is comfortable with it, the only maintenance necessary is the pessary’s intermittent removal for cleansing and for evaluation of the vaginal mucosa for erosion and ulcerations. How frequently this should be done varies based on the type of pessary, the amount of discharge that a woman produces, whether or not an odor develops after prolonged wearing of the pessary, and whether or not the patient’s vaginal mucosa has been abraded.

The question of timing for pessary cleaning

Although there are many opinions about how often pessaries should be removed and cleaned, no data in the literature support any specific interval. Pessaries that are easily removed by women themselves can be cleaned as frequently as desired, often on a weekly basis. The patient simply removes the pessary, washes it with soap and water, and reinserts it. For pessaries that are difficult to remove (such as the Gellhorn, cube, or donut) or for women who are physically unable to remove their own ring pessary, the clinician should remove and clean the pessary in the office every 3 to 6 months. It has been shown that there is no difference in complications from pessary use with either of these intervals.²

Prior to any vaginal surgical procedure, patients must be instructed to remove their pessary 10 to 14 days beforehand so that the surgeon can see the full extent of prolapse when making decisions about reconstruction and so that any vaginal mucosal erosions or abrasions have time to heal.

Office visits for follow-up care

The pessary “cleaning visit” has several goals, including to:

• see if the pessary is meeting the patient’s needs in terms of resolving symptoms of prolapse and/or restoring urinary continence
• discuss with the patient any problems she may be having, such as pelvic discomfort or pressure, difficulty voiding or defecating, excessive vaginal discharge, or vaginal odor
• check for vaginal mucosal erosion or ulceration; such vaginal lesions often can be prevented by the prophylactic use of either estrogen vaginal cream twice weekly or the continuous use of an estradiol vaginal ring in addition to the pessary
• evaluate the condition of the pessary itself and clean it with soap and water.

Continue to: Potential complications of pessary use...

The most common complications experienced by pessary users are:

Odor or excessive discharge. Bacterial vaginosis (BV) occurs more frequently in women who use pessaries. The symptoms of BV can be minimized—but unfortunately not totally eliminated—by the prophylactic use of antiseptic vaginal creams or gels, such as metronidazole, clindamycin, Trimo-San (oxyquinoline sulfate and sodium lauryl sulfate), and others. Inserting the gel vaginally once a week can significantly reduce discharge and odor.³

Vaginal mucosal erosion and ulceration. These are treated by removing the pessary for 2 weeks during which time estrogen cream is applied daily or an estradiol vaginal ring is put in place. If no resolution occurs after 2 weeks, the nonhealing vaginal mucosa should be biopsied.

Pressure on the rectum or bladder. If the pessary causes significant discomfort or interferes with voiding function, then either a different size or a different type pessary should be tried

Patients may discontinue pessary use for a variety of reasons. Among these are:

• discomfort
• inadequate improvement of POP or incontinence symptoms
• expulsion of the pessary during daily activities
• the patient’s desire for surgery instead
• worsening of urine leakage
• difficulty inserting or removing the pessary
• damage to the vaginal mucosa
• pain during removal of the pessary in the office.

Pessary effectiveness for POP and SUI symptoms

As might be expected with a device that is available in so many forms and is used to treat varied types of POP and SUI, the data concerning the success rates of pessary use vary considerably. These rates depend on the definition of success, that is, complete or partial control of prolapse and/or incontinence; which devices are being evaluated; and the nature and severity of the POP and/or SUI being treated.

That being said, a review of the literature reveals that the rates of prolapse symptom relief vary from 48% to 92% (TABLE 1).^4-13

As for success in relieving symptoms of incontinence, studies show improvements in from 40% to 77% of patients (TABLE 2).^6,8,14-17

In addition, some studies show a 50% improvement in bowel symptoms (urgency, obstruction, and anal incontinence) with the use of a pessary.^9,18

How pessaries compare with surgery

While surgery has the advantage of being a one-time fix with a very high rate of initial success in correcting both POP and incontinence, surgery also has potential drawbacks:

• It is an invasive procedure with the discomfort and risk of complications any surgery entails.
• There is a relatively high rate of prolapse recurrence.
• It exposes the patient to the possibility of mesh erosion if mesh is employed either for POP support or incontinence treatment.

Pessaries, on the other hand, are inexpensive, nonsurgical, removable, and allow for immediate correction of symptoms. Moreover, if the pessary is tried and is found to be unsatisfactory, surgery always can be performed subsequently.

Drawbacks of pessary treatment compared with surgery include the:

• ongoing need to wear an artificial internal device
• need for intermittent pessary removal and cleansing
• inability to have sexual intercourse with certain kinds of pessaries in place
• possible accumulation of vaginal discharge and odor.

Sexual activity and pessaries

Studies by Fernando, Meriwether, and Kuhn concur that for a substantial number of pessary users who are sexually active, both frequency and satisfaction with sexual intercourse are increased.^8,19,20 Kuhn further showed that desire, orgasm, and lubrication improved with the use of pessaries.²⁰ While some types of pessaries do require removal for intercourse, Clemons reported that issues involving sexual activity are not associated with pessary discontinuation.²¹

Using a pessary to predict a surgical outcome

Because a pessary elevates the pelvic organs, supports the vaginal walls, and lifts the bladder and urethra into a position that simulates the results of surgical repair, trial placement of a pessary can be used as a fairly accurate predictive tool to model what pelvic support and continence status will be after a proposed surgical procedure.^22,23 This is especially important because a significant number of patients with POP will have their occult stress incontinence unmasked following a reparative procedure.²⁴ A brief pessary trial prior to surgery, therefore, can be a useful tool for both patient and surgeon.

Continue to: Pessaries for prevention of preterm labor...

Pessaries for prevention of preterm labor

Almost 1 in 10 births in the United States occurs before 37 completed weeks of gestation.²⁵ Obstetricians have long thought that in women at risk for preterm delivery, the use of a pessary might help reduce the pressure of the growing uterus on the cervix and thus help prevent premature cervical dilation. It also has been thought that use of a pessary would be a safer and less invasive alternative to cervical cerclage. Many studies have evaluated the use of pessaries for the prevention of preterm labor with a mixture of positive (TABLE 3)^26-29 and negative results (TABLE 4).^30-33

From these data, it is reasonable to conclude that:

• The final answer concerning the effectiveness or lack thereof of pessary use in preventing preterm delivery is not yet in.
• Any advantage there might be to using pessaries to prevent preterm delivery cannot be too significant if multiple studies show as many negative outcomes as positive ones.

Pessary effectiveness in defecatory disorders

Vaginal birth has the potential to create multiple anatomic injuries in the anus, lower pelvis, and perineum that can affect defecation and bowel control. Tears of the anal sphincter, whether obvious or occult, may heal incompletely or be repaired inadequately.³⁴ Nerve innervation of the perianal and perineal areas can be interrupted or damaged by stretching, tearing, or prolonged compression. Of healthy parous adult women, 7% to 16% admit incontinence of gas or feces.^35,36

In addition, when a rectocele is present, stool in the lower rectum may cause bulging of the anterior rectal wall into the vagina, preventing stool from passing out of the anus. This sometimes requires women to digitally press their posterior vaginal walls during defecation to evacuate stool successfully. The question thus arises as to whether or not pessary placement and subsequent relief of rectoceles might facilitate bowel movements and decrease or eliminate defecatory dysfunction.

As with the issue of pessary use for prevention of preterm delivery, the answer is mixed. For instance, while Brazell¹⁸ showed that there was an overall improvement in bowel symptoms in pessary users, a study by Komesu¹⁰ did not demonstrate improvement.

There is, however, a relatively new device specifically designed to control defecatory problems: the vaginal bowel control system (Eclipse; Pelvalon). The silicon device is placed intravaginally as one does a pessary. After insertion, it is inflated via a valve and syringe. It works by putting pressure on and reversibly closing the lower rectum, thus blocking the uncontrolled passage of stool and gas. It can be worn continuously or intermittently, but it does need to be deflated for normal bowel movements. One trial of this device demonstrated a 50% reduction in incontinence episodes with a patient satisfaction rate of 84% at 3 months.³⁷ This device may well prove to be a valuable nonsurgical approach to the treatment of fecal incontinence. Unfortunately, the device is relatively expensive and usually is not covered by insurance as third-party payers do not consider it to be a pessary (which generally is covered).

Practice management particulars

Useful information on Current Procedural Terminology codes for pessaries, diagnostic codes, and the cost of various pessaries is provided in TABLE 5,³⁸TABLE 6,³⁹ and TABLE 7.^40-42

A contemporary device used since antiquity

Pessaries, considered “old-fashioned” by many gynecologists, are actually a very cost-effective and useful tool for the correction of POP and SUI. It behooves all who provide medical care to women to be familiar with them, to know when they might be useful, and to know how to fit and prescribe them. ●

In Part 1 of this article in the December 2020 issue of OBG Management, I discussed the reasons that pessaries are an effective treatment option for many women with pelvic organ prolapse (POP) and stress urinary incontinence (SUI) and provided details on the types of pessaries available.

In addition, some studies show a 50% improvement in bowel symptoms (urgency, obstruction, and anal incontinence) with the use of a pessary.^9,18

How pessaries compare with surgery

While surgery has the advantage of being a one-time fix with a very high rate of initial success in correcting both POP and incontinence, surgery also has potential drawbacks:

• It is an invasive procedure with the discomfort and risk of complications any surgery entails.
• There is a relatively high rate of prolapse recurrence.
• It exposes the patient to the possibility of mesh erosion if mesh is employed either for POP support or incontinence treatment.

Pessaries, on the other hand, are inexpensive, nonsurgical, removable, and allow for immediate correction of symptoms. Moreover, if the pessary is tried and is found to be unsatisfactory, surgery always can be performed subsequently.

Drawbacks of pessary treatment compared with surgery include the:

• ongoing need to wear an artificial internal device
• need for intermittent pessary removal and cleansing
• inability to have sexual intercourse with certain kinds of pessaries in place
• possible accumulation of vaginal discharge and odor.

Sexual activity and pessaries

Studies by Fernando, Meriwether, and Kuhn concur that for a substantial number of pessary users who are sexually active, both frequency and satisfaction with sexual intercourse are increased.^8,19,20 Kuhn further showed that desire, orgasm, and lubrication improved with the use of pessaries.²⁰ While some types of pessaries do require removal for intercourse, Clemons reported that issues involving sexual activity are not associated with pessary discontinuation.²¹

Using a pessary to predict a surgical outcome

Because a pessary elevates the pelvic organs, supports the vaginal walls, and lifts the bladder and urethra into a position that simulates the results of surgical repair, trial placement of a pessary can be used as a fairly accurate predictive tool to model what pelvic support and continence status will be after a proposed surgical procedure.^22,23 This is especially important because a significant number of patients with POP will have their occult stress incontinence unmasked following a reparative procedure.²⁴ A brief pessary trial prior to surgery, therefore, can be a useful tool for both patient and surgeon.

Pessaries for prevention of preterm labor

Almost 1 in 10 births in the United States occurs before 37 completed weeks of gestation.²⁵ Obstetricians have long thought that in women at risk for preterm delivery, the use of a pessary might help reduce the pressure of the growing uterus on the cervix and thus help prevent premature cervical dilation. It also has been thought that use of a pessary would be a safer and less invasive alternative to cervical cerclage. Many studies have evaluated the use of pessaries for the prevention of preterm labor with a mixture of positive (TABLE 3)^26-29 and negative results (TABLE 4).^30-33

From these data, it is reasonable to conclude that:

• The final answer concerning the effectiveness or lack thereof of pessary use in preventing preterm delivery is not yet in.
• Any advantage there might be to using pessaries to prevent preterm delivery cannot be too significant if multiple studies show as many negative outcomes as positive ones.

Pessary effectiveness in defecatory disorders

Vaginal birth has the potential to create multiple anatomic injuries in the anus, lower pelvis, and perineum that can affect defecation and bowel control. Tears of the anal sphincter, whether obvious or occult, may heal incompletely or be repaired inadequately.³⁴ Nerve innervation of the perianal and perineal areas can be interrupted or damaged by stretching, tearing, or prolonged compression. Of healthy parous adult women, 7% to 16% admit incontinence of gas or feces.^35,36

In addition, when a rectocele is present, stool in the lower rectum may cause bulging of the anterior rectal wall into the vagina, preventing stool from passing out of the anus. This sometimes requires women to digitally press their posterior vaginal walls during defecation to evacuate stool successfully. The question thus arises as to whether or not pessary placement and subsequent relief of rectoceles might facilitate bowel movements and decrease or eliminate defecatory dysfunction.

As with the issue of pessary use for prevention of preterm delivery, the answer is mixed. For instance, while Brazell¹⁸ showed that there was an overall improvement in bowel symptoms in pessary users, a study by Komesu¹⁰ did not demonstrate improvement.

There is, however, a relatively new device specifically designed to control defecatory problems: the vaginal bowel control system (Eclipse; Pelvalon). The silicon device is placed intravaginally as one does a pessary. After insertion, it is inflated via a valve and syringe. It works by putting pressure on and reversibly closing the lower rectum, thus blocking the uncontrolled passage of stool and gas. It can be worn continuously or intermittently, but it does need to be deflated for normal bowel movements. One trial of this device demonstrated a 50% reduction in incontinence episodes with a patient satisfaction rate of 84% at 3 months.³⁷ This device may well prove to be a valuable nonsurgical approach to the treatment of fecal incontinence. Unfortunately, the device is relatively expensive and usually is not covered by insurance as third-party payers do not consider it to be a pessary (which generally is covered).

Practice management particulars

A contemporary device used since antiquity

Pessaries, considered “old-fashioned” by many gynecologists, are actually a very cost-effective and useful tool for the correction of POP and SUI. It behooves all who provide medical care to women to be familiar with them, to know when they might be useful, and to know how to fit and prescribe them. ●

In Part 1 of this article in the December 2020 issue of OBG Management, I discussed the reasons that pessaries are an effective treatment option for many women with pelvic organ prolapse (POP) and stress urinary incontinence (SUI) and provided details on the types of pessaries available.

In this article, I highlight the steps in fitting a pessary, pessary aftercare, and potential complications associated with pessary use. In addition, I discuss the effectiveness of pessary treatment for POP and SUI as well as for preterm labor prevention and defecatory disorders.

The pessary fitting process

For a given patient, the best size pessary is the smallest one that will not fall out. The only “rule” for fitting a pessary is that a woman’s internal vaginal caliber should be wider than her introitus.

When fitting a pessary, goals include that the selected pessary:

• should be comfortable for the patient to wear
• is not easily expelled
• does not interfere with urination or defecation
• does not cause vaginal irritation.

The presence or absence of a cervix or uterus does not affect pessary choice.

Most experts agree that the process for fitting the right size pessary is one of trial and error. As with fitting a contraceptive diaphragm, the clinician should perform a manual examination to estimate the integrity and width of the perineum and the depth of the vagina to roughly approximate the pessary size that might best fit. Using a set of “fitting pessaries,” a pessary of the estimated size should be placed into the vagina and the fit evaluated as to whether the device is too big, too small, or appropriate. If the pessary is easily expelled, larger sizes should be tried until the pessary remains in place or the patient is uncomfortable. Once the pessary is in place, the clinician should be able to run his or her finger around the entire pessary; if this is not possible, the pessary is too tight. In addition, the pessary should remain more than one finger breadth above the introitus when the patient is standing or bearing down.

Since many patients who require a pessary are elderly, their perineal skin and vaginal mucosa may be atrophic and fragile. Inserting a pessary can be uncomfortable and can cause abrasions or tears. Successfully fitting a pessary may require extra care under these circumstances. The following steps may help alleviate these difficulties:

• Explain the fitting process to the patient in detail.
• Employ lubrication liberally.
• Enlarge the introitus by applying gentle digital pressure on the posterior fourchette.
• Apply 2% lidocaine ointment several minutes prior to pessary fitting to help decrease patient discomfort.
• Treat the patient for several weeks with vaginal estrogen cream before attempting to fit a pessary if severe vulvovaginal atrophy is present.

Once the type and size of the pessary are selected and a pessary is inserted, evaluate the patient with the pessary in place. Assess for the following:

Discomfort. Ask the patient if she feels discomfort with the pessary in position. A patient with a properly fitting pessary should not feel that it is in place. If she does feel discomfort initially, the discomfort will only increase with time and the issue should be addressed at that time.

Expulsion. Test to make certain that the pessary is not easily expelled from the vagina. Have the patient walk, cough, squat, and even jump if possible.

Urination. Have the patient urinate with the pessary in place. This tests for her ability to void while wearing the pessary and shows whether the contraction of pelvic muscles during voiding results in expulsion of the pessary. (Experience shows that it is best to do this with a plastic “hat” over the toilet so that if the pessary is expelled, it does not drop into the bowl.)

Re-examination. After these provocative tests, examine the patient again to ensure that the pessary has not slid out of place.

Depending on whether or not your office stocks pessaries, at this point the patient is either given the correct type and size of pessary or it is ordered for her. If the former, the patient should try placing it herself; if she is unable to, the clinician should place it for her. In either event, its position should be checked. If the pessary has to be ordered, the patient must schedule an appointment to return for pessary insertion.

Whether the pessary is supplied by the office or ordered, instruct the patient on how to insert and remove the pessary, how frequently to remove it for cleansing (see below), and signs to watch for, such as vaginal bleeding, inability to void or defecate, or pelvic pain.

It is advisable to schedule a subsequent visit for 2 to 3 weeks after initial pessary placement to assess how the patient is doing and to address any issues that have developed.

Continue to: Special circumstances...

It is safe for a patient with a pessary in place to undergo magnetic resonance imaging.¹ Patients should be informed, however, that full body scans, such as at airports, will detect pessaries. Patients may need to obtain a physician’s note to document that the pessary is a medical device.

Finally, several factors may prevent successful pessary fitting. These include prior pelvic surgery, obesity, short vaginal length (less than 6–7 cm), and a vaginal introitus width of greater than 4 finger breadths.

Necessary pessary aftercare

Once a pessary is in place and the patient is comfortable with it, the only maintenance necessary is the pessary’s intermittent removal for cleansing and for evaluation of the vaginal mucosa for erosion and ulcerations. How frequently this should be done varies based on the type of pessary, the amount of discharge that a woman produces, whether or not an odor develops after prolonged wearing of the pessary, and whether or not the patient’s vaginal mucosa has been abraded.

The question of timing for pessary cleaning

Although there are many opinions about how often pessaries should be removed and cleaned, no data in the literature support any specific interval. Pessaries that are easily removed by women themselves can be cleaned as frequently as desired, often on a weekly basis. The patient simply removes the pessary, washes it with soap and water, and reinserts it. For pessaries that are difficult to remove (such as the Gellhorn, cube, or donut) or for women who are physically unable to remove their own ring pessary, the clinician should remove and clean the pessary in the office every 3 to 6 months. It has been shown that there is no difference in complications from pessary use with either of these intervals.²

Prior to any vaginal surgical procedure, patients must be instructed to remove their pessary 10 to 14 days beforehand so that the surgeon can see the full extent of prolapse when making decisions about reconstruction and so that any vaginal mucosal erosions or abrasions have time to heal.

Office visits for follow-up care

The pessary “cleaning visit” has several goals, including to:

• see if the pessary is meeting the patient’s needs in terms of resolving symptoms of prolapse and/or restoring urinary continence
• discuss with the patient any problems she may be having, such as pelvic discomfort or pressure, difficulty voiding or defecating, excessive vaginal discharge, or vaginal odor
• check for vaginal mucosal erosion or ulceration; such vaginal lesions often can be prevented by the prophylactic use of either estrogen vaginal cream twice weekly or the continuous use of an estradiol vaginal ring in addition to the pessary
• evaluate the condition of the pessary itself and clean it with soap and water.

Continue to: Potential complications of pessary use...

The most common complications experienced by pessary users are:

Odor or excessive discharge. Bacterial vaginosis (BV) occurs more frequently in women who use pessaries. The symptoms of BV can be minimized—but unfortunately not totally eliminated—by the prophylactic use of antiseptic vaginal creams or gels, such as metronidazole, clindamycin, Trimo-San (oxyquinoline sulfate and sodium lauryl sulfate), and others. Inserting the gel vaginally once a week can significantly reduce discharge and odor.³

Vaginal mucosal erosion and ulceration. These are treated by removing the pessary for 2 weeks during which time estrogen cream is applied daily or an estradiol vaginal ring is put in place. If no resolution occurs after 2 weeks, the nonhealing vaginal mucosa should be biopsied.

Pressure on the rectum or bladder. If the pessary causes significant discomfort or interferes with voiding function, then either a different size or a different type pessary should be tried

Patients may discontinue pessary use for a variety of reasons. Among these are:

• discomfort
• inadequate improvement of POP or incontinence symptoms
• expulsion of the pessary during daily activities
• the patient’s desire for surgery instead
• worsening of urine leakage
• difficulty inserting or removing the pessary
• damage to the vaginal mucosa
• pain during removal of the pessary in the office.

Pessary effectiveness for POP and SUI symptoms

As might be expected with a device that is available in so many forms and is used to treat varied types of POP and SUI, the data concerning the success rates of pessary use vary considerably. These rates depend on the definition of success, that is, complete or partial control of prolapse and/or incontinence; which devices are being evaluated; and the nature and severity of the POP and/or SUI being treated.

That being said, a review of the literature reveals that the rates of prolapse symptom relief vary from 48% to 92% (TABLE 1).^4-13

As for success in relieving symptoms of incontinence, studies show improvements in from 40% to 77% of patients (TABLE 2).^6,8,14-17

In addition, some studies show a 50% improvement in bowel symptoms (urgency, obstruction, and anal incontinence) with the use of a pessary.^9,18

While surgery has the advantage of being a one-time fix with a very high rate of initial success in correcting both POP and incontinence, surgery also has potential drawbacks:

• It is an invasive procedure with the discomfort and risk of complications any surgery entails.

It behooves all who provide medical care to women to be familiar with them, to know when they might be useful, and to know how to fit and prescribe them. ●

Power morcellators can be safely used for some gynecologic surgeries, according to recent guidance from the Food and Drug Administration, but doing so requires careful patient selection and use of a legally marketed tissue containment system.

The agency noted that physicians should conduct a thorough preoperative screening and that the devices should only be used for hysterectomies and myomectomies. Clinicians should not use the devices in cases involving uterine malignancy or suspected uterine malignancy.

In addition, clinicians should not use morcellators to remove uterine tissue containing suspected fibroids in women older than 50 years or who are postmenopausal. Nor should the devices be used for women who are “candidates for removal of tissue (en bloc) through the vagina or via a minilaparotomy incision,” the agency said.

The safety communication, which was issued on Dec. 29, 2020, updates previous guidance from February 2020. The updated recommendations are consistent with final labeling guidance for laparoscopic power morcellators, also issued by the FDA on Dec. 29.
 

Risk of disease spread

Prior evidence suggests that use of uncontained power morcellators in women with malignant uterine tissue can spread disease.

Even among women who do not have malignant uterine tissue, containment is important. The agency noted an association between uncontained power morcellation and the spread of benign uterine tissue, such as parasitic myomas and disseminated peritoneal leiomyomatosis, which could require additional surgeries.

In 2016, the FDA approved the PneumoLiner, a containment system for isolating uterine tissue that is not suspected of containing cancer.

“While unsuspected cancer can occur at any age, the prevalence of unsuspected cancer in women undergoing hysterectomy for fibroids increases with age such that the benefit-risk profile of using [laparoscopic power morcellators] is worse in older women when compared to younger women,” according to the new labeling guidance. “Also, the surgical technique of en bloc tissue removal eliminates the need to perform morcellation, thereby reducing the risk of iatrogenic dissemination and upstaging of an occult sarcoma. A thorough preoperative screening should be conducted; however, it is important to note that no screening procedure that can reliably detect sarcoma preoperatively has been identified.”

“The FDA will continue to review the latest data and scientific literature on laparoscopic power morcellation, including gathering real-world evidence from patients, providers and others, and encouraging innovation to better detect uterine cancer and develop containment systems for gynecologic surgery,” said Jeffrey Shuren, MD, JD, director of the FDA’s Center for Devices and Radiological Health, in a news release. “The FDA seeks to ensure women and their health care providers are fully informed when considering laparoscopic power morcellators for gynecologic surgeries.”

Having oral sex with more than 10 previous partners was associated with a 4.3 times’ greater likelihood of developing human papillomavirus (HPV)–related oropharyngeal cancer, according to new findings.

The study also found that having more partners in a shorter period (i.e., greater oral sex intensity) and starting oral sex at a younger age were associated with higher odds of having HPV-related cancer of the mouth and throat.

The new study, published online on Jan. 11 in Cancer, confirms previous findings and adds more nuance, say the researchers.

Previous studies have demonstrated that oral sex is a strong risk factor for HPV-related oropharyngeal cancer, which has increased in incidence in recent decades, particularly cancer of the base of the tongue and palatine and lingual tonsils.

“Our research adds more nuance in our understanding of how people acquire oral HPV infection and HPV-related oropharyngeal cancer,” said study author Gypsyamber D’Souza, PhD, professor of epidemiology at the Johns Hopkins Bloomberg School of Public Health, Baltimore. “It suggests that risk of infection is not only from the number of oral sexual partners but that the timing and type of partner also influence risk.”

The results of the study do not change the clinical care or screening of patients, Dr. D’Souza noted, but the study does add context for patients and providers in understanding, “Why did I get HPV-oropharyngeal cancer?” she said.

“We know that people who develop HPV-oropharyngeal cancer have a wide range of sexual histories, but we do not suggest sexual history be used for screening, as many patients have low-risk sexual histories,” she said. “By chance, it only takes one partner who is infected to acquire the infection, while others who have had many partners by chance do not get exposed, or who are exposed but clear the infection.”
 

Reinforces the need for vaccination

Approached for comment, Joseph Califano, MD, physician-in-chief at the Moores Cancer Center and director of the Head and Neck Cancer Center at the University of California, San Diego, noted that similar data have been published before. The novelty here is in the timing and intensity of oral sex. “It’s not new data, but it certainly reinforces what we knew,” he said in an interview.

These new data are not going to change monitoring, he suggested. “It’s not going to change how we screen, because we don’t do population-based screening for oropharyngeal cancer,” Dr. Califano said.

“It does underline the fact that vaccination is really the key to preventing HPV-mediated cancers,” he said.

He pointed out that some data show lower rates of high-risk oral HPV shedding by children who have been appropriately vaccinated.

“This paper really highlights the fact we need to get people vaccinated early, before sexual debut,” he said. “In this case, sexual debut doesn’t necessarily mean intercourse but oral sex, and that’s a different concept of when sex starts.”

These new data “reinforce the fact that early exposure is what we need to focus on,” he said.
 

Details of the new findings

The current study by Dr. D’Souza and colleagues included 163 patients with HPV-related oropharyngeal cancer who were enrolled in the Papillomavirus Role in Oral Cancer Viral Etiology (PROVE) study. These patients were compared with 345 matched control persons.

All participants completed a behavioral survey and provided a blood sample. For the patients with cancer, a tumor sample was obtained.

The majority of participants were male (85% and 82%), were aged 50-69 years, were currently married or living with a partner, and identified as heterosexual. Case patients were more likely to report a history of sexually transmitted infection than were control participants (P = .003).

Case patients were more likely to have ever performed oral sex compared to control persons (98.8% vs 90.4%; P < .001) and to have performed oral sex at the time of their sexual debut (33.3% of case patients vs 21.4% of control persons; P = .004; odds ratio [OR], 1.8).

Significantly more case patients than control persons reported starting oral sex before they were 18 years old (37.4% of cases vs. 22.6% of controls; P < .001; OR, 3.1), and they had a greater number of lifetime oral sex partners (44.8% of cases and 19.1% of controls reported having more than 10 partners; P < .001; OR, 4.3).

Intensity of oral sexual exposure, which the authors measured by number of partners per 10 years, was also significantly higher among cases than controls (30.8% vs 11.1%; P < .001; OR, 5.6).

After adjustment for confounders (such as the lifetime number of oral sex partners and tobacco use), ever performing oral sex (adjusted odds ratio [aOR], 4.4), early age of first oral sex encounter (20 years: aOR, 1.8), and oral sex intensity (aOR, 2.8) all remained significantly associated with increased odds of HPV-oropharyngeal cancer.

The type of sexual partner, such as partners who were older (OR, 1.7) and having a partner who engaged in extramarital sex (OR, 1.6), were also associated with increased odds of developing HPV-oropharyngeal cancer. In addition, seropositivity for antibodies to HPV16 E6 (OR, 286) and any HPV16 E protein (E1, E2, E6, E7; OR, 163) were also associated with increased odds of developing the disease.

Having oral sex with more than 10 previous partners was associated with a 4.3 times’ greater likelihood of developing human papillomavirus (HPV)–related oropharyngeal cancer, according to new findings.

The study also found that having more partners in a shorter period (i.e., greater oral sex intensity) and starting oral sex at a younger age were associated with higher odds of having HPV-related cancer of the mouth and throat.

The new study, published online on Jan. 11 in Cancer, confirms previous findings and adds more nuance, say the researchers.

Previous studies have demonstrated that oral sex is a strong risk factor for HPV-related oropharyngeal cancer, which has increased in incidence in recent decades, particularly cancer of the base of the tongue and palatine and lingual tonsils.

“Our research adds more nuance in our understanding of how people acquire oral HPV infection and HPV-related oropharyngeal cancer,” said study author Gypsyamber D’Souza, PhD, professor of epidemiology at the Johns Hopkins Bloomberg School of Public Health, Baltimore. “It suggests that risk of infection is not only from the number of oral sexual partners but that the timing and type of partner also influence risk.”

The results of the study do not change the clinical care or screening of patients, Dr. D’Souza noted, but the study does add context for patients and providers in understanding, “Why did I get HPV-oropharyngeal cancer?” she said.

“We know that people who develop HPV-oropharyngeal cancer have a wide range of sexual histories, but we do not suggest sexual history be used for screening, as many patients have low-risk sexual histories,” she said. “By chance, it only takes one partner who is infected to acquire the infection, while others who have had many partners by chance do not get exposed, or who are exposed but clear the infection.”
 

Reinforces the need for vaccination

Approached for comment, Joseph Califano, MD, physician-in-chief at the Moores Cancer Center and director of the Head and Neck Cancer Center at the University of California, San Diego, noted that similar data have been published before. The novelty here is in the timing and intensity of oral sex. “It’s not new data, but it certainly reinforces what we knew,” he said in an interview.

These new data are not going to change monitoring, he suggested. “It’s not going to change how we screen, because we don’t do population-based screening for oropharyngeal cancer,” Dr. Califano said.

“It does underline the fact that vaccination is really the key to preventing HPV-mediated cancers,” he said.

He pointed out that some data show lower rates of high-risk oral HPV shedding by children who have been appropriately vaccinated.

“This paper really highlights the fact we need to get people vaccinated early, before sexual debut,” he said. “In this case, sexual debut doesn’t necessarily mean intercourse but oral sex, and that’s a different concept of when sex starts.”

These new data “reinforce the fact that early exposure is what we need to focus on,” he said.
 

Details of the new findings

The current study by Dr. D’Souza and colleagues included 163 patients with HPV-related oropharyngeal cancer who were enrolled in the Papillomavirus Role in Oral Cancer Viral Etiology (PROVE) study. These patients were compared with 345 matched control persons.

All participants completed a behavioral survey and provided a blood sample. For the patients with cancer, a tumor sample was obtained.

The majority of participants were male (85% and 82%), were aged 50-69 years, were currently married or living with a partner, and identified as heterosexual. Case patients were more likely to report a history of sexually transmitted infection than were control participants (P = .003).

Case patients were more likely to have ever performed oral sex compared to control persons (98.8% vs 90.4%; P < .001) and to have performed oral sex at the time of their sexual debut (33.3% of case patients vs 21.4% of control persons; P = .004; odds ratio [OR], 1.8).

Significantly more case patients than control persons reported starting oral sex before they were 18 years old (37.4% of cases vs. 22.6% of controls; P < .001; OR, 3.1), and they had a greater number of lifetime oral sex partners (44.8% of cases and 19.1% of controls reported having more than 10 partners; P < .001; OR, 4.3).

Intensity of oral sexual exposure, which the authors measured by number of partners per 10 years, was also significantly higher among cases than controls (30.8% vs 11.1%; P < .001; OR, 5.6).

After adjustment for confounders (such as the lifetime number of oral sex partners and tobacco use), ever performing oral sex (adjusted odds ratio [aOR], 4.4), early age of first oral sex encounter (20 years: aOR, 1.8), and oral sex intensity (aOR, 2.8) all remained significantly associated with increased odds of HPV-oropharyngeal cancer.

The type of sexual partner, such as partners who were older (OR, 1.7) and having a partner who engaged in extramarital sex (OR, 1.6), were also associated with increased odds of developing HPV-oropharyngeal cancer. In addition, seropositivity for antibodies to HPV16 E6 (OR, 286) and any HPV16 E protein (E1, E2, E6, E7; OR, 163) were also associated with increased odds of developing the disease.

CASE Unidentified ectopic pregnancy leads to rupture*

A 33-year-old woman (G1 P0010) with 2 positive home pregnancy tests presents to the emergency department (ED) reporting intermittent vaginal bleeding for 3 days. Her last menstrual period was 10 weeks ago, but she reports that her menses are always irregular. She has a history of asymptomatic chlamydia, as well as spontaneous abortion 2 years prior. At present, she denies abdominal pain or vaginal discharge.

Upon examination her vital signs are: temperature, 98.3 °F; pulse, 112 bpm, with a resting rate of 16 bpm; blood pressure (BP), 142/91 mm Hg; pulse O2, 99%; height, 4’ 3”; weight, 115 lb. Her labs are: hemoglobin, 12.1 g/dL; hematocrit, 38%; serum human chorionic gonadotropin (hCG) 236 mIU/mL. Upon pelvic examination, no active bleeding is noted. She agrees to be followed up by her gynecologist and is given a prescription for serum hCG in 2 days. She is instructed to return to the ED should she have pain or increased vaginal bleeding.

Three days later, the patient follows up with her gynecologist reporting mild cramping. She notes having had an episode of heavy vaginal bleeding and a “weakly positive” home pregnancy test. Transvaginal ultrasonography notes endometrial thickness 0.59 mm and unremarkable adnexa. A urine pregnancy test performed in the office is positive; urinalysis is positive for nitrites. With the bleeding slowed, the gynecologist’s overall impression is that the patient has undergone complete spontaneous abortion. She prescribes Macrobid for the urinary tract infection. She does not obtain the ED-prescribed serum HCG levels, as she feels, since complete spontaneous abortion has occurred there is no need to obtain a follow-up serum HCG.

Five days later, the patient returns to the ED reporting abdominal pain after eating. Fever and productive cough of 2 days are noted. The patient states that she had a recent miscarriage. The overall impression of the patient’s condition is bronchitis, and it is noted on the patient’s record, “unlikely ectopic pregnancy and pregnancy test may be false positive,” hence a pregnancy test is not ordered. Examination reveals mild suprapubic tenderness with no rebound; no pelvic exam is performed. The patient is instructed to follow up with a health care clinic within a week, and to return to the ED with severe abdominal pain, higher fever, or any new concerning symptoms. A Zithromax Z-pak is prescribed.

Four days later, the patient is brought by ambulance to the ED of the local major medical center with severe abdominal pain involving the right lower quadrant. She states that she had a miscarriage 3 weeks prior and was recently treated for bronchitis. She has dizziness when standing. Her vital signs are: temperature, 97.8 °F; heart rate, 95 bpm; BP, 72/48 mm Hg; pulse O2, 100%. She reports her abdominal pain to be 6/10.

The patient is given a Lactated Ringer’s bolus of 1,000 mL for a hypotensive episode. Computed tomography is obtained and notes, “low attenuation in the left adnexa with a dilated fallopian tube.” A large heterogeneous collection of fluid in the pelvis is noted with active extravasation, consistent with an “acute bleed.”

The patient is brought to the operating room with a diagnosis of probable ruptured ectopic pregnancy. Intraoperatively she is noted to have a right ruptured ectopic and left tubo-ovarian abscess. The surgeon proceeds with right salpingectomy and left salpingo-oophorectomy. Three liters of hemoperitoneum is found.

She is followed postoperatively with serum hCG until levels are negative. Her postoperative course is uneventful. Her only future option for pregnancy is through assisted reproductive technology (ART) with in vitro fertilization (IVF). The patient sues the gynecologist and second ED physician for presumed inappropriate assessment for ectopic pregnancy.

*The “facts” of this case are a composite, drawn from several cases to illustrate medical and legal issues. The statement of facts should be considered hypothetical.

Continue to: WHAT’S THE VERDICT?...

WHAT’S THE VERDICT?

A defense verdict is returned.

Medical considerations

The incidence of ectopic pregnancy is 2% of all pregnancies, with a higher incidence (about 4%) among infertility patients.¹ Up to 10% of ectopic pregnancies have no symptoms.²

Clinical presentations. Classic signs of ectopic pregnancy include:

• abdominal pain
• vaginal bleeding
• late menses (often noted).

A recent case of ectopic pregnancy presenting with chest pain was reported.³ Clinicians must never lose site of the fact that ectopic pregnancy is the most common cause of maternal mortality in the first trimester, with an incidence of 1% to 10% of all first-trimester deaths.⁴

Risk factors include pelvic inflammatory disease, as demonstrated in the opening case. “The silent epidemic of chlamydia” comes to mind, and tobacco smoking can adversely affect tubal cilia, as can pelvic adhesions and/or prior tubal surgery. All of these factors can predispose a patient to ectopic pregnancy; in addition, intrauterine devices, endometriosis, tubal ligation (or ligation reversal), all can set the stage for an ectopic pregnancy.⁵ Appropriate serum hCG monitoring during early pregnancy can assist in sorting out pregnancies of unknown location (PUL; FIGURE). First trimester ultrasonography, at 5 weeks gestation, usually identifies early intrauterine gestation.

Heterotopic pregnancy includes an intrauterine gestation and an ectopic pregnancy. This presentation includes the presence of a “pseudosac” in the endometrial cavity plus an extrauterine gestation. Heterotopic pregnancies have become somewhat more common as ART/IVF has unfolded, especially prior to the predominance of single embryo transfer.

Managing ectopic pregnancy

For cases of early pregnancy complicated by intermittent bleeding and/or pain, monitoring with serum hCG levels at 48-hour intervals to distinguish a viable IUP from an abnormal IUP or an ectopic is appropriate. The “discriminatory zone” collates serum hCG levels with findings on ultrasonography. Specific lower limits of serum hCG levels are not clear cut, with recommendations of 3,500 mIU/mL to provide sonographic evidence of an intrauterine gestation “to avoid misdiagnosis and possible interruption of intrauterine pregnancy,” as conveyed in the American College of Obstetricians and Gynecologists 2018 practice bulletin.⁸ Serum progesterone levels also have been suggested to complement hCG levels; a progesterone level of <20 nmol/L is consistent with an abnormal pregnancy, whereas levels >25 nmol/L are suggestive of a viable pregnancy.² Inhibin A levels also have been suggested to be helpful, but they are not an ideal monitoring tool.

While most ectopic pregnancies are located in the fallopian tube, other locations also can be abdominal or ovarian. In addition, cesarean scar ectopic pregnancy can occur and often is associated with delay in diagnosis and greater morbidity due to such delay.⁹ With regard to ovarian ectopic, Spiegelberg criteria are established for diagnosis (TABLE 1).¹⁰

Appropriate management of an ectopic pregnancy is dependent upon the gestational age, serum hCG levels, and imaging findings, as well as the patient’s symptoms and exam findings. Treatment is established in large part on a case-by-case basis and includes, for early pregnancy, expectant management and use of methotrexate (TABLE 2).¹¹ Dilation and curettage may be used to identify the pregnancy’s location when the serum hCG level is below 2,000 mIU/mL and there is no evidence of an IUP on ultrasound. Surgical treatment can include minimally invasive salpingostomy or salpingectomy and, depending on circumstance, laparotomy may be indicated.

Legal perspective

Lawsuits related to ectopic pregnancy are not a new phenomenon. In fact, in 1897, a physician in Ohio who misdiagnosed an “extrauterine pregnancy” as appendicitis was the center of a malpractice lawsuit.¹³ Unrecognized or mishandled ectopic pregnancy can result in serious injuries—in the range of 1% to 10% (see above) of maternal deaths are related to ectopic pregnancy.¹⁴ Ectopic pregnancy cases, therefore, have been the subject of substantial litigation over the years. An informal, noncomprehensive review of malpractice lawsuits brought from 2000 to 2019, found more than 300 ectopic pregnancy cases. Given the large number of malpractice claims against ObGyns,¹⁵ ectopic pregnancy cases are only a small portion of all ObGyn malpractice cases.¹⁶

A common claim: negligent diagnosis or treatment

The most common basis for lawsuits in cases of ectopic pregnancy is the clinician’s negligent failure to properly diagnose the ectopic nature of the pregnancy. There are also a number of cases claiming negligent treatment of an identified ectopic pregnancy. Not every missed diagnosis, or unsuccessful treatment, leads to liability, of course. It is only when a diagnosis or treatment fails to meet the standard of care within the profession that there should be liability. That standard of care is generally defined by what a reasonably prudent physician would do under the circumstances. Expert witnesses, who are familiar with the standard of practice within the specialty, are usually necessary to establish what that practice is. Both the plaintiff and the defense obtain experts, the former to prove what the standard of care is and that the standard was not met in the case at hand. The defense experts are usually arguing that the standard of care was met.¹⁷ Inadequate diagnosis of ectopic pregnancy or other condition may arise from a failure to take a sufficient history, conduct an appropriately thorough physical examination, recognize any of the symptoms that would suggest it is present, use and conduct ultrasound correctly, or follow-up appropriately with additional testing.¹⁸

A malpractice claim of negligent treatment can involve any the following circumstances¹⁹:

• failure to establish an appropriate treatment plan
• prescribing inappropriate medications for the patient (eg, methotrexate, when it is contraindicated)
• delivering the wrong medication or the wrong amount of the right medication
• performing a procedure badly
• undertaking a new treatment without adequate instruction and preparation.

Given the nature and risks of ectopic pregnancy, ongoing, frequent contact with the patient is essential from the point at which the condition is suspected. The greater the risk of harm (probability or consequence), the more careful any professional ought to be. Because ectopic pregnancy is not an uncommon occurrence, and because it can have devastating effects, including death, a reasonably prudent practitioner would be especially aware of the clinical presentations discussed above.²⁰ In the opening case, the treatment plan was not well documented.

Negligence must lead to patient harm. In addition to negligence (proving that the physician did not act in accordance with the standard of care), to prevail in a malpractice case, the plaintiff-patient must prove that the negligence caused the injury, or worsened it. If the failure to make a diagnosis would not have made any difference in a harm the patient suffered, there are no damages and no liability. Suppose, for example, that a physician negligently failed to diagnose ectopic pregnancy, but performed surgery expecting to find the misdiagnosed condition. In the course of the surgery, however, the surgeon discovered and appropriately treated the ectopic pregnancy. (A version of this happened in the old 19th century case mentioned above.) The negligence of the physician did not cause harm, so there are no damages and no liability.

Continue to: Informed consent is vital...

Informed consent is vital

A part of malpractice is informed consent (or the absence of it)—issues that can arise in any medical care.²¹ It is wise to pay particular attention in cases where the nature of the illness is unknown, and where there are significant uncertainties and the nature of testing and treatment may change substantially over a period of a few days or few weeks. As always, informed consent should include a discussion of what process or procedure is proposed, its risks and benefits, alternative approaches that might be available, and the risk of doing nothing. Frequently, the uncertainty of ectopic pregnancy complicates the informed consent process.²²

Because communication with the patient is an essential function of informed consent, the consent process should productively be used in PUL and similar cases to inform the patient about the uncertainty, and the testing and (nonsurgical) treatment that will occur. This is an opportunity to reinforce the message that the patient must maintain ongoing communication with the physician’s office about changes in her condition, and appear for each appointment scheduled. If more invasive procedures—notably surgery—become required, a separate consent process should be completed, because the risks and considerations are now meaningfully different than when treatment began. As a general matter, any possible treatment that may result in infertility or reduced reproductive capacity should specifically be included in the consent process.

In the hypothetical case, the gynecologist failed to obtain a follow-up serum hCG level. In addition, the record did not reflect ectopic pregnancy in the differential diagnosis. As noted above, the patient had predisposing factors for an ectopic pregnancy. The physician should have acknowledged the history of sexually transmitted disease predisposing her to an ectopic pregnancy. Monitoring of serum hCG levels until they are negative is appropriate with ectopic, or presumed ectopic, pregnancy management. Appropriate monitoring did not occur in this case. Each of these errors (following up on serum hCG levels and the inadequacy of notations about the possibility of ectopic pregnancy) seem inconsistent with the usual standard of care. Furthermore, as a result of the outcome, the only future option for the patient to pursue pregnancy was IVF.

Other legal issues

There are a number of other legal issues that are associated with the topic of ectopic pregnancy. There is evidence, for example, that Catholic and non-Catholic hospitals treat ectopic pregnancies differently,²³ which may reflect different views on taking a life or the use of methotrexate and its association with abortion.²⁴ In addition, the possibility of an increase in future ectopic pregnancies is one of the “risks” of abortion that pro-life organizations have pushed to see included in abortion informed consent.²⁵ This has led some commentators to conclude that some Catholic hospitals violate federal law in managing ectopic pregnancy. There is also evidence of “overwhelming rates of medical misinformation on pregnancy center websites, including a link between abortion and ectopic pregnancy.”²⁶

The fact that cesarean deliveries are related to an increased risk for ectopic pregnancy (because of the risk of cesarean scar ectopic pregnancy) also has been cited as information that should play a role in the consent process for cesarean delivery.²⁷ In terms of liability, failed tubal ligation leads to a 33% risk of ectopic pregnancy.²⁸ The risk of ectopic pregnancy is also commonly included in surrogacy contracts.²⁹

Why the outcome was for the defense

The opening hypothetical case illustrates some of the uncertainties of medical malpractice cases. As noted, there appeared a deviation from the usual standard of care, particularly the failure to follow up on the serum hCG level. The weakness in the medical record, failing to note the possibility of ectopic pregnancy, also was probably an error but, apparently, the court felt that this did not result in any harm to the patient.

The question arises of how there would be a defense verdict in light of the failure to track consecutive serum hCG levels. A speculative explanation is that there are many uncertainties in most lawsuits. Procedural problems may result in a case being limited, expert witnesses are essential to both the plaintiff and defense, with the quality of their review and testimony possibly uneven. Judges and juries may rely on one expert witness rather than another, juries vary, and the quality of advocacy differs. Any of these situations can contribute to the unpredictability of the outcome of a case. In the case above, the liability was somewhat uncertain, and the various other factors tipped in favor of a defense verdict. ●

In fact, in 1897, a physician in Ohio who misdiagnosed an “extrauterine pregnancy” as appendicitis was the center of a malpractice lawsuit.¹³ Unrecognized or mishandled ectopic pregnancy can result in serious injuries—in the range of 1% to 10% (see above) of maternal deaths are related to ectopic pregnancy.¹⁴ Ectopic pregnancy cases, therefore, have been the subject of substantial litigation over the years. An informal, noncomprehensive review of malpractice lawsuits brought from 2000 to 2019, found more than 300 ectopic pregnancy cases. Given the large number of malpractice claims against ObGyns,¹⁵ ectopic pregnancy cases are only a small portion of all ObGyn malpractice cases.¹⁶

A common claim: negligent diagnosis or treatment

The most common basis for lawsuits in cases of ectopic pregnancy is the clinician’s negligent failure to properly diagnose the ectopic nature of the pregnancy. There are also a number of cases claiming negligent treatment of an identified ectopic pregnancy. Not every missed diagnosis, or unsuccessful treatment, leads to liability, of course. It is only when a diagnosis or treatment fails to meet the standard of care within the profession that there should be liability. That standard of care is generally defined by what a reasonably prudent physician would do under the circumstances. Expert witnesses, who are familiar with the standard of practice within the specialty, are usually necessary to establish what that practice is. Both the plaintiff and the defense obtain experts, the former to prove what the standard of care is and that the standard was not met in the case at hand. The defense experts are usually arguing that the standard of care was met.¹⁷ Inadequate diagnosis of ectopic pregnancy or other condition may arise from a failure to take a sufficient history, conduct an appropriately thorough physical examination, recognize any of the symptoms that would suggest it is present, use and conduct ultrasound correctly, or follow-up appropriately with additional testing.¹⁸

A malpractice claim of negligent treatment can involve any the following circumstances¹⁹:

• failure to establish an appropriate treatment plan
• prescribing inappropriate medications for the patient (eg, methotrexate, when it is contraindicated)
• delivering the wrong medication or the wrong amount of the right medication
• performing a procedure badly
• undertaking a new treatment without adequate instruction and preparation.

Given the nature and risks of ectopic pregnancy, ongoing, frequent contact with the patient is essential from the point at which the condition is suspected. The greater the risk of harm (probability or consequence), the more careful any professional ought to be. Because ectopic pregnancy is not an uncommon occurrence, and because it can have devastating effects, including death, a reasonably prudent practitioner would be especially aware of the clinical presentations discussed above.²⁰ In the opening case, the treatment plan was not well documented.

Negligence must lead to patient harm. In addition to negligence (proving that the physician did not act in accordance with the standard of care), to prevail in a malpractice case, the plaintiff-patient must prove that the negligence caused the injury, or worsened it. If the failure to make a diagnosis would not have made any difference in a harm the patient suffered, there are no damages and no liability. Suppose, for example, that a physician negligently failed to diagnose ectopic pregnancy, but performed surgery expecting to find the misdiagnosed condition. In the course of the surgery, however, the surgeon discovered and appropriately treated the ectopic pregnancy. (A version of this happened in the old 19th century case mentioned above.) The negligence of the physician did not cause harm, so there are no damages and no liability.

Informed consent is vital

A part of malpractice is informed consent (or the absence of it)—issues that can arise in any medical care.²¹ It is wise to pay particular attention in cases where the nature of the illness is unknown, and where there are significant uncertainties and the nature of testing and treatment may change substantially over a period of a few days or few weeks. As always, informed consent should include a discussion of what process or procedure is proposed, its risks and benefits, alternative approaches that might be available, and the risk of doing nothing. Frequently, the uncertainty of ectopic pregnancy complicates the informed consent process.²²

Because communication with the patient is an essential function of informed consent, the consent process should productively be used in PUL and similar cases to inform the patient about the uncertainty, and the testing and (nonsurgical) treatment that will occur. This is an opportunity to reinforce the message that the patient must maintain ongoing communication with the physician’s office about changes in her condition, and appear for each appointment scheduled. If more invasive procedures—notably surgery—become required, a separate consent process should be completed, because the risks and considerations are now meaningfully different than when treatment began. As a general matter, any possible treatment that may result in infertility or reduced reproductive capacity should specifically be included in the consent process.

In the hypothetical case, the gynecologist failed to obtain a follow-up serum hCG level. In addition, the record did not reflect ectopic pregnancy in the differential diagnosis. As noted above, the patient had predisposing factors for an ectopic pregnancy. The physician should have acknowledged the history of sexually transmitted disease predisposing her to an ectopic pregnancy. Monitoring of serum hCG levels until they are negative is appropriate with ectopic, or presumed ectopic, pregnancy management. Appropriate monitoring did not occur in this case. Each of these errors (following up on serum hCG levels and the inadequacy of notations about the possibility of ectopic pregnancy) seem inconsistent with the usual standard of care. Furthermore, as a result of the outcome, the only future option for the patient to pursue pregnancy was IVF.

Other legal issues

There are a number of other legal issues that are associated with the topic of ectopic pregnancy. There is evidence, for example, that Catholic and non-Catholic hospitals treat ectopic pregnancies differently,²³ which may reflect different views on taking a life or the use of methotrexate and its association with abortion.²⁴ In addition, the possibility of an increase in future ectopic pregnancies is one of the “risks” of abortion that pro-life organizations have pushed to see included in abortion informed consent.²⁵ This has led some commentators to conclude that some Catholic hospitals violate federal law in managing ectopic pregnancy. There is also evidence of “overwhelming rates of medical misinformation on pregnancy center websites, including a link between abortion and ectopic pregnancy.”²⁶

The fact that cesarean deliveries are related to an increased risk for ectopic pregnancy (because of the risk of cesarean scar ectopic pregnancy) also has been cited as information that should play a role in the consent process for cesarean delivery.²⁷ In terms of liability, failed tubal ligation leads to a 33% risk of ectopic pregnancy.²⁸ The risk of ectopic pregnancy is also commonly included in surrogacy contracts.²⁹

Why the outcome was for the defense

The opening hypothetical case illustrates some of the uncertainties of medical malpractice cases. As noted, there appeared a deviation from the usual standard of care, particularly the failure to follow up on the serum hCG level. The weakness in the medical record, failing to note the possibility of ectopic pregnancy, also was probably an error but, apparently, the court felt that this did not result in any harm to the patient.

The question arises of how there would be a defense verdict in light of the failure to track consecutive serum hCG levels. A speculative explanation is that there are many uncertainties in most lawsuits. Procedural problems may result in a case being limited, expert witnesses are essential to both the plaintiff and defense, with the quality of their review and testimony possibly uneven. Judges and juries may rely on one expert witness rather than another, juries vary, and the quality of advocacy differs. Any of these situations can contribute to the unpredictability of the outcome of a case. In the case above, the liability was somewhat uncertain, and the various other factors tipped in favor of a defense verdict. ●

CASE Unidentified ectopic pregnancy leads to rupture*

A 33-year-old woman (G1 P0010) with 2 positive home pregnancy tests presents to the emergency department (ED) reporting intermittent vaginal bleeding for 3 days. Her last menstrual period was 10 weeks ago, but she reports that her menses are always irregular. She has a history of asymptomatic chlamydia, as well as spontaneous abortion 2 years prior. At present, she denies abdominal pain or vaginal discharge.

Upon examination her vital signs are: temperature, 98.3 °F; pulse, 112 bpm, with a resting rate of 16 bpm; blood pressure (BP), 142/91 mm Hg; pulse O2, 99%; height, 4’ 3”; weight, 115 lb. Her labs are: hemoglobin, 12.1 g/dL; hematocrit, 38%; serum human chorionic gonadotropin (hCG) 236 mIU/mL. Upon pelvic examination, no active bleeding is noted. She agrees to be followed up by her gynecologist and is given a prescription for serum hCG in 2 days. She is instructed to return to the ED should she have pain or increased vaginal bleeding.

Three days later, the patient follows up with her gynecologist reporting mild cramping. She notes having had an episode of heavy vaginal bleeding and a “weakly positive” home pregnancy test. Transvaginal ultrasonography notes endometrial thickness 0.59 mm and unremarkable adnexa. A urine pregnancy test performed in the office is positive; urinalysis is positive for nitrites. With the bleeding slowed, the gynecologist’s overall impression is that the patient has undergone complete spontaneous abortion. She prescribes Macrobid for the urinary tract infection. She does not obtain the ED-prescribed serum HCG levels, as she feels, since complete spontaneous abortion has occurred there is no need to obtain a follow-up serum HCG.

Five days later, the patient returns to the ED reporting abdominal pain after eating. Fever and productive cough of 2 days are noted. The patient states that she had a recent miscarriage. The overall impression of the patient’s condition is bronchitis, and it is noted on the patient’s record, “unlikely ectopic pregnancy and pregnancy test may be false positive,” hence a pregnancy test is not ordered. Examination reveals mild suprapubic tenderness with no rebound; no pelvic exam is performed. The patient is instructed to follow up with a health care clinic within a week, and to return to the ED with severe abdominal pain, higher fever, or any new concerning symptoms. A Zithromax Z-pak is prescribed.

Four days later, the patient is brought by ambulance to the ED of the local major medical center with severe abdominal pain involving the right lower quadrant. She states that she had a miscarriage 3 weeks prior and was recently treated for bronchitis. She has dizziness when standing. Her vital signs are: temperature, 97.8 °F; heart rate, 95 bpm; BP, 72/48 mm Hg; pulse O2, 100%. She reports her abdominal pain to be 6/10.

The patient is given a Lactated Ringer’s bolus of 1,000 mL for a hypotensive episode. Computed tomography is obtained and notes, “low attenuation in the left adnexa with a dilated fallopian tube.” A large heterogeneous collection of fluid in the pelvis is noted with active extravasation, consistent with an “acute bleed.”

The patient is brought to the operating room with a diagnosis of probable ruptured ectopic pregnancy. Intraoperatively she is noted to have a right ruptured ectopic and left tubo-ovarian abscess. The surgeon proceeds with right salpingectomy and left salpingo-oophorectomy. Three liters of hemoperitoneum is found.

She is followed postoperatively with serum hCG until levels are negative. Her postoperative course is uneventful. Her only future option for pregnancy is through assisted reproductive technology (ART) with in vitro fertilization (IVF). The patient sues the gynecologist and second ED physician for presumed inappropriate assessment for ectopic pregnancy.

*The “facts” of this case are a composite, drawn from several cases to illustrate medical and legal issues. The statement of facts should be considered hypothetical.

WHAT’S THE VERDICT?

A defense verdict is returned.

Medical considerations

The incidence of ectopic pregnancy is 2% of all pregnancies, with a higher incidence (about 4%) among infertility patients.¹ Up to 10% of ectopic pregnancies have no symptoms.²

Clinical presentations. Classic signs of ectopic pregnancy include:

• abdominal pain
• vaginal bleeding
• late menses (often noted).

A recent case of ectopic pregnancy presenting with chest pain was reported.³ Clinicians must never lose site of the fact that ectopic pregnancy is the most common cause of maternal mortality in the first trimester, with an incidence of 1% to 10% of all first-trimester deaths.⁴

Risk factors include pelvic inflammatory disease, as demonstrated in the opening case. “The silent epidemic of chlamydia” comes to mind, and tobacco smoking can adversely affect tubal cilia, as can pelvic adhesions and/or prior tubal surgery. All of these factors can predispose a patient to ectopic pregnancy; in addition, intrauterine devices, endometriosis, tubal ligation (or ligation reversal), all can set the stage for an ectopic pregnancy.⁵ Appropriate serum hCG monitoring during early pregnancy can assist in sorting out pregnancies of unknown location (PUL; FIGURE). First trimester ultrasonography, at 5 weeks gestation, usually identifies early intrauterine gestation.

Heterotopic pregnancy includes an intrauterine gestation and an ectopic pregnancy. This presentation includes the presence of a “pseudosac” in the endometrial cavity plus an extrauterine gestation. Heterotopic pregnancies have become somewhat more common as ART/IVF has unfolded, especially prior to the predominance of single embryo transfer.

Managing ectopic pregnancy

For cases of early pregnancy complicated by intermittent bleeding and/or pain, monitoring with serum hCG levels at 48-hour intervals to distinguish a viable IUP from an abnormal IUP or an ectopic is appropriate. The “discriminatory zone” collates serum hCG levels with findings on ultrasonography. Specific lower limits of serum hCG levels are not clear cut, with recommendations of 3,500 mIU/mL to provide sonographic evidence of an intrauterine gestation “to avoid misdiagnosis and possible interruption of intrauterine pregnancy,” as conveyed in the American College of Obstetricians and Gynecologists 2018 practice bulletin.⁸ Serum progesterone levels also have been suggested to complement hCG levels; a progesterone level of <20 nmol/L is consistent with an abnormal pregnancy, whereas levels >25 nmol/L are suggestive of a viable pregnancy.² Inhibin A levels also have been suggested to be helpful, but they are not an ideal monitoring tool.

While most ectopic pregnancies are located in the fallopian tube, other locations also can be abdominal or ovarian. In addition, cesarean scar ectopic pregnancy can occur and often is associated with delay in diagnosis and greater morbidity due to such delay.⁹ With regard to ovarian ectopic, Spiegelberg criteria are established for diagnosis (TABLE 1).¹⁰

Appropriate management of an ectopic pregnancy is dependent upon the gestational age, serum hCG levels, and imaging findings, as well as the patient’s symptoms and exam findings. Treatment is established in large part on a case-by-case basis and includes, for early pregnancy, expectant management and use of methotrexate (TABLE 2).¹¹ Dilation and curettage may be used to identify the pregnancy’s location when the serum hCG level is below 2,000 mIU/mL and there is no evidence of an IUP on ultrasound. Surgical treatment can include minimally invasive salpingostomy or salpingectomy and, depending on circumstance, laparotomy may be indicated.

In the case above, the liability was somewhat uncertain, and the various other factors tipped in favor of a defense verdict. ●

The practice of medical students giving unconsented pelvic exams to women patients under anesthesia seems to be continuing, although recent new laws aim to change the situation.

“When I was doing ob.gyn. as a med student, the attending would have me do a pelvic right after the patient was under and before we started surgery,” said one participant in an online forum. “We didn’t exactly get permission but it was for teaching purposes.”

Yet others don’t see what the commotion is about. “There are a hundred things that are done during a surgery that don’t require your specific consent (some of them much more ‘humiliating’ than a pelvic exam). ... There’s not really much left to be shy about during a gyn/rectal/prostate surgery, let me put it that way,” one doctor wrote.

However, many physicians are adamantly opposed to the practice, and laws intended to stop or limit it are being enacted throughout the nation.
 

Renewed concerns have prompted new state laws

A few states have required consent for pelvic exams for many years, beginning with California in 2003. But up until 2019, providing pelvic exams without informed consent was illegal in only six states.

Continuing reports of unauthorized pelvic exams indicate that the practice has not disappeared. University of Michigan professor Maya M. Hammoud, MD, past president of the Association of Professors of Gynecology and Obstetrics, and many others attribute renewed interest in the issue to a 2018 article in the journal Bioethics by Phoebe Friesen, a medical ethicist at McGill University, Montreal, that laid out the ethical arguments against the practice.

Starting in 2019, an outpouring of new state bills have been introduced, and nine more states have passed laws. In addition, 14 other states considered similar bills but did not pass them, in some cases because teaching institutions argued that they were already dealing with the issue. This happened in Connecticut and Massachusetts, after representatives of Yale University, New Haven, Conn., met with legislators.

Laws against the practice have been passed by 15 states, including California, Florida, Illinois, and New York. Some teaching institutions have recently been clamping down on the practice, while many teaching physicians insist that at this point, it has all but ended.
 

A practice that may still continue

For many years, ethicists, women’s rights groups, state legislators, and organized medicine have been trying to eliminate the practice of unauthorized pelvic exams by medical students. Several key medical groups have come out against it, including the American Medical Association, the Association of American Medical Colleges, and the American College of Obstetricians and Gynecologists.

“Fifteen years ago, studies found a substantial number of cases, but my sense is that most of that has stopped,” said Dr. Hammoud. 

Yet despite these changes, there are some disturbing signs that the practice persists.

“I don’t have data, but anecdotally I see it still going on,” said Peter Ubel, MD, a professor at Duke University, Durham, N.C., who was involved in one of those early studies. “Every so often when I’m making a speech, a medical student tells me about performing a pelvic exam without getting permission.

“Perhaps in some cases the attending [physician] did get permission and didn’t tell the medical student, but that would also be a problem,” Dr. Ubel said. “The medical student should be informed that permission was given. This helps them be sensitive to the need to get consent.”

In a 2019 survey of medical students, 92% said they performed a pelvic exam on an anesthetized female patient, and of those, 61% did so without explicit patient consent.

The survey – involving 101 medical students at seven U.S. medical schools – also found that 11% of the medical students said they were extremely uncomfortable with the practice. But nearly one-third of the medical students said that opting out might jeopardize their grades and future careers.

“I tried to opt out once from doing a pelvic exam when I hadn’t met the patient beforehand,” one of them wrote. “The resident told me no.”
 

Some physicians defend the practice

Why do many medical students and doctors think that getting consent for pelvic exams is not necessary?

Some argue that patients implicitly give consent when they walk through the doors of a teaching hospital. “Sorry, but you inherently agree to that when you’re seen in an academic teaching hospital,” wrote one participant in a Student Doctor Network forum. “You agree to have residents and medical students participate in your care, not just an attending. If you just want an attending, then you are free to go to a nonteaching hospital. That’s the deal.”

Others argued that since the anesthetized patient couldn’t feel what was going on, it shouldn’t matter. “Things like pelvic exams, rectal exams, or even heroic trauma surgery occur for training purposes when there is no memory, no sensation and no harm to be done [and] society gains a better practitioner of the art of medicine,” a physician in Columbus, Ohio, wrote on Quora, an online forum.

Some doctors argue that they don’t ask for specific consent when they touch a variety of other body parts, and pelvic exams should be no different. Pelvic exams are needed before surgery of the pelvic area, but they have also been given to women undergoing surgery in a different part of the body.

In 2019 a woman told Deseret News in Utah that she had been recovering from stomach surgery when a resident physician mentioned something she had noticed “when we looked at your cervix.” When she asked why the physician had examined her cervix to prepare for stomach surgery, “no one could give her a good answer.”
 

A ‘positive goal’ doesn’t make it okay

What is missing in many defenses of the practice is any recognition that genitals are the most intimate part of the body, and that a patient’s desire for privacy ought to come first. In a survey of women undergoing gynecologic surgery, 72% expected to be asked for consent before medical students undertook pelvic examinations under anesthesia.

Overruling patients’ concerns about their own privacy is unethical, said Eli Y. Adashi, MD, professor of medical science and former dean of medicine and biological sciences at Brown University, Providence, R.I.

Dr. Adashi said the principle of patient autonomy in medical ethics directs that patients must be involved in decision-making about their care – even when caretakers are pursuing a positive goal, such as helping to educate future doctors.

“Conducting pelvic exams on unconscious women without their specific consent is simply untenable and never has been tenable, and it ought to be discontinued if it hasn’t been already,” says Dr. Adashi, who wrote an opinion piece on the issue for JAMA.

Furthermore, it has been shown that ignoring the need to get consent for pelvic exams makes physicians less concerned about getting patient consent in general. A study led by Dr. Ubel found that medical students who had completed an ob.gyn. clerkship thought getting patients’ consent was significantly less important than those who had not completed that clerkship.
 

Why give pelvic exams to anesthetized women?

Despite the controversy, a number of medical educators continue to direct medical students to perform pelvic exams on anesthetized women. Why is that?

“Pelvic exams are not easy to do,” Dr. Hammoud said. “Learners need to keep working on them; they have to do a lot of them in order to do them well.”

To teach pelvic exams, most medical schools provide standardized patients – paid volunteers who submit to exams and critique the medical student’s work afterwards – but these encounters are limited because of their cost, says Guy Benrubi, MD, professor and emeritus chair of the department of obstetrics and gynecology at the University of Florida, Jacksonville.

He said teaching programs therefore need to supplement exams on standardized patients with exams on unpaid volunteers who provide consent. Programs prefer anesthetized patients, Dr. Benrubi said, because they are easier for novices to work on. “With patients under anesthesia, the muscles are relaxed and it’s easier for learners to detect organs. All the same, you need to get consent.”
 

Teaching institutions stiffen consent requirements

Faced with growing opposition to pelvic exams without consent, teaching institutions as well as gynecologic educators have recently been tightening their policies.

Dr. Hammoud said she has always informed patients orally about the possibility of medical students performing pelvic exams on them, but now some institutions, including her own, want a more involved process. The university recently began consent in writing for pelvic exams.

In addition, the university also now requires that medical students meet patients before performing pelvic exams and that teaching physicians explain the students’ involvement.

Dr. Hammoud said some institutions now require a separate consent form for pelvic exams, but the University of Michigan simply directs that the possibility of the patient getting a pelvic exam be part of the consent form.

This requirement, called “explicit consent,” was endorsed by APGO. It differs from having a separate consent form for pelvic exams, which would highlight the possibility of a pelvic exam, as many women’s rights activists are calling for.

Why not have a separate form? Dr. Hammoud is concerned that it would unnecessarily alarm patients. “When you point out a certain issue, you’re in effect saying to the patient that this is not normal,” she said, noting that, when asked for consent to do the exams, most women agree to it.
 

New wave of state laws prompted by renewed concerns

Dr. Hammoud thinks the laws are unnecessary. “These laws are excessive for the vast majority of physicians who practice ethically. The profession should come up with its own standards rather than having a plethora of laws.”

Several of the more recent laws have a broader scope than the original laws. The original laws simply state that medical students or physicians must get informed consent, but they did not stipulate how informed consent should be obtained. (The laws also typically prohibit pelvic exams when surgery will be in a different area of the body.)

The new laws often follow this format, but some go well beyond it. Some also apply to rectal exams (Maine and Maryland), to men as well as women (Utah and Maryland) requires separate consent (Utah), and require consent for all pelvic exams (Florida). 
 

The struggle over Florida’s law

The original Florida bill was drafted in 2019 by state Sen. Lauren Book, a Democrat who is a victims’ rights advocate working with women who have undergone sexual trauma. In written comments for this article, she says not getting consent for pelvic exams is still going on.

“This disturbing practice is commonplace at medical schools and teaching hospitals across the country – including several Florida universities, based on accounts from current and former medical students and faculty,” Sen. Book stated. “At best, these exams have been wrongful learning experiences for medical students or at worst, the equivalent of a sexual assault.”

Dr. Ubel took exception to linking the teaching activities to sexual assault. “I understand why many women would be horrified by this practice, but it’s not as bad as it seems,” he said. “There is nothing sexual or prurient about these exams, and they are motivated purely by a desire to teach people to be better doctors. That said, patients have the right to say, ‘I don’t want it done to me.’ ” 

In early 2020, Dr. Benrubi was part of a coalition of medical groups that was trying to influence Sen. Book’s bill as it went through the legislature. Sen. Book’s original bill was relatively mild, “but then, late in the process, it was changed into a more sweeping bill with some unclear language,” he said.

The final version was passed and signed into law by Gov. Ron DeSantis, a conservative Republican, in June.

Dr. Benrubi said that a large number of state legislators, including Sen. Book, have been agreeable to fixing the bill. This was supposed to happen in a special session in the fall, but that never materialized, and so the fix will have to wait until the regular session in early 2021.

“The law should not apply to patients undergoing routine pelvic exams,” Dr. Benrubi said. “It should only apply to women patients under anesthesia.”

But while organized medicine wants to walk back the law, Dr. Book wants to expand it. “This upcoming session, I look forward to working with physicians to continue to hone this new law, and to work toward inclusion for males. Everyone has a right to consent.”

The practice of medical students giving unconsented pelvic exams to women patients under anesthesia seems to be continuing, although recent new laws aim to change the situation.

“When I was doing ob.gyn. as a med student, the attending would have me do a pelvic right after the patient was under and before we started surgery,” said one participant in an online forum. “We didn’t exactly get permission but it was for teaching purposes.”

Yet others don’t see what the commotion is about. “There are a hundred things that are done during a surgery that don’t require your specific consent (some of them much more ‘humiliating’ than a pelvic exam). ... There’s not really much left to be shy about during a gyn/rectal/prostate surgery, let me put it that way,” one doctor wrote.

However, many physicians are adamantly opposed to the practice, and laws intended to stop or limit it are being enacted throughout the nation.
 

Renewed concerns have prompted new state laws

A few states have required consent for pelvic exams for many years, beginning with California in 2003. But up until 2019, providing pelvic exams without informed consent was illegal in only six states.

Continuing reports of unauthorized pelvic exams indicate that the practice has not disappeared. University of Michigan professor Maya M. Hammoud, MD, past president of the Association of Professors of Gynecology and Obstetrics, and many others attribute renewed interest in the issue to a 2018 article in the journal Bioethics by Phoebe Friesen, a medical ethicist at McGill University, Montreal, that laid out the ethical arguments against the practice.

Starting in 2019, an outpouring of new state bills have been introduced, and nine more states have passed laws. In addition, 14 other states considered similar bills but did not pass them, in some cases because teaching institutions argued that they were already dealing with the issue. This happened in Connecticut and Massachusetts, after representatives of Yale University, New Haven, Conn., met with legislators.

Laws against the practice have been passed by 15 states, including California, Florida, Illinois, and New York. Some teaching institutions have recently been clamping down on the practice, while many teaching physicians insist that at this point, it has all but ended.
 

A practice that may still continue

For many years, ethicists, women’s rights groups, state legislators, and organized medicine have been trying to eliminate the practice of unauthorized pelvic exams by medical students. Several key medical groups have come out against it, including the American Medical Association, the Association of American Medical Colleges, and the American College of Obstetricians and Gynecologists.

“Fifteen years ago, studies found a substantial number of cases, but my sense is that most of that has stopped,” said Dr. Hammoud. 

Yet despite these changes, there are some disturbing signs that the practice persists.

“I don’t have data, but anecdotally I see it still going on,” said Peter Ubel, MD, a professor at Duke University, Durham, N.C., who was involved in one of those early studies. “Every so often when I’m making a speech, a medical student tells me about performing a pelvic exam without getting permission.

“Perhaps in some cases the attending [physician] did get permission and didn’t tell the medical student, but that would also be a problem,” Dr. Ubel said. “The medical student should be informed that permission was given. This helps them be sensitive to the need to get consent.”

In a 2019 survey of medical students, 92% said they performed a pelvic exam on an anesthetized female patient, and of those, 61% did so without explicit patient consent.

The survey – involving 101 medical students at seven U.S. medical schools – also found that 11% of the medical students said they were extremely uncomfortable with the practice. But nearly one-third of the medical students said that opting out might jeopardize their grades and future careers.

“I tried to opt out once from doing a pelvic exam when I hadn’t met the patient beforehand,” one of them wrote. “The resident told me no.”
 

Some physicians defend the practice

Why do many medical students and doctors think that getting consent for pelvic exams is not necessary?

Some argue that patients implicitly give consent when they walk through the doors of a teaching hospital. “Sorry, but you inherently agree to that when you’re seen in an academic teaching hospital,” wrote one participant in a Student Doctor Network forum. “You agree to have residents and medical students participate in your care, not just an attending. If you just want an attending, then you are free to go to a nonteaching hospital. That’s the deal.”

Others argued that since the anesthetized patient couldn’t feel what was going on, it shouldn’t matter. “Things like pelvic exams, rectal exams, or even heroic trauma surgery occur for training purposes when there is no memory, no sensation and no harm to be done [and] society gains a better practitioner of the art of medicine,” a physician in Columbus, Ohio, wrote on Quora, an online forum.

Some doctors argue that they don’t ask for specific consent when they touch a variety of other body parts, and pelvic exams should be no different. Pelvic exams are needed before surgery of the pelvic area, but they have also been given to women undergoing surgery in a different part of the body.

In 2019 a woman told Deseret News in Utah that she had been recovering from stomach surgery when a resident physician mentioned something she had noticed “when we looked at your cervix.” When she asked why the physician had examined her cervix to prepare for stomach surgery, “no one could give her a good answer.”
 

A ‘positive goal’ doesn’t make it okay

What is missing in many defenses of the practice is any recognition that genitals are the most intimate part of the body, and that a patient’s desire for privacy ought to come first. In a survey of women undergoing gynecologic surgery, 72% expected to be asked for consent before medical students undertook pelvic examinations under anesthesia.

Overruling patients’ concerns about their own privacy is unethical, said Eli Y. Adashi, MD, professor of medical science and former dean of medicine and biological sciences at Brown University, Providence, R.I.

Dr. Adashi said the principle of patient autonomy in medical ethics directs that patients must be involved in decision-making about their care – even when caretakers are pursuing a positive goal, such as helping to educate future doctors.

“Conducting pelvic exams on unconscious women without their specific consent is simply untenable and never has been tenable, and it ought to be discontinued if it hasn’t been already,” says Dr. Adashi, who wrote an opinion piece on the issue for JAMA.

Furthermore, it has been shown that ignoring the need to get consent for pelvic exams makes physicians less concerned about getting patient consent in general. A study led by Dr. Ubel found that medical students who had completed an ob.gyn. clerkship thought getting patients’ consent was significantly less important than those who had not completed that clerkship.
 

Why give pelvic exams to anesthetized women?

Despite the controversy, a number of medical educators continue to direct medical students to perform pelvic exams on anesthetized women. Why is that?

“Pelvic exams are not easy to do,” Dr. Hammoud said. “Learners need to keep working on them; they have to do a lot of them in order to do them well.”

To teach pelvic exams, most medical schools provide standardized patients – paid volunteers who submit to exams and critique the medical student’s work afterwards – but these encounters are limited because of their cost, says Guy Benrubi, MD, professor and emeritus chair of the department of obstetrics and gynecology at the University of Florida, Jacksonville.

He said teaching programs therefore need to supplement exams on standardized patients with exams on unpaid volunteers who provide consent. Programs prefer anesthetized patients, Dr. Benrubi said, because they are easier for novices to work on. “With patients under anesthesia, the muscles are relaxed and it’s easier for learners to detect organs. All the same, you need to get consent.”
 

Teaching institutions stiffen consent requirements

Faced with growing opposition to pelvic exams without consent, teaching institutions as well as gynecologic educators have recently been tightening their policies.

Dr. Hammoud said she has always informed patients orally about the possibility of medical students performing pelvic exams on them, but now some institutions, including her own, want a more involved process. The university recently began consent in writing for pelvic exams.

In addition, the university also now requires that medical students meet patients before performing pelvic exams and that teaching physicians explain the students’ involvement.

Dr. Hammoud said some institutions now require a separate consent form for pelvic exams, but the University of Michigan simply directs that the possibility of the patient getting a pelvic exam be part of the consent form.

This requirement, called “explicit consent,” was endorsed by APGO. It differs from having a separate consent form for pelvic exams, which would highlight the possibility of a pelvic exam, as many women’s rights activists are calling for.

Why not have a separate form? Dr. Hammoud is concerned that it would unnecessarily alarm patients. “When you point out a certain issue, you’re in effect saying to the patient that this is not normal,” she said, noting that, when asked for consent to do the exams, most women agree to it.
 

New wave of state laws prompted by renewed concerns

Dr. Hammoud thinks the laws are unnecessary. “These laws are excessive for the vast majority of physicians who practice ethically. The profession should come up with its own standards rather than having a plethora of laws.”

Several of the more recent laws have a broader scope than the original laws. The original laws simply state that medical students or physicians must get informed consent, but they did not stipulate how informed consent should be obtained. (The laws also typically prohibit pelvic exams when surgery will be in a different area of the body.)

The new laws often follow this format, but some go well beyond it. Some also apply to rectal exams (Maine and Maryland), to men as well as women (Utah and Maryland) requires separate consent (Utah), and require consent for all pelvic exams (Florida). 
 

The struggle over Florida’s law

The original Florida bill was drafted in 2019 by state Sen. Lauren Book, a Democrat who is a victims’ rights advocate working with women who have undergone sexual trauma. In written comments for this article, she says not getting consent for pelvic exams is still going on.

“This disturbing practice is commonplace at medical schools and teaching hospitals across the country – including several Florida universities, based on accounts from current and former medical students and faculty,” Sen. Book stated. “At best, these exams have been wrongful learning experiences for medical students or at worst, the equivalent of a sexual assault.”

Dr. Ubel took exception to linking the teaching activities to sexual assault. “I understand why many women would be horrified by this practice, but it’s not as bad as it seems,” he said. “There is nothing sexual or prurient about these exams, and they are motivated purely by a desire to teach people to be better doctors. That said, patients have the right to say, ‘I don’t want it done to me.’ ” 

In early 2020, Dr. Benrubi was part of a coalition of medical groups that was trying to influence Sen. Book’s bill as it went through the legislature. Sen. Book’s original bill was relatively mild, “but then, late in the process, it was changed into a more sweeping bill with some unclear language,” he said.

The final version was passed and signed into law by Gov. Ron DeSantis, a conservative Republican, in June.

Dr. Benrubi said that a large number of state legislators, including Sen. Book, have been agreeable to fixing the bill. This was supposed to happen in a special session in the fall, but that never materialized, and so the fix will have to wait until the regular session in early 2021.

“The law should not apply to patients undergoing routine pelvic exams,” Dr. Benrubi said. “It should only apply to women patients under anesthesia.”

But while organized medicine wants to walk back the law, Dr. Book wants to expand it. “This upcoming session, I look forward to working with physicians to continue to hone this new law, and to work toward inclusion for males. Everyone has a right to consent.”
