LAS VEGAS – Laparoscopic endometriosis excision improves quality of life for at least 7 years, even when women have conservative, fertility-sparing surgery, according to a survey study from the University of Pittsburgh.

The work was likely the first to assess long-term outcomes after laparoscopic endometriosis excision with a disease-specific questionnaire, the Endometriosis Health Profile-30 (EHP-30). The findings should reassure both surgeons and patients. “I really feel these results can help us as endometriosis providers” to counsel women, said lead investigator Nicole M. Donnellan, MD, a gynecologic surgeon at the University of Pittsburgh.

Surgery “offers lasting improvement in all quality of life domains ... measured by the EHP-30”: pain; control/powerlessness; emotional well-being; social support; and self-image, with supplemental questions about work, sexual function, and other matters. Because “definitive surgery was not associated with improved outcomes when compared with fertility-sparing surgery ... fertility preservation should continue to be offered as first-line surgery for treatment of symptomatic disease,” Dr. Donnellan and her team concluded at a meeting sponsored by AAGL.

Surgery is the gold standard for endometriosis, but there just hasn’t been much data on long-term outcomes until now, especially with a potent questionnaire like the EHP-30. The gap left surgeons in the lurch on what to tell women how they’ll do, especially because results from previous, shorter, and less-rigorous studies have been mixed. The Pittsburgh results mean that competent surgeons can breathe easier and be confident in telling women what to expect.

The team administered EHP-30 to 61 women before surgery and at 4 weeks postoperatively; 45 patients (74%) had fertility-sparing excisions, 7 (11%) had hysterectomy with adnexa preservation, and 9 (15%) had hysterectomy with bilateral salpingo-oophorectomy. The women were contacted again in 2017 to fill out the survey anywhere from 3 to 7 years after their operation; 45 women agreed, a response rate of 74%.

There was a definitive, statistically significant reduction in scores across all five domains of the survey, both at 4 weeks and out to 7 years, and the improvements did not vary by endometriosis stage or the type of surgery women had.

The overall score – a combination of the five domains – fell from a preoperative median of 50 points out of a possible 100, with 100 being the worst possible score, to a median of about 20 points 4 weeks after surgery, and a median of about 10 points at long-term follow-up. Pain scores fell about the same amount; the greatest improvements were on questions that focused on sense of control and empowerment.

At long-term follow-up, overall scores improved a median of 43 points in women with American Society for Reproductive Medicine stage 1 endometriosis and 28 points among women with stage 4 disease (P = .705). Although the differences were not statistically significant, women with stage 1 disease generally reported the greatest improvements, except on the control and empowerment scale, where women reported the same improvement across all four stages, about 50 points out of 100.

Long-term score improvements were pretty much identical among women who had fertility-sparing surgery and those who had hysterectomies, with, for instance, both groups reporting about a 33-point improvement in pain scores. The two groups separated out only on emotional well-being scores, a 38-point improvement in the hysterectomy group versus 21 points, but the difference was not statistically significant (P = .525).

The long-term results remained the same when eight women who had subsequent gynecologic surgery were excluded.

In the end, the take home is that “all of these women improved,” Dr. Donnellan said.

The investigators didn’t report any disclosures.

LAS VEGAS – It’s the number of uterine incisions and fibroids removed that increase the risk of miscarriage after fibroid treatment, not the type of procedure, according to a review of 252 cases at Northwestern University, Chicago.

Surgeons feel terrible when a woman loses a pregnancy after fibroid treatment, and wonder if they “caused it, or if it was just a bad uterus or a bad initial pathology,” said lead investigator Laura M. Glaser, MD, an ob.gyn. in private practice in Lake Forest, Ill.

Her study, which was presented at a meeting sponsored by AAGL, suggests that miscarriage occurs mostly from complex pathology, as indicated by the number of fibroids and the degree of uterine cutting needed to remove them. The team reviewed outcomes among women who conceived after treatment; 28 had robotic-assisted myomectomies; 208 had open, abdominal myomectomies; and 16 had uterine fibroid embolization (UFE). Miscarriage was defined as pregnancy loss before 24 weeks.

After the researchers adjusted for age, body mass index, and parity, there were no statistically significant differences in miscarriage rates among the three groups (31% after UFE, 29% after robotic myomectomy, and 22% after abdominal myomectomy).

Open cases had the largest dominant fibroid at a mean of 8.5 cm, the most fibroids removed at 4.5, and the highest rate of cavity entry, 42%. Even so, at 22%, open cases were the least likely to miscarry.

Uterine size, specimen weight, time from procedure to pregnancy, and fibroid location didn’t seem to matter otherwise. The only risk factors that reached statistical significance were among women who had myomectomies; an increasing number of uterine cuts (odds ratio, 1.558; P = .004) and fibroids removed (OR, 1.11; P = .033) increased the odds of miscarriage.

More than 40% of women in the UFE group had previous fibroid surgery, versus 5% among women who had myomectomies. UFE women also were far more likely to have had a previous birth (50% versus 17%), but less likely to have subserosal fibroids (13% versus 33%), and their dominant fibroid was a few centimeters smaller.

Subjects were in their mid-30s, on average, with a mean body mass index of about 28 kg/m². Just over 40% of the women who had myomectomies were white, versus 19% of women who had UFE.

There was no outside funding for the work, and the investigators didn’t have any disclosures.

BOSTON – Even partial reduction of liver metastases from malignant small bowel neuroendocrine tumors will help symptoms and improve survival, according to James Howe, MD, director of surgical oncology and endocrine surgery at the University of Iowa, Iowa City.

M. Alexander Otto/MDedge News

“Hepatic cytoreduction is not just to cut down on hormone production” to relieve carcinoid syndrome symptoms, but also “there seems to be a survival benefit,” he said at the annual clinical congress of the American College of Surgeons.

There was a time when it was thought that at least 90% of liver metastases needed to be removed for patients benefit, but it’s become clear that even clearing 70% will help.

It’s important, however, to use parenchymal sparing techniques such as wedge excision, enucleation, and ablation. “We don’t do a lot of right and left hepatectomies anymore,” because patients often live a long time with the disease, many past 10 years, so the goal is management without undo side effects from aggressive treatment. “The key thing with all patients is to avoid morbidity. These patients are going to live a long time if you do not do very much,” Dr. Howe said.

The general surgical approach is to remove the primary neuroendocrine tumor (NET) plus regional lymph nodes; debulk peritoneal disease; cytoreduce liver metastases, and remove the gallbladder, because many patients go on to somatostatin analogs; in 2 years or so, they’ll develop gallstones.

CT is overall the most useful imaging tool for workup. The terminal ileum is the most common location of small bowel NETs, but often “the primary will not be seen,” so “the main thing I look for is mesenteric lymphadenopathy. Liver metastases are even more suspicious.” PET imaging with gallium-labeled somatostatin analogues is also “very good for determining if a lesion is indeed a NET and to determine sites of distant metastases,” Dr. Howe said.

Suspicious findings are followed by surgical exploration, which he usually does by midline incision, the size of which depends on if hepatic cytoreduction is planned. “It’s critically important to palpate the entire small bowel, or you are going to miss lesions. You can feel them quite easily even if they are just 1 or 2 mm,” he said.

Laparoscopy is an option for quicker recovery and other benefits, but the downside is “you are going to miss multifocal disease if you are using metal graspers to feel the small bowel,” and challenging node resection is impossible. One compromise is to do a small incision of a few inches; “you can actually palpate the small bowel through a small incision, and resect a section of bowel through it,” he said.

He saves systemic therapy for patients who progress despite surgery and somatostatin analogues. Everolimus is an option, but the most promising option is lutetium Lu 177 dotatate (Lutathera), approved by the Food and Drug Administration in early 2018 for pancreatic and gastrointestinal NETs.

SAN FRANCISCO – Empiric antibiotic therapy for febrile neutropenia, a common and life-threatening complication of chemotherapy, hasn’t really changed much in 20 years, according to Alison Freifeld, MD, director of the section of oncology infectious diseases at the University of Nebraska, Omaha.

Antibiotic resistance has become a major problem over that time. Multidrug-resistant, gram-negative blood stream infections are not uncommon, particularly with extended-spectrum, beta-lactamase–producing Escherichia coli and Klebsiella pneumoniae. Carbapenemase-producing Enterobacteriaceae are also on the rise, among others.

“Our standard empiric antibiotics” – ceftazidime, cefepime, piperacillin/tazobactam, and carbapenems – “are generally not active against these organisms, putting us in a major dilemma about what to do” with patients who have them, Dr. Freifeld said.

“Our goal at the moment is to unpack this ship, take some of these loads of antibiotics off, and figure out how we can more effectively bridge the gap between risk factors and outcomes, with fewer and more stringently applied targeted antibiotics,” she said at ID Week, an annual scientific meeting on infectious diseases.

Dr. Freifeld shared her advice at the meeting on what to do as that plays out. The main driver is to protect the remaining potency of current antibiotics without sacrificing patient care while also keeping new options in reserve for the sickest patients, so “we do not overuse these precious commodities.”

For one thing, it’s okay to shorten treatment – traditionally around 2 weeks, until the absolute neutrophil count (ANC) tops 500 cells/mcg – once the fever abates and cultures turn negative, even if the ANC remains low.

A recent trial put the approach to the test. A total of 78 patients had their antibiotics stopped after they had been free of fever for 72 hours, with normal vital signs and no other signs of infection; 79 in the control group had usual care, continuing treatment until their ANC recovered.

Early withdrawal shortened treatment by about 3 days and there were no statistically significant differences in mortality, with one death in the short-arm group and three in the long-arm group. Over half of the patients in the short-arm group were neutropenic when antibiotics were discontinued.

Serious adverse events, meanwhile, were far less common in the short-arm group (18 vs. 38). The take-home lesson is that “interventions to shorten duration of empiric antibiotics are safe and effective and important to implement now,” Dr. Freifeld said (Lancet Haematol. 2017 Dec;4(12):e573-83).

Also, “use escalation and deescalation approaches,” she said. The basic idea is to begin with monotherapy – cefepime or piperacillin/tazobactam – in uncomplicated cases, bumped up as necessary, and, in complicated cases, to start with broad, multidrug regimens, deescalated as culture reports and other information comes in (Haematologica. 2013 Dec;98(12):1826-35).

Finally, fluoroquinolone prophylaxis, “once considered the wonder of the world,” Dr. Freifeld said, needs to be limited to the highest-risk patients, particularly those with neutropenia expected to last a week or more. It does seem to lower the rates of fever and bloodstream infections, but recent investigations have shown no mortality benefit, and fluoroquinolone prophylaxis makes patients more likely to be colonized by multidrug-resistant bacteria. Many centers have opted against it, even in higher-risk patients (J Infect. 2018 Jan;76(1):20-37).

Dr. Freifeld serves on a data adjudication committee for Merck, and reported research support from the company.

Serious adverse events, meanwhile, were far less common in the short-arm group (18 vs. 38). The take-home lesson is that “interventions to shorten duration of empiric antibiotics are safe and effective and important to implement now,” Dr. Freifeld said (Lancet Haematol. 2017 Dec;4(12):e573-83).

Also, “use escalation and deescalation approaches,” she said. The basic idea is to begin with monotherapy – cefepime or piperacillin/tazobactam – in uncomplicated cases, bumped up as necessary, and, in complicated cases, to start with broad, multidrug regimens, deescalated as culture reports and other information comes in (Haematologica. 2013 Dec;98(12):1826-35).

Finally, fluoroquinolone prophylaxis, “once considered the wonder of the world,” Dr. Freifeld said, needs to be limited to the highest-risk patients, particularly those with neutropenia expected to last a week or more. It does seem to lower the rates of fever and bloodstream infections, but recent investigations have shown no mortality benefit, and fluoroquinolone prophylaxis makes patients more likely to be colonized by multidrug-resistant bacteria. Many centers have opted against it, even in higher-risk patients (J Infect. 2018 Jan;76(1):20-37).

SAN FRANCISCO – Empiric antibiotic therapy for febrile neutropenia, a common and life-threatening complication of chemotherapy, hasn’t really changed much in 20 years, according to Alison Freifeld, MD, director of the section of oncology infectious diseases at the University of Nebraska, Omaha.

Antibiotic resistance has become a major problem over that time. Multidrug-resistant, gram-negative blood stream infections are not uncommon, particularly with extended-spectrum, beta-lactamase–producing Escherichia coli and Klebsiella pneumoniae. Carbapenemase-producing Enterobacteriaceae are also on the rise, among others.

“Our standard empiric antibiotics” – ceftazidime, cefepime, piperacillin/tazobactam, and carbapenems – “are generally not active against these organisms, putting us in a major dilemma about what to do” with patients who have them, Dr. Freifeld said.

“Our goal at the moment is to unpack this ship, take some of these loads of antibiotics off, and figure out how we can more effectively bridge the gap between risk factors and outcomes, with fewer and more stringently applied targeted antibiotics,” she said at ID Week, an annual scientific meeting on infectious diseases.

Dr. Freifeld shared her advice at the meeting on what to do as that plays out. The main driver is to protect the remaining potency of current antibiotics without sacrificing patient care while also keeping new options in reserve for the sickest patients, so “we do not overuse these precious commodities.”

For one thing, it’s okay to shorten treatment – traditionally around 2 weeks, until the absolute neutrophil count (ANC) tops 500 cells/mcg – once the fever abates and cultures turn negative, even if the ANC remains low.

A recent trial put the approach to the test. A total of 78 patients had their antibiotics stopped after they had been free of fever for 72 hours, with normal vital signs and no other signs of infection; 79 in the control group had usual care, continuing treatment until their ANC recovered.

LAS VEGAS – It would be nice if surgeons could know beforehand how long robotic laparoscopic myomectomies will take, according to Peter Movilla, MD, a minimally invasive gynecologic surgery fellow at Newton (Mass.) Wellesley Hospital.

M. Alexander Otto/MDedge News

Best guesses are sometimes wrong, and it’s not uncommon for robotic cases to go longer than expected, especially when they have to be converted to an open approach.

Among other problems, going long backs up operating room (OR)scheduling and makes families impatient. Also, if it was known beforehand that a robotic case might take 5 hours, patients could be offered a quicker open procedure, especially if they are not good candidates for prolonged pneumoperitoneum.

After a case went past 6 hours at the University of California, San Francisco (UCSF), when Dr. Movilla was an ob.gyn. resident, he wanted to find a better way.

“I saw that we were not the best at guessing how long these surgeries were going to take, and thought maybe we could make prediction a little better by [incorporating] preoperative factors” in a structured way. “I wanted to create something that would give us an answer of how long it will take,” he said at a meeting sponsored by AAGL.

So he and his colleagues reviewed 126 robot-assisted laparoscopic myomectomies at UCSF. The mean operative time from skin incision to closure was 213 minutes, mean specimen weight 264.4 g, mean dominant fibroid diameter 8.5 cm, and mean number of fibroids removed 2.5. Four cases (3%) were converted to open laparotomy.

The team divided the cases by how long they took; 20% were under 3 hours, 70% took 3-5 hours; and 10% went over 5 hours. “Five hours is a long time to be in the OR,” especially when a case could have been done open, Dr. Movilla said.

Length of surgery correlated with 7 of the 21 preoperative factors considered on multivariate logistic regression. Cases tended to be longer in younger women and in women with diabetes, and when surgeons had less experience. There was a trend toward longer cases with higher body mass indices, but it was not statistically significant.

Having three or more fibroids on preoperative imaging and a larger number of fibroids over 3 cm were predictive of operations longer than 3 hours. However, the strongest predictors of long cases were uterine volume and the diameter of the largest fibroid, a mean of 532.4 cm³ and 8.8 cm, respectively, in cases over 5 hours. Posterior and intramural fibroids also increased operative time, but, again, the trends were not statistically significant.

The team put it all together in a risk calculator they tested against their subjects’ actual surgery times. The model tended to underestimate very short and very long cases at either end of the curve, but overall the fit was “not too bad,” and the more cases that are added to the model, the more accurate it will get, Dr. Movilla said.

There was no external funding for the work, and Dr. Movilla had no disclosures.

LAS VEGAS – Lower insufflation pressures were associated with improved patient outcomes and reduced postanesthesia care unit utilization in a review of 598 robot-assisted gynecologic surgery procedures performed at a single center by the same surgeon, said researchers at New York University (NYU) Medical Center.

M. Alexander Otto/MDedge News

Each incremental drop in abdominal insufflation pressure “improved intraoperative and postoperative clinical outcomes” with “faster postoperative recovery times, decreased immediate postoperative pain, and improved intraoperative respiratory parameters, without increasing duration of surgery or blood loss,” said investigator Christine Foley, MD, formerly at NYU, and now a minimally-invasive gynecologic surgery fellow at the University of Pittsburgh.

An abdominal insufflation pressure of 10 mm Hg or less was the sweet spot, she said at the meeting sponsored by AAGL.

The general surgery literature recommends operating at the lowest possible abdominal insufflation pressure to reduce postoperative pain, and that recommendation has been incorporated into enhanced recovery after surgery (ERAS) protocols. Gynecologic surgeons have not routinely followed suit, she noted. “Surgeons should consider operating at lower insufflation pressures to improve patient outcomes and PACU [postanesthesia care unit] utilization. Further research is warranted to determine if lower pressures ... should be included in ERAS protocols” for gynecologic surgery.

There’s not much in the way of data on insufflation pressures in robotic gynecologic surgery. What has been published suggests, as in general surgery, less postop pain, but at the cost of impaired visualization and greater blood loss. At the moment, robotic cases are often done at insufflation pressures above 12 mm Hg.

To get a better grasp of the issue, Dr. Foley and her team reviewed 196 hysterectomies, 275 myomectomies, and 127 endometriosis surgeries at NYU, all performed robotically by the same surgeon for benign indications. Ninety-nine cases were at 15 mm Hg; 100 at 12 mm Hg; 99 at 10 mm Hg, and 300 at 8 mm Hg.

The study did not address why the surgeon opted for different pressures in different cases. The body mass index was a mean of 27 kg/m², and patient age was about 40 years, in all four pressure groups. There were trends for higher pressures with hysterectomies and lower pressures for endometriosis, but also considerable crossover, with more than 40% of the hysterectomies performed at 8 mm Hg, and almost 10% of the endometriosis cases done at 15 mm Hg.

Across the board, patients did better at lower pressures. Each drop in insufflation pressure correlated with a significant decrease in the initial pain score in the PACU (5.9 out of 10 points at 15 mm Hg, 5.4 at 12 mm Hg, 4.4 at 10 mm Hg, and 3.8 at 8 mm Hg, P less than .0001); lower pressures also correlated with shorter PACU stays (449 minutes, 467 minutes, 351 minutes, and 317 minutes, P less than .0001).

Surgery duration was a mean of 70 minutes across all four groups. Estimated blood loss was 114 mL at 15 mm Hg, 97.4 mL at 12 mm Hg, 127 mL 10 mm Hg, and 78.4 mL at 8 mm HG; the differences were not statistically significant. Maximum PACU pain levels favored lower pressures, and lower pressures correlated with significantly lower peak inspiratory pressures and tidal volumes.

The results argue for operating at the lowest possible pressure, Dr. Foley said, but she and her team did not address how their outcomes might have been influenced by the type of surgery the women had.

There was no external funding for the study. Dr. Foley had no relevant financial disclosures.

LAS VEGAS – Vaginal trial of labor is safe after myomectomy, at least if the uterine cavity wasn’t entered, according to investigators from Northwestern University, Chicago.

M. Alexander Otto/MDedge News

The American College of Obstetricians and Gynecologists lists prior myomectomy as a medically-indicated reason for delivery before 39 weeks. The advice reflects a traditional concern that uterine scars will rupture during labor, with potentially devastating consequences for both mother and infant.

Reviews have put the risk at less than 1%, so ob.gyns. have shied away from ACOG’s blanket advice and now use uterine-cavity entry during myomectomy as their talisman for deciding whether or not to offer women vaginal delivery. The assumption is that uterine entry makes rupture more likely, but there’s not much evidence to support that idea, and it’s become clear in recent years that women who have a significant full-thickness insult to uterine integrity – a prior C-section – can usually deliver vaginally with no problem. In short, the uterus seems to have a remarkable ability to heal itself.

Even so, there are still ob.gyns. who pressure women into having premature babies if they’ve had a fibroid removed even without cavity entry. Barring additional indications, that doesn’t happen anymore at Northwestern University, said lead investigator Nathan King, MD, an ob.gyn. resident at the university.

The Northwestern team wanted to clear the fog. What they found adds to “literature that demonstrates the overall low risk of undergoing VTOL [vaginal trial of labor] after a prior myomectomy. We hope providers will feel more comfortable talking to their patients about delivery [options] and the success of VTOL after myomectomy,” Dr. King said at a meeting sponsored by AAGL.*

He and his team analyzed pregnancy outcomes in 112 women who had a live birth after non–cavity-entering myomectomies. Forty-nine women (44%) were allowed to undergo VTOL; 63 others had C-sections, most at term.

Thirty-two VTOL women (65%) had vaginal deliveries, a success rate similar to that of labor after C-section. There was just one uterine rupture in the VTOL group, for an incidence of 2%, which also was comparable to the rupture risk after a low-transverse C-section.

The rupture was discovered after spontaneous vaginal delivery, and an addressed by laparotomy. Both mother and infant were fine.

Adverse events were less likely in the VTOL group, regardless if they ultimately delivered vaginally or by C-section. The lower adverse event rate was driven by fewer postpartum hemorrhages (odds ratio, 0.441, 95% confidence interval, 0.2002-0.9722, P = .042).

There were no demographic difference between women who were allowed to undergo VTOL and those who were not. For most, it was their first delivery.

Women who had their uterine cavities entered during myomectomy weren’t allowed to undergo VTOL at Northwestern, and were not included in the analysis. Also, the study did not include women who became pregnant after myomectomy, but did not have a live delivery. The incidence of uterine rupture among them, if any, was not reported.

There was no external funding for the work, and Dr. King didn’t have any disclosures.

Even so, there are still ob.gyns. who pressure women into having premature babies if they’ve had a fibroid removed even without cavity entry. Barring additional indications, that doesn’t happen anymore at Northwestern University, said lead investigator Nathan King, MD, an ob.gyn. resident at the university.

The Northwestern team wanted to clear the fog. What they found adds to “literature that demonstrates the overall low risk of undergoing VTOL [vaginal trial of labor] after a prior myomectomy. We hope providers will feel more comfortable talking to their patients about delivery [options] and the success of VTOL after myomectomy,” Dr. King said at a meeting sponsored by AAGL.*

He and his team analyzed pregnancy outcomes in 112 women who had a live birth after non–cavity-entering myomectomies. Forty-nine women (44%) were allowed to undergo VTOL; 63 others had C-sections, most at term.

Thirty-two VTOL women (65%) had vaginal deliveries, a success rate similar to that of labor after C-section. There was just one uterine rupture in the VTOL group, for an incidence of 2%, which also was comparable to the rupture risk after a low-transverse C-section.

The rupture was discovered after spontaneous vaginal delivery, and an addressed by laparotomy. Both mother and infant were fine.

Adverse events were less likely in the VTOL group, regardless if they ultimately delivered vaginally or by C-section. The lower adverse event rate was driven by fewer postpartum hemorrhages (odds ratio, 0.441, 95% confidence interval, 0.2002-0.9722, P = .042).

There were no demographic difference between women who were allowed to undergo VTOL and those who were not. For most, it was their first delivery.

Women who had their uterine cavities entered during myomectomy weren’t allowed to undergo VTOL at Northwestern, and were not included in the analysis. Also, the study did not include women who became pregnant after myomectomy, but did not have a live delivery. The incidence of uterine rupture among them, if any, was not reported.

There was no external funding for the work, and Dr. King didn’t have any disclosures.

SAN FRANCISCO – Emergency departments are the ideal place to screen for hepatitis C infection, according to investigators from Vanderbilt University, Nashville, Tenn.

M. Alexander Otto/MDedge News

Current recommendations call for screening baby boomers born from 1945 to 1965 and patients with risk factors, especially injection drug use. The problem is that the guidelines don’t say, exactly, how and where that should be done, so uptake has been spotty. Also, people aren’t exactly forthcoming when it comes to admitting IV drug use.

Enter universal screening in the ED. Vanderbilt is one of several academic centers that have adopted the approach, and others are following suit. Across the board, they’ve found that HCV infection is more common than projections based on baby boomer and risk factor demographics suggest, and, even more importantly, the boomer/risk factor strategy misses a large number of active cases, said Cody A. Chastain, MD, assistant professor of infectious diseases at Vanderbilt, who led the ED screening initiative.

In short, universal screening in the ED would keep people from falling through the cracks.

From April 2017 to March 2018, every adult who had blood drawn at Vanderbilt’s tertiary care ED was asked by a nurse if they’d also like to be checked for HCV, so long as they were alert enough for the conversation. If they agreed, an additional phlebotomy tube was added to the draw, and sent off for testing. Fewer than 5% of patients opted out.

Antibody positive samples were automatically screened for active disease by HCV RNA. Results were entered into the medical record and shared with patients at discharge. Active cases were counseled and offered linkage to care, regardless of insurance status.

The initiative screened 11,637 patients; 1,008 (8.7%) were antibody positive, of whom 488 (48%) were RNA positive. Thirty-seven percent of the active cases were in non–baby boomers – most born after 1965 – with no known injection drug use. The baby boomer/risk factor model would have missed most of them.

Also, spontaneous clearance – antibody positive, RNA negative without HCV treatment – “is dramatically higher” than what’s thought. “The historic estimate of 20% clearly is not reflected” in the Vanderbilt results, nor in similar universal screening studies; “spontaneous clearance is about 50% or so,” Dr. Chastain said.

Even so, “virtually every study published in this space finds more cases of infection than traditional screening would find. [Our work] is just one more piece of data” to indicate the usefulness of the approach. “Emergency departments [are] ideal for hepatitis C screening,” he said at IDWeek, an annual scientific meeting on infectious diseases, where he presented the findings.

“This is well trodden territory; we’ve already addressed it with HIV. We recognized that HIV screening had a stigma and was a challenge, [so we] moved to universal screening” of all adults, at least once. It “drastically improved screening rates. I don’t see a rational reason” not to do this for hepatitis C. “There are very well-meaning people who engage in the cost effectiveness side of this discussion, but I don’t think it helps us in our efforts to control this epidemic from a public health standpoint,” Dr. Chastain said.

Vanderbilt continues to screen for HCV in the ED; the next step is to see how well efforts to link active cases with care are working. Many times during the study, Dr. Chastain said positive patients eventually revealed that they already knew they had HCV, but had been told there was nothing they could do about it, so they didn’t get care. Maybe they were told that because they didn’t have insurance.

Vanderbilt has dropped screening ED patients born before 1945 because the odds of picking up an unknown HCV infection proved to be tiny, and, in any case, patients are generally too comorbid for treatment. It’s made screening more efficient.

Dr. Chastain reported that he had no personal disclosures. The study was funded by Vanderbilt, which receives grants from pharmaceutical companies.

Clear cell renal cell carcinoma (ccRCC) with predominant papillary features is best classified as a rare morphologic variant of ccRCC, not MiT family translocation or papillary RCC, according to an analysis of 23 tumors.

Areas of papillary pattern made up anywhere from 40% to 100% of the 23 tumors. Even so, cytology and immunohistochemical and genetic testing was most consistent with ccRCC, and tumors were negative for TFE3 protein, which ruled out MiT family translocation RCC, reported Reza Alaghehbandan, MD, and his associates. The report is in Annals of Diagnostic Pathology.

The findings help clarify where ccRCC fits in the diagnostic tree when there’s significant papillary morphology, something that hasn’t been clear until now. The proper classification matters because it carries treatment implications; for instance, ccRCC generally responds well to immunotherapy and targeted therapy, but papillary RCC does not, so doctors often recommend treatment through a clinical trial.

“The presence of mixed morphologic components in renal neoplasms in general and in ccRCCs in particular can be puzzling in routine practice, which can potentially lead to misdiagnosis.” Getting it right is “crucial” to ensure the best treatment, said Dr. Alaghehbandan, of the University of British Columbia, Vancouver, and his associates.

Cytokeratin 7 (CK7) staining was negative in the nonpapillary areas of 20 tumors (87%), and only focally positive in three (13%). In contrast, clear cell papillary RCC is strongly and diffusely positive for CK7.

In papillary areas, Alpha-methyl CoA racemase was positive or focally positive in 17 tumors (73.9%); in nonpapillary areas, it was positive or focally positive in 22 (95.6%). Carbonic anhydrase IX was mainly negative in both nonpapillary and papillary areas, while vimentin and CD10 were positive or focally positive in both.

Patients were a mean of 65.2 years old, and 19 were men. The median tumor size was 6.5 cm. At a median follow-up of 2.5 years, two patients had died of their disease, and two had developed metastasis.

There was no industry funding, and the investigators didn’t have any disclosures.

LAS VEGAS – Injecting the cervix with bupivacaine before laparoscopic hysterectomy significantly reduces postoperative pain, according to a small trial at the University of Tennessee, Chattanooga.

M. Alexander Otto/MDedge News

Twenty-one women were randomized to 0.5% bupivacaine, 5 mL injected into the cervix at the 3 o’clock position, and 5 mL injected into at the 9 o’clock position to a depth of 3 cm, after anesthesia induction but before insertion of the uterine manipulator. A control group of 20 women received 5 mL of 0.9% saline injected into the same positions. Surgeons were blinded to the randomization.

A stopwatch was started at extubation, and the women were asked to rate their pain on a 10-point visual analogue scale exactly at 30 and 60 minutes.

The bupivacaine group had less pain at both 30 minutes (3.2 versus 5.7 points, P = .01) and 60 minutes (2.3 versus 5.9 points, P less than .001); 71% of women in the bupivacaine group had an average score of 4 or less, indicating adequate pain control, versus just 25% in the control arm (P = .003)

“This is something we should be considering” routinely for laparoscopic hysterectomy, an audience member said after hearing the presentation at a meeting sponsored by AAGL.

Another audience member was concerned about urinary retention, but there was no increase in the treatment arm, said lead investigator Steven Radtke, MD, a former ob.gyn. surgery fellow at the university, but now at Texas Tech University, El Paso.

There have been many prior attempts to reduce pain after laparoscopic hysterectomy, such as infiltrating port sites with local anesthetic, but the results have been marginal at best, and almost all of them have focused on the abdominal wall as the source of pain.

The investigators thought that pain was more related to perimetrium dissection, colpotomy, and other parts of the operation. There also have been good studies showing that agents injected into the cervix infuse throughout the area. The team decided to try bupivacaine because it’s inexpensive and has a good duration of action, about 8 hours.

There were no significant demographic or intraoperative differences between the groups. On average, women were in their mid-40s, with a body mass index of about 31 kg/m². The operations took about 2 hours, and were for benign indications, such as fibroids. Oophorectomy was the only concomitant procedure allowed.

The investigators are interested in repeating their investigation with liposomal bupivacaine (Exparel), which has a duration of action past 24 hours. It’s much more expensive, but the strong trial results justify the cost, Dr. Radtke said.

There was no external funding, and Dr. Radtke didn’t have any disclosures.
