Is diagnostic hysteroscopy safe in patients with type 2 endometrial cancer?
Among women with type 2 endometrial cancer, diagnostic hysteroscopy may not be associated with increased odds of positive peritoneal cytology at the time of surgical staging or with decreased survival, according to a retrospective study of 127 patients.
a researcher said at the meeting sponsored by AAGL, held virtually this year.
Possible associations between cytology and procedures
Prior research has found that positive peritoneal cytology may correlate with greater likelihood of death among patients with endometrial cancer, and researchers have wondered whether pressure on the uterine cavity during hysteroscopy increases the presence of positive peritoneal cytology. “According to some systematic reviews ... it seems that it does,” said study author Luiz Brito, MD, PhD, associate professor of obstetrics and gynecology at the University of Campinas in Brazil.
Nevertheless, research suggests that “most of the time hysteroscopy does not have a powerful impact on the prognosis of these patients,” he said.
Studies have tended to focus on patients with type 1 endometrial cancer, however. Type 2 endometrial cancer, which is more aggressive, “is scarcely studied,” Dr. Brito said. One retrospective study that focused on type 2 endometrial cancer included 140 patients. Among patients who underwent hysteroscopy, 30% had positive cytology. In comparison, 12% of patients in the curettage group had positive cytology. But the difference in disease-specific survival between groups was not statistically significant, and about 33% of the patients in each group developed a recurrence.
To examine associations between diagnostic methods and outcomes in another group of patients with type 2 endometrial cancer, Dr. Brito and colleagues analyzed data from a hospital registry in Brazil.
The database included 1,183 patients with endometrial cancer between 2002 and 2017, including 235 patients with type 2 endometrial cancer. After excluding patients with synchronous tumor and those who did not undergo surgery or did not have peritoneal cytology performed, 127 patients remained for the analysis. The study included follow-up to December 2019.
The researchers compared the prevalence of positive peritoneal cytology among 43 patients who underwent hysteroscopy with that among 84 patients who underwent curettage. The groups had similar baseline characteristics.
Positive peritoneal cytology was more common in the curettage group than in the hysteroscopy group (10.7% vs. 4.6%), although the difference was not statistically significant. Lymphovascular invasion and advanced surgical staging were more common in the curettage group.
In a multivariate analysis, older age and advanced cancer staging were the only factors associated with decreased disease-free survival. Age, advanced cancer staging, and vascular invasion were associated with decreased disease-specific survival.
The researchers also had considered factors such as peritoneal cytology, diagnostic method, age of menarche, menopause time, parity, comorbidities, smoking status, body mass index, abnormal uterine bleeding, histological type, and adjuvant treatment.
A limitation of the study is that it relied on data from a public health system that often has long wait times for diagnosis and treatment, Dr. Brito noted.
Some doctors may forgo cytology
The available research raises questions about the role and relevance of peritoneal cytology in caring for patients with endometrial cancer, René Pareja, MD, a gynecologic oncologist at Instituto Nacional de Cancerología, Bogotá, Colombia, said in a discussion following the presentation.
Peritoneal cytology has not been part of endometrial cancer staging since 2009, Dr. Pareja said. Still, guidelines recommend that surgeons collect cytology during surgical staging, with the idea that the results could inform adjuvant treatment decisions.
“Peritoneal cytology is recommended in the guidelines, but there are no recommendations on how to proceed if it is positive,” Dr. Pareja said. “While some gynecologic oncologists continue to take cytology during endometrial cancer staging, some have stopped doing so. And in Colombia, most of us are not performing pelvic cytology.”
Although some studies indicate that hysteroscopy may increase the rate of positive cytology, positive cytology may not be associated with worse oncological outcomes independent of other risk factors for recurrence, said Dr. Pareja.
So far, studies have been retrospective. Furthermore, the sensitivity and specificity of pelvic cytology tests are not 100%. “Should we continue performing pelvic cytology given the results of this and other studies?” Dr. Pareja asked.
Despite limited knowledge about this variable, physicians may want to be aware if a patient has positive cytology, Dr. Brito suggested. “At least it will give us some red flags so we can be attentive to these patients.”
If researchers were to design a prospective study that incorporates hysteroscopic variables, it could provide more complete answers about the relationship between hysteroscopy and peritoneal cytology and clarify the importance of positive cytology, Dr. Brito said.
Dr. Brito had no relevant disclosures. Dr. Pareja disclosed consulting for Johnson & Johnson.

Cervical cancer recurrence patterns differ after laparoscopic and open hysterectomy
When cervical cancer recurs after radical hysterectomy, the likelihood of recurrence at certain sites and the timing of recurrence may be associated with the surgical approach, according to a retrospective study.
according to a propensity-matched analysis of data from 105 patients with recurrence.
And recurrence in the pelvic cavity and peritoneal carcinomatosis were more common after laparoscopic hysterectomy than after open surgery. Overall survival was similar between the groups, however.
The different patterns of recurrence may relate to dissemination of the disease during colpotomy, but the reasons are unknown, study author Giorgio Bogani, MD, PhD, said at the meeting sponsored by AAGL.
To examine patterns of recurrence after laparoscopic and open abdominal radical hysterectomy for cervical cancer, Dr. Bogani of the department of gynecologic surgery at the National Cancer Institute in Milan and colleagues analyzed data from patients with cervical cancer who developed recurrence after surgery at two oncologic referral centers between 1990 and 2018 (Int J Gynecol Cancer. 2020 Jul. doi: 10.1136/ijgc-2020-001381).
The investigators applied a propensity-matching algorithm to reduce possible confounding factors. They matched 35 patients who had recurrence after laparoscopic hysterectomy to 70 patients who had recurrence after open surgery. The groups had similar baseline characteristics.
As in the Laparoscopic Approach to Cervical Cancer (LACC) trial, patients who had minimally invasive surgery were more likely to have a worse disease-free survival, compared with patients who had open surgery, Dr. Bogani said. Patients who underwent laparoscopic radical hysterectomy had a median progression-free survival of 8 months, whereas patients who underwent open abdominal procedures had a median progression-free survival of 15.8 months.
Although vaginal, lymphatic, and distant recurrences were similar between the groups, a greater percentage of patients in the laparoscopic hysterectomy group had recurrence in the pelvic cavity (74% vs. 34%) and peritoneal carcinomatosis (17% vs. 1.5%).
The LACC trial, which found significantly lower disease-free and overall survival with laparoscopic hysterectomy, sent a “shockwave through the gynecologic oncology community” when it was published in 2018, said Masoud Azodi, MD, in a discussion following Dr. Bogani’s presentation.
Researchers have raised questions about that trial’s design and validity, noted Dr. Azodi, director of minimally invasive and robotic surgery at Yale University in New Haven, Conn.
It could be that local recurrences are attributable to surgical technique, rather than to the minimally invasive approach in itself, Dr. Azodi said. Prior studies of laparoscopic hysterectomy for cervical cancer had indicated better surgical outcomes and equivalent oncologic results, relative to open surgery.
Before the LACC trial, Dr. Bogani used the minimally invasive approach for almost all surgeries. Since then, he has performed open surgeries. If he were to use a minimally invasive approach now, it would be in the context of a clinical trial, Dr. Bogani said.
Dr. Bogani and Dr. Azodi had no relevant financial disclosures.

Two-layer vaginal cuff closure may protect against laparoscopic hysterectomy complications
A two-layer vaginal cuff closure during total laparoscopic hysterectomy is associated with fewer postoperative complications, compared with a standard one-layer closure, according to a retrospective study of approximately 3,000 patients.
The difference is driven by fewer vaginal cuff complications among patients whose surgeons used the two-layer technique, said Ann Peters, MD, of Magee-Womens Hospital at the University of Pittsburgh Medical Center.
In light of these findings, Dr. Peters switched to using a two-layer closure. More surgeons may adopt this method, she said at the annual meeting sponsored by AAGL, held virtually this year.
Modifiable factors
Complications after total laparoscopic hysterectomy may be associated with modifiable surgical risk factors such as surgical volume, expertise, and suture material. The method of vaginal cuff closure also plays an important role, but few studies have compared multilayer and single-layer vaginal cuff closure, Dr. Peters said.
To investigate this question, Dr. Peters and colleagues analyzed data from 2,973 women who underwent total laparoscopic hysterectomy for benign indications during a 6-year period at their institution.
The analysis included 1,760 patients (59%) who underwent single-layer closure and 1,213 (41%) who underwent two-layer closure. The closure method was a matter of surgeon preference. Aside from the closure technique, other aspects of the surgeries were standardized.
The primary outcome was the rate of 30-day postoperative complications. Secondary outcomes included vaginal cuff complications during 6 months of follow-up.
The groups generally had similar baseline characteristics, although patients in the two-layer group had lower body mass index and were less likely to use tobacco.
Intraoperative complications and postoperative readmissions did not differ between the groups. The rate of postoperative complications, however, was lower in the two-layer group: 3.5% versus 5.6%. Likewise, the rate of vaginal cuff complications was lower in the two-layer group: 0.9% versus 2.5%.
No instances of vaginal cuff dehiscence or mucosal separation occurred in the two-layer group, whereas 12 cases of dehiscence and 4 cases of mucosal separation occurred in the one-layer group.
Although the study is limited by its retrospective design, the surgeons had similar training and many variables, including the sutures used, were equal or standardized, Dr. Peters noted.
Avoiding rare complications
Grace M. Janik, MD, of Reproductive Specialty Center in Milwaukee, has long theorized that two-layer closure may be beneficial. This study provides data to support that theory, Dr. Janik said in a discussion following the research presentation.
Given that hysterectomy is a common procedure, “any optimization ... has implications for a large number of women,” Dr. Janik said. Although rare outcomes such as dehiscence are difficult to study, the large number of patients in this analysis allowed the investigators to detect differences between the groups.
Studies of vaginal cuff closure have yielded mixed results. For example, various studies have suggested that laparoscopic closure may be inferior to, equal to, or superior to vaginal closure. Together, the findings indicate that “what we are doing is probably more important than the route,” said Dr. Janik.
Along with multilayer closure, the use of delayed absorbable sutures and adequate tissue bites are other factors that may lead to fewer complications, Dr. Janik noted.

Students have similar confidence levels during a simulated laparoscopic vaginal cuff suturing task whether they train with the current standard laparoscopic simulator or a newer gynecology-specific simulator, a randomized trial found.
Participants who trained on the gynecology-specific simulator, known as Essentials in Minimally Invasive Gynecology (EMIG), reported higher confidence scores, but differences between the groups were not statistically significant, a researcher reported at the annual meeting sponsored by AAGL, held virtually this year.
The study compared EMIG with Fundamentals of Laparoscopic Surgery (FLS), a laparoscopic simulator that general surgeons launched in 2004.
In 2018, the American Board of Obstetrics and Gynecology announced an FLS requirement for residents graduating after May 31, 2020. The same year, the AAGL began validating EMIG. AAGL developed the simulator in response to a growing trend for minimally invasive approaches and to provide a training tool geared toward gynecologists, said Emily G. Lin, MD, an obstetrics and gynecology resident at McGaw Medical Center at Northwestern University in Chicago.
A comparison of the two simulators
The simulators use different port placement and operator positioning. The operating fields within the box trainers also differ. In EMIG, laparoscopic tasks take place within a bowl that simulates a confined workspace similar to a pelvis, whereas FLS tasks take place in an open box trainer environment, Dr. Lin said.
To compare students’ self-reported confidence levels after performing a laparoscopic vaginal cuff suturing task after training with EMIG or FLS, Dr. Lin and colleagues conducted a randomized controlled trial.
The researchers recruited 45 participants who were preclinical medical students or premedical college students without prior training experience. Participants were randomized to EMIG or FLS training. After watching instructional videos about their simulator tasks and the vaginal cuff suturing task, they attempted the vaginal cuff suturing task as a pretest.
They then trained for about 2 hours on their assigned simulator. Training for both groups included practicing peg transfer and intracorporeal knot tying. In addition, the EMIG group trained on a running suture task, and the FLS group trained on a ligating loop task.
After training, participants retried the vaginal cuff suturing task. Participants subsequently rated their confidence during each simulation task on a 5-point Likert scale.
Confidence levels on the peg transfer (4.13 with EMIG vs. 4.10 with FLS), intracorporeal knot tying (3.0 with EMIG vs. 2.86 with FLS) and vaginal cuff suturing (2.46 with EMIG vs. 2.05 with FLS) were similar for both groups.
The study was small, included only one training session, and included only three of the five tasks for each simulator because of time and cost constraints, Dr. Lin noted.
Using simulation in residency training
The study was well designed and sheds light on inevitable comparisons between FLS and EMIG, Ido Sirota, MD, MHA, of New York-Presbyterian Queens, said in a discussion following the research presentation.
“The field of medical simulation has developed tremendously in the past decade,” Dr. Sirota said. “The paradigm that used to be common in our field – of see one, do one, teach one – belongs to the past. ... Current trainees need extensive practice on their surgical skills in a simulation setting before” entering the operating room.
A 2017 review found that simulation may be a useful adjunct to residency training.
And in a pilot study, EMIG’s laparoscopic and hysteroscopic simulation systems were considered to have good face validity, Dr. Sirota noted.
Using a gynecology-specific simulation may have advantages.
“In this day and age when we are trying to differentiate ourselves as a subspecialty, there is a great value to developing our own simulation-based curricula to validate our surgical skills during training, as well as for maintenance throughout our career,” Dr. Sirota said. “We as a subspecialty need specific tests tailored to our surgical procedures.”
Dr. Sirota disclosed consulting for Medtronic, Activ Surgical, Heracure, and HT, and he is on the speakers bureau for Medtronic. Dr. Lin had no relevant financial disclosures.

Is a pelvic examination necessary 6 weeks after hysterectomy?
Doctors commonly perform pelvic examinations approximately 6 weeks following hysterectomy to assess the integrity of the vaginal cuff. But this practice may not be necessary if patients do not have symptoms, a study suggests.
“The 6-week posthysterectomy pelvic examination in asymptomatic women may not be necessary, as it neither detected cuff dehiscence nor negated future risk for dehiscence,” Ritchie Mae Delara, MD, said at the meeting sponsored by AAGL, held virtually this year.
Dr. Delara, of the Mayo Clinic in Phoenix, and colleagues conducted a retrospective cohort study of data from more than 2,000 patients to assess the utility of the 6-week posthysterectomy pelvic examination in detecting cuff dehiscence in asymptomatic women.
An unpredictable complication
Vaginal cuff dehiscence is a rare complication of hysterectomy that can occur days or decades after surgery, which makes “identifying an optimal time for cuff evaluation difficult,” Dr. Delara said. “Currently there is neither evidence demonstrating benefit of routine posthysterectomy examination in detecting vaginal cuff dehiscence, nor data demonstrating the best time to perform posthysterectomy examination.”
For their study, which was also published in the Journal of Minimally Invasive Gynecology, the researchers examined data from 2,051 women who underwent hysterectomy at a single institution during a 6-year period. Patients received at least one postoperative evaluation within 90 days of surgery. Examination of the vaginal cuff routinely was performed approximately 6 weeks after hysterectomy. Patients’ posthysterectomy symptoms and pelvic examination findings were recorded.
About 80% of patients were asymptomatic at the 6-week visit.
Asymptomatic patients were more likely to have normal pelvic examination findings, compared with patients with posthysterectomy symptoms (86.4% vs. 54.3%).
In all, 13 patients experienced complete cuff dehiscence. All of them had an intact vaginal cuff at their 6-week examination. Three had symptoms at that time, including vaginal bleeding in one patient and pelvic pain in two patients.
One patient experienced a complete cuff dehiscence that was provoked by intercourse prior to her examination. The patient subsequently developed two additional episodes of dehiscence provoked by intercourse.
Dehiscence may present differently after benign and oncologic hysterectomies, the study indicated.
Eight patients who experienced complete cuff dehiscence after benign hysterectomy had symptoms such as pelvic pain and vaginal bleeding at the time of presentation for dehiscence, which mainly occurred after intercourse.
Five patients who experienced dehiscence after oncologic hysterectomy were more likely to present without symptoms or provocation.
The median time to dehiscence after benign hysterectomy was about 19 weeks, whereas the median time to dehiscence after oncologic hysterectomy was about 81 weeks.
Surgeons should educate patients about symptoms of dehiscence and the potential for events such as coitus to provoke its occurrence, and patients should promptly seek evaluation if symptoms occur, Dr. Delara said.
Patients with risk factors such as malignancy may benefit from continued routine evaluation, she added.
Timely research
The findings may be especially relevant during the COVID-19 pandemic, when states have issued shelter-in-place orders and doctors have increased their use of telemedicine to reduce in-person visits, Dr. Delara noted.
In that sense, the study is “extremely timely” and may inform and support practice changes, commented Emad Mikhail, MD, in a discussion following the research presentation.
Whether the results generalize to other centers, including smaller centers that perform fewer surgeries, is unclear, said Dr. Mikhail, of the University of South Florida, Tampa.
“It takes vision and critical thinking to challenge these traditional practices,” he said. “I applaud Dr. Delara for challenging one of these.”
Dr. Delara and Dr. Mikhail had no relevant disclosures.
