Credentialing and Patient Safety in Robotic Gynecologic Surgery: Changes over the Last Eight Years.

Background and Objectives: Robotic gynecologic surgery has outpaced data showing risks and benefits related to cost, quality outcomes, and patient safety. We aimed to assess how credentialing standards and perceptions of safe use of robotic gynecologic surgery have changed over time. Methods: An anonymous, online survey was distributed in 2013 and in 2021 to attending surgeons and trainees in accredited obstetrics and gynecology residency programs. Results: There were 367 respondents; 265 in 2013 and 102 in 2021. There was a significant increase in robotic platform use from 2013 to 2021. Percentage of respondents who ever having performed a robotic case increased from 48% to 79% and those who performed > 50 cases increased from 25% to 59%. In 2021, a greater percentage of attending physicians reported having formalized protocol for obtaining robotic credentials (93% vs 70%, p = 0.03) and maintaining credentialing (90% vs 27%, p < 0.01). At both time points, most attendings reported requiring proctoring for 1 - 5 cases before independent use. Opinions on the number of cases needed for surgical independence changed from 2013 to 2021. There was an increase in respondents who believed > 20 cases were required (from 58% to 93% of trainees and 29% to 70% of attendings). In 2021, trainees were less likely to report their attendings lacked the skills to safely perform robotic surgery (25% to 6%, p < 0.01). Discussion: Greater experience with robotic platforms and expansion of credentialing processes over time correlated with improved confidence in surgeon skills. Further work is needed to evaluate if current credentialing procedures are sufficient.

Dismantling Structural Barriers: Resident Clinics Refocused on Equity.

Disparities in health by race, ethnicity, and socioeconomic status within obstetrics and gynecology are well described and prompt evaluation for structural barriers. Academic medicine has a historical role in caring for marginalized populations, with medical trainees often serving as first-line clinicians for outpatient care. The ubiquitous approach of concentrating care of marginalized patients within resident and trainee clinics raises ethical questions regarding equity and sends a clear message of value that is internalized by learners and patients. A path forward is elimination of the structural inequities caused by maintenance of clinics stratified by training level, thereby creating an integrated patient pool for trainees and attending physicians alike. In this model, demographic and insurance information is blinded and patient triage is guided by clinical acuity and patient preference alone. To address structural inequities in our health care delivery system, we implemented changes in our department. Our goals were to improve access and patient experience and to send a unified message to our patients, learners, and faculty-our clinical staff, across all training levels, are committed to giving the highest standard of care to all people, regardless of insurance status or ability to pay. Academic medical centers must look internally for structural barriers that contribute to health care disparities within obstetrics and gynecology as we aim to make progress toward equity.

Association of Preoperative Depression and Anxiety With Long-term Opioid Use After Hysterectomy for Benign Indications.

OBJECTIVE: To assess whether preoperative depression or anxiety is associated with increased risk of long-term, postoperative opioid use after hysterectomy among women who are opioid-naïve. METHODS: We conducted an observational cohort study of 289,233 opioid-naïve adult women (18 years or older) undergoing hysterectomy for benign indications from 2010 to 2017 using IBM MarketScan databases. Opioid use and refills in the 180 days after surgery and preoperative depression and anxiety were assessed. Secondary outcomes included 30-day incidence of emergency department visits, readmission, and 180-day incidence of opioid complications. The association of depression and anxiety were compared using inverse-probability of treatment weighted log-binomial and proportional Cox regression. RESULTS: Twenty-one percent of women had preoperative depression or anxiety, and 82% of the entire cohort had a perioperative opioid fill (16% before surgery, 66% after surgery). Although perioperative opioid fills were relatively similar across the two groups (risk ratio [RR] 1.07, 95% CI 1.06-1.07), women with depression or anxiety were significantly more likely to have a postoperative opioid fill at every studied time period (RRs 1.44-1.50). Differences were greater when restricted to persistent use (RRs 1.49-2.61). Although opioid complications were rare, women with depression were substantially more likely to be diagnosed with opioid dependence (hazard ratio [HR] 5.54, 95% CI 4.12-7.44), and opioid use disorder (HR 4.20, 95% CI 1.97-8.96). CONCLUSION: Perioperative opioid fills are common after hysterectomy. Women with preoperative anxiety and depression are more likely to experience persistent use and opioid-related complications.

Predictors of Admission After the Implementation of an Enhanced Recovery After Surgery Pathway for Minimally Invasive Gynecologic Surgery.

BACKGROUND: Enhanced recovery after surgery (ERAS) pathways in gynecologic surgery have been shown to decrease length of stay with no impact on readmission, but no study has assessed predictors of admission in this population. The purpose of this study was to identify predictors of admission after laparoscopic hysterectomy (LH) and robotic-assisted hysterectomy (RAH) performed under an ERAS pathway. METHODS: This is a prospective observational study of women undergoing LH/RAH for benign indications within an ERAS pathway. Data collected included same-day discharge, reason for admission, incidences of urgent clinic and emergency room (ER) visits, readmissions, reoperations, and 9 postulated predictors of admission listed below. Patient demographics, markers of baseline health, and clinical outcomes were compared between groups (ERAS patients discharged on the day of surgery versus admitted) using Fisher exact and Student t tests. Multivariable logistic regression was used to assess the potential risk factors for being admitted, adjusting for age, race, body mass index, American Society of Anesthesiologists (ASA) physical status score, preoperative diagnosis indicative of hysterectomy, preoperative chronic pain, completion of a preprocedure pain-coping skills counseling session, procedure time, and compliance to the ERAS pathway. RESULTS: There were 165 patients undergoing LH/RAH within an ERAS pathway; 93 (56%) were discharged on the day of surgery and 72 were admitted. There were no significant differences in ER visits, readmissions, and reoperations between groups (ER visits: discharged 13% versus admitted 13%, P = .99; 90-day readmission: discharged 4% versus admitted 7%, P = .51; and 90-day reoperation: discharged 4% versus admitted 3%, P = .70). The most common reasons for admission were postoperative urinary retention (n = 21, 30%), inadequate pain control (n = 21, 30%), postoperative nausea and vomiting (n = 7, 10%), and planned admissions (n = 7, 10%). Increased ASA physical status, being African American, and increased length of procedure were significantly associated with an increased risk of admission (ASA physical status III versus ASA physical status I or II: odds ratio [OR], 3.12; 95% confidence interval [CI], 1.36-7.16; P = .007; African American: OR, 2.47; 95% CI, 1.02-5.96; P = .04; and length of procedure, assessed in 30-minute increments: OR, 1.23; 95% CI, 1.02-1.50; P = .04). CONCLUSIONS: We were able to define predictors of admission for patients having LH/RAH managed with an ERAS pathway. Increased ASA physical status, being African American, and increased length of procedure were significantly associated with admission after LH/RAH performed under an ERAS pathway. In addition, the incidences of urgent clinic and ER visits, readmissions, and reoperations within 90 days of surgery were similar for patients who were discharged on the day of surgery compared to those admitted.

Lower endoscopic ultrasound in preoperative evaluation of rectosigmoid endometriosis.

Background and study aims Endometriosis affects a significant proportion of reproductive-aged women and involves the bowel in up to one-third of patients with the condition. Lower endoscopic ultrasound (LEUS) in assessment of endometriosis of the rectosigmoid colon was first described 20 years ago in European populations. The current study aimed to describe the diagnostic characteristics of this imaging modality at a tertiary US referral center in a large cohort and its impact on surgical planning. Patients and methods This was a retrospective cohort study of adult women evaluated for rectosigmoid endometriosis by LEUS at an American tertiary referral center between January 2003 through June 2017. The reference standard for rectosigmoid endometriosis was surgical evaluation regardless of whether tissue was obtained for histologic evaluation. Two separate analyses were run; one comparing EUS to laparoscopic findings and another comparing EUS to histologic findings. Results LEUS demonstrated a positive predictive value (PPV) of 93.8 % (CI:68.1,99.1) and negative predictive value (NPV) of 96.4 % (CI:87.8,99.0) in the diagnosis of rectosigmoid endometriosis. Test sensitivity was 88.2 % (CI:63.6,98.5) and specificity was 98.2 % (CI:90.1,99.9). Overall diagnostic accuracy of the test was 95.8 % (CI:88.1,99.1). Conclusions In this large cohort of women at an American tertiary referral center undergoing evaluation for rectosigmoid endometriosis, LEUS demonstrated high PPV and NPV as well as excellent diagnostic accuracy. In addition, the LEUS findings provided important information to the referring gynecologic surgeon. This minimally-invasive imaging modality should be utilized in preoperative evaluation of women undergoing surgery for suspected or known endometriosis.

Effect of length of hospital stay on infection and readmission after minimally invasive hysterectomy.

OBJECTIVE: To assess the effect of length of hospital stay on postoperative outcomes after minimally invasive hysterectomy. METHODS: A retrospective cohort analysis was conducted of women who underwent minimally invasive hysterectomy (vaginal or laparoscopic) for benign conditions between January 1, 2014 and December 31, 2016, using the American College of Surgeons National Surgical Quality Improvement Program database. Patient information and 30-day outcomes were compared using multivariable logistic regression after adjusting for patient demographics and medical and procedure variables. RESULTS: The analysis included 31 347 patients. Women discharged the day after surgery were more likely to be African-American, older, have prior abdominal surgery, and a higher ASA classification. Prevalence of organ space infection and readmissions were lower in the same day discharge group. No differences between same- and next-day discharge were found for surgical site infection or urinary tract infection (adjusted odds ratios (aORs) 0.83 (95% [CI] 0.65-1.07; P=0.156) and 0.85 (95% CI 0.68-1.06; P=0.151), respectively). Same-day hospital discharge was associated with a reduced chance of readmission (aOR=0.68, 95% CI 0.54-0.87; P=0.002). CONCLUSION: Same-day hospital discharge after minimally invasive hysterectomy lowered the risk of readmission and did not increase the risk of postoperative complications.

Uterine weight and complications after abdominal, laparoscopic, and vaginal hysterectomy.

BACKGROUND: Although uterine size has been a previously cited barrier to minimally invasive hysterectomy, experienced gynecologic surgeons have been able to demonstrate that laparoscopic and vaginal hysterectomy is feasible with increasingly large uteri. By demonstrating that minimally invasive hysterectomy continues to have superior outcomes even with increased uterine weights, opportunity exists to meaningfully decrease morbidity, mortality, and cost associated with abdominal hysterectomy. OBJECTIVE: We sought to determine if there is an association between uterine weight and posthysterectomy complications and if differences in that association exist across vaginal, laparoscopic, and abdominal approaches. STUDY DESIGN: We conducted a cohort study of prospectively collected quality improvement data from the American College of Surgeons National Surgical Quality Improvement Program database, composed of patient information and 30-day postoperative outcomes from >500 hospitals across the United States and targeted data files, which includes additional data on procedure-specific risk factors and outcomes in >100 of those participating hospitals. We analyzed patients undergoing hysterectomy for benign conditions from 2014 through 2015, identified by Current Procedural Terminology code. We excluded patients who had cancer, surgery by a nongynecology specialty, or missing uterine weight. Patients were compared with respect to 30-day postoperative complications and uterine weight, stratified by surgical approach. Bivariable tests and multivariable logistic regression were used for analysis. RESULTS: In all, 27,167 patients were analyzed. After adjusting for potential confounders, including medical and surgical variables, women with 500-g uteri were >30% more likely to have complications compared to women with uteri ≤100 g (adjusted odds ratio, 1.34; 95% confidence interval, 1.17-1.54; P < .0001), women with 750-g uteri were nearly 60% as likely (adjusted odds ratio, 1.58; 95% confidence interval, 1.37-1.82; P < .0001), and women with uteri ≥1000 g were >80% more likely (adjusted odds ratio, 1.85; 95% confidence interval, 1.55-2.21; P < .0001). The incidence of 30-day postsurgical complications was nearly double in the abdominal hysterectomy group (15%) compared to the laparoscopic group (8%). Additionally, for each stratum of uterine weight, abdominal hysterectomy had significantly higher odds of any complication compared to laparoscopic hysterectomy, even after adjusting for potential demographic, medical, and surgical confounders. For uteri <250 g, abdominal hysterectomy had twice the odds of any complication, compared to laparoscopic hysterectomy (adjusted odds ratio, 2.05; 95% confidence interval, 1.80-2.33), and among women with uteri between 250-500 g, abdominal hysterectomy was associated with an almost 80% increase in odds of any complication (adjusted odds ratio, 1.76; 95% confidence interval, 1.41-2.19). Even among women with uteri >500 g, abdominal hysterectomy was still associated with a >30% increased odds of any complication, compared to laparoscopic hysterectomy (adjusted odds ratio, 1.35; 95% confidence interval, 1.07-1.71). CONCLUSION: We found that while uterine weight was an independent risk factor for posthysterectomy complications, abdominal hysterectomy had higher odds of any complication, compared to laparoscopic hysterectomy, even for markedly enlarged uteri. Our study suggests that uterine weight alone is not an appropriate indication for abdominal hysterectomy. We also identified that it is safe to perform larger hysterectomies laparoscopically. Patients may benefit from referral to experienced surgeons who are able to offer laparoscopic hysterectomy even for markedly enlarged uteri.

Comparison of the levonorgestrel-releasing intrauterine system, hysterectomy, and endometrial ablation for heavy menstrual bleeding in a decision analysis model.

BACKGROUND: A better understanding of the relative risks and benefits of common treatment options for abnormal uterine bleeding (AUB) can help providers and patients to make balanced, evidence-based decisions. OBJECTIVES: To provide comparative estimates of clinical outcomes after placement of levonorgestrel-releasing intrauterine system (LNG-IUS), ablation, or hysterectomy for AUB. SEARCH STRATEGY: A PubMED search was done using combinations of search terms related to abnormal uterine bleeding, LNG-IUS, hysterectomy, endometrial ablation, cost-benefit analysis, cost-effectiveness, and quality-adjusted life years. SELECTION CRITERIA: Full articles published in 2006-2016 available in English comparing at least two treatment modalities of interest among women of reproductive age with AUB were included. DATA COLLECTION AND ANALYSIS: A decision tree was generated to compare clinical outcomes in a hypothetical cohort of 100 000 premenopausal women with nonmalignant AUB. We evaluated complications, mortality, and treatment outcomes over a 5-year period, calculated cumulative quality-adjusted life years (QALYs), and conducted probabilistic sensitivity analysis. MAIN RESULTS: Levonorgestrel-releasing intrauterine system had the highest number of QALYs (406 920), followed by hysterectomy (403 466), non-resectoscopic ablation (399 244), and resectoscopic ablation (395 827). Ablation had more treatment failures and complications than LNG-IUS and hysterectomy. Findings were robust in probabilistic sensitivity analysis. CONCLUSIONS: Levonorgestrel-releasing intrauterine system and hysterectomy outperformed endometrial ablation for treatment of AUB.

Cost-effectiveness of treatments for heavy menstrual bleeding.

BACKGROUND: Heavy menstrual bleeding affects up to one third of women in the United States, resulting in a reduced quality of life and significant cost to the health care system. Multiple treatment options exist, offering different potential for symptom control at highly variable initial costs, but the relative value of these treatment options is unknown. OBJECTIVE: The objective of the study was to evaluate the relative cost-effectiveness of 4 treatment options for heavy menstrual bleeding: hysterectomy, resectoscopic endometrial ablation, nonresectoscopic endometrial ablation, and the levonorgestrel-releasing intrauterine system. STUDY DESIGN: We formulated a decision tree evaluating private payer costs and quality-adjusted life years over a 5 year time horizon for premenopausal women with heavy menstrual bleeding and no suspected malignancy. For each treatment option, we used probabilities derived from literature review to estimate frequencies of minor complications, major complications, and treatment failure resulting in the need for additional treatments. Treatments were compared in terms of total average costs, quality-adjusted life years, and incremental cost-effectiveness ratios. Probabilistic sensitivity analysis was conducted to understand the range of possible outcomes if model inputs were varied. RESULTS: The levonorgestrel-releasing intrauterine system had superior quality-of-life outcomes to hysterectomy with lower costs. In a probabilistic sensitivity analysis, levonorgestrel-releasing intrauterine system was cost-effective compared with hysterectomy in the majority of scenarios (90%). Both resectoscopic and nonresectoscopic endometrial ablation were associated with reduced costs compared with hysterectomy but resulted in a lower average quality of life. According to standard willingness-to-pay thresholds, resectoscopic endometrial ablation was considered cost effective compared with hysterectomy in 44% of scenarios, and nonresectoscopic endometrial ablation was considered cost effective compared with hysterectomy in 53% of scenarios. CONCLUSION: Comparing all trade-offs associated with 4 possible treatments of heavy menstrual bleeding, the levonorgestrel-releasing intrauterine system was superior to both hysterectomy and endometrial ablation in terms of cost and quality of life. Hysterectomy is associated with a superior quality of life and fewer complications than either type of ablation but at a higher cost. For women who are unwilling or unable to choose the levonorgestrel-releasing intrauterine system as a first-course treatment for heavy menstrual bleeding, consideration of cost, procedure-specific complications, and patient preferences can guide the decision between hysterectomy and ablation.

The role of simulation and warm-up in minimally invasive gynecologic surgery.

PURPOSE OF REVIEW: The purpose of the review is to update the reader on the current literature and recent studies evaluating the role of simulation and warm-up as part of surgical education and training, and maintenance of surgical skills. RECENT FINDINGS: Laparoscopic and hysteroscopic simulation may improve psychomotor skills, particularly for early-stage learners. However, data are mixed as to whether simulation education is directly transferable to surgical skill. Data are insufficient to determine if simulation can improve clinical outcomes. Similarly, performance of surgical warm-up exercises can improve performance of novice and expert surgeons in a simulated environment, but the extent to which this is transferable to intraoperative performance is unknown. Surgical coaching, however, can facilitate improvements in performance that are directly reflected in operative outcomes. SUMMARY: Simulation-based curricula may be a useful adjunct to residency training, whereas warm-up and surgical coaching may allow for maintenance of skill throughout a surgeon's career. These experiences may represent a strategy for maintaining quality and value in a lower volume surgical setting.

Considerations for minimally invasive gynecologic surgery in obese patients.

PURPOSE OF REVIEW: The purpose is to review the key anatomical and physiological changes in obese patients and their effects on preoperative, intraoperative, and postoperative care and to highlight the best practices to safely extend minimally invasive approaches to obese patients and provide optimal surgical outcomes in this high-risk population. RECENT FINDINGS: Minimally invasive surgery is safe, feasible, and cost-effective for obese patients. Obesity is associated with anatomical and physiological changes in almost all organ systems, which necessitates a multimodal approach and an experienced, multidisciplinary team. Preoperative counseling, evaluation, and optimization of medical comorbidities are critical. The optimal minimally invasive approach is primarily determined by the patient's anatomy and pathology. Specific intraoperative techniques and modifications exist to maximize surgical exposure and panniculus management. Postoperatively, comprehensive medical management can help prevent common complications in obese patients, including hypoxemia, venous thromboembolism, acute kidney injury, hyperglycemia, and prolonged hospitalization. SUMMARY: Given significantly improved patient outcomes, minimally invasive approaches to gynecological surgery should be considered for all obese patients with particular attention given to specific perioperative considerations and appropriate referral to an experienced minimally invasive surgeon.

Peritoneal Washings After Power Morcellation in Laparoscopic Myomectomy: A Pilot Study.

STUDY OBJECTIVE: To evaluate if peritoneal washings of the abdominopelvic cavity during laparoscopic myomectomy can detect leiomyoma cells after power morcellation. DESIGN: Prospective cohort pilot study. SETTING: University of North Carolina Hospitals, an academic, tertiary referral center (Canadian Task Force classification II-2). PATIENTS: Patients undergoing laparoscopic or robotic myomectomy for suspected benign leiomyoma by members of the Minimally Invasive Gynecologic Surgery division between September 2014 and January 2015. INTERVENTION: Washings of the peritoneal cavity were collected at 3 times during surgery: the beginning of the procedure once the peritoneal cavity was accessed laparoscopically, after the myoma was excised and myometrial incision closed, and after uncontained power morcellation. MEASUREMENTS AND MAIN RESULTS: Twenty patients were included in the analysis. The median morcellation time was 16 minutes (range, 2-36). The median specimen weight was 283.5 g (range, 13-935). Cytologic evaluation (ThinPrep with Papanicolaou staining) did not detect any smooth muscle cells. Cell block histology, however, detected spindle cells in 6 postmorcellation samples. Three of these 6 cases also had spindle cells detected on the postmyomectomy closure samples. When performed on the postmorcellation samples, desmin and smooth muscle actin immunostaining were positive, confirming the presence of smooth muscle cells. CONCLUSION: Cell block histology, but not cytology, can detect leiomyoma cells in peritoneal washings after power morcellation. With myomectomy, there is some tissue disruption that seems to cause cell spread even in the absence of morcellation. Further protocol testing might allow peritoneal washings to be used in assessing containment techniques and testing comparative safety of different morcellation methods.

Robotic-assisted laparoscopic removal of cesarean scar ectopic and hysterotomy revision.

A 38-year-old gravida 6 para 2042 woman presented in consultation regarding management of a uterine defect, or "niche," following resolution of a cesarean scar ectopic pregnancy. She had 3 prior losses, followed by in vitro fertilization that resulted in 2 healthy births, both delivered by cesarean. A third in vitro embryo transfer resulted in the cesarean scar ectopic. After consideration of treatment options, she underwent multiple-dose parenteral methotrexate with eventual termination of the ectopic. Magnetic resonance imaging demonstrated a uterine defect, suspected to contain residual pregnancy tissue. Questions considered in her consultation included whether the defect should be repaired and, if so, from a hysteroscopic or laparoscopic approach, as well as her risk of intrauterine scarring, when, or if, it would be safe to pursue another pregnancy, and her subsequent risk of uterine rupture. Literature review regarding cesarean niche was helpful, but did not seem to completely inform this particular clinical scenario. She elected to proceed with robotic-assisted laparoscopic repair. The vesicovaginal space was opened to expose the defect. Dilute vasopressin was injected circumferentially around the defect to help minimize the use of electrosurgery in opening the hysterotomy. Scar overlying the defect was resected and pregnancy tissue removed. The hysterotomy was closed with delayed-absorbable barbed suture, extrapolating technique from laparoscopic myomectomy. The first layer was imbricated with a second, similar to a 2-layer closure in cesarean delivery. Follow-up magnetic resonance imaging revealed resolution of the defect. After several failed attempts at repeat in vitro fertilization, spontaneous pregnancy was achieved 18 months postoperatively. The pregnancy was uncomplicated and she underwent scheduled cesarean delivery of a healthy neonate at 37 weeks' gestation. The lower uterine segment was thick and developed, with no evidence of a dehiscence.
