RESUMO
Small near-infrared (NIR) fluorescent proteins (FPs) are much needed as protein tags for imaging applications. We developed a 17 kDa NIR FP, called miRFP670nano3, which brightly fluoresces in mammalian cells and enables deep-brain imaging. By exploring miRFP670nano3 as an internal tag, we engineered 32 kDa NIR fluorescent nanobodies, termed NIR-Fbs, whose stability and fluorescence strongly depend on the presence of specific intracellular antigens. NIR-Fbs allowed background-free visualization of endogenous proteins, detection of viral antigens, labeling of cells expressing target molecules and identification of double-positive cell populations with bispecific NIR-Fbs against two antigens. Applying NIR-Fbs as destabilizing fusion partners, we developed molecular tools for directed degradation of targeted proteins, controllable protein expression and modulation of enzymatic activities. Altogether, NIR-Fbs enable the detection and manipulation of a variety of cellular processes based on the intracellular protein profile.

PURPOSE OF REVIEW: Chronic pelvic main is a complex process that includes many causes. In gynecology, the treatment of myofascial pelvic pain and high tone pelvic floor disorders can be managed with skeletal muscle relaxants for select clinical indications. A review of skeletal muscle relaxants will be included for gynecologic indications. RECENT FINDINGS: There are limited studies on vaginal skeletal muscle relaxants, but there can be oral forms used for chronic myofascial pelvic pain. They function as antispastic, antispasmodic, and combination of the two modes of action. Diazepam is the most studied for myofascial pelvic pain in both oral and vaginal formulations. Its use can be combined with multimodal management to optimize outcomes. Other medications have limitations due to dependency and limited studies that demonstrate improvement in pain scales. SUMMARY: Skeletal muscle relaxants have limited high quality studies for chronic myofascial pelvic pain. Their use can be combined with multimodal options to improve clinical outcomes. Additional studies are needed for vaginal preparations and evaluation of safety and clinical efficacy for patient reported outcomes measures in patients living with chronic myofascial pelvic pain.

STUDY OBJECTIVE: To examine national trends among race and ethnicity and route of benign hysterectomy from 2007 to 2018. DESIGN: This is a retrospective analysis of the prospective National Surgical Quality Improvement Program cohort program. SETTING: This study included data from the National Surgical Quality Improvement Program database including data from the 2014 to 2018 targeted hysterectomy files. PATIENTS: Adult patients undergoing hysterectomy. INTERVENTIONS: None MEASUREMENTS AND MAIN RESULTS: Current Procedural Terminology codes identified women undergoing benign hysterectomy and perioperative data including race and ethnicity were obtained. To determine relative trends in hysterectomy among race and ethnicity cohorts (White, Black, Hispanic), we calculated the proportion of each procedure performed annually within each race and ethnicity group and compared it across groups. From 2007 to 2018, 269 794 hysterectomies were collected (190 154 White, 45 756 Black, and 33 884 Hispanic). From 2007 to 2018, rates of laparoscopic hysterectomy increased in all cohorts (30.2%-71.6% for White, 23.9%-58.5% for Black, 19.9%-64.0% for Hispanic; ptrend <0.01 for all). For each year from 2007 to 2018, the proportion of women undergoing open abdominal hysterectomy remained twice as high in Black Women compared with White women (33.1%-14.4%, p <.01). Data from the 2014 to 2018 targeted files showed Black and Hispanic women undergoing benign hysterectomy were generally younger, had larger uteri, were more likely to be current smokers, have diabetes and/or hypertension, have higher body mass index, and have undergone previous pelvic surgery (p ≤.01 for all). CONCLUSION: Compared with White women, Black and Hispanic women are less likely to undergo benign hysterectomy via a minimally invasive approach. Although larger uteri and comorbid conditions may attribute to higher rates of open abdominal hysterectomy, the higher prevalence of abdominal hysterectomy among younger Black and Hispanic women highlights potential racial disparities in women's health and access to care.

BACKGROUND: Healthcare disparities research is often limited by incomplete accounting for differences in health status by populations. In the United States, hysterectomy shows marked variation by race and geography, but it is difficult to understand what factors cause these variations without accounting for differences in the severity of gynecologic symptoms that drive the decision-making for hysterectomy. OBJECTIVE: This study aimed to demonstrate a method for using electronic health record-derived data to create composite symptom severity indices to more fully capture relevant markers that influence the decision for hysterectomy. STUDY DESIGN: This was a retrospective cohort study of 1993 women who underwent hysterectomy between April 4, 2014, and December 31, 2017, from 10 hospitals and >100 outpatient clinics in North Carolina. Electronic health record data, including billing, pharmacy, laboratory data, and free-text notes, were used to identify markers of 3 common indications for hysterectomy: bulk symptoms (pressure from uterine enlargement), vaginal bleeding, and pelvic pain. To develop weighted symptom indices, we finalized a scoring algorithm based on the relationship of each marker to an objective measure, in combination with clinical expertise, with the goal of composite symptom severity indices that had sufficient variation to be useful in comparing different patient groups and allow discrimination among severe symptoms of bulk, bleeding, or pain. RESULTS: The ranges of symptom severity scores varied across the 3 indices, including composite bulk score (0-14), vaginal bleeding score (0-44), and pain score (0-30). The mean values of each composite symptom severity index were greater for those who had diagnostic codes for vaginal bleeding, bulk symptoms, or pelvic pain, respectively. However, each index demonstrated a variation across the entire group of hysterectomy cases and identified symptoms that ranged in severity among those with and without the target diagnostic codes. CONCLUSION: Leveraging multisource data to create composite symptom severity indices provided greater discriminatory power to assess common gynecologic indications for hysterectomy. These methods can improve the understanding in healthcare use in the setting of long-standing inequities and be applied across populations to account for previously unexplained variations across race, geography, and other social indicators.

STUDY OBJECTIVE: To assess whether female compared with male sex is associated with greater ergonomic strain with the use of 4 advanced energy laparoscopic devices (LigaSure, HALO PKS, ENSEAL, and Harmonic scalpel). DESIGN: Online survey distributed by e-mail using the REDCap platform (Vanderbilt University). All responses were anonymous. SETTING: Nationwide survey in the United States. PARTICIPANTS: Gynecologic surgeons were surveyed through the Society of Gynecologic Surgeons listserv and 4 obstetrics and gynecology departmental listservs. INTERVENTIONS: The survey was distributed between May 1, 2020, and November 1, 2020. The primary outcome was the presence of physical complaints owing to laparoscopic devices. Descriptive statistics compared surgeon characteristics and ergonomic symptoms. Logistic regression was performed, adjusted for surgeon characteristics. MEASUREMENTS AND MAIN RESULTS: The response rate was 39%, comprising 149 women (78%) and 41 men (22%). Women compared with men had a significantly younger age (mean, 34 vs 44 years; p <.01), had smaller glove size (mean, 6.5 vs 7.5; p <.01), had shorter height (median, 66 vs 71 inches; p <.01), and were less frequently in practice for >10 years (19% vs 49%; p <.01). Women significantly more often reported physical complaints related to the use of laparoscopic devices (79% vs 41%; p <.01). Women reported that all devices had too large a fit for appropriate use (p <.01). Women were found to have 5.37 times the odds of physical complaints attributed to the use of laparoscopic instruments (crude oods ratio, 5.37; 95% confidence interval, 2.56-11.25); with adjustment for glove size, age, and laparoscopic case volume and duration, this was no longer significant (adjusted odds ratio, 2.02; 95% confidence interval, 0.59-6.93). CONCLUSION: Women significantly more often report physical complaints and inappropriate fit of the LigaSure, HALO PKS, ENSEAL, and Harmonic scalpel. Female sex is associated with 5-fold greater odds of physical complaints with laparoscopic device use. Further investigation of the surgeon factors underlying device-related strain is a critical next step to understanding and reducing surgeon ergonomic injury.

STUDY OBJECTIVE: To evaluate whether surgeon characteristics, including sex and hand size, were associated with grip strength decline with laparoscopic advanced energy devices. DESIGN: Prospective cohort study. SETTING: Ergonomic simulation at an academic tertiary care site and the Society of Gynecologic Surgeons 47th Annual Meeting. PATIENTS: Thirty-eight participants (19 women and 19 men) were recruited. INTERVENTIONS: Surgeon anthropometric measurements were collected. Each participant completed a 120-second trial of maximum voluntary effort with 3 laparoscopic advanced energy devices (LigaSure, HALO PKS, and ENSEAL). Grip strength was measured using a handheld dynamometer. Subjects completed the NASA Raw Task Load Index scale after each device trial. Grip strengths and ergonomic workload scores were compared using Student t tests and Wilcoxon rank sum tests where appropriate. Univariate and multivariate models analyzed hand size and ergonomic workload. MEASUREMENTS AND MAIN RESULTS: Women had lower baseline grip strength (288 vs 451 N) than men, as did participants with glove size <7 compared with ≥7 (231 vs 397 N). Normalized grip strength was not associated with surgeon sex (p = .08), whereas it was significantly associated with surgeon glove size (p <.01). Grip strength decline was significantly greater for smaller compared to larger handed surgeons for LigaSure (p = .02) and HALO PKS devices (p <.01). The ergonomic workload of device use was significantly greater for smaller compared to larger handed surgeons (p <.01). Surgeon handspan significantly predicted grip strength decline with device use, even after accounting for potential confounders (R2 = .23, ß = .8, p <.01). CONCLUSION: Surgeons with smaller hand size experienced a greater grip strength decline and greater ergonomic workload during repetitive laparoscopic device use. No relationship was found between surgeon sex and grip strength decline or ergonomic workload. Laparoscopic device type was also identified as a significant main effect contributing to grip strength decline. These findings point toward ergonomic strain stemming from an improper fit between the laparoscopic device and the surgeon's hand during device use.

STUDY OBJECTIVE: In this study, we describe trends of all 3 routes of hysterectomy, patient demographics, and perioperative morbidity among women undergoing surgery for benign indications between 2007 and 2017. We also sought to compare the rates of extended length of stay (ELOS) and readmission rates among the laparoscopic, abdominal, and transvaginal routes. STUDY DESIGN: A retrospective cohort study. STUDY SETTING: National database study. PATIENTS: The American College of Surgeons National Surgical Quality Improvement Program database to identify patients who underwent an elective hysterectomy for benign indication between 2007 and 2017. INTERVENTIONS: Patients were identified using Current Procedural Terminology codes and excluded if their indication for surgery included cancer and pelvic organ prolapse diagnoses based on International Classification of Diseases codes. The collected variables of interest included age, body mass index, American Society of Anesthesiologists classification, uterine weight of >250 grams, and operative time. Our outcomes of interest included ELOS and readmission within 30 days. ELOS was defined as a hospital admission of 2 days or more after laparoscopic and transvaginal hysterectomy and greater than 3 days for an abdominal hysterectomy. Summary statistics were used to evaluate shifts in patient characteristics and postoperative outcomes by hysterectomy route and year of surgery. Multivariable logistic regression analysis, stratified by year, comparing laparoscopic with transvaginal and abdominal hysterectomies was performed. MEASUREMENTS AND MAIN RESULTS: There were 224 357 patients who met the inclusion and exclusion criteria. Of those, 132 567 (59.1%) underwent a laparoscopic hysterectomy, 30 105 (13.4%) a vaginal hysterectomy, and 61 685 (27.5%) an abdominal hysterectomy. The rate of laparoscopic hysterectomy increased by >200% between 2007 and 2017, whereas the rates of transvaginal and abdominal hysterectomies steadily decreased (-58% and -42%, respectively) The mean age, median obesity, and American Society of Anesthesiologists classification increased among women undergoing hysterectomy across all routes with the sharpest increase within the laparoscopic hysterectomy group (% increase in mean age [2.1%, 1.3%, 0.7%] and mean body mass index [9.1%, 4.3%, 3.7%] for laparoscopic, transvaginal, and abdominal routes, respectively). In 2017, the odds of ELOS were 29% lower for those who received laparoscopic than those who received abdominal hysterectomy (p <.001). Comparing the rates of readmission between the laparoscopic and abdominal hysterectomy groups shows that the odds of readmission are significantly lower for patients who receive a laparoscopic hysterectomy across all 11 years (p <.001). CONCLUSION: The rates of laparoscopic hysterectomy have been steadily increasing over the past 11 years. This large retrospective study confirms the lowest rates of readmission and ELOS within the laparoscopic hysterectomy group despite the rising medical complexity of the patients.

STUDY OBJECTIVE: To assess the prevalence of myofascial pain in women undergoing uncomplicated, minimally invasive hysterectomy for chronic pelvic pain, to identify clinical and demographic factors associated with preoperative myofascial pain, and examine the association between myofascial pain and postoperative pain in hysterectomy patients. DESIGN: A retrospective cohort study. SETTING: A tertiary care teaching hospital. PATIENTS: A total of 353 adult women who underwent uncomplicated, minimally invasive hysterectomy between January 2014 and 2016. INTERVENTIONS: All women underwent a preoperative pelvic floor examination. Myofascial pain was diagnosed as tenderness and reproduction of pain symptoms in at least 2 of 6 pelvic floor muscles. Demographics, comorbidities, and intraoperative characteristics were compared between women with and without preoperative myofascial pain. MEASUREMENTS AND MAIN RESULTS: Of the 353 women who underwent hysterectomy, the prevalence of myofascial pain was 42.7% (86.0% in patients with chronic pelvic pain [CPP] compared with 13.7% without CPP). Women with myofascial pain were more likely younger, Caucasian, sexually active, and with comorbid pain conditions. Patients with myofascial pain used a greater number of adjuvant pain medications before surgery including opiates (29.5%) but were only half as likely to use muscle relaxants (12.1%) for preoperative pain control. Contrastingly, in women without myofascial pain before surgery, controlled substances such as opiates (8%, p <.01) and benzodiazepines (3%, p <.01) were used at a three- fold lower frequency. Postoperative pain score was higher in patients with myofascial pain, with 37% reporting a visual analog scale score greater than 5 at the routine postoperative visit compared with only 1% of patients without myofascial pain. CONCLUSION: Myofascial pelvic pain must be considered in the evaluation of CPP, especially in surgical candidates. Women with myofascial pelvic use a greater amount of pain medication preoperatively and have higher pain scores postoperatively. Identification of these high-risk patients before surgery may improve pre and postoperative pain management with a multimodal therapy approach.

STUDY OBJECTIVE: Learning to evaluate and treat chronic pelvic pain (CPP) is an established curriculum objective within the Fellowship in Minimally Invasive Gynecologic Surgery (FMIGS). Our aim was to investigate current educational experiences related to the evaluation and management of CPP and the impacts of those experiences on FMIGS fellows and recent fellowship graduates, including satisfaction, confidence in management, and clinical interest in CPP. DESIGN: The AAGL-Elevating Gynecologic Surgery Special Interest Group for pelvic pain developed a 33-item survey tool to investigate the following topics: (1) current educational experiences with the assessment and management of patients with CPP, (2) satisfaction with fellowship training in CPP, (3) perceived preparedness to treat patients with CPP, (4) plans to incorporate management of CPP into clinical practice, and (5) perceived desires to expand CPP exposure. Composite scores were created to examine experiences related to diseases associated with CPP and pharmaceutical and procedural treatment options. SETTING: Electronic survey. PATIENTS: Not applicable. INTERVENTIONS: The survey was distributed via AAGL email lists and offered on FMIGS social media sites from August 2017 to November 2017 to all active FMIGS fellows and individuals who graduated the fellowship during the preceding 5 years. MEASUREMENTS AND MAIN RESULTS: Fifty-three of 82 (65%) current FMIGS fellows and 104 of 169 (62%) recent fellowship graduates completed the survey. Only 66% of current fellows endorsed working with a fellowship faculty member whose clinical work focused on CPP. Most current fellows reported having a "good amount" of experience or "extensive" experience with superficial endometriosis (39/53, 74%) and deeply infiltrative endometriosis (34/53, 64%), whereas the majority reported having "no" or "little" experience with frequently comorbid conditions like irritable bowel syndrome (68%), pelvic floor tension myalgia (55%), and interstitial cystitis/painful bladder syndrome (51%). For both current fellows and recent graduates, increased CPP Disease Experience composite scores were associated with satisfaction with CPP training (current fellows odds ratio [OR] 1.9, p =.002; recent graduates OR 1.5, p < .001), perceived preparedness to treat patients with CPP (current fellows OR 2.0, p = .0021; recent graduates OR 1.5, p <.001), and the desire to incorporate the treatment of CPP into future clinical practice (current fellows OR 1.8, p = .0099; recent graduates OR 1.3, p = .0178). More than 80% (43/53) of current fellows indicated that they believed an expanded pelvic pain curriculum should be part of the FMIGS fellowship. CONCLUSION: This needs assessment of FMIGS fellows and recent graduates suggests that there are gaps between FMIGS curriculum objectives and current educational experiences, and that fellows desire increased CPP exposure. Expansion and standardization of the CPP educational experience is needed and could lead to increased focus on this disease process among subspecialty benign gynecologic surgeons.

STUDY OBJECTIVE: Compare odds of postoperative urinary symptoms in women who had cystoscopy after benign laparoscopic hysterectomy with 50% dextrose and with normal saline solution with intravenous indigo carmine. DESIGN: Retrospective cohort study. SETTING: Two tertiary care centers. PATIENTS: All women who underwent benign laparoscopic hysterectomy and intraoperative cystoscopy carried out by a single surgeon. INTERVENTIONS: We compared postoperative urinary symptoms in patients who received 50% dextrose cystoscopy fluid (January 2016-June 2017) with those who received saline cystoscopy with intravenous indigo carmine (November 2013-April 2014). MEASUREMENTS AND MAIN RESULTS: A total of 96 patients had cystoscopy with 50% dextrose and 104 with normal saline with intravenous indigo carmine. Differences in baseline characteristics of the two groups of participants mainly reflected institutional population diversity: age (45.2 vs 41.9, pâ¯=â¯.01), body mass index (26.9 vs 33.4, p <.01), race, current smoking status (1% vs 7.8%, pâ¯=â¯.04), diabetes (2.1% vs 11.5%, pâ¯=â¯.01), history of abdominal surgery (53.1% vs 74%, p <.01), hysterectomy type, receipt of intraoperative antibiotics (92.7% vs 100%, p <.01), recatheterization (10.4% vs 0%, p <.01), and removal of catheter on postoperative day 0 (66.7% vs 12.5%, p <.01). Urinary symptoms were similar for 50% dextrose and saline (12.5% vs 7.7%, pâ¯=â¯.19). After adjusting for age, body mass index, race, diabetes, and day of catheter removal, there remained no significant differences in urinary symptoms between the groups (odds ratio 3.19 [95% confidence interval, 0.82-12.35], pâ¯=â¯.09). One immediate bladder injury was detected in the saline group and 1 delayed lower urinary tract injury in the 50% dextrose group. CONCLUSION: Overall, most women experienced no urinary symptoms after benign laparoscopic hysterectomy. There were no significant differences in postoperative urinary symptoms or empiric treatment of urinary tract infection after the use of 50% dextrose cystoscopy fluid as compared with normal saline. The previous finding of increased odds of urinary tract infection after dextrose cystoscopy may be due to use in a high-risk population.

This is the first Enhanced Recovery After Surgery (ERAS) guideline dedicated to standardizing and optimizing perioperative care for women undergoing minimally invasive gynecologic surgery. The guideline was rigorously formulated by an American Association of Gynecologic Laparoscopists Task Force of US and Canadian gynecologic surgeons with special interest and experience in adapting ERAS practices for patients requiring minimally invasive gynecologic surgery. It builds on the 2016 ERAS Society recommendations for perioperative care in gynecologic/oncologic surgery by serving as a more comprehensive reference for minimally invasive endoscopic and vaginal surgery for both benign and malignant gynecologic conditions. For example, the section on preoperative optimization provides more specific recommendations derived from the ambulatory surgery and anesthesia literature for the management of anemia, hyperglycemia, and obstructive sleep apnea. Recommendations pertaining to multimodal analgesia account for the recent Food and Drug Administration warnings about respiratory depression from gabapentinoids. The guideline focuses on workflows important to high-value care in minimally invasive surgery, such as same-day discharge, and tackles controversial issues in minimally invasive surgery, such as thromboprophylaxis. In these ways, the guideline supports the American Association of Gynecologic Laparoscopists and our collective mission to elevate the quality and safety of healthcare for women through excellence in clinical practice.

OBJECTIVE: Our primary objective was to assess the current state of pain and opioid education in obstetrics and gynecology (OBGYN) by performing a detailed review of the national educational curricula guiding OBGYN residency and fellowship training programs in the United States. METHODS: From 2019 to 2020 we reviewed seven documents created to guide learning and structure educational training for OBGYN residency and fellowship programs in the United States: the Council on Resident Education in Obstetrics and Gynecology (CREOG) Educational Objectives Core Curriculum in Obstetrics and Gynecology, the 2016 Educational Objectives-Fellowship in Minimally Invasive Gynecologic Surgery, and the 2018 Guides to Learning in Complex Family Planning, Female Pelvic Medicine & Reconstructive Surgery, Gynecologic Oncology, Maternal Fetal Medicine, and Reproductive Endocrinology and Infertility. Each document was reviewed by two authors to assess for items referring to pain or opioids. RESULTS: The CREOG educational objectives, used to inform educational curricula for residency programs, were the most comprehensive, mentioning pain and/or opioid educational objectives the highest number of times and including the most categories. The CREOG document was followed by the Guides to Learning for Gynecologic Oncology and for Minimally Invasive Gynecologic Surgery. The Reproductive Endocrinology and Infertility Guide to Learning did not mention pain and/or opioids in the educational objectives. CONCLUSIONS: Our study identifies an opportunity for consistent and appropriate opioid and pain management education in OBGYN training.

AIMS: This protocol describes a study aiming to: (1) describe pathways and experiences of women's symptom recognition, appraisal and management of endometriosis; and (2) identify differences in pathways and experiences among a socioeconomically and racially diverse group of women. DESIGN: Descriptive qualitative study with stratified purposeful sampling. METHODS: Data will be collected from a minimum of 24 women with provider-presumed or surgically confirmed diagnoses across two time points. The study will recruit across socioeconomic status (SES) and race/ethnicity (non-Hispanic White, non-Hispanic Black, and Hispanic/Latina) to ensure diversity of the sample. Recruitment will occur at a large public hospital in the southeastern United States (US). Participants will be interviewed using semi-structured interview guides informed by Elder and Giele's Life Course perspective approaching women as active beings in dynamic systems shaped by: 1) their location in time and space; 2) linked lives; and 3) human agency, and 4) the time of their lives. Each woman's experiences, symptoms, and contacts with health-care systems will be mapped to trace their diagnostic pathways. Coded interviews and data will undergo within- and across-case analysis to identify similarities and differences in their experiences. Institutional review board approval was obtained June 2019. DISCUSSION: The participants' diagnostic maps will enable us to distinguish the differences in pathways and experiences between and across groups. Findings will inform the development of interventions aimed at shortening the time to diagnosis. IMPACT: This will be the first study to compare pathways to diagnosis of endometriosis in a socioeconomically and racially diverse sample of US women using the life course perspective. The results from this research stand to inform future interventions aimed at helping women achieve more timely diagnoses.

INTRODUCTION: One-third of non-pregnant women worldwide are anemic.1 Anemia is a known independent risk factor for postoperative morbidity.2 Given that the vast majority of hysterectomies are not performed in the emergency setting, we designed this study to evaluate the effect of preoperative anemia on postoperative morbidity following laparoscopic hysterectomy performed for benign indications. Our main goal is to encourage surgeons to use anemia-corrective measures before surgery when feasible. MATERIAL AND METHODS: Retrospective cohort study of 98 813 patients who underwent a laparoscopic hysterectomy between 2005 and 2016 for benign indications identified through the American College of Surgeons National Surgical Quality Improvement Program. Anemia was examined as a function of hematocrit and was analyzed as an ordinal variable stratified by anemia severity as mild, moderate or severe. Associations between preoperative anemia and patient demographics, preoperative comorbidities and postoperative outcomes were evaluated using univariate analyses. Multivariable logistic regression models were used to identify independent associations between hematocrit level and postoperative outcomes after adjusting for confounding covariates. At the multivariable logistic regression level, anemia severity was analyzed using hematocrit as a continuous variable to assess the independent association between each 5% decrease in hematocrit level and several postoperative morbidities. RESULTS: Of the 98 813 patients who met our inclusion and exclusion criteria, 19.5% were anemic. A lower preoperative hematocrit was associated with higher body mass index, younger age, Black or African American race, longer operative times, and multiple other medical comorbidities. After appropriate regression modeling, anemia was identified as an independent risk factor for extended length of stay, readmission and composite morbidity after surgery. CONCLUSIONS: Preoperative anemia is common among patients undergoing laparoscopic hysterectomy. Preoperative anemia increases patients' risk for multiple postoperative comorbidities. Given that most hysterectomies are performed in the elective setting, gynecologic surgeons should consider the use of anemia-corrective measures to minimize postoperative morbidity.

STUDY OBJECTIVE: To compare intraoperative and 30-day posthysterectomy outcomes between patients who had bariatric surgery before hysterectomy and patients with a body mass index (BMI) >40 kg/m2 without a history of bariatric surgery. DESIGN: A retrospective cohort study. SETTING: A tertiary-care, academic medical center. PATIENTS: Patients with a history of bariatric surgery and patients with BMI >40 kg/m2 and no previous bariatric surgery who underwent any route of hysterectomy between January 1, 2000, and March 1, 2018. INTERVENTIONS: After exclusion of patients with gynecologic malignancy and bariatric surgery reversal, 223 patients with a history of bariatric surgery were matched at a 1:2 ratio by year of hysterectomy to 446 randomly selected patients with a BMI >40 kg/m2 and no bariatric surgery before hysterectomy. Demographics, medical comorbidities, and surgical characteristics were collected by a manual chart review. Chi-square or Fisher's exact tests were used to compare the incidence of intraoperative and 30-day postoperative complications. Polytomous logistic regression was used to estimate the odds of major and minor postoperative complications. Binary logistic regression was used to estimate the odds of any intra- or postoperative complications. MEASUREMENTS AND MAIN RESULTS: The mean BMI in the bariatric surgery group was 35.2 ± 7.9 kg/m2, compared with 46.3 ± 5.6 kg/m2 in the control group (p <.01). Fewer patients in the bariatric surgery group had obesity-related comorbidities than the group with no previous bariatric surgery (p <.01). There were lower odds of any intraoperative complication in the bariatric surgery group than in the group with no bariatric surgery (adjusted odds ratio, 0.32; 95% confidence interval [CI], 0.13-0.77), after adjusting for relevant confounding factors between groups. However, there was no difference in overall postoperative complications between women who had bariatric surgery and those who did not (adjusted odds ratio, 1.25; 95% CI, 0.82-1.91). When analyzed individually, a higher proportion of patients in the bariatric surgery group had postoperative cuff separation or dehiscence (1.4% [3/223], pâ¯=â¯.04) and urinary retention (5.8% [13/223], p <.01). Combining all perioperative complications, we found no significant difference in minor complications, defined as Clavien-Dindo Grade 1 or 2 (adjusted odds ratio, 1.04; 95% CI, 0.68-1.60), major complications, defined as Clavien-Dindo Grade 3 or higher (adjusted odds ratio, 1.25; 95% CI, 0.61-2.54), or combined major and minor perioperative complications (adjusted odds ratio, 0.96; 95% CI, 0.63-1.44) between patients with a history of bariatric surgery and morbidly obese patients with no bariatric surgery before hysterectomy, after adjusting for relevant confounding factors between groups. CONCLUSION: Compared with women who had a BMI >40 kg/m2, patients with a history of bariatric surgery before hysterectomy had a lower odds of complications during hysterectomy. However, despite lower BMI and fewer obesity-related medical comorbidities, there was no significant difference in posthysterectomy complications and no significant differences in overall major and minor complications.

STUDY OBJECTIVE: To examine the impact of perioperative allogeneic blood transfusion (ABT) on postoperative infectious wound occurrences, sepsis-related events. and venous thromboembolism. DESIGN: Retrospective cohort study. SETTING: Hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). PATIENTS: Patients who underwent a minimally invasive hysterectomy for benign indications between 2012 and 2016 were selected from the ACS-NSQIP. Patients with concurrent open hysterectomy, prolapse, or malignancy were excluded. Those with preoperative, intraoperative or postoperative red blood cell transfusion were considered positive for perioperative ABT. INTERVENTION: Minimally invasive hysterectomy for benign indications. MEASUREMENTS AND MAIN RESULTS: Univariate analyses were performed to determine associations of preoperative and intraoperative patient variables and postoperative outcomes with perioperative ABT. Multivariate analysis was completed to test the independent associations of perioperative ABT with outcomes while adjusting for possible confounders. Of the 90,231 patients who met our inclusion criteria, 1447 had a perioperative transfusion (1.6%). Perioperative ABT was associated with multiple preoperative variables. After multivariate analysis, perioperative ABT remained significantly associated with infectious wound events (adjusted odds ratio [aOR], 1.96; 95% confidence interval [CI], 1.9-2.58; p < .001), thromboembolic events (aOR, 2.75; 95% CI, 1.5-5.05; pâ¯=â¯.001), and sepsis events (aOR, 6.49; 95% CI, 4.29-9.79, p < .001). CONCLUSION: ABT is a commonly used to treat perioperative anemia in patients undergoing gynecologic surgery. The results of this study, however, show that perioperative ABT increases a patient's risk of postoperative complications following minimally invasive hysterectomy. Gynecologic surgeons should consider the use of alternative treatments for perioperative anemia, including intravenous iron supplementation, erythropoiesis-stimulating agents, normovolemic hemodilution, and preoperative hormonal suppression, to help reduce the morbidity associated with perioperative ABT.

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.

STUDY OBJECTIVE: To describe the accuracy of historic averages for estimating operating room (OR) time for hysterectomy among women with small and large uteri. DESIGN: A retrospective cohort study. SETTING: Data from women who underwent abdominal, vaginal, or laparoscopic hysterectomy between 2015 and 2017 at the University of North Carolina Hospitals were analyzed. Historic and actual OR times were compared using linear regression. Patient characteristics were also evaluated to determine whether they were associated with the accuracy of predicted OR times. PATIENTS: Nine hundred eighty-five adult women (≥18 years old) who underwent surgery for benign indications or for suspected but not biopsy-confirmed malignancy were included. INTERVENTIONS: Not applicable. MEASUREMENTS AND MAIN RESULTS: Historic averages overestimated OR time by a median of 14 minutes (interquartile range [IQR]â¯=â¯-29 to 49 minutes). The OR time in women with small uteri (<250 g) was significantly more likely to be overestimated than women with large uteri (≥250 g) (median timeâ¯=â¯21 minutes [IQRâ¯=â¯-16 to 52 minutes] and 3 minutes [IQRâ¯=â¯-38 to 44 minutes], respectively; p <. 001). In total laparoscopic hysterectomy and laparoscopy-assisted vaginal hysterectomy, women with uteri ≥250 g took significantly longer than hysterectomy for women with uteri <250 g (36 minutes longer [95% confidence interval, 24-50] and 95 minutes longer [95% confidence interval, 12-179], respectively; p < .001 and pâ¯=â¯.03). CONCLUSION: Using historic averages overestimates OR time, and it is more pronounced in women with small uteri. However, there is a relatively large range of OR times, even among women with the same size uteri. This study highlights the importance of preoperative planning, and in cases in which endometriosis is expected, manually adding time to estimates is recommended.

Chronic pelvic is a multifaceted condition that often has both peripheral and central generators of pain. Despite its high prevalence, the evaluation and management of a pelvic pain patient often present many challenges to the practicing gynecologist. As with many other chronic pain conditions, pain severity does not always correlate with pelvic pathology and standard medical and surgical therapies are not always effective. An understanding of neurobiology and neuropsychology of chronic pelvic pain along with clinical pearls in the history and physical examination should guide management. Successful treatment of pelvic pain is typically multimodal, a combination of pharmacologic treatment strategies directed at the affected pathology and surrounding structures along with behavioral therapy. Evidence for these and other emerging therapies are presented in this article.

The clinical setting in which women's health physicians practice, whether as generalist, obstetricians and gynecologists, or subspecialists, dictates our frequent clinical interaction with "pain." Opioid-containing medications are frequently prescribed within our specialty as a means of immediate pain relief. Opioid-containing medication causes a deep physiological alteration of several systems resulting in potential harm to acute and chronic opioid users. This article includes a thorough system-based review of opioid-containing medications on physiological systems. Women's health providers should have an in-depth understanding of such reverberations on patients' wellbeing to maintain the safest level of care. A solid grasp of physiological repercussions of opioid use would encourage physicians to seek alternative treatment options. Such practice is essential in curbing the opioid epidemic our patients are facing.
