STUDY DESIGN: We conducted a retrospective cohort study to compare wound complications between staples and subcuticular suture closure in women, with a prepregnancy BMI ⩾ 30 kg m − 2 after CD between 2006 and 2011 at an inner-city teaching hospital. Wound complication was defined as a composite of wound disruption (hematoma or seroma) or infection diagnosed up to 6 weeks postpartum. Variables collected include age, parity, prior CDs, prior abdominal surgeries, incision type, chorioamnionitis, maternal comorbidities (hypertension, diabetes) and gestational age. RESULTS: Of the 1147 women included in the study, women with staple closure were older and had higher BMIs (40.6 ± 9.3 versus 36.1 ± 5.4) and were more likely to be multiparous, have a prior CD, diabetes and hypertension compared with women with subcuticular suture. The overall occurrence of wound complications was 15.5% (178/1147). Women with staples had higher wound complications compared with sutures (22.0% versus 9.7%) with a 2.27 unadjusted relative risk (RR) (95% confidence interval (CI), 1.7 to 3.0) and 1.78 adjusted RR (95% CI, 1.27 to 2.49) after controlling for confounders in the final analysis, including vertical skin incisions. CONCLUSIONS: In obese women, skin closure with staples at the time of CD is associated with a higher rate of wound complications compared with subcuticular suture. Skin closure with subcuticular suture over staples should be considered in obese women undergoing a CD regardless of skin incision type.

We profiled transcriptomes of 207,949 individual cells from endometriomata (n=7), extra-ovarian endometriosis (n=19), eutopic endometrium (n=4), unaffected ovary (n=1) and endometriosis-free peritoneum (n=4) to create a cellular atlas of endometrial-type epithelial cells, endometrial-type stromal cells and microenvironmental cell populations across tissue sites. Signatures of endometrial-type epithelium and stroma differed markedly across eutopic endometrium, endometrioma, superficial extra-ovarian disease and deep infiltrating endometriosis, suggesting that extensive transcriptional reprogramming is a core component of the disease process. Endometriomas were notable for the dysregulation of pro-inflammatory pathways and upregulation of complement proteins C3 and C7. Somatic ARID1A mutation in epithelial cells was associated with upregulation of pro-angioge...

DATA SOURCES Literature review of Google Scholar and PubMed. Search terms included a combination of the following: "robotic training", "simulation", "robotic curriculum", "obgyn residency robotic training", "virtual reality robotic training", "DaVinci training", "surgical simulation", "gyn surgical training". Sources considered for inclusion included peer reviewed articles, literature reviews, textbook chapters, and statements from various institutions involved in resident training. METHODS OF STUDY SELECTION A literature search of Google Scholar and PubMed using terms related to robotic surgery and robotics training, as mentioned above. RESULTS Multiple novel platforms that utilize machine learning and real time video feedback to teach and evaluate robotic surgical skills have been developed over recent years. Various training curricula, VR simulators, and other robotic training tools have shown to enhance robotic surgical education and improve surgical skills. Integration of didactic learning, simulation, and intraoperative teaching into more comprehensive training curricula shows positive effects on robotic skills proficiency. Few robotic surgery training curricula have been validated through peer reviewed study, and there is more work to be completed in this area. In addition, there is a lack of information about how skills obtained through robotics curricula and simulation translates into operating room performance and patient outcomes. CONCLUSION Data collected to date shows promising advances in training of robotic surgeons. A diverse array of curricula for training robotic surgeons continues to emerge, and existing teaching modalities are evolving to keep up with the rapid demand for proficient robotic surgeons. Futures areas of growth include establishing competency benchmarks for existing training tools, validating existing curricula, and determining how to translate acquired skills in simulation to performance in the operating room and patient outcomes. Many surgical training platforms are beginning to expand beyond discreet robotic skills training to procedure-specific and team training. There is still a wealth of research to be done to understand how to create an effective training experience for gyn surgical trainees and robotics teams.

Secondary objectives were assessment of surgeons' visualization of the operative field, anesthesiologists' ability to maintain adequate end-tidal CO 2 (etCO 2), and patients' report of postoperative shoulder pain. Design: A randomized controlled trial using an equal allocation ratio into 4 arms: standard insufflation/IAP 10 mm Hg, standard insufflation/IAP 15 mm Hg, valveless insufflation/IAP 10 mm Hg, and valveless insufflation/IAP 15 mm Hg. Setting: Single tertiary care academic institution. Patients: Women ≥ 18 years old undergoing nonemergent conventional or robotic gynecologic laparoscopic surgery. Interventions: A standard or valveless insufflation system at IAPs of 10 or 15 mm Hg. Measurements and Main Results: One hundred thirty-two patients were enrolled and randomized with 33 patients per group. There were 84 robotic cases and 47 conventional laparoscopic cases. CO 2 absorption rates (mL/kg*min) did not differ across groups with mean rates of 4.00 § 1.3 in the valveless insufflation groups and 4.00 § 1.1 in the standard insufflation groups. The surgeons' rating of overall visualization of the operative field on a 10-point Likert scale favored the valveless insufflation system (median visualization, 9.0 § 2.0 cm and 9.5 § 1.8 cm at 10 and 15 mm Hg, respectively) over standard insufflation (7.0 § 3.0 cm and 7.0 § 2.0 cm at 10 and 15 mm Hg, respectively; p <.001). The anesthesiologists' ability to maintain adequate etCO 2 was similar across groups (p = .417). Postoperative shoulder pain scores were low overall with no significant difference across groups (p >.05). Conclusion: CO 2 absorption rates, anesthesiologists' ability to maintain adequate etCO 2 , and postoperative shoulder pain did not differ based on insufflation system type or IAP. Surgeons' rating of visualization of the operative field was significantly improved when using the valveless over the standard insufflation system.

During counseling, 91% of surgeons addressed patient goals; only 54% documented them. 83% used printed education materials during consent, but only 7% formally assessed literacy; 84% judged literacy by conversation. In order of importance, surgical risks and complications were rated highest (71.97 on a scale of 0-100), followed by alternative treatments (71.2), alternative surgical routes (56.7), and postoperative expectations (44.8). Following risks of bleeding, infection, and injury to nearby organs, the next most-counseled areas were urinary tract injury (93%), conversion between routes / bowel injury (91% each), blood transfusion (88%), and early surgical menopause (84%). 33% of surgeons provided a copy of the consent, 38% only if requested. Most attendings did not observe trainees if consent was delegated (57%). Conclusions: The majority of surgeons learn informed consent through observation. Lack of training requires the resident or fellow to volunteer discomfort and ask for guidance, risking embarrassment. Surgeons can improve in assessing literacy, documenting goals, and observing trainees. The results of this survey will help create an evaluation tool for teaching informed consent, with standards established by expert surgeons.

In 2015, approximately 650 000 robot-assisted procedures were performed worldwide. Surgeons must be properly trained to safely transition to using such innovative technology. Multiple virtual reality robotic simulators are now commercially available for educational and training purposes. There is a need for comparative evaluations of these simulators to aid users in selecting an appropriate device for their purposes. We conducted a comparison of the design and capabilities of all dedicated simulators of the da Vinci robot - the da Vinci Skills Simulator (dVSS), dV-Trainer (dVT), Robotic Skills Simulators (RoSS) and the RobotiX Mentor. This paper provides the base specifications of the hardware and software, with an emphasis on the training capabilities of each system. Each simulator contains a larg...

These data indicate identical costs of care for MIS and open surgery, but a 3.5 times greater risk of complications with open surgery. We anticipate that the rate of MIS and corresponding quality of care will improve with recent adoption of Commission on Cancer measures.

To evaluate the impact of learning preference on performance. METHODS: Prospective study in academic medical center. OBGYN residents and medical students on gynecology were assigned to traditional (TT) or video-based (VBT) training for total laparoscopic hysterectomy skills. TT included routine didactic and clinical instruction. VBT additionally included two types of videos: 1) cognitive, 2) psychomotor skills-based. Participants received pre- and post-intervention knowledge and skills assessments. The VARK© questionnaire determined learning preference. Change in assessment scores was compared. The relationship between learning preference, intervention group, and change in assessment scores was analyzed. RESULTS: 120 students (n=59 VBT v. n=61 TT) and 24 residents (n=12 per group) participated. Mean improvement...

To our knowledge, there are limited studies evaluating the effect of BMI on accuracy of bimanual examination and a more recent investigation is long overdue. METHODS: This was a retrospective chart review of patients over the age of 18 undergoing hysterectomy for benign indications between July 2010 and July 2015. Bimanual examination and ultrasound measurements of the uterus prior to surgery were compared to pathology weight and then their accuracy was compared based on BMI. Concordance correlation coefficients were used to estimate accuracy of these measurements. Bland-Altman plots were used to compare the weights from clinical exam and ultrasound to the actual pathology weight. RESULTS: 981 records were reviewed, of those 364 met inclusion criteria. Average weight of the uterus was 454.04 gm (+/-475.27). Average age an...

RESULTS: Among 70 patients offered enrollment in this study, 67 (96%) consented, and complete data are available for 62 (93%). Mean age was 51.1 years (AE 9.4). Median body mass index (BMI) was 27.1 kg/m2; median vaginal parity was 2 (0-4), and 43% were postmenopausal. The primary indication for hysterectomy was prolapse (76%), heavy menstrual bleeding (18%), and other (6%). Vaginal salpingectomy was successfully performed in 46/62 (74%) women. Mean operating time for bilateral salpingectomy was 11 minutes (AE 5.7), with additional mean EBL of 6 cc (AE 17.3). There were 8 surgical complications: 3 hemorrhages > 500 ml and 5 conversions to alternate routes of surgery, but none of these were due to the salpingectomy. Mean uterine weight was 68 grams and there were no abnormalities on fallopian tube pathology. Among the 16 patients in whom planned bilateral salpingectomy was not completed, unilateral salpingectomy was performed in 6 and both tubes were left in situ in 10. Reasons for non-completion of salpingectomy included: tubes were too high in the pelvis (7), conversion to alternate route for pathology (2), ovarian adhesions (2), bowel or sidewall adhesions (3), no reason (1), and ovarian pathology requiring oophorectomy (1). There were no identified risk factors for unsuccessful salpingectomy including age (p ¼ 0.05), BMI (p ¼ 0.68), and prior tubal ligation (p ¼ 0.052). Mean MRS scores did not significantly change from preoperatively to postoperatively (9.85 vs 6.04, p ¼ 0.61). CONCLUSION: Vaginal salpingectomy is feasible in the majority of women undergoing planned vaginal hysterectomy and increases operating time by 11 minutes and EBL by 6 cc. Risk factors for unsuccessful removal could not be identified.

Abstract Study Objective: To compare the incidence of unsuspected uterine sarcoma based on surgical approach: open versus minimally invasive approaches for myomectomies and hysterectomies. Design: Retrospective chart review of demographic data, preoperative characteristics, operative details, and pathology results from the electronic medical record. Design Classification: II-3 Setting: A large, urban, academic medical center. Patients: All women undergoing myomectomy or hysterectomy performed for benign indications by a benign gynecologic surgery between 2010 and 2014. Measurements and Main Results: A total of 1,959 myomectomies and hysterectomies were performed; four unsuspected uterine sarcomas were identified for an incidence of 2.0 per cases. The sarcoma incidence during open abdominal surgery (3 in 743 cases, or .40%) was similar to the incidence during minimally invasive surgery (1 in 1216 cases, or .08%) (p=.16). The mean age, body mass index, and specimen weights were also similar. Though over a quarter of all cases were morcellated, with the majority performed via power morcellation, no specimens with sarcoma were morcellated. Conclusion: The incidence of unsuspected uterine sarcoma during myomectomy or hysterectomy for benign indications is low at our institution, and is similar for open versus minimally invasive cases. Patients should be counseled on the risks and benefits of both minimally invasive and open surgical approaches. Introduction The benefits of minimally invasive surgery (MIS) in gynecology have been well established with level I evidence. Some of these benefits include fewer perioperative complications such as lower estimated blood loss, fewer wound infections, and less postoperative fever, as well as shorter hospital stays and faster return to normal activities following surgery [1-4]. Conversely, MIS has also been associated with a higher incidence of urinary tract injuries and longer operative time compared to open gynecologic surgery [1,2]. Minimally invasive approaches to hysterectomy and myomectomy often require morcellation of tissue to facilitate removal through small incisions. The U.S. Food and Drug Administration (FDA) released a Safety Communication in April 2014, which discouraged power morcellation during fibroid surgery in perimenopausal or menopausal women due to the risk of disseminating unsuspected uterine sarcoma [5,6]. The concern with inadvertent dissemination of occult malignancy is the potential to worsen prognosis [7,8]. The FDA's estimated incidence of unsuspected sarcoma at the time of surgery for presumed fibroids was 2.8 per 1000 cases [5,6]. Many other studies attempting to estimate the risk of unsuspected uterine sarcoma have been conducted, with wide variations from 0 to 6 per 1000 operations [9-27]. Following the FDA's Safety Communication, there was noted to be an increase in laparotomy rates for hysterectomy and myomectomy with a decrease in minimally invasive approaches for these procedures [28-32]. Evidence is mixed regarding whether this trend in surgical approach has led to increased morbidity from gynecologic surgery. Some studies have found that the rates of hospital readmission and estimated blood loss
