Validation of a Simulation Model for Robotic Myomectomy.

STUDY OBJECTIVE: Several simulation models have been evaluated for gynecologic procedures such as hysterectomy, but there are limited published data for myomectomy. This study aimed to assess the validity of a low-cost robotic myomectomy model for surgical simulation training. DESIGN: Prospective cohort simulation study. SETTING: Surgical simulation laboratory. PARTICIPANTS: Twelve obstetrics and gynecology residents and 4 fellowship-trained minimally invasive gynecologic surgeons were recruited for a 3:1 novice-to-expert ratio. INTERVENTIONS: A robotic myomectomy simulation model was constructed using <$5 worth of materials: a foam cylinder, felt, a stress ball, bandage wrap, and multipurpose sealing wrap. Participants performed a simulation task involving 2 steps: fibroid enucleation and hysterotomy repair. Video-recorded performances were timed and scored by 2 blinded reviewers using the validated Global Evaluative Assessment of Robotic Skills (GEARS) scale (5-25 points) and a modified GEARS scale (5-40 points), which adds 3 novel domains specific to robotic myomectomy. Performance was also scored using predefined task errors. Participants completed a post-task questionnaire assessing the model's realism and utility. MEASUREMENTS AND MAIN RESULTS: Median task completion time was shorter for experts than novices (9.7 vs 24.6 min, p = .001). Experts scored higher than novices on both the GEARS scale (median 23 vs 12, p = .004) and modified GEARS scale (36 vs 20, p = .004). Experts made fewer task errors than novices (median 15.5 vs 37.5, p = .034). For interrater reliability of scoring, the intraclass correlation coefficient was calculated to be 0.91 for the GEARS assessment, 0.93 for the modified GEARS assessment, and 0.60 for task errors. Using the contrasting groups method, the passing mark for the simulation task was set to a minimum modified GEARS score of 28 and a maximum of 28 errors. Most participants agreed that the model was realistic (62.5%) and useful for training (93.8%). CONCLUSION: We have demonstrated evidence supporting the validity of a low-cost robotic myomectomy model. This simulation model and the performance assessments developed in this study provide further educational tools for robotic myomectomy training.

What are essential laparoscopic skills these days? Results of the SAGES Fundamentals of Laparoscopic Surgery (FLS) Committee technical skills survey.

INTRODUCTION: The Fundamentals of Laparoscopic Surgery (FLS) program tests basic knowledge and skills required to perform laparoscopic surgery. Educational experiences in laparoscopic training and development of associated competencies have evolved since FLS inception, making it important to review the definition of fundamental laparoscopic skills. The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) assigned an FLS Technical Skills Working Group to characterize technical skills used in basic laparoscopic surgery in current practice contexts and their possible application to future FLS tests. METHODS: A group of subject matter experts defined an inventory of 65 laparoscopic skills using a Nominal Group Technique. From these, a survey was developed rating these items for importance, frequency of use, and priority for testing for FLS certification. This survey was distributed to SAGES members, recent recipients of FLS certification, and members of the Association of Program Directors in Surgery (APDS). Results were collected using a secure web-based survey platform. RESULTS: Complete data were available for 1742 surveys. Of these, 1143 comprised results for post-residency participants who performed advanced procedures. Seventeen competencies were identified for FLS testing prioritization by determining the proportion of respondents who identified them of highest priority, at median (50th percentile) of the maximum survey scale rating. These included basic peritoneal access, laparoscope and instrument use, tissue manipulation, and specific problem management skills. Sixteen could be used to show appropriateness of the domain construct by confirmatory factor analysis. Of these 8 could be characterized as manipulative tasks. Of these 5 mapped to current FLS tasks. CONCLUSIONS: This survey-identified competencies, some of which are currently assessed in FLS, with a high level of priority for testing. Further work is needed to determine if this should prompt consideration of changes or additions to the FLS technical skills test component.

Interactive video module and simulated model for uterine manipulation during laparoscopic hysterectomy.

BACKGROUND: Hysterectomy is one of the most common gynecologic surgeries, with an increasing proportion of hysterectomies performed by a laparoscopic approach. Uterine manipulation is critical for patient safety and surgical efficiency; however, the most junior member of the surgical team assumes the responsibility of uterine manipulation, commonly without preparation. The objective of our study was to determine whether kinesthetic learning using a low-cost simulated pelvic model while learning the uterine manipulation maneuvers of a laparoscopic hysterectomy improves learning efficacy and application efficiency compared to an interactive video module alone. METHODS: Our randomized control trial at an academic medical center included forty first-year and second-year medical students. Participants were randomized to the intervention group that used a low-cost simulated pelvic model for kinesthetic learning during the video module or the control group who only had the interactive video module to learn the uterine manipulation maneuvers of a laparoscopic hysterectomy. RESULTS: Participants in the intervention group were less likely to make unnecessary movements with demonstration of both pelvic side walls (right wall: control 78.9%, intervention 42.9%, p < 0.027; left wall: control 94.7%, intervention 66.7%, p < 0.046), and this was more pronounced in novice first-year participants (p < 0.009). Additionally, participants in the intervention group reported higher perceived preparedness (100% versus 71.4% in control group, p < 0.037). However, there was no difference in verbal or physical cues required, time per task, or force used between the groups. CONCLUSION: Kinesthetic practice may not be required for learning the uterine manipulation maneuvers of a laparoscopic hysterectomy, but it may be beneficial for more novice learners and to increase learners' perceived preparedness. Our novel interactive video module alone may be sufficient to prepare learners to perform uterine manipulation maneuvers prior to the operating room.

A systematic review on the use of artificial intelligence in gynecologic imaging - Background, state of the art, and future directions.

OBJECTIVE: Machine learning, deep learning, and artificial intelligence (AI) are terms that have made their way into nearly all areas of medicine. In the case of medical imaging, these methods have become the state of the art in nearly all areas from image reconstruction to image processing and automated analysis. In contrast to other areas, such as brain and breast imaging, the impacts of AI have not been as strongly felt in gynecologic imaging. In this review article, we: (i) provide a background of clinically relevant AI concepts, (ii) describe methods and approaches in computer vision, and (iii) highlight prior work related to image classification tasks utilizing AI approaches in gynecologic imaging. DATA SOURCES: A comprehensive search of several databases from each database's inception to March 18th, 2021, English language, was conducted. The databases included Ovid MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, and Daily, Ovid EMBASE, Ovid Cochrane Central Register of Controlled Trials, and Ovid Cochrane Database of Systematic Reviews and ClinicalTrials.gov. METHODS OF STUDY SELECTION: We performed an extensive literature review with 61 articles curated by three reviewers and subsequent sorting by specialists using specific inclusion and exclusion criteria. TABULATION, INTEGRATION, AND RESULTS: We summarize the literature grouped by each of the three most common gynecologic malignancies: endometrial, cervical, and ovarian. For each, a brief introduction encapsulating the AI methods, imaging modalities, and clinical parameters in the selected articles is presented. We conclude with a discussion of current developments, trends and limitations, and suggest directions for future study. CONCLUSION: This review article should prove useful for collaborative teams performing research studies targeted at the incorporation of radiological imaging and AI methods into gynecological clinical practice.

Endometriosis biomarkers of the disease: an update.

PURPOSE OF REVIEW: Endometriosis is a complex benign gynaecologic condition with heterogenous presentations and a large impact on the global healthcare system and on the quality of life for millions of women. Currently, the gold standard for diagnosis involves direct visualization of lesions during surgery confirmed by histopathological diagnosis, resulting in an average delay in its initial diagnosis of 8-10 years. Therefore, the search for noninvasive diagnostic testing options has been subject to a large body of research. RECENT FINDINGS: Multiple potential biomarkers have been explored for noninvasive testing for endometriosis, including glycoproteins, inflammatory cytokines, immunological molecules, angiogenesis markers, hormones, micro RNAs (miRNAs), proteomics, metabolomics, genomics and the microbiome. SUMMARY: Although there are challenges to consider, areas for real promise and advancement in the noninvasive diagnosis of endometriosis are currently being explored with real promise in the area of miRNAs, proteomics, metabolomics, genomics and the microbiome.

Development and validation of a simulation model for laparoscopic myomectomy.

BACKGROUND: Simulation is an important adjunct to traditional surgical training, allowing for repetitive practice of new skills without compromising patient safety. Although several simulation models have been described and evaluated for gynecologic procedures, there is a lack of such models for laparoscopic myomectomy. OBJECTIVE: This study aimed to design a low-cost, low-fidelity laparoscopic myomectomy simulation model and to assess the model's validity as a training tool. STUDY DESIGN: The model was constructed using a "cup turner" foam cylinder, felt, a 2-inch stress ball, self-adhesive bandage wrap, multipurpose sealing wrap, red marker, and hook-and-loop fastener. Participants were recruited at a quaternary care academic center and at the Society for Gynecologic Surgeons Annual Scientific Meeting. The simulation task involved the following 2 steps: fibroid enucleation and hysterotomy repair. Validity evidence was collected by comparing expert and novice simulation task performances. Video recordings were scored by 2 blinded reviewers using the Global Operative Assessment of Laparoscopic Skills scale (5-20 points) and a modified Global Operative Assessment of Laparoscopic Skills scale (5-35 points), incorporating 3 novel domains specific to laparoscopic myomectomy. The Mann-Whitney U test was used to compare the task completion times and performance scores. Interrater reliability of scoring was assessed using the interclass correlation coefficient. Validity was also assessed with a post-task survey regarding the model's realism, utility, and educational effect. RESULTS: The total cost to construct each model was under $5. A 3:1 ratio was used to recruit 15 novices and 5 experts. The median time to task completion was shorter for experts than for novices (11.8 vs 20.1 minutes; P=.004). The experts scored higher than the novices on both the Global Operative Assessment of Laparoscopic Skills scale (median 19 [range 13-20] vs 10 [6-17.5]; P=.007) and the modified Global Operative Assessment of Laparoscopic Skills scale (31.5 [21.5-33.5] vs 18.5 [13.5-32]; P=.009). The interclass correlation coefficient was 0.95 for the Global Operative Assessment of Laparoscopic Skills scores and 0.96 for the modified Global Operative Assessment of Laparoscopic Skills scores. Most of the participants agreed that the model closely approximated the feel of fibroid enucleation (70% [14/20]) and suturing the uterus (80% [16/20]). All the participants agreed that the model was useful for learning or teaching laparoscopic myomectomy. CONCLUSION: This study demonstrates evidence supporting the validity of a novel, low-cost laparoscopic myomectomy model and a novel assessment scale for laparoscopic myomectomy training. This simulation model provides a targeted training tool that allows learners to focus on the key aspects of laparoscopic myomectomy and may improve readiness for the operating room.

Surgical Science-Simbionix Robotic Hysterectomy Simulator: Validating a New Tool.

STUDY OBJECTIVE: To gather validity evidence for and determine acceptability of Surgical Science-Simbionix Hysterectomy Modules for the DaVinci Xi console simulation system (software; 3D Systems by Simbionix [now Surgical Science-Simbionix], Littleton, CO, and hardware; Intuitive Surgical, Inc., Sunnyvale, CA) and evaluate performance benchmarks between novice and experienced or expert surgeons. DESIGN: Prospective education study (Messick validity framework). SETTING: Multicenter, academic medical institutions. PARTICIPANTS: Residents, fellows, and faculty in obstetrics and gynecology were invited to participate at 3 institutions. Participants were categorized by experience level: fewer than 10 hysterectomies (novice), 10 to 50 hysterectomies (experienced), and more than 50 hysterectomies (expert). A total of 10 novice, 10 experienced, and 14 expert surgeons were included. INTERVENTIONS: Participants completed 4 simulator modules (ureter identification, bladder flap development, colpotomy, complete hysterectomy) and a qualitative survey. Simulator recordings were reviewed in duplicate by educators in minimally invasive gynecologic surgery using the Modified Global Evaluative Assessment of Robotic Skills (GEARS) rating scale. MEASUREMENTS AND MAIN RESULTS: Most participants felt that the simulator realistically simulated robotic hysterectomy (64.7%) and that feedback provided by the simulator was as or more helpful than feedback from previous simulators (88.2%) but less helpful than feedback provided in the operating room (73.5%). Participants felt that this simulator would be helpful for teaching junior residents. Simulator-generated metrics correlated with GEARS performance for the bladder flap and ureter identification modules in multiple domains including total movements and total time for completion. GEARS performance for the bladder flap module correlated with experience level (novice vs experienced/expert) in the domains of interest and total score but did not consistently correlate for the other procedural modules. Performance benchmarks were evaluated for the bladder flap module for each GEARS domain and total score. CONCLUSION: The modules were well received by participants of all experience levels. Individual simulation modules appear to better discriminate between novice and experienced/expert users than overall simulator performance. Based on these data and participant feedback, the use of individual modules in early residency education may be helpful for providing feedback and may ultimately serve as 1 component of determining readiness to perform robotic hysterectomy.

Robotic Surgery: The Impact of Simulation and Other Innovative Platforms on Performance and Training.

OBJECTIVE: To review the current status of robotic training and the impact of various training platforms on the performance of robotic surgical trainees. DATA SOURCES: Literature review of Google Scholar and PubMed. The 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." The 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 in the "Data Sources" section. RESULTS: Multiple novel platforms that use machine learning and real-time video feedback to teach and evaluate robotic surgical skills have been developed over recent years. Various training curricula, virtual reality simulators, and other robotic training tools have been shown to enhance robotic surgical education and improve surgical skills. The 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 the skills obtained through robotics curricula and simulation translate into operating room performance and patient outcomes. CONCLUSION: Data collected to date show promising advances in the training of robotic surgeons. A diverse array of curricula for training robotic surgeons continue to emerge, and existing teaching modalities are evolving to keep up with the rapidly growing 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 the acquired skills in simulation into performance in the operating room and patient outcomes. Many surgical training platforms are beginning to expand beyond discrete 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 gynecologic surgical trainees and robotics teams.

Improving patient access through office hysteroscopy clinic redesign.

BACKGROUND AND OBJECTIVE: Patients with abnormal uterine bleeding (AUB) often require hysteroscopy as part of the diagnostic workup. The purpose of this study was to improve efficiency by shortening the time to patient appointment for office hysteroscopy. INTERVENTIONS: Preintervention, nurse practitioners (NPs) and gynecologists saw patients with abnormal uterine bleeding (AUB) separately. This created inefficiency for the patients, frequently requiring second visits for hysteroscopy. A new hysteroscopy clinic was designed to increase practice efficiency. A collaborative team model was created including consecutive visits with NPs and gynecologists. Each patient with AUB was first evaluated by an NP, followed immediately by a shorter visit with a gynecologist for office hysteroscopy as indicated. NPs managed other diagnostic evaluation and bleeding treatment if hysteroscopy was not warranted. Collaborative clinic staffing consisted of two NPs seeing patients with AUB paired with one gynecologist for procedural support. MEASUREMENTS AND RESULTS: Electronic records of 393 patients scheduled for AUB visits from January to June 2015 were evaluated for preintervention data. Postintervention, 647 patient records were reviewed from January to June of 2016. During the preintervention period, 30% of patients had a hysteroscopy appointment scheduled within 0-13 days from the initial visit for AUB. Postintervention, the wait time for appointments decreased, with 63% of patients scheduled within 0-13 days. Clinic redesign also resulted in an increase of 57.5% in appointment slots. No-show rates and appointment fill rates were not adversely affected. CONCLUSIONS: A collaborative team-based care model using NPs and gynecologists improved efficiency and access to office hysteroscopy services.

Teaching learners to raise the roof: a vaginal surgery simulator for apical suspension.

INTRODUCTION AND HYPOTHESIS: The objective was to discuss the importance of apical suspension following vaginal hysterectomy and demonstrate a surgical model to aide in educating learners on a variety of apical suspension procedures. METHODS: Rates of pelvic organ prolapse are not insignificant following hysterectomy. Re-support of the vaginal apex should be performed at the time of hysterectomy in those with or without a diagnosis of prolapse. Exposure to vaginal apical support procedures may be limited owing to declining rates of vaginal hysterectomy and limited trainee work hours. Surgical models are increasingly being used to supplement operating room experience. The model we present was originally developed for hysterectomy, although its design allows for teaching a variety of apical support procedures that incorporate the uterosacral ligament (USL) for support. We demonstrate performing a USL suspension, internal McCall suture, and modified McCall suture using the model. RESULTS: The model is constructed from readily available supplies, is multi-use, and inexpensive. It allows learners to identify relevant anatomy, understand/visualize surgical steps, and practice suturing technique. CONCLUSION: Pelvic organ prolapse is common in women, although opportunities to teach apical suspension procedures may be limited. The proposed vaginal surgery simulator can be used to supplement the experience of gynecological surgery trainees with apical suspension procedures.

Career Interest and Psychomotor Aptitude Among Medical Students.

OBJECTIVE: The primary objective is to assess psychomotor aptitude of medical students interested in pursuing a procedural career. Secondary objectives include exploring the relationship between actual and perceived aptitude, and identifying predictors of superior aptitude. DESIGN: This is a cross-sectional, multisite study in which participants completed a paper survey, four visuospatial aptitude assessments, and a laparoscopic simulation modeled after the Fundamentals of Laparoscopic Surgery (FLS) peg transfer test (used as a proxy for psychomotor aptitude). SETTING: Johns Hopkins University School of Medicine and Mayo Clinic School of Medicine. PARTICIPANTS: All second-year medical students who had not yet initiated clinical rotations were eligible. Sixty-four students participated. RESULTS: Students interested in a procedural career exhibited superior psychomotor aptitude (faster FLS task completion time), and a majority of these students correctly identified themselves as having above-average aptitude compared with peers. However, over one quarter of all students, regardless of career interest, incorrectly over- or under-rated their psychomotor aptitude. Upon completing their preclinical curriculum, a minority of students felt prepared to participate or assist in their surgical clinical rotations. CONCLUSIONS: Prior to embarking on their clinical rotations, over one quarter of medical students lack awareness of their psychomotor aptitude and many do not feel prepared to participate in the next phase of their training. Early aptitude testing and introduction to laparoscopic training may assist in career selection, preparedness, and success.

Visuospatial Aptitude Testing Differentially Predicts Simulated Surgical Skill.

OBJECTIVE: To determine whether visuospatial perception (VSP) testing is correlated to simulated or intraoperative surgical performance as rated by the American College of Graduate Medical Education (ACGME) milestones. DESIGN: (Canadian Task Force classification II-2). SETTING: Two academic training institutions. PARTICIPANTS: Forty-one residents, including 19 from Brigham and Women's Hospital and 22 from the Mayo Clinic, from 3 different specialties: obstetrics and gynecology, general surgery, and urology. INTERVENTION: Participants underwent 3 different tests: visuospatial perception testing (VSP), Fundamentals of Laparoscopic Surgery (FLS) peg transfer, and da Vinci robotic simulation peg transfer. Surgical grading from the ACGME milestones tool was obtained for each participant. Demographic and background information was also collected, including specialty, year of training, previous experience with simulated skills, and surgical interest. Standard statistical analyses were performed using Student's t test, and correlations were determined using adjusted linear regression models. MEASUREMENTS AND MAIN RESULTS: In univariate analysis, Brigham and Women's Hospital and Mayo Clinic training programs differed in times and overall scores for both the FLS peg transfer and da Vinci robotic simulation peg transfer tests (p < .05 for all). In addition, type of residency training affected time and overall score on the robotic peg transfer test. Familiarity with tasks correlated with higher score and faster task completion (p = .05 for all except VSP score). There were no differences in VSP scores by program, specialty, or year of training. In adjusted linear regression modeling, VSP testing was correlated only to robotic peg transfer skills (average time, p = .006; overall score, p = .001). Milestones did not correlate to either VSP or surgical simulation testing. CONCLUSION: VSP score was correlated with robotic simulation skills, but not with FLS skills or ACGME milestones. This suggests that the ability of VSP score to predict competence differs between tasks. Therefore, further investigation of aptitude testing is needed, especially before its integration as an entry examination into a surgical subspecialty.

Changes over time in the health and functioning of older people moving into care homes: analysis of data from the English Longitudinal Study of Ageing.

Background: the number of people requiring care home support is projected to rise in future years, but little information is available on the needs of new care home residents. Objective: to measure the health and functioning of people moving into care homes and how they have changed between 2002 and 2015. Setting: English Longitudinal Study of Ageing. Participants: two hundred fifty-four of the 313 (1.99%) individuals who moved from the community into a care home, and were interviewed in the survey wave prior to entry. Main outcome measures: changes over time for number of health conditions and functional deficits (deficits in activities of daily living (ADL), and instrumental ADLs (IADLs)), assessed in the survey wave prior to admission. Results: over time there were significant increases in the total number of health conditions and functional deficits amongst soon to be care home entrants (P = 0.0011), the proportion with high blood pressure (OR 1.37, 95% CI: 1.17-1.62, P < 0.0001), memory problems (OR 1.33, 95% CI: 1.11-1.61, P = 0.0021) or total number of IADL deficits (P = 0.008). Non-significant increases were observed in the proportion of care home entrants with cancer (OR 1.23, 95% CI: 0.93-1.65, P = 0.15), lung disease (OR 1.21, 95% CI: 0.85-1.75), heart disease (OR 1.12, 95% CI: 0.95-1.30) and arthritis (OR 1.11, 95% CI: 0.95-1.30). Stroke and ADL deficits did not increase. No differential ageing effect was observed. Conclusions: the support needs of care home entrants in England appear to be increasing over time. This has important implications for the provision and funding of care home places and community services.

Hysteroscopic Morcellation Versus Resection for the Treatment of Uterine Cavitary Lesions: A Systematic Review and Meta-analysis.

This systematic review and meta-analysis compares hysteroscopic morcellation with electrosurgical resection to treat uterine cavitary lesions. A search of Ovid MEDLINE, Ovid Embase, Scopus, and Web of Science was conducted through August 18, 2015, for randomized controlled trials (RCTs) and prospective and retrospective studies, regardless of surgical indication and study language or sample size. Seven studies were eventually included (4 RCTs and 3 retrospective observational studies), enrolling 650 women. The meta-analysis showed that the total procedure time was significantly shorter for morcellation than for resection (weighted mean difference = 9.36 minutes; 95% confidence interval [CI], -15.08 to -3.64). When reviewing RCTs only, intrauterine morcellation was associated with a smaller fluid deficit and lower odds of incomplete lesion removal. This difference was not statistically significant in observational studies. There was no significant difference in the odds of surgical complications (odds ratio = 0.72; 95% CI, 0.20-2.57) or the number of insertions (weighted mean difference = -3.04; 95% CI, -7.86-1.78). In conclusion, compared with hysteroscopic resection, hysteroscopic morcellation is associated with a shorter operative time and possibly lower odds of incomplete lesion removal. The certainty in evidence was limited by heterogeneity and the small sample size.

Establishing Benchmarks For Minimum Competence With Dry Lab Robotic Surgery Drills.

The Robotic Objective Structured Assessment of Technical Skills (R-OSATS) is a previously validated assessment tool that is used to assess 5 standardized inanimate robotic surgery drills. R-OSATS is used to evaluate performance on surgical drills, with scores of 0 to 20 for each drill. Our objective was to establish the minimum threshold score that denotes competence on these drills. Thus, we performed a standard setting study using data from surgeons and trainees in 8 academic medical centers. Cutoff scores for the minimal level of competence using R-OSATS were established using 2 techniques: the modified Angoff and the contrasting groups methods. For the modified Angoff method, 8 content experts met and, in an iterative process, derived the scores that a minimally competent trainee should receive. After 2 iterative rounds of scoring and discussion with the modified Angoff method, we established a minimum competence score per drill with high agreement (rWG range, 0.92-0.98). There was unanimous consensus that a trainee needs to achieve competence on each independent drill. A second method, the contrasting groups method, was used to verify our results. In this method, we compared R-OSATS scores from "inexperienced" (34 postgraduate year 1 and 2 trainees) with "experienced" (22 faculty and fellow) robotic surgeons. The distributions of scores from both groups were plotted, and a cutoff score for each drill was determined from the intersection of the 2 curves. Using this method, the minimum score for competence would be 14 per drill, which is slightly more stringent but confirms the results obtained from the modified Angoff approach. In conclusion, using 2 well-described standard setting techniques, we have established minimum benchmarks designating trainee competence for 5 dry lab robotic surgery drills.

Incorporating resident/fellow training into a robotic surgery program.

With the rapid uptake of the robotic approach in gynecologic surgery, a thorough understanding of the technology, including its uses and limitations, is critical to maximize patient outcomes and safety. This review discusses the role of training modalities and development of curricula for robotic surgery. Furthermore, methods for incorporating the entire surgical team and the process of credentialing/maintaining privileges are described.

Validity and reliability of the robotic Objective Structured Assessment of Technical Skills.

OBJECTIVE: Objective Structured Assessments of Technical Skills have been developed to measure the skill of surgical trainees. Our aim was to develop an Objective Structured Assessments of Technical Skills specifically for trainees learning robotic surgery. METHODS: This is a multiinstitutional study conducted in eight academic training programs. We created an assessment form to evaluate robotic surgical skill through five inanimate exercises. Gynecology, general surgery, and urology residents, Fellows, and faculty completed five robotic exercises on a standard training model. Study sessions were recorded and randomly assigned to three blinded judges who scored performance using the assessment form. Construct validity was evaluated by comparing scores between participants with different levels of surgical experience; interrater and intrarater reliability were also assessed. RESULTS: We evaluated 83 residents, nine Fellows, and 13 faculty totaling 105 participants; 88 (84%) were from gynecology. Our assessment form demonstrated construct validity with faculty and Fellows performing significantly better than residents (mean scores 89±8 faculty, 74±17 Fellows, 59±22 residents; P<.01). In addition, participants with more robotic console experience scored significantly higher than those with fewer prior console surgeries (P<.01). Robotic Objective Structured Assessments of Technical Skills demonstrated good interrater reliability across all five drills (mean Cronbach's α 0.79±0.02). Intrarater reliability was also high (mean Spearman's correlation 0.91±0.11). CONCLUSION: We developed a valid and reliable assessment form for robotic surgical skill. When paired with standardized robotic skill drills, this form may be useful to distinguish between levels of trainee performance. LEVEL OF EVIDENCE: II.

Virtual reality robotic surgical simulation: an analysis of gynecology trainees.

STUDY OBJECTIVE: To analyze the learning curves of gynecology trainees on several virtual reality da Vinci Skills Simulator exercises. DESIGN: Prospective cohort pilot study. SETTING: Academic hospital-based gynecology training program. PARTICIPANTS: Novice robotic surgeons from a gynecology training program. METHODS: Novice robotic surgeons from an academic gynecology training program completed 10 repetitions of 4 exercises on the da Vinci Skills Simulator: matchboard, ring and rail, suture sponge, and energy switching. Performance metrics measured included time to completion, economy of instrument movement, excessive force, collisions, master workspace range, missed targets, misapplied energy, critical errors, and overall score. Statistical analyses were conducted to define the learning curve for trainees and the optimal number of repetitions for each exercise. RESULTS: A total of 34 participants were enrolled, of which 9 were medical students, 22 were residents, and 3 were fellows. There was a significant improvement in performance between the 1st and 10th repetitions across multiple metrics for all exercises. Senior trainees performed the suture exercise significantly faster than the junior trainees during the first and last repetitions (p = 0.004 and p = 0.003, respectively). However, the performance gap between seniors and juniors narrowed significantly by the 10th repetition. The mean number of repetitions required to achieve performance plateau ranged from 6.4 to 9.3. CONCLUSION: Virtual reality robotic simulation improves ability through repetition at all levels of training. Further, a performance plateau may exist during a single training session. Larger studies are needed to further define the most high-yield simulator exercises, the ideal number of repetitions, and recommended intervals between training sessions to improve operative performance.

Laparoscopy in the morbidly obese: physiologic considerations and surgical techniques to optimize success.

The objectives of this review were to analyze the literature describing the benefits of minimally invasive gynecologic surgery in obese women, to examine the physiologic considerations associated with obesity, and to describe surgical techniques that will enable surgeons to perform laparoscopy and robotic surgery successfully in obese patients. The Medline database was reviewed for all articles published in the English language between 1993 and 2013 containing the search terms "gynecologic laparoscopy" "laparoscopy," "minimally invasive surgery and obesity," "obesity," and "robotic surgery." The incidence of obesity is increasing in the United States, and in particular morbid obesity in women. Obesity is associated with a wide range of comorbid conditions that may affect perioperative outcomes including hypertension, atherosclerosis, angina, obstructive sleep apnea, and diabetes mellitus. In obese patients, laparoscopy or robotic surgery, compared with laparotomy, is associated with a shorter hospital stay, less postoperative pain, and fewer wound complications. Specific intra-abdominal access and trocar positioning techniques, as well as anesthetic maneuvers, improve the likelihood of success of laparoscopy in women with central adiposity. Performing gynecologic laparoscopy in the morbidly obese is no longer rare. Increases in the heaviest weight categories involve changes in clinical practice patterns. With comprehensive and thoughtful preoperative and surgical planning, minimally invasive gynecologic surgery may be performed safely and is of particular benefit in obese patients.

Surgical site infections after hysterectomy among HIV-infected women in the HAART era: a single institution's experience from 1999-2012.

OBJECTIVE: We sought to determine risk factors associated with surgical site infection (SSI) among a cohort of human immunodeficiency virus (HIV)-infected women undergoing hysterectomy during the era of highly active antiretroviral therapy. STUDY DESIGN: This is a retrospective study of HIV-infected women who underwent a hysterectomy for benign indications at a tertiary care center. Electronic medical records were reviewed from January 1999 through December 2012. SSI was defined using Centers for Disease Control and Prevention criteria. RESULTS: There were 77 HIV-infected women who underwent a hysterectomy: 47 (61%) were abdominal; 16 (21%) were laparoscopic or robot-assisted; and 14 (18%) were vaginal. Acquired immune deficiency syndrome was diagnosed in 58% of patients, and 75% of patients self-reported use of highly active antiretroviral therapy at the time of surgery. There were 17 (22%) SSIs; 5 (29%) superficial incisional wound infections, 3 (18%) vaginal cuff cellulitis, and 9 (53%) pelvic abscesses were diagnosed. After multivariable logistic regression, preoperative albumin level (adjusted odds ratio [aOR], 0.14; 95% confidence interval [CI], 0.02-0.86) and minimally invasive hysterectomy (aOR, 0.16; 95% CI, 0.03-0.84) were associated with decreased SSI. Preoperative absolute CD4 count was not associated with SSI (aOR, 0.99; 95% CI, 0.99-1). CONCLUSION: Low preoperative serum albumin levels and abdominal hysterectomy are associated with increased risk of SSIs in HIV-infected women.
