Can my surgeon scope? Trends in endoscopy training volume and experience among general surgery residents in the United States: a nationwide analysis.

INTRODUCTION: Endoscopy is a major part of surgical training. Accreditation Council for Graduate Medical Education (ACGME) has set standards regarding the minimum volume of endoscopy cases required for graduation. However, there is paucity of high-quality data on the number of cases that most surgical graduates perform. METHODS: We conducted a retrospective analysis of operative case logs of all general surgery residents graduating from ACGME-accredited programs from 2010 to 2023. Data on mean number of endoscopy cases, including mean in each subcategory, were retrieved. Mann-Kendall trend test was used to investigate trends in endoscopy experience. RESULTS: Between 2010 and 2023, the mean overall endoscopy procedures per resident remained stable, with 129.5 in 2010 and 132.1 in 2023 (t = 0.429; p-value = 0.037). The majority of these cases were performed as surgeon junior (76.6% in 2010; 80.9% in 2023), while the remaining cases were logged as surgeon chief. The most substantial contribution to the overall volume was from flexible colonoscopy (mean: 64.1 in 2010 and 67.2 in 2023). The volume for colonoscopy remained fairly stable (t = 0.429; p-value = 0.036). This was followed by esophagogastroduodenoscopy (mean: 35.3 in 2010 and 35.5 in 2023), which saw a significant increase in volume (t = 0.890; p-value ≤ 0.001). There was a significant increase in the number of overall upper endoscopic procedures (t = 0.791; p-value ≤ 0.001), while lower endoscopic procedures did not change significantly (t = 0.319; p-value = 0.125). The procedural volume for endoscopic retrograde cholangiography, sigmoidoscopy, cystoscopy/ureteroscopy, laryngoscopy, and bronchoscopy decreased significantly (p-value < 0.05 for all). CONCLUSION: The overall endoscopy volume for general surgery residents has largely remained stable, with a minor increase in esophagogastroduodenoscopy and no change in colonoscopy. Future research should investigate whether simulation-based exercises can bridge the gap between procedural volume and learning curve requirements for endoscopy.

The synergistic role of virtual coaching with simulation-based mastery learning for upper endoscopy.

Introduction: Our simulation-based mastery learning (SBML) curriculum, delivered in person, has been shown to successfully train novices in structured esophagogastroduodenoscopy (EGD). SBML with virtual coaching (VC) has the potential to improve the effectiveness and efficiency of endoscopy training and expand access to trainees from around the world. We share our observations conducting an EGD training course using SBML with VC. Methods: We conducted a 1-week virtual SBML course for novice trainees across seven academic centers in the USA and Asia. The cognitive component was delivered using an online learning platform. For technical skills, a virtual coach supervised hands-on training and local coaches provided assistance when needed. At the end of training, an independent rater assessed simulation-based performance using a validated assessment tool. We assessed the clinical performance of 30 EGDs using the ASGE Assessment of Competency in Endoscopy tool. We compared the trainees' scores to our cohort trained using in-person SBML training using non-inferiority t-tests. Results: We enrolled 21 novice trainees (mean age: 30.8 ± 3.6 years; female: 52%). For tip deflection, the trainees reached the minimum passing standard after 31 ± 29 runs and mastery after 52 ± 37 runs. For structured EGD, the average score for the overall exam was 4.6 ± 0.6, similar to the in-person cohort (4.7 ± 0.5, p = 0.49). The knowledge-based assessment was also comparable (virtual coaching: 81.9 ± 0.1; direct coaching: 78.3 ± 0.1; p = 0.385). Over time, our novice trainees reached clinical competence at a similar rate to our historical in-person control. Conclusions: VC appears feasible and effective for training novice gastroenterology trainees. VC allowed us to scale our SBML course, expand access to experts, and administer SBML simultaneously across different sites at the highest standards.

Implementation and Evaluation of a Curriculum for Ergonomics Training During GI Fellowship.

BACKGROUND AND AIMS: Training in ergonomics is either fragmented or lacking in most GI programs. There are limited real-world data on fellows' perceptions and change in practice after the delivery of a curriculum for ergonomics. We aim to implement a curriculum for endoscopy for our GI fellows and evaluate their response to the same. METHODS: We devised and implemented a curriculum with three components, delivered over 6 months for all GI fellows in an academic hospital center. These were one, a comprehensive, hour-long didactics session conducted by an experienced faculty member; two, an interactive session with a physical therapist; and three, provision of free resistance bands and compression stockings to fellows. We conducted a pre- and post-curriculum test. Data are presented as proportions and medians with interquartile range. RESULTS: We surveyed 23 fellows. At baseline, 13.6% (3) had sustained ERI during their training. Only 63.6% (14) of trainees reported confidence in being able to recognize signs and symptoms of ERI. Their median self-reported understanding of ergonomics was 3 on a Likert scale of 1-5, corresponding with "average understanding." The majority of trainees had never reviewed any material on ergonomics prior to this curriculum. In the post-test evaluation, the median self-reported understanding of ergonomics improved to 4, corresponding with "above average understanding." All fellows requested a repeat of the curriculum, either semi-annually or annually. CONCLUSION: Our data show a positive perception of trainees of a practical, reproducible, and low-cost curriculum for endoscopy incorporated during GI fellowship.

Anatomical endoscopic retrograde cholangiopancreatography simulator using moulded meshed silicone: A novel simulator pilot study.

INTRODUCTION: Endoscopic retrograde cholangio-pancreatography (ERCP) has higher rates of morbidity and mortality compared to upper or lower gastrointestinal tract endoscopy. The availability of magnetic resonance cholangiopancreatography means ERCP is usually performed for therapeutic purposes. Simulation could provide an adjunct to patient-based training in ERCP however models to date have been unconvincing. METHODS: This ERCP simulation model was constructed from moulded meshed silicone by co-designers: Jean Wong and Kai Cheng. The anatomical orientation was based on a combination of anatomical specimens, sectional atlases, and the clinical experience of expert endoscopists. RESULTS: From March to October 2022, we recruited 5 surgeons/gastroenterologists to the expert group and 14 medical students, junior doctors, or surgical/gastroenterological trainees to the novice group. Most experts either agreed or strongly agreed that the simulation anatomy appearance (100%), anatomical orientation (83%), tactile feedback (66%), traversal actions (67%), cannula positioning (66%) and papilla cannulation (67%) resembled the procedure in humans. Experts statistically significantly outperformed novices in obtaining a cannulating position (80% vs. 14%, P = 0.006) and successful papilla cannulation (80% vs. 7%, P = 0.0015) on their first attempt. The novice group had statistically significant improvements in time to obtaining a cannulating position (3.53 vs. 11.5 min, P = 0.006) and passing the duodenoscope to the papilla (2.55 vs. 4 passes, P = 0.009). CONCLUSIONS: The simulator showed statistically significant results in face, content, and construct validity. A follow-up validation study should recruit participants across multiple institutions. External validity could be assessed by comparing expert proceduralist simulator performance against clinical ERCP performance.

A novel smartphone application for the tracking of procedural numbers and trainee experience in gastrointestinal endoscopy.

OBJECTIVES: The tracking and documentation of procedures in gastrointestinal endoscopy including therapeutic interventions is an essential but challenging process. The University of Alberta has developed a smartphone app to help facilitate this task. This study evaluated the functionality, usefulness, and user satisfaction of this app. METHODS: Four Gastroenterology (GI) residents and two therapeutic endoscopy fellows participated in the study. The trainees submitted all their data into the app from the procedures in which they participated hands-on for one year, data was collected and analyzed on the app and the website associated with it. RESULTS: Trainees were able to register the procedures immediately after each procedure without difficulty, this data was available to be reviewed at anytime in the app and associated website. Furthermore, the data collected was able to be transformed into tables and graphs on the app website. The total number of procedures and therapeutic interventions performed were easily accessed in the app and website at anytime. The app facilitated the calculation of the cecal intubation rate in colonoscopy and the cannulation rate in ERCP for the therapeutic endoscopy trainee. Trainees reported excellent experience with the app capabilities. CONCLUSIONS: A novel smartphone app was useful in collecting meaningful data submitted by gastrointestinal endoscopy trainees, furthermore, through an associated website, it was capable to create graphs and tables to show and facilitate the calculation of meaningful data such as key performance indicators.

Study on impact of flexible endoscopy training course for surgeons in India.

Context: Competence in flexible endoscopy is essential for all surgeons during this era of minimal access surgery. However, fewer surgeons have expertise in endoscopy due to a lack of training and interest. The Indian Association of Gastrointestinal Endo Surgeons devised a short-structured training course in the art and science of endoscopy. Aims: This study aimed to find the impact of the endoscopy training course (Endoscopic Fellowship of Indian Association of Gastrointestinal Endo Surgeons [EFIAGES]) in improving the endoscopic skill of surgeons. Settings and Design: Twenty-two-part electronic survey forms were sent to all 375 candidates who took the course between 2016 and 2019 for this retrospective observational study. Subjects and Methods: The following outcome measures were noted, namely technical competence in endoscopy before the course, delegate feedback about the course modules, volume of endoscopies before and after the course and quality indicators such as reaching up to duodenum (D2) and caecum before and after the course. Statistical Analysis Used: Statistical analysis of the impact of the course was done using Chi-square test. Results: Responses from 262 out of a total of 375 candidates were received. Seventy-seven per cent of trainees were pleased with content and mode of conduct of the course. The quality indicator of gastroscopy with the ability to reach D2 in 90% of the caseload was achieved by only 28% of trainees before the EFIAGES. This increased to 72% of candidates after the course and similar results were seen with colonoscopy also. Most of the candidates noted a distinct improvement in their endoscopic navigation skills subsequent to the course. Conclusions: Endoscopy skill transfer was possible with a short-structured endoscopy course. The surgical fraternity should realise the importance of endoscopy skills in the current era of surgical practice.

Mechanistic loop resolution strategy for short-type single-balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography in patients with Roux-en-Y reconstruction after gastrectomy (with video).

BACKGROUND: Endoscopic access to the targeted site is a major challenge for the endoscopic retrograde cholangiopancreatography (ERCP) in patients undergoing Roux-en-Y (R-Y) reconstruction after total or subtotal gastrectomy. We aimed to evaluate the feasibility, reproducibility, and safety of mechanistic loop resolution strategies using a short-type single-balloon enteroscopy (short SBE) system. METHODS: Between February 2020 and March 2022, consecutive patients with a previous R-Y gastrectomy requiring ERCP were prospectively enrolled. Different mechanistic loop resolution strategies for two-dimensional loops, three-dimensionally rotated loops, and loops making a cane or S-shape were applied during the SBE approach. RESULTS: Forty-three short SBE-ERCP procedures were performed on 37 patients, with an approach success rate of 100.0% (43/43). The mean time to reach the jejunojejunal anastomosis and target site were 8.0 (6.0-11.0) minutes and 26.0 (16.0-36.0) minutes, respectively. The major challenges for the approach were the cane or S-shaped loop in the jejunojejunal anastomosis or Treitz ligament. The retroflex positioning of a SBE in front of the papilla was achieved in 86.0% (37/43), and the cannulation success rate in patients with an intact papilla was 90.9% (30/33). The initial, overall therapeutic successes, median total procedure time, and adverse event rate were 87.8%, 92.7%, 77.0 (IQR 56-100.5) minutes, and 11.6%, respectively. CONCLUSIONS: Short SBE-ERCP using standardized mechanistic loop resolution strategies is effective and reproducible in patients with R-Y reconstruction after gastrectomy. TRIAL REGISTRATION: ClinicalTrial.gov (NCT04847167).

Endoscopy Training in Small Animal Internal Medicine: A Survey of Residency Training Programs in North America.

Competency in multiple endoscopic techniques is a major goal of small animal internal medicine (SAIM) residency programs. Training relies predominantly on mentored supervision of procedures performed on patients. Supplementation of this apprenticeship model with classroom sessions and hands-on laboratories can be advantageous to trainees and patients. Few veterinary resources describe supplemental training options, and no single source exists for mentors to consult for program development. The purpose of this study was to describe the supplemental training opportunities currently available to SAIM residents at academic hospitals in the US and Canada and to compare their timing during the residency, resident and faculty time commitment, and perceived helpfulness. Data were collected by an electronic survey distributed to one faculty member per institution. The response rate was 80% (24/30). Most programs (22/24; 92%) offered some form of supplemental training, including classroom sessions (9/24) and hands-on laboratories using physical models (7/24), virtual reality simulators (2/24), and cadaver (2/24) and anesthetized (2/24) dogs. Fifteen programs provided residents with the opportunity to attend external endoscopy workshops. Only three programs required any training prior to residents performing procedures on patients. There was considerable variability in training between programs, precluding statistical comparisons. The survey identified topics for classroom sessions and several inexpensive physical models, rated very or extremely helpful, that would be suitable for programs with limited budgets. A human-based virtual reality simulator was also rated highly by two programs. Comprehensive, external workshops evoked numerous positive comments with perceived value ranging from somewhat to extremely helpful.

A survey of physician training and credentialing in endoscopic submucosal dissection in the United States.

BACKGROUND: Endoscopic submucosal dissection (ESD) is technically challenging, has a longer learning curve and a greater complication rate than most new endoscopic procedures. Formal training and credentialing guidelines for ESD are currently lacking in the United States (US). AIM: To survey ESD experts across the US to determine their learning process and obtain their opinion on how training and credentialing for ESD should develop. DESIGN: Anonymous electronic survey. SUBJECTS: ASGE members who are practicing US endoscopists. METHODS: The survey was developed by iterative revisions of questions administered to three investigators who have been performing ESD for > 5 years. The final survey was distributed electronically to US endoscopists who had previously attended ESD expert conferences. RESULTS: Thirty-five (58.3%) of 60 practicing ESD experts responded to the survey. A majority (91%) were in university-based, community, or tertiary care hospitals. All practitioners practiced on porcine explants and observed live ESD procedures as part of the training. Out of the participants, 75.8% received formal supervised hands-on training on porcine explants and/or humans before performing ESD independently. Fifty percent indicated that their facility had written guidelines specifically for ESD credentialing. Four out of 5 felt that credentialing requirements should include attending weekend ESD courses, observing live procedures, practicing on explants, and advanced endoscopic training in interventional endoscopy such as an additional year of fellowship. LIMITATIONS: Survey completion rate of 58.3%. CONCLUSION: ESD training should include practicing on explants, observation of live procedures, training in interventional endoscopy, and attending educational courses. Credentialing guidelines for ESD based on expert opinion need to be developed in the US.

Application of "upgraded single-entry colonoscope training method" in the primary endoscopic training of refresher doctors / 中华医学教育探索杂志

Objective:To explore the application of "upgraded single-entry colonoscope training method" in the primary endoscopic training of refresher doctors.Methods:A total of 71 refresher doctors who participated in the primary single endoscopy training in the Endoscopy Center of the Affiliated Hospital of Qingdao University from January 2017 to December 2019 were randomized to two groups: upgraded single-entry endoscopy training group ( n=36) and traditional single-entry endoscopy training group ( n=35). In the first week of training, all the participants learned the basic theory of single-entry enteroscopy insertion. From week 2 to week 11, each doctors of the two groups finally completed 80 to 100 cases of single-entry endoscopy. The upgraded single-entry colonoscopy training group was divided into two stages: "rectum-proximal sigmoid colon" and "descending colon-ileocecal part" with the boundary of descending-sigmoid colon as the dividing point, which was different from the traditional group. At the 12th week, each doctors were assessed by 20 cases of single-entry colonoscopy operation. the success rate of ileocecum insertion, the time to pass through sigmoid colon, the rate of loop formation and the average operation time of successful ileocecum insertion were compared between the two groups. SPSS 26.0 was used for t test or chi-square test. Results:Compared with the traditional single-entry endoscopy training group, the upgraded single-entry endoscopy training group achieved better results in the successful rate of ileocecal insertion (66.8% vs. 59.0%, P=0.005), the time to pass sigmoid colon [(6.05±3.32) min vs. (7.15±3.12) min, P<0.001], the loop rate (35.13% vs. 40.71%, P=0.035), the average operation time of successfully inserting the ileocecal part [(9.01±2.12) min vs. (10.25±3.12) min, P<0.001] and the discomfort response score [(5.19±1.41) vs. (6.70±2.15), P<0.001], with statistical significance between the groups. Conclusion:"Upgraded single-entry endoscopy training method" emphasizes no loop through sigmoid colon, which is more helpful for refresher doctors to master the operation skills of single-entry colonoscopy, shorten the teaching time, and reduce the discomfort of patients, and is suitable for popularization in the teaching.

The Role of National Specialist Societies in Influencing Transformational Change in Low-Middle Income Countries - Reflections on the Model of Implementation for a National Endoscopy Training Programme in Bangladesh.

The British Society of Gastroenterology (BSG) and the Bangladesh Gastroenterology Society (BGS) have collaborated on an endoscopy training programme, which has grown up over the past decade from a small scheme borne out of the ideas of consultant gastroenterologists in Swansea, South Wales (United Kingdom) to improve gastroenterology services in Bangladesh to become a formalised training programme with broad reach. In this article, we document the socioeconomic and historical problems that beset Bangladesh, the current training needs of doctors and how the BSG-BGS collaboration has made inroads into changing outcomes both for gastroenterologists in Bangladesh, but also for the populations they serve.

Simulation training for the endoscopic management of upper gastrointestinal bleeding: a nationwide survey of rural surgeons' needs and preferences analysis.

BACKGROUND: Published needs analyses of rural surgeons have identified a need for training in the endoscopic management of non-variceal upper gastrointestinal bleeding (NVUGIB). The study aim was to survey rural surgeons regarding their requirements and preferences for a simulation model on which they could rehearse the endoscopic management of NVUGIB. METHODS: Rural surgeons were contacted via the American College of Surgery Advisory Council listserv and invited to complete an online survey. RESULTS: A total of 66 responses were received, representing all 4 US regional divisions. Seventy-seven percent of respondents perform > 100 endoscopy cases per year. A majority have no experience with simulation models (77%), citing cost, time, and access to training courses as the three most limiting factors. Thirty-three percent lacked confidence in managing UGIBs, and 73% were interested in receiving additional training. Preference analysis revealed that respondents preferred a portable simulation model (81%) that costs between $500 and $1000 (46%), and requires 1-2 weeks of training (34%). Verbal feedback from an expert was viewed as the most helpful type of feedback (61%). CONCLUSION: Rural surgeons frequently perform flexible endoscopy in their practice and are interested in further training for the endoscopic management of NVUGIB. These results will be used to develop a simulation platform for training in the endoscopic management of NVUGIB that meets rural surgeons' needs.

Influence of COVID-19 Pandemic on Endoscopic Procedures in Two European Large-Capacity Endoscopy Units: "Keep Calm, Keep Safe and Scope on?"

BACKGROUND: The COVID-19-pandemic poses challenges to the medical system and especially to endoscopic staff and patients. National, European and International societies provided recommendations on how to safely perform endoscopic procedures during the current pandemic. Until now, the effect of the current pandemic on tertiary endoscopy centers has not been reported. OBJECTIVE: The aim of this was to analyze the influence of the early SARS-CoV2-pandemic on endoscopic care and work flow in 2 European tertiary endoscopy units. METHODS: Data from 2 tertiary endoscopy units (Katowice and Munich) were retrospectively collected during the early pandemic and compared to an equivalent pre-pandemic period. Data include procedures, complications, benchmarks, and influence on endoscopy training. RESULTS: During the early pandemic, we noted a highly significant decrease (49.1%) in the overall number of all endoscopies with a significant increase in therapeutic procedures. Besides, there were no significant differences in the number of urgent endoscopic retrograde cholangiopancreatography or interventional endoscopic ultrasound procedures. The exceptional situation reduced endoscopic procedures performed by trainees significantly. CONCLUSIONS: The SARS-CoV2-pandemic halved the endoscopy service of 2 tertiary centers while maintaining an urgent therapeutic service. Recommended personal safety measures in endoscopy proved to be efficient and safe in preventing SARS-CoV2 infection of staff or spreading. Unnecessarily, the SARS-CoV2 pandemic prevented routine endoscopy training.

Endosonographers performing on-site evaluation of solid pancreatic specimens for EUS-guided biopsy: A formal training method and learning curves.

OBJECTIVES: This study aimed to examine the effects of a training program combining formal cytological curriculum and practical assessments on endosonographers and to determine how many operations were needed for training through learning curves. METHODS: A formal cytological curriculum was implemented in November 2019 for four endosonographers. The competency of endosonographers before and after the curriculum was judged by quantitative scores. From December 2019 to October 2020, trainees independently examined the adequacy and atypia grade of pancreatic specimens acquired by EUS-guided-fine-needle biopsy based on specific atypical grading criteria. The accuracy of the adequacy and atypia assessment of each trainee was calculated, and learning curves were drawn to evaluate the improvement. RESULTS: The median posttraining score improved by 87% from 49 to 91.5 out of 100. Ninety patients were enrolled in the practical assessments. The accuracy for specimen adequacy and atypia assessment of each trainee was 91.7%, 92.8%, 91.0%, and 89.3% and 80.0%, 82.1%, 81.0%, and 78.9%. The learning curves of each trainee showed a steady and significant improvement, and ninety cases were sufficient for satisfactory adequacy assessment. CONCLUSIONS: Basic knowledge of on-site cytopathologic evaluation can be gained through standardized and systematic training. Practical assessments showed that, at the completion of ninety cases, trained endosonographers reached a satisfactory level of recognizing specimen adequacy, but continue practice was needed for atypia assessment.

Training in bariatric and metabolic endoscopy.

The limited penetration of bariatric surgery and the scarce outcome of pharmacological therapies created a favorable space for primary bariatric endoscopic techniques. Furthermore, bariatric endoscopy is largely used to diagnose and treat surgical complications and weight regain after bariatric surgery. The increasingly essential role of endoscopy in the management of obese patients results in the need for trained professionals. Training methods are evolving, and the apprenticeship method is giving way to the simulation-based method. Existing simulation platforms include mechanical simulators, ex vivo and in vivo models, and virtual reality simulators. This review analyzes current training methods for bariatric endoscopy and available training programs with dedicated bariatric core curricula, giving a glimpse of future perspectives.

Impact of a simulation-based induction programme in gastroscopy on trainee outcomes and learning curves.

BACKGROUND: Pre-clinical simulation-based training (SBT) in endoscopy has been shown to augment trainee performance in the short-term, but longer-term data are lacking. AIM: To assess the impact of a two-day gastroscopy induction course combining theory and SBT (Structured PRogramme of INduction and Training - SPRINT) on trainee outcomes over a 16-mo period. METHODS: This prospective case-control study compared outcomes between novice SPRINT attendees and controls matched from a United Kingdom training database. Study outcomes comprised: (1) Unassisted D2 intubation rates; (2) Procedural discomfort scores; (3) Sedation practice; (4) Time to 200 procedures; and (5) Time to certification. RESULTS: Total 15 cases and 24 controls were included, with mean procedure counts of 10 and 3 (P = 0.739) pre-SPRINT. Post-SPRINT, no significant differences between the groups were detected in long-term D2 intubation rates (P = 0.332) or discomfort scores (P = 0.090). However, the cases had a significantly higher rate of unsedated procedures than controls post-SPRINT (58% vs 44%, P = 0.018), which was maintained over the subsequent 200 procedures. Cases tended to perform procedures at a greater frequency than controls in the post-SPRINT period (median: 16.2 vs 13.8 per mo, P = 0.051), resulting in a significantly greater proportion of cases achieving gastroscopy certification by the end of follow up (75% vs 36%, P = 0.017). CONCLUSION: In this pilot study, attendees of the SPRINT cohort tended to perform more procedures and achieved gastroscopy certification earlier than controls. These data support the role for wider evaluation of pre-clinical induction involving SBT.
