Abstract Background and study aims Training in endoscopy is a key objective of gastroenterology residency. There is currently no standardized or systematic training approach. This study evaluated and compared the current status of gastrointestinal endoscopy training programs in all teaching hospitals in the Netherlands from a resident perspective. Materials and methods A national online survey with open and closed questions on gastrointestinal endoscopy training was administered to all gastroenterology residents (N = 180) in the eight educational regions in the Netherlands. Results One hundred residents who had already started endoscopy training were included in the analyses. Sixty-five residents (65 %) were satisfied with their endoscopy training program. Participation in a preclinical endoscopy course was mandatory in seven of eight educational regions. Residents from the region without a mandatory endoscopy training course were significantly less likely to be satisfied with their endoscopy training program (32 %, P = .011). Criteria used to determine the level of supervision differed greatly between teaching hospitals (e. g. assessed endoscopy competence, predefined period of time or number of procedures). Only 26 residents (26 %) reported uniformity in teaching methods and styles between different supervising gastroenterologists in their teaching hospital. Conclusions Although most gastroenterology residents were satisfied with the endoscopy training program and endoscopy supervision in their teaching hospital, this study identified considerable local and regional variability. Future studies should be conducted to evaluate the trainers’ perspective and trainers’ behavior during endoscopy training sessions, which might eventually lead to the development of best practices regarding endoscopy training, including standardization of training programs and supervision methods.
