We aimed to develop and validate an all-in-one hybrid model for stepwise learning in multiple EUS interventions.<\/jats:p><jats:p>\n          Methods\u2002A hybrid model was created utilizing a pig esophagus and stomach, a silicon-based duodenum and pancreato-biliary system, a pseudocyst, and biopsy targets. This model was designed to provide hands-on training in multiple interventional EUS procedures, such as EUS-guided fine-needle biopsy (EUS-FNB), biliary drainage (BD), pancreatic duct drainage (PD), pseudocyst drainage (PSD), and gastro-enterostomy (GE). Thirty-six trainees underwent training on this model over 6 days, in two batches. Lumen apposing metal stents were used for PSD and GE. Trainees were assessed for objective criteria of technical difficulties. Subjective assessment by trainees was done via a questionnaire.<\/jats:p><jats:p>\n          Results\u2002All the trainees were able to complete the requisite steps for all the procedures under supervision. On subjective assessment, 30 trainees (83\u200a%) graded the model as good or excellent. A total of 107 technical difficulties were noted (scope position 55, duct puncture 27, guidewire-related problems 25). Time taken to complete the requisite steps of biopsy, PSD, and GE (10.5 minutes; range 3.5 to 22) was significantly less than that for BD and PD (28 minutes; range 17 to 40) (P\u200a&lt;\u200a0.001).<\/jats:p><jats:p>\n          Conclusions\u2002The hybrid model provided training for multiple EUS interventions with good acceptance by trainees. Stepwise mentoring with the possibility of performing multiple procedures in a single model with or without X-ray could prove useful in conference as well as institutional settings.<\/jats:p>","DOI":"10.1055\/a-1784-3978","type":"journal-article","created":{"date-parts":[[2022,5,13]],"date-time":"2022-05-13T22:30:15Z","timestamp":1652481015000},"page":"E634-E643","source":"Crossref","is-referenced-by-count":9,"title":["Evaluation of an all-in-one hybrid model (EUS Magic Box) for stepwise teaching and training in multiple interventional EUS procedures"],"prefix":"10.1055","volume":"10","author":[{"given":"Vinay","family":"Dhir","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, School of EUS, Institute of Digestive & Liver Care, S.
