A modular simulation curriculum to teach endoscopic stenting to practicing surgeons: an "Into the fire" approach.

Background: Flexible endoscopy is a valuable tool for the gastrointestinal (GI) surgeon, creating a need for effective and efficient training curricula in therapeutic endoscopic techniques for trainees and practicing providers. Here, we present a simulation-based modular curriculum using an "into the fire" approach with hands-on pre- and post-testing to teach endoscopic stenting to practicing surgeons.
Methods: Three advanced flexible endoscopy courses were taught by expert surgical endoscopists from 2018 to 2019. The stenting module involved using self-expandable metal stents to manage simulated esophageal and gastroduodenal strictures on a non-tissue GI model. Based on the educational theories of inquiry-based learning, the simulation curriculum was designed with a series of pre-tests, didactics, mentored hands-on instructions, and post-tests. Assessments included a confidence survey, knowledge-based written test, and evaluation form specific to the hands-on performance of endoscopic stenting.
Results: Twenty-eight practicing surgeons with varying endoscopic experiences participated in the course. Most of the participants (67.9%) had completed over 100 upper endoscopic procedures and 57.1% were certified in Fundamentals of Endoscopic Surgery. After completing the modular curriculum, participant confidence survey scores improved from 11.4 ± 4.2 to 20.7 ± 4.0 (p < 0.001). Knowledge-based written test scores also improved from 7.1 ± 1.2 to 8.4 ± 0.9 (p < 0.001). In terms of technical performance, overall hands-on performance scores improved from 21.3 ± 2.7 to 28.9 ± 1.2 (p < 0.001) with significant improvement in each individual component of the assessment (all p values < 0.01) and the greatest improvement seen in equipment handling (88%) and flow of procedure (54%).
Conclusion: Our modular simulation curriculum using an "into the fire" approach to teach endoscopic stenting is effective in improving learner knowledge, confidence, and hands-on performance of endoscopic stenting. This approach to simulation is effective, efficient, and adaptable to teaching practicing surgeons with varying levels of experience.
