Background: As flexible endoscopy is increasingly adopted as a minimally invasive approach to surgical challenges, an efficient curriculum is needed to train surgeons in therapeutic endoscopy. We developed a simulation-based approach to teaching endoscopic management of gastrointestinal hemorrhage as part of a modular curriculum, complete with task performance pre- and post-testing.
Methods: Two sessions of our advanced flexible endoscopy course were taught using ex vivo porcine models to simulate active gastrointestinal hemorrhage and allow for training in hands-on endoscopic management. The module is composed of hands-on pretesting, didactics, mentored practice sessions, and postcourse assessments. Pre- and postcourse tests and surveys evaluated knowledge, confidence, and performance of participants and results were analyzed using the paired t test.
Results: Sixteen practicing surgeons participated in the course. After course completion, overall knowledge-based assessments improved from 3.4 (±1.9) to 5.8 (±2.0) (P < .001). Although participants with glove sizes >7.0 and ≥2 years in practice had higher pretest evaluator scores (P = .045 and P = .020), all participants demonstrated overall improvement in endoscopic management of hemorrhage, with postcourse evaluator score increases from 20.9 (±1.6) to 23.6 (±2.0) (P = .001) and specific improvements in identification of target bleeding (P = .015), endoscopic clip setup (P < .001), and clip deployment (P = .002). Surveys also found increased confidence in competency after curriculum completion, 11.6 (±3.4)-23.0 (±5.5) (P < .001).
Conclusion: Our simulation-based approach to teaching the endoscopic management of gastrointestinal bleeding emphasizes hands-on pretesting and provides an effective training model to improve the knowledge, confidence, and technical performance of practicing surgeons.
