Assessment of Endoscopic Tip Control Using a Novel Score Based on Snare Tip Soft Coagulation of ex Vivo Model (HAM STUDY)

Introduction: Colorectal cancer (CRC) is a significant global health concern, with colonoscopy being the primary screening tool for its detection and treatment. Endoscopic techniques such as snare tip soft coagulation (STSC) play a crucial role in reducing adenoma recurrence post-resection. However, assessing endoscopists' proficiency in tip control during these procedures remains challenging. This study aims to develop and validate a web-based scoring system to objectively evaluate endoscopist tip control during STSC application. Research Questions: * Can STSC application on an ex vivo model effectively measure endoscopic tip control across different levels of endoscopists' experience? * Is there a correlation between tip control and endoscopists' polypectomy experience? * Does tip control vary based on endoscopists' specialization? * Can training on the STSC model improve endoscopists' tip control? * Is it feasible to train an AI model using videos scored by expert raters to assess tip control? * Can tip control be used as an objective measure to predict endoscopists' future performance? Research Hypothesis: The investigators hypothesize that developing a model for easy tip control assessment will enable endoscopists to evaluate their proficiency and track progress. Training on the STSC model will enhance tip control, and cut-offs for tip control derived from preliminary data will be refined through this study.
