Endoscopic Tip Control Using a Novel STSC Scoring System (HAM Study)
Official title: Assessment of Endoscopic Tip Control Using a Novel Score Based on Snare Tip Soft Coagulation of ex Vivo Model (HAM STUDY)
Run by University Hospital, Ghent · NCT07609017 · Data updated 2026-11-12
This study tests a web-based scoring system to measure how well endoscopists control the snare tip during STSC on an ex vivo model, using training to see if skill improves.

Is this trial a fit for you?
✓Likely a good fit
Digestive endoscopists at any level of training who can provide informed consent.
✕Probably not a fit
Patients are not directly involved in this ex vivo training study, and those not receiving endoscopic procedures may not benefit.

What this trial studies
Researchers will evaluate endoscopists with varying experience performing snare tip soft coagulation (STSC) on an ex vivo model, recording videos to score tip control. Participants undergo a training session between assessments to see if performance improves. The study defines primary endpoints around the accuracy and speed of tip control and agreement among expert raters, with secondary endpoints focusing on training-related improvement. An online app and a panel of six expert raters will assess performance, and analyses will be conducted in R with pseudonymized data stored securely. The goal is to develop a standardized, objective assessment tool for endoscopist tip control during STSC application.
Why it matters
Potential benefit: If successful, the scoring system could standardize training and credentialing for STSC, potentially improving procedural safety and effectiveness.
How similar studies have gone: Previous work has shown that objective scoring and training can improve technical skills in endoscopy, though this specific ex vivo STSC tip-control scoring approach is novel.
