Training endoscopists to recognize and interpret resection scars after polyp removal
Official title: Detection of Endoscopic Resection Scars and Delineation of Recurrence Amongst Non-experts is Less Accurate Than Experts But Trainable in a Short Learning Intervention
Run by University Hospital, Ghent · NCT06193356 · Data updated 2026-11-12
This study tests whether an online training tool helps endoscopists of any experience better detect recurrent or residual adenoma at endoscopic resection scars using images from colonoscopy.

Is this trial a fit for you?
✓Likely a good fit
Ideal participants are practicing endoscopists of any experience level who perform colonoscopy and polypectomy and can complete an online survey.
✕Probably not a fit
Non-endoscopists, clinicians who do not perform colonoscopy, or those unwilling to complete the online training or survey are unlikely to receive benefit from this intervention.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Practicing endoscopists who consent will complete an online survey that begins with a pseudonym and basic demographic and experience questions. Participants will first review a set of endoscopic images of EMR resection sites and record whether they believe recurrent or residual adenoma is present. They will then receive a focused learning intervention and repeat image review to measure changes in recognition. Pre- and post-training performance will be compared against expert-labeled images and available histopathology where provided.
Why it matters
Potential benefit: If successful, the training could help endoscopists more reliably detect recurrent or residual adenoma at resection scars, reducing missed lesions and potentially lowering post-colonoscopy colorectal cancer risk.
How similar studies have gone: Expert series and imaging studies report high negative predictive value for careful scar inspection, but data on general endoscopists and formal training interventions are limited.
