Training endoscopists to recognize and interpret resection scars after polyp removal
Detection of Endoscopic Resection Scars and Delineation of Recurrence Amongst Non-experts is Less Accurate Than Experts But Trainable in a Short Learning Intervention
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.

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.
Who should consider this trial
Good fit: Ideal participants are practicing endoscopists of any experience level who perform colonoscopy and polypectomy and can complete an online survey.
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.
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 performed: 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.
