Impact of CADx on Endoscopists' Histologic Characterization of Diminutive Colorectal Polyps
Sponsor: Shanghai Jiao Tong University School of Medicine
Summary
This study evaluates the impact of CADx assistance on endoscopists' histologic characterization of diminutive colorectal polyps (≤5 mm) during colonoscopy. The primary objective is to determine whether CADx assistance increases the proportion of endoscopists who meet PIVI-related performance thresholds, thereby supporting implementation of the "resect and discard" and "diagnose and leave" strategies in routine clinical practice.

CADx-Assisted Endoscopic Diagnosis System Without Predicted Probability Display
CADx-assisted optical diagnosis (NBI; predicted probability not displayed). Endoscopists perform optical diagnosis of diminutive colorectal polyps (≤5 mm) during colonoscopy using narrow-band imaging (NBI) with CADx-displayed NICE classification predictions for each polyp. In this arm, the CADx output is displayed without any predicted probability information.
