Brief 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.
Detailed Description:
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.
In this randomized controlled trial, endoscopists will be assigned to one of three arms: no CADx assistance, CADx assistance without predicted probability, or CADx assistance with predicted probability. The CADx system provides NICE-based histology predictions (Type 1 vs Type 2), which endoscopists may use to support optical diagnosis and subsequent management decisions, including surveillance interval recommendations when applicable. Outcomes will compare endoscopist-level pass rates and diagnostic performance metrics relevant to PIVI-based adoption, with histopathology as the reference standard where applicable.
