Introduction:
We report a prospective pilot of GI Genius ColonPro 4.0 (Medtronic, Minneapolis, MN), the first US Food and Drug Administration-approved computer-aided quality (CAQ) platform for colonoscopy.
Methods:
ColonPro measurements of withdrawal time, cecal intubation, and Boston Bowel Preparation Score (BBPS) were compared with independent video review in 110 outpatient colonoscopies.
Results:
Agreement between the CAQ and physicians was poor for BBPS (intraclass correlation coefficient = 0.40, P < 0.001) but strong for withdrawal time (intraclass correlation coefficient = 0.89, P < 0.001) and cecal intubation (κ = 0.79, P < 0.001).
Discussion:
CAQ reliably measures withdrawal time and cecal intubation, but artificial intelligence-based BBPS scoring requires further validation before integration into current paradigms of colonoscopy quality.
