Summary
Brief summary (as posted)
This study is a clinical validation of PolyDeep, a computer-aided polyp detection (CADe) and characterization (CADx) system. PolyDeep Advance 2 is a multicentric randomized clinical trial with a tandem colonoscopy design. The hypothesis of this study is that Polydeep assisted colonoscopy will reduce the number of missed adenomas in the first withdrawal.
