Interventional prospective multicenter study: Polyp detection by an automated endoscopic tool as second observer during routine diagnostic colonoscopy

This is an investigator-initiated multicentre non-randomized prospective interventional trial to validate the performance of a novel state-of-the-art computer-aided diagnostic (CAD) tool in polyp detection implemented as second observer during routine diagnostic colonoscopy and to evaluate its feasibility in daily endoscopy. Patients referred for a screening surveillance or therapeutic colonoscopy will undergo a colonoscopy performed by an endoscopist with moderate to high adenoma detection rate (ADR > 20% and < 50%) while a second observer will follow the procedure on a bedside AI-tool to count the number of detections made by the AI system and categorize the results into positive or negative results as follows (1) true positive, (2) false negative, (3) other positive and (4) obvious false positive. When a doubtful detection is made by the AI-system, the second observer will ask to re-evaluate the indicated region. When the detection is clear, the endoscopist and second observer do not communicate. The entire procedure is recorded.
