Brief Summary:
The investigators hypothesize that the clinical implementation of an AI system is an optimal tool to monitor, audit and improve the detection and classification of polyps during colonoscopy. The objectives of this study are to generate preliminary data to evaluate the effectiveness of AI-assisted colonoscopy on: a) the rate of detection of adenomas; b) the histological classification of polyps (which would reduce the need for pathological evaluation of polyps); c) the performance of endoscopists in detecting polyps and in the accuracy of polyp classification.

Arm Intervention/treatment
Experimental: Artificial intelligence for real-time detection and monitoring of colorectal polyps
A standard colonoscopy will be performed according to the standard of routine care. All optically diagnosed polyps will be removed and sent to the CHUM pathology laboratory for histopathological evaluation according to institutional standards. The AI system will capture video of the procedure in real time, and provide additional information on the detection of polyps, follow-up and prediction of pathology.
Diagnostic Test: Polyps detection by Artificial Intelligence
The AI system will capture the live video of the procedure and the AI feedback (polyp detection, tracking, and pathology prediction) will be shown on a second screen installed next to the regular endoscopy screen. Screen A will show the regular endoscopy image and screen B will show the regular endoscopy image together with the areas that might harbor a polyp or the information to predict pathology

Primary Outcome Measures :
  1. Efficacy of detection of adenomas [ Time Frame: Day 1 ]
    Efficacy of AI assisted colonoscopy to detect the proportion of patients with at least 1 neoplastic polyp. Adenoma detection rate with an AI.

Secondary Outcome Measures :
  1. Incomplete resection rate (IRR) [ Time Frame: Day 1 ]
    proportion of incomplete polyp resections proportion of patients with either adenoma or carcinoma rate and type of adverse and serious adverse events occurring during the procedure.

  2. prediction of polyp histology [ Time Frame: Day 14 ]
    evaluate the agreement of the optical diagnosis-based surveillance interval with the pathology-based recommendation assessing the prediction accuracy of advanced neoplasia proportion of patients for whom an immediate surveillance recommendation following the colonoscopy can be directly provided when using AI-assisted optical diagnosis and how often histopathology polyp examination would have been avoided by using this strategy.
