Brief Summary:
The aim of this study is to evaluate the clinical benefit and safety of using a computer aided detection device, Skout, for real-time polyp detection in colonoscopy procedures with the indication of screening or surveillance. One of the reasons for the development of interval colorectal cancers is polyps missed during colonoscopy. Our hypothesis is that with the aid of Skout, the adenomas detected per colonoscopy will increase, and it is plausible to believe that this increase in detection could reduce the incidence of interval cancers.

Routine Colonoscopy with the use of Skout
Device: Computer Aided Detection device
The Computer Aided Detection device, Skout, is designed to help endoscopists detect potential colorectal polyps during colonoscopies. The system performs automated real-time analysis on endoscopic video data to identify potential polyps and produces an informational visual aid around the appropriate sections of the video frames on a display monitor.

Primary Outcome Measures :
  1. Adenomas per colonoscopy [ Time Frame: At the end of the procedure, 1 day ]
    The total number of adenomas detected divided by the total number of colonoscopies.

  2. Positive predictive value [ Time Frame: At the end of the procedure, 1 day ]
    The total number of adenomas and serrated lesions detected divided by the total number of extractions.

Secondary Outcome Measures :
  1. Adenoma detection rate [ Time Frame: At the end of the procedure, 1 day ]
    The percentage of participants aged ≥50 years undergoing first-time screening colonoscopy who have one or more conventional adenomas detected.

  2. Sessile serrated lesions detected [ Time Frame: At the end of the procedure, 1 day ]
    The total number of polyps with histology or serrated adenoma, traditional serrated adenoma or serrated lesion with cytological dysplasia, excluding hyperplastic polyps.

  3. Colorectal cancer surveillance interval [ Time Frame: At the end of the procedure, 1 day ]
    The mean recommended timeframe for follow up colonoscopy.

  • Undergoing a procedure by a participating endoscopist.
  • Have given informed consent.

Exclusion Criteria

Participants will not be eligible for this study if they:
