What this Trial Is About
Researchers are evaluating whether using artificial intelligence (AI)-assisted colonoscopy can reduce the risk of developing advanced colonic lesions during follow-up colonoscopies. The study focuses on patients who previously underwent either AI-assisted or conventional colonoscopy to see if AI technology decreases the likelihood of metachronous advanced lesions over time. Participants will have surveillance colonoscopies to monitor for the presence of advanced colonic lesions after their initial colonoscopy. This procedure is the main intervention being studied, and the trial compares outcomes between those who previously had AI-assisted colonoscopy and those who had standard colonoscopy. Throughout the study, participants will undergo surveillance colonoscopy at intervals to assess the development of colonic lesions. Researchers will measure the cumulative risk of metachronous advanced lesions over three years, along with secondary outcomes such as the number and types of adenomas and serrated lesions detected. The trial includes safety monitoring and informed consent, with participation lasting at least three years from the initial procedure.
