This study examined the fraction of patients undergoing colonoscopy with versus without artificial intelligence (AI) in 9 randomized controlled trials (6 parallel and 3 tandem) to determine the number of patients whose recommended surveillance interval was 3 years because of increased detection with AI. Adhering to U.S. and Japanese guidelines, which are similar, the fraction of patients with recommended 3-year surveillance intervals increased from 8.4% without AI to 11.3% with AI, for an absolute difference of 2.9% and a relative increase of 35%. Using the European guidelines, the fraction increased from 6.1% to 7.4%, for an absolute difference of 1.3% and a relative increase of 22%.

COMMENT

Increased numbers of surveillance colonoscopies and their associated cost and risk is always a consequence of an increased adenoma detection rate (ADR). Of course, the entire goal of high-quality colonoscopy is to maximize ADR and cancer prevention; in previous modeling, reduction of cancer risk associated with higher ADR offsets the cost of more colonoscopies.
