Anderson Professor of Medicine, Mayo Clinic Florida</p><p>Artificial intelligence (AI) is rapidly transforming the field of gastrointestinal (GI) endoscopy, enhancing diagnostic accuracy, efficiency, and workflow optimization. AI-driven technologies, including deep learning algorithms and computer-aided detection and diagnosis (CADe/CADx), are being increasingly integrated into endoscopic practice, particularly in areas such as adenoma detection, polyp classification, Barrett's esophagus evaluation, early gastric cancer detection, indeterminate bile duct strictures, and bowel preparation classification. This review explores these key areas and the implications of AI on endoscopic workflows.</p><p>Colorectal cancer (CRC) prevention relies heavily on the detection and removal of adenomatous colon polyps during colonoscopy. AI-powered CADe systems have been developed to enhance adenoma detection rates (ADR) by identifying subtle lesions that may be overlooked by endoscopists. Studies have shown that AI-assisted colonoscopy increases ADR, reduces polyp miss rates, and improves overall procedural quality. By providing real-time visual alerts and bounding boxes around suspected polyps, AI enables more effective and standardized detection.</p><p>Beyond detection, AI plays a critical role in polyp characterization (CADx), aiding endoscopists in distinguishing between neoplastic and non-neoplastic lesions. AI algorithms trained on large datasets of histologically confirmed polyps can provide real-time classification, potentially reducing the need for unnecessary polypectomies. Technologies such as narrow-band imaging (NBI) and confocal laser endomicroscopy, when combined with AI, can enhance the accuracy of in vivo histological assessments. While nearly all polyps in the proximal colon should be removed endoscopically, making pre resection diagnosis less relevant, there remains a value in the rectosigmoid where small hyperplastic polyps can be left in Situ when the endoscopist is confident that they are hyperplastic. Furthermore, large polyps must be stratified into those that are noninvasive, superficially invasive, and deeply invasive to guide therapies such as standard endoscopic mucosal resection, endoscopic submucosal dissection and surgery respectively.</p><p>AI has also been recently shown to facilitate polyps size classification which is notoriously variable and has impact on surveillance recommendations particularly for polyps 10 mm or larger.
