A randomized controlled trial reported that AI significantly reduced the miss rates for gastric neoplasms, but real-world implementation studies have shown inconsistent results. This discrepancy cannot be explained solely by technical limitations. Regardless of the AI capabilities, the visualization quality and systematic inspection remain fundamental prerequisites, and traditional apprenticeship training cannot be replaced by technology. This review examines AI implementation in endoscopy from a human-AI interaction perspective. Two cognitive phenomena are relevant: 'automation neglect,' where experienced endoscopists dismiss AI recommendations due to overconfidence or distrust, and 'automation bias,' where users over-rely on AI outputs, potentially missing unhighlighted lesions. Recent evidence raises concerns regarding deskilling, with studies showing decreased diagnostic performance after exposure to AI. A systematic analysis of 52 human-AI teaming studies showed that none achieved ideal complementarity, and collaboration sometimes decreased accuracy compared to humans alone. AI effectiveness varies according to operator expertise. High-performing endoscopists gain minimal benefit, while those with intermediate experience show the greatest improvement. Nevertheless, excessive false-positive alerts can negate benefits. Strategies to address these challenges include explainable AI, human-centered design, structured education, trust calibration, and expertise-tailored AI systems. Maintaining human expertise remains paramount. AI is a powerful tool, but clinicians must remain the final decision maker. Periodic AI-free practice may be necessary to preserve clinical competence.</p>","PeriodicalId":94245,"journal":{"name":"The Korean journal of gastroenterology = Taehan Sohwagi Hakhoe chi","volume":"86 1","pages":"1-9"},"PeriodicalIF":0.8,"publicationDate":"2026-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12834635/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146032236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Endoscopic retrograde cholangiopancreatography with pancreatic sphincterotomy, stenting, and stone extraction is the mainstay of therapy.

As therapeutic endoscopic procedures become increasingly complex, there is a growing demand for enhanced precision, stability, and control beyond the capabilities of conventional endoscopes. In response, various robotic endoscopic platforms have been developed to improve visualization, dexterity, and procedural safety, particularly for technically demanding interventions such as endoscopic submucosal dissection (ESD). Robotic therapeutic endoscopy systems can be broadly categorized into multitasking robotic platforms and robotic add-on platforms. Multitasking platforms enable bimanual manipulation, triangulation, and effective tissue traction but are often limited by high cost, system complexity, and workflow constraints. In contrast, robotic add-on platforms are designed to integrate with conventional endoscopes, offering improved maneuverability and traction with minimal disruption to clinical practice. Recent preclinical and early clinical studies, including first-in-human and randomized pilot trials, have demonstrated the feasibility and safety of robotic-assisted ESD, with potential benefits in procedural efficiency, learning curve reduction, and operator workload. Despite ongoing challenges related to cost-effectiveness, device integration, and widespread commercialization, robotic endoscopy represents a promising therapeutic platform.
