 The introduction of artificial intelligence (AI) into endoscopic practice is progressing. A meta-analysis of multiple randomized controlled trials has shown that computer-aided detection (CADe) of colorectal polyps improves adenoma detection rates by 5-15%. In March 2025, guidelines on colorectal CADe were published jointly by the BMJ, the American Gastroenterological Association (AGA), and the European Society of Gastrointestinal Endoscopy (ESGE). However, despite being based on the same body of evidence, the recommendations differed. This was because, while the cancer-preventive effect of CADe was considered limited, the increased burden on patients from more frequent surveillance colonoscopies was seen as significant.

 Meanwhile, evidence remains insufficient regarding computer-aided diagnosis (CADx) for histopathological prediction and the use of AI in the upper gastrointestinal tract. In 2025, a series of studies were published on learning evidence using AI; however, it remains unclear whether AI contributes to training benefits or, conversely, risks diminishing physicians’ technical skills.

 At present, although there is great anticipation for the technology, evidence established from the patient’s perspective is lacking. Therefore, it is necessary to understand both the efficacy and the limitations/indications of AI and proceed cautiously with its clinical implementation.
