要旨●人工知能（AI）技術の急速な進歩により，日常生活だけではなく内視鏡診療においてもわれわれがAIに触れる場面が増えてきている．大腸内視鏡AIにおいては，その研究開発のスピードには目を見張るものがあり，既にいくつかの製品が規制をクリアし診療で使用できるようになっている．現在研究が進んでいるのは2つのカテゴリーである．すなわちAIによる病変の拾い上げ診断支援（computer-aided detection）と病変の質的診断支援（computer-aided diagnosis）である．いずれも専門医に匹敵する精度が論文などで報告されているが，AIの仕組みそのものに起因する限界があり，過度な期待は禁物である．本稿ではこれまでに報告されている大腸内視鏡AIをレビューし，その有用性と限界について論じる．
