要旨●拡大内視鏡観察と通常観察(色素内視鏡を含む)による早期胃癌の範囲診断能を検討した.2014年4月〜2018年3月までESD適応と考えられ,拡大内視鏡観察にて精査を行った218病変を対象とした.全周で正診できた病変は通常観察では65.1%,NBI併用拡大内視鏡観察(ME-NBI)では98.6%であった.また通常観察では17%の病変で1/2周以上で境界が不明瞭であり,術前に生検を行い切除範囲決定する必要があると考えられた.平坦型病変で通常観察だと,10.6%と正診率が低かったが,ME-NBIだと純粋0-IIb,随伴0-IIb病変にかかわらず,97.0%であり,高い正診率であった.以上の結果から術前範囲診断にはME-NBIは必須である.
