| 【 要旨 】 | 12人の医師が大腸腫瘍12病変のNBIまたはFICE拡大写真のみで内視鏡所見の判定と推定病理診断を行い，内視鏡所見判定の一致率と病理についての内鏡診断能を算出した．隆起型病変における内視鏡所見判定の一致率はsurface pattern，vascular patternともに高いが，病理についての内視鏡診断能は低かった．表面型病変における内視鏡所見の一致率はsurface patternは比較的高く，vascular patternでは血管の途絶所見のみ一致率が高かった．病理についての内視鏡診断能は比較的高く，血管の途絶所見の存在が癌診断に役立っていた． | |

| [ Summary ] | Twelve endoscopists independently evaluated twelve colonic neoplasms, using only magnified NBI or FICE images. Endoscopic findings and speculative histopathological diagnoses were required for development of interobserver agreement and diagnostic accuracy. In elevated type of lesions, observer agreement concerning endoscopic findings was high in relation to surface and vascular patterns, but low in relation to histopathological diagnostic speculation. In superficial type of lesions, interobserver agreement of endoscopic findings was relatively high in relation to surface patterns. Only vascular interruptions were observed in vascular patterns. There is a high probability of speculative histopathological diagnostic ability with this technique. Findings indicating vascular interruption contributed to diagnoses of cancer. |
