| 【 要旨 】 | 新しい画像強調観察としてBLI (Blue Laser Imaging)やLCI (Linked Colar Imaging)がある．BLIは表面微細構造および微小血管構築像が高いコントラストで描出され，LCIは粘膜のわずかな色の違いを強調した画像が描出される．大腸腫瘍に対するBLI拡大内視鏡観察の診断能についてはNBI拡大観察分類を用いることによる有用性がいくつか報告されている．過去にNBI併用拡大観察の統一分類であるJNET分類を用いた報告はなかったが，今回，当院で行った大腸病変に対するBLIとNBIの正診率の比較検討において差は認めなかった． LCIによる拡大内視鏡観察の有用性についてはまだ明確に示されておらず，今後の検討に期待したい． |

| [ Summary ] | Blue laser imaging (BLI) and Linked color imaging (LCI) have emerged as new forms of image enhanced endoscopy. BLI can enhance the contrast of surface vessels using lasers for light illumination. LCI can detect images with enhanced brightness and varied colors. A number of reports have shown the usefulness in terms of diagnostic ability, of magnifying endoscopy with BLI (M-BLI) for colorectal lesions. Those reports applied previous classifications used for magnifying endoscopy with narrow band imaging (M-NBI). The usefulness of diagnostic ability of M-BLI has not been reported, using the Japan NBI Expert Team (JNET) classification which unified many previous classifications of MNBI. We showed there were no differences in diagnostic ability for colorectal lesions between M-BLI and M-NBI using JNET classification in our hospital review. The diagnostic ability of magnifying endoscopy with LCI (M-LCI) has not been reported. We look forward to future research on the diagnostic ability of M-LCI. |
