准确诊断胃肿瘤的分界线(DL)对于通过内窥镜粘膜下剥离术(ESD)进行瘤体完切至关重要。在ESD之前,只进内镜诊断胃肿瘤的DL是有争议的。近日,一项前瞻性的单中心研究评估了仅使用放大内镜联合蓝激光成像(M-BLI)与同时使用M-BLI和活检确认对胃腺瘤和分化良好的腺癌的DL的诊断准确性,研究结果已发表于Dig Dis。

2015年7月至2016年12月期间,研究纳入了96个分化良好的腺癌和32个胃腺瘤。共有122个在M-BLI上有明确DL的病变被随机分配到仅接受M-BLI(M-BLI组)或M-BLI与活检确认(M-BLI-BC组),在ESD前从病变外≈5毫米的非癌组织的4个方向进行活检。主要目的是确定在诊断准确性和完全切除方面,没有活检确认的M-BLI与有活检确认的M-BLI相比是否有劣势。

 

结果显示,两组之间在性别、中位年龄、肤色、周长、大体类型、基于活检的诊断和幽门螺杆菌感染方面没有显著差异。M-BLI和M-BLI-BC组的DL诊断准确率分别为100和95.0%,完全切除率均为100%。

综上,该研究结果表明,M-BLI的诊断能力在诊断胃腺瘤和分化良好的腺癌的分界方面非常好。对于这些病变,通过M-BLI明确的DL,不需要进行活检确认。
