窄带成像技术是一种利用滤光片进行RGB顺序照明，使光谱透过率带宽变窄的新技术。NBI能够观察胃肠道浅表粘膜中的微细毛细血管。在这份报告中，作者评估了NBI放大在结直肠肿瘤小凹模式诊断中的临床实用性。共分析了90例结直肠病变，包括9例增生，60例管状腺瘤和21例早期癌。根据世界卫生组织分类进行组织学诊断。采用NBI对病变进行磁共振成像观察，记录小凹形态诊断。在内窥镜或手术切除病变后，作者进行了立体检查，以确认小凹模式。根据这些数据，作者估计了使用NBI放大而不使用色素内镜诊断小凹模式的能力。非色素内镜下NBI放大与立体检查结果的符合率分别为：II型100%（9/9），III型100%（56/56），IV型100%（3/3），Vi型80%（12/15），Vn型57%（4/7）。无色素内镜下NBI放大对结直肠肿瘤的小凹形态诊断有良好的效果，尤其是对小凹形态规则的病变。
Narrow band imaging (NBI) is a newly developed technology that uses optical filters for RGB sequential illumination and narrows the bandwidth of spectral transmittance. NBI enables the observation of the fine capillaries in the superficial mucosa of the gastrointestinal tract. In this report, the authors assessed the clinical usefulness of NBI magnification in pit pattern diagnosis for colorectal neoplasia. A total of 90 colorectal lesions including nine cases of hyperplasia, 60 of tubular adenoma and 21 of early carcinoma were analyzed. Histologic diagnosis was undertaken according to World Health Organization classifications. Magnified observation of the lesions was performed using NBI without chromoendoscopy, and pit pattern diagnosis was then recorded. After endoscopic or surgical resection of the lesion, the authors performed stereoscopic examination to confirm the pit pattern. From these data, the authors estimated the ability to diagnose pit patterns using NBI magnification without chromoendoscopy. The correspondence rate of pit pattern diagnosis between NBI magnification without chromoendoscopy and stereoscopic findings was 100% (9/9) for type II, 100% (56/56) for type IIIl, 100% (3/3) for type IV, 80% (12/15) for type Vi, and 57% (4/7) for type Vn. NBI magnification without chromoendoscopy demonstrated good results for pit pattern diagnosis of colorectal neoplasia, especially for lesions with regular pit pattern.
