摘　　要：目的探讨内镜窄带成像技术(NBI)在早期胃癌中的诊断价值.方法将155例患者的局灶性病变(黏膜形态异常,黏膜色泽异常)纳入研究,排除进展期胃癌、黏膜下病变及既往有胃手术史患者.结果病变轮廓观察:NBI与染色内镜或普通内镜之间结果比较差异具有统计学意义,NBI最清晰,特别是对于局灶性浅表性病变的观察;胃小凹的形态观察结果:NBI或染色内镜均优于普通内镜,对于胃黏膜微血管的观察NBI具有绝对的优势,155例患者中发现轻度异性增生16例,中度异性增生7例,重度异性增生3例,早期胃癌3例.结论 NBI技术操作简单,能够清晰显示胃黏膜轮廓,经放大可清晰观察到胃小凹及微血管形态,能有效提高早期胃癌及异性增生检查的准确性.Objective To investigate the values of narrow band imaging（ NBI） in the diagnosis of early gastric cancer. Method A total of 155 patients with lesions（ abnormal mucosal morphology and color） were involved in the study. Patients with advanced gastric cancer,submucosal lesions had underwent gastric surgery. Results The observation on the pathological changes showed a significant difference between NBI and the staining endoscopy or the ordinary endoscope,in which the clearness with NBI was the most obvious,especially for the observation of focal superficial lesions; the morphological observation of gastric pits showed that NBI or chromoendoscopy was better than ordinary endoscopy and NBI had an absolute advantage for the observation of gastric mucosa microvasculature; there were 16 cases of mild dysplasia,7 cases of moderate dysplasia,3 cases of severe dysplasia and 3 cases of early gastric cancer among the 155 cases. Conclusion NBI technology has the advantages of simple operation. It can clearly show the outline of gastric mucosa; the gastric pits and capillary pattern can be more clearly observed,and it can effectively improve the examination accuracy of early gastric cancer and dysplasia.
