摘　　要：目的:探讨内镜窄带成像技术(narrow-band imaging endoscopy,NBI)对早期胃癌的诊断价值.方法:97例患者分为两组,普通内镜组50例,N B I组47例,观察局灶性病变形态、色泽及微血管形态,并结合病理学检查结果分析评价两种检查方法早期胃癌的发现例数及诊断的准确性.结果:普通内镜组萎缩性胃炎伴肠化生9例,异型增生5例,早期胃癌3例.NBI组萎缩性胃炎伴肠化生11例,异型增生6例,早期胃癌5例.N B I对胃微血管形态和黏膜表面细微结构的显示更清晰,且在异型增生和早期胃癌的诊断准确率方面明显优于普通内镜(P<0.05).结论:NBI有助于提高早期胃癌及异型增生的诊断率.AIM：To evaluate the diagnostic value of narrow-band imaging（NBI） endoscopy in early gastric cancer.METHODS：Ninety-seven patients with gastric disease were divided into two groups,an ordinary endoscopy group（50 cases） and an NBI group（47 cases）.The shape,color and microvascular morphology of focal lesions were observed.Using the results of pathological examination as the golden standard,the accuracy of the two imaging modalities in the diagnosis of early gastric cancer was compared.RESULTS：In the ordinary endoscopy group,we found atrophic gastritis with intestinal metaplasia in nine cases,dysplasia in five cases,and early gastric cancer in three cases.In the NBI group,we found atrophic gastritis with intestinal metaplasia in 11 cases,dysplasia in six cases,and early gastric cancer in five cases.NBI showed greater advantage in the observation of microvascular and mucosal fine structures,and the diagnostic accuracy rate of NBI for dysplasia and early gastric cancer was better than that of ordinary endoscopy（P 〈0.05）.CONCLUSION：NBI is helpful in improving the diagnosis rate of early gastric cancer and dysplasia.
