摘　　要：目的:探讨内镜窄带成像技术(NBI)诊断Barrett食管的价值。方法:选择2008年8月至2009年8月间48例经胃镜检查病理诊断的Barrett食管患者,分别在普通内镜模式和NBI模式下,观察食管黏膜病变轮廓并计算图像清晰度评分,在病变处靶向下取活检进行病理检查。结果:普通内镜模式下发现病变33例(68.8%),NBI模式下发现病变41例(85.4%),NBI模式对病变的检出率高于普通内镜模式(P<0.05)。普通内镜模式下病变轮廓清晰度评分总分为61分,而NBI模式下总分为114分,两者图像清晰度评分有显著差异(P<0.01),NBI优于普通内镜。结论:NBI技术操作简便,对Barrett食管病变轮廓显示清晰,有助于对病变处进行靶向病理活检。Objective： To evaluate the value of narrow-band imaging （NBI） in the diagnosis of Barrett＇s esophagus. Methods： 48 patients diagnosed with Barrett＇ esophagus by gastroscopies and pathological examinations were ob- served under the ordinary edoseopy and NNI respectively. The silhouette of the esophageal mucosal lessions were cal- culated and scored in terms of the clearity of the image. Besides, the target lesions was taken to be biopsied and pathologically examined. Results： The lesions of only 33 patients （68. 8%） were detected by ordinary endoscopy, while the lesions of 41 patients （85.4%） could be detected by NBI endoscopy. The lesion detecting rate by NBI was much higher than that by the ordinary endoscopy （P^0. 05）. The total score of lesion＇s silhouette detection is only 61 points under the examinatin of ordinary endoscoy, while 114 points under NBI. There were significant differences in the score between the two methods （P^0. 01）. It turned out that NBI was more effective in detecting Barrett esophagus than ordinary endoscope did. Conclusions： NBI is very easy to operate and has a clear lesion silhouette of Barrett esophagus, which helps to target the lesion at pathological biopsy.
