摘　　要：目的探讨窄带成像放大内镜诊断胃黏膜肠上皮化生的临床价值。方法观察窄带成像放大内镜下的胃黏膜淡蓝色嵴,并与其肠上皮化生的病理组织学结果进行对照研究,对其两者之间的相关性进行评价。结果用淡蓝色嵴诊断胃黏膜肠上皮化生的敏感性为88.46%,特异性为91.03%,准确性为90.00%;阳性预测值为86.79%,阴性预测值为92.21%。结论通过窄带成像放大内镜下观察淡蓝色嵴,对胃黏膜肠上皮化生进行诊断有很高的准确性。Objective The aim of the present study was to clarify the value of narrow band imaging system with magnifying endoscopy for diagnosing gastric intestinal metaplasia. Methods A light blue crest （LBC） was defined as a fine, blue-white line on the crests of the epithelial surface/gyri. The degree of correlation between the LBC and histology of intestinal metaplasia was assessed. Results The appearance of LBC correlated with histological evidence of intestinal metaplasia with sensitivity of 88.46%, specificity of 91.03%, accuracy of 90%, positive predictive value of 86.79%, and negative predictive value of 92. 21%. Conclusion In narrow band imaging with magnifying endoscopy, observation of a light blue crest on the epithelial surface in the gastric mucosa is a highly accurate sign of the presence of histological intestinal metaplasia.
