摘　　要：目的探讨窄带成像放大内镜(narrow band imaging-magnifying endoscopy,NBI-ME)对胃粘膜肠上皮化生诊断的临床价值。方法选取行普通内镜联合NBI-ME检查的慢性胃炎患者110例,并对可疑病变区域取病理化验,以病理学结果为金标准评价上述联合检查方法诊断胃粘膜肠上皮化生的准确性。结果经NBI-ME诊断肠上皮化生的敏感性为88.22%,特异性为96.05%,阳性预测值为90.91%,阴性预测值为94.81%,阳性似然比为22.33,阴性似然比为0.12,约登指数为0.84。结论普通内镜联合窄带成像放大内镜可明显提高胃粘膜肠上皮化生的诊断准确率,值得临床推广。Objective To study the clinical value of the narrow band imaging-magnifying endoscopy（ NBI-ME） applied to the diagnosis of gastric mucosal intestinal metaplasia. Methods 110 patients with chronic gastritis ,who come from the First Hospital of the Shanxi Medical Univercity ,were observed by the ordinary endoscopy combined with NBI-ME and taken pathological tests in of suspicious lesions area.Pathology Results was deemed as the gold standard to evaluate the above joint method the accuracy. Results The result of NBI-ME inspection in diagnosis of intestinal metaplasia showed the sensitivity of 88.22%, speciifcity of 96.05%, positive predictive value 90.91%, negative predictive value of 94.81%, positive likelihood ratio of 22.33, negative likelihood ratio of 0.12, about the index of 0.84. Conclusion The ordinary endoscopy combined with NBI-ME can obviously improve the diagnosis of gastric mucosal intestinal metaplasia, and was worth promoting in clinic.
