窄带成像结合放大内镜在慢性萎缩性胃炎诊断中的应用

摘要

目的 探讨窄带成像结合放大内镜(NBI-ME)在慢性萎缩性胃炎(CAG)诊断中的应用价值.方法比较经普通白光胃镜和ME-NBI诊断为CAG患者的胃镜和组织学检查结果.结果普通白光胃镜诊断CAG患者108例中,最终经组织学检查确诊者49例,诊断符合率为45.37%.NBI-ME诊断CAG患者83例中,最终经组织学检查确诊者65例,诊断符合率为78.31%,后者高于前者(<0.05).伴肠上皮化生型CAG在普通白光胃镜组的检出率为18.52%,在NBI-ME组的检出率为37.35%,NBI-ME组高于普通白光胃镜组(<0.05).结论NBI-ME诊断CAG与组织学的符合率比普通白光胃镜高,对伴肠上皮化生型CAG的符合率更高.%Objective To explore the value of narrow-band imaging and magnigying endoscopy in the diagnosis of chronic atrophic gastritis. Methods Endoscopic and histological findings in patients with CAG diagnosed by convention white light endoscopy and ME-NBI were compared. Results In 108 cases of patients with CAG diagnosed by convention white light, 49 cases were confirmed the diagnosis by histological examination eventually, diagnosis coincidence rate was 45.37%. In 83 patients with NBI diagnosis of CAG, 65 cases were confirmed the diagnosis by histological examination eventually, diagnosis coincidence rate of 78.31%, which was significantly higher than that of the former group ( <0.05). The detection rate of CAG in convention white light group was 18.52%, and the detection rate was 37.35% in NBI-ME group and NBI-ME group was significantly higher than that in normal group ( < 0.05). Conclusions The coincidence rate of NBI-ME and histology is higher than that of convention white light endoscopy, and the coincidence rate of CAG with intestinal metaplasia is higher than that of CAG.
