ABSTRACT

Objective To explore the application value in diagnosis of chronic atrophic gastritis using the magnifying endoscopy and narrow-band imaging.Methods A total of 98 cases of chronic atrophic gastritis patients was selected,and carried out the ordinary white light endoscopy,magnifying endoscopy and narrow-band imaging(ME-NBI) and pathological examination in file,followed by comparison of the results.Results The sensitivity and specificity of chronic atrophic gastritis by magnifying endoscopy and narrowband imaging mode were 74.07％ and 82.35％,respectively;which were significantly higher than that obtained by conventional endoscopy,which were 48.15％ and 64.71％ (P ＜0.05).In magnifying endoscopy and narrow-band imaging endoscopy group,60 patients were positive,which intestinal metaplasia accounted for 35％,while in conventional endoscopy group,39 patients were positive which was only 17.95％ (P ＜ 0.05).Conclusions Magnifying endoscopy and narrow-band imaging can improve the diagnostic accuracy of chronic atrophic gastritis.
