The application value in diagnosis of chronic atrophic gastritis using the magnifying endoscopy and narrow-band imaging

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 narrow-band 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. Key words: Endoscopy/MT; Gastritis, atrophic/DI
