Abstract:
Objective To explore the diagnostic value of magnifying endoscopy in the identification of chronic atrophic gastritis (CAG) , intestinal metaplasia (IM) and Helicobacter pylori ( Hp) infection. Methods Microstructures of gastric mucosa in 140 cases with different gastric diseases were studied using Olympus GIF-Q240Z magnifying endoscope. Biopsies were taken from the magnified sites. The microstruc-tures of gastric mucosa were compared with the results of pathological study. Results The morphology of gastric pits was classified as follows: Types A ( round spot) , B ( short rod) , C ( branched) , D ( patchy) and E ( villous) . The detection rate of CAG by magnifying endoscopy was 94. 3% (33/35) , which was significantly higher than that by routine endoscopy (22. 8% , 8/35) (P
