[Triple site biopsy under endoscopy].

TL;DRAbstract

Triple site biopsy specimens were taken from antrum, corpus, and supraangle simultaneously in 3002 Japanese cases to compare the differences among the biopsy sites for the evaluation of mucosal atrophy and inflammation. The prevalence of H. pylori infection was almost same in biopsy specimens from the different sites, but the detective rates for mucosal atrophy and intestinal metaplasia were remarkably higher in the supraangle. Our results indicate that the antral and the corpal biopsy are suitable for the evaluation of inflammation and H. pylori infection, but the supraangular biopsy is more reliable for the recognition of mucosal atrophy and intestinal metaplasia than the antral and the corpal biopsy.
