Abstract:
Objective To study H.pylori infection and the changes of muco sal inflammation， atrophy and intestinal metaplasia in the different histolog ical types of gastric polyps. Methods Two hundred and seventy－ eight cases of gastric polyps(12.6％ ) from 2 203 gastric mucosal biopsy cases were histologic ally classified and examined for the presence of Helicobacter pylori,for degree and type of inflammation,mucosal atrophy and intestinal metaplasia. Results 53. 9％ gastric polyps were infected with H.pylori,in which faveolar polyp was the highest with an infective rate of 73.1％ .The changes of active inflammation,atr ophy and metaplaisa in gastric mucosa were frequently accompanied with H.pylori positive faveolar polyps almost as same as those in adenoma.The fundic gland pol yps were usually with low rate of H.pylori infection,and the changes of mucosal active inflammation,atrophy and metaplasia were seldom observed. Conclusions Fav eolar polyps,which are different from fundic gland polyp,may caused by H.pylori infection and are usually with the changes of mucosal active inflammation,atroph y and metaplasia.
