[HYSTOLOGICAL FEATURES IN NODULAR GASTRITIS EXPERIENCE IN CAYETANO HEREDIA NATIONAL HOSPITAL]
Histopathologic findings in Nodular Gastritis at Cayetano Heredia National Hospital.Nodular Gastritis (NG) is not a so unfrequently finding in adults. From January 1994 to April 1997, 261 patientes from a total number of 3600 that were submitted to an upper endoscopy at Cayetano Heredia National Hospital in Lima, Per , had this finding. The aim of this study is to find whether there is a characteristic histopathologic pattern in NG. Material and methods : 112 endoscopy reports with the diagnosis of NG that at the same time had biopsies, were reviewed. These patients were compared to a group matched for age and sex with an endoscopic finding of normality, or a diagnosis different from NG, excluding diagnosis of gastric or duodenal ulcers, duodenitis or neoplasia, that had also biopsies. The biopsies of both groups were reviewed by an experimented pathologist in a double blind fashion. The following parameters were considered : Presence and type of gastritis, presence and grade of mucosal inflammation, presence and type of intestinal metaplasia, presence and degree of inflammatory activity, presence and number of lymphoid follicles, presence and number of eosinophils in the mucosa, presence of Helicobacter pylori and edema.RESULTS : Significative statistic difference was found in the group of patients with NG on the following parameters: grade of mucosal inflammation, gastritis activity, presence of eosinophils and presence of Helicobacter pylori. Conclusion : NG is a chronic gastritis with superficial eosinophilic infiltration and a very important inflammatory activity associated to the presence of Helicobacter pylori. Further studies are required to determine the cause for these histopathologic findings.
