[Catarrhal stomatitis of the gastric stump. Histological changes]

The prospective investigation here presented tries to show the histologic changes produced in the endoscopic mucosal erythema zone of the gastric stump, which is the largest exposition and reactivity site to which the duodenal-biliary reflux damages. 56 clinically asynthomatic patients have been studied through directed biopsy. The observed results are: great prevailing of chronic gastritis and a high percentage of intestinal metaplasia which, in both cases are in close correlation with the age of the patient and not with his surgical age. There is not any relation either with age or intensity in the different degrees of dysplasia. We came to the conclusion that the erythema does not constitute by it self a histologic perfile different from the rest of the remaining gastric stump.
