[Personal experience and considerations on duodenal erosions]

Twenty five hundred esophagogastroduodenoscopies were examined, separating all the duodenal erosions' cases. The most important conclusions refer to two facts in relations to the existence of duodenal erosions (DE) with respect to duodenal erosions when coexisting with gastric erosions (gastroduodenal erosions-GDE). In the duodenal erosions symptomatology dominated frankly, mainly ulcerous syndrome, typical or atypical (P less than 0,01). The GDE had a clear predominancy of bleeding referring to DE (P less than 0,01), suggesting that the DE are to be considered a nosologic entity different as the GDE. The ulcerogenious antecedents (drugs, stress, alcohol, etc.) were frankly positive in both cases when there was bleeding, but of low percentage in the cases without bleeding, suggesting that its presence is important in the causing of bleeding but not in the generating erosions in itself.
