[Duodenal ulcer in adolescents].
The author describes the clinical features as well as the endoscopic and morphological pictures of the gastric and duodenal mucosa in adolescents with peptic ulcer of the duodenum. Attention is also drawn to a number of exogenous and endogenous factors in the disease genesis. It is shown that the times of ulcer healing depend to a large degree on its sites, size, disease standing and concomitant deformation. The importance of endoscopy in the diagnosis of ulcer and concomitant pathology in adolescents is emphasized.
