Pathogenesis and classification of peptic ulcer

: The authors present data on the mechanism of ulcer formation in stomach and duodenum in patients with ulcer disease. The pathogenesis of ulcer disease is complicated and far from being solved. It is suggested that ulcerogenesis of ulcer disease is only a link of the pathogenesis of ulcer disease. Ulcer defect of the gastric and duodenal mucosa is the main morphological sign of ulcer disease but not the complete symptom complex of systemic disorders in the body which along with ulcerogenesis are the essence of ulcer disease. A working classification of ulcer disease is presented.
