[The morphostructural disorders of the gastric mucosa in peptic ulcer].

200 patients with ulcerative disease of the stomach have been examined. It is indicated that 87% of patients showed chronic gastritis, more often with mucosal atrophy. 7.9% of patients revealed isolated dysplasia of various expression degree, in 38.2%--isolated regenerative disturbances, and in 24.3%--associations of dysplasia with regeneration defects. 9.5% of patients showed malignant ulcer (with atrophic and atrophic hyperplastic gastritis--in 13.8% of cases, and with isolated dysplasia--in 41.7%, with isolated regenerative disturbances--in 5.2%, with association of dysplasia and regenerative defects--in 29.7%). To determine resection value one should account extensions morpho-structural alterations in gastric mucosal membrane.
