[Morphological changes in the gastric mucosa in patients with peptic ulcer of different localisation].

Morphological changes were studied of gastritis in patients with ulcer localized in the upper, middle thirds of the stomach, in its antral segment, and in patients with ulcer in the bulb of duodenum, the former two groups of patients displaying mild inflammation/activity if any, the latter ones showing a high to moderate degree of inflammation and activity of gastritis identifiable in the antral segment of the stomach. The findings secured can be helpful in the diagnosis of gastritis of different localization, prognostication of the course of the illness, and adoption of adequate therapy.
