[Investigations on the correlation between gastritis and gastric ulcer (author's transl)]

From 200 gastric ulcer-patients and 200 controls stepwise mucosa-biopsies were taken. Grade and expansion of gastritis were determined and correlated with the location of gastric ulcer and gastritis-grade at the margin of ulcer. Intensity and expansion of gastritis vary with the location of ulcer. Gastritis far from ulcer is equally or even more intense as at the margin of ulcer. There is no evidence for the conclusion, that an ulcer develops at the site of the more pronounced gastritis. There is also no evidence to assume, that gastritis forms the base for development of gastric ulcer.
