In resected portions of the stomach we find chronic atrophic gastritis of the corpus only in 10% of the patients with duodenal ulcers, and chronic inflammatory changes are, contrary to patients with a gastric ulcer, less marked. The difference is statistically significant. Consistent with some other authors, we find that great progression of chronic inflammatory changes occurs in patients operated on account of duodenal ulcers in the course of the first three years after operation. From six cases of regression of chronic inflammatory changes after operation, in two cases undetected atrophic gastritis was involved which was present in a severe form in the body of the resected portion beyond the vicinity of the gastric ulcer. According to the author's findings regression of atrophic gastritis is possible. The high score of chronic inflammatory changes in the antrum of gastric resectates (3.54) and in the close vicinity of gastric ulcers (4.0) confirms the frequency of severe antral gastritis in peptic ulceration and the intensity of the focal inflammation in the vicinity of gastric ulcers.
