Helicobacter pylori after proximal selective vagotomy

: The authors examined histologically in 40 patients after proximal selective vagotomy on account of duodenal ulceration specimens of the antral mucosa for the presence of Helicobacter pylori. The latter was detected in 38 (95%) patients. The intensity of colonization evaluated semiquantitatively was not directly related to the dyspeptic complaints. No relapses of ulcers were observed and the author's experience does not confirm the theory of a direct part played by Helicobacter in the manifestation of duodenal ulceration in patients after proximal selective vagotomy.
