[Role of Helicobacter pylori in the etiology of duodenal ulcer recurrence after selective proximal vagotomy].

126 patients with duodenal peptic ulcer were examined before and in different periods after operation for selective proximal vagotomy (SPV). Endoscopy was performed and Helicobacter pylori (HP) was detected by the urease, bacteriological, and histological methods. The urease test proved to be the most informative, simple, and available method for revealing infection of the gastric mucosa by HP. The frequency of HP detection by this method made up 97-98%. The frequency of ulcer recurrences after SPV coincided with the degree of contamination of the mucosa with HP and increased to 15% in high contamination. Treatment with agent eliminating HP in the early period after SPV promoted cicatrization of the ulcer.
