[The acid-forming function of the stomach and its hormonal regulation after truncal and combined vagotomies].

The acid-producing function of the stomach and the state of its hormonal regulation were assessed on the basis of the immediate and long-term follow-up results obtained after truncal (334 patients) and combined (96 patients) vagotomy for duodenal ulcer. According to the data of aimed endoscopic pH-metry and gastroimpedancemetry the acid level changes in different parts of the stomach and duodenum were the same at the nearest and remote periods as well as the dynamics of the main hormones responsible for the acid production.
