[Acid-forming function of the stomach and the effectiveness of vagotomy in the surgical treatment of complications of duodenal ulcer evaluated by pH-metry].

Ninety patients with perforations and hemorrhaging duodenal ulcers were examined. It was established that the intragastric pH-metry in patients with acute complications of the ulcer disease allowed to approximately estimate the acid formation in the stomach and the completeness of vagotomy just in the course of urgent operations. The acid forming function of the stomach can be changed in 21,3% of the patients within the nearest 6 months.
