[Acid-forming function of the stomach in duodenal ulcer after vagotomy].

Under analysis was the dynamics of pH-metry indices in patients with the ulcer disease of the duodenum in different terms after vagotomy. The continuous decompensated acid formation of high intensity has been established to be typical for this localization of ulcer. At the early terms after vagotomy it had a considerably decreased intensity. The maximally inhibited gastric secretion was observed within 3-5 months after vagotomy.
