[Gastric emptying in patients with pyloroduodenal ulcers after selective proximal vagotomy].

The method of roentgen planimetry was used in 79 patients with pyloroduodenal ulcer at different terms after selective proximal vagotomy (SPV) with/without draining operations in order to study the rate of emptying the stomach. It was shown that the evacuatory function of the stomach in remote periods after isolated SPV was determined by the state of the closing function of the pylorus, after SPV with drainage of the stomach--by a draining operation. Alterations of the duodenal passage not corrected during operation manifested themselves in remote periods after SPV as slower emptying of the stomach.
