[Stomach motor evacuatory function in duodenal ulcer patients following selective proximal vagotomy].

Motor-evacuatory stomach function by using continuous radiogastrography was studied in 89 patients with duodenal ulcers. Altogether 131 radiogastrograms were analyzed, of them 57 before operation, 84 on the 7th-15th day after selective proximal vagotomy performed either independently or in combination with draining operations. A faster evacuation of food from the stomach prevailed in an uncomplicated form of duodenal ulcer and compensated stenosis of the pyloroduodenal zone, evacuatory stomach function was retarded or absent in subcompensated and decompensated stenosis. Discoordinated gastric peristalsis and a reverse food input were noted in patients with subcompensated stenosis. At early time after operations temporary inhibition of evacuatory stomach function occurred in 94.2% of the patients; it could be corrected with conservative therapeutic measures.
