Abstract
The study was performed to demonstrate possible relations between gastric emptying rate for fluid meals and the completeness of vagotomy after truncal vagotomy and pyloroplasty for duodenal ulcer. Seventy-three patients with postcibal symptoms or recurrence after this operation were examined by a fluid nutritional contrast medium several months later, and insulin tests were performed on the 10th day and 2 to 4 years after the operation. A retrospective analysis revealed no relation between the completeness of the vagotomy and the gastric emptying rate, but an increase in spontaneous acid secretion with decreasing emptying rate. Also, patients with recurrence had a lower emptying rate than those with non-recurrence.
