Drug therapy for postvagotomy gastric stasis

Abstract

An unusual but well-recognized complication of truncal vagotomy with a drainage procedure is severe gastric stasis (atony). In 6 patients presenting with this problem drug therapy was initiated after mechanical obstruction of the gastric outlet was excluded by radiology. Bethanechol chloride was successful in stimulating gastric peristalsis in all the patients, with consequent improvement of symptoms in 5 out of the 6 subjects. Metoclopramide alone was of no value in starting peristalsis but of possible benefit once gastric motility had begun.
