[Endoscopic control of patients subjected to vagotomy and drainage for duodenal ulcer. Personal experience].

The usefulness of endoscopic examination of patients subjected to vagotomy and drainage for duodenal ulcer is stressed, since it permits recurrences and ineffective treatment to be detected, along with the control of other parameters, such as the appearance of the mucosa, the performance of gastric drainage, the features of peristalsis and gastric tone, and the performance of the cardial sphincter. Data from a series of 43 endoscopies performed after 192 vagotomy and drainage operations carried out between 4-1973 and 5-1976 are presented.
