[Periodic gastric and duodenal motility in peptic ulcer patients after selective proximal vagotomy].

The condition was studied of intermittent motility (IM) of the stomach and duodenal bulb in patients with duodenal ulcer in the preoperative period, six months later and 12 months after performing selective proximal vagotomy (n = 131, 103, and 83 respectively). All patients presented with disorders in their IM which were found to be dependent on their preoperative condition failing to reverse even 6 to 12 months after having the operation.
