Long-term results of selective vagotomy plus pyloroplasty: 12 to 17 year follow-up

Abstract

Among an initial series of 103 patients with selective vagotomy plus pyloroplasty for duodenal ulcer, 9 patients died of causes unrelated to ulcer and 7 were lost to follow-up without signs or symptoms of ulcer 8 to 15 years after operation; the remaining 87 patients were followed up for 12 to 17 years. Insulin testing revealed only one inadequate vagotomy in a patient who had a recurrence in the short term. Insulin tests were negative in 61 and negative or adequate in 6 other patients. Complete vagotomy reduced basal secretion effectively in the great majority of patients but not in a small minority. Three patients had antral hyperfunction with persistent hypersecretion despite complete vagotomy as indicated by two negative insulin tests in each patient. Inexplicably, only one of these patients had a stomal ulcer recurrence. Long-term follow-up revealed the development of gastric ulcer in one patient with stasis from a pyloroplasty stenosed by angulation from adhesions. Three other patients, one with ulcer and two with hemorrhagic gastritis, developed gastric ulceration in the long term despite low acid output and negative insulin tests. Biliary reflux was demonstrated in two of these three patients and was probably the cause of gastric ulcer in the third. Pre- and postoperative cholecystograms in 66 patients showed the formation of gallstones in 4 patients after vagotomy. Another patient who did not undergo cholecystography developed acute cholecystitis from stone. This rate of gallstone formation was the normal expected rate and was not increased as in some series of total vagotomy. Dumping with and without associated diarrhea was the most frequent and troublesome sequela. Postvagotomy diarrhea did not occur. To prevent dumping, and also to decrease acid secretion more effectively, pyloroplasty was abandoned in favor of Maki's pylorus-preserving antrectomy to complement selective vagotomy in 1968.
