Five- to Eight-year Results of Truncal Vagotomy and Pyloroplasty for Duodenal Ulcer

From January 1963 to December 1965 inclusive 192 men with duodenal ulcer were treated by elective truncal vagotomy and pyloroplasty with one death. Ten subsequent deaths were due to causes unrelated to the ulcer or operation, and 17 patients became untraceable. The remaining 164 patients have been followed up for five to eight years. The late results have been compared with those obtained in a previous study of patients five to eight years after truncal vagotomy and gastroenterostomy, truncal vagotomy and antrectomy, and subtotal gastrectomy respectively for duodenal ulcer.Of the various postgastric operation syndromes early dumping, late dumping, bilious vomiting, and diarrhoea were all less frequent, but not significantly so, after vagotomy and pyloroplasty than after vagotomy and gastroenterostomy.Recurrent ulceration was commoner after vagotomy and pyloroplasty than after all the other operations, the incidence of proved and suspected recurrent ulcers being respectively 6·7 and 7·3% after vagotomy and pyloroplasty, but only 2·5 and 5·9% after vagotomy and gastroenterostomy, 0 and 5·2% after vagotomy and antrectomy, and 0·9 and 3·7% after subtotal gastrectomy. The differences between vagotomy and pyloroplasty and vagotomy and antrectomy or subtotal gastrectomy are statistically significant, but those between vagotomy and pyloroplasty and vagotomy and gastroenterostomy are not.Overall assessment (Visick grading) of the outcome gave poorer results after vagotomy and pyloroplasty than after any other operation, with 14% of category IV cases after vagotomy and pyloroplasty, 11% after vagotomy and gastroenterostomy, 8% after vagotomy and antrectomy, and 6% after subtotal gastrectomy—differences that are significant between vagotomy and pyloroplasty and vagotomy and antrectomy or subtotal gastrectomy but not between vagotomy and pyloroplasty and vagotomy and gastroenterostomy.In the light of these findings it is suggested that truncal vagotomy and pyloroplasty has not lived up to expectations and its place as the currently most popular procedure in the elective surgical treatment of duodenal ulcer should be reconsidered.     

Mortality after Vagotomy and Pyloroplasty for Duodenal Ulcer

A retrospective survey of 4,026 patients having truncal vagotomy and pyloroplasty for duodenal ulceration showed a mortality rate of 1·4% (55 patients). On analysis the commonest causes of death were found to be bronchopneumonia 37% (18 patients) and sepsis 20% (10 patients). More than half of the deaths occurred in patients aged over 50.     

Emergency Vagotomy and Pyloroplasty for Perforated Duodenal Ulcer: Study of 73 Cases

Seventy-three unselected patients with perforated duodenal ulcer were treated by vagotomy and pyloroplasty in a six-year period. Postoperative complications were commoner when the operation was carried out after more than six hours after perforation. The follow-up results were similar to those for elective vagotomy and pyloroplasty carried out in the hospital during the past nine years.     

Incidence of Dumping after Truncal and Selective Vagotomy with Pyloroplasty and Highly Selective Vagotomy without Drainage Procedure

The incidence of dumping after truncal or selective vagotomy with pyloroplasty and highly selective vagotomy without a drainage procedure was assessed both clinically and experimentally. At a gastric follow-up clinic dumping was found to be significantly less frequent in patients who had undergone highly selective vagotomy without a drainage procedure than in patients who had undergone truncal or selective vagotomy with pyloroplasty (P < 0·05 or < 0·001, respectively). Hypertonic glucose given by mouth provoked the onset of dumping in 20% of patients with duodenal ulcer before operation, in 73% after truncal vagotomy and pyloroplasty, in 80% after selective vagotomy and pyloroplasty, and in 47% after highly selective vagotomy. The test meal also produced significantly greater decreases in blood pressure and increases in pulse rate in patients who had undergone vagotomy with pyloroplasty than in patients who had undergone highly selective vagotomy.     

Vagotomy for Gastric Ulcer

Out of a series of 75 patients who were treated by vagotomy and drainage for gastric ulcer 66 have been followed up for one to seven years (average three-and-a-half years). Four recurrent gastric ulcers occurred among the 33 cases of ulcer of the lesser curve or body with no antral or duodenal lesion (type I). Among the 42 patients with an antral ulcer or an associated active or healed pyloric or duodenal lesion (type II or III) there was only one recurrence. The recurrence rate for men was 5% and for women 12%. One patient died two years after operation from cancer which may have originated in the stomach. The clinical results in patients without recurrences were generally satisfactory.Vagotomy, preferably selective, with drainage is a satisfactory operation in gastric ulcers of types II and III. For ulcers of type I, gastrectomy is to be preferred except in selected cases.
