Proximal gastric vagotomy: update
Abstract:
Experience with proximal gastric vagotomy at the Mayo Clinic from 1973 to Mayo 1980 is reported. Among 298 patients who had proximal gastric vagotomy for chronic duodenal, pyloric channel, or prepyloric ulcers, a recurrent ulcer rate of 7% was present, with a mean follow-up of 49 months. Three recurrences developed in six patients who had proximal gastric vagotomy for gastric ulceration. In 40 patients, proximal gastric vagotomy was combined with gastrojejunostomy, pyloroplasty, or pyloric dilatation for obstructing ulcers. There was a 15% incidence of reoperation in the gastrojejunostomy group. All nine patients who had proximal gastric vagotomy for active or recent bleeding ulcers were dismissed from the hospital without further hemorrhage, and only one developed a recurrent ulcer. It is concluded that proximal gastric vagotomy remains an acceptable operation for chronic duodenal and pyloric ulcers, but its efficacy in gastric ulcers is unproved.
Insights
Proximal gastric vagotomy is effective for chronic duodenal and pyloric ulcers, with a 7% recurrence rate. Its use for gastric ulcers requires further study due to unproven efficacy.
Area of Science:
- Gastroenterology
- Surgical Procedures
- Peptic Ulcer Disease
Background:
- Proximal gastric vagotomy (PGV) is a surgical technique aimed at reducing gastric acid secretion.
- Its effectiveness and complication rates for various peptic ulcer conditions have been evaluated over time.
Purpose of the Study:
- To report the Mayo Clinic's experience with proximal gastric vagotomy (PGV) between 1973 and 1980.
- To assess the recurrence and reoperation rates associated with PGV for different types of ulcers.
Main Methods:
- Retrospective analysis of 298 patients undergoing PGV for chronic duodenal, pyloric channel, or prepyloric ulcers.
- Evaluation of outcomes in patients with gastric ulcers, obstructing ulcers, and bleeding ulcers treated with PGV.
Main Results:
- A 7% recurrence rate was observed in patients with chronic duodenal, pyloric channel, or prepyloric ulcers after PGV.
- Three recurrences occurred in six patients with gastric ulcers, indicating limited efficacy.
- The gastrojejunostomy subgroup experienced a 15% reoperation rate for obstructing ulcers.
Conclusions:
- Proximal gastric vagotomy (PGV) is an acceptable surgical option for chronic duodenal and pyloric ulcers.
- The efficacy of PGV for gastric ulcers remains unproved and warrants further investigation.
