Abstract
Highly selective vagotomy (HSV) is now an accepted form of surgery for uncomplicated duodenal ulcer. Highly selective vagotomy and dilatation has been successfully used in some cases of pyloric stenosis, but many would regard severe pyloric stenosis as a contraindication to this procedure. Eleven patients with severe pyloric stenosis, measured objectively at operation, have been treated by HSV and dilatation of the stenosis and reviewed for periods of up to 3 years. The clinical results, immediate and long term, were good in all cases. Barium studies and histopathological findings were slower to return to normal. With intensive preoperative preparation to restore the tone of the dilated gastric muscle and gentle, controlled dilatation of the stricture, HSV in these patients should be as satisfactory as in those patients with uncomplicated duodenal ulcer.
