five years' experience with proximal gastric (highly selective) vagotomy.

In the five-year period 1972 to 1976 the author's preferred treatment for patients with chronic duodenal or prepyloric peptic ulcer requiring surgery was proximal gastric vagotomy. In spite of this preference, only two-thirds of such patients were so treated. Most patients with bleeding and stenosis were treated by bilateral truncal vagotomy and drainage, and a few by Pólya gastrectomy. Proximal gastric vagotomy proved to be a safe elective operation without mortality and with a proven ulcer recurrence rate so far of 6%. Compared with those who had bilateral truncal vagotomy and drainage, the proximal gastric vagotomy patients complained less often of diarrhoea but more often of weight loss and reflux. Two patients have had persistent postprandial non-peptic pain, thought possibly due to upper gastric ischaemia.
