Abstract

Until recently in this unit gastroenterostomy was the operation of choice for patients with duodenal ulcer whose maximal acid output (MAO) is less than 30 mmol/hr. Ulceration (jejunal) has recurred in only 2.1%. Unlike partial gastrectomy, which has a peak incidence of ulcer recurrence in the first two years, the incidence of ulcer recurrence remains constant throughout the years after gastroenterostomy. In looking for the explanation of this low recurrence rate we have studied the effect of the operation upon serum gastrin responses to standardized test meals 3 weeks and 26 weeks after operation in 9 patients. Nine normal subjects acted as controls. Six months after operation the responses were significantly lowered, a fall in the serum levels of gastrin at 30, 45, 60, and 90 min after meals suggesting that gastroenterostomy reduces both the gastric and intestinal phases of acid secretion. The mean integrated gastrin response (IGR) throughout the postprandial 90 min is also significantly lower 6 months after surgery. The overall mean reduction was 31.1%.
