We examined prospectively the criteria for medical management in 16 patients with Zollinger-Ellison syndrome who had had previous gastric surgery. Each patient received sufficient antisecretory medication to lower gastric acid output to less than 10 mEq/h during the last hour before the next dose of drug. The 7 patients with a vagotomy but no gastric resection were symptom-free and had no mucosal disease. Of 9 patients with a partial gastrectomy, 7 had mucosal disease, with or without symptoms, and 6 of the 7 patients had acid outputs of 5-10 mEq/h. In these patients, antisecretory medication was increased to reduce output to less than 5 mEq/h and symptoms and mucosal abnormalities resolved in each patient. Patients with Zollinger-Ellison syndrome and a vagotomy can be treated safely by reducing acid secretion to less than 10 mEq/h, but in patients with a partial gastrectomy, acid secretion must be reduced to less than 5 mEq/h, and adequacy of therapy must be checked further by endoscopy.
