    Abstract:
    In the present study we explored whether the presence or absence of symptoms could provide a reliable way of assessing the adequacy of control of gastric secretion in patients with Zollinger-Ellison syndrome who were treated medically. Over a 5-yr period, 26 Zollinger-Ellison syndrome patients were entered into a prospective study which examined the presence or absence of symptoms that are associated with gastric hypersecretion, the presence of absence of upper gastrointestinal pathology, and the degree of control of gastric acid secretion. During their last admission, 15 of the 26 patients (58%) were symptomatic, but post-drug gastric acid secretion for the 2 h before the next dose of medication was not significantly different from that in asymptomatic patients. This lack of correlation between the presence or absence of symptoms and post-drug gastric acid secretion was evident for the group as a whole, as well as for 8 to 12 patients who underwent multiple admissions. Of 23 patients who underwent upper gastrointestinal endoscopy of x-ray, or both, on their last admission, 12 had pathology. Post-drug gastric acid secretion was less in patients without pathology than in those with pathology. Furthermore, in patients in whom post-drug gastric acid secretion was less than or equal to 10 mEq/h, the criterion of acceptable control used in this study, pathology did not occur. These findings demonstrate that the presence or absence of symptoms cannot be used to assess the adequacy of medical control of gastric acid secretion in patients with Zollinger-Ellison syndrome. In our opinion, maintenance of post-drug gastric acid secretion less than or equal to 10 mEq/h for the 2 h before the next dose of medication is an acceptable criterion for long-term control of gastric secretion in patients with Zollinger-Ellison syndrome.
