  • Title: Role of gastrin determinations in clinical surgery.
    Author: Stremple JF, Elliott DW.
    Journal: Am Surg; 1976 Feb; 42(2):102-7. PubMed ID: 1247250.
    Abstract:
    Patients with recurrent ulcer without retained antrum and with a complete vagotomy will have a low gastric acid output. Those with incomplete vagotomy and gastric resection will have a fasting and histamine-stimulated gastric acid output which are normal' this is as though they had no previous gastric operation. Both groups of patients will have a normal fasting and postprandial serum gastrin. Patients with recurrent ulcer associated with retained antrum will have a fasting and histamine-stimulated acid output above normal. In the latter, fasting serum gastrin will be increased twice normal but not as markedly increased as found in Zollinger-Ellison syndrome. Patients with retained antrum will have a marked postprandial increase in serum gastrin about two times the fasting level. Those patients with this syndrome will have markedly elevated fasting and histamine-stimulated gastric acid as well as marked hypergastrinemia.
