UNLABELLED: Serum gastrin changes before and after selective proximal vagotomy (SPV) were studied in relation to the gastric motility and the acid secretion clinically and experimentally and the effects of pyloroplasty were investigated.
RESULTS AND CONCLUSIONS: Experimental studies revealed that test meals provoked gastrin secretion to stimulate gastric motility. Periodical gastric acid secretions were observed during hunger period, along with elevated serum gastrin levels. After SPV, gastrin responses to the test meals were significantly increased so that the pyloric ring motility was disturbed. Clinical studies revealed that adrenaline infusion test provoked significant gastrin responses to secrete acid secretions in duodenal ulcer patients. After SPV, increased gastrin responses to adrenaline restored acid secretions as much as preoperative acid secretions responded to the adrenaline test. Pyloroplasty for the SPV inhibited the gastrin and acid secretions responded to the adrenaline test.
