Abstract
The secretln and secretin-cecekin response curves after partial gastrectomy alone, or with truncal or selective ragotomy, are approximately the same whether with maximal or less than maximal secretory stimuli. There was no difference in response between truncal and selective vagotomy in patients with pyloroplasty. Pyloroplasty patients have a response to secretin which approximates normal control value, while that in the Billroth I patients is depressed. Diarrhea following vagotomy is not due to depressed pancreatic responsiveness to secretin and pancreozymin.
