Effect of antrectomy on the nervous phase of gastric secretion in the dog.
A method is described for complete isolation of the stomach in the dog with vagal innervation intact. This involves esophagostomy, double mucosal closure of the pylorus and a Maydl gastric fistula combined with gastrojejunostomy. The latter is occluded during periods of study. In this preparation the responses to sham feeding and to insulin-induced hypoglycemia were reduced approximately 10-fold, reiterating the significant synergistic effect of gastrin on vagal stimulation of the parietal cell mass. However, significant acid secretion could still be induced in this preparation by both sham feeding and insulin-induced hypoglycemia.
