[Neurohumoral regulation of gastric secretion in postvagotomy syndromes].

The secretion of hormones stimulating and inhibiting gastric secretory activity was studied in 85 patients with postvagotomy syndromes. The somatropin level was found to increase significantly in gastrostasis. The lower values of the blood insulin and C-peptide content in patients with recurrent ulcers was evidently associated either with insufficiency of the pancreatic insular apparatus or with partial vagal denervation, increased STH level, and plausible inhibiting effect of glucagon. Increased somatostatin secretion in the dumping syndrome, gastrostasis, and peptic ulcers may be due to the encountered hypergastrinemia.
