[Study of the behavior of gastric secretory function after proximal selective vagotomy for duodenal ulcer]

In 60 patients with duodenal ulcer subjected to S.P.V. operation, a study of gastric secretion (quantity of gastric juice, B.A.O., M.A.O., P.A.O., Hollander's test) and of gastrinemia before the operation, after one month and after one year was made. The results supplied by this study are: a marked reduction (over 50%) in the basal values and those after stimulation of the quantity of gastric juice and of acid secretion, with persistence of such reductions a long time after the operation. The finding of three cases with positive Hollander's test, which was negativised after administration of a beta-blocking drug, induced the Authors to a critical revision of the literature on the relations between sympathetic and parasympathetic innervation of the stomach in relation to gastric secretion.
