[Effect of selective proximal vagotomy on pancreatic islet function in duodenal ulcer]

The tolerance to glucose and immunoreactive insulin blood level in duodenal ulcer cases before operation and following selective proximal vagotomy combined with stomach drainage and without the latter has been studied. These operations result in the normalization of the body tolerance to glucose disturbed in duodenal ulcer. The insular function of the pancreas does not get upset therewith.
