title: Functional modifications of endocrine pancreas after internal biliary fistula (experimental research).
abstract: The function of the B-insular system has been explored in dogs total internal biliary fistula (cholecysto-jejunostomy after closure of the common bile duct), an operation which causes an increase in number and total volume of pancreatic islets. Two groups of 10 animals each were either submitted to operation or used as controls. The endocrine function of the pancreas was explored 45-60 cays after surgery by assessing basal blood glucose and serum insulin. IVGTT and i.v. tolbutamide test were performed subsequently. The results indicate that in operated animals the ability to release insulin after stimulation is increased and that the control of basal hormone secretion is fully preserved.
