The authors have examinated 35 patients 4 - 5 years after a previous episode of acute oedematous biliary pancreatitis. 20 patients had been cholecystectomized while 15 had not been operated. The patients of the first group didn’t show any impairment of the endocrine or exocrine pancreatic function while the patients who were not cholecystectomized in 4 cases on 15 showed an impairment of the exocrine pancreatic function valued with the elastase-1 test in the stools. In 2 patients there was also a slight impairment of the glucose metabolism. The authors suppose that the persistance of a biliary disease can affect the pancreatic function.
