Endoscopic retrograde cholangiopancreatography in the diagnosis and management of nonalcoholic pancreatitis

Abstract

Twenty-eight consecutive patients with idiopathic pancreatitis were studied. Endoscopic retrograde cholangiopancreatography was diagnostic in 21 of 28, while an operation was diagnostic in four of the remaining seven patients. Fifteen of 25 patients had operable disease of the gallbladder, common bile duct, ampulla of Vater or pancreatic duct. Of ten patients who had an operation on the pancreas or biliary tract, or both, for painful attacks of pancreatitis, none had a recurrence in a seven month to three year follow-up study. Two patients had reconstruction of the pancreatic duct for chronic painless steatorrhea, one of whom had marked clinical improvement. Ten of 25 patients had normal biliary tracts with normal or minimally abnormal pancreatic ducts and were treated medically. Visualization of biliary and pancreatic ducts should be attempted by endoscopic retrograde cholangiopancreatography in patients with pancreatitis of unknown cause. Operable lesions were found in 15 of 25 patients, and the postoperative results were excellent.
