A case of an anomalous duodenum, pancreas and biliary tract, with gallstone perforation

A case of an elongated, anomalous duodenum with intestinal rotation, annular pancreas and disease of the biliary tract with acute jaundice caused by gallstone perforation is presented. The ERCP (endoscopic retrograde cholangiopancreatography) was of great value in the preoperative investigations. Surgical relief of the obstruction of the biliary duct made the patient free of symptoms.
