Pancreaticobiliary maljunction and pancreas divisum accompanied with intestinal malrotation: a case report

Abstract

BackgroundPancreaticobiliary maljunction is a congenital anatomical abnorma l junction of the pancreatic duct and bile duct into a common channel outside the duodenal wall. Pancreas divisum is also a congenital anatomical abnormality characterized by unfused pancreatic ducts. Intestinal malrotation is caused by the failure of bowel rotation and fixation. We reported an optimal surgical intervention for the rare case of pancreaticobiliary maljunction and pancreas divisum accompanied intestinal malrotation.Case presentationA 2-year-old female presented with fever and jaundice. Abdominal ultrasound showed dilated common bile duct and intrahepatic bile ducts; MRCP showed pancreaticobiliary maljunction, pancreas divisum, and dilated biliary system; Abdominal contrast-enhanced CT showed a reversed relationship between the superior mesenteric artery and the superior mesenteric vein. An operation of laparoscopic resection of the extrahepatic bile duct, Roux-en-Y hepaticojejunostomy, and Ladd’s procedure was performed after the inflammation of the biliary system was treated. The post-operative follow-up period was uneventful.ConclusionsThe management of pancreas divisum can be conservative. We present an optimal pattern of Roux-en-Y hepaticojejunostomy to deal with pancreaticobiliary maljunction associated with intestinal malrotation.
