A case of combined bile duct resection with cholecystectomy for non-dilated pancreaticobiliary maljunction diagnosed as acute pancreatitis in a 16-year-old patient

Abstract

A 16-year-old-male was introduced to our hospital for the purpose of examining the etiology of pancreatitis. Abdominal and endscopic ultrasonography showed gallbladder wall thickness. Endoscopic retrograde cholangiopancreatography revealed pancreaticobiliary maljunction (PBM) without dilation. Biliary amylase level was high (302,300U/l). Gallstones, pancreatic tumors and autoimmune diseases were negative. Combined bile duct resection with cholecystectomy was performed for this PBM case, because pancreatitis was due to PBM. Histopathological examination of the resected specimens revealed no malignancy. The postoperative complications and recurrence of pancreatitis have not occurred. Combined bile duct resection with cholecystectomy may be effective surgical treatment for this PBM case.
