Total pancreas divisum caused by ventral pancreas malrotation showing biliary pancreatitis.

A 52-year-old man was admitted to our hospital complaining of abdominal pain. A blood test showed high serum levels of biliary enzymes and amylase. Surprisingly, a computed tomography scan revealed complete separation of the ventral and dorsal pancreas and swelling of the ventral pancreas with choledocholithiasis. Surgical cholecystectomy was performed to remove the bile duct stones after endoscopic removal was unsuccessful. The complete separation of the pancreatic parenchyma caused by ventral pancreas malrotation seen in this case is extremely rare, and may provide important information regarding embryologic development, deformity, and malfunction of the pancreas.
