A case of groove pancreatitis with portal venous obstruction treated with distal gastrectomy with Roux-en-Y reconstruction

Abstract

A 39-year-old man with abdominal pain and vomiting was referred to our hospital. He had consumed alcohol (about 75 g per day) for 18 years. Upper gastrointestinal series revealed a circumferential stricture of the second portion of the duodenum. Abdominal CT and MRI showed a cystic mass (20×15 mm) at the groove area between the duodenum and choledochus, and portal venous obstruction accompanied with the growth of collateral vessels. We suspected groove pancreatitis rather than pancreatic cancer. His symptoms subsided with conservative treatment, but he was readmitted for vomiting. The size of the cystic mass increased. We adopted a distal gastrectomy with Roux-en-Y jejunal reconstruction. The postoperative course was uneventful. The cystic mass disappeared with no recurrences for 2 years after surgery. © 2011 The Japanese Society of Gastroenterological Surgery.
