Abstract
We report choledochocele accompanied by severe acute pancreatitis. A 70-year-old male was admitted to our hospital for upper abdominal pain. The patient was diagnosed as having severe acute pancreatitis, with a severity score of 6 according to the Japan scoring system. Intra-arterial injection of a protease inhibitor and antibiotic was carried out for partial necrosis of pancreas. He recovered gradually without complications. The patient had experienced acute pancreatitis several times in the past without cholelithiasis, hyperlipemia, or alcohol drinking. Endoscopic retrograde cholangiopancreatography was carried out to investigate the cause of the pancreatitis. Choledochocele was found, and endoscopic sphincterotomy (EST) was performed. The patient has experienced no pancreatitic symptoms, and no malignant change has been detected in the 4 years since EST.
