Acute pancreatitis complicating intrabiliary rupture of liver hydatid cyst.

Acute pancreatitis is a rare complication of hydatidosis, and the successful use of endoscopic sphincterotomy in the treatment of pancreatitis complicating ruptured hydatid cyst has been very rarely reported.We report here a case of a 50-year-old man, known to have hydatid cyst of the liver, who presented with upper abdominal pain. Amylase and lipase were elevated and echinococcus serology was positive. Abdominal CT scan showed a cystic lesion in the right lobe of the liver and a diffusely swollen pancreas with indurations around it. At endoscopic retrograde cholangiopancreatography (ERCP) the common bile duct was dilated. A sphincterotomy was performed and a mucoid structure was extracted, after which the patient made an uneventful recovery.
