Acute cholangitis caused by intra-biliary rupture of pancreatic hydatid cyst.

A case of intra-biliary rupture of pancreatic hydatid cyst is presented. The site of the cyst in the pancreatic head, cholangitis, the advanced age of patient, previous history of cholecystectomy, liver hydatidosis and gastrectomy for ulcer disease, led to diagnostic and therapeutic difficulties. As in some cases of intra-biliary rupture of the liver hydatid cyst, surgical treatment of this pancreatic hydatid cyst included evacuation of cystic contents through choledocotomy and biliary-enteric anastomosis with uneventful postoperative course.
