Common bile duct obstruction caused by the hydatid daughter cysts

Echinococcosis is a human parasitary disease. In 2002, 29 new cases of liver echinococcosis were recorded in Croatia. Liver is the most common site of hydatid cysts. Nine patients with echinoccocal liver disease were operated in our department in 2002. Here we present a case where a patient with verified hydatid cyst in the left liver lobe developed high fever, jaundice, nausea, vomiting and pain in the upper abdomen. The symptoms were initially ascribed to the acute cholangitis. After unsuccessful antibiotic treatment, computerized tomography and endoscopic retrograde cholangiopancreatography (ERCP) were performed, demonstrating daughter cysts in the common bile duct. During ERCP, papilotomy was made and daughter cysts were extracted. Hydatid cyst was surgically removed, and a communication between the cyst and left hepatic duct was noted during surgery. Pericystectomy, choledochotomy, removal of remaining daughter cysts from the common bile duct, and sutures of left hepatic duct were performed. The patient recovered fully after the surgery. One of the possible complications of the liver hydatid cysts is the communication between cyst and the biliary tree. Such communications are usually asymptomatic, but symptoms can also mimic acute cholangitis and jaundice, which may lead to the misdiagnosis of the patient's condition.
