Diagnosis and management against the complications of human cystic echinococcosis.

Cystic echinococcosis (CE) (hydatidosis, hydatid disease) is a zoonosis caused by the larval stage of Echinococcus granulosus, typically affecting the liver. Hepatic cystic echinococcosis (HCE) is often asymptomatic, and symptoms occur largely when complications develop. Up to one-third of HCE can be shown their complications such as rupture of the cyst, secondary infection, and anaphylactic reaction. Clinically, patients present with pain, obstructive jaundice, cholangitis, anaphylactic reaction, and shock. Early diagnosis and treatment of complications of CE must be very important, since mortality is high when obstruction of the biliary ducts occurs, leading to ascending cholangitis and septicemia, anaphylactic shock, or even life-threatening conditions.
