Biliary complications of large Echinococcus granulosus cysts: report of 2 cases and review of the literature.
Hydatid cysts are often incidentally found and remain clinically silent. However complications can occur. We present 2 patients who developed biliary complications due to a large hydatid cyst. In the first patient compression on the intrahepatic bile ducts and cystic duct by the cyst, caused cholangitis and cholecystitis. Moreover the cyst had ruptured into the right intrahepatic bile ducts. A sphincterotomy was performed with extraction of hydatid sand. A pericystectomy was necessary because of infectious deterioration of the patient. Albendazole was continued for 8 weeks after surgery. The second case presented with jaundice and weight-loss since 1 month. A large hydatid cyst caused compression on the bile duct bifurcation with proximal bile duct dilatation. A cystectomy was performed 2 weeks after albendazole therapy initiation, which was continued for 8 weeks after surgery. Follow-up of both surgical interventions was unremarkable. Although Echinococcus granulosus in not prevalent in Belgium, we must be aware of this pathology in patients coming from high endemic regions.
