[Surgery for Echinococcus cysts in the liver].

Hydatid disease is a parasitic infection caused by Echinococcus granulosus, and the most frequently affected organ is the liver. Diagnosis is usually based on radiological and serological findings. Even though percutaneous drainage and medical therapies are suggested for selected cases, for the most part surgery is required. The surgical strategy consists of killing the cyst, removing its contagious elements from the liver, obliterating the cystic cavity, and preventing recurrence and complications. A large spectrum of operations - from simple drainage to liver transplantation - has been proposed for reaching these objectives. Laparoscopic surgery is used increasingly for hydatid disease. This article reviews the current status of hydatid disease surgery, with special emphasis on liver cysts.
