Satellite cysts and biliary fistulas in hydatid liver disease. A retrospective study of 17 liver resections.

In Switzerland, the preferred mode of treatment for hydatid liver disease caused by Echinococcus granulosus is surgery, giving us the opportunity for a retrospective histopathologic study of 17 consecutive liver resections. We focused on the occurrence of satellite cysts and of biliary fistulas and their effects on bile ducts. Of 17 patients, 6 (35%) had one or more satellite cysts, to be distinguished from internal daughter cysts.
