Hepatic Cysts

Treatment of hepatic cysts should be considered only for those patients who are symptomatic. For simple cysts, percutaneous aspiration invariably leads to recurrence; laparoscopic deroofing is usually curative. Open deroofing (fenestration) should be reserved for cysts inaccessible by laparoscopy. Percutaneous instillation of sclerosing agents (ethanol, iophendylate, minocycline) into nonbiliary and nonparasitic cysts is an alternative therapeutic option in certain cases. Due to increased morbidity, hepatic resection should be reserved for polycystic liver disease, diffuse hepatic involvement, or recurrence after a deroofing procedure. Patients with congenital fibropolycystic disorders (eg, congenital hepatic fibrosis) with evidence of hepatic decompensation, should be considered for liver transplantation. For hepatic hydatid cysts, simple cystectomy or the PAIR (puncture, aspirate, inject, and reaspirate) technique with albendazole treatment have been shown to be equally successful. In the case of alveolar echinococcosis, hepatic resection and liver transplantation are the only effective modalities for localized and extensive hepatic disease, respectively.
