Surgical strategy for cystic diseases of the liver in a western hepatobiliary center.

The aim of this study was to define the indications and evaluate the results of various management options in patients with cystic liver disease. Between 1992 and 1999 we managed 60 consecutive patients with cystic liver disease. Diagnoses included a simple cyst (solitary 12, multiple 10), adult polycystic liver disease (APLD 17), Caroli's disease (8), hydatid cysts (4), and neoplastic cysts (9). Half of the patients with simple cysts had mild or no symptoms and required no treatment. Percutaneous drainage in eight patients (simple cyst 4, APLD 4) was followed by symptomatic recurrence in three. Laparoscopic deroofing in three patients (multiple simple cysts 2, APLD 1) was followed by symptomatic enlargement of the remaining cysts that required further intervention (laparoscopic deroofing 2, transplantation 1). Laparoscopic hepatectomy was successful in three patients with solitary simple cysts. Of 18 patients who underwent open hepatic resection (neoplastic 8, Caroli's 4, simple cysts 3, hydatid cysts 2, APLD 1), 2 patients with Caroli's disease required liver transplantation for disease progression. Nine patients (Caroli's 5, APLD 4) underwent liver transplantation, and three had a concomitant renal transplant. Seven patients developed complications, and three died (5%). Cholangiocarcinoma developed in three patients with bilateral Caroli's disease, and all died. Radiologic treatment has a limited role in the management of patients with simple cysts or APLD. Laparoscopic deroofing of simple cysts may have to be repeated, whereas resection minimizes cyst recurrence. Unilobar Caroli's disease may be resected, whereas bilateral disease requires early liver transplantation owing to the high risk of malignancy. Transplantation is a reserved option in patients with extensive APLD.
