Hepatic resection for cystic lesions of the liver.

Objective: The purpose of this study was to report the authors' experience with hepatic resection for cystic lesions of the liver.
Summary Background Data: Past experience with aspiration, sclerosing therapy, internal drainage, fenestration, and marsupialization are of limited value. Hepatic resection has evolved into a safe operation over the last two decades.
Methods: A retrospective study of 44 patients with various cystic lesions of the liver (polycystic disease, 2; solitary or multiple congenital cysts, 19; biliary cystadenoma, 6; cystadenocarcinoma, 3; squamous cell carcinoma, 3; Caroli's disease, 5; and hydatid cyst, 6) was performed.
Results: After 7 trisegmentectomies, 24 lobectomies, 6 left lateral segmentectomies, and 7 nonanatomical hepatic resections, only 1 operative death occurred in a Jehovah's Witness. Symptomatic relief was complete and permanent in all of the patients with benign congenital or parasitic hepatic cysts, except for the two patients with polycystic disease of the liver. One of the 3 patients with adenocarcinoma and 3 patients with squamous cell carcinoma of the cyst wall died of tumor recurrence between 3 and 14 months after hepatic resection.
Conclusions: Hepatic resection is safe and effective for cystic lesions of the liver. Symptomatic relief is complete and permanent after hepatic resection, except in cases of diffuse polycystic disease of the liver. Liver transplantation should be considered for diffuse polycystic disease of the liver when the symptoms are extremely severe.
