Background: This study aimed to evaluate the incidence of cystadenoma diagnosis in a series of laparoscopic treatments for nonparasitic liver cysts, as well as its management.
Methods: From 1996 to 2004, 26 patients with a nonparasitic cyst of the liver were selected for laparoscopic liver surgery. Solitary nonparasitic liver cysts were, whenever feasible, completely enucleated.
Results: In four patients, the histopathologic examination showed a cystadenoma. Three patients with 13, 9, and 12-cm cysts, respectively, had undergone complete enucleation of the lesion, with no evidence of recurrence in the follow-up visit. One patient with multicystic liver experienced a recurrence and required an open hepatic resection.
Conclusions: When a complete laparoscopic enucleation of the cyst can be ensured, a strict follow-up assessment should be considered as the definitive treatment, with surgical intervention demanded only in the case of recurrence or high suspicion for malignancy.
