Background
Simple liver cysts (LCs) represent the most common benign liver disease, with a prevalence of 3–5 %. Laparoscopic fenestration is considered the best treatment for symptomatic LCs, but few studies have analyzed the rate or type of recurrence during a long-term follow-up period (>5 years).
Methods
Between January 2000 and December 2010, 47 patients underwent laparoscopic fenestration for simple LCs. The indications were symptoms for 42 patients and an uncertain diagnosis for five patients. The follow-up assessment consisted of regular patient evaluations, with results of laboratory data and liver ultrasound.
Results
Conversion to laparotomy was not necessary in any case. The postoperative mortality and morbidity rates were nil. The mean follow-up period was 67 months (range 12–142 months), and 26 patients (55.3 %) had a follow-up period longer than 5 years. During the follow-up period, 40 patients (85.1 %) did not present with any type of recurrence. The overall recurrence rate was 14.9 % (seven patients) based on five patients (10.6 %) with radiologic asymptomatic recurrences detected by ultrasound or computed tomography (CT) scan and two patients (4.3 %) with clinicoradiologic symptomatic recurrences. Both symptomatic recurrences involved LCs located in the right posterior segments.
Conclusions
Laparoscopic fenestration provided complete relief of symptoms for about 95 % of patients with simple LCs. Recurrence after surgery was experienced by 14.9 % of the patients, but only in 4.3 % (two patients) was this recurrence symptomatic requiring a second treatment. The site of recurrence was more frequently in the right posterior segments. Laparoscopic fenestration of symptomatic LCs can be considered a safe and effective procedure that can yield good long-term results.
