To evaluate the clinical efficacy of laparoscopic fenestration drainage combined with dehydrated alcohol perfusion and bipolar electro-cauterization of cyst wall in treating hepatic cyst.

Clinical data of 15 patients with hepatic cyst undergoing laparoscopic fenestration drainage combined with dehydrated alcohol perfusion and bipolar electro-cauterization of cyst wall in the First People's Hospital of Foshan between January 2013 and December 2015 were retrospectively analyzed. Among them, 7 patients were male and 8 were female, aged 40-65 years with a median age of 51 years. The informed consents of all patients were obtained and the local ethical committee approval was received. All the patients received laparoscopic fenestration drainage, dehydrated alcohol perfusion and bipolar electro-cauterization of cyst wall. Intraoperative and postoperative physical conditions of the patients were observed.

The surgery was successfully completed in all patients. No conversion to open surgery occured. The median operating time was 60(50-75) min. The intraoperative hemorrhage volume was 30(15-50) ml. The volume of drainage cystic fluid was 1 450(1 000-2 000) ml. The postoperative time of removal of drainage tube was 3(2-4) d. The postoperative length of hospital stay was 4(3-5) d. Neither bile leakage nor hemorrhage complications occurred after surgery. No recurrence was observed in all patients by ultrasound, CT scan or MRI 1 year after surgery.

Laparoscopic fenestration drainage combined with dehydrated alcohol perfusion and bipolar electro-cauterization of cyst wall is a safe and effective way for treating hepatic cyst. It has the advantages of minimally invasion, low incidence of bile leakage and recurrence rate.
