Case report: laparoendoscopic single-site fenestration of giant hepatic cyst.

Laparoendoscopic single-site (LESS) surgery has developed as a new surgical modality producing increased cosmetic benefits over conventional endoscopic surgery. However, there are limited reports about LESS surgery in liver diseases. We reported a case of a giant hapatic cyst that was treated by LESS surgery. LESS fenestration was performed on a 60-year-old female. A 2.2-cm umbilical incision was made. Three laparoscopic trocars were individually inserted into the abdominal cavity via a single umbilical incision. Only straight laparoscopic instruments were applied throughout the procedures. Aspiration, dome resection, argon laser coagulation, drainage, and removal were performed by LESS surgery. One of the 5-mm trocars was replaced with a 12-mm trocar to retrieve the resected cyst wall. All of the procedures for liver fenestration were the same as conventional laparoscopy and were successfully performed without any difficulties. The patient had an uncomplicated postoperative course. The LESS surgery has been successfully applied to liver fenestration as an available alternative to conventional laparoscopic fenestration. This method is technically feasible and results in superior cosmesis.
