Laparoscopic Deroofing Combined with Omental Transposition Flap for Nonparasitic Giant Liver Cyst : A Case Report

Abstract

A 56-year-old woman was diagnosed with a giant hepatic cyst in the right liver 6 months earlier and followed up. After upper abdominal pain had been present for a month, the patient was hospitalized for treatment. Blood examinations showed no evidence of cystic infection. Abdominal echography, CT, and MRI revealed a giant simple hepatic cyst 16cm in diameter in the right liver. Laparoscopic fenestration surgery was performed. Although ablation of the cystic cavity with an argon beam coagulator was attempted to prevent recurrence, the area was so wide that there were some parts that could not be ablated sufficiently by laparoscopic operation. Thus, the procedure was stopped and the cystic cavity was covered by the greater omentum. No complications occurred during or after surgery and there has been no recurrence as determined by CT 6 months later. In summary, we experienced a case of giant hepatic cyst in which laparoscopic fenestration surgery and omental covering surgery were effective.
