A 56-year-old woman was diagnosed with a giant hepatic cyst in the right liver 6 months earlier andfollowed up. After upper abdominal pain had been present for a month, the patient was hospitalized fortreatment.Blood examinations showed no evidence of cystic infection.Abdominal echography,CT,and MRIrevealed a giant simple hepatic cyst 16 cm in diameter in the right liver.Laparoscopic fenestration surgery wasperformed. Although ablation of the cystic cavity with an argon beam coagulator was attempted to preventrecurrence, the area was so wide that there were some parts that could not be ablated sufficiently bylaparoscopic operation. Thus, the procedure was stopped and the cystic cavity was covered by the greateromentum.No complications occurred during or after surgery and there has been no recurrence as determinedby CT 6 months later. In summary, we experienced a case of giant hepatic cyst in which laparoscopicfenestration surgery and omental covering surgery were effective. Shinshu Med J 58 : 163―167, 2010
