Laparoscopic fenestration in combination with ethanol sclerotherapy prevents a recurrence of symptomatic giant liver cyst.

Laparoscopic fenestration in combination with ethanol sclerotherapy of the cyst wall was performed in four patients with symptomatic giant solitary liver cyst. Two of these patients had recurrent liver cysts, which were resistant to simple laparoscopic fenestration. After the combination therapy, none of the cysts recurred during follow-up periods ranging from 11 to 33 months.
