Background: As a minimally invasive treatment, ethanol sclerotherapy has been used for large symptomatic hepatic cysts, but there are not many long-term reports on treatment outcomes and safety.
Purpose: To evaluate the long-term outcomes of percutaneous ethanol sclerotherapy in patients with large symptomatic hepatic cysts.
Material and Methods: This study included 43 symptomatic, enlarging hepatic cysts in 42 patients who had undergone ethanol sclerotherapy from 2003 to 2013 and were followed up for >1 year. The treatment outcomes were evaluated in terms of the reduction of cyst size and resolution of symptoms. The patients were followed up for a mean period of 33 months with either ultrasound or computed tomography examination.
Results: Thirty-nine hepatic cysts (91%) were successfully treated with ethanol sclerotherapy, showing resolution of symptoms and remarkable reduction in cyst volume. Eight hepatic cysts (19%) disappeared completely, and 31 hepatic cysts (72%) decreased in size during the follow-up period. The mean diameter of the cysts decreased from 12.54.4cm to 3.8 +/- 3.4cm during follow-up. There were no immediate serious complications related to the procedure. There were four cases (9%) of treatment failure requiring subsequent surgical procedures.
Conclusion: Percutaneous ethanol sclerotherapy can be considered as an effective first-line treatment for large symptomatic hepatic cysts.
