Hepatic cysts treated with percutaneous ethanol sclerotherapy: time to extend the indications to haemorrhagic cysts and polycystic liver disease

摘要

Objectives To describe the long-term clinical and morphological outcome of symptomatic hepatic cysts treated with percutaneous ethanol sclerotherapy (PES). Methods From December 2003 to September 2011, all patients with hepatic cysts undergoing PES with a follow-up after 12 months were included. Evolution of the volume of the cysts and clinical and biological data were recorded. Features of the cyst were evaluated in each patient: simple, haemorrhagic or developed on underlying polycystic liver disease (PCLD).Results Fifty-eight cysts (median volume 666 mL) were treated in 57 patients (52 women, mean age 58 years (18-80)). Twenty-two patients (39 %) had simple hepatic cysts, 19 (33 %) had dominant cysts on PCLD and 20 had haemorrhagic cysts (34.5 %), including 4 with PCLD. Aftera mean 27.3 months of follow-up, the final median cystic volume was 13.5 mL (p<0.0001), and the median reduction in cyst volume was 94 % (58-100 %). Treatment was satisfactory in 95 % of the patients (54/57) (symptoms disappeared in 45/57 (79 %), decreased in 9/57 (16 %)). There was no clinical or morphological difference between patients with PCLD, haemorrhagic cysts or simple cysts.
