Aims:
Hepatic cysts have a prevalence of 2.5-7% and most of them are asymptomatic. However, large cysts may cause complaints; in such cases an appropriate treatment is necessary (open surgery, laparoscopic deroofing, removal of cystic fluid and injection of a sclerosing agent. The aim of this study was to assess the efficacy and safety of a single session technique with polidocanol in the therapy of symptomatic non parasitic hepatic cysts. MATERIAL AND METHODS. The study included 13 patients with symptomatic liver cysts (range 4-10 cm). All patients underwent percutaneous aspiration of the liver cyst under ultrasound guidance followed by instillation of polidocanol (3%, 4-10 ml). The patients were followed up at 1, 3 and 12 months. The disappearance of the cyst or reduction in volume more than 90% was considered successful. If the fluid was accumulated at 1month the procedure was repeated. If after the second injection the fluid accumulation was more than 50% of the initial volume the case was considered a failure and a laparoscopic deroofing was performed.
Results:
The procedure was successful in 10 patients, 9 after the first instillation and one after the second (76.9%). The mean initial volume of cysts was 228 ml, and the mean reduction in volume at 1, 3 and 12 months was 80.2%, 91.9% and 96.7%. The cyst resolution was gradual with clinically significant cyst reduction achievement within 1 year after therapy. In 3 patients the fluid reaccumulated at the same volume despite 2 instillations. Those 3 cases the procedure was considered failure and the patients were sent to surgery. In 2 patients (one successfully treated and one with treatment failure) bleeding during the first puncture and aspiration appeared and the therapy was postponed for 1 month. There were no significant adverse effects, and all the patients had relief of symptoms after therapy.
Conclusions:
This initial experience with percutaneous aspiration and polidocanol sclerosis of hepatic cysts demonstrated that the technique is efficient and safe.
