Abstract
Eight patients with 15 symptomatic nonncoplastic congenital hepatic cysts underwent ultrasound-guided percutaneous aspiration and temporary injection of 99% ethanol into the cyst. All cysts were treated at least twice at the same sitting. The volume of alcohol injected varied from 20 to 100 ml, depending on the size of the cyst. A cure was usually achieved with one alcohol sclerotherapy treatment. Only minor side effects such as transient pain and temperature elevation occurred. No recurrences were found during a follow-up period of 12 to 32 months. The results indicate that aspiration and alcohol sclerotherapy is a feasible alternative to surgical intervention in patients with symptomatic nonneoplastic congenital hepatic cysts. We recommend it as the treatment of choice in cases with high surgical risk or polycystic liver disease.
