PURELY CYSTIC HYDATID-DISEASE OF THE LIVER - TREATMENT WITH PERCUTANEOUS ASPIRATION AND INJECTION OF HYPERTONIC SALINE

Percutaneous aspiration of purely cystic liver lesions was performed in 15 patients aged 11-56 years. After aspiration under guidance with computed tomography (CT) in 12 patients, a membrane that is diagnostic for hydatid disease was visible in the lumen of the cyst on CT scans. Hypertonic saline was injected in the cystic cavities of these patients as a scolecidal agent. No major complications occurred during or after the procedures. In the follow-up period of 6-16 months, control CT and ultra-sound scans revealed a progressive decrease in the size of the lesions and no evidence of peritoneal seeding. It is concluded that percutaneous aspiration and hypertonic saline injection for purely cystic hydatid disease of the liver seem to be an effective form of treatment and may eventually prove to be an alternative to surgical intervention.
