Parasitologic findings in percutaneous drainage of human hydatid liver cysts.
Percutaneous drainage under ultrasonographic guidance was carried out on 12 patients with liver cysts and 1 with an abdominal cyst. In 8 the cyst was proved to be of hydatid origin by means of direct detection of parasites in the aspirated fluid. In these individuals a 95% ethanol solution was subsequently introduced into the cystic cavity and slowly removed over 30 min. Direct observation, staining for viability assessment, and in vitro isolation attempts were done both before and after the injection of the alcoholic solution, thus making possible the immediate evaluation of the protoscolicidal properties of the solution used. The procedure seems to be therapeutically successful, safe, and feasible.
