Thirty-four patients (13 male and 21 female), ranging in age between 14 and 80 years, with 55 liver hydatid cysts underwent percutaneous treatment with albendazole prophylaxis. Cysts were treated with a one-stage procedure that consisted of puncture of the cysts under guidance with computed tomography, aspiration of fluid, injection of hypertonic saline solution as scolicidal agent and reaspiration. Follow-up examinations showed progressive reduction and solidification of the cysts. The mean reduction in volume was 72%. No mortality, abdominal dissemination, or tract seeding occurred. Minor complications were urticaria with pruritus in two patients. One patient had a subcapusular hematoma without problem. Hospitalization courses varied from ambulatory procedures to 15 days of in-patient, mean hospital stay was 1.82 days. The results of percutaneous liver hydatid cyst treatment, indicating that the procedure is efficient and safe and offers complete cure in selected patients with a short hospitalization and that this technique should be considered an alternative to surgery.
