This retrospective study aims at demonstrating the success rate, effectiveness, and advantages of alcohol as a scolicidal and sclerosing agent for the percutaneous treatment of liver hydatid cysts. A total of 554 liver hydatid cysts obtained from 347 patients admitted between January 2008 and February 2016 were retrospectively investigated. Of these, 435 (78.5%), 91 (16.4%), and 28 (5%) were classified as Gharbi type 1, 2, and 3, respectively. Type 1 and 2 cysts were treated using PAIR (puncture, aspiration, injection, respiration) and single puncture catheterization methods; type 3 lesions were treated using a modified catheterization technique. Alcohol was used as a scolicidal and sclerosing agent in all procedures. After excluding three lesions (0.5%) because of lack of parenchymal support during catheterization, 274 (49.7%), 250 (45.3%), and 27 (4.9%) of 551 lesions were treated with PAIR, single puncture catheterization, and modified catheterization techniques, respectively. Therefore, a 99.5% of technical success rate was obtained. Major complications in 2 patients (0.5%) and minor complications were observed in 36 patients (10.3%). Mean hospital stay was 1.55±2.3 days (range: 0-23 days). Patients were followed-up for mean 19.6 months (range: 6-83 months), during which recurrences were detected in 19 patients (5.4%). The use of alcohol as a scolicidal and sclerosing agent during the percutaneous treatment of liver hydatid cysts is associated with a high success rate and low rates of recurrence and complications, and should be considered an important alternative to surgical procedures.
