RECENT TREATMENT RESULTS OF LIVER ECHINOCOCCOSIS BY PAIR METHOD (PUNCTURE, ASPIRATION, INJECTION, REASPIRATION).

The development of new technologies in medicine lead to creating an optimal treatment methods of cystic liver echinococcosis, based on minimally invasive technologies, such as percutaneous puncture-aspiration echinococcectomy (PAIR) under ultrasound (US) guidance. Aim of this study is to analyze and evaluate the efficiency of PAIR treatment. The study material included a retrospective analysis of 33 patients who underwent PAIR from December 2017 to December 2019. Of them, 25 (75%) patients with primary CLE, 8 (24%) patients with recurrent cystic liver echinococcosis. Cystic liver echinococcosis was staged according to WHO classification by US images. All patients pre- and postoperatively received therapy with Albendazole. The mean duration of surgery was 41 (30-70) min. Hospital stay times were ranged from 2 and 16 days (mean 4,8 days) in all patients. The conversion to laparotomy during the procedure was not necessary. Operation was finished in 3 cases due to developing anaphylactic shock during operation. There was no fatal outcome in any cases. One patient developed bilio-cystic communication, resolved spontaneously without additional treatment. The use of minimally invasive PAIR intervention followed by Albendazole therapy has a positive effect on reducing the patient's hospital stay.
