Ultrasonic cavitation and decasan irrigation for residual cavity management in liver cystic echinococcosis: a retrospective comparative study from an endemic region.

Most often, Echinococcus parasitizes in the liver, causing the need for surgical treatment, the results of which currently do not meet expert expectations due to the high frequency of postoperative complications and the risk of relapse. The aim of the study is to improve the results of surgical treatment of liver echinococcosis by improving the tactical aspects of treatment and elimination of the residual cavity after echinococcectomy to prevent the development of purulent-septic complications. The object of the study was 442 patients with liver echinococcosis treated in the abdominal surgery of the Khorezm Regional Multidisciplinary Medical Center for the period from 2010 to 2023. To achieve the research goal and address the objectives, the following methods were used: general clinical, biochemical, instrumental and statistical methods. When determining the tactics and volume of surgical intervention, we recommend using the proposed method for treating the residual cavity using ultrasonic cavitation and a 0.02% Decasan solution, which minimized the development of purulent-septic complications in the immediate and long-term period after surgery. The new approach significantly reduced postoperative drainage needs (63.8% vs 36.6%, P < 0.001), complications (12.5% vs 5.4%, P < 0.001), and increased uncomplicated recovery (93.1% vs 80.0%). Drainage duration decreased from 11.3% to 3.5% in the long-term follow-up.
