[Echinococcosis of the liver: evolution of surgical treatment].

OBJECTIVE To analyze the development of surgical approaches for hepatic echinococcosis. MATERIAL AND METHODS We have analyzed diagnosis and treatment of 349 patients with liver echinococcosis; 97 patients were treated at the Botkin Clinical Hospital for the period from 2009 to 2019 and 252 patients were treated in surgical hospitals of Moscow city for the period from 2014 to 2019. RESULTS General and specific postoperative complications, relapses and surgical approaches were assessed. The number of echinococcectomies performed in surgical hospitals of Moscow is 3 times higher compared to the Botkin Hospital. The number of liver resections is comparable in both groups. The number of pericystectomies is more than 2 times higher in the Botkin Hospital. PAIR technique was more common in surgical hospitals of Moscow. CONCLUSION Evolution of surgical treatment from open echinococcectomy to anatomical liver resections and subsequent pericystectomy with PAIR technique becomes another round of evolutionary spiral in the development of surgical treatment of liver echinococcosis.
