Despite the progress made in the surgical treatment of liver echinococcosis, the problem of choosing the nature of the surgical intervention remains relevant. In contrast to the effectiveness and radicalness of extensive resection interventions for widespread liver echinococcosis, there are factors of possible complications and technical difficulties. The question of the effectiveness of a number of additional surgical technologies in performing extensive liver resections for parasitic pathology also remains debatable. The article presents the results of surgical treatment of 61 patients (23/37.7 % men, 38/62.6 % women) operated in the surgical department No2. M.A. Podgorbunsky (Kemerovo) in the period 2006 to 2022 due to liver echinococcosis. The criterion for inclusion in the study was the performed extensive liver resection in the amount of lobar resection or more. Based on statistical calculations, an analysis was made of the effectiveness of the applied surgical technologies, as well as the immediate and long-term results of the treatment of patients. The effectiveness of both the applied surgical technologies and extensive resection interventions in general in the treatment of widespread liver echinococcosis has been established.
