Objective: to perform a comparative analysis of postoperative complications and hospital stay terms of in-patients with malignant liver tumors after atypical liver resection and locoregional radiofrequency ablation of liver metastases.Material and methods. We analyzed the data of 295 patients with malignant liver tumors who had undergone surgical resection or radiofrequency ablation of tumor nodes.Results. We have systemized the direct results of locoregional radiofrequency ablation under sonographic control and liver resection. 45 patients (17.8 %) after liver resection and 1 (2.3 %) patient after radiofrequency ablation developed grade III–IV complications according to the Clavien-Dindo classification. The frequency of complications is statistically significantly lower after radiofrequency ablation. The duration of hospital stay after radiofrequency ablation therapy was 4.5 ± 2.5 days. After surgical liver resection, patients stayed in hospital for 10.7 ± 2.3 days.Conclusion. Locoregional therapy provides a statistically significant reduction in the incidence of complications and reduces the duration of hospital stay compared to liver surgery.
