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.

Radiofrequency Ablation Therapy

Heat transfer in radiofrequency ablation therapy of liver tumors is discussed. Temporal and spatial temperature changes around a single needle and multi-prong ablation probes in monopolar and bipolar configurations based on a two-dimensional finite elements method are presented. The temperature changes and related heat transfer in the tissue model help to visualize the shape and size of the ablated region. The visualization of the tissue temperatures and their progression could be useful in clinical applications of ablation therapy. Finite-element based numerical simulation, while providing useful visualizations of the temperature changes in and around the tumor, underestimates the lesion size. The perfusion in the tissue and the possible presence of large blood vessels in or near the ablated domain, and the temperature dependency of the thermal and electrical properties of the tissue are significant complicating factors in modeling and clinical applications.
