Background: Inoperable hepatocellular carcinoma (HCC) can be treated with laparoscopic radiofrequency ablation (LRFA), which is generally a more accurate and accessible procedure than percutaneous RFA (PRFA). However, few studies have compared survival outcomes between LRFA and PRFA in patients with HCC.
Aims: This study aimed to compare the efficacy of LRFA and PRFA for HCC treatment.
Methods: Patients who underwent PRFA or LRFA as an initial treatment modality between April 2005 and April 2016 were enrolled in this study. The overall and recurrence-free survival rates were examined for each patient. Additionally, propensity score matching was performed for both groups.
Results: The baseline characteristics of patients in the PRFA and LRFA groups showed several minor differences. Multivariate analysis showed that the RFA method was not a critical determinant of recurrence-free or overall survival (p = 0.069 and p = 0.406). Among patients who underwent RFA as the initial treatment modality, there was no significant effect between either RFA procedures on survival. After propensity score matching, univariate analysis showed a significant difference in overall survival between PRFA and LRFA (p = 0.031). Multivariate analysis showed that LRFA is a strong factor that contributed to an improved overall survival in HCC patients (hazard ratio 0.108, p = 0.040). Furthermore, our data showed that LRFA was able to limit multiple intrahepatic recurrences, as well as prevent marginal recurrence.
Conclusions: LRFA appears to be superior to PRFA in terms of survival. LRFA may help reduce mortality in HCC patients.

Background: pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation (PAF) improves health-related quality of life (QoL). This study compares QoL improvement after radiofrequency ablation (RF) and cryoballoon ablation (cryo) and assesses additional ablations' role in QoL improvement.
Methods: we evaluated the QoL of consecutive patients with first-time RF and cryo for PAF between January 2017 and June 2019.

Background: Both radiofrequency ablation (RFA) and microwave ablation (MWA) are commonly used non-surgical treatment methods for lung cancer/lung metastases (LC/LM). However, there is still debate over which one is superior. The meta-analysis was conducted to evaluate the effectiveness and safety between the two groups.

This is an annual report indicating the number and early clinical results of annual vascular treatment performed by vascular surgeons in Japan in 2018, as analyzed by database management committee (DBC) members of the Japanese Society for Vascular Surgery (JSVS). To survey the current status of vascular treatments performed by vascular surgeons in Japan, the DBC members of the JSVS analyzed the vascular treatment data provided by the National Clinical Database (NCD), including the number of treatments and early results such as operative and hospital mortality. In total, 143,745 vascular treatments were registered by 1,090 institutions in 2018.

Article Synopsis
- The study investigates the effectiveness and safety of minimally invasive thermal ablation techniques (microwave ablation and radiofrequency ablation) compared to traditional open surgery for treating benign thyroid nodules.
- The research included 160 patients treated at a hospital between 2020 and 2023, with a subsequent propensity score matching process to create three comparable groups for analysis.
- Findings indicate that both microwave and radiofrequency ablation led to less blood loss, shorter surgery times, reduced hospital stays, lower pain levels, fewer complications, and higher patient satisfaction than open surgery.
