To evaluate the safety and efficacy of a new internal cold circulation bipolar radiofrequency compared with Habib-4X bipolar radiofrequency device in the resection of liver tumors.
A total of 85 patients with hepatocellular carcinoma who received radiofrequency-assisted liver resection from February 2017 to January 2020 were retrospectively enrolled in our study, in which 45 patients received the new internal cold circulation bipolar radiofrequency (New-RF) and 40 patients received Habib-4X bipolar radiofrequency (Habib-4X). Primary outcome measures were the speed of liver transection, the width of coagulation tissue, hemorrhage volume, blood transfusion rate, and operation time.
The baseline characteristics of patients in the New-RF and Habib-4X groups had no significant difference ( > 0.05). Compared to Habib-4X, the New-RF had a faster average speed of liver transection (4.81 ± 1.20 cm/min vs 3.64 ± 1.08 cm/min, < 0.001), a narrower width of coagulation tissue (1.42 ± 0.23 cm vs 1.81 ± 0.20 cm, < 0.001), a less operation time (55.04 ± 16.12 min vs 64.02 ± 15.09 min, = 0.010), a lower rate of needle path bleeding (13.3% vs 35.0%, = 0.019), and a lower carbonization rate of electrode needle (22.2% vs 77.8%, < 0.001). Hemorrhage during the transection (85.0 ml vs 105.0 ml, = 0.438) and hemorrhage per square centimeter (3.28 ± 0.86 ml/cm vs 3.60 ± 1.12 ml/cm, = 0.141) in the New-RF group were smaller than those in Habib-4X group with no significant difference.
The new internal cold circulation bipolar radiofrequency was a safe and efficacious auxiliary device for liver resection with a faster speed of resection, lower carbonization rate of electrode needle, and more precise range of coagulation.
评估新型内置冷循环双极射频与 Habib-4X 双极射频设备在肝肿瘤切除术中的安全性和有效性。
回顾性分析 2017 年 2 月至 2020 年 1 月接受射频辅助肝切除术的 85 例肝细胞癌患者的临床资料，其中 45 例行新型内置冷循环双极射频（New-RF）治疗，40 例行 Habib-4X 双极射频（Habib-4X）治疗。主要观察指标为肝切除速度、凝固组织宽度、出血量、输血率和手术时间。
New-RF 组和 Habib-4X 组患者的基线特征无显著差异（ > 0.05）。与 Habib-4X 相比，New-RF 的肝切除平均速度更快（4.81 ± 1.20 cm/min 比 3.64 ± 1.08 cm/min， < 0.001），凝固组织宽度更窄（1.42 ± 0.23 cm 比 1.81 ± 0.20 cm， < 0.001），手术时间更短（55.04 ± 16.12 min 比 64.02 ± 15.09 min， = 0.010），针道出血率更低（13.3%比 35.0%， = 0.019），电极针碳化率更低（22.2%比 77.8%， < 0.001）。New-RF 组肝切除时出血量（85.0 ml 比 105.0 ml， = 0.438）和每平方厘米出血量（3.28 ± 0.86 ml/cm 比 3.60 ± 1.12 ml/cm， = 0.141）虽较小，但差异无统计学意义。
新型内置冷循环双极射频是一种安全有效的肝切除术辅助设备，具有更快的切除速度、更低的电极针碳化率和更精确的凝固范围。
