Abstract

Purpose

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.

Methods

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.

Results

The baseline characteristics of patients in the New-RF and Habib-4X groups had no significant difference (p > 0.05). Compared to Habib-4X, the New-RF had a faster average speed of liver transection (4.81 ± 1.20 cm²/min vs 3.64 ± 1.08 cm²/min, p < 0.001), a narrower width of coagulation tissue (1.42 ± 0.23 cm² vs 1.81 ± 0.20 cm², p < 0.001), a less operation time (55.04 ± 16.12 min vs 64.02 ± 15.09 min, p = 0.010), a lower rate of needle path bleeding (13.3% vs 35.0%, p = 0.019), and a lower carbonization rate of electrode needle (22.2% vs 77.8%, p < 0.001). Hemorrhage during the transection (85.0 ml vs 105.0 ml, p = 0.438) and hemorrhage per square centimeter (3.28 ± 0.86 ml/cm² vs 3.60 ± 1.12 ml/cm², p = 0.141) in the New-RF group were smaller than those in Habib-4X group with no significant difference.

Conclusion

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.

一种新型内部冷循环射频辅助肝横切装置

摘要

目的

为了评估与Habib-4X双极射频装置相比，新型内部冷循环双极射频装置在肝肿瘤切除术中的安全性和有效性。

方法

自2017年2月至2020年1月，共85例接受了射频辅助肝切除术的肝细胞癌患者被纳入研究，其中45例接受了新的内部冷循环双极射频（New-RF）治疗，40例接受了Habib治疗-4X双极射频（Habib-4X）。主要结局指标为肝横切速度，凝血组织宽度，出血量，输血率和手术时间。

结果

New-RF和Habib-4X组患者的基线特征无显着差异（p  > 0.05）。与Habib-4X相比，New-RF的平均肝横切速度更快（4.81±1.20 cm ² / min与3.64±1.08 cm ² / min，p  <0.001），凝血组织宽度更窄（1.42±0.23） cm ² vs 1.81±0.20 cm ²，p  <0.001），更少的手术时间（55.04±16.12 min vs 64.02±15.09 min，p  = 0.010），针路出血率更低（13.3％vs 35.0％，p  = 0.019）和较低的电极针碳化率（22.2％vs 77.8％，p <0.001）。 New-RF组的横断面出血（85.0 ml vs 105.0 ml，p  = 0.438）和每平方厘米出血（3.28±0.86 ml / cm ² vs 3.60±1.12 ml / cm ²，p = 0.141）小于Habib-4X组的患者无明显差异。

结论

新的内部冷循环双极射频是一种安全有效的肝切除辅助设备，具有更快的切除速度，更低的电极针碳化率和更精确的凝血范围。
