目的：比较射频消融与微波消融对离体牛肝的作用效果。方法实验分为射频组与微波组，分别使用Cool-tip射频针与冷循环微波刀，均采用单针单次方式消融离体牛肝，比较两组间相同消融时间消融灶纵径、横径及体积。结果消融4、6、8 min，微波组消融灶纵径及体积均大于对应时间射频组消融灶纵径及体积（P＜0.05），消融10 min，两组消融灶纵径及体积差异均无统计学意义（P＞0.05）；消融4 min，微波消融灶横径大于对应时间射频消融灶横径（P＜0.05），消融6、8、10 min，两组消融灶横径差异均无统计学意义（P＞0.05）。结论与射频相比较，微波的热效率更高，消融速度更快，但随着消融时间延长，最终两者可取得相近的消融效果。

Objective To compare the effect of radiofrequency ablation (RFA)and microwave abla-tion (MWA)in vitro bovine liver. Methods The experiment was divided into two groups:Group RFA and Group MWA,respectively,useing Cool-tip radiofrequency eletrode and Water-cooled microwave antenna by single-needle and single-ablation method. Ablation lesions in longitudinal diameter (LD),transverse diameter (TD)and volume (V)in the same ablation time between the two groups were analysed. Results LD and V of MWA lesions are greater than the corresponding time RFA lesions in 4 minutes,6 minutes and 8 minutes (P<0.05 ). LD and V of MWA lesions have no statistical significance with LD and V of RFA lesions in 1 0 mi-nutes (P>0.05 ). TD of MWA lesions was greater than that of RFA lesions in 4 minutes (P<0.05 ). TD of MWA lesions has no statistical significance in RFA lesions of 6 minutes,8 minutes and 1 0 minutes(P>0.05).Conclusions MWA has higher thermal efficiency and faster ablation speed than RFA. But with extension of time,both methods can achieve similar effect of ablation.
