射频治疗子宫肌瘤50例临床分析

The RF-treatment method to hysteromyoma through ultrasound analysis

目的 探讨子宫肌瘤射频治疗的应用范围并观察其疗效。方法 5 0例共 5 5只肌瘤射频治疗术中计算肌瘤平均回缩率、三维漏空率。术后 1、3、6个月复查 ,以肌瘤消失 ,临床无任何不适为治愈 ;肌瘤缩小、症状缓解为好转 ;肌瘤无明显缩小 ,症状无好转为无效。结果 直径 <3cm肌瘤平均回缩率 >70 % ,三维漏空率 <1% ,有效率 10 0 % ;3～ 5cm肌瘤平均回缩率 5 0 %～ 6 0 % ,三维漏空率 2 6 2 % ,有效率 96 4 % ;>5cm肌瘤平均回缩率 <5 0 % ,三维漏空率 4 5 5 % ,有效率 85 71%。统计分析显示 :直径 <3cm和直径为 3～ 5cm组比较 ,肌瘤治疗效果差异无显著意义 ;直径 <3cm、3～ 5cm和 >5cm组比较差异有显著意义。结论 直径 5cm以下肌瘤是射频治疗的适应证 ,5cm以上肌瘤应改进治疗方法或采用其他治疗手段。

Objective To study the application of RF-tretament to hysteromyoma and observe its therapeutic effects.Methods To calculate the average rate of the shrinking and the three-dimension rate of the leak in 50 cases with hysteromyoma,total of 55 myoma bodies were treated with RF-therapeutics,then re-examined in 1st,3rd,6th month afterward respectively.Results The results can be witnessed as follows:when myoma was smaller than 3cm,its average shrinking rate higher than 70%,its three-dimension leaking rate lower than 1%,thus the 100% effective rate was reached.If the myoma was between 3～5cm,the rates were 50% to 60%,2.62% and 96.4% respectively,while when it was bigger than 5cm,the rates lower than 50%,4.55% and 85.7% respectively.The obove results demonstrated the difference of the therapeutic efficiency was not marked,when one smaller than 3cm with one between 3cm and 5cm.However,the comparisons among the 3 groups showed the therapentic efficienly had marked difference.Conclusion The myoma smaller than 5cm is adaptable to the RF-therapeutics,while the one bigger than 5cm,RF therapeutic means should be improved or other therapeutic be adopted.
