超声引导下射频消融术治疗子宫肌瘤的临床应用

Applicaion of radiofreguency ablation induced by ultrasound for uterine myomas

目的探讨射频消融术治疗子宫肌瘤的临床疗效。方法选择自愿接受射频消融技术治疗子宫肌瘤的患者56例,在B超监视和引导下将射频治疗刀经阴道、宫颈置入病灶进行射频消融治疗,于手术后6、12个月随访。结果肌瘤大小、生长类型是影响疗效的主要因素,对黏膜下肌瘤射频消融治疗效果最佳,有效率达100.0%。该术式不适合治疗直径>5 cm的肌瘤。治疗后6个月71.79%月经恢复正常,58.07%痛经消失,59.18%下腹不适和膀胱、直肠压迫症状均消失。治疗后12个月82.05%患者月经恢复正常,74.19%痛经消失,73.47%下腹不适和膀胱、直肠压迫症状均消失。结论射频消融技术毁损肌瘤组织,使瘤体和子宫明显缩小,显著改善患者临床症状。

Objective To investigate the effectiveness of clinical application of radiofrequency ablation for uterine myomas.Methods Totally,56 cases of uterine myomas voluntarily accepting radiofrquency ablation were selected.A radiofrequency therapy knife with high-frequency electric current was inserted into the focus of myoma via vagina and cervix under the monitoring and directing of B-ultrasonography.All the patients were followed up 6,12 months after operation.Results Effectiveness of the treatment depended mainly on the diameter and type of myoma.With radiofrequency ablation was optimal for the patients of submucous myoma,with an overall effective rate of 100.0%.This operation is not the best choice for myoma that diameter is more than 5 centrimeters.Menstruation restored to normal in 71.79% of the patients;dysmenorrhea and pelvic pressure disappeared in 58.07% and 59.18% after 6 months of treatment.Menstruation restored to normal in 82.05% of the patients;Dysmenorrhea and pelvic pressure disappeared in 74.19% and 73.47% after twelve months of treatment.Conclusion Radiofrequency ablation could destroy myoma tissues causing obvious reduction of size of the tumor and uterus and relief of clinical symptoms.
