Clinical effect of ultrasound-guided microwave thermal ablation for treating benign thyroid nodules
Objective To evaluate the effectiveness and safety of ultrasound-guided microwave ablation technique in the treatment of benign thyroid nodules.Methods A total of 3985 nodules in 2913 patients with pathologically confirmed benign thyroid nodules during 2016-2023 were analyzed retrospectively.The one-time ablation success rate,incidence rate of postoperative complications and side effects were evaluated.For 1890 ablation nodules in 1449 patients with a median follow-up period of 12 months,the nodule volume re-duction rate (VRR),recurrence rate,re-ablation rate and technical effective ablation rate were evaluated in postoperative 1,3,6,12,24 months and more.Results The success rate of one-time ablation in all patients was 99.7％ (3972/3985),the technical effective ablation rate was 88.6％ (535/604),the recurrence rate was 3.1％ (59/1890) and the re-ablation rate was 0.7％ (13/1890).In the follow-up nodules,VRR in postopera-tive 1,3,6,12,24 months and more was (-17±430)％ (n=727),(48±152)％ (n=643),(72±38)％ (n=573),(83±20)％ (n=604),(88±18)％ (n=279),respectively.In all patients,the incidence rate of major complications was 2.57％,the incidence rate of minor complications was 2.06％,and the incidence of side effects was 3.09％.Conclusion Ultrasound-guided microwave ablation of thyroid nodules is an effective and safe method for the treatment of benign thyroid nodules.
