摘要： 目的 探讨“杠杆撬离法”预防甲状腺良性结节微波消融过程中热损伤并发症的安全性、有效性。方法 348例甲状腺良性结节行超声引导下微波消融治疗，其中174例采用“液体隔离带法”预防热损伤，即“液体隔离带”组；另174例采用“杠杆撬离法”预防热损伤，即“杠杆撬离法”组，术后随访1~12月，观察严重并发症的发率及结节残留发生率。结果 348例甲状腺良性结节均在超声引导下完成微波消融治疗，手术严重并发症均为声音改变，其中“液体隔离带”组3例，发生率为1.7%“；杠杆撬离法”组4例，发生率为2.3%，两组严重并发症的发生率比较差异无统计学意义（P>0.05）。术后随访1~12月，“液体隔离带”组17例结节边缘有少量残留组织，残留发生率为9.8%“；杠杆撬离法”组19例结节边缘有少量残留组织，残留发生率为10.9%，两组间结节残留发生率比较差异无统计学意义（P>0.05）。结论“杠杆撬离法”是预防甲状腺良性结节微波消融过程热损伤并发症的简便有效方法。

Abstract: Objective To assess the safety and efficacy of“leverage pry-off method”for preventing thermal injury during microwave ablation of benign thyroid nodules. Methods From July, 2017 to September, 2019, a total of 348 patients with benign thyroid nodules underwent ultrasound-guided microwave ablation. For protecting from thermal injury during the ablation, "hydrodissection technique" was used in 174 of the patients (admitted from July, 2017 to August, 2018) and "leverage pry-off method" in the other 174 patients (admitted from September, 2018 to September, 2019). All the patients were followed up for 1 to 12 months after the operation for observation of severe complications and nodular residues. Results Ultrasound- guided microwave ablation was completed in all the 348 patients. The most common severe complication associated with the ablation was voice change, occurring in 3 cases (1.7% ) in "hydrodissection technique" group and in 4 (2.3% ) in the "leverage pry-off method" group, showing no significant difference between the two groups (P>0.05). During the follow-up, no significant difference was found in the rate of nodular residues between the "hydrodissection technique" group and "hydrodissection technique" group (9.8% vs 10.9% (P>0.05). Conclusions The "leverage pry-off method" is simple and effective for preventing thermal injury during microwave ablation of benign thyroid nodules.
