Abstract：Objective: To evaluate the efficacy and safety of ultrasound-guided percutaneous microwave ablation(US-PMWA) in papillary thyroid microcarcinoma(PTMC), and compare with endoscopic surgery(ET). Methods: Twenty patients with US-PMWA were analyzed retrospectively. Conventional ultrasound, contrast-enhanced ultrasound and thyroid function tests were performed at 1-, 3-, 6- and 12- months to evaluate the efficacy and safety of US-PMWA. Thirty-eight patients underwent endoscopic thyroidectomy for PTMC. The postoperative hospital stay, cost, and complications were compared with each other in two groups. Results: The volume of 20 nodules with US-PMWA reduced during follow-up. No suspicious metastatic lymph nodes were found in the neck. The thyroid function indexes were within normal reference range before and after microwave ablation. The average hospital-stay days, hospitalization costs and complication rate with US-PMWA were (1.70±0.57) days, (14 695.45±1 637.35) yuan and 5.0%(1/20). The hospital-stay days, hospitalization costs and complication rate with ET were (4.78±1.03) days, (20 596.71±2 192.25) yuan and 10.53%(4/38). The hospitalization days and costs were different between two groups(P<0.05), whereas the complication rate was not(P>0.05). Conclusion: With its minimally invasion, beauty and convenience, US-PMWA is suitable for PTMC without lymph nodes and distant metastasis.
