Ultrasound-guided microwave ablation in the treatment of thyroid benign tumors

Objective To compare the clinical effect between traditional operation and ultrasound-guided microwave ablation (MWA) in the treatment of thyroid benign tumor, and to explore the complications and short-term effect. Methods A retrospective analysis of 63 patients with thyroid benign tumor who were admitted to the Affiliated Huai'an Hospital of Xuzhou Medical University from January 2017 to December 2017 was conducted, and 30 patients in the observation group were treated by ultrasound-guided MWA, 33 patients in the control group received traditional surgical treatment. The therapeutic effects of the two groups were analyzed, and the wound cosmesis score, 24-hour postoperative pain score (VAS), hospitalization expenses, postoperative complication rate, intraoperative bleeding volume, length of hospital stay, operation time, changes in thyroid function index, changes in tumor volume, changes in inflammatory factors in the first day after operation, and assessment of daily living ability measured by the Barthel Index (BI) on the first day after operation were observed. Results Compared with the control group, patients in the observation group reported lower 24-hour postoperative VAS score, with shorter length of hospital stay, lower intraoperative hemorrhage volume, lower hospitalization expenses, shorter operation time, lower postoperative complication rate, as well as less influence on thyroid function, body trauma and life activity (P<0.05). The wound cosmesis score of the observation group was higher than that of the control group (P<0.05). In the observation group, the reduction of tumor volume was better compared to the control group, and the longer the postoperative time, the higher the reduction rate (P<0.05). Conclusions Ultrasound-guided MWA for thyroid benign tumor is a good way of operation with little damage, fewer complications and better cosmetic effect.
