Advantages of ultrasound-guided radio frequency ablation for benign thyroid nodules

To explore the effect of ultrasound-guided radio frequency ablation (RFA) on patients with benign thyroid nodules (BTN). A total of 73 patients with BTN admitted to our hospital from March 2017 to August 2019 were selected, of which 42 patients were treated with ultrasound-guided radio frequency ablation (RFA group) and 31 patients were treated with traditional surgery (tradition-operation group). The operation condition, pain score, cure rate, postoperative cosmetic score, complication rate, changes of ablation area volume before and after ablation, between the two groups were observed and compared. The average operation time, postoperative hospitalization, intraoperative blood loss and pain score in the tradition-operation group were higher than those in the RFA group. The cure rate and postoperative cosmetic score in the RFA group were notably higher than those in the tradition-operation group. The incidence of complications in the two groups was not statistically different (P > 0.05). The maximum diameter and volume of nodules were notably reduced at the 1st, 3rd and 6th months after ablation (P < 0.05), and the maximum diameter and volume at the 1st, 3rd and 6th months after ablation were significantly different from that before treatment (P < 0.05). After treatment, the content of T3, T4 and FT4 in RFA group were remarkably lower than that in RFA group (P < 0.05). In conclusion, ultrasound-guided RFA can reduce pain and improve curative effects in patients with BTN, which is worthy of clinical promotion.
