Abstract:Objective To investigate the therapeutic effect of ultrasound-guided laser ablation in the treatment of local recurrence of thyroid papillary carcinoma. Methods Forty-seven patients with local recurrence of thyroid papillary carcinoma in our hospital from December 2014 to September 2016 were involved. The patients received laser ablation under the guidance of ultrasound. The incidences of complications and serum thyroglobulin level of the patients before and after treatment were compared. The size, echo and blood flow of the nodules at 1, 3, 6 and 12 m after treatment were followed up. Results The incidence of postoperative nausea and vomiting was 19.15%, the incidence of hoarseness was 21.28%, the incidence of cough was 8.51%, and the incidence of jugular venous thrombosis was 6.38%. The volume and diameter of the nodules in 12 m after laser ablation treatment were significantly different from those in 1 m after treatment, there was a gradually decreasing trend within 12 m after treatment, and the differences were statistically significant (P < 0.05). The rates of disappearance of nodule echo and disappearance of blood flow signal at 12 m after treatment were lower than those at 1 m after treatment, the differences were statistically significant (P < 0.05). The serum thyroglobulin level after treatment was lower than that before treatment; the serum thyroglobulin level of the patients was in a decreasing trend from 1, 3, 6 m to 12 m after treatment, and the differences were statistically significant (P < 0.05). Conclusions Ultrasound-guided laser ablation has the advantages of safety, good prognosis, little trauma and fast recovery, and can effectively treat local recurrence of thyroid papillary carcinoma, therefore it can be expected as a choice of surgical treatment for local recurrence of thyroid papillary carcinoma.
