Abstract
Objective: To investigate the application value of ultrasound-guided preciselocalization of carbon nanoparticles in thyroid microfoci resection. Methods: Sixty patients with thyroid microlesions classified as class III or above by Tl-RADS were collected and randomly divided into experimental group (n = 30) and control group (n = 30). The experimental group was treated with ultrasound-guided carbon nanoscale staining for precise localization and surgical resection, while the control group was treated with ultrasound localization and surgical resection. The time of complete lesion resection, intraoperative blood loss, success rate of oneprecise lesion resection and the amount of tissue excised were compared between the two localization methods. Results: In the experimental group, the time of complete resection was (18.10 ± 5.81) min, the amount of intraoperative bloodloss was (20.30 ± 8.71) ml, the weight of resected tissue was (15.8 ± 6.6) g, and the success rate of one accurate resection was 96.6% (29/30). In the controlgroup, the time of complete resection was (18.10 ± 5.81) min, the amount of intraoperative blood loss was (30.20 ± 10.70) ml, the weight of resected tissue was (28.50 ± 9.30) g, and the success rate of one precise resection was 76.6% (23/30). The time to find the lesion in the experimental group was significantly shorter than that in the control group (P < 0.05). The intraoperative blood loss, the amount of resected tissue and the success rate of mass localization in the experimental group were significantly better than those in the control group (P< 0.05). Conclusions: Compared with ultrasound localization, ultrasound-guided preciselocalization of nano-carbon staining can help surgeons to quickly and accurately find thyroid microlesions during operation, reduce the amount of normal thyroid tissue removed, and improve the success rate of surgery.
