A Multicenter, Randomized, Controlled Clinical Study on the Feasibility and Safety of Gasless Transaxillary Posterior Endoscopic and Open Thyroidectomy for Papillary Thyroid Cancer.
To evaluate the feasibility and safety of gasless transaxillary posterior endoscopic thyroidectomy (Resection of thyroid lobe and isthmus, lymph node dissection in the central area of the affected side) and open radical thyroidectomy (Resection of thyroid lobe and isthmus, lymph node dissection in the central area of the affected side) as the current standard surgical treatment mode in terms of feasibility and safety of radical thyroidectomy.
• The patient's informed consent;
• 18 years old \< age \< 70 years old;
• Papillary thyroid carcinoma (Bethesda grade V-VI) was pathologically diagnosed by fine needle aspiration biopsy of the primary thyroid tumor before surgery;
• Color Doppler TI-RADS 4c-5 of primary thyroid tumor;
• The preoperative clinical staging is T1, N0-1a, M0 (see diagnostic criteria for details; according to AJCC-8th TNM tumor staging);
• It is expected that R0 surgical results can be obtained by performing single thyroid lobectomy and isthmus resection + ipsilateral central lymph node dissection;
• Preoperative ASA score I-III.
