Background:
Transoral endoscopic thyroidectomy vestibular approach (TOETVA) has become increasingly popular in the surgical treatment of thyroid cancer. However, its application in T3b disease has not been well-defined.
Methods:
We conducted a quasi-experimental study on patients with an intraoperative diagnosis of T3bN0M0 differentiated thyroid carcinoma from January 2019 to January 2021 in our institution. Surgical and early oncological outcomes were assessed.
Results:
Among 326 patients who underwent TOETVA for thyroid cancer, 12 cases had T3bN0M0 disease intraoperatively. The mean operation time was 136.67±7.32 minutes, with 7.17±0.83 mL of blood loss. No patients reported symptoms of postoperatively transient hypoparathyroidism, mental nerve, or recurrent laryngeal nerve injury. After radioactive iodine therapy, all patients had undetectable thyroglobulin, negative antithyroglobulin, and normal neck ultrasound.
Conclusions:
TOETVA seems to be a surgically and oncological safe method for differentiated thyroid cancer patients with small tumors invading strap muscle intraoperatively. The patients can be well-managed with endoscopic total thyroidectomy and postoperative radioactive iodine therapy. Further studies with a larger sample size and longer follow-up are needed to provide more solid evidence.
