Background: Transoral endoscopic thyroidectomy using the vestibular approach (TOETVA) is a novel technique for thyroid cancer surgery. We aimed to review our initial experiences with TOETVA for the management of thyroid carcinoma, using retrospective analyses of a larger single-center case series.
Methods: From September 2016 to April 2018, 132 patients with thyroid cancer underwent TOETVA. A three-port technique through the oral vestibule was used to perform endoscopic thyroidectomy with ipsilateral central compartment dissection using conventional laparoscopic instruments, and an endoscopic retractor that we developed.
Results: All patients had papillary thyroid carcinoma. Less-than total or total thyroidectomy with ipsilateral central compartment node dissection was performed (124 vs. 8). The mean operation time was 87.6 min (range 56-213 min). The average number of lymph nodes resected was 2.6 (range 1-12). Six patients experienced transient hoarseness, which was resolved within 3 months. Most of the patients were discharged within 3 days after surgery.
Conclusions: In this large series from a single center, we found that TOETVA with the endoscopic retractor can be performed safely and radically in selected patients with thyroid cancer.
