Background:
Transoral endoscopic thyroidectomy vestibular approach (TOETVA) and gasless transaxillary endoscopic thyroidectomy (GTET) are 2 newly applied technologies. This study is to compare the 2 approaches from the aspects of effectiveness and safety.
Materials And Methods:
A total of 339 patients who underwent TOETVA or GTET with unilateral papillary thyroid carcinoma were enrolled in this study from March 2019 to February 2022. The 2 groups were compared in terms of patient characteristics, perioperative clinical results, and postoperative outcomes.
Results:
The operative time of the TOETVA group was significantly longer than the GTET group (141.39±16.11 vs. 98.45±12.24, P <0.05). The TOETVA group had advantages over GTET group when the reduction of parathyroid hormone was compared (19.18±17.43 vs. 23.07±15.72, P <0.05). Meanwhile, more parathyroids were detected in central neck specimens in GTET group (40/181 vs. 21/158, P <0.05). TOETVA had an advantage on total number of central lymph nodes over GTET (7.65±3.11 vs. 4.99±2.45, P <0.05), whereas the number of positive central lymph nodes was similar ( P >0.05). No differences were found between the 2 groups on other data.
Conclusions:
TOETVA and GTET are both safe and effective for unilateral papillary thyroid carcinomas. TOETVA has advantage on protection of inferior parathyroid glands and harvest of central lymph node dissection. Meanwhile, GTET can save more time compared with TOETVA. Surgeons and patients should freely choose the approaches based on their demands.
