Background:
There is an increased use of endoscopic thyroidectomy (ET), including robotic-assisted thyroidectomy (RT), to avoid postoperative scars on the anterior neck. The objective of this study was to compare the surgical and oncologic outcomes between ET and conventional open thyroidectomy (COT) for differentiated thyroid carcinoma (DTC).
Methods:
We reviewed 4129 patients with DTC who underwent thyroid lobectomy at Seoul St. Mary's Hospital (Seoul, Korea) from January 2009 to December 2014. Patients were categorized according to the type of surgery and statistically compared using propensity score matching analysis.
Results:
The mean operation time was significantly longer in the ET group than in the OT group (101.2 ± 26.2 min vs. 86.4 ± 27.0 min, p < 0.001). The number of harvested lymph nodes was significantly lower in the ET group than in the OT group (5.5 ± 4.2 vs. 8.3 ± 6.2, p < 0.001). There was no significant difference in the recurrence rate between the two groups (p = 0.879). Kaplan-Meier analysis revealed no significant difference in the disease-free survival after propensity score matching (p = 0.811). The mean follow-up duration was 90.4 ± 21.0 months.
Conclusions:
Transaxillary ET including RT for DTC is a safe and feasible alternative to COT with a cosmetically desirable outcome. Further studies are required to confirm our results.
