Background/Aim:
This study compared the initial outcomes of gas-insufflation one-step single-port transaxillary (GOSTA) robotic thyroidectomy with traditional open thyroidectomy for thyroid cancer at a single institution.
Patients And Methods:
A retrospective analysis was conducted on 77 patients who underwent thyroidectomy for differentiated thyroid cancer from January to June 2024. Exclusion criteria included benign nodules, Graves' disease, and previous thyroid surgeries. Two surgeons performed the procedures, with one having no prior robotic surgery experience.
Results:
Of the 77 patients, 48 underwent open thyroidectomy and 29 underwent GOSTA thyroidectomy. The GOSTA group had a significantly lower mean age (40.1 vs. 47.6 years, p=0.002) and a higher proportion of female patients (p=0.040). The open group patients had more harvested lymph nodes than the GOSTA group patients (7.9 vs. 2.4, p<0.001). The GOSTA group patients had longer operation time (156.4 vs. 80.6 min, p<0.001), and had extended hospital stay than the open group patients (5.9 vs. 3.4 days, p<0.001). Complication rates were similar between the groups.
Conclusion:
GOSTA robotic thyroidectomy provides comparable safety and effectiveness to open thyroidectomy, with improved cosmetic outcomes despite longer operation times and hospital stays. This technique is feasible for surgeons without prior robotic experience, offering a viable alternative for patients prioritizing cosmetic results.
