Background:
We conducted this study to report our novel robotic thyroidectomy using gas-insufflation one-step single-port transaxillary (GOSTA) approach and compare it with a conventional transaxillary (CTA) approach using a retraction method for intraoperative and postoperative outcomes.
Methods:
We retrospectively analyzed 354 patients who underwent robotic thyroidectomy between January 2019 and April 2023. Of these patients, 143 underwent the procedure through the GOSTA approach, which involves a small incision of 3 cm along the axillary folds with both arms down and a gas-insufflation, from skin flap creation to the completion of thyroidectomy as a one-step single-port procedure without the need for a retractor. The remaining 211 patients underwent the CTA approach. We analyzed the GOSTA approach and compared the surgical outcomes of the GOSTA (n = 100) and CTA (n = 167) approaches in patients with differentiated thyroid cancer who underwent thyroid lobectomy.
Results:
Out of the 143 patients who underwent the GOSTA approach, 12 underwent total thyroidectomy and 9 underwent lateral neck lymph node dissection with total thyroidectomy. GOSTA-thyroid lobectomy was performed on 122 patients; of these, 100 were diagnosed with differentiated thyroid carcinoma. A comparative study with the CTA approach was only conducted in patients who underwent thyroid lobectomy. No significant differences were found in operative time, hospital stay, or complications between the two groups.
Conclusions:
Despite proceeding in one-step with a single smaller incision, from skin flap creation to the completion of thyroidectomy, the GOSTA approach is as feasible and safe as the CTA approach. Additionally, the GOSTA approach allows for thyroidectomy without using a retractor and reduces the workload for the surgeon and assistants.
