RESUMO
The new da Vinci® single-port (SP) robotic system, which utilizes a smaller incision and work space compared to the previous versions, is suitable for thyroidectomy. This study aimed to evaluate the learning curve for SP transaxillary robotic thyroidectomy (SP-TART) in a single-center. Fifty consecutive patients who underwent SP-TART between October 2021 and April 2022 in Seoul St. Mary's Hospital in Seoul, Korea, were included in this retrospective analysis. We examined the clinicopathological characteristics and short-term surgical outcomes and assessed the learning curve for SP-TART using cumulative summation analysis. The mean operation time was 57.8 ± 14.1 min, and the mean tumor size was 1.0 ± 0.7 (range, 0.3-3.7) cm. The patients were discharged approximately 2 days after surgery, and only two (4%) patients developed postoperative complications, including drainage-site bleeding and surgical site infection. Risk factors for long operation time were thyroiditis, amount of blood loss, and lymph node metastasis. The learning curve for SP-TART was 20 cases for the experienced robotic surgeon. SP-TART is technically feasible and safe with a short incision length and short operation time. It is a valuable alternative operative option with good surgical outcomes and outstanding cosmetic results.
