Transoral Robotic Thyroidectomy: Comparison of Surgical Outcomes Between the da Vinci Xi and Si

초록

Introduction: The surgical outcomes for procedures using da Vinci Xi were compared with those of da Vinci Si in transoral robotic thyroidectomy (TORT). Materials and Methods: The medical records were retrospectively reviewed. Patients were classified into 2 groups (da Vinci Xi vs. da Vinci Si) and surgical outcomes were analyzed. Results: Each group comprised 58 patients. The postoperative pain scores at operation day 0 were lower, the hospital stays were shorter, and the number of retrieved central lymph nodes in the papillary thyroid carcinoma patients were greater in the Xi group than in the Si group. There were no significant differences between groups in either vocal cord palsy or hypoparathyroidism rates. There were no TORT-specific complications in the Xi group. There was no conversion to endoscopic or conventional open thyroid surgery in both groups. Conclusions: TORT could be performed safely with both da Vinci Si and Xi systems.
