Background: Previously, we have reported the feasibility of retroauricular (RA) robotic thyroidectomy. Despite its promising surgical outcomes, there were certain intrinsic mechanical limitations inherent to the da Vinci Si System. Since the advent of an upgraded model, the Xi System, we have actively incorporated the new model into performing RA thyroidectomy. Here, we intend to verify the feasibility of RA robotic thyroidectomy using the new da Vinci Xi System with comparison of the former Si-applied surgery.
Methods: There were total 165 consecutive patients who received RA robotic thyroidectomy from January, 2013 to February, 2016. The patients were divided into two groups: Si (n=125) and Xi (n=40) group. Perioperative and treatment outcomes were compared and analyzed.
Results: Compared with the previous system, new da Vinci Xi system enabled insertion of an extra third robotic instrumental arm. Unlike the previous robotic surgical technique, the robotic dissection could be initiated immediately after the establishment of working space and the resulting total operation time could be significantly decreased. There was no difference in the surgical completeness as confirmed by postoperative thyroglobulin levels. Additionally, flexed endowrist instruments equipped with the ERBE® system could be mounted further facilitated the operation. There were no significant differences in postoperative complications between the two groups such as vocal cord palsy, seroma, or bleeding.
Conclusion: The RA robotic thyroidectomy with the new Xi System can greatly facilitate the robotic surgery with comparable or improved surgical outcomes. Its application is expected to open up a new era of robotic neck surgery.
