Perioperative Safety, Feasibility, and Oncologic Utility of Transoral Robotic Surgery with Da Vinci Xi Platform

Transoral robotic surgery (TORS) is a common modality for treatment of oropharyngeal and laryngeal cancer. Current FDA approval extends to the da Vinci S and Si platforms. Many hospitals are adopting the da Vinci Xi platform. Reports of head and neck surgical outcomes with this platform are scant. This study reports outcomes of TORS procedures performed with the da Vinci Xi platform including perioperative adverse events, functional outcomes, and short-term local control. A retrospective review of TORS performed with the da Vinci Xi platform is undertaken. Twenty-two consecutive TORS cases with the Xi platform are reviewed. Procedures performed include radical tonsillectomy, base of tongue resection, and lingual tonsillectomy. Two bleeding events occurred (9% of cases), both of intermediate severity as per Mayo criteria. Three procedures resulted in positive margin status, early in the case series, and two were cleared with revision resection. One-year local control rate, where available, is 100%. There were no perioperative deaths, long-term gastrostomy dependence, or performance of tracheostomy. Advantages of this platform include ease of robot deployment and setup. Disadvantages include increased width of instrumentation compared with previous platforms with crowding of access. The availability of a specific robotic platform may be dictated by hospital-wide policy across service lines. This report suggests that the da Vinci Xi permits performance of TORS with safety and oncologic outcomes similar to previous platforms; however, long-term follow-up is needed.
