Background:
The recently developed da Vinci single-port (SP) system offers potential advantages in maneuverability within narrower surgical spaces. This study aims to compare intra- and post-operative outcomes, technical advantages, and limitations of transoral resections using the da Vinci SP and da Vinci Xi systems for oropharyngeal squamous cell carcinoma (OPSCC).
Methods:
A single-center retrospective cohort study included patients with OPSCC who underwent transoral robotic surgery (TORS) after neoadjuvant chemotherapy (NCT). Data on pre-operative variables, intraoperative data, postoperative complications, and functional outcomes were collected.
Results:
A total of 209 patients (males: 175; mean age: 59.0 ± 9.3) were included (SP: n = 136; Xi: n = 73). A significantly lower docking time was measured for the SP group (5.7 ± 2.5 min vs. 10.0 ± 4.4 min; p <.001). Similarly, the console time was reduced for the SP group though not reaching statistical significance (76.3 ± 30.7 min vs. 88.1 ± 36.9 min; p =.06). A greater proportion of patients showed wide negative resection margins in the SP group (71 % vs. 56 %; p =.10), although not statistically significant. No significant differences were observed in complication rates or postoperative functional outcomes.
Discussion:
This study demonstrates the safety and efficacy of the da Vinci SP system in oropharyngeal surgery, with potential advantages in terms of reduced docking and console times. The findings suggest that the SP system offers improved maneuverability and instrument placement compared to the da Vinci Xi system.
