506 Evaluation of the CMR Versius® Surgical Robot in Wales for Anterior Resections: A Retrospective Multicentre Study

Abstract Aim The CMR Versius® surgical robot offers potential advantages over traditional laparoscopic and open surgical techniques. This study evaluates its implementation in Wales for Anterior Resection procedures, with a focus on resource utilisation, intraoperative efficiency, and postoperative outcomes. Method This retrospective, multicentre study reviewed robotic Anterior Resection surgeries performed with the Versius® system across three hospitals in Wales between 22/06/2022 and 27/06/2024. Data collection focused on operative metrics, patient outcomes, and perioperative parameters to evaluate the system's effectiveness and safety. Results A total of 117 robotic Anterior Resection procedures were conducted across the three participating hospitals. The average duration of robotic surgeries was 4 hours and 43 minutes, with 36.23% of the operative time involving active use of the Versius® robotic system. Conversion to open surgery occurred in 5.13% of cases (n=6), none of which were related to device malfunctions. The overall complication-free rate was 68.38% (n=80), with no recorded perioperative mortality. Postoperatively, an average maximum haemoglobin drop of 24.89 g/L from baseline to day five, and an average maximum C-reactive protein rise of 125.32 mg/L was observed. Conclusions The implementation of the Versius® surgical robot has successfully facilitated a transition from open and laparoscopic methods to a more precise, minimally invasive approach for Anterior Resection surgeries in Wales. This study underscores the system's reliability, safety, and potential for broader adoption, supporting the continued integration of robotic-assisted surgery with the Versius® platform to enhance patient care and surgical outcomes.
