Robot-Assisted Liver Resection With Versius Surgical System: COMPAR-L Prospective Study.

BackgroundWhile similar procedures can be performed using various robotic platforms across different surgical fields, no data exists on robotic liver resection (RLR) with the Versius robotic system (Cambridge Medical Robots-CMR Surgical). This study collected data on the first case series of hepatectomies using the Versius system.MethodsPatients who underwent liver resection of anterolateral segments using the Versius system at the General and Hepatobiliary Surgery unit of the University of Verona between July and December 2024 were enrolled. Experienced surgeons in RLR performed the resections. The short-term outcomes, timing, and cost of each surgical and non-surgical phase were analyzed.ResultsTen patients underwent robotic liver resection using the Versius platform for hepatocellular carcinoma (n = 2), liver metastases (n = 2), and benign lesions (n = 6) in the anterolateral segments. Eight patients had prior abdominal surgery, 2 had multiple lesions, and 6 had anatomical resections (ie, H23 n = 3, H2 n = 1, H3 n = 1, H5-subsegmentectomy n = 1). Hilar clamping was used in 5 patients, with a median total time of 30 min (IQR 15-40), median blood loss of 50.0 mL (IQR 50.0-100.0), and no intra- or post-operative complications. Median total operative time was 259.5min (IQR 183.0-347.0) with median parenchymal transection time of 83.0min (IQR 40.8-93.8). Median total cost of the procedure was €4146.5 (IQR 3608.5-4976.2), which included personnel, operating room, robotic platform, kit, and consumables costs.ConclusionsThis preliminary experience with liver resection using the Versius system demonstrated its feasibility and safety. To our knowledge, this is the first reported series of liver resections utilizing the Versius platform.
