title: Early clinical experience with the da Vinci Xi Surgical System in general surgery.
abstract: The da Vinci Xi Surgical System (Intuitive Surgical Inc., Sunnyvale, CA, USA) has been released in 2014 to facilitate minimally invasive surgery. Novel features are targeted towards facilitating complex multi-quadrant procedures, but data is scarce so far. Perioperative data of patients who underwent robotic general surgery with the da Vinci Xi system within the first 6 month after installation were collected and analyzed. The gastric bypass procedures performed with the da Vinci Xi Surgical System were compared to an equal amount of the last procedures with the da Vinci Si Surgical System. Thirty-one foregut (28 Roux-en-Y gastric bypasses), 6 colorectal procedures and 1 revisional biliary procedure were performed. The mean operating room (OR) time was 221.8 (±69.0) minutes for gastric bypasses and 306.5 (±48.8) for colorectal procedures with mean docking time of 9.4 (±3.8) minutes. The gastric bypass procedure was transitioned from a hybrid to a fully robotic approach. In comparison to the last 28 gastric bypass procedures performed with the da Vinci Si Surgical System, the OR time was comparable (226.9 versus 230.6 min, p = 0.8094), but the docking time significantly longer with the da Vinci Xi Surgical System (8.5 versus 6.1 min, p = 0.0415). All colorectal procedures were performed with a single robotic docking. No intraoperative and two postoperative complications occurred. The da Vinci Xi might facilitate single-setups of totally robotic gastric bypass and colorectal surgeries. However, further comparable research is needed to clearly determine the significance of this latest version of the da Vinci Surgical System.
