title: Da Vinci Xi and Si platforms have equivalent perioperative outcomes during robot-assisted partial nephrectomy: preliminary experience.
abstract: The aims of this study were to compare the perioperative outcomes of da Vinci Xi to Si during robotic-assisted partial nephrectomy (RAPN) and to discuss the feasibility of our novel port placement scheme for the da Vinci Xi platform, to overcome the existing kinetic and technical difficulties we faced with the linear port placement in patients with a small body habitus. A retrospective data analysis of patients who underwent RPN using da Vinci Xi (n = 18) was carried out. The outcomes of the Xi group were compared with the Si group (n = 18) selected using a case-matched methodology. For da Vinci Xi, we applied the universal linear port placement in 12 patients and our modified port placement in the remaining 6 patients. The Xi group had a shorter mean docking time of 17.8 ± 2.6 min compared to the Si group of 20.5 ± 2.1 min (p = 0.002); otherwise, no significant difference was present with regard to the remaining perioperative variables (p > 0.05). The modified Xi port placement had a shorter mean console time of 70.8 ± 9.7 min compared to the universal linear port placement of 89.3 ± 17.2 min (p = 0.03). Moreover, it provided a broader field of vision with excellent robotic arms movement, minimizing collisions and allowing an easier and comfortable surgical assist. Da Vinci Xi appears to be feasible and safe during RPN with similar outcomes to Si. The novel Xi port placement makes surgery easier in patients with low BMI.
