At our institution, four robotic platforms - da Vinci Xi, da Vinci SP, hinotori ^TM, and Hugo RAS - are used for robotic colorectal cancer surgery. Each platform has unique structural characteristics and clinical advantages. In this presentation, we focus on da Vinci Xi and hinotori^TM, using intraoperative videos to illustrate key differences in operability and perioperative outcomes, especially subcutaneous emphysema (SE). The da Vinci Xi system provides stable visualization and precise instrument control through its robust docking structure. It is also equipped with advanced technologies such as robotic staplers and integrated energy devices, making it highly suitable for complex and high-precision colorectal procedures. In contrast, the hinotori^TM platform features a pivot-based free-docking system that offers greater flexibility during setup. Although robotic staplers and energy devices are not currently integrated into this system, its docking architecture may help reduce abdominal wall pressure, potentially contributing to a lower risk of subcutaneous emphysema, as previously discussed in our publication (Surg Endosc, 2024). By presenting comparative surgical videos, we aim to highlight the specific features and advantages of each platform and provide practical insights for improving outcomes in robotic colorectal surgery, such as reducing the risk of subcutaneous emphysema.
