Simultaneous ileocolic and abdominoperineal resection using the da Vinci SP system for synchronous triple colorectal cancer: a case report

摘要

Robot-assisted surgery for colorectal cancer is gaining traction in Japan, particularly with the approval of the da Vinci SP system for insurance coverage in 2022. This system enables precise and flexible procedures through a single port accommodating three instrument arms and a camera. We present a case involving a 73-year-old man with synchronous tumors in the cecum, sigmoid colon, and rectum (Rb). Simultaneous resection was successfully performed using the da Vinci SP system by a robotic surgical team and a perineal team without complications. To our knowledge, this is the first reported case of simultaneous resection of triple colorectal lesions using this system. The single-port design and 360° rotating arms enhanced maneuverability and reduced the need for multiple incisions compared to conventional platforms. The da Vinci SP system shows promise for treating multi-lesion colorectal cancer cases, though further studies are required to validate its long-term efficacy and broader clinical utility.
