Single-port robot-assisted hepatic left lateral sectionectomy using the da Vinci SP® system: A case report

Objective: The da Vinci SP® surgical system offers improvements and refinements for the robotic single-site procedures. Here, we report the first case performing the single-port robotic-assisted left lateral sectionectomy (LLS) for hepatic tumor using the da Vinci SP® surgical system, and demonstrate the safety and technical feasibility of this platform. Methods: A 69-year-old female patient with hepatic tumor underwent single-port robotic-assisted LLS using the da Vinci SP® system at the Chinese People's Liberation Army (PLA) General Hospital on December 27, 2021. And the clinical data, preoperative preparations, surgical procedures, and postoperative recovery of this patients were summarized. Results: The patient with hepatic tumor underwent successful single-port robotic-assisted LLS. The intraperitoneal operation time was 49 minutes and the estimated blood loss was 10 ml. No significant intraoperative complications were observed. The Visual Analogue Scale (VAS) pain intensity score was 3/10 in the immediate postoperative period and 1/10 on postoperative day one. The patient was discharged on postoperative day four. Conclusion: Herein, we report the first case of single-port robotic-assisted LLS for hepatic tumor using da Vinci SP® system, and this operation is technically safe and feasible. The present case indicated that the single-port robotic-assisted surgery is expected to further improve the application prospect of single-port surgery.
