Masaki Mandai

About

Dr. Masaki Mandai is a leading figure in gynecologic robotic surgery and minimally invasive oncology, whose work is shaping the future of surgical practice in Japan. His research centers on standardizing complex robotic procedures, advancing telesurgery, and improving surgical education. A key contribution is his leadership in developing the "Clinical practice guidelines for telesurgery 2022" (36 citations), a foundational document for expanding surgical access. He has also driven cross-disciplinary consensus on robot-assisted pelvic lymph node dissection, bridging colorectal, urologic, and gynecologic surgery to create a unified anatomical understanding. Dr. Mandai’s impact is evident in his multi-institutional surveillance of gynecologic robotic surgeries (12 citations) and his advocacy for technical certification systems, ensuring quality and safety. Notably, he is pioneering live streaming systems for robotic surgery with bidirectional discussion, transforming surgical training. His work on nationwide trends in laparoscopic and robot-assisted surgery provides critical data for healthcare policy. Through these efforts, Dr. Mandai is not only advancing surgical techniques but also building the infrastructure for a more accessible, standardized, and educational future in gynecologic oncology.
