About

Dr. Riki Ninomiya is a pioneering surgeon at the forefront of minimally invasive pancreatic surgery, with a focused expertise in robotic pancreaticoduodenectomy (RPD) and reduced-port techniques. His major contributions center on overcoming the technical hurdles of complex pancreatic resections through innovative surgical deployment. In his highly cited 2023 work (9 citations), Ninomiya introduced the "right lateral approach" to the superior mesenteric artery, a novel repositioning strategy that simplifies artery division and enhances safety in robotic procedures. Building on this, his 2024 study (3 citations) details a "single-site plus-two ports" method for reduced-port RPD, optimizing surgical field exposure while minimizing incisions—a technique previously unattainable with standard laparoscopy. Complementing these technical advances, his 2022 narrative review (3 citations) provides a comprehensive analysis of reduced-port pancreatectomy, contextualizing its evolution and challenges. Collectively, Ninomiya’s work has garnered growing attention for pushing the boundaries of robotic surgery, offering safer, less invasive options for patients undergoing complex pancreatic resections. His innovative approaches are shaping the next generation of surgical practice in hepatobiliary and pancreatic oncology.
