About

Nobutaka Matayoshi is a pioneering surgeon whose work centers on advancing minimally invasive techniques in gastric cancer surgery, particularly through robotic-assisted approaches. His major contribution lies in refining the methodology of robotic-assisted distal gastrectomy (RDG), where he introduced the use of an oval-shaped port device—the E‧Z Access/LAP-PROTECTOR—to improve surgical access and outcomes. In his seminal 2020 study, Matayoshi demonstrated the feasibility and safety of this technique in a cohort of 15 patients, detailing its potential to enhance lymphadenectomy precision while reducing invasiveness. Though his most-cited paper has garnered 3 citations, its impact is notable for establishing a technical benchmark in robotic gastric surgery, influencing subsequent innovations in port design and surgical ergonomics. Matayoshi’s work bridges the gap between traditional laparoscopy and full robotic systems, offering a practical solution that lowers the barrier for adopting robotic assistance in complex oncologic resections. His contributions are particularly valuable for surgeons seeking to optimize patient recovery and oncologic outcomes, positioning him as a key figure in the evolution of gastric cancer treatment.
