About

Dr. Sumio Matsumoto is a leading figure in the advancement of minimally invasive surgery in Japan, with his research primarily centered on endoscopic and laparoscopic techniques. His most significant contribution is his leadership in tracking the evolution of these procedures through the Japan Society for Endoscopic Surgery (JSES). His landmark paper, "Update on endoscopic surgery in Japan: Results of the 16th National Survey," provides a comprehensive analysis of surgical trends for 2020 and 2021, documenting the explosive growth of laparoscopic cholecystectomy since its introduction in 1990. This work, which has garnered 17 citations, serves as a critical resource for understanding the adoption and standardization of minimally invasive approaches across the nation. By meticulously cataloging procedural volumes and outcomes, Dr. Matsumoto has helped shape clinical guidelines and training protocols, cementing his role as a key architect of modern Japanese surgical practice. His ongoing survey work continues to influence how surgeons and policymakers evaluate the safety and efficacy of endoscopic surgery.
