About

Dr. Tsutomu Iwasa is a leading figure in the advancement of surgical robotics for gastrointestinal oncology, specializing in the development of minimally invasive tools for intraluminal surgery. His primary research focuses on creating robotic-assisted flexible endoscopes to enhance the precision and ergonomics of procedures like endoscopic submucosal dissection (ESD), a critical treatment for early-stage gastrointestinal cancer. Dr. Iwasa’s major contributions include the design and validation of a novel robotic endoscope with single-hand control, which significantly improves maneuverability during complex dissections. His landmark 2018 study, demonstrating this system in an ex vivo porcine stomach, has garnered 62 citations, underscoring its influence on the field. He further advanced this work in a 2020 feasibility study (31 citations) exploring a surgical robot for intraluminal access, aiming to replace conventional percutaneous surgery with a less invasive approach that preserves patient quality of life by eliminating skin incisions. Through these innovations, Dr. Iwasa is shaping the future of endoscopic surgery, making it safer and more accessible for patients worldwide.
