About

Chiharu Nakasu is a pioneering surgeon specializing in minimally invasive robotic gastrectomy for gastric cancer, with a particular focus on overcoming complex anatomical challenges. Her major contributions center on developing and refining novel surgical techniques that enhance precision and safety in robotic-assisted procedures. Notably, Nakasu demonstrated the feasibility of robotic total gastrectomy in a patient with situs inversus totalis—a rare condition where organs are mirrored—showcasing her ability to adapt advanced technology to exceptional cases (12 citations). She also introduced the left-handed ultrasonic shears technique, which improves ergonomics and dissection efficiency during robotic gastrectomy, as validated in a study of 67 patients (9 citations). Additionally, her "pincer approach" to the gastrosplenic ligament offers a safer method for mobilizing the stomach during total gastrectomy (4 citations). Through these innovations, Nakasu has expanded the boundaries of robotic surgery, providing reproducible solutions for challenging scenarios. Her work is highly regarded among minimally invasive surgeons and has been featured in leading surgical journals with accompanying video demonstrations, making her a key figure in advancing robotic gastrectomy techniques worldwide.
