About

Dr. Keigo Nakashima is a pioneering surgeon specializing in minimally invasive gastrointestinal oncology, with a focused expertise in robotic-assisted gastrectomy and advanced reconstructive techniques. His major contribution lies in addressing one of the most technically demanding challenges in robotic gastric surgery: intracorporeal esophagojejunostomy following total or proximal gastrectomy. Recognizing the inherent difficulties of this procedure compared to distal anastomoses, Dr. Nakashima developed and published a novel, safer, and simpler technique that combines a linear stapler with barbed suture devices. This innovation, detailed in his 2023 case series, reduces operative complexity and enhances patient safety, marking a significant step forward in robotic surgical oncology. While his work is early in its citation impact (4 citations), it represents a critical technical refinement for surgeons worldwide. Dr. Nakashima’s dedication to perfecting high-stakes robotic procedures positions him as an emerging leader in the field, offering reproducible solutions that may soon become standard practice for complex gastric cancer surgeries.
