About

Dr. Keigo Matsumoto is a leading figure in gastrointestinal surgical anatomy, with a focused expertise in the three-dimensional (3D) reconstruction of perigastric vasculature. His most impactful work, a comprehensive 2022 study, leverages enhanced multidetector-row computed tomography to meticulously map the complex anatomy of perigastric vessels. This research provides a critical preoperative roadmap for laparoscopic gastrectomy, directly enhancing surgical safety by reducing the risk of intraoperative vascular injury. By systematically re-evaluating and classifying perigastric vessel patterns, Dr. Matsumoto’s contributions bridge a vital gap between radiological imaging and precision surgery. His work, which has garnered significant attention in the field, is foundational for surgeons seeking to master the intricate vascular landscape of the stomach. Through this detailed anatomical re-appraisal, Dr. Matsumoto is not only advancing the technical execution of minimally invasive gastric cancer surgery but also setting a new standard for evidence-based preoperative planning in upper gastrointestinal oncology.
