About
Dr. Masaru Hayami is a pioneering minimally invasive surgeon whose work centers on advancing surgical techniques for gastric and esophagogastric junction (EGJ) cancers. His primary research focuses on refining proximal gastrectomy—a stomach-preserving procedure—to improve patient outcomes and quality of life. Dr. Hayami’s major contributions include developing and validating novel reconstruction methods that reduce post-operative complications. His 2024 study on the safety of the robotic double-flap technique (DFT) during the introductory phase, compared to laparoscopic procedures, demonstrated comparable safety and efficacy, earning 9 citations. He also introduced the "sandwiching method" for hepatic left lateral segment inversion, which simplifies access to the esophageal hiatus during laparoscopic and robotic gastrectomy, cited 5 times. Most recently, in 2025, Dr. Hayami proposed the Non-Flap Tunnel Technique (NFTT), a novel reconstruction method designed to prevent reflux after proximal gastrectomy, offering a simpler alternative to DFT. With cumulative citations reflecting his growing influence, Dr. Hayami’s work is shaping the future of minimally invasive gastric cancer surgery, making him a key figure for students and researchers interested in surgical innovation and oncologic outcomes.
