About

Naotsugu Haraguchi is a pioneering robotic surgeon whose work centers on advanced minimally invasive approaches to gastrointestinal oncology, particularly gastric cancer. His major contribution lies in demonstrating the technical feasibility and safety of completely robotic total gastrectomy combined with thrombectomy and portal vein reconstruction for patients with gastric cancer and portal vein tumor thrombus (PVTT)—a condition historically associated with dismal prognosis and treated only through highly invasive open surgery. By detailing this complex robotic procedure, Haraguchi has expanded the surgical armamentarium against advanced gastric malignancies, offering a less morbid alternative that may improve outcomes for this challenging patient population. His landmark 2022 paper on this technique, cited 10 times, serves as a foundational reference for surgeons seeking to adopt robotic approaches in oncologically demanding scenarios. Through this work, Haraguchi has established himself as a leader in pushing the boundaries of robotic surgery, demonstrating that even the most intricate vascular reconstructions can be performed with precision and minimal access, ultimately advancing the field toward safer, more effective cancer care.
