About
Dr. Osmar Kenji Yagi is a pioneering Brazilian surgical oncologist whose research focuses on advancing minimally invasive techniques for gastric cancer treatment. His work has been instrumental in challenging traditional open surgery paradigms, particularly through his influential 2016 paper "MINIMALLY INVASIVE SURGERY FOR GASTRIC CANCER: TIME TO CHANGE THE PARADIGM" (25 citations), which helped catalyze a shift toward laparoscopic and robotic approaches. As a founding member of the Brazilian Laparoscopic Oncologic Gastrectomy Group (BLOGG), Dr. Yagi has documented the evolution of these techniques in Brazil, highlighting both their potential and the barriers to widespread adoption. His landmark 2022 randomized trial (20 citations) provided critical evidence comparing short-term outcomes of robotic versus open gastrectomy, demonstrating reduced blood loss and pain. More recently, his 2024 propensity-matched analysis (5 citations) addressed the pressing question of whether robotic gastrectomy is equivalent to laparoscopic gastrectomy in Western populations. Dr. Yagi has also contributed to technique standardization through his 2020 work on robotic gastrectomy protocols. With cumulative citations exceeding 67, his research continues to shape surgical practice, offering patients less invasive options while rigorously evaluating oncological safety and feasibility.
