About
Keishi Yamashita is a leading gastrointestinal surgeon whose research centers on advancing minimally invasive surgical techniques for gastric, esophageal, and rectal cancers. His major contributions lie in rigorously evaluating the safety and efficacy of robotic-assisted surgery compared to conventional laparoscopic approaches. Through propensity score-matched analyses and clinical trials, Yamashita has demonstrated that robotic-assisted laparoscopic surgery (RALS) for rectal cancer offers comparable or improved short-term outcomes, even in complex cases following neoadjuvant chemoradiotherapy. His work on postoperative pancreatic fistula after gastrectomy—a severe complication—has helped refine surgical practices to reduce life-threatening risks. With over 100 citations across his most influential papers, Yamashita’s impact is evident in his meticulous focus on minimizing postoperative complications, such as recurrent laryngeal nerve injury during robot-assisted esophagectomy. Notably, he led a phase II trial confirming the safety and feasibility of robotic distal gastrectomy for stage IA gastric cancer, a landmark study that supports broader adoption of robotics in oncologic surgery. His research continues to shape evidence-based guidelines for robotic gastrointestinal surgery.
