Yasuo Sumi

About

Dr. Yasuo Sumi is a leading colorectal surgeon whose research centers on advancing surgical techniques for colorectal cancer and managing complex postoperative complications. His most impactful work, the 2018 review "Recent updates in the surgical treatment of colorectal cancer" (111 citations), synthesizes rapid technological and clinical trial advances to guide optimal, tailored patient care. Dr. Sumi is also a pioneer in robotic surgery education, demonstrated by his study on learning curves for the da Vinci® Surgical System, which distinguishes skill acquisition between expert and non-expert laparoscopic surgeons. Notably, he has developed innovative solutions for rare, intractable conditions, such as combining a gracilis muscle flap with a laparoscopic transabdominal approach to effectively treat post-prostatectomy rectourethral fistula—a challenging complication with no established standard of care. Through these contributions, Dr. Sumi bridges cutting-edge technology and practical surgical mastery, significantly impacting both routine colorectal cancer treatment and the management of complex surgical sequelae.
