About

Kenji Okita is a leading figure in the advancement of minimally invasive colorectal surgery, with a particular focus on robotic and laparoscopic techniques for treating colon and rectal cancers. His work is distinguished by pioneering applications of novel surgical platforms and rigorous validation of oncologic outcomes. Dr. Okita made history by performing the first-ever colon cancer surgery using the hinotori Surgical Robot System, a next-generation platform with eight-axis operating arms and a flexible 3D viewer, demonstrating its feasibility and potential advantages in right hemicolectomy (29 citations). He is also the principal investigator of the PRODUCT trial, a landmark Japanese multicenter prospective study that rigorously evaluated laparoscopic surgery for locally advanced rectal cancer using standardized circumferential resection margin (CRM) assessment and total mesorectal excision (TME) quality—critical indices for oncologic safety (19 citations). Additionally, Dr. Okita has contributed to standardizing transperineal minimally invasive abdominoperineal excision for rectal cancer, reporting favorable short-term outcomes. Through these efforts, he is shaping the future of colorectal surgery by integrating cutting-edge robotics with evidence-based, quality-controlled surgical protocols.
