About

Yu-Tang Chang is a leading colorectal surgeon whose research centers on advancing minimally invasive surgical techniques for rectal cancer, with a particular focus on robotic-assisted procedures. His most notable contribution is the development and refinement of the single-docking technique for robotic total mesorectal excision (TME), a complex operation requiring precise dissection in the deep pelvic cavity. In his landmark 2017 study, Chang demonstrated the feasibility and safety of this approach in 95 patients with stage I-III rectal adenocarcinoma, leveraging the robotic system’s high-definition 3D vision and articulating instruments to improve surgical precision. This work, which has garnered 28 citations, has helped establish robotic TME as a viable alternative to traditional laparoscopic or open surgery, potentially reducing complications and improving oncologic outcomes. Chang’s research addresses a critical challenge in colorectal surgery—achieving complete tumor removal while preserving pelvic nerve function—and his single-docking technique simplifies the workflow, making robotic surgery more accessible. His contributions continue to influence surgical practice and inspire further innovation in robotic colorectal oncology.
