About

Dr. John G. Armstrong is a pioneering colorectal surgeon whose research focuses on advancing minimally invasive surgical techniques, particularly through the application of robotic platforms. His most impactful work centers on demonstrating the feasibility, safety, and outcomes of robotic proctectomy for rectal cancer, as detailed in his landmark study of 71 patients from a single institution (13 citations). This work is notable for providing data from a generalizable U.S. surgeon’s practice, helping to validate robotic approaches beyond specialized academic centers. Dr. Armstrong has also been a key voice in addressing practical barriers to adoption, including a critical cost-analysis of single-incision robotic colectomy (7 citations) and an exploration of surgeon ergonomics in robotic colorectal surgery (7 citations). By tackling both clinical outcomes and the human factors of surgical practice, his contributions offer a holistic view of how robotics can reshape colorectal care. His work is essential reading for surgeons and researchers interested in the real-world integration of advanced technology into operative practice.
