About
Ronan A. Cahill is a pioneering colorectal surgeon and researcher whose work sits at the intersection of surgical innovation, digital technology, and patient safety. His primary research areas include fluorescence-guided surgery, artificial intelligence in the operating room, and robotic surgical education. Cahill led the landmark IntAct trial (2025), the first unblinded randomised controlled trial to demonstrate that intraoperative indocyanine green fluorescence angiography can significantly reduce anastomotic leaks in rectal cancer surgery—a finding with immediate clinical impact. He has also advanced the use of computer vision and AI for real-time identification of colorectal liver metastases, achieving over 13 citations for this work. Beyond the operating table, Cahill co-authored the first international multidisciplinary consensus on reporting educational videos in robotic surgery (2020), addressing a critical gap in surgical training. His portfolio includes pioneering work on smart articulating digital devices for transanal surgery and intraoperative ureter visualization. With over 80 citations across his most influential papers, Cahill is shaping the future of surgery through rigorous clinical trials, digital innovation, and a commitment to safer, smarter operative care.
