About
Kellie L. Mathis is a colorectal surgeon and clinical researcher whose work sits at the forefront of minimally invasive and robotic surgical techniques for colorectal disease. Based at the Mayo Clinic, Mathis has made substantial contributions to advancing robotic-assisted surgery, particularly for rectal cancer, with her landmark 2020 study demonstrating advantageous outcomes of robotic over laparoscopic approaches garnering nearly 100 citations. Her research rigorously examines operative risk factors, surgical conversion trends, and the impact of patient factors such as obesity on postoperative outcomes, helping surgeons better counsel and stratify their patients preoperatively. Among her most innovative contributions is her pioneering work on intraureteral indocyanine green to enhance ureteral visualization during complex robotic colorectal procedures — a practical patient safety advancement cited 70 times and addressing a historically underappreciated complication risk. Mathis has also investigated rare conditions including presacral tailgut cysts, drawing on Mayo Clinic's extensive multi-site experience to clarify malignancy risk and surgical management. Across her portfolio, spanning Crohn's disease, super obesity, and national surgical trends, her research consistently bridges technical innovation with meaningful clinical outcomes, making her an influential voice in contemporary colorectal surgery.
