About
Deborah S. Keller is a leading colorectal surgeon and researcher whose work sits at the intersection of minimally invasive surgical innovation, oncologic outcomes, and evidence-based practice guidelines. Her research has substantially advanced understanding of robotic and laparoscopic approaches to colorectal surgery, with particular focus on comparative effectiveness, provider volume relationships, and patient-specific factors such as BMI. Her early comparative studies on robotic versus laparoscopic colorectal resection, accumulating nearly 100 citations, helped define the clinical landscape during a pivotal period of technological adoption. Keller has also contributed meaningfully to rectal cancer care, investigating national disparities in minimally invasive surgery use among older adults and identifying predictors of positive circumferential resection margins — critical determinants of local recurrence and survival. As a contributor to the American Society of Colon and Rectal Surgeons Clinical Practice Guidelines for Crohn's Disease, her influence extends beyond the operating room to shape national standards of care. Her more recent prospective work on single-port robotic colorectal surgery signals continued commitment to pioneering emerging platforms. With hundreds of citations across her portfolio, Keller remains an influential voice driving surgical precision, equity, and innovation in colorectal care.
