Overview
I am a cancer surgeon who specializes in treating patients with pre-cancerous and cancerous conditions of the pancreas, liver, bile ducts, stomach, and adrenal glands. I initially trained and practiced at Walter Reed Army Medical Center in Washington, D.C. During this time, I served one year on a forward surgical team in Iraq. Following this service, I practiced for 13 years as a surgical oncologist at Memorial Sloan Kettering Cancer Center in New York. In 2018, I joined the faculty at Duke University and now serve as the chief of surgical oncology for Duke Health. I enjoy getting to know my patients and delivering the highest quality of cancer care. I am dedicated not only to treating and curing your cancer, but also providing you with the highest quality of life. Operations for cancers within the abdomen are a serious undertaking, and I am committed to making sure that they are performed with the highest level of expertise.

Duke Ambulatory Surgery Center
I am a colorectal surgeon and researcher who has been at Duke for about 25 years. I see patients who have issues with the small bowel, colon, rectum and anus. These issues include benign tumors, cancers, hemorrhoids and fistulas. The best part of my job is operating. The operating room is a special place, where we have been able to put a number of processes in place so things run smoothly and we can give patients the best chance at a good outcome. The fact that you can take a condition, operate and potentially cure a patient is fascinating to me. As a faculty member, I also enjoy when I have the chance to teach residents during the operation. When I am not at work, I enjoy fishing, hiking and playing tennis with my children. Dr. Mantyh is rated as a Distinguished provider by MediFind in the treatment of Colorectal Cancer.
