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 Gastrointestinal Fistula.

I’m a general surgeon that specializes in operating on the upper abdomen as well as treating complicated abdominal wall problems like large hernias. The benefits of getting treatment at Duke are the extensive resources available that providers like myself can use. When necessary, we collaborate with other specialists and research experts at Duke in a seamless way, so the patient will get the benefit of all that we have to offer. Outside of work, I enjoy spending time with my wife and our three daughters. Dr. Pappas is rated as a Distinguished provider by MediFind in the treatment of Gastrointestinal Fistula.
