Dr. Karen B. Stitzenberg

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.

I am a surgical oncologist and researcher whose primary areas of focus are cancers of the liver and pancreas. As a surgeon, I believe in using minimally-invasive techniques, when possible, to speed up a patient’s recovery and get them to other avenues of care faster. My research is focused on clinical practice and clinical outcomes. I became interested in surgical oncology, because I enjoy the opportunity to restore hope to patients who may feel despair after their initial cancer diagnosis. I aim to restore hope by connecting with patients individually and providing them with options for treatment when they might feel they have none. I also work closely with my radiology oncology and medical oncology colleagues in crafting a treatment and care plan. Working together as a team often allows us to come up with a much better treatment plan than any of us could by ourselves.
