Dr. Billy Y. Lan

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 Ureteroscopy.

As a colorectal surgeon, I specialize in the surgical management of a wide array of problems involving the small intestine, colon, rectum, and anus. My patients may be dealing with cancer or a variety of benign diseases including diverticulitis, inflammatory bowel disease or anorectal problems. I utilize minimally invasive techniques including robotics, laparoscopy, endoscopy, and transanal surgery. My primary focus is on ensuring that patients receive high quality, compassionate care while optimizing patient outcomes. My research interests include improving patient outcomes after colorectal surgery and quality improvement. Dr. Sherman is rated as an Advanced provider by MediFind in Ureteroscopy. Her top areas of expertise are Familial Colorectal Cancer, Colorectal Cancer, Crohn's Disease, Bladder Reconstruction, and Ureteroscopy.

I’m a fellowship-trained surgical oncologist who specializes in the surgical management of patients with gastrointestinal malignancies—including soft tissue sarcomas and pancreas, colorectal and gastric cancers. Many of my patients have advanced malignancies and I am always amazed at their resilience. Their determination to fight inspires me to aggressively pursue every surgical option and to study novel techniques to improve surgical outcomes. One of the most important reasons for patients to be treated at Duke is the emphasis on a team-oriented approach to every patient. Nearly every surgical cancer patient is discussed in a multidisciplinary tumor conference in order to assure state of the art care. When I am not in the hospital, my wife and I can be found chasing our two young children or running with our dog. Dr. Blazer-Iii is rated as a Distinguished provider by MediFind in Ureteroscopy.
