Clinical Specialties

Dr. Kennedy is certified by the American Board of Colon and Rectal Surgery and by the American Board of Surgery. In addition, he is a Fellow of the American College of Surgeons (FACS) and a Fellow of the American Society of Colon and Rectal Surgery (FASCRS). Dr. Kennedy’s main interest is in laparoscopic approaches to complex colorectal disease. He has experience with all advanced laparoscopic and minimally invasive approaches including single incision laparoscopy and robotic surgery. His clinical areas of expertise include: colon cancer, rectal cancer, inflammatory bowel disease, benign conditions of colon, rectum, and anus, and endoscopic treatment of colonic disease.

Operations that are laparoscopically performed include: sphincter preserving surgery for rectal cancer, abdominoperineal resection for rectal cancer, total and partial colon resection, restorative proctocolectomy for ulcerative colitis or prophylactically for familial cancer syndromes. Dr. Kennedy also provides the spectrum of colon and rectal surgical procedures including abscess drainage, fistulotomy, and hemorrhoidectomy.

Research Interests

Dr. Kennedy’s funded laboratory effort is focused on chemoprevention of colon and rectal cancer. His laboratory uses genetic models to better understand how chemicals prevent tumor formation and what genetic pathways are responsible for their effects. The ultimate goal of this effort is to identify targeted agents that are better tolerated by patients in hopes of preventing colon and rectal cancer.

In addition to a basic laboratory research program, Dr. Kennedy is interested in quality improvement research. His research focuses on gaining a better understanding of postoperative complications. Our hope is that by understanding the types of complications and their timing we can start to better anticipate complications and ultimately prevent them. Our prevention work uses systems approaches to improve the quality of our patient care. Through these approaches we have dropped our rate of wound complications and seen our length of stay shortened.
