Gastroenterologist Jacksonville, FL Areas of focus: Colonoscopy, Upper endoscopy, Chromoendoscopy, Ulcerative colitis, Crohn's disease, Pouchitis, Gastrointestinal bleeding ResearchMayo Clinic researchers are working to improve diagnosis and treatment of Crohn's disease. Radiologists at Mayo Clinic were instrumental in developing novel bowel imaging techniques, including magnetic resonance (MR) and CT enterography. Current research to refine and enhance minimally invasive intestinal surgery could benefit people with Crohn's disease in the future. Doctors at Mayo Clinic also are actively exploring new biological therapies to help manage Crohn's disease. Some investigators are studying possible links between diet, the immune system and bacteria in the digestive tract, called the microbiome. Other research focuses on the genetic basis of Crohn's disease. Clinical trials are ongoing for a new bioprosthetic plug that has been proposed for the treatment of complex anal fistula.

The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
