Expertise and rankings

Experience

Each year, Mayo Clinic doctors diagnose and treat more than 5,000 adults and children with Crohn's disease. Mayo specializes in helping people with severe symptoms that haven't responded well to treatment in the past.

Advanced diagnosis methods

Mayo Clinic researchers helped develop noninvasive imaging techniques that make it possible for doctors to thoroughly inspect the small bowel, such as MR and CT enterography. These tests are more sensitive than conventional imaging for finding inflammation, pockets of bacterial infection (abscesses) and abnormal tunnels that develop between loops of intestine or between the intestine and other organs (fistulas).

Mayo Clinic doctors also use balloon-assisted enteroscopy to look for sources of bleeding that can't be found by other methods. During this procedure, a scope and an overtube with one or two attached balloons are inserted through your mouth or anus into your digestive tract. This method allows for deeper insertion and visualization of your small intestine.

Doctors may also use endoscopic ultrasound, which involves examining the intestinal wall with an ultrasound probe. This method is helpful for finding fistulas and looking for complications such as abscesses in the perianal area.

Research

Mayo Clinic doctors conduct research in new diagnostic tests and treatments for Crohn's disease and conduct clinical trials. Mayo's Center for Cell Signaling in Gastroenterology (C-SIG) focuses its research on mechanisms of cellular and molecular processes in a variety of digestive diseases, including Crohn's disease.
