The Division of Gastroenterology and Hepatology at Mayo Clinic specializes in the prevention, diagnosis and treatment of diseases of the digestive tract and liver. It is the largest practice of its kind in the United States. Each year, members of the division perform approximately 48,000 endoscopic procedures in state-of-the-art facilities using the latest equipment.

The division is organized around interest groups oriented toward disease processes, organ systems, procedures or patient groups. Clinical expertise is integrated with the newest forms of established and experimental diagnostic and therapeutic methods.

Patient care is provided by teams of physicians and other health care staff with broad expertise in all forms of gastroenterological and hepatobiliary diseases. Because we recognize that high-quality care depends upon scientific discovery, major research programs at the basic, applied and translational levels exist to generate new knowledge that ultimately improves patient care.

Among the areas of clinical and research expertise offered in gastroenterology are:

  • Anorectal function testing and evaluation of constipation and fecal incontinence
  • Barrett's esophagus and esophageal cancer, including therapy with endoscopic mucosal resection and photodynamic therapy
  • Clinical nutrition with emphasis on malabsorption and malnutrition from gastrointestinal diseases
  • Diagnostic and therapeutic endoscopy, including enteral stents, biliary stents, banding of esophageal varices, small bowel capsule enteroscopy, endoscopic treatment for gastrointestinal bleeding, endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound, single- and double-balloon assisted endoscopy, endoscopic treatment of obesity and metabolic disease, and endoscopic revision of bariatric surgery
  • Diseases of the pancreas, including acute and chronic pancreatitis, autoimmune pancreatitis, hereditary pancreatitis, pancreatic cancer, pancreatic cysts, adult cystic fibrosis
  • Gastrointestinal and hepatobiliary cancers
  • Heartburn and gastroesophageal reflux disease (GERD), including endoscopic anti-reflux procedures
  • Hepatobiliary disease and liver transplantation
  • Inflammatory bowel disease, including Crohn's disease and ulcerative colitis
  • Motility disorders and motility testing, including radionuclide gastric and intestinal transit studies, 24-hour pH monitoring, gastroduodenal motility, and ambulatory motility recordings
  • Swallowing disorders and noncardiac chest pain


In addition to caring for patients in clinical practice, Mayo Clinic's faculty is committed to teaching and facilitating the growth of medical knowledge. Many of our faculty members have published and lectured extensively and are highly regarded in their fields.

You have direct access to the gastroenterology and hepatology faculty at Mayo Clinic throughout your training in the Gastroenterology Fellowship.

Advisers and mentors

You are assigned a dedicated faculty adviser who can provide comprehensive educational advice and personal support. You meet with your adviser periodically throughout the program to review your progress and career goals, and ensure that your educational needs are being met. Also, your adviser may serve as a contact point for introducing you and your family to Rochester, Minnesota, and the Mayo Clinic system.

Visiting professors

Many prominent professors visit Mayo Clinic each year. They present their work during lectures, participate in hospital rounds and have informal discussions with trainees. You are encouraged to take full advantage of these educational opportunities.
