The Division of Gastroenterology and Hepatology at Mayo Clinic's campus in Rochester, Minnesota, 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. In any given year, members of the division perform approximately 36,000 to 40,000 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 of Mayo Clinic's recognition 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, including extensive endoscopic research efforts.

The gastrointestinal endoscopy group within the Division of Gastroenterology and Hepatology offers a full array of diagnostic and therapeutic procedures. Each year, the Mayo gastrointestinal endoscopy practice performs 1,600 to 1,700 ERCP procedures, 2,500 EUS procedures, and similar numbers of other complex endoscopic procedures.
