Gastroenterology is the diagnosis and treatment of disorders and diseases of the stomach, small intestine and large intestine (colon), and related structures such as the esophagus, liver, gallbladder and pancreas.

FHN gastroenterologists treat a broad range of conditions and perform procedures including endoscopic (scope) examinations of the esophagus, stomach, small and large intestines, pancreas, gallbladder, liver and common bile duct. These procedures are performed under moderate sedation, using a flexible scope with a camera lens which allows the physician to view the organs' inner lining. During the procedures, specialized instruments are used to take biopsies, remove polyps, cauterize bleeding sites and dilate strictures.

Other common gastroenterological procedures include placement of feeding tubes, treatment of hemorrhoids, capsule endoscopy to non-invasively examine the small intestine and pH and motility studies.
