Gastroenterology
Gastroenterology involves the diagnosis and treatment of digestive system disorders affecting the esophagus, stomach, small and large intestines, rectum, liver, gall bladder and pancreas. Gastroenterologists receive dedicated training in endoscopy, which is the use of narrow, flexible lighted tubes with built-in video cameras, to visualize the inside of the intestinal tract. Gastroenterologists are taught to evaluate patients with gastrointestinal complaints, treat a broad range of conditions, and provide recommendations to maintain health and prevent disease.
