Procedures

Gastroenterologists order and perform many types of diagnostic procedures. The most-common are colonscopy and EGD.

Colonoscopy allows the gastroenterologist to look inside the entire large intestine, which includes the rectum and colon. It uses an instrument called a colonoscope, which has a camera attached to the end of a long, flexible tube that is the width of an index finger. The physician views images from the scope on a monitor. The walls of the large intestine are thoroughly inspected for abnormalities such as inflamed or bleeding tissue, and polyps. Small samples of tissue are taken for examination. If a polyp is found, it will be removed and checked for cancer cells.

EGD is short for esophagogastroduodenoscopy. It is a test in which the gastroenterologist thoroughly inspects the inside of the upper digestive tract using a flexible instrument called an endoscope that is about the diameter of an index finger. A camera at the tip of the endoscope allows the physician to see the esophagus, stomach and first part of the small intestine to determine the cause of symptoms to explain the results of X-rays or other diagnostic tests.
