An esophagogastroduodenoscopy (EGD) is an outpatient procedure that is used to examine your esophagus, stomach, and the first part of your small intestine (called the duodenum). An EGD is sometimes called an upper endoscopy because it is used to evaluate the condition of your upper gastrointestinal tract.
What is an EGD? An EGD is a test that allows your doctor to look at your esophagus, stomach and duodenum (upper part of the small bowel). He or she would like to do an esophagogastroduo - denoscopy (EGD). This test is sometimes called an upper gastrointestinal (UGI) endoscopy. For this test your doctor will use a flexible lighted tube called an endoscope.
