What is Upper Endoscopy (EGD)?
Also called an EGD or gastroscopy, an upper endoscopy uses a thin scope with a light and camera to look inside the esophagus, stomach, and first part of the small intestine (duodenum). A small biopsy instrument can remove tissue for microscopic evaluation.
During the exam
You receive a sedative; a local anesthetic may be sprayed to suppress the gag reflex, and a mouth guard protects your teeth. You lie on your left side while the endoscope is guided through the esophagus to the stomach and duodenum. Air is introduced to enhance viewing. The test typically lasts 10–20 minutes.
What it can find
Upper endoscopy can help determine causes of heartburn, hiatal hernia, abdominal pain, unexplained anemia, swallowing difficulty, upper GI bleeding, tumors, and ulcers.
How to prepare
The stomach must be empty. Do not eat or drink for 12 hours before the exam unless your physician gives different instructions. You may need to stop aspirin or blood thinners for several days. Arrange a responsible adult to drive you home after sedation.
