Upper GI Endoscopy (EGD)


Upper GI endoscopy, EGD (esophagogastroduodenoscopy), is a visual examination of the upper intestinal tract using a lighted, flexible fiberoptic or video endoscope.  The upper gastrointestinal tract begins with the mouth and continues with the esophagus (food tube) which carries food to the stomach.  The j-shaped stomach secretes a potent acid and churns food into small particles.  The food then enters the duodenum, or small bowel, where bile from the liver and digestive juices from the pancreas mix with it to help the digestive process.
