upper endoscopy, sometimes referred to as esophagogastroduodenoscopy (EGD), is a procedure performed by a physician and involves placing a tube with a light (called an endoscope) through the mouth into the esophagus, stomach, and duodenum. It has a small camera that allows the operator to view the upper gastrointestinal tract, which is magnified on an outside viewing monitor. The endoscope can be fitted with surgical instruments to allow the operator to perform procedures or obtain tissue samples for biopsy |

the gastrointestinal tract is responsible for digestion, absorption, and elimination of food. It is divided into “upper” and “lower” sections beginning with the mouth and ending with the anus. The main structures of the upper gastrointestinal tract include the mouth, pharynx, esophagus, stomach (gastrum), and duodenum. The lower gastrointestinal tract includes the jejunum, ileum, colon, rectum, and anus |
