EGD

EGD: A diagnostic test used to aid in identifying abnormalities of the esophagus, stomach, and small intestines.   Abnormalities such as: esophagitis, inflammatory bowel disease, ulcers, tumors, gastritis, and polyps.

During an EGD, a flexible fiberoptic tube is passed through the mouth and throat into the upper digestive tract.

Esophagus:  Extends from the pharynx to the stomach.  It is approximately 9-9.75 inches long.  The esophagus is responsible for carrying food and liquids from the mouth to the stomach.

Stomach: A sac-like portion of the digestive tract located between the esophagus and the small intestine.   The stomach helps digest food which is then released into the small intestine.

Duodenum:  The first portion of the small intestine.  It is approximately 2-2 1/2 inches long and starts at the lower stomach and extends to the Jejunum.

Esophagitis: Inflammation of the esophagus.  Associated with a hital hernia or duodenal ulcer.  It can be caused by reflux of gastric or duodenal contents.

Gastritis: Inflammation of the stomach.  Symptoms include epigastric pain, tenderness, nausea, and vomiting.   Gastritis may result from infection, alcohol, or dietary changes.

Peptic Ulcer: An ulcer of the mucosa of the stomach or duodenum.  The ulcer lesion is depressed, red, and inflamed.  If the ulcer becomes infected pus is present and discharged giving a white appearance.   There are various types of ulcers of the stomach and duodenum.  Peptic ulcers are caused by the effects of gastric acid and pepsin.

An EGD involves several steps before and during the procedure.

Preparation: You will be asked not to drink or eat anything after midnight the night before your test.

Sedation: You will be given I.V. medication to help relax you and prevent discomfort during the procedure.

What to expect:  The procedure usually takes from 30 minutes to one hour.  The I.V. medication will cause drowsiness following the procedure.  You will be asked to have a family member or friend drive you home.
