Esophagogastroduodenoscopy (EGD)

What is an EGD?

Upper endoscopy, also known as EGD, is a procedure in which a thin scope with a light and camera at its tip is used to look inside the upper digestive tract — the esophagus, stomach, and first part of the small intestine, called the duodenum. The esophagus is a muscular tube connecting the throat with the stomach. Lined with moist pink tissue called mucosa, it measures about 8 inches long. The esophagus runs behind the windpipe and heart, and in front of the spine. The main function of the esophagus is to propel food and liquid down into the stomach for digestion. There are many diseases that can affect the esophagus, including heartburn (GERD), eosinophilic esophagitis, Barrett’s esophagus, hiatal hernia, esophageal spasm, infectious esophagitis, and cancer.

The stomach is also examined during an EGD. It’s primary job is break down food, using its natural acidic environment to aid in extracting all the nutrients that we eat. Diseases that can affect the stomach include H.pylori gastritis, pernicious anemia, gastroparesis, peptic ulcer disease, and other atypical diseases.

Lastly, the duodenum, which is the final part of the digestive tract screened during an EGD, is the first portion of the small intestine. The duodenum is about 10 in. (25 cm) long and curved, almost forming a circle. It is largely responsible for the breakdown of food, using digestive enzymes, bile, and pancreatic juice. Celiac disease and other infectious diseases can affect the duodenum.
