Upper Endoscopy

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.

Usually performed as an outpatient procedure, upper endoscopy sometimes must be performed in the hospital or emergency room to both identify and treat conditions such as upper digestive system bleeding.

The procedure is commonly used to help identify the causes of:

  • Abdominal or chest pain
  • Nausea and vomiting
  • Heartburn
  • Bleeding
  • Swallowing problems
  • Endoscopy can also help identify inflammation, ulcers, and tumors

Upper endoscopy is more accurate than X-rays for detecting abnormal growths such as cancer and for examining the inside of the upper digestive system. In addition, abnormalities can be treated through the endoscope.
