EGD - Esophagogastroduodenoscopy
EGD stands for Esophagogastroduodenoscopy, which is a procedure that allows a doctor to examine the lining of the esophagus, stomach, and upper part of the small intestine (duodenum). The procedure is performed using an endoscope, which is a flexible tube with a camera and a light at the end.
During an EGD, the patient is given a sedative to help them relax and feel more comfortable. The endoscope is then passed through the mouth and down the throat into the esophagus. The camera on the endoscope sends images to a monitor, which allows the doctor to examine the lining of the esophagus, stomach, and duodenum for any abnormalities or signs of disease.
An EGD can be used to diagnose a variety of conditions, including:
- Gastroesophageal reflux disease (GERD)
- Peptic ulcer disease
- Barrett's esophagus
- Celiac disease
- Gastrointestinal bleeding
- Cancer of the esophagus, stomach, or duodenum
During the procedure, the doctor may also take small tissue samples (biopsies) from the lining of the esophagus, stomach, or duodenum for further examination under a microscope.
EGD is generally a safe procedure, but there are some potential risks, such as bleeding, infection, and perforation (a tear or hole in the lining of the digestive tract). These risks are rare and the benefits of the procedure usually outweigh the risks.
