what is egd in medical terms

EGD stands for esophagogastroduodenoscopy, which is a medical procedure used to examine the lining of the esophagus, stomach, and first part of the small intestine (the duodenum) . During the procedure, a flexible tube with a camera on the end is passed through the mouth and down the throat to visualize the upper gastrointestinal tract. EGD is primarily a diagnostic procedure, but it can also be used therapeutically to treat problems that are found during the exam. The test is done in a hospital or outpatient center and is generally a safe and well-tolerated procedure.
