What does EGD stand for?

Esophagogastroduodenoscopy

Esophagogastroduodenoscopy, also called by various other names, is a diagnostic endoscopic procedure that visualizes the upper part of the gastrointestinal tract down to the duodenum. It is considered a minimally invasive procedure since it does not require an incision into one of the major body cavities and does not require any significant recovery after the procedure.
