Question: what is the difference between an upper gi series and an endoscopy?
Answer: By tradition, "endoscopy" or "upper GI endoscopy" refers to the examination of the upper gastrointestinal tract: the esophagus, stomach, and duodenum. The correct term is esophagogastroduodenoscopy (EGD), so you can see why we stick with "upper GI endoscopy."
