Gastroscopy - and more specifically esophagogastroduodenoscopy (EGD) - is an endoscopic (i.e. inside the body) examination of the upper gastrointestinal tract, which allows for the assessment of the esophageal mucosa, stomach and proximal duodenal segment, and, if necessary, performing procedures in this area.
