Esophagogastroduodenoscopy (/ᵻˌsɒfəɡoʊˌɡæstroʊˌduːoʊdᵻˈnɒskoʊpi/), 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 (unless sedation or anesthesia has been used). However, a sore throat is common.

The complication rate is about 1 in 1000. They include:

Problems of gastrointestinal function are usually not well diagnosed by endoscopy since motion or secretion of the gastrointestinal tract are not easily inspected by EGD. Nonetheless, findings such as excess fluid or poor motion of the gut during endoscopy can be suggestive of disorders of function. Irritable bowel syndrome and functional dyspepsia are not diagnosed with EGD, but EGD may be helpful in excluding other diseases that mimic these common disorders.
