Esophagogastroduodenoscopy (EGD) Description
The procedure is usually done for diagnostic purposes and permits removal of sample tissues for further study. In some cases the procedure is done to locate and remove a foreign object that has become lodged in the esophagus.
EGD is generally performed to evaluate or treat symptoms relating to the upper gastrointestinal tract, such as:
• Upper abdominal or chest pain
• Nausea or vomiting
• Difficulty swallowing (dysphagia)
• Bleeding from the upper intestinal tract
• Anemia (low blood count)
Early Cancer Diagnosis
Upper endoscopy is more accurate than x-rays for detecting inflammation, ulcers or tumors. It is used to diagnose early cancer and can frequently determine whether a growth is benign (not cancerous) or malignant (cancerous).
Recent studies have shown the usefulness of endoscopic removal of early tumors of the esophagus or stomach.
EGD is safe and well tolerated and patients are usually sedated during the exam. Hoarseness and a mild sore throat may persist for a few days after the examination.
