Why have you been scheduled for an endoscopy?

Upper endoscopy usually is performed to evaluate possible problems with the esophagus, stomach or duodenum, and evaluate symptoms such as upper abdominal pain, nausea or vomiting, difficulty in swallowing, or intestinal bleeding anemia. Upper endoscopy is more accurate than X-ray for detecting inflammation or smaller abnormalities such as ulcers or tumors within the reach of the instrument. Its other major advantage over X-ray is the ability to perform biopsies (obtain small pieces of tissue) or cytology (obtain some cells with a fine brush) for microscopic examination to determine the nature of the abnormality and whether any abnormality is benign or malignant (cancerous).

Biopsies are taken for many reasons and may not mean that cancer is suspected. Upper endoscopy also can be used to treat many conditions within its reach. The endoscope's channels permit passage of accessory instruments enabling the examiner to treat many of the conditions such as stretching areas of narrowing (strictures, Schatzki ring), removal of benign growths such as polyps, retrieving accidentally swallowed objects, or treating upper gastrointestinal bleeding, as seen in ulcers tears of the lining. These capabilities have markedly reduced the need for transfusions or surgery
