An upper GI (Gastrointestinal) endoscopy or EGD (esophagogastroduodenoscopy) is an outpatient procedure in which your doctor uses an endoscope, a flexible tube with a camera to see the lining of your upper GI tract. The upper GI tract includes your food pipe (esophagus), stomach, and the first part of your small intestine (duodenum). It is carried out to identify disorders of your upper GI tract such as GERD (gastroesophageal reflux disease), ulcers, precancerous and cancerous lesions, strictures or narrowing of esophagus etc.
