What is upper endoscopy (EGD)?
Upper endoscopy allows your doctor to exam the lining of the upper part of your gastrointestinal tract, which includes the esophagus, stomach, and the first portion of the small intestine called duodenum. Upper endoscopy is performed to evaluate symptoms such as upper abdominal pain, nausea, vomiting, and celiac disease. Your doctor may also obtain biopsy to roll out any abnormalities for ulcer or malignancy.
What preparation is required?
You should not eat or drink anything for six hours prior to your upper endoscopy. An empty stomach allows for the best and safest examination. You should avoid aspirin products, arthritis medications, iron supplements, anti-coagulants and anti-platelet medications 4-5 days prior to your procedure or as directed.
What to expect during procedure?
Your doctor will start by spraying your throat with a local anesthetic and follows by giving you a sedative to help you relax. Then you will lie on your side, and the doctor will pass the endoscope through your mouth and into the esophagus, stomach and duodenum. Most patients fall asleep during the procedure. Your doctor will biopsy any abnormal areas and these will be sent for further pathology examination.
What can I expect after the procedure?
You will be monitored closely until the effects of the sedation have worn off. You might experience a sore throat and bloating after the procedure. Once you recover from the effect of the sedation, you will be released. However, a responsible adult driver needs to take you home. Discharge instructions should be carefully read and followed.
