Upper endoscopy is the examination of the lining of the upper part of your gastrointestinal tract that includes esophagus, stomach and duodenum (beginning of your small intestine) using a thin, flexible tube called endoscope which has a video camera and a light source.
Dr Kethu performs upper endoscopy if you’re being evaluated for symptoms of abdominal pain, acid reflux, nausea, vomiting, difficulty swallowing, chronic bleeding, and anemia. Sometimes biopsy samples are taken to look under the microscope to rule out infection, cancer, etc.
You need to fast after midnight before the upper endoscopy. Empty stomach allows the best and safest examination..
Dr Kethu may ask you to stop some medications temporarily, particularly aspirin products, or blood thinners, insulin or iron products.
You will be given sedation to perform this procedure comfortably without any pain or discomfort. While you are asleep, an endoscope is passed through the mouth gently into the upper gastrointestinal tract. The endoscope doesn’t interfere with your breathing.
You will be monitored closely until most of the effects of the medications have worn off. You cannot drive yourself to home after the procedure. You need someone to pick you up. You can resume most of the normal activities after the procedure. You may have some sore throat. You can resume normal food intake unless instructed otherwise.
Upper endoscopy is generally a very safe procedure. Like any medical procedure complications can happen although very rare. Bleeding can occur at the biopsy site or when polyp is removed. Perforation (whole or tear in the lining of the gastrointestinal tract) may require surgery. Some patient’s may have breathing or heart problems secondary to sedation.
