Preparation
It is important not to eat or drink anything for at least eight hours before the exam. The physician instructs the patient about the use of regular medications, including blood thinners, before the exam.

The Upper GI Endoscopy Procedure
Upper GI endoscopy is usually performed on an outpatient basis. The throat is often anesthetized by a spray or liquid. Intravenous sedation is usually given to relax the patient, deaden the gag reflex and cause short-term amnesia. For some individuals who can relax on their own and whose gagging can be controlled, the exam is done without intravenous medications. The endoscope is then gently inserted into the upper esophagus. The patient can breath easily throughout the exam. Other instruments can be passed through the endoscope to perform additional procedures if necessary. For example, a biopsy can be done in which a small tissue specimen is obtained for microscopic analysis. A polyp or tumor can be removed using a thin wire snare and electrocautery

(electrical heat). The exam takes from 15 to 30 minutes, after which the patient is taken to the recovery area. There is no pain with the procedure and patients seldom remember much about it.

Results
After the exam, the physician will explain the results to the patient and family. If the effects of the sedatives are prolonged, the physician may suggest an interview at a later date when the results can be fully understood. If a biopsy has been performed or a polyp removed, the results are not available for three to seven days.

Alternative Testing
Alternative tests to upper GI endoscopy include a barium x-ray and ultrasound (sonogram) to study the organs in the upper abdomen. Study of the stools, blood and stomach juice can provide indirect information about a gastrointestinal condition. These exams, however, do not allow for a direct viewing of the esophagus, stomach and duodenum, removing of polyps or taking of biopsies.
