A flexible tube with a camera less than 10 mm in diameter, the approximate size of a tylenol, is put into the esophagus, stomach and a small portion of the small bowel by a trained physician. Sedation is usually given to relax the patient and decrease any anxiety and fear. The patient is watched closely during the procedure including routine check of the blood pressure, heart rhythm, heart rate and respirations. This procedure can take up to 20 minutes to perform.
The patient will usually be without food or drink for at least 6 hours prior to the test. Most often, the physician holds food and drink after midnight the night prior. Hospital stay is approximately 2 hours from the time the patient arrives in the Endoscopy Center waiting room until completion of the procedure.
