What to expect:
At the beginning of the procedure, a local anesthetic (numbing medicine) may be applied to your throat, and your doctor may give you medication through a vein to help you relax and better tolerate any discomfort from the procedure. The procedure will begin with you lying on your left side. The scope will be passed through your mouth into the throat, stomach and small intestine. The procedure usually takes 30-45 minutes. If something abnormal is found, the physician may take a biopsy specimen or may use medication or heat treatment to stop any bleeding. Remember that biopsies are taken for many reasons and do not necessarily mean that cancer is suspected. The instrument used for the procedure will not interfere with your breathing. Because air is introduced through the tube, you may feel some bloating during and after the procedure. You may resume your usual diet uncell instructed otherwise. Your throat may feel scratchy or sore after the procedure.
For the best possible examination, you need to have a completely empty stomach. This means you will need to have nothing by mouth for at least 6-8 hours and preferably overnight before the procedure. Be sure to inform your doctor about any medication you take and the physician can direct you about which medicines you should take. You will also need to refrain from taking blood thinners or any medication containing aspirin or ibuprofen for 5 days before your procedure. If you receive any sedation, you will need for someone to take you home since it would not be safe for you to drive.
