A registered nurse specially trained in assisting with gastroenterology procedures, CPR and Advanced Cardiac Life Support will take you to the procedure room and stay with you for the entire test. The room can be very intimidating. It is crowded with medical equipment and has strange sounds. Your vital signs will be monitored closely, and you will wear oxygen for the test.
The doctor will speak with you before the test. He will discuss your medical history and symptoms. Again, feel free to ask any questions. You will sign a consent for the examination.
If you are having an EGD you will have to remove any partial denture or plates. When the doctor is ready, you will turn to your left side and the RN will start your sedation. You should feel very sleepy or maybe euphoric quickly. Once you are sedated the test will begin. An EGD and flexible sigmoidoscopy usually lasts 5-15 minutes, and a colonoscpy can last from 15-30 minutes. An ERCP and EUS can take an hour or longer. Usually you wake in recovery with no recollection of the test.
Manometries, acid reflux tests and capsule endoscopies take up to an hour. No sedation is given for these tests. Capsule endoscopies require a return visit in 8 hours. Acid reflux tests require a return visit either in 24 or 48 hours, depending on the type of test you have.
