You may be accompanied by one adult family member or friend. Children should not accompany adults having any procedures. Because you are not permitted to drive after your procedure, an adult must accompany you to take you home. A responsible adult should stay with you the night following your procedure. Children scheduled for a procedure should be accompanied by two adults, one to assist the child and one to drive home.

When you arrive at the hospital on the day of your procedure report directly to the 4th floor M building and sign in at desk. You will be called to your room. You will be given a hospital gown to wear. You will be asked to remove dentures, hairpieces or hair pins, artificial limbs and contact lenses. You will be asked to remove nail polish and makeup if you didn’t already do it at home. Any jewelry that you wear to the hospital such as a wedding band must be given to your family member or friend. Please remember to remove all body piercings.

You will be interviewed by a registered nurse who will do a nursing assessment, document your historical information and verify all medications (both prescribed by a physician and over the counter) that you are taking and the last time you took each of your medications. Please bring a list of all your medications, including over the counter medication, herbs, vitamins and supplements. Include the name, dose and how often you are taking each item. You will have an Intravenous (IV) line inserted and be given IV fluids.

If you are pregnant or think you might be, or if you are breast-feeding, tell the doctor and technologist before your test.

Healthcare professionals will be available in this area to make you comfortable and to answer your questions. The staff may ask you the same questions several times. They will ask your name, what procedure you are having done, your medications and your allergies. By repeating our questions, we are verifying and re-verifying very important information to ensure that your time with us is as safe as possible. This is a double check system to ensure your safety which is our number one priority.

You will be seen by your physician who will ask you to sign a consent form. This legally permits your physician to perform your procedure.

During the Procedure

You will be taken to procedure room on the same cart and positioned on your left side for either the colonoscopy or sigmoidoscopy. You will draw your knees up to your chest.

You will be attached to a cardiac monitor and your blood pressure will be taken. You may have an oxygen mask or oxygen prongs in your nose. The people around you in the room will be preparing for your procedure. The registered nurse will always be in the room with you, and staff will stay by your side and will explain everything that is happening.

You will be given moderate, twilight sedation and/or pain medication through the IV line to relax you and keep you comfortable. You may either be drowsy or completely asleep. Many patients do not remember having the colonoscopy. You will be continually monitored and made as comfortable as possible.

The test will be performed by the physician. A rectal exam is done to check for any anal or rectal problems. The rectum is lubricated. The gastroenterologist then inserts a long, flexible lighted tube called a colonoscope into the anus. This tube is four foot long and about the width of a finger. A small camera is mounted on the scope and transmits an image to a computer screen. The scope is slowly guided through the rectum into the colon as the physician carefully examines the intestinal lining.

If you are awake you may feel like you have to have a bowel movement. Air is pumped into the colon to give the physician a better view. This may cause you to feel some cramping or gas pains. It is okay to pass gas during the procedure. You can also reduce discomfort by taking slow, deep breaths. This will also help relax your abdominal muscles.

Once the scope reaches the opening of the small intestine it is slowly withdrawn. The physician carefully examines the lining of the intestine again.

Tiny tools can be passed through the scope to perform a variety of functions. Suction can be used to remove fluid or stool. The doctor can remove growths, called polyps with electorcautery snares. Abnormal tissue samples can be taken with biopsy forceps. Photographs may be taken. If any bleeding occurs it is treated with an electrical probe to cauterize the area or special medication passed through the scope. This is generally a painless procedure. The polyps or tissue is then sent to a pathology lab to be tested for signs of cancer.

The procedure takes 30 to 60 minutes or longer.

The sigmoidoscopy is slightly different. The prep may be slightly different as only the lower part of the colon needs to be cleansed. You may be instructed to use enemas or laxatives. Please make sure you follow the physician’s instructions. A sigmoidscope is used. It is about two foot long and the width of your little finger. This shorter thin flexible tube is only passed through the anus to the lower part of the colon called the sigmoid colon. The procedure takes about 20 minutes.

After Your Procedure

After your procedure you will be taken to the recovery area. The physician will explain the results of the test to your family. During this time you will awaken from sedation.The nurse will continue to monitor your vital signs; blood pressure, pulse, temperature, and your breathing.

When you wake up you may feel some cramping or bloating from the air that was introduced through the scope. This occurs more frequently during the first hour after the procedure. You may pass a lot of gas. The sedative may take a couple hours to completely wear off. You may not feel any discomfort or remember the procedure. You will be given something to drink and may resume your regular diet when you return home. Try to avoid anything with a red or purple color for a few days.

After you are recovered from the sedation, your vital signs (blood pressure, pulse, respiration and temperature) are stable and you are comfortable, your IV will be removed. You will be seen by your physician, and given discharge instructions. In order to be discharged from the GI Lab you must have a driver because of the sedation you received.

Your time in the GI Lab will vary depending on the procedure you had done, how well you are doing and how comfortable you are. It will be approx 2.5 hours.

You should notify your physician immediately if you develop any of these rare side effects:
• Fever of 100.4°F or greater
• Severe abdominal pain
• Bloody bowel movements
• Dizziness
• Weakness

Thank-you for allowing us to care for you during your GI Lab procedure.
