This procedure is an endoscopic examination of the colon by a physician. A thin, flexible tube with a video camera at the tip is used to examine the colon. If necessary, a small piece of tissue (biopsy) can be removed for further examination under a microscope. If a polyp is found, it can generally be removed during the procedure. You will be given an intravenous line (I.V.) in the holding area. Immediately before the procedure begins you will receive I.V. medication for sedation. The test will take approximately 30 minutes to complete. You will be returned to the recovery area where you will be monitored for at least one hour after the procedure. Every effort will be made to keep your appointment at the scheduled time, but in medicine, unexpected delays and emergencies may occur and your wait time may be prolonged. We give each patient the attention needed for his or her procedure.

  • You may not drive, operate machinery, make important decisions, or return to work for the remainder of the day following your procedure. You may resume normal activities the next day unless the doctor states otherwise.

  • You must have a responsible adult to accompany you home after the procedure. This person must pick you up in the GI Lab. If you have another Doctor’s appointment or any other testing at Northwestern Memorial Hospital after your GI Lab procedure, a responsible adult must escort you out of the GI Lab and to your appointment.

  • You may not walk, take a taxi, or any public transportation home unless you are accompanied by a responsible adult.

  • If our staff cannot confirm that you have made safe plans for discharge after your procedure, your procedure will be cancelled.

  • If you will need assistance getting home after your GI Lab procedure, you can arrange a ride home with Illinois Medi Car through Superior Ambulance Company by calling 312-926-5988 or 312-832-2000. The service area from the hospital is North to 5600 Bryn Mawr Ave, West to 2400 Western Ave, and South to 47th St. If you have made Illinois Medi Car arrangements for your discharge home, please inform the GI Lab staff on the day of your procedure.

If you are required to pre-certify your procedure with your insurance company, please make certain that you have done so in advance. You should also double check that both Dr. Cohen and Northwestern Memorial Hospital are in your insurance network. If your insurance company requires you to have a referral for your procedure, please bring it with you on the day of your procedure. If you have Medicare, an Advance Beneficiary Notice (ABN) will be presented to you. This form acknowledges that Medicare may deny payment for the colonoscopy which could cause you to become responsible for the cost of the procedure. Please contact Medicare directly with further questions 800-633-4227.
If you are affected by any of the conditions listed below, please follow these instructions carefully.


Check with your physician regarding your dose of insulin and other diabetic

medications needed the day before and the day of your procedure. Inform your

doctor that you will be on clear liquids the day prior to your procedure. Check your

blood sugar frequently while taking the prep solution and the morning of your procedure.

Heart Valve Replacement

Prophylactic antibiotics are no longer recommended for GI procedures according to the guidelines published by the American Heart Association in 2007.

Blood Thinners:

Coumadin, Plavix, Pradaxa, Xarelto, Eliquis, Brilanta, Effient, Lovenox

Ask the physician who prescribed your medicine how to take it before and after

your procedure. If you cannot contact your physician, call us several days

before your exam. If you take Coumadin, you may need a blood test two

hours before your exam.

Iron Supplements

It is desirable that iron supplements be held for five days prior

to your procedure.


Although colonoscopy is a safe test, there are inherent risks with all medical procedures. These risks include, but are not limited to: 1) Risk of anesthesia reactions including cardiopulmonary complications. 2) Bleeding. 3) Perforation or puncture of the colon a rare complication that occurs once in every several thousand procedures. 4) Possibility of an incomplete exam in 1-2% of patients. 5) Possibility of missed or incompletely removed polyps. Although colonoscopy is the best test for detection and removal of polyps, it is not perfect. It is possible for polyps to be missed.


For best outcome, avoid eating foods that contain seeds, nuts, hulls, berries, or kernels (such as popcorn, poppy seeds, tomatoes, cucumbers, etc.). However, this instruction is not critical.


If you are constipated (i.e. bowel movements every 2-3 days or longer), it is recommended that you drink 10 ounces of Magnesium Citrate laxative two days before the colonoscopy so that the preparation on the day before the colonoscopy is easier and more effective. Magnesium Citrate is available without a prescription at any pharmacy. If you have kidney problems or are on dialysis, do not take Magnesium Citrate.


  1. Today you may not eat any solid foods. You are to drink only CLEAR LIQUIDS all day long.

Clear Liquids include: water, coffee or tea without milk, strained fruit juices without pulp (apple, white grape, cranberry, etc.), carbonated beverages or soda pop, clear broth or bouillon. You may have plain Jello or Popsicles except for any red in color. You may have clear hard candy. If you are diabetic, please follow your usual dietary restrictions with regard to the liquids listed above.

    1. Drink one 8 ounce serving of clear liquids EVERY HOUR from the time you rise until you start the HalfLytely at 5 p.m.

    2. Between 4 p.m. and 6 p.m. (as early as possible) take 1 bisocodyl delayed-release tablet with water (this is included in the HalfLytely kit). Do NOT chew or crush the bisacodyl tablet. Do not take the bisacodyl tablet within 1 hour of taking an antacid. You will likely need to go to the bathroom within 1-3 hours of taking the bisocodyl delayed-release tablet.

    3. If you are scheduled for a morning colonoscopy: Between 8 p.m. and 10 p.m. (approximately 2 hours after taking the bisacodyl tablet) begin to drink HalfLytely, 8 ounces every 15-20 minutes until the entire 2 liters are consumed. Then drink two 8 ounce glasses of any clear liquid.

If you are scheduled for an afternoon colonoscopy: Between 8 p.m. and 10 p.m. (approximately 2 hours after taking the bisacodyl tablet) drink four 8 ounce glasses of HalfLytely, 1 glass every 15-20 minutes, followed by two 8 ounce glasses of any clear liquid. On the morning of your colonoscopy, about 5-6 hours before the procedure, drink four more 8 ounce glasses of HalfLytely, 1 glass every 15-20 minutes, followed by two 8 ounce glasses of any clear liquid.

d. In order to perform a successful colonoscopy, the colon must be cleaned of fecal material. This is accomplished using this preparation and will stimulate your colon to purge itself, and result in many trips to the bathroom. You will probably start to have a bowel movement within 1 to 2 hours of taking the laxative. The laxative may cause rapid elimination of stool.

  1. Do not eat or drink anything after Midnight.

If your test is scheduled for the afternoon, you may have clear liquids up to 3 hours before the test.

  • You may take your usual medications with small sips of water. If you use inhalers, prescription eye drops or nasal sprays, you may take them as you would normally and then bring them with you.

You will be asked to put on a hospital gown. An intravenous line (IV) will be started for your sedation during the procedure. If you are female, you will be offered a free pregnancy test prior to the procedure, per hospital policy. If you have a history of falling or fainting, please tell the nurse before the IV is placed.

    You may be waiting in a gowned waiting room prior to your procedure with other patients. There are many doctors that perform procedures in the GI Lab and many patients that are having a variety of procedures. If you have any concerns about a delay or your exact procedure time, please speak with one of the GI Lab staff members.

  • During the procedure, your heart rate, blood pressure and oxygen level will be monitored.

  • You will be required to sign a consent form with the doctor prior to your procedure.

  • When your procedure is done, you will remain in the recovery room for at least 1 hour.

  • You may still experience effects from the sedation, such as being tired and forgetful, for a few hours after your procedure.

  • The recovery room nurse will review what you should expect to feel for the remainder of the day. If you had a colonoscopy, this includes feeling some gas pain. If you have had an upper endoscopy, you may have a sore throat.

  • After the procedure, you will receive preliminary results and follow-up instructions.

  • When you leave the GI Lab, please remember to take all of your belongings and your discharge instructions.
