ABOUT THE COLONOSCOPY
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

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.
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. 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-

RISKS OF COLONOSCOPY
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.
ONE WEEK BEFORE YOUR COLONOSCOPY
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.
TWO DAYS BEFORE YOUR COLONOSCOPY
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
HALFLYTELY PREPARATION INSTRUCTIONS:
DAY BEFORE YOUR COLONOSCOPY
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.
a. Drink one 8 ounce serving of clear liquids EVERY HOUR from the time you rise until you
b. 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.
c. 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.
2. 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.
