Lower gastroenterology endoscopy is a direct examination of your large
bowel. A colonoscope is a soft, flexible instrument, about the diameter
of a finger, with a light and lens at the end which allows your doctor
to see into your colon. Flexible sigmoidoscopy is an examination
of only a short portion of the lower colon. the tube-like instrument
is inserted into the rectum and advanced through the colon so that visual
inspection can be carried out. During, the procedure you will be
laying on your left side. Your doctor can then take samples from
the colon lining, including biopsies and brushings, if needed. This
sampling is not painful. Certain treatments may also be given thorough
the scope as in the removal of polyps.
You may have a sensation of bloating, gas or cramping as air is pumped
into the colon for better visualization.
1. Drink one bottle of Magnesium Citrate the night before
2. Take two Fleet enemas about 2-3 hours before your procedure.
3. Do NOT eat or drink after midnight before the procedure.
Your usual medications can usually be taken with a sip of water, but please
discuss this beforehand with your doctor. Your stomach should be
empty during the test.
4. Arrive at the hospital one-half to one hour prior to your
scheduled procedure time. Bring your insurance cards and information.
5. This test may be done with no sedation, in which case you
may leave immediately after the test is over and drive yourself home.
If you plan on receiving sedation for this test, a responsible person must
come with you who can stay during the procedure and drive you home.
What To Expect:
Before your procedure you will be interviewed by a Registered Nurse.
She will ask some questions about your symptoms, health history and take
your blood pressure, pulse and temperature. If you do not know them
by name, please bring a list of your allergies and current medications.
The nurse will also insert a small needle into a vein in your arm if your
are receiving sedation. If you do not receive sedation for this test
you may go home as soon as your procedure is completed. If you received
sedation, after your procedure you will be sleepy. You can expect
to feel bloated or crampy and pass gas from your rectum. This is
just air that was pumped in through the scope during your procedure and
you should not be embarrassed to pass it. Your blood pressure and
pulse will be monitored frequently. You will stay in the recovery
area until you are alert and oriented and your vital signs are stable,
usually about one hour after your sedation was given. You may
be drowsy for a few hours after you go home. Your doctor will talk
to you or the person who came with you before you go home. If biopsies
were taken, it will take 3-4 days to get the report. You will receive
written discharge instructions and appropriate teaching materials before
you leave. If you received sedation, you will not be able to drive for
the rest of the day and should not plan on working the day of your test.
