Why Do I Need It?
A colonoscopy is usually
done to help your doctor evaluate and treat your lower GI symptoms, such
as lower abdominal pain, diarrhea, constipation, rectal bleeding or anemia.
It is also performed on healthy people with no symptoms as a screening tool
for colon cancer. Colonoscopy is more accurate than x-rays for detecting
bleeding in the lower GI tract, polyps and tumors. Some conditions
can be treated during the procedure by passing small instruments through
the endoscope. For example: biopsies can be taken, polyps removed
and treatment of lower GI bleeding can be given. These treatments usually
painless.
What are Polyps?
Polyps are abnormal growths
on the lining of the colon. The large majority of polyps are not cancerous
but some types of polyps have the potential to turn into cancer with time.
Polyps can also bleed. For these reasons, most polyps are removed during
colonoscopy and sent to the laboratory for a microscopic examination.
What Are the Risks?
While any medical procedure
has risks, a colonoscopy is generally safe when performed by a physician
who is specially trained and experienced in them. Possible complications
include perforation of the bowel wall, bleeding and drug reactions.
Will it Hurt?
While it is normal to
have some degree of apprehension prior to your test, you should experience
little discomfort. You will be given intravenous sedation or a light
anesthetic before the procedure to help you relax. One or more of
the following medications may be used: Propofol, Versed, Demerol and
Fentanyl. If you are allergic to any of these medications, please
notify the office before your procedure.
What Preparation
is Needed?
The colon must be completely
clean for the procedure to be performed. You may be given one of several
different preps to cleanse your bowel:
Co-Lyte
, Golytely
, Nulytely
, HalfLytely
or Miralax
. You will also need to be on a clear liquid
diet for a time before your procedure.
Should I Take
my Medications the Morning of my Procedure?
You may take any essential
medicines, such as heart, asthma, blood pressure and anti-seizure medications.
Please Call the office five days before your procedure for instructions
on any blood thinners (aspirin, plavix, coumadin)
