Lower Endoscopy (Colonoscopy)
What is an Endoscope?
During endoscopy, a long, narrow, flexible tube called an endoscope is
used. This instrument contains a strong light and a microscopic video
camera. Your G.I. tract can then be viewed on a video screen.
A laxative is given prior to the exam to enable the visualization of the
colon. The endoscope is gently passed through the rectum and the entire
colon is visualized. During the procedure, photos may be taken along with
biopsies (samples) and polyps (growths) removed. These will help the physician
in determining a diagnosis.
A nurse will prepare the patient for the procedure by checking vital signs
and reviewing medical history/medications. An intravenous (I.V.) will
be established to administer a mild sedative for comfort throughout the
Following the procedure the patient will be closely monitored in our specially
equipped recovery room. Prior to the discharge, the nurse will review
post procedure instructions (a copy will be sent with the patient) and
answer any questions. Transportation arrangements must be made in advance,
as patients will not be able to drive themselves home.
