What Is A Colonoscopy?

A colonoscopy is a very valuable procedure for the diagnosis and treatment of diseases of the colon. Colonoscopy allows the physician to examine the lining of the colon using a flexible tube. The decision to perform this procedure was based upon the assessment of your medical condition. If you are scheduled for a colonoscopy, it is your responsibility to check with your insurance carrier regarding coverage. Biopsies (tissue samples) may be taken and polyps (abnormal growths of tissue) may be found during the exam. These polyps may be cancerous or become cancerous in the future and should be removed. You will be notified of any pathology report in approximately two weeks.

IMPORTANT: BE SURE TO BRING A DRIVER (responsible adult, 18 years or older) as you will not be able to drive for 24 hours after the procedure. Have your driver plan to remain at the surgery center during your examination and recovery period. We will not perform a sedated procedure if you do not have a driver.

What Should I Expect During The Procedure?

You will be given medication through a vein in your arm to relax you and minimize discomfort. This is called moderate sedation. While you are lying on your left side, the colonoscope is advanced through the colon examining the lining of the colon. There may be some discomfort, but it is usually well tolerated and rarely causes significant pain. In rare cases, passage of the colonoscope through the entire colon cannot be achieved. Colonoscopy is safe and has very low risk when performed by a physician who is specifically trained and experienced in these procedures. A rare complication (1 in 1000) is a perforation in which a tear through the wall of the bowel may allow leakage of intestinal fluids into the abdominal cavity. This complication would require surgery to repair. At times, bleeding may occur from a biopsy or polyp removal. Other infrequent risks include infection, drug reactions and complications from unrelated diseases such as heart attack or stroke.

What Happens After The Colonoscopy?

Your doctor will want to talk to a relative or friend about your test following the examination. Please have your family/friend wait in the waiting room. You and your driver will receive a complete verbal explanation along with a copy of the homecare instruction sheet and other information the nurse determines would be helpful to your recovery. If you do not want your driver to receive information, tell your nurse during admission. Generally, you can leave 30 to 60 minutes after the procedure with your driver. You should not drive for 24 hours after the procedure.
