How is it Done?
A small catheter for intravenous (IV) medicine is inserted into your arm. The medication will help you relax and become sleepy. You’ll be placed in a comfortable position on your left side. Your physician will gently examine your rectum with a lubricated, gloved finger. A large flexible tube called a colonoscope, will be inserted into your rectum and moved throughout the length of the colon to view the lining of the large intestine. You may be placed in a different position during the exam, such as on your back, to make it easier to pass the instrument through the entire large bowel. If a suspicious area is noted, a small tissue sample will be taken and tested to make a diagnosis. The examination takes approximately 30 minutes.
