How to Prepare for a Sigmoidoscopy?
- Your colon needs to be emptied by using enemas and/or laxatives before the sigmoidoscopy. The bowel needs to be empty of stool.
- You may also be required to be on a liquid diet since 1 or 2 days prior to the sigmoidoscopy.
- You will need to take an enema 1 hour prior to the procedure to clear the intestine thoroughly.
Examination of the Sigmoid Colon
During a flexible sigmoidoscopy, patients lie on their left side on an examination table. The doctor inserts a long, flexible, lighted tube called a sigmoidoscope, or scope, into the anus and slowly guides it through the rectum and into the sigmoid colon. The scope inflates the colon with air to give the doctor a better view. A small camera mounted on the scope transmits a video image from inside the colon to a computer screen, allowing the doctor to carefully examine the tissues lining the sigmoid colon and rectum. The doctor may ask the patient to move periodically so the scope can be adjusted for better viewing.
When the scope reaches the transverse colon, the scope is slowly withdrawn while the lining of the colon is carefully examined again.
What to expect after the Procedure?
After the procedure, you may experience mild abdominal cramping and gas as a result of the air that was placed in your intestine. Some people may have slight rectal bleeding due to minor irritation and trauma from the insertion of the sigmoidoscope.
