Flexible Sigmoidoscopy

Flexible Sigmoidoscopy Description

Flexible sigmoidoscopy lets your gastroenterologist examine the lining of the rectum and a portion of the colon (large intestine) by inserting a flexible tube about the thickness of your finger into the anus and slowly advancing it into the rectum and lower part of the colon.

Flexible Sigmoidoscopy Preparation

Your gastroenterologist will tell you what cleansing routine to use. In general, preparation consists of one or two enemas prior to the procedure but could include laxatives or dietary modifications as well.

Most medications can be continued as usual. Inform your gastroenterologist about medications that you're taking - particularly aspirin products or anticoagulants (blood thinners) -- as well as any allergies you have to medications.

What can I expect during flexible sigmoidoscopy?

Flexible sigmoidoscopy is usually well tolerated. You might experience a feeling of pressure, bloating or cramping during the procedure. You will lie on your side while your gastroenterologist advances the sigmoidoscope through the rectum and colon. As your gastroenterologist withdraws the instrument, your gastroenterologist will carefully examine the lining of the intestine.

If your gastroenterologist sees an area that needs further evaluation, they might take a biopsy (sample of the colon lining) to be analyzed. Biopsies are used to identify many conditions, and your gastroenterologist might order one even if he or she doesn't suspect cancer.

If your gastroenterologist finds polyps, they may take a biopsy of them as well. Polyps, which are growths from the lining of the colon, vary in size and types. Polyps known as "hyperplastic" might not require removal, but benign polyps known as "adenomas" are potentially precancerous. Your gastroenterologist might ask you to have a colonoscopy (a complete examination of the colon) to remove any large polyps or any small adenomas.

After the Procedure

You might feel bloating or some mild cramping because of the air that was passed into the colon during the examination. This will disappear quickly when you pass gas. You should be able to eat and resume your normal activities after leaving your gastroenterologist's office or the hospital, assuming you did not receive any sedative medication.
