A flexible sigmoidoscopy (sig-moi-DOS-kuh-pee) is an exam used to evaluate the lower part of the large intestine (colon). During a flexible sigmoidoscopy exam, a thin, flexible tube (sigmoidoscope) is inserted into the rectum.
A tiny video camera at the tip of the tube allows the doctor to view the inside of the rectum, the sigmoid colon and most of the descending colon — just under the last 2 feet (about 50 centimeters) of the large intestine. If necessary, tissue samples (biopsies) can be taken through the scope during a flexible sigmoidoscopy exam.
Flexible sigmoidoscopy doesn't allow the doctor to see the entire colon. As a result, flexible sigmoidoscopy alone can't detect cancer or small clumps of cells that could develop into cancer (polyps) farther into the colon.
A flexible sigmoidoscopy exam poses few risks. Rarely, complications of a flexible sigmoidoscopy exam may include:
Any residue in your colon may obscure the view of your colon and rectum during the exam.
To empty your colon, follow your doctor's instructions carefully. You may be asked to:
Wearing a gown, you'll begin the exam lying on your left side on the exam table, usually with your knees drawn toward your abdomen. The doctor will insert a sigmoidoscope into your rectum.
The sigmoidoscope contains a light and a tube that allows the doctor to place air into your colon. The air expands the colon, which provides a better view of the colon lining. When the scope is moved or air is introduced, you may feel abdominal cramping or the urge to move your bowels.
The sigmoidoscope also contains a tiny video camera at its tip. The camera sends images to an external monitor so that the doctor can study the inside of your colon. The doctor can also insert instruments through the scope to take tissue samples.
A flexible sigmoidoscopy exam typically takes about 15 minutes. It may require slightly more time if biopsies are taken. Sedation and pain medications usually aren't necessary. If a polyp is found, your doctor will likely recommend a full colonoscopy to look at your whole colon, as other polyps may be present further up in the colon.
You may feel bloated or pass gas for a few hours as you clear the air from your colon. Walking may help relieve any discomfort. You should be able to return to your usual diet and activities right away.
You may also notice a small amount of blood with your first bowel movement after the exam, which usually isn't cause for alarm. Consult your doctor if you continue to pass blood or blood clots or if you have persistent abdominal pain or a fever of 100 F (37.8 C) or higher.
The results of a flexible sigmoidoscopy exam are considered negative if the doctor doesn't find any abnormalities in the colon. If you're at average risk of colon cancer — you have no colon cancer risk factors other than age — your doctor may recommend waiting five years before repeating the exam.
The results of a flexible sigmoidoscopy exam are considered positive if the doctor finds polyps or abnormal tissue in the colon. Depending on the findings, you may need additional testing — such as a colonoscopy — so that any abnormalities can be examined more thoroughly, biopsied or removed. During colonoscopy, your doctor can also screen the entire colon for other abnormalities.
