A flexible sigmoidoscopy is a procedure that allows your doctor to examine the lower part of the large intestine, including the rectum and sigmoid colon. Using a thin, flexible tube with a light and camera, your gastroenterologist can check for abnormalities such as polyps, inflammation, bleeding, or signs of colorectal disease.
This test is often recommended for evaluating symptoms such as rectal bleeding, chronic diarrhea, abdominal pain, or changes in bowel habits. It may also be used as a screening tool for colorectal cancer or to monitor conditions like ulcerative colitis or diverticulosis. By focusing on the lower portion of the colon, a flexible sigmoidoscopy provides valuable information while being less invasive than a full colonoscopy.
You will be asked to follow preparation instructions, usually involving a special enema or mild bowel preparation to clear the lower colon. Sedation is not always required, but may be offered to help you relax. During the test, the doctor gently inserts the sigmoidoscope through the rectum and examines the lining of the sigmoid colon. If necessary, small tissue samples (biopsies) can be taken, and polyps can be removed. The procedure usually takes 15 to 30 minutes.
Most patients are able to resume normal activities soon after the test, especially if sedation is not used. Mild cramping, bloating, or a small amount of rectal bleeding can occur but typically resolves quickly. Your doctor will discuss any findings and advise whether further testing, such as a colonoscopy, is needed.
This procedure provides a safe and effective way to detect early signs of colorectal disease, identify causes of digestive symptoms, and remove polyps before they progress. It is quicker and often more convenient than a colonoscopy, while still offering valuable diagnostic insights.
Though rare, complications can occur. You should contact your doctor if you experience severe abdominal pain, heavy bleeding, fever, or dizziness after the test.
