Flexible sigmoidoscopy is a procedure used to examine the lower part of the colon (sigmoid colon) and rectum. It involves inserting a flexible, thin tube with a camera (sigmoidoscope) through the rectum to inspect the colon's lining for abnormalities.
Flexible sigmoidoscopy is primarily used for screening and diagnosing conditions such as colorectal cancer, polyps, and inflammatory bowel disease (IBD) in the lower part of the colon.
Flexible sigmoidoscopy may occasionally be preferred over colonoscopy because the preparation for sigmoidoscopy and the test itself may take less time. In addition, an anesthetic is often not required. There is a lower risk of direct harm such as a tear in the colon or rectum wall (perforation) with sigmoidoscopy, compared with colonoscopy. You should have this procedure at least once every 5 years if doing a flexible sigmoidoscopy for colon cancer screening purposes.
During a flexible sigmoidoscopy, you will typically lie on your side while Doctor Patel gently inserts the sigmoidoscope through the rectum. Doctor Patel will carefully examine the colon's lining for any abnormalities and may take tissue samples (biopsies) if necessary.
Before a flexible sigmoidoscopy, you may need to follow dietary restrictions and use enemas or laxatives to cleanse the lower colon. Your doctor will provide specific instructions to ensure a successful procedure.
To empty your colon, follow your Doctor Patel’s instructions carefully. You may be asked to:
After the flexible sigmoidoscopy, you may experience minor discomfort, such as bloating or cramping. You can usually resume your normal activities and diet immediately. Doctor Patel will discuss the findings and any necessary follow-up care. You may also notice a small amount of blood with your first bowel movement after the exam, which usually isn't cause for alarm. If bleeding, abdominal pain, or fever persist, contact our office immediately at 949-298-7112 and go to your nearest emergency room.
