Flexible Sigmoidoscopy (Flex Sig)
A flexible sigmoidoscopy is a procedure used to see inside the sigmoid colon and rectum. It can detect inflamed tissue, abnormal growths and ulcers. This procedure is used to look for early signs of cancer and can help doctors diagnose unexplained changes in bowel habits, abdominal pain, bleeding from the anus and weight loss. During a flexible sigmoidoscopy the doctor can take samples from abnormal looking tissue and send it for a biopsy.
A colonoscopy is the preferred screening method for cancers of the colon and rectum because it allows the doctor to see the entire colon where the flexible sigmoidoscopy only allows the doctor to see a small portion of the colon. However, for various reasons your doctor may suggest this procedure instead of a colonoscopy. You will need to discuss these reasons with your doctor.
