Carle Richland Memorial Hospital performs Flexible Sigmoidoscopy procedures in its GI Lab. It is an examination used to see inside the sigmoid colon and rectum. Flexible Sigmoidoscopy can detect inflamed tissue, abnormal growths, and ulcers. The 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. Flexible Sigmoidoscopy differs from colonoscopy in that it enables the doctor to see only the sigmoid colon, whereas colonoscopy allows the doctor to see the entire colon. Depending on the specific problems you are having, your doctor may choose to perform a Flexible Sigmoidoscopy rather than a full colonoscopy. Consult your doctor about any gastrointestinal problems you may be experiencing.
