A flexible sigmoidoscopy is an exam used to evaluate the rectum and lower part of the colon. During a flexible sigmoidoscopy exam, a thin, flexible tube is inserted into the rectum. If necessary, tissue samples (biopsies) can be taken through the scope during the procedure. This procedure does not allow the physician to see the entire colon; only the last one to two feet are examined.
A Flexible sigmoidoscopy is performed to help diagnose certain symptoms such as: bleeding, diarrhea, pain, and more.
When having this procedure, your physician will ask you to buy over the counter products/medications to help clear your colon out for visualization. You may also be asked to do a clear liquid diet the day before and stop certain routine medications. A detailed list of instructions will be given at the time of your consultation.
