A procedure similar to a colonoscopy using a long thin tube with a camera (scope) passed through the [[Human anus|anus]] but only intended to visualize the [[rectum]] and the [[Sigmoid colon|last part of the colon]] closest to the rectum. All aspects of the procedure are the same as for a colonoscopy with the exception that this procedure only lasts ten to twenty minutes and is done without sedation. This usually allows for the patient to return to normal activities immediately after the procedure is finished.<ref>{{Cite web |title=Flexible Sigmoidoscopy {{!}} NIDDK |url=https://www.niddk.nih.gov/health-information/diagnostic-tests/flexible-sigmoidoscopy |access-date=2022-12-09 |website=National Institute of Diabetes and Digestive and Kidney Diseases |language=en-US}}</ref>
