Sigmoidoscopies are procedures which allow doctors to inspect the inside surface of the rectum and lower large bowel (Sigmoid Colon). As opposed to colonoscopies, sigmoidoscopies only involve the examination of the lower part of the colon, while colonoscopy allows doctors to view both the upper and lower sections. Sigmoidoscopies are typically performed under a sedation anaesthetic and involve the insertion of an endoscope, a thin, flexible tube with its own inbuilt video camera, lens and light source, into the anus.
Sigmoidoscopies are performed to examine the rectum and Sigmoid Colon for various conditions including inflammation, abnormal blood vessels and flat polyps (benign wart like growths). Various therapeutic procedures may be performed during the sigmoidoscopy; these include the biopsy of tissue to investigate possible malignancy and the removal of polyps. As colon cancer arises from pre-existing polyps, any polyps that are found are removed at the time of examination. Most polyps can be burnt off by placing a wire snare around the base and applying an electric current.
For legal reasons you must not drive a vehicle or operate machinery until the day after your procedure, but preferably not for 24 hours following your sedation anaesthetic. Driving under the influence of sedation carries the same implications as with alcohol. You must have a responsible adult to collect you from day surgery, drive you home and care for you for at least 12 hours post procedure.
