Flexible Sigmoidoscopy

What is a Sigmoidoscopy?

A sigmoidoscopy, often referred to as a flexible sigmoidoscopy, that is similar to a colonoscopy. The difference between the two is a colonoscopy is intended to examine your entire colon, while a sigmoidoscopy is only intended to examine your sigmoid colon. For the procedure, just like a

Flexible Sigmoidoscopy

colonoscopy, there will be a long and thin flexible tube that has a camera and light on the tip inserted through the rectum. The tube can blow little puffs of air to expand the colon to give the doctor a clearer view through the exam. Typically the patient isn't under sedation during this procedure. Though during the procedure you might feel uncomfortable, there is typically no pain involved in this procedure. If your doctor sees any abnormalities such as polyps or growths, they can either remove them or biopsy them. The procedure normally takes about 10 to 20 minutes to complete and patients will be receiving a sedative for the procedure, which will require them to have a ride drive them, stay with them and drive them home after the procedure.

Your doctor might suggest a sigmoidoscopy procedure to check for:

  • Ulcers
