Flexible Sigmoidoscopy

Flexible sigmoidoscopy is an examination of the inside lining of the pipe of the lower end of the large bowel (rectum and lower colon). It allows your specialist to investigate symptoms such as bleeding, pain, or changes in bowel habits.

What's Involved? The Examination Preparing for Surgery Find A Specialist

What is involved with a flexible sigmoidoscopy? 

During a flexible sigmoidoscopy a flexible digital camera (colonoscope) is passed in through the anus and moved around the rectum and colon. The picture from the digital camera is shown on a video screen so that your specialist can see the lining of your bowel.  

If necessary, polyps can be removed through the scope. Tissue samples (biopsies) can also be taken during the procedure.  

Flexible sigmoidoscopy can be useful to: 

  • Investigate symptoms such as bleeding from the bowel 

  • Look for polyp regrowth for people who have had them removed before 

  • Following colon surgery to check joins made in the bowel  

  • During treatment for rectal cancer 

The Examination

The examination is an outpatient procedure. It usually lasts 10 to 20 minutes.

Our team of specialists and nurses are experts at conducting flexible sigmoidoscopy. They will answer any questions that you have about having a flexible sigmoidoscopy and will make sure that you are safe and comfortable throughout your procedure.  

Step 1

When you arrive for your flexible sigmoidoscopy you’ll be asked to change into a hospital gown. You’ll be brought into the endoscopy suite.

Step 2

Your specialist will offer you some sedation. Sedation helps to make sure you are comfortable throughout the procedure. You may choose to have your flexible sigmoidoscopy without any sedation. Please discuss this with your specialist.

Step 3

 You lie on your left side or back for the examination. You may be asked to turn onto your stomach or right side. This can help to scope to move through the bowel more easily. This procedure usually lasts 10 to 20 minutes.
