Flexible sigmoidoscopy examines the lower part of the large bowel using a thin, flexible camera, offering a shorter procedure and simpler preparation than a full colonoscopy when symptoms suggest a lower-bowel cause. Mr Kimble performs this at Mount Stuart Hospital, Torquay.
What is a flexible sigmoidoscopy?
It’s an examination of the rectum and the lower part of the colon (the sigmoid colon), using a flexible camera passed through the anus. It allows direct visualisation of the bowel lining in this region, with biopsies or polyp removal possible during the same visit if needed.
When it is used instead of a full colonoscopy
- Symptoms strongly suggest a lower-bowel cause, such as localised rectal bleeding
- A shorter preparation and procedure time is preferred
- Follow-up examination after previous lower-bowel findings
- As an initial step before deciding if a full colonoscopy is needed
Mr Kimble will advise which examination, flexible sigmoidoscopy or full colonoscopy, is right for your specific symptoms.
Your treatment options
How the procedure is delivered can be adapted slightly depending on your symptoms and comfort preferences.
Usually just a single enema shortly before the appointment, simpler than full colonoscopy preparation.
Most patients tolerate flexible sigmoidoscopy well without sedation, allowing you to drive yourself home after.
If anything is found, a small sample or the polyp itself can usually be removed during the same procedure.
If findings suggest a cause higher up the bowel, full colonoscopy can be arranged promptly as the next step.
Recovery & aftercare
Most patients go home the same day, often without needing sedation. You’ll be given clear guidance on what to expect and when to expect any biopsy results.
Bleeding has several possible causes, and a proper assessment is the only way to be sure. Booking an appointment is the fastest way to get a clear answer.
