Polypectomy
A polyp is a small growth on the bowel lining. Most are harmless, but most bowel cancers begin as one. Removing a polyp during colonoscopy takes minutes, is painless, and is one of the few things in medicine that genuinely prevents a cancer rather than catching it early.
- Removed during the same colonoscopy
- Painless, done under sedation
- Sent for testing afterwards
- Genuine prevention, not early detection
Stay
Day care
Duration
Adds 5 to 20 minutes to the colonoscopy
Anaesthesia
Sedation, as for the colonoscopy
About Polypectomy
Polyps are removed with a wire snare passed through the colonoscope, or with forceps if they are very small. The tissue is sent for examination, which determines whether it was the type that could have become cancerous and when a repeat colonoscopy should be arranged. Because the bowel lining has no pain sensation of the sort skin has, the removal itself is not felt.
- Removed with a snare or forceps through the scope
- Every polyp is sent for testing
- The result determines when to repeat the colonoscopy
- Not felt during or afterwards in most cases

Before you read on
Everything here is general information about polypectomy. Whether it suits you, and how it would be done in your case, is a decision for your doctor after examining you.
Your consultant's instructions always take precedence over anything written on this page.
When is it recommended?
Situations in which a doctor may suggest polypectomy.
- Polyps found during a colonoscopy
- Follow-up colonoscopy in someone with previous polyps
- Bowel cancer screening where polyps are detected
- Family history of polyps or bowel cancer
Procedure details
The usual sequence, from first consultation through to follow-up.
Found during colonoscopy
The polyp is identified as the bowel is examined, and its size, shape and position are assessed.
Removal
A wire snare is passed around the base and the polyp removed, or forceps are used for very small ones. You will not feel it.
Securing the site
The base is checked and, where needed, clipped or treated to prevent bleeding before the scope is withdrawn.
Testing and follow-up
The polyp is sent to histopathology. The result decides the interval before your next colonoscopy.
How to prepare
What to sort out before you come in.
- The same bowel preparation as the colonoscopy
- Blood thinners are particularly important to declare, as they may need stopping in advance
- Tell the team about any bleeding disorder
- Arrange somebody to take you home

Recovery
What to expect afterwards, and roughly when.
- A small amount of blood in the stool for a day or two is common
- Avoid heavy lifting and strenuous exercise for a few days after a large polyp is removed
- Eat lightly for the first day
- Heavy bleeding, severe abdominal pain or fever needs immediate attention
- The histology result and the interval for your next colonoscopy follow in about a week
Why choose Humayun for polypectomy
The point of a colonoscopy is largely the polypectomy, so the equipment and the follow-up interval both matter.
- Polyps removed at the same sitting rather than at a second appointment
- Clips and haemostasis equipment on the trolley, so bleeding is managed immediately
- Histopathology on site, which sets the correct interval for the next colonoscopy
- Follow-up intervals actually arranged rather than left to the patient to remember
