A polypectomy is a procedure used to remove polyps from the inside of the colon, also called the large intestine. A polyp is an abnormal growth of tissue that is usually benign. The procedure is relatively non-invasive and is usually carried out at the same time as a colonoscopy.

Why have a polypectomy?

Many tumours of the colon develop as a benign (non-cancerous) growth before becoming malignant (cancerous).

A colonoscopy is first done to detect the presence of any polyps. A colonoscopy involves a flexible telescopic camera which is passed through the anus to look at the lining of your large bowel.

If polyps are detected, a polypectomy is performed and the tissue is removed. The tissue will be examined to determine if the growths are cancerous, precancerous, or benign. This can help prevent colon cancer.

Polyps aren’t often associated with any symptoms at all. However, larger polyps may cause:

• Rectal bleeding
• Abdominal pain
• Bowel irregularities
