An advanced polypectomy is a method used to remove large pedunculated polyps in the bowel. Pedunculated means the polyp is on a stalk.

The lining of the bowel is made of cells that are constantly being renewed. Sometimes these cells grow too quickly, forming a clump of cells known as a bowel polyp (sometimes known as an adenoma). Polyps are not bowel cancers (they are usually benign), but they can change into a malignant cancer over a number of years.

A long flexible tube called a colonoscope is passed along the bowel to find the polyp seen during your previous test. Carbon dioxide or air is gently pumped in to the bowel to allow good views of the polyp during its removal. If the stalk is greater then 1cm it is injected with adrenaline. This reduces the risk of immediate bleeding and can stiffen the stalk, making the polyp less mobile and easier to remove

A wire loop is then passed down the colonoscope and over the polyp, which then can be removed. Diathermy (a low electrical current) is used to remove the polyp and seal the area left behind. The polyp is collected and sent for examination under the microscope.
