What is a polypectomy?
A polypectomy involves the removal of a polyp through a colonoscopy. Though they are rare, gastric polyps can also be removed through an endoscope.
How is it performed?
When a polyp is found through an endoscopic procedure, the endoscopist is able to insert biopsy forceps or other snare device through the endoscope to remove the polyp. Smalls polyps are usually able to be complete removed with forceps. Larger polyps are usually "snared off." after a polyp is snared, cautery may be used to burn the surrounding tissue to ensure complete removal of the polypoid tissue. Cautery or a heater probe may also be used to fulgurate (burn off) small, benign polyps.
What is a snare polypectomy?
A snare polypectomy is the removal of a polyp by looping a snare around the polyp and using heat to cut the polyp off and cauterize the area to prevent bleeding.
What are the risks of having a polypectomy?
There is a risk of bleeding and the chance that a hole may be made in the lining of the colon, which would then require additional surgical repair. The risk is very minimal, though, and the benefits of removing the polyp before it can advance into a cancerous tumor far outweigh any risk involved.
