Polypectomy is a procedure to remove polyps (precancerous growths that develop in the lining of the colon) before they can become cancerous, and to relieve symptoms of bowel irregularities, abdominal pain and rectal bleeding. Polypectomy is usually performed as an outpatient, endoscopic procedure by inserting a scope with a camera through the anus to reach the site of the polyp. The polyps are removed with a wire loop or electric current through the scope.
