Polyps are relatively common in children. Many of these are juvenile polyps which are not cancerous. Some polyps occur as part of a polyposis syndrome. As part of both the evaluation and treatment of polyps, they are removed endoscopically by polypectomy. This is done through the colonoscope if the polyps are in the colon (large intestine) which is the most common location, or through the endoscope if the polyps are in the stomach or small intestine. If the polyp is very small, it may be removed with a biopsy forcep which is passed through the endoscope or colonoscope. If the polyp is larger, the base of the polyp is grabbed by a snare which is passed through the endoscope or colonoscope. This allows the polyp to be taken off. Whether removed by biopsy forceps or snare, the polyp is sent to pathology to be examined under a microscope to determine what type of polyp it is.
