The Most Common Types Of Colon Polyps And Polyp Disorders

Hyperplastic Polyps

Hyperplastic polyps are another common type and are typically benign. The usual treatment is a polypectomy or removal. A camera and electrified wire are inserted anally to remove small polyps, but larger ones must be removed using a similar process, except through the abdomen. Another removal process requiring an abdominal incision is called a laparotomy. Rarely, the colon and rectum are entirely removed if numerous polyps inhibit them, through a procedure called a total resection.

Carcinomatous Polyps

This type of adenoma is cancerous. Carcinomatous polyps are dangerous, though are also the rarest type, representing about five percent of adenomas found in screenings. Although typically surgically removed with a polypectomy, there is a risk of some of the cancer cells being left behind in the colon and spreading to other parts of the body. When this occurs, additional surgery is usually undertaken, especially when the lymph nodes or blood system are involved.
