abdominoperineal resection

(ab-DAH-mih-noh-PAYR-ih-NEE-ul ree-SEK-shun)

The end of the intestine is attached to an opening in the surface of the abdomen and body waste is collected in a disposable bag outside of the body. This opening is called a colostomy. Lymph nodes that contain cancer may also be removed during this operation.
