Glossary Term:


low anterior resection


low an-<b>teer</b>-ee-yer re-<b>sek</b>-shun


a surgical approach used for cancers in the upper two-thirds of the rectum, close to where it connects to the colon. The incision (cut) is made through the abdomen (belly) only, and the cancer is removed along with a margin (edge) of normal tissue, lymph nodes, and fatty and fibrous tissue around the rectum. The colon is re-attached to the part of the rectum that is left so that a colostomy is not needed. See also colo-anal anastomosis, colon, colostomy, lymph node, rectum.
