local transanal resection
[lo-kul tranz-a-nuhl re-sek-shun]
surgery for some small, early rectal cancers that is done with instruments put in through the anus, without cutting the abdomen (belly). The surgeon cuts through all layers of the rectum to remove invasive cancers as well as some normal rectal tissue, and then closes the hole in the rectal wall. Compare to low anterior resection. See also anus, invasive cancer, rectum.
