A lower anterior resection, formally known as anterior resection of the rectum and anterior excision of the rectum or simply anterior resection (less precise), is a common surgery for rectal cancer and occasionally is performed to remove a diseased or ruptured portion of the intestine in cases of diverticulitis. It is commonly abbreviated as LAR.
LARs are for cancer in the proximal (upper) two-thirds of the rectum which lends itself well to resection while leaving the rectal sphincter intact.

Famous quotes containing the word anterior:
“But now moments surround us
Like a crowd, some inquisitive faces, some hostile ones,
Some enigmatic or turned away to an anterior form of time
Given once and for all. The jetstream inscribes a final flourish
That melts as it stays.”
—John Ashbery (b. 1927)
