What does LAR stand for in colorectal surgery?

Explanation:
Low anterior resection describes a tumor-removal procedure that preserves the anal sphincter, removing the diseased portion of the rectum and rejoining the remaining colon to the remaining rectal or anal canal to maintain bowel continuity. The term “low” indicates that the resection is near the anal canal, as opposed to higher up in the rectum, which is why this approach can spare the sphincter and avoid a permanent colostomy like in abdominoperineal resection. The other phrasings aren’t standard terms for this operation, so they don’t accurately describe the targeted, sphincter-sparing rectal procedure.
