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.^[1]

Relation to abdominoperineal resection

LARs, generally, give a better quality of life than abdominoperineal resections (APRs).^[2]^[3] Thus, LARs are generally the preferred treatment for rectal cancer insofar as this is surgically feasible. APRs lead to a permanent colostomy and do not spare the sphincters.

BACKGROUND: Septal deviations represent a major cause of aesthetic disorders and respiratory obstruction. The traditional septoplasty techniques may often be inadequate to treat severe deviations. Recently, we described a modified extracorporeal septoplasty approach based on partial resection of the

Leaflet resection with sliding valvuloplasty or additional chordal replacement is a standard technique for very large posterior leaflet prolapse. Regular chordal replacement without resection is simpler than those techniques. However, it may not reduce the leaflet height enough to avoid systolic ant
