| [ Summary ] |
Treatment for early rectal cancer requires not only a cure but also preservation of sphincters, as well as urinary, and sexual functions. The Herrmann's line, dentate line, and intersphincteric groove are important landmarks in the anal canal to determinine the level at which the sphincter muscle ought to be cut. The visceral pelvic fascia contains pelvic organs and accompanying nerves and vessels, and is attached to the tendinous arch of the sphincter muscle at the bottom of the pelvic floor. |
