摘要

The anorectum corresponds to the last segment of the gastrointestinal tract and is responsible for mediating fecal continence and controlled defecation. An understanding of the complex topographic anatomy is an indispensable prerequisite for the surgical treatment of benign and malignant diseases in the anorectal region. The detailed description of perirectal fascia, anorectal blood supply and lymph vessel drainage, pelvic autonomic nerves and components of the anal canal and anal sphincter complex has significantly contributed to improvement of the oncological and functional surgical outcome. In this article the state of knowledge relating to the anorectal anatomy is outlined providing a practical basis for rectal and proctological surgical procedures.
