The anorectum being in continuity with the colon and bearing similar contents is often treated like the colon. However, the rectum is muscular, thick walled, and more capacious. It is located deep inside the pelvic cavity and is well protected by the levator ani muscles, with the support of fat cushions all around particularly in both ischiorectal fossae. These features make anorectal injuries less common. They are very rare following blunt trauma as the muscular, capacious rectum does not give way easily. Because of rich blood supply from three sources and being the site of portosystemic anastomosis, rectal tears can be associated with considerable blood loss. There is a risk of incontinence following anorectal injury because of associated injuries to the complex continence mechanism surrounding it.
