Anorectal injuries are not uncommon, and can have a variety of causes. The most common cause of anorectal injury is trauma, which can include straining during a bowel movement or childbirth, vehicle accidents, falls, assaults, and physical abuse. Other causes of anorectal injury include foreign objects, radiation therapy, and surgery.
Trauma
Trauma is the most common cause of anorectal injury. Straining during a bowel movement or childbirth can lead to anorectal trauma, as can vehicle accidents, falls, assaults, and physical abuse.
Foreign Objects
Foreign objects, such as a misplaced enema tip or a forgotten toy, can also cause anorectal injuries. Accidental insertion of objects into the rectum is also possible, especially in children and adults with developmental disabilities.
Radiation Therapy
Radiation therapy can cause damage to the rectal tissue, leading to anorectal injury. Radiation therapy can be used to treat a variety of cancers, including those of the rectum and anus.
Surgery
Surgery can lead to anorectal injuries, especially if the surgeon is inexperienced or careless. Surgical procedures such as hemorrhoidectomies and colostomies can cause damage to the rectal tissue if not performed correctly.
