Abstract
Rectal injury could be iatrogenic or noniatrogenic. The most common cause of rectal injury is iatrogenic. Perforation of the rectum can occur during barium enema, colonoscopy, polypectomy and some gynecologic and urologic procedures. The most common noniatrogenic cause of rectal trauma is gunshot wounds to the buttocks and perineum. Stab wounds from a knife or other sharp instrument and impalement may also result in rectal injury. (Janicke and Pundt 1996)
Rectal impalement involves foreign body trauma to the rectum resulting in intra- or extraperitoneal rectal injury. (Kim et al., 2006)
The history is obviously of paramount importance in assessing the presence and extent of rectal injury and valuable information may be gained from this history. (Fry 1994)
History of anal introduction of foreign bodies may be absent particularly if foreign bodies in the foods (such as fish bones, animal bones and crab shells) had passed down all the way from oral ingestion.
