Abstract

|
Colorectoanal intussusception is a rare and distinct entity that differs from the more common rectal prolapse. Typically the intussusception occurrs with tumor at the apex of the intussuscepted segment acting as lead point. Here we present a case and review the literature of colorectoanal intussusception. The case presented here is that of an elderly woman with a proximal sigmoid colon cancer at its apex. Anterior resection was electively performed after reduction of the intussusception. It is important to differentiate a colorectoanal intussusception from the more common rectal prolapse because treatment may differ. The anorectum remains in its normal anatomic position in colorectoanal intussusception, whereas the anal canal is effaced with the prolapsed segment of bowel in rectal prolapse. Identification of a tumor at the apex of the intussuscepted bowel should also arouse suspicion that the condition is not a rectal prolapse.
