Internal rectal prolapse (intussusception) is the result of chronic strain for defecation, due to chronic constipation or pelvic floor dysfunction, which develops lengthening of the attachments of rectum to sacrum leading to descending perineum syndrome. (2,20) Intussusception is the result of increased mobility of the rectum and causes outlet obstruction, since the upper rectum moves away from the sacrum and pushes into the more distal rectum.
The phenomenon has been variably referred to in the literature as enterocele, descending perineum syndrome, peritoneocele, or Pouch of Douglas hernia.
