Rupture of sigmoid colon with evisceration of bowel loops through the anus

Spontaneous  rupture  of  sigmoid  colon  with  small  bowel  evisceration  through  anus  is  rare  and  an  acute  gastrointestinal  emergency. It occurs in patients with rectal prolapse. Protrusion of loops of small bowel through the anal orifice is usually associated with spontaneous rupture of the distal sigmoid colon or rectum caused by a sudden increase of intra-abdominal pressure.
