title: Treatment of internal rectal intussusception in patients with chronic constipation.
abstract: BACKGROUND
  The significance of internal rectal intussusception (rectal invagination) in chronic constipation dominated by symptoms of obstructed defecation is not fully clarified.
  
  
  METHODS
  Seventeen consecutive patients with chronic constipation and a history of obstructed defecation with internal rectal intussusception demonstrated by defecography were treated by perineal rectopexy.
  
  
  RESULTS
  Of 15 patients followed up for more than 2 years defecography showed total disappearance of the intussusception in 12. Five of these claimed substantial improvement (42%; 17-72%). Three of four patients with concomitant anal incontinence became fully or partly continent after the rectopexy.
  
  
  CONCLUSIONS
  In some patients with chronic constipation, dominated by symptoms of obstructed defecation, rectal invagination may be an aggravating factor. The study indicates that rectal invagination does not seem to be the cause but rather a consequence of the obstructed defecation. In selected patients, including those with concomitant faecal incontinence, surgical treatment of the intussusception by a minor procedure may be indicated.
