Anterior rectocoele and recto-anal intussusception

Case contributed by Dr Matthew Lukies


Feeling of incomplete defecation. Suspected partial thickness rectal intussusception.

Patient Data

Age: 60 years
Gender: Female

Preliminary images are unremarkable.

The fluoroscopic images taken upon bearing up and bearing down demonstrate marked elevation and descent of the ano-rectal junction on bearing up and down, respectively.

The fluoroscopic images taken upon defecation demonstrate:

  • moderate to large degree of protrusion of the anterior rectal wall (anterior rectocoele) that incompletely empties during defecation but is not obstructive
  • recto-anal intussusception (internal prolapse) with the rectum protruding to the anal verge
  • rectal descent to the anal canal, but no external prolapse

There is a small amount of contrast remaining in the rectum post evacuation.
