The risk of internal rectal intussusception progressing to rectal prolapse is low. Surgery is generally not indicated for rectal intussusception based on this risk alone.

Area of Science:

  • Gastroenterology
  • Colorectal Surgery
  • Diagnostic Imaging

Background:

  • Internal rectal intussusception is a condition where the rectal lining telescopes inward.
  • Rectal prolapse involves the outward protrusion of the rectal wall.
  • Understanding the progression from intussusception to prolapse is crucial for treatment decisions.

Purpose of the Study:

  • To determine the incidence of internal rectal intussusception progressing to complete rectal prolapse.
  • To evaluate the natural history of internal rectal intussusception in patients with persistent symptoms.

Main Methods:

  • A cohort of 312 patients with persistent symptoms underwent repeated defecography.
  • The study focused on 79 patients diagnosed with rectal intussusception on initial defecography.

  • Subsequent defecography results and patient records were analyzed for progression to rectal prolapse.

    • Main Results:

    • Out of 38 patients who did not receive surgical treatment between investigations, one developed rectal prolapse.
    • Another patient experienced a clinical prolapse after the second defecography.
    • The progression rate from internal rectal intussusception to overt rectal prolapse was found to be low.

    Conclusions:

    • The likelihood of developing rectal prolapse from internal rectal intussusception is minimal.
    • The risk of progression is not a sufficient criterion to warrant surgical intervention for rectal intussusception.
