Rectum: prolapse

Contributor(s): James Simpson

Introduction

  • Eversion of one or more layers of rectum through the anus.
  • Causes: persistent straining due to urogenital or alimentary disease, most commonly severe colitis/proctitis associated with endoparasites.
  • Signs: tenesmus, rectal mass.
  • Diagnosis: differentiate from ileocolic or colic intussusception.
  • Treatment: eliminate underlying cause while alleviating immediate discomfort caused by the rectal prolapse. Colopexy may be required.
  • Amputation of the prolapsed rectum is the preferred treatment if, on initial presentation, the rectal mucosa is necrotic, lacerated or irreducible.
  • Prognosis: guarded due to complications such as strictures, incontinence or leakage from the anastomotic site following amputation.
