This case series presents two patients with symptoms consistent with acute rectal prolapse. The prolapses were subsequently found to be sigmoid intussusception that had prolapsed through the anus without rectal prolapse and without any intraluminal pathology or lead point. Both were recognised on examination and underwent colonic resection rather than proctectomy.
