title: Adult rectosigmoid junction intussusception presenting with rectal prolapse.
abstract: Most cases of intussusception in adults present with chronic and nonspecific symptoms, and can sometimes be challenging to diagnose. We herein report on a patient with the rare symptom of colonic intussusceptions presenting with rectal prolapse and review the existing literature of similar case reports to discuss how to reach an accurate diagnosis. A 75-year-old woman with dementia presented with per rectal bleeding, rectal prolapse and lower abdominal pain. An operation was scheduled and a large sigmoid intussusception with a polyp as a leading point was found intraoperatively. She subsequently recovered well and was discharged. As large sigmoid intussusceptions may present as rectal prolapse, intussusception should be considered as a differential diagnosis for immobile patients, especially when the leading point is a lesion.
