Colorectal Intussusception Due to Tubulovillous Adenoma in the Sigmoidorectal Junction: A Case Report

Adult intussusception is a rare disease with various clinical presentations and can cause grave surgical problems. The condition is associated with malignant and benign leading points in adults, unlike in children who mostly experience the latter. The colonic intussusception type can be more malignant than the enteric type, especially in distal parts of the colon. Sigmoidorectal intussusception is less common in adults; it usually presents as bowel obstruction or lower gastrointestinal bleeding. We reported a case of a middle-aged woman with sigmoidorectal intussusception who was treated by transrectal endoscopic surgery.
