Incidental finding of a sigmoid intussusception associated with rectal prolapse – A case report


Colonic intussusception in adults is extremely rare, accounting for about 5% of all cases of intussusception. The telescoping of a proximal segment in the lumen of the adjacent segment has a classic classical triad in the symptomatology of children: abdominal pain, bloody diarrhea and palpable abdominal mass. In the adult patient, the symptoms are almost absent, and rarely they consist of constipation, bloody stool, or a malignant pathology that accompanies intussusception, weight loss, and anemia. We present the case of a 86-year-old patient who underwent a surgical procedure for repairing a rectal prolapse; intraoperatively, we discovered a sigmoid intussusception for which we performed a segmentary sigmoidectomy, repairing the rectal prolapse by rectosacropexy with alloplastic mesh.

Key words: sigmoid intussusception, rectal prolapse, rectosacropexy.

Intussusception was first described in 1674 by Barbette of Amsterdam1 and further presented in a more detailed report in 1789 by John Hunter2, under the name of „intussusception“. Intussusception is defined as a rare form of bowel obstruction in adults (more common in children), which represents a telescoping of a proximal segment of the gastrointestinal tract called intussusceptum, into the lumen of the adjacent distal segment called intussuscipiens.
