Intussusception of the Appendix Induced by Sessile Serrated Adenoma: A Case Report

Intussusception of the appendix vermiformis is a rare condition. It occursmainly in infants and children. Here, we report an intussusception case thatoccurred in a 65-year-old male presenting with repeated periumbilical pain,nausea, vomiting and febrile sensation. The appendix was seen to beintussuscepted at laparoscopy. The invaginated segment was reducted and simpleappendicectomy was carried out. Histopathologic examination revealed a sessileserrated adenoma at the wall of the appendix, suggesting it as the cause of theintussusception.
