Only 5% of all cases of intussusceptions occur in adults. Intussusception complicating colonoscopy is an extremely rare event. Herein, we present a case of a 58-year-old man who developed ileocolic intussusception after a colonoscopy during which an adenomatous polyp was discovered in the terminal ileum. Eight hours after colonoscopy, the patient developed diffuse abdominal pain associated with vomiting and bloody diarrhea. A contrast-enhanced abdominal computed tomography scan revealed features of mechanical intestinal obstruction and a round soft tissue mass inside the right colon, followed by the wall of the intussusceptum. Emergency laparotomy revealed extended ileocecal intussusception with the polyp incarcerated by the ileocecal valve. A typical right hemicolectomy was performed, and the patient had an uneventful recovery. Histologic examination of the surgical specimen revealed an inflammatory fibroid polyp. Ileocolic intussusception due to an ileal polyp may be precipitated by colonoscopy and should be included in the differential diagnosis of acute abdomen after colonoscopy.

Background: Ileocolic intussusception is the most common form of intussusception in children. Intussusception in the appendix or cecum without a lead point in a child is very rare and was found with total colonoscopy (TCS) and computed tomography. Case Presentation: A 9 year-old boy was admitted to our hospital with fever, vomiting, and two episodes of bloody diarrhea. Inflammatory bowel disease was suspected; TCS was performed and revealed intussusception whose advanced region was in the cecum. The diagnosis was idiopathic cecum intussusception. This case was unusual in that intussusception had occurred at a young age but without lead point; in addition, the intussusception had also occurred at the tip of the cecum. The intussusception was safely reduced by endoscopic procedures, and after improvement in the vomiting, the patient was safely discharged and has had no bloody stools since. Conclusion: We demonstrated cecal intussusception without lead point observed on TCS in a child.
