Colocolic Intussusception without Lead Point; A Case Report and Literature Review

Background: Colocolic intussusception is rare in children and most cases in adolescents are produced by a lead-point. A review of the English-written literature revealed only three cases of colocolic intussusception without lead point.
Case presentation: A seven year-old boy with chief complaint of colicky abdominal pain and vomiting for five days, dysentery for 4 days, and no response to antibiotic therapy, increasing pain and abdominal distension was referred to pediatric gastroenterologist. Abdominal x-ray revealed multiple air-fluid levels and gasless colon. Pseudo-kidney appearance was reported in abdominal ultrasound at splenic flexure. Colocolic intussusception diagnosis without any lead point was confirmed in laparotomy and reduced with milk-out procedure.
Conclusion: In children with dysentery especially in presence of colicky abdominal pain, abdominal distention and no response to antibiotic therapy, abdominal ultrasound to rule out intussusception is recommended.
