Background Intussusception is the most common cause of intestinal obstruction in young children, and delayed diagnosis may lead to serious sequelae. The objective of this study was to determine the prevalence of ileoileal intussusception and to document and compare clinical outcomes with ileocolic intussusception. Methods A retrospective cohort study of children with an abdominal ultrasound that diagnosed intussusception. Clinical data and diagnostic studies were retrieved, to compare ileoileal with ileocolic intussusception. Results A total of 488 patients were evaluated with an abdominal ultrasound on suspicion of intussusception; 54 (11%) had ileoileal intussusception and 30 (6%) ileocolic intussusception. The significant features distinguishing the 2 conditions were fever, more common in patients with ileoileal intussusception, and an abdominal mass, which was papable more commonly in ileocolic intussusception. None of the ileoileal intussusception patients required surgical intervention, and all were discharged without complication. Conclusions With recent advances in abdominal ultrasound, the diagnosis of ileoileal intussusception has become easier than before. Patients presenting with small bowel intussusception may not need any immediate intervention. The presence of fever supports the diagnosis of ileoileal intussusception.
