Pediatric intussusception often has a pathological lead point, commonly Meckel's diverticula. Age is key for diagnosis, while symptom duration is not, and enema reduction is safe.

Area of Science:

  • Pediatric Surgery
  • Gastroenterology

Background:

  • Intussusception is a common surgical emergency in children.
  • Identifying a pathological lead point is crucial for appropriate management.
  • Previous studies have explored factors associated with pathological lead points.

Purpose of the Study:

  • To identify the types and prevalence of pathological lead points in pediatric intussusception.
  • To determine factors that differentiate patients with pathological lead points from those with idiopathic intussusception.
  • To evaluate the success and safety of hydrostatic reduction in cases with a pathological lead point.

Main Methods:

  • Retrospective review of 56 pediatric patients with intussusception and a pathological lead point over 16 years.
  • Analysis of patient demographics, clinical presentation, lead point pathology, and treatment outcomes.

  • Comparison with patients diagnosed with idiopathic intussusception.

    • Main Results:

    • Meckel's diverticula were the most frequent pathological lead point, followed by polyps, lymphosarcomas, and duplication cysts.
    • Patient age at presentation was the only significant factor distinguishing pathological lead points from idiopathic intussusception.
    • Hydrostatic reduction was attempted in 21 cases with a pathological lead point, achieving success in 3 instances.
    • No morbidity or mortality was observed with a policy of initial enema reduction, irrespective of age.

    Conclusions:

    • Pathological lead points in pediatric intussusception are varied, with Meckel's diverticula being most common.
    • Age is a critical differentiator for pathological lead points, unlike symptom duration.
    • Initial enema reduction is a safe management strategy for intussusception, even with identified lead points.
