The leadpoint in intussusception
1Department of General Surgery, Royal Children's Hospital, Melbourne, Parkville, Australia.
Insights
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.
Abstract:
Fifty-six patients with a pathological lesion at the leadpoint of their intussusception were encountered at the Royal Children's Hospital, Melbourne, over a 16-year period. The most common lesions were Meckel's diverticula, followed by small bowel polyps, lymphosarcomas, and duplication cysts. Age at presentation was the only factor discriminating these patients from patients with idiopathic intussusception. Unlike previous studies, duration of symptoms was not useful in identifying a pathological leadpoint. Hydrostatic reduction was successful in reducing the leadpoint in three of 21 attempts. Neither morbidity nor mortality was encountered in a policy of initial enema reduction of intussusception, regardless of age.
