Insights
Pediatric intussusception cases are rarely caused by isolated ileal heterotopic pancreas. This study reports three new pediatric cases of this rare condition, highlighting its clinical significance.
Area of Science:
- Gastroenterology
- Pediatric Surgery
Background:
- Pediatric intussusception is typically idiopathic, with pathological lead points identified infrequently.
- Meckel's diverticulum is the most common pathological lead point in pediatric intussusception.
- Heterotopic pancreas is most often found in the stomach or duodenum; ileal locations are rare.
Observation:
- Ileal heterotopic pancreas typically presents secondary to Meckel's diverticulum, potentially causing intussusception.
- Isolated heterotopic pancreas in the ileum is exceptionally rare and often an incidental surgical finding.
- Literature review revealed limited pediatric cases of isolated ileal heterotopic pancreas causing intussusception.
Findings:
- This report details three additional pediatric cases of isolated ileal heterotopic pancreas causing intussusception.
- The study contributes to the scarce literature on this specific etiology of pediatric intussusception.
Implications:
- Understanding this rare entity is crucial for accurate diagnosis and management of pediatric intussusception.
- Highlights the importance of considering unusual lead points in pediatric intestinal obstruction.
- Further research may elucidate the pathogenesis and optimal treatment strategies for isolated ileal heterotopic pancreas.
Abstract:
Pediatric intussusception is usually idiopathic in origin, and a pathological lesion at the leadpoint is identified in only a small proportion of cases. Meckel's diverticulum is the most common location when such a lesion is found. Heterotopic pancreas has been seen most frequently in the stomach or duodenum; however, ileal lesions are rare. In the ileum, heterotopic pancreas is usually associated with Meckel's diverticulum and may cause intestinal obstruction by intussusception. However, isolated heterotopic pancreas in the ileum is distinctly rare and usually discovered incidentally during surgery for other conditions. In a review of English language literature, there were only a few pediatric cases of isolated ileal heterotopic pancreas causing intussusception. We report three additional pediatric cases and discuss the clinical significance of this unexpected rare entity.
