Leading points in childhood intussusception.

Area of Science:

• Pediatric Surgery
• Gastroenterology
• Clinical Medicine

Background:

• Intussusception in children can be idiopathic or caused by a specific pathologic lesion.
• Lesion-associated intussusception is often more difficult to diagnose and associated with higher morbidity.
• Over 500 cases of intussusception were reviewed, with 31 identified as lesion-associated.

Purpose of the Study:

• To analyze the clinical characteristics and outcomes of pediatric intussusception cases caused by specific pathologic lesions.
• To identify common leading points and management strategies in lesion-associated intussusception.
• To compare these cases with the idiopathic variety.

Main Methods:

• Retrospective analysis of 31 cases of lesion-associated intussusception within a larger series of over 500 cases.
• Evaluation of patient age, symptom duration, presenting signs, diagnostic methods (barium enema), and surgical interventions.
• Identification of common leading points such as Meckel's diverticula, polyps, and duplications.

Main Results:

• Children with lesion-associated intussusception were older on average, with longer symptom duration.
• Nearly 50% presented with advanced small bowel obstruction.
• Barium enemas were less frequently successful in reduction (0%), and ileo-ileal intussusceptions were more common.
• Meckel's diverticula, polyps, and duplications were the most frequent leading points.
• All patients required surgery, with three-fourths undergoing bowel resection.

Conclusions:

• Lesion-associated intussusception in children presents unique diagnostic and management challenges.
• Older children and those with recurrent intussusception do not always have identifiable leading points.
• Prompt surgical intervention is often necessary for lesion-associated intussusception, with a significant rate of bowel resection.
