Acute Colonic Pseudo-Obstruction (Ogilvie Syndrome) in Children
Pediatric Ogilvie Syndrome: Definition and Context
Pediatric Ogilvie Syndrome (Acute Colonic Pseudo-Obstruction, ACPO) is a rare but significant disorder characterized by massive colonic dilatation without mechanical obstruction in children. While less common than in adults, its recognition in pediatric populations is crucial due to unique presentation and management challenges.
Pediatric Epidemiology
Key epidemiological features in children:
- Age Distribution:
- Most common in school-age children (6-12 years)
- Rare but reported in infants and toddlers
- Increased incidence in adolescents with predisposing conditions
- Risk Populations:
- Children with neurological disorders
- Post-operative pediatric patients
- Oncology patients undergoing chemotherapy
- Children with severe systemic infections
Pediatric-Specific Risk Factors
- Primary Conditions:
- Spinal cord disorders
- Severe trauma
- Post-infectious states
- Kawasaki disease
- Childhood oncological conditions
- Iatrogenic Factors:
- Pediatric medications affecting gut motility
- Post-surgical states common in children
- Extended immobilization
Pediatric-Specific Pathophysiology
Developmental Considerations
- Age-Related Factors:
- Immature enteric nervous system
- Developing autonomic nervous system
- Age-specific gut motility patterns
- Unique inflammatory responses in children
- Pediatric Neuromuscular Development:
- Ongoing maturation of gut-brain axis
- Development of intestinal smooth muscle
- Evolving gastrointestinal motility patterns
Pediatric-Specific Triggers
- Medical Conditions:
- Viral gastroenteritis
- Pediatric post-infectious states
- Childhood neurological disorders
- Pediatric oncological treatments
- Common Pediatric Medications:
- Anti-emetics
- Chemotherapeutic agents
- Neuropsychiatric medications
