Late dumping syndrome in an infant on feeding jejunostomy

Area of Science:

• Pediatric Gastroenterology
• Metabolic Disorders

Background:

• Jejunostomy tube feeding is used for infants with failure to thrive and gastroesophageal reflux.
• Dumping syndrome is a known complication of gastric surgery in adults, rarely reported in children.

Observation:

• A 3-month-old infant on bolus jejunostomy feeds developed recurrent hyperinsulinemic hypoglycemia.
• These episodes occurred despite appropriate caloric intake, suggesting a feeding-related metabolic disturbance.

Findings:

• The infant was diagnosed with late dumping syndrome, characterized by postprandial hypoglycemia.
• Management involved transitioning from bolus to continuous jejunostomy feeds and eliminating added sugars.

Implications:

• This case highlights late dumping syndrome as a rare but significant cause of hypoglycemia in infants receiving jejunostomy feeds.
• Continuous infusion and dietary modifications can effectively manage this condition in pediatric patients.
