Do patients with trisomy 18 (Edward syndrome) have swallowing problems?

Yes, patients with Edwards syndrome (trisomy 18) consistently experience significant swallowing problems that require feeding support.

Feeding challenges are a hallmark feature of trisomy 18, occurring even in the absence of gastrointestinal anomalies, and gastrostomy tube placement is one of the most common surgical procedures needed in the neonatal period 1. These swallowing difficulties are so prevalent that they fundamentally shape the clinical management of these patients.

Clinical Manifestations of Feeding Problems

The feeding difficulties in Edwards syndrome are multifactorial and severe:

• Aspiration risk is substantial, as evidenced by aspiration pneumonia being a common complication requiring hospitalization 2
• Enteral nutrition is consistently required due to the persistent nature of feeding problems 3
• Gastroesophageal reflux commonly complicates feeding, making management decisions more complex 1

Management Approach

The 2025 Pediatrics clinical guidance provides a clear algorithmic approach 1:

1. Initial support: Infants can be supported with nasogastric or nasojejunal feedings early in the hospital course while other medical issues are addressed
2. Timing of gastrostomy tube: This decision should be coordinated with other necessary surgeries if performed early, OR can be delayed until later in hospitalization
3. Home discharge option: Discharge with nasogastric/nasojejunal feedings is feasible if appropriate support exists
4. Transition criteria: Consider gastrostomy tube placement when longer-term survival becomes more likely

Critical Pitfalls

The swallowing problems in trisomy 18 are compounded by:

• Upper airway obstruction, which is more common than historically recognized and contributes to feeding difficulties 3
• Respiratory insufficiency from hypoventilation and aspiration risk 3
• Central apnea that can complicate feeding attempts 1

Families must be counseled that surgical interventions for feeding access (gastrostomy tubes) carry prolonged hospital stays and increased anesthesia/intubation risks in this population 1. The decision to pursue surgical feeding access should balance these risks against the benefits, particularly given the higher surgical morbidity and mortality in infants with trisomy 18 1.

The feeding challenges are so consistent that they represent a core feature requiring proactive management planning from the neonatal period onward, regardless of whether structural gastrointestinal anomalies are present 1, 3.
