Tracheoesophageal fistula (TEF)

Most common type

Clinical features in a newborn

• Excessive salivation or frothing
• Choking, coughing, cyanosis, or respiratory distress during feeds
• Aspiration pneumonia
• Inability to pass a nasogastric/orogastric tube into the stomach
• Maternal polyhydramnios may be present antenatally

Diagnosis

• Pass a radio-opaque nasogastric tube: in esophageal atresia it stops and coils in the upper esophageal pouch.
• Chest and abdominal X-ray confirms the tube position.
• Gas in the stomach suggests a distal TEF. - Pye's Surgical Handicraft, p. 413
• Echocardiography and renal ultrasound are commonly done because associated anomalies are frequent.

Associations

• Vertebral defects
• Anal atresia
• Cardiac anomalies
• TE tracheoesophageal fistula
• Renal anomalies
• Limb abnormalities

Management

1. Keep the infant nil by mouth.
2. Continuous suction of the upper pouch to reduce aspiration.
3. Position head-up, stabilize airway and breathing, give IV fluids.
4. Treat aspiration or sepsis if present.
5. Pediatric surgical repair: ligation/division of the fistula and primary esophageal anastomosis when feasible.
