Esophageal Atresia X-ray: Radiographic Signs:

Esophageal Atresia X-ray:

Other Cases: Radiological cases of Surgery

It is a congenital condition that can be identified through radiographic findings. Key indicators include:

• Dilated Pharyngeal Pouch: The X-ray may reveal a distended pharyngeal pouch.
• Distal Fistula Indication: The presence of air in the stomach and bowel alongside esophageal atresia suggests a distal fistula.
• Feeding Tube Placement: If a feeding tube has been attempted, the X-ray might show the tube looping back in the upper thorax or entering the trachea/bronchial tree.

What is Esophageal Atresia?

It is a birth defect where a baby’s esophagus (food pipe) doesn’t connect properly to the stomach. Instead, it ends in a pouch, making swallowing impossible. This condition occurs when the Congenital foregut fails to separate into the trachea (windpipe) and esophagus during early fetal development (around 4 weeks gestation).

It’s the most common congenital esophageal anomaly, affecting 1 in 3,000-4,500 newborns. About 50-75% of cases occur alongside other birth defects, making early diagnosis crucial.

Associated Conditions and Risk Factors

Many infants with this condition have additional abnormalities:

Common Associated Conditions

• VACTERL association (Vertebral, Anal, Cardiac, Tracheo-Esophageal, Renal, Limb defects)
• CHARGE syndrome
• Other intestinal atresias (duodenal, jejunoileal, or anal)
• Annular pancreas
• Pyloric stenosis

Genetic Factors

• Trisomy 21 (Down syndrome)
• Trisomy 18 (Edwards syndrome)
• Most cases are sporadic (no clear genetic cause)

Possible Risk Factors

• Maternal antithyroid drug use in early pregnancy
• Environmental teratogens (substances that disrupt fetal development)

Symptoms and Diagnosis of Esophageal atresia

Clinical Signs in Newborns

• Excessive drooling (inability to swallow saliva)
• Choking/coughing during feeding
• Failed nasogastric tube insertion (tube coils back in the esophagus)
• Respiratory distress (due to aspiration)

Prenatal Ultrasound Findings

• Small or absent stomach bubble
• Polyhydramnios (excess amniotic fluid)
• Growth restriction in severe cases

Types of Esophageal Atresia

The condition is classified based on anatomical variations and the presence of a tracheoesophageal fistula (TEF):

Diagnostic Imaging of Esophageal atresia

1. X-ray Findings of Esophageal atresia

• Dilated upper esophageal pouch
• Air in stomach (if a distal fistula exists)
• Coiled feeding tube in the chest

2. Fluoroscopy (Contrast Study)

• “Blind-ending” esophagus (contrast pools in the pouch)
• TEF detection (contrast entering the trachea)

3. Ultrasound & CT

• Prenatal ultrasound may suggest the condition
• CT scans help assess complex cases (not routine)

Treatment and Surgery of Esophageal atresia

Surgical Repair (Primary Goal)

• Reconnect the esophagus (primary anastomosis)
• Close any fistulas to prevent aspiration
• Gastrostomy tube may be needed for feeding

Prognosis Factors

• Depends on associated anomalies (heart defects worsen outcomes)
• Gap length between esophageal ends affects surgical success
• Long-term complications may include:
  • Strictures (narrowing)
  • Gastroesophageal reflux (GERD)
  • Swallowing difficulties

Key Takeaways

✅ Most common type (85%) is proximal atresia + distal fistula
✅ Diagnosed via X-ray, fluoroscopy, or prenatal ultrasound
✅ Surgery is required to reconnect the esophagus
✅ VACTERL association is common (check for other defects)
✅ Long-term follow-up is needed for complications
