Esophageal Stenosis

What Is Esophageal Stenosis?

Esophageal stenosis refers to a narrowing of the esophagus — the muscular tube that carries food and liquids from the mouth to the stomach. This condition can make swallowing difficult or painful and may cause food to become stuck. Esophageal stenosis can occur at any age but is especially significant in infants and children when caused by congenital abnormalities.

In adults, esophageal stenosis is often due to scar tissue, inflammation, or growths, while in pediatric patients, it may result from congenital defects, prior surgery, or ingestion of corrosive substances.

Causes of Esophageal Narrowing

Esophageal stenosis can be caused by a range of conditions, including:

  • Congenital esophageal stenosis (present at birth)
  • Acid reflux leading to scarring and narrowing (peptic stricture)
  • Radiation therapy or chemotherapy
  • Ingestion of caustic chemicals (accidental or intentional)
  • Esophageal tumors
  • Post-surgical scar formation

Signs and Symptoms

Symptoms can vary depending on the severity of the narrowing but may include:

  • Difficulty swallowing (dysphagia), especially with solid foods
  • Food getting stuck in the throat or chest
  • Chronic vomiting or regurgitation
  • Poor weight gain or feeding issues in infants
  • Heartburn or chest discomfort

In infants and young children, feeding difficulties and aspiration (food entering the lungs) may be the earliest signs.

How It’s Diagnosed

Diagnosis of esophageal stenosis involves a combination of clinical evaluation and imaging studies:

  • Barium swallow study to visualize the narrowed area of the esophagus
  • Upper endoscopy (EGD) to examine the esophageal lining and take biopsies if needed
  • Esophageal manometry to assess motility or function of the esophagus (in some cases)

Treatment Options

Treatment depends on the cause and severity of the stenosis. Options may include:

  • Endoscopic dilation — a procedure that stretches the narrowed area using balloons or dilators
  • Surgical resection or reconstruction in cases where the stenosis is severe or recurring
  • Stent placement to keep the esophagus open in certain complex cases
  • Medications such as proton pump inhibitors if acid reflux is a contributing factor

In pediatric cases, long-term follow-up may be necessary to monitor feeding, growth, and recurrence.

Frequently Asked Questions

It can be congenital or acquired due to surgery, acid reflux, or ingestion of corrosive substances. Congenital cases are often diagnosed early due to feeding problems.

Most cases are managed with endoscopic dilation. Severe or recurrent cases may require surgery to remove or bypass the narrowed segment.

No. Atresia is a complete blockage or discontinuity of the esophagus, typically present at birth. Stenosis refers to narrowing, which may be partial and can develop over time.

Symptoms include trouble swallowing, vomiting, poor weight gain, or food getting stuck. Infants may struggle with feeding or experience respiratory symptoms from aspiration.
