Tracheoesophageal fistula is a condition where there is a connection between the trachea (windpipe) and the esophagus.

What Are the Causes of Tracheoesophageal Fistula?

The trachea and the esophagus are in close relationship (esophagus is located behind the trachea). Any disease in the trachea or the esophagus that erodes into the wall of either organ can result in tracheoesophageal fistula.

The most common tracheoesophageal fistula causes include:

  • Complication of intubation (use of a breathing tube of a respiratory machine). The balloon of the breathing tube can erode from the trachea into the esophagus.
  • Cancer of the esophagus, eroding into the trachea.
  • Radiotherapy for treatment of cancer of the neck or chest (radiation-induced tracheoesophageal fistula).

What Are the Symptoms of Tracheoesophageal Fistula?

Food and saliva can enter from the esophagus into the trachea, via the fistula, causes coughing following swallowing, and pneumonia. Other tracheoesophageal fistula symptoms can include dysphagia and choking.

How Is Tracheoesophageal Fistula Diagnosed?

How Is Tracheoesophageal Fistula Treated?

Tracheoesophageal fistulas rarely close spontaneously. The treatment depends on the cause and the location of the fistula. The goal of the therapy is to cover the connection between the trachea and the esophagus to prevent aspiration and pneumonia. The main therapies include esophageal stenting, or surgical repair. The surgical repair includes separation of the trachea and the esophagus, repair of the hole in each organ and placement of a muscle between the two organs to prevent future fistula formation.
