Symptoms of an anal fistula?

What are the causes and symptoms of tracheoesophageal fistula?

• Answer:

  Tracheoesophageal fistulas arise as a developmental abnormality. At birth, the infant has difficulty swallowing. Eating produces severe coughing spells that interfere with breathing. Aspiration pneumonia can develop from fluid breathed into the lungs. Small H type fistulas may go undiagnosed until later in life. Symptoms of an H type fistula include frequent pulmonary infections and bouts of abdominal bloating. Source: The Gale Group. Gale Encyclopedia of Medicine, 3rd ed.";
