Living with Congenital bronchobiliary fistula

A rare condition present from birth in which the windpipe or a bronchus connects to a bile duct of the liver.

Understanding Congenital bronchobiliary fistula

Congenital bronchobiliary fistula is a rare developmental condition in which the airway has an abnormal connection to the liver's bile duct.

The windpipe (trachea) or a bronchus connects with the left hepatic duct. It can cause breathing difficulty, repeated respiratory infections, and bile in coughed-up material or vomit. It is seen in childhood.

Signs & symptoms

Symptoms vary from person to person. GARD's summary describes these features:

  • Breathing difficulty
  • Repeated respiratory infections
  • Bile in coughed-up material or vomit
  • Narrowed windpipe (tracheal stenosis)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include digestive system specialists, genetic specialists and lung and breathing specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
