Congenital bronchobiliary fistula: A case report and review of the literature

BACKGROUND: Congenital bronchobiliary fistula is a rare developmental abnormality with an abnormal fistula between the respiratory system and biliary tract. The aim of this report is to analyze and summarize the clinical features and experience of diagnosing and treating congenital bronchobiliary fistula (CBBF) occurring in the neonatal period. CASE SUMMARY: The onset of symptoms was 3 d after birth in our patient with progressive cyanosis and respiratory distress, and a large amount of green fluid was noticed in her respiratory secretion. We performed computed tomography (CT), fiberoptic bronchoscopy, and cholangiography to make a diagnosis, as well as fistulography with a bronchoscope for the first time. These examinations provided us with valuable images to make a correct diagnosis. The fistula was dissected and removed with excellent results. Surgical removal of the fistula was successful, and the baby recovered well and was discharged. She has been followed for 4 mo without any signs of discomfort. CONCLUSION: The main symptom of CBBF is bile-like sputum. CT, bronchoscopy, fistulography, and intraoperative cholangiography can provide important evidence for diagnosis. Surgical resection of the fistula is the first choice of treatment.
