Successful Treatment of Bronchobiliary Fistula After Living Donor Liver Transplantation: A Case Report.

A bronchobiliary fistula (BBF), which is defined by abnormal communication between the biliary system and the bronchial tree, is usually regarded as a consequence of local infection, such as hydatid or amebic disease of the liver, hepatic abscess, trauma, neoplasm, and other causes of biliary obstruction. We present a 40-year-old female patient who received a living donor liver transplantation for autoimmune hepatitis and who suffered from biliary stricture at the anastomosis, bile leakage in the right subphrenic region, and development of a BBF 1 year later. Magnetic resonance cholangiography (MRC) and fistulography showed a fistula between the subphrenic biloma and right lower bronchus. The patient was treated successfully by the subphrenic drainage tube and percutaneous transhepatic cholangial drainage (PTCD) crossing the biliary stricture. In conclusion, the BBF is an extremely rare complication after liver transplantation; and minimal-invasive procedures, such as percutaneous drainage and PTCD, are useful for the closure of BBF. This case report is approved by the Institutional Review Board (IRB) of Kaohsiung Medical University Chung-Ho Memorial Hospital, certifying that no prisoners were used in the case and that participants were neither paid nor coerced.
