A 63-year-old woman with compensated HCV-induced liver cirrhosis underwent a right hepatectomy through thoracophrenolaparotomy due to a giant hydatid cyst (segments 6, 7, 8) in 1977, which developed an external biliary fistula complication from 1980 on. Twenty-six years after hepatectomy, at the time of external biliary fistula close, she showed expectoration of bile, and bronchoscopy discovered bile in the bronchial tree. Magnetic resonance cholangiography and percutaneous transhepatic cholangiography showed a common hepatic duct stricture, intrahepatic duct dilation, and bronchobiliary fistula. Due to its benign character, we decided to treat the stricture with dilation and placement of a bile drainage, thus solving the situation.
Bronchobiliary fistula is an uncommon condition usually seen in endemic regions as a complication of hydatid or amoebic disease (4). In Western society, bile obstruction, usually secondary to hepatectomy, is one of the most frequent causative factors (1,3). It may develop from days to years after hepatectomy (1). Bilioptysis is a very specific symptom. On computed tomography and magnetic resonance images, we may usually see both the fistula and the obstruction. Endoscopic retrograde cholangiopancretography and percutaneous transhepatic cholangiography may also allow therapeutic management, so they are considered the techniques of choice (1). The treatment strategy that is common for patients with bronchobiliary fistula and obstruction is the reposition of bile drainage into the duodenum, which allows the fistula to heal by reducing intrabiliary pressure. Surgical approaches should be considered only after failure of less invasive techniques. This is because reoperative procedures tend to be complicated with significant morbidity and mortality (1). Various techniques capable of bile drainage reestablishment are the placement of a nasobiliary drainage (2), endoscopic sphinterotomy, placement of a biliary endoprosthesis (1,3), dilation of stenotic bile duct, and embolization of biliary fistula with diverse embolic materials (coils, Histoacryl) (4).
