Endoscopic treatment of a bronchobiliary fistula due to complicated hydatid cyst after surgical intervention: a case report

Hydatid cyst is an infectious parasitic disease often caused by Echinococcus granulosus, or to a lesser extent by Echinococcus alveolaris. The liver is the organ most frequently involved. We report a case with hydatid cyst of the liver and lung that many years after surgery developed bronchobiliary fistula and biloptysis. The patient had been operated 2 times previously but yet the problem was present. Endoscopic retrograde cholangiopancreatography [ERCP] was used successfully for treatment. We present the result of ERCP and endoscopic sphincterotomy in the management of biliary hydatid disease. Bronchopleural fistula after hydatid cyst surgery could be cured by ERCP and sphincterotomy with or without stent insertion
