Distal bile duct cancers complicated with cholangiobronchopleural fistula after ERCP: A case report

Abstract

Distal (lower) bile duct cancers arise in the lower half of the biliary tree closer to the small intestine. Biliary disease complicated with cholangiobronchopleural fistula, which may occur in cases of multiple hepatobiliary stones or biliary ascariasis-associated severe infection, has rarely been reported in the literature, particularly following endoscopic retrograde cholangiopancreatography (ERCP). The present study describes the case of a 60-year-old female with distal cholangiocarcinoma complicated with cholangiobronchopleural fistula after ERCP for this rare disease. This complication was likely due to the inability to control retrograde infection following ERCP and, thus, the infection was disseminated. This resulted in mixed infection involving the diaphragm and pleura, and further penetrating the bronchus. The patient was managed with pancreatoduodenectomy and has since remained in good health.
