Common Bile Duct Obstruction Due to Candidiasis

Abstract

Biliary obstruction with its wide range of potential causes (e.g. neoplastic lesions, gallstones and inflammatory processes) is a common disease in gastroenterology. Although infections with Candida and other fungal species have increasingly been recognized in patients with certain predispositions, fungal involvement of the biliary tract is extremely rare. We report the case of a male patient with a past history of long-time mechanical ventilation and who was referred to our department with cholangitis. Endoscopic retrograde cholangio-pancreatography (ERCP) of the septic patient revealed a high-degree stenosis of the distal common bile duct with a prestenotic dilation which was strongly suspicious of an underlying malignancy. Control ERCP revealed a beads-like deformation of the intra- and extrahepatic bile duct system which was compatible with chronic secondary sclerosing cholangitis. Examining the bile duct system with a balloon catheter, a long tubular, filamentous structure with several branches at its sides could be extracted and was assessed histologically to be a Candida conglomerate. Candida colonization of the bile duct was confirmed by microbiological analysis of aspirated bile.
