A Case of Biliary Cast Syndrome After Endoscopic and Percutaneous Management of Common Bile Duct Stone

Biliary cast syndrome is an unusual complication in patients who have previously undergone liver transplantation. It occurs in approximately 5%–18% of such patients. Rare cases of biliary cast syndrome in patients without liver transplants have also been reported. The pathogenesis of biliary cast has not been clearly identified, although etiologic factors including post-transplant bile duct damage, ischemia, biliary infection, and presence of a post-operative biliary drainage tube have been proposed. Here we present a case of biliary cast that developed in a 49-year-old male who underwent a non-liver surgery after endoscopic and percutaneous management of common bile duct stone.
