SSC is thought to develop as a consequence of known injuries or pathological processes of the biliary tree, such as biliary obstruction, surgical trauma to the bile duct, or ischemic injury to the biliary tree.<unk>  causes of SSC include intraductal stone disease, surgical or blunt abdominal trauma, intra-arterial chemotherapy, and recurrent pancreatitis. It has been clearly demonstrated that sclerosing cholangitis can develop after an episode of severe bacterial cholangitis. Also it was suggested that it can result from insult to the biliary tree by obstructive cholangitis<unk>  to choledocholithiasis, surgical damage, trauma, vascular insults, parasites, or congenital fibrocystic disorders. Additional causes of<unk>  SC are toxic, due to chemical agents or drugs.
