Secondary sclerosing cholangitis

Secondary sclerosing cholangitis abbreviated as (SSC) is a disease that is morphologically similar to primary sclerosing cholangitis (PSC) but that originates from a known pathological process. Its clinical and cholangiographic features may mimic PSC, yet its natural history may be more favorable if recognition is prompt and appropriate therapy is introduced. Thus, the diagnosis of PSC requires the exclusion of secondary causes of sclerosing cholangitis and recognition of associated conditions that may potentially imitate its classic cholangiographic features. Secondary causes of SSC include intraductal stone disease, surgical or blunt abdominal trauma, intra-arterial chemotherapy, and recurrent pancreatitis.^[1] It has been clearly demonstrated sclerosing cholangitis can develop after an episode of severe bacterial cholangitis.^[2] Also it was suggested that it can result from insult to the biliary tree by obstructive cholangitis secondary to choledocholithiasis, surgical damage, trauma, vascular insults, parasites, or congenital fibrocystic disorders. Additional causes of secondary SC are toxic, due to chemical agents or drugs.^[3]
