The term seems appropriate and I believe it should be used to describe biliary tract bleeding regardless of the etiology. <h3>Historical Review</h3> Of the more than 100 cases of hemobilia reported in the literature, the great majority are caused by rupture of an atherosclerotic aneurysm of the right hepatic artery into the biliary duct system. McNair⁵recently reviewed the world literature and found 12 instances in which ruptured right hepatic artery aneurysms causing hemobilia had been successfully treated. Sandblom⁸has reported 9 cases of subcapsular liver injury that in most instances resulted in hemobilia. Quattlebaum⁶has reported 2 cases in
