Extrahepatic bile duct stones are largely classified into primary and secondary stones. Most extrahepatic bile duct stones are known to migrate from the gallbladder, and thus named secondary stones. Primary stones are formed de novo in the extrahepatic bile duct and are rare. We present an interesting case of a 61 year-old man with obstructive jaundice and biliary sepsis in whom a black extrahepatic bile duct stone and a yellow-to white extrahepatic bile duct stone had been removed during single session of endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy.
