title: LP-X in cholestasis.
abstract: Extrahepatic and intrahepatic biliary obstruction of different etiology were studied in 62 patients, who were investigated for the presence of lipoprotein X (Lp-X). It was found present in 19 of 20 cholestasis by lithiasis, in all three primary biliary cirrhosis patients, in 2 of 4 cirrhosis, in 5 of 13 hepatitis, in all three benign recurrent intrahepatic cholestasis and in 1 of 2 recurrent juandice of pregnancy. It was found in a Dubin Johnson. Lp-X disappeared in 4 patients within two weeks after relief of the obstruction. It was found in patients with cholestatic hepatitis during the first week of jaundice. It was found in the first 48 hours in three patients with cholestasis by lithiasis. Lp-X does not help in differential diagnosis between extrahepatic and intrahepatic biliary obstruction, but the time of its appearance could contribute to it in some cases. A word of caution is raised in indicating surgery in a cholestatic patient without the presence of Lp-X.
