THE NEW method of visualizing the bile ducts by the oral administration of radiopaque material has proved of diagnostic value in two types of biliary tract conditions previously resistant to any form of roentgenologic diagnostic procedure.1 These are (1) the apparently nonfunctioning gall bladder, as shown by routine cholecystography, and (2) the postcholecystectomy syndrome,2 in which only the recently devised intravenous cholangiography with sodium iodipamide (sodium N, N1-adipyl-bis[3-amino-2, 4, 6-triiodobenzoate]; Biligrafin; Cholografin) has been of diagnostic value. 3-3e
In patients showing no visualization of the gall bladder in the cholecystograms, oral cholangiograms have shown in some cases visualization of the gall bladder, at times with stones. In the nonvisualized gall bladder with cystic duct obstruction, it has been possible by oral cholangiography to visualize pathologic common bile ducts, sometimes with stones. In the postcholecystectomy syndrome, there have been revealed pathologic dilated common bile ducts, common duct
