Roentgenography of the bile ducts.

Cholangiography

 

roentgenographic examination of the gallbladder and bile ducts after the introduction (orally or intravenously) of an iodine-containing contrast agent that is excreted with bile. The procedure is not applied in the case of pronounced jaundice. Cholangiography yields a clear picture of the anatomical structure and functioning of the gallbladder and bile ducts; it reveals the presence of calculi, or gallstones (cholelithiasis), inflammatory changes (cholecystitis or cholangitis), and disruption of the emptying mechanism of the bladder (dyskinesia).

It may help surgeons to confirm the biliary anatomy before dividing any ductal structures, and thus prevent BDI, or to confirm BDI intraoperatively.[12],[13] However, routine use of IOC is still under debate.[14],[15] Many techniques have been developed for biliary tract evaluation, such as laparoscopic ultrasonography, dye cholangiography, and near-infrared fluorescence cholangiography.[16] Many comparative studies are still ongoing to determine whether these techniques are superior in regard to safety, accessibility, ease of interpretation, and radiation exposure.
