TRANSHEPATIC CHOLANGIOGRAPHY.
Percutaneous transhepatic cholangiography is a method of visualizing the biliary tree by the injection of radio-opaque medium through the abdominal wall and liver into an intrahepatic bile duct. The procedure is indicated in the immediate preoperative evaluation of patients with obstructive jaundice of unknown etiology and is usually diagnostic in these cases. It may also be of value in avoiding operation in poor-risk patients with obstructive jaundice. Biliary leak resulting in chemical peritonitis is a complication in about 5% of these procedures. Intraperitoneal hemorrhage is a complication in less than 1%. Death results from the procedure in less than 0.5% of cases. Transhepatic cholangiography during surgical operation is of value in demonstrating obstructive lesions of the bile ducts. However, preoperative percutaneous transhepatic cholangiography is preferred, since it makes possible adequate preparation for technically difficult repairs and resections.
