Left lobe of the liver: percutaneous biliary drainage

Left-sided biliary drainage was performed in 89 of 678 (13%) patients undergoing percutaneous biliary drainage procedures during a 9-year period. The most common indication was Klatskin tumor, followed by sclerosing cholangitis, carcinoma of the gallbladder, postoperative benign stricture, and metastasis to the porta hepatis. Left-duct drainage was successful in 82 of the 89 patients (92%) in whom it was attempted. One patient sustained a major hemorrhage from a hepatic artery aneurysm, which was managed with transcatheter embolization.
