• In some patients with biliary obstruction, access to the hepatic hilus is hindered by extensive tumor or by dense vascular scar tissue. In such patients, the biliary tract may be decompressed via the left hepatic duct away from the affected hilus. Access to the left hepatic duct in the left intersegmental plane is gained by dividing the round ligament, freeing it from the undersurface of the liver, and following it to its junction with the left portal vein. The left hepatic duct, which lies superior to the vein, is exposed by dividing the liver overlying the round ligament in the relatively avascular plane between the lateral and the medial segments of the left hepatic lobe. Decompression can be effected by simple tube drainage or, if the duct is large enough, by Roux-en-Y hepaticojejunostomy.
