Obstruction of the left hepatic duct: diagnosis and treatment by selective fine-needle cholangiography and percutaneous biliary drainage.
Obstruction of the left hepatic duct due to periportal pathologic conditions was identified by fine-needle transhepatic cholangiography in 28 patients. Selective cholangiography of the left duct was performed in 30 instances and subsequent selective left-sided catheter decompression was carried out in 23 cases. Techniques for selective puncture and drainage of the left duct required procedure modifications to accommodate the specific anatomic and pathologic features of the obstructed left duct system. Ultrasonography was indispensable as an aid to delineation of the left duct anatomy for directing needle puncture. Accurate documentation and successful catheter drainage of left duct obstruction are important contributions to the total management of patients with high biliary obstruction.
