Percutaneous Transhepatic Cholangioplasty to Treat Multiple Intrahepatic Biliary Strictures After Hepatoportoenterostomy.

In children with biliary atresia, hepatoportoenterostomy (HP) is recommended to improve bile flow. Biliary strictures are known potential complications after HP, which can again impair bile flow often leading to biliary cirrhosis and liver transplantation. In patients who are status post HP and have biliary strictures, nonsurgical therapeutic options such as endoscopic dilation can pose technical difficulties due to altered anatomy. Percutaneous transhepatic cholangiography with cholangioplasty is a valuable tool for obstructive cholangiopathies, but to our knowledge this has not been previously demonstrated to be successful in patients with multiple intrahepatic biliary strictures status post HP. Herein, we present 3 patients status post HP who presented with multiple intrahepatic biliary strictures and underwent successful percutaneous transhepatic cholangiography with cholangioplasty.
