Percutaneous Intraductal Ultrasonography Guided Biliary Reconstruction: Single-Stage Management of Indeterminate Biliary Obstruction and Intrastent Stenosis

Abstract Percutaneous transhepatic cholangiography is a useful imaging technique during biliary evaluation and interventions. However, contrast cholangiography alone provides limited information on the nature, quality, or severity of potentially treatable biliary conditions. In this case report, transhepatic intravascular ultrasound is utilized to perform intraductal ultrasonography during complex biliary reconstruction for the evaluation of indeterminate biliary obstruction and management of intrastent stenosis.
