Severe Primary Sclerosing Cholangitis Biliary Stricture Managed With a Small-Caliber Cardiac Angioplasty Balloon: Looking Outside the Endoscopic Retrograde Cholangiopancreatography Toolbox

Primary sclerosing cholangitis leads to biliary obstruction through a dominant biliary stricture. Endoscopic management of biliary strictures with balloon dilation is preferred over percutaneous radiological or surgical interventions. High-grade biliary strictures can be challenging to manage endoscopically because the traditional endoscopic retrograde cholangiopancreatography accessories fail to traverse these severely stenotic strictures. We describe a case of endoscopic management of a severe primary sclerosing cholangitis-related distal biliary stricture managed with a cardiac angioplasty balloon after failed attempts using the standard endoscopic retrograde cholangiopancreatography accessories and percutaneous radiological intervention.
