Role of Interventional Radiology in the Management of Acute Cholangitis

Acute cholangitis presents with a wide severity spectrum and can rapidly deteriorate from local infection to multiorgan failure and fatal sepsis. The pathophysiology, diagnosis, and general management principles will be discussed in this review article. The focus of this article will be on the role of biliary drainage performed by interventional radiology to manage acute cholangitis. There are specific scenarios where percutaneous drainage should be preferred over endoscopic drainage. Percutaneous transhepatic and transjejunal biliary drainage are both options available to interventional radiology. Additionally, interventional radiology is now able to manage these patients beyond providing acute biliary drainage including cholangioplasty, stenting, and percutaneous cholangioscopy/biopsy.
