Benign biliary strictures are often a consequence of iatrogenic injury during laparoscopic cholecystectomy or they may arise after liver transplantation or hepatic resection with duct-to-duct biliary anastomosis. Other etiologies of benign biliary strictures are primary sclerosing cholangitis, chronic pancreatitis, and autoimmune cholangitis. In the past, surgical repair was the treatment of choice. Today, ERCP has a pivotal role in the treatment of the vast majority of these lesions. Up to 80% of postoperative benign biliary strictures develop within 6 to 12 months after surgery with symptoms as pruritus, jaundice, abdominal pain, alterations of liver function tests and recurrent cholangitis. Prompt identification of these lesions is essential because long-standing cholestasis can lead to secondary biliary cirrhosis. MRCP with cholangiographic sequences is the preferred non-invasive method for diagnostic cholangiography. In particular, this imaging method can be useful in hilar strictures and in patients with suspected anastomotic biliary stricture after liver transplantation.
