[Endoscopic management of benign biliary strictures].

Endoscopic management of benign biliary strictures has significantly changed in recent years. Excluding a malignant etiology remains the first, critical, step; significant progress is being made to increase diagnostic accuracy of bile duct stricture sampling, although negative predictive value does not reach 100%. The currently preferred treatment consists of stricture dilation followed by placement of multiple temporary plastic stents. Drawbacks of this technique include repetition of endoscopic procedures and a small risk of cholangitis. Larger diameter covered self-expandable metal biliary stents seem to be a promising alternative. In this review, we will discuss the various etiologies of benign biliary strictures, their clinical presentation, the diagnostic tools and the endoscopic treatment.
