Abstract:
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.

Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
