title: Benign biliary strictures: current endoscopic management.
abstract: Endoscopic treatment is the mainstay of therapy for benign billiary strictures, and surgery is reserved for selected patients in whom endoscopic treatment fails or is not feasible. The endoscopic approach depends mainly on stricture etiology and location, and generally involves the placement of one or multiple plastic stents, dilation of the stricture(s), or a combination of these approaches. Knowledge of biliary anatomy, endoscopy experience and a well-equipped endoscopy unit are necessary for the success of endoscopic treatment. This Review discusses the etiologies of benign biliary strictures and different endoscopic therapies and their respective outcomes. Data on newer therapies, such as the placement of self-expandable metal stents, and the treatment of biliary-enteric anastomotic strictures is also reviewed.
