The causes of benign biliary stricture (BBS) include chronic pancreatitis, surgical injury, Mirizzi syndrome, IgG4-related sclerosing cholangitis, and primary sclerosing cholangitis. Endoscopic treatment, medication such as steroid, or surgical treatment is performed according to the etiology of BBS. As for endoscopic treatment, dilation of a biliary stricture using a balloon/bougie catheter followed by biliary stenting is a standard technique. Placement of multiple plastic stents, 10Fr in diameter, side by side for up to 12 months has become the current standard care for the majority of BBS. Recent studies have demonstrated that placement of a fully covered metal stent has similar success rate to multiple plastic stent therapy, with fewer procedures. The developments of balloon enteroscopy and interventional EUS contribute to widespread of endoscopic treatment for BBS. Surgical treatment should be considered for difficult or refractory cases of endoscopic therapy.
