Endoscopic approach to benign biliary obstruction

During the past 30 years, the endoscopic approach to benign biliary strictures (BBS) became the preferred “mini-invasive” treatment modality for benign diseases . Endoscopic plastic or metallic stenting, and balloon dilation represent the gold standard treatment for BBS. Side-by-side insertion of multiple plastic stents is a very effective treatment option for BBS following cholecystectomy or liver transplantation . This strategy has a low recurrence rate on long-term follow-up, with better results than fully covered self-expandable metal stents (FC-SEMS). FC-SEMS seems to have an advantage and higher stricture resolution rate in patients with BBS secondary to chronic pancreatitis . Dilation of dominant biliary strictures in patients with primary sclerosing cholangitis has a lower rate of infective complications than the stenting treatment. Endoscopic retrograde cholangiopancreatography represents a safe and effective approach to BBS, with a very high success rate, especially when such cases are managed in a multidisciplinary setting.
