abstract
Biliary stenting is most frequently caused by an interruption in the ability to drain bile into the duodenum. This obstructive jaundice is commonly a result of a stricture from a tumor located at the pancreas’s head, peri-ampulary area, bile duct, or gall bladder. Jaundice can also occur from anastomotic strictures which result from post-surgery biliary complications. In order to restore patency, stenting of the biliary tree is performed by means of endoscopic retrograde cholangiopancreatography (ERCP). There are two main types of stents each having their respective advantages and disadvantages. Unfortunately, nearly 30% of all biliary stents fail and require removal, exchange, or intervention. One common mode of failure is migration, which occurs 17% of the time with fully covered metallic stents.
