Benign biliary stricture

Benign biliary stricture is an uncommon but challenging clinical condition that requires a multidisciplinary approach for management. The diagnosis of biliary stricture is often missed or delayed because of its indolent course. Benign strictures usually develop due to damage to the bile ducts during surgery or trauma to the abdomen; a recurring condition, such as chronic pancreatitis or cholelithiasis with chronic cholangitis. After the injury, an inflammatory response ensues, which is followed by fibrosis and narrowing of the bile duct lumen. Surgery, the traditional mainstay of treatment for benign biliary strictures is associated with significant morbidity and mortality. Endoscopic treatment of BBS has become widely used in the last decade with the advance of the design of fully covered self expanding metal stents.
