Association of covered metallic stents with cholecystitis and stent migration in malignant biliary stricture

CSEMSs and USEMSs have similar clinical success rates and patency durations in management of malignant bile duct stricture. CSEMSs, however, are associated with increased rates of migration and cholecystitis. Comparable efficacy and superior safety profile of USEMSs render a compelling argument for its place as the preferred choice of SEMSs in the management of malignant biliary stricture.
