Endoscopic hemostasis using temporary covered biliary wallstent for postsphincterotomy bleeding (report of two cases)

Introduction: Endoscopic sphincterotomy (ES) is an established procedure for accessing the biliopancreatic ductal system for therapeutic intervention in ERCP. ES induced hemorrhage is a serious complication and established endoscopic treatments include temporary local balloon tamponade, injection and thermal therapy.
