Biliary leaks and strictures are the most frequent complications after HPB surgery. When suspecting a bile leak after liver resection ERCP allows to both confirm and localize the leak and to treat it by sphincterotomy and stent placement. In case of complex strictures and leakage the ideal managements should combine the use of fc-SEMS and plastic stents in order to drain all the biliary branches and prevent cholangitis. Several ERCP sessions and long lasting treatment can be necessary to achieve the complete resolution of a complex stricture.
