When clinical suspicion is high, performance of either endoscopic retrograde cholangiopancreatography ERCP or percutaneous transhepatic cholangiography PTHC is preferable, depending on the type of anastomosis that was performed and the experience of the center in accomplishment of therapeutic procedures such as dilatations and the use of biliary stents.
Si la sospecha clínica es alta se prefiere la colangiopancreatografía retrógrada endoscópica CPRE o la colangiografía transhepática percutánea CTP dependiendo del tipo de anastomosis realizada y la experiencia del centro, para permitir la realización de procedimientos terapéuticos como dilataciones y el uso de stent biliar.
