Multicenter study of endoscopic preoperative biliary drainage for malignant hilar biliary obstruction: E‐POD hilar study

Abstract

Our retrospective analysis did not demonstrate the advantage of ENBD over EBS as the initial PBD for resectable hilar MBO. Although the technical success rate of endoscopic PBD was high, its re-intervention rate was not negligible, and unplanned re-intervention was associated with a poor prognosis in resected hilar MBO.
