Palliative endoscopic drainage of malignant stenosis of biliary confluence: Efficiency of multiple drainage approach to drain a maximum of liver segments

摘要

Background and aimMore than 50% of the liver should be drained in case of unresectable hilar liver stenosis; however, it remains unclear if the use of several types of drainage (endoscopic retrograde cholangiography and pancreatography, percutaneous-biliary drainage, endoscopic ultrasound biliary drainage (EUS-BD)), allowing better drainage, has an impact on survival. The aim of our study was to evaluate the percentage of liver drained and its correlation on survival whatever the drainage technique used.
