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

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.Patients and methodsThis study was a retrospective analysis of a prospective registry of patients with malignant drainage stenosis of the hilum. The quality of drainage was evaluated based on the percentage of liver segments drained, which was calculated by dividing the number of liver segments drained by the total number of liver segments. Drainage could be achieved via an endoscopic, EUS-guided or percutaneous route not associated with the procedure.ResultsSixty patients (38 men) were included from Janua...
