- W2893048740 abstract "More 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.This 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.Sixty patients (38 men) were included from January 2015 to July 2016. The mean patient age was 69.84 years. Stenosis was classified as type II for 17 (29%) patients, type III for 20 (34%) patients, and type IV for 22 (37%) patients. Histology revealed cholangiocarcinoma for 26 (43%) patients, metastatic disease from colorectal cancer for 15 (25%) patients and another cancer for 19 (32%) patients. The median survival time was five (2.3-12.3) months.The percentage of liver segments drained had a significant prognostic impact on overall survival regardless of the technique used to drain the liver. The percentage of liver segments drained was dichotomized based on a threshold value of 80%, resulting in two groups (<80% and ≥80%). Univariate analysis of overall survival revealed that the patients with <80% of liver segments drained had significantly worse prognoses (hazard ratio (HR) = 3.25 (1.66-6.36), p < 0.001) than the patients with ≥80% of liver segments drained. This effect was confirmed in multivariate analysis (HR = 2.46 (1.16-5.23), p = 0.02).The other factor that affected survival was invasion of <50% of the liver by the tumor.A receiver operating characteristic curve was used to establish a correlation between patients receiving chemotherapy and the percentage of liver drained (area under the curve = 0.77 (0.65-0.88)).The survival of patients with malignant stenosis of the biliary confluence is highly correlated with the percentage of liver segments drained, regardless of the technique used." @default.
