Endoscopic Drainage of 50 of Liver in Malignant Hilar Biliary Obstruction Using Metallic or Fenestrated Plastic Stents

摘要

Objectives:Endoscopic drainage of complex hilar tumors has generally resulted in poor outcomes. Drainage of >50% of liver volume has been proposed as optimal, but not evaluated using long multifenestrated plastic stents (MFPS) or self-expanding metal stents (SEMS). We evaluated outcomes of endoscopic drainage of malignant hilar strictures using optimal strategy and stents, and determined factors associated with stent patency, survival, and complications.
