    Abstract:
    BACKGROUND/AIMS: To assess the feasibility and efficacy of combined T/Y biliary stent for the bilateral drainage of biliary obstruction caused by Bismuth-Corlett type IV hilar cholangiocarcinoma. METHODOLOGY: Eleven patients with unresectable malignant hilar biliary obstruction of Bismuth-Corlett type IV underwent placement of combined T/Y biliary stent. After unilateral or bilateral percutaneous transhepatic cholangiography, “T” or “Y” type combined biliary metal stents were placed based on the intersection angle of the left and right intrahepatic bile ducts. RESULTS: Technical success of stent placement was achieved for all 11 cases. Eight patients had “T” type and three cases had “Y” type stents placement. Internal drainage achieved with no major complications developed, except for minor hemorrhage occurred for two patients (18.2%). The survival time, liver function including bilirubin concentration and degree of dilation of the bile duct improved. CONCLUSIONS: The combined T/Y biliary stent may be feasible and effective for bilaterally drainage of malignant hilar biliary obstruction, this operation is easy to perform, less invasive and shows a good effect of biliary drainage.
