ABSTRACT
BACKGROUND/AIMS:
Hilar cholangiocarcinomas have an extremely poor prognosis. Although endoscopic bilateral metal stenting with the "stent in stent" technique using a Y stent is currently employed to treat patients with an unresectable hilar cholangiocarcinoma, this method has limited application in cases of tight strictures. Furthermore, insertion of stents into the Y stent side (first stent side) is problematic in cases of tumor recurrence. We evaluated the clinical efficacy of the use of endoscopic bilateral metal stenting with the Zilver stent.METHODS:
Seven patients with an unresectable Bismuth type III or IV hilar cholangiocarcinoma were included in this study. For endoscopic bilateral metal stenting, we first inserted a Y stent with a central wide-open mesh. The Zilver stent was placed into the contralateral hepatic duct through the central portion of the Y stent.RESULTS:
Both technical and functional success was achieved in seven patients (100%). The early complication rate was 0%, and late complications due to tumor recurrence occurred in 2 out of 7 (28.6%) patients. These patients were managed by the placement of additional stents or with the use of percutaneous transhepatic biliary drainage.CONCLUSIONS:
We suggest that a combination technique using Y and Zilver stents improves bilateral stenting for patients with advanced hilar cholangiocarcinoma and facilitates stent reinsertion in cases of tumor recurrence.
