  • Title: Bilateral internal biliary drainage of hilar cholangiocarcinoma with modified Gianturco Z stents inserted via a single percutaneous tract.

    Journal: J Vasc Interv Radiol; 1993; 4(5):605-10. PubMed ID: 8219552.
    Abstract:
    PURPOSE: Modified Gianturco Z stents were used in five patients with hilar cholangiocarcinoma to permit bilobar hepatic drainage via a single percutaneous tract. PATIENTS AND METHODS: After successful negotiation of strictures from the ipsilateral hepatic duct to the contralateral hepatic duct and the common bile duct, a modified endoprosthesis--made by connecting two double-body Z stents with two stainless steel wires in order to leave a space in between--was implanted in one stricture and a 'space' was located at the hepatic confluence. A second endoprosthesis, a two- to six-body Z stent, was introduced into the second stricture through the 'space' of the initial endoprosthesis and was implanted so that a part of the endoprosthesis should overlap the initial endoprosthesis. RESULTS: Optimal positioning of the two endoprostheses was successful in all patients. CONCLUSION: The technique seems simple, safe, and reliable in reconstructing the bilateral hepatic ductal systems via a single percutaneous approach in patients with hilar cholangiocarcinoma.
