Intimal hyperplasia within biliary Wallstents: failure of recanalisation by insertion of a second endoprosthesis

We report two patients with benign biliary strictures in whom we attempted recanalisation of metallic biliary endoprostheses, occluded by intimal hyperplasia, by the insertion of further endoprostheses within the occluded stents.

Description
Summary:	We report two patients with benign biliary strictures in whom we attempted recanalisation of metallic biliary endoprostheses, occluded by intimal hyperplasia, by the insertion of further endoprostheses within the occluded stents. Initial technical success was achieved in deploying the stents and restoring patency with elimination of mural filling defects. However, we found the intimal hyperplasia to be restrained for less than 48 h. From our initial results it appears that biliary metallic stent occlusion by intimal hyperplasia is not effectively treated by insertion of a second endoprosthesis.
