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.
我们报告了两名患有良性胆管狭窄的患者，在这两名患者中，我们尝试通过在闭塞的支架内插入更多的内支架来重新打通被内膜增生阻塞的金属胆管内支架。在部署支架并通过消除壁内充盈缺损恢复通畅方面取得了初步技术成功。然而，我们发现内膜增生仅在不到48小时内受到抑制。从我们的初步结果来看，通过插入第二个内支架并不能有效治疗内膜增生导致的胆管金属支架闭塞。
