Bilateral stent deployment for malignant biliary obstruction (MHBO) can be achieved using side-by-side (SBS) or stent-in-stent (SIS) procedures. Compared with SBS techniques, the procedural steps of SIS are technically complex due to the necessity of introducing the delivery system into a contralateral biliary tract through the mesh of the SEMS. To overcome this issue, a novel uncovered SEMS, the HILZO Moving Cell Stent (MCS) has been released. The present study examined the technical feasibility of treating MHBO using bilateral deployment of this novel stent without dilating the mesh of the first stent to achieve insertion of the second stent within a single session, using a prospective, multicenter setting.

内镜下多支架置入治疗肝门梗阻移动细胞金属支架的前瞻性多中心评价

恶性胆道梗阻 (MHBO) 的双侧支架部署可以使用并排 (SBS) 或支架内支架 (SIS) 程序来实现。与 SBS 技术相比，SIS 的程序步骤在技术上很复杂，因为需要通过 SEMS 的网格将输送系统引入对侧胆道。为了克服这个问题，一种新颖的未覆盖 SEMS，即 HILZO 移动细胞支架 (MCS) 已经发布。本研究使用前瞻性多中心设置，检查了使用这种新型支架的双侧部署来治疗 MHBO 的技术可行性，而无需扩张第一个支架的网孔以在单个疗程内实现第二个支架的插入。
