背景/目的 使用多枚金属支架（MS）对恶性肝门胆管狭窄进行内镜治疗在技术上要求很高，包括MS的初始展开和通过多枚塑料支架（PS）展开从MS闭塞中恢复。我们评价了Soehendra支架取栓器（SSR）作为顽固性狭窄扩张器的应用结局。 方法 59例恶性肝门胆管狭窄患者使用部分支架中支架手术插入多个MS。当我们遇到顽固性狭窄时，我们采用SSR扩张狭窄和MS的扩张。我们评估了SSR应用后MS或PS部署的成功率和手术并发症。 结果 59例患者中有5例（8%）在初始MS展开时接受SSR应用。MS在所有这些患者中成功展开（100%）。在27例患者中观察到MS闭塞。我们对7名患者（26%）在MS闭塞后展开多个PS时应用SSR。5例患者（71%）在SSR应用后成功展开PS。所有患者均未发生与使用SSR扩张相关的并发症。 结论 SSR被证明是一种有效的扩张器的困难狭窄的恶性肝门部胆管狭窄的管理。
BACKGROUND/AIMS The endoscopic management of malignant hilar biliary strictures using multiple metallic stents (MS) is technically demanding, in the initial deployment of MS and the recovery from MS occlusion with deployment of multiple plastic stents (PS). We evaluated the outcomes of the application of a Soehendra stent retriever (SSR) as a dilator of intractable strictures. METHODOLOGY Fifty-nine patients with malignant hilar biliary strictures had multiple MS inserted using a partial stent-in-stent procedure. When we encountered intractable strictures, we adopted SSR to dilate the stricture and the interstice of the MS. We evaluated the success rate of MS or PS deployment after SSR application and procedural complications. RESULTS Five of 59 patients (8%) were subjected to SSR application for the initial MS deployment. MS were successfully deployed in all of these patients (100%). MS occlusion was noted in 27 patients. We applied SSR to seven patients (26%) for the deployment of multiple PS after MS occlusion. In five patients (71%), successful PS deployment was achieved after the SSR application. No complications related to dilatation using SSR occurred in any patient. CONCLUSIONS SSR proved to be a potent dilator of difficult strictures in the management of malignant hilar biliary strictures.
