Abstract

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.
