研究目的:

ERCP 引导下胆管支架置入术是治疗晚期恶性远端胆管狭窄的首选治疗方法,新研发的新型抗菌涂层支架旨在具备传统塑料、金属和纳米银等胆管支架的优势。故本研究目的是验证新型抗菌涂层支架治疗恶性远端胆管狭窄的有效性和安全性,即支架通畅时间、技术成功率、治疗成功率、术后不良事件发生率、患者生存时间等。  

Objectives of Study:

ERCP-guided bile duct stenting is the treatment of choice for the treatment of advanced malignant distal bile duct stenosis, and the newly developed new antimicrobial-coated stent is designed to have the advantages of traditional plastic, metal, and nano-silver bile duct stents. Therefore, the purpose of this study is to verify the efficacy and safety of a new antimicrobial-coated stent in the treatment of malignant distal bile duct strictures, namely, stent patency time, technical success rate, treatment success rate, incidence of postoperative adverse events, and patient survival time.
