Abstract:
BACKGROUND:Biliary stent restenosis is one of the main long-term complications following biliary stent restenosis implantation,which affects its application.OBJECTIVE:To evaluate the reasons for the biliary stent restenosis and to explore corresponding prevention methods.METHODS:A computer-based online search of MEDLINE,Cochrane library,CNKI and VIP between January 1989 and August 2009 was performed to search related articles with the key words of "biliary metal stent,reobstruction,and interventional therapy".Literatures related to biliary stent restenosis were selected,in the same field,the articles published lately or published by authoritative journals were preferred.A total of 171 articles were searched and 22 documents were included according to inclusion and exclusion criteria.RESULTS AND CONCLUSION:Tumor growth,gallstone formation and inflammatory hyperplasia are the main reasons for restenosis following biliary metal stent implantation.The interventional therapy is an effective way for the patients of stent restenosis.Simultaneously,the therapeutic efficacy and living quality of patients can be improved by noticing preoperative conditions,in-time detecting and controlling biliary infection,reducing complications as well as strengthening postoperative combined therapy.
