Effect of covered self-expanding metal stents compared with multiple plastic stents on benign biliary stricture

摘要

Background:Endoscopic placement of multiple plastic stents (MPS) has been the first-line treatment for benign biliary stricture (BBS). Covered self-expanding metal stents (cSEMS) have been used in treatment of BBS; however, the efficacy has not been verified. Therefore, we conducted this meta-analysis according to PRISMA guidelines.
