Application of Fully Covered Self-Expandable Metallic Stents with and without Antimigration Waist Versus Repeated Plastic Biliary Stent Placement in Management of Anastomotic Biliary Strictures After Orthotopic Liver Transplantation

摘要

BakgroundStandard methods for endoscopic retrograde cholangiopancreatography (ERCP) management of anastomotic strictures (AS) after OLT includes repeated balloon dilation of the stricture with subsequent insertion of a plastic biliary stent (PBS). In post-OLT patients not responding to standard endoscopic treatment, the placement of fully covered self-expanding metal stents (FCSEMS) is a valid alternative to surgical treatment. The aim of this study was to compare the results of new FCSEMS implantation with the standard ERCP stricture management protocol and with conventional FCSEMS insertion.
