Technique for the safe placement of a biodegradable stent into the common bile duct of rabbits

Abstract Biodegradable common bile duct (CBD) stents are in high clinical demand. Animal experiments concerning the surgical placement of biliary stents made of new materials are being performed more frequently than ever before. However, these animal experiments only use large animals. In this study, a central venous catheterization set was used as a modified stent introducer system in rabbits. A biodegradable Mg-6Zn alloy CBD stent was passed through the duodenal papilla using this stent introducer system. Computed tomography (CT) scanning
