Stent occlusion may occur as the result of bacterial adherence and biofilm formation. This occlusion may be prompted by the material or design of the stents. In this study, a bile perfusion model was used to compare the biofilm formation on various stent materials. The copolymer and the wire mesh stents demonstrated less biofilm formation than the traditional stent. The development of new polymers may prolong stent patency.
