Bacteria have the capability to deconjugate bilirubin; producing bilirubin ate salt that might lead to stent occlusion. To prevent any kind of bacterial adhesion, a double-layer plastic stent possessing no side holes and with an internal coating of perfluoroalkoxy material was developed. Different types of plastic stent models possess side holes at both their ends to continue drainage if the tip of the stent is clogged; however, these side holes might favor sludge creation. Here in case you add an anti-reflux valve or make use of diverse types of coatings on stent surface, they might be the ways to avoid stent occlusion.
