Quagmire vessels are available, biliary endoprosthesis.

AB - A nonoperative method of palliation was used in four patients with malignant obstructive jaundice in whom biliary endoprosthesis could not be placed endoscopically. A guide wire was manipulated through the lesion by a percutaneous transhepatic route and retrieved from the duodenum through an endoscope. A 10 Fr stent was then passed through the endoscope over the guide wire across the stricture. The procedure was successful in all four patients, with no complication.

N2 - Our preliminary experience with a silicone internal biliary endoprosthesis with a proximal Malecot design and a wide distal tip has been encouraging. The endoprosthesis has had an acceptable patency rate, and complications associated with its placement have been relatively infrequent, probably because of the ability to place the stent with its tip in the distal common duct rather than in the duodenum.

What is the recommendation for sepsis following biliary stenting

Sludge formation was also significantly associated with an increasing indwelling time and the presence of sideholes. In line with our data, a previous study also reported a higher amount of sludge in polyethylene stents with sideholes in comparison to polyethylene stents without sideholes . An experimental study of biliary endoprosthesis efficiency showed that the presence of multiple sideholes does not increase the efficiency of the endoprosthesis, but impairs its mechanical properties . The authors argued by referring to the law of mechanics of virtue: By increasing the number of sideholes a luminal fluid stream passing through the tube is switched to a micro-disturbed fluid stream resulting in an increased resistance of the stent to the bile flow. In theory, sideholes should guarantee the biliary drainage in case of the proximal and distal main orifice being occluded by plugs or blocked by the wall of the bile duct . However, clinical significance of this hypothesis is still missing , . Sung et al. compared the clinical efficacy of stents with and without sideholes in a prospectively randomised control trial. In both stents with and without sideholes, the median time before stent occlusion was similar (7.8 vs. 7.9 weeks). Several studies showed that antimicrobial coatings on medical devices are effective against microbial biofilm formation. According to Agostinho et al. antimicrobially coated materials are able to significantly inhibit bacterial biofilm formation through microorganisms like Staphylococcus spp. over a certain time. A recent study reported similar findings, analyzing novel high efficiency coatings on anti-microbial surgical sutures using chlorhexidine in fatty acid slow-release carrier systems. Furthermore, the use of new coatings like diamond like carbons (DLC) seems to be a promising approach to reduce biofilm formation on medical devices. Due to its low friction coefficient, high biocompability, chemical inertness, and both high hardness as well excellent smoothness –, diamond like carbon is virtually predestined for use as a coating for biliary stents. Laube et al. investigated the ability of diamond-like carbon to decrease formation of crystalline bacterial biofilm as well as stent related side effects and reported an excellent handling, a less painful replacement procedure and high tolerance of application. Furthermore, no crystalline biofilm formation could be detected on the stent surface in vivo and the number and severity of symptomatic urinary tract infections was decreased.

The GORE VIABIL Biliary Endoprothethis offers an alternative for treating biliary malignancy. It can be placed percutaneously or endoscopically in the biliary tract, and features a nonporous ePTFE/FEP liner. The endoprothethis's flexible nitinol stent is claimed to have a higher radial or 'hoop' strength at body temperature than typical metallic binary stents.
