Stents antirrefluxo biliar estão sendo desenvolvidos, com as pesquisas em andamento. Esses stents podem reduzir potencialmente o risco de colangite a partir de contaminação bacteriana da árvore biliar e podem estar comercialmente disponíveis no futuro.[52]Hu B, Wang TT, Wu J, et al. Antireflux stents to reduce the risk of cholangitis in patients with malignant biliary strictures: a randomized trial. Endoscopy. 2014 Feb;46(2):120-6.
