As more studies of stents are done, stents need to be developed with the capacity to avoid bacterial or tumor colonization or which have anti-bacterial and/or chemo-radio therapeutic elements. The stents of the future should have longer patency, less need of reinterventions, better cost-benefit relationships and longer patient survival. The authors of this study declare their absolute independence from stent producers and producers of drugs used in patient management.
No está claro si el recambio de stents deba hacerse en una forma programada o bien esperar el momento de la oclusión, aunque algunos sugieren que cursan con un mejor pronóstico los pacientes con recambios programados 19, otros indican hacerlo al momento de la disfunción porque con esta política rara vez se produce colangitis 20, 29.
