Metal versus plastic stents for anastomotic biliary strictures after liver transplantation: a randomized controlled trial

cSEMSs were comparable with MPSs regarding post-OLT biliary anastomotic stricture resolution. cSEMSs allowed fewer procedures and had a positive effect on cost. Duration of treatment with cSEMSs should be further investigated. Sphincterotomy should be considered for all patients. (Clinical trial registration number: NCT 01148199.)
