b. If the MPD is disconnected, all but one plastic stent is removed. A single double pigtail plastic stent will be left in place indefinitely. In patients with FCSEMS and DPDS, the metal stent is removed and a single 7Fr double pigtail plastic stent is placed instead and left in place indefinitely. FCSEMS is replaced with double pigtail plastic stents in this group as thus far the long-term sequelae of inserted AXIOS stents are not known, including the risk of stent migration.
