      abstract     = {Endoscopic bilateral drainage for inoperable malignant
                      hilar biliary strictures (HBS) using metal stents is
                      considered to be technically difficult. Furthermore,
                      endoscopic revision of bilateral stenting after occlusion
                      can be challenging. This study was performed to evaluate the
                      long-term efficacy of endoscopic bilateral stent-in-stent
                      placement of cross-wired metallic stents in high-grade
                      malignant HBS and planned endoscopic bilateral revision.A
                      total of 84 patients with inoperable high-grade malignant
                      HBS were enrolled from three academic tertiary referral
                      centers. Two cross-wired metal stents were inserted using a
                      bilateral stent-in-stent placement method. Bilateral
                      endoscopic revision was also performed during follow-up
                      using either identical metal stents or plastic stents. The
                      main outcome measurements were technical and functional
                      success, complications, stent patency, and endoscopic
                      revision efficacy.The technical and clinical success rates
                      of endoscopic bilateral stent-in-stent placement of
                      cross-wired metallic stents were $95.2\%$ (80/84) and
                      $92.9\%$ (78/84), respectively. Median patency (range) and
                      survival were 238 days (10-429) and 256 days (10-1130),
                      respectively. Obstruction of primary bilateral stents
                      occurred in $30.8\%$ (24/78) of patients with functionally
                      successful stent placement. The technical and clinical
                      success rates of planned bilateral endoscopic revision for
                      occluded stents were $83.3\%$ (20/24) and $79.2\%$ (19/24),
                      respectively. For revision, bilateral metallic stents were
                      placed in 11 patients $(55.0\%);$ the remaining patients
                      received plastic stents.Palliative endoscopic bilateral
                      stent-in-stent placement of cross-wired metallic stents was
                      effective in patients with inoperable HBS. Revision
                      endoscopic bilateral stenting may be feasible and successful
                      in cases where the primary deployed metal stents are
                      occluded.},
