      metallic stent for malignant hilar biliary obstruction.

AB  - OBJECTIVES: Bilateral self-expandable metallic stent (SEMS) placement for 
      unresectable malignant hilar biliary obstruction (UMHBO) is an effective option 
      for biliary drainage with long-term stent patency. Laser-cut and braided SEMS can 
      be used for bilateral SEMS placement. This study aimed to clarify any differences 
      in the clinical features and proper use of the laser-cut and braided SEMS 
      placement using the stent-in-stent method for UMHBO. METHODS: In this study, 78 
      patients who underwent bilateral stent-in-stent SEMS placement for UMHBO were 
      included. The patients were divided into the laser-cut (n = 33) and braided 
      groups (n = 45). Both groups were compared for technical and clinical success, 
      adverse events (AEs), time to recurrent biliary obstruction (TRBO), overall 
      survival, and endoscopic reintervention (ERI). RESULTS: There were no significant 
      differences in technical and clinical success rates (laser-cut vs. braided group, 
      97% vs. 95.6%, P = 1.0), AEs (21.2% vs. 15.6%. P = 0.56), median TRBO (242 days 
      vs. 140 days, P = 0.36), and median overall survival (654 days vs. 675 days, 
      P = 0.58). ERI was required in 15 patients in the laser-cut group and in 20 
      patients in the braided group. The technical and clinical success rates of ERI 
      (60% vs. 85%) were not significantly different (P = 0.13); however, the median 
      ERI procedure time was significantly longer in the laser-cut group (38 min) than 
      in the braided group (22 min; P = 0.02). CONCLUSION: No significant difference in 
      initial SEMS placement was noted between the laser-cut and braided groups; 
      however, the laser-cut group required a longer ERI procedure time than that 
      required by the braided group. The use of braided SEMS may be a convenient option 
      for ERI.
