Official Title: Newly Designed Fully Covered Metal Stent for the Benign Biliary Stricture: Prospective Randomized Study

Brief Summary: The purpose of this study is to determine the feasibility, easy removability, safety, and migration rate of flared end fully covered self-expanding metal stent (FCSEMS) and anchoring FCSEMS for benign biliary stricture.

Detailed Summary: Benign biliary strictures (BBS) are usually managed with plastic stents, whereas placement of uncovered metallic stents has been associated with failure related to mucosal hyperplasia. Fully covered self-expanding metal stent(FCSEMS) placement was reported as a useful method for BBS. However, stent migration was a frequent complication of CSEMS placement. Recently, flared end FCSEMS was developed to decrease stent migration, and anchoring CSEMS was newly developed.

Current Primary Outcome: Stent migration rate [ Time Frame: one year ]

Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Feasibility (Technical success rate and functional success rate) [ Time Frame: one year ]
  • Safety (Procedure related early complications occurred within one month and late complications occurred one month after the procedure) [ Time Frame: one year ]
  • Removability [ Time Frame: one year ]


Original Secondary Outcome:

  • Feasibility [ Time Frame: one year ]
  • Safety [ Time Frame: one year ]
  • Removability [ Time Frame: one year ]
