NCT04337333

Brief Summary

Endoscopic placement of a self-expandable metal stent (SEMS) is the principle method for palliation of inoperable malignant distal biliary obstruction. However, none of bare, covered, and anti-reflux metal stent alone constantly demonstrated superiority over the others in the stent patency. To compensate for the limitations of each stent, a double stent system in which both covered and bare SEMSs are integrated into one stent system was introduced. In the current study, the investigators aimed to evaluate the efficacy and safety of this stent in patients with inoperable malignant distal biliary obstruction.

Outcome Measures

Primary Outcomes (1)

  • Cumulative patency of inner covered stent and Two-in-one stent

    From the date of stent insertion until the date of first documented stent dysfunction, assessed upto 12 months
