  • 1

    Malignant hilar biliary obstruction has a poor prognosis, with a 5-year survival rate of less than 10%.

  • 2

    Endoscopic drainage using stent placement is the preferred palliative approach for managing malignant hilar biliary obstruction.

  • 3

    Plastic stents and uncovered self-expanding metallic stents are commonly used for endoscopic drainage, but their effectiveness varies.

  • 4

    SEMS generally show lower dysfunction rates and longer patency compared to plastic stents, though survival benefits remain debated.

  • 5

    Reintervention may be necessary for recurrent biliary obstruction, especially in patients undergoing systemic treatments.
