  1. Purpose of the study

    -To compare stent patency and complication rate between endoscopic ultrasound (EUS) guided stent insertion and endoscopic retrograde cholangiopancreatography (ERCP) guided stent insertion for malignant biliary obstruction

  2. Subjects of the study

    -Patients who have biliary obstruction owing to malignant tumors

  3. Methods of the study

    • Prospective randomized controlled study
    • Patients were enrolled randomly in two groups, EUS guided stent insertion group or ERCP guided stent insertion group
    • Patients will get assigned procedure (EUS guided stent insertion or ERCP guided stent insertion)for decompression of malignant biliary obstruction
    • After the procedure, regular follow up, blood test,and imaging test will be done to check sufficient biliary decompression,stent patency and complications.
