Study Overview

Malignant Obstruction ZILVER Against Routine Therapy (MOZART I)

This study compares the 6 mm nitinol Zilver biliary endoprostheses and the 10 mm nitinol Zilver biliary endoprostheses to the 10 mm Wallstent in appropriate patients in need of palliative treatment of malignant obstructive jaundice.

This research is being done to determine if the new, FDA-cleared Zilver metal biliary stent is better than the conventional stents. The new Zilver stent may permit more accurate placement, may avoid some potential complications and last longer than the conventional stents. The study will also examine to find the best diameter of stent by comparing standard 10 mm stents to 6 mm Zilver stents.
