Clinical Trial Summary

Multi-center, randomized controlled study fc-SEMS with anchoring plastic stent vs uc-SEMS in malignant biliary obstruction

Description:

This study is multi-center, randomized controlled study to compare the stent patency in malignant biliary obstruction. The patency of fully covered self expandable metal stent with external anchoring plastic stent was compared with that of uncovered self expandable metal stent.
