Prospective Evaluation of the Clinical Utility of Endoscopically-placed Self Expandable Stents
The current standard of care for bile duct stone are endoscopic sphincterotomy and stone
extraction. Placement of plastic stents is an option for incomplete biliary stone
clearance. This study will use the CSEMS in patients with complex biliary stones who failed
stone extraction as they have the advantage of large stent diameter. CSEMS may offer a
temporizing measure that allows more successful subsequent stone clearance. However, their
use in benign condition has been limited especially for biliary stone removal. The purpose
of this study is to determine the feasibility, safety, easy removability, stent-stone
formation rate, and migration rate of CSEMS for complex biliary stones.
