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.

Condition Intervention
Choledocholithiasis Procedure: ERCP with metal stent

Study Type: Observational
Study Design: Observational Model: Case-Only

Official Title: Prospective Evaluation of the Clinical Utility of Endoscopically-placed Self Expandable Stents

Further study details as provided by University of Florida:

Primary Outcome Measures:
  • complete biliary stone clearance [ Time Frame: 12 months ]
    This is an observational study where the ERCP being done is part of the standard of care for choledocholithiasis. There are no study interventions

Secondary Outcome Measures:
  • other techniques used for stone clearance [ Time Frame: 12 months ]
    This will include the number of ERCP's needed to achive the complete biliary stone clearance, Use of mechanical Lithotripsy, use of cholangioscopy, procedure duration and any adverse events safety

Enrollment: 0
Study Start Date: November 2011
Study Completion Date: June 2013
Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Incomplete biliary stone extraction. Procedure: ERCP with metal stent
ERCP will be used so that a metal stent can be placed to facilitate the removal of the biliary stone
