Identifying factors that predict failure in treating complex bile duct stones

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to enhance the management of complex bile duct stones by identifying predictive factors that may lead to failure during cholangioscopy-assisted lithotripsy using the SpyGlass system. It will analyze data from adult patients who underwent this procedure between January 1, 2018, and May 30, 2025, to determine which factors are associated with unsuccessful outcomes. The study will focus on retrospective data collection to draw insights that could improve future treatment strategies.
