Comparing two types of catheters for removing bile duct stones
Official title: Randomized Trial of the Removal Ability With Vortic Catch V Basket Catheter Versus Ordinary Basket Catheter for Bile Duct Stones
Run by Showa Inan General Hospital · NCT05363345 · Data updated 2026-11-12
This study tests whether a new type of catheter can remove larger bile duct stones better than the standard catheter for patients with these stones.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are patients with suspected or known common bile duct stones that are 10 mm or larger and who have undergone endoscopic papillary balloon dilation.
✕Probably not a fit
Patients experiencing septic shock, coagulopathy, or suspected malignancy may not benefit from this study.

What this trial studies
This clinical trial aims to compare the effectiveness of the Vortic Catch V basket catheter against a standard ordinary basket catheter in removing bile duct stones that are 10 mm or larger. Patients suspected of having or confirmed to have common bile duct stones will be randomly assigned to receive one of the two catheter types during the procedure. The study will evaluate the success rate of stone removal using these two different catheters, providing insights into which method may be more effective for patients.
Why it matters
Potential benefit: If successful, this study could lead to improved techniques for the removal of bile duct stones, enhancing patient outcomes and reducing complications.
How similar studies have gone: While there may be existing studies on catheter effectiveness, this specific comparison of the Vortic Catch V basket catheter versus ordinary basket catheter is novel.
