Summary

This study compared two devices used during a procedure called ERCP to remove stones from the pancreatic duct in people with chronic pancreatitis. One group used a basket first, the other a balloon first. The goal was to see which tool cleared more stones. A total of 104 adults with small stones (≤5 mm) in the main pancreatic duct took part.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Basket and balloon devices used during ERCP
What this could lead to
If successful, this could help doctors choose the best tool for removing pancreatic stones, potentially improving stone clearance and reducing procedure time.
What could go wrong
This is a small, completed study with only 104 participants. Results may not apply to all patients, and the tools may not work for larger or differently located stones.
