Summary

This trial tests whether doing a second ultrasound of the gallbladder, a few hours after the first, helps emergency doctors identify inflammation that the initial scan missed. Adults with abdominal pain and an unclear first ultrasound will get a repeat scan while still in the emergency department. Researchers will track their final diagnoses and outcomes to see if the extra scan improves early detection of acute cholecystitis.

What this could mean

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

Active substance
Repeat biliary point of care ultrasound
What this could lead to
If it works, a second ultrasound could help emergency doctors spot gallbladder inflammation earlier, reducing missed cases and speeding up treatment.
What could go wrong
This is a small, early study, and the repeat scan may not change outcomes for many patients. The test's accuracy could also vary depending on the person performing it.
