Summary

This study looks at whether measuring the rectal diameter with an ultrasound can accurately diagnose constipation in children aged 5-17. Researchers will compare ultrasound results with standard clinical criteria (Rome IV) in 130 children. If proven reliable, this simple, non-invasive test could help doctors diagnose constipation faster and more comfortably.

What this could mean

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

Active substance: Ultrasonographic rectal diameter measurement
What this could lead to: If successful, this could provide a non-invasive, radiation-free way to diagnose constipation in children, reducing the need for more uncomfortable tests.
What could go wrong: This is a relatively small, single-center study. The ultrasound measurement may not be accurate enough to replace current diagnostic methods, and results may not apply to all children.
