Ultrasound may offer quick, painless constipation diagnosis for children
NCT ID NCT07656896
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.
