Ultrasound study seeks to define 'Normal' lymph nodes in children to improve abdominal pain diagnosis
NCT ID NCT07704814
First seen Jul 15, 2026 · Last updated Jul 17, 2026 · Updated 2 times
Summary
This study uses point-of-care ultrasound to measure the number and size of lymph nodes in the lower right abdomen of children aged 2 to 16 who do not have abdominal pain or infection. By establishing what is normal, researchers hope to make it easier to diagnose mesenteric adenitis—a common cause of abdominal pain—when children do have symptoms. The goal is to turn ultrasound from a tool of exclusion into one of active diagnosis.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors use ultrasound to quickly identify abnormal lymph nodes and diagnose mesenteric adenitis in children with abdominal pain.
- What could go wrong
- This is an observational study to establish normal ranges, not a treatment trial. The findings may not change current practice or improve diagnosis in all cases.
