Preliminary Study of Pediatric Diaphragmatic Elastography

Ultrasound Functional Analysis of the Diaphragm and Upper Digestive Tract in Patients with Congenital Diaphragmatic Hernia

This diaphragmatic elastography study is a preliminary pilot study to have first values of diaphragmatic stiffness in patients with a history of diaphragmatic hernia and to estimate the difference in stiffness compared to a group of patients without a history of hernia.

The hypothesis is to be able to correlate the values found with the patients' symptomatology and thus to better monitor patients by a simple, accessible, painless and reproducible diagnostic tool, to better understand their evolution and even to be able to anticipate possible difficulties (reflux, respiratory disorders, scoliosis, etc.).

Ultrasound elastography is a recent and clinically recognized method that uses an ultrasound approach to determine tissue stiffness in a non-invasive way.
