Study summary

Dumping syndrome (DS) is frequent in oesophageal atresia (29%). In causing hypoglycaemia, it can be dangerous for neonates. Mechanisms of DS are actually partialy understood. This is also an affection difficult to diagnose, because it only occurs after meals and can be inconstantly present. To date, their is only symptomatic treatment for DS. This study aims to understand its pathological mechanisms so as to better treat it and avoid its consequences. Oesophageal atresia patients enrolled in this study will benefit from a continuous glycemic monitoring, a continuous cardiac monitoring, and an a gastric emptying scintigraphy at the age of 3 months

What researchers measure

Primary outcomes

  1. Abnormal glycaemia associated with vagal hypertonia

    Composite criteria: association between abnormal glycaemia (high or low) and variations of cardiac frequency

    Time frame: At least once during the 48 hours monitoring

Secondary outcomes

  1. Abnormal glycaemia associated with abnormal gastric emptying

    Composite criteria: association between abnormal glycaemia (high or low) and abnormal gastric emptying study

    Time frame: At least once during the 48 hours monitoring

  2. Persistance of dumping syndrome

    measured by a gastric emptying scintigraphy

    Time frame: At the age of 6 months

  3. Tolerance of glucose monitoring

    Occurrence of side effects or technical issues during monitoring

    Time frame: At least once during the 48 hours monitoring

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 23, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
