Overview

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
