Dumping syndrome: chi è costei?

We report a case of dumping syndrome (DS) following Nissen fundoplication for gastroesophageal reflux in a syndromic child. DS refers to the symptom complex that results from the rapid gastric emptying, with consequent hyperglycemia followed by a reactive severe hypoglycemia. We review the literature about pathogenetic mechanisms, diagnosis and treatment of DS. As it occurred in our case, the diagnosis of DS is often delayed, especially in children with mental retardation.
