Dumping syndrome is infrequently reported, but known to occur after Nissen fundoplication in children. However, it may be difficult both to diagnose and manage. Here we presented four infants who received Nissen fundoplication for severe gastroesophageal reflux disease, two of whom developed dumping syndrome whilst the other two did not. Continuous glucose monitoring (CGM) was very useful to clearly detect large glycemic fluctuation around each feeding. CGM was also helpful to prove the effect of treatment to avoid abnormal glucose levels. We believe that dumping syndrome in children may be underdiagnosed if clinicians rely solely on the recognition of symptoms or limited frequency of blood samplings. CGM might be the most sensitive diagnostic tool.
