Several techniques have been used to diagnose gastroesophageal reflux (GER) in children, but no single test is sufficiently accurate to completely investigate the problem. Gastroesophageal US has been described as a widely available, noninvasive and sensitive method. It provides morphological and functional information, but its role in the diagnosis of GER in children is still debated. In this paper we review diagnostic approaches to GER in children.We focus on current use of US in the management of children with suspected GER. Reports suggest thatUS allows exclusion of several non-GER causes of symptoms and that it provides morphological and functional data with high sensitivity and positive predictive value for the diagnosis of GER. Sonographic assessment of findings such as abdominal esophageal length, esophageal diameter, esophageal wall thickness and gastroesophageal angle provide important diagnostic indicators of reflux and related to the degree of GER. There is a need for standardization of the procedure and for defining diagnostic criteria. © Springer-Verlag 2012.
