title: Ultrasound as a screening study for gastro-oesophageal reflux in children.
abstract: A comparison of the abilities of ultrasound and scintigraphy to detect gastro-oesophageal reflux was made in 110 children (mean age 24.5 months) who were divided into groups A (n = 49) and B (n = 61). The former had scintigraphy first followed by ultrasound within about 30 min. For group B scintigraphy was also performed first, but the delay before ultrasound ranged between 1 and 30 days. In most patients (91/110) concordant results were obtained by the two modalities. The 19/110 discordant results can be explained by several plausible mechanisms. It is concluded that ultrasound should be employed much more frequently as an initial investigation when pathological reflux is suspected in children.
