Is the 13C-acetate breath test a valid procedure to analyse gastric emptying in children?
Scintigraphy is regarded as the “gold standard” procedure in measuring gastric emptying (GE) rates. 13C-acetate breath test (ABT), which already has been validated in adults, is a noninvasive and nonradioactive alternative method. The aim of the current study was to validate ABT against technetium Tc 99m scintigraphy in children affected by delayed GE.
