摘要

It is now over 20 years since the introduction of multichannel intraluminal impedance monitoring (MII) in the oesophagus. Soon following, its application in children began in earnest with the widespread availability of paediatric catheters in 2002. MII detects oesopha-geal bolus movement by measurement of changes in electrical resistance and is used for assessment of reflux in tandem with pH monitoring (MII-pH). MII-pH heralded an advance in our ability to characterise reflux compared with the previous gold standard, pH monitoring alone. Advantages include the ability to detect nonacid and weakly acid reflux, distinguish between antegrade and retrograde bolus movements, differentiate liquid from gas reflux and assess proximal extent of the refluxate. In the intervening period, the translation of this more sophisticated and accurate measurement into improved patient outcomes has, however, not been as demonstrable as would have been hoped for.
