Detection of Gastroesophageal Reflux in Children Using Combined Multichannel Intraluminal Impedance and pH Measurement: Data from the German Pediatric Impedance Group

From this large systematically standardized data collection of MII-pH measurements in children, we conclude that 45% of the patients with abnormal GER would not have been recognized by 24-hour pH measurement alone. Our findings confirm that MII-pH is superior to pH monitoring alone in detecting GER.
