24-hour gastroesophageal double pH monitoring acid and alkaline gastroesophageal and duodenogastric refluxes in pediatric patients

摘要

Conclusions Transitory GER and DGR at meal times and 2 hour later might be a physiologic phe- nomenon. Acid and alkaline reflux occurring in the supine position during P2 should be considered of pathologic significance. This combined gastroe- sophageal pH monitoring is used not only to improve the diagnostic rate but also to guide clinicians to choose efficient anti-reflux therapy based on the type of reflux as well a to provide refined information for the further study of the pathophysiology of duodenogastro- esophageal reflux.
