Esophageal pH impedance monitoring in children: SIGENP position paper

Esophageal pH impedance is the most accurate diagnostic procedure for gastro esophageal reflux diagnosis. In the last ten years, due to many clinical studies, its use in the world has been gradually, implemented especially in newborns and in children. However, still some factors like the small size of the reference values in children and poor therapeutic options limit its current clinical impact. Through a revision of recent scientific evidences,this document was produced by the Neurogastroenterology and disease-acid-related working group of the Italian Society of Gastroenterology, Hepatology and Pediatric Nutrition (SIGENP) in order to standardize clinical indications, methodology, data analysis and pH reporting – esophageal impedance measurement in children and provide a practical reference for the diagnostic approach to children with symptoms of gastro-esophageal reflux
