TY - CHAP M1 - Book, Section TI - Chapter 11. Esophageal pH and Impedance Monitoring A1 - Rosen, Rachel A1 - Chiou, Eric A1 - Nurko, Samuel A2 - Bishop, Warren P. PY - 2010 T2 - Pediatric Practice: Gastroenterology AB - Gastroesophageal reflux (GER), defined as the passage of gastric contents into the esophagus, occurs on a daily basis as a normal process in infants, children, and adults. Most episodes of physiologic reflux are transient, asymptomatic, and reach only the distal esophagus. Gastroesophageal reflux disease (GERD) is distinguished by reflux into the esophagus resulting in well-defined symptoms or medical problems (see Chapter 12). When children present with atypical complaints or extraesophageal symptoms, testing may be necessary to document the presence or absence of pathologic reflux, or the association between reflux events and specific symptoms.1 SN - PB - The McGraw-Hill Companies CY - New York, NY Y2 - 2024/03/28 UR - accesspediatrics.mhmedical.com/content.aspx?aid=55940418 ER -
