Abstract

GER and GERD are frequent conditions in infants, children, and adolescents. Symptoms differ with age, although the main pathophysiologic mechanism, transient relaxations of the lower esophageal sphincter, is identical at all ages. Although infant regurgitation is likely to disappear with age, little is known about the natural evolution of pediatric GER and GERD. The majority of reflux episodes are weakly acid, but the majority of “esophageal” symptomatic reflux is likely to be acid related. Regarding “extraesophageal manifestations,” measurement of nonacid reflux may be more relevant. Symptoms of GER are not specific and not sensitive. There is no golden-standard diagnostic technique. Impedance in combination with pH-metry is likely to replace simple pH-metry in the future. Treatment of regurgitation and moderate reflux disease should focus on reassurance and dietary and possibly positional treatment. Medical therapeutic options usually involve inhibition of acid suppression, although not all reflux symptoms and disease are caused by acid reflux. Alginates or antacids are useful when immediate symptom relief is required. No currently available prokinetic drug is indicated in the treatment of childhood GERD. Laparoscopic fundoplication is the recommended surgical procedure in selected cases of particularly severe and chronic GERD.
