title: [Gastroesophageal reflux disease].
abstract: Physiological gastroesophageal reflux (GER) is the passage of gastric contents into the esophagus and occurs up 2/3 of normal infants; and, it resolves spontaneously around 9-12 months of age. When GER causes symptoms or complications is considered gastroesophageal reflux disease (GERD) and it is associated to growth impairment, anemia, apnea, wheezing or other chronic respiratory symptoms, asthma, recurrent pneumonia or sleeping problems. Diagnosis of GERD implies studies as upper gastrointestinal series, upper endoscopy and 24 h esophageal pH monitoring; special cases may require motility and nuclear medicine studies. GER may be successfully treated with prone elevated position (30-45 degrees), shortening the feeding intervals to 3 h and anti-GER high-viscosity formulas. The regular use of prokinetic drugs is not recommended. The efficacy of proton pump inhibitors and H2 histamine receptor antagonists in the treatment of GERD has been demonstrated in children by diminishing de acid secretion of parietal cells, lowering the gastric contents and decreasing its ability to cause peptic-acid damage to the esophagus or to the respiratory tract. Surgical treatment is indicated in chronic recurrent GERD, usually in children 5 years or older with dependent proton pump inhibitor erosive esophagitis, chronic respiratory disease and in risk-selected cases.
