Gastroesophageal reflux in children: an updated review

BACKGROUND: Gastroesophageal reflux is a common disorder in pediatrics. Clinicians should be familiar with the proper evaluation and management of this condition. OBJECTIVE: To provide an update on the current understanding, evaluation, and management of gastroesophageal reflux in children. METHODS: A PubMed search was performed with Clinical Queries using the key term 'gastroesophageal reflux'. The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews. The search was restricted to the English literature and the pediatric age group. RESULTS: Regurgitation is the most frequent symptom of gastroesophageal reflux and is present in nearly all cases. Gastroesophageal reflux occurs normally in infants, is often physiological, peaks at 4 months of age, and tends to resolve with time. Gastroesophageal reflux disease occurs when gastric contents reflux into the esophagus or oropharynx and produce troublesome symptom(s) and/or complication(s). A thorough clinical history and a thorough physical examination are usually adequate for diagnosis. When the diagnosis is ambiguous, diagnostic studies may be warranted. A combined esophageal pH monitoring and multichannel intraluminal esophageal electrical impedance device is the gold standard for the diagnosis of gastroesophageal reflux disease if the diagnosis is in doubt. In the majority of cases, no treatment is necessary for gastroesophageal reflux apart from reassurance of the benign nature of the condition. Treatment options for gastroesophageal reflux disease are discussed. Antireflux surgery is indicated for patients with significant gastroesophageal reflux disease who are resistant to medical therapy.
