Abstract
Five pediatric patients with stridor were evaluated to determine whether gastroesophageal reflux (GER) contributed to their stridor. Intraluminal esophageal acid perfusion (Bernstein test), pH probe, radiographic studies, laryngobronchoscopy, and esophageal histology were utilized. Thereafter, three of the five patients responded to therapy for GER; two did not. The Bernstein test proved to have greater diagnostic reliability than any other test employed, using response to antireflux therapy as the “gold standard” for diagnosing reflux‐provoked stridor.
