Acid and bolus exposure in pediatric reflux disease according to the presence and severity of esophageal mucosal lesions

Purpose The relationship between reflux index (RI) and bolus exposure parameters in multichannel intraluminal impedance (MII) has not been examined sufficiently among children. The significance of acid and bolus exposure in evaluating pediatric reflux disease (RD) was explored by focusing on mucosal lesions.
