Impaired gastric motility and its relationship to reflux symptoms in patients with nonerosive gastroesophageal reflux disease

摘要

Background More than half of patients with refluxrelated symptoms have no endoscopic evidence of mucosal breaks. These patients are considered to have nonerosive gastroesophageal reflux disease (NERD). The pathogenesis of NERD may be multifactorial, but the role played by gastric motility in symptom generation in patients with NERD has not been examined. In this study, we elucidate gastric motility in patients with NERD and the efficacy of a prokinetic agent in the treatment of NERD.
