title: Acid and nonacid reflux monitoring.
abstract: Detection of acid and nonacid reflux using esophageal reflux monitoring, which includes conventional and wireless pH monitoring and pH impedance, can be a valuable diagnostic tool when used appropriately in the assessment of patients with gastroesophageal reflux disease. Reflux monitoring may be especially helpful if a management change is desired, such as when initial or empirical treatment is ineffective. However, each of these methods has its limitations, which need to be accounted for in their clinical use. Indications, test performance, interpretation, and clinical applications of esophageal reflux monitoring, as well as their limitations, are discussed in this review.
