title: [Clinical significance of 24-hour intraesophageal pH monitoring in GERD patients].
abstract: 24-hour intraesophageal pH monitoring(24-pH-M) is a method of choice to measure the esophageal acid exposure, and evaluate a patient's lifestyle who has reflux symptoms. The 24-pH-M is indicated to the cases who have at least one of the following signs/symptoms; endoscopy negative GERD(gastroesophageal reflux disease), atypical clinical course for reflux disease, atypical symptoms of GERD, and those who are subjected to have surgical treatment. In the 24-pH-M, not only the duration of gastroesophageal reflux(GER), but also reflux and symptom association should be evaluated. The 24-pH-M is useful to investigate the diagnosis and treatment of GERD including reflux esophagitis.
