비심인성 흉통에서 고해상식도내압검사의 역할 = The Role of High Resolution Manometry in Non-Cardiac Chest Pain

다국어 초록 (Multilingual Abstract)

The most common cause of noncardiogenic chest pain is gastroesophageal reflux disease, and other esophageal motility disorders are also frequent. Esophageal manometry is important for diagnosing esophageal motility disease. Recently, high resolution manometry (HRM) has emerged and is reported to be more useful than conventional esophageal manometry in evaluating primary esophageal motility disease. In this study, the role and usefulness of HRM in noncardiac chest pain were investigated. From August 2018 to April 2021, 136 patients with chest pain were enrolled. Classification was carried out according to Chicago classification version 3.0, and 95 out of 136 patients showed normal findings, and 23 patients showed ineffective esophageal motility. When gastroesophageal reflux disease was classified according to Los Angeles (LA) classification, LA-M was 20% (6/30), LA-A was 63.3% (19/30), LA-B was 16.6% (5/30), and LA-C was, there were no patients with LA-D. Through this study, it was confirmed that about 22% of patients with noncardiogenic chest pain had reflux esophagitis, and about 30% of patients had esophageal motility disease. High-resolution esophageal manometry appears to be useful for the differentiation of noncardiogenic chest pain caused by esophageal motility disorders other than reflux esophagitis. After diagnosis of esophageal motor disease, follow-up studies on whether non-cardiac chest pain improves after drug treatment is required.
