Diagnosis and Treatment of Motility Disorder of the Esophagus, Non-Cardiac Chest Pain
摘要
Non-cardiac chest pain (NCCP) is epidemiologically common among cases of chest pain, and most causes of NCCP originate from esophageal disorders within the spectrum of gastrointestinal diseases. Among these, functional esophageal disorders hold an important clinical position, with key symptoms including heartburn, chest pain, and dysphagia. These disorders involve overlapping conditions such as esophageal motility disordersEsophageal motility disorders, gastroesophageal reflux disease (GERD)Gastroesophageal reflux disease (GERD), and NCCP. For diagnosis, it is essential first to rule out structural diseases of the upper gastrointestinal tract and ischemic heart disease. Subsequently, diagnostic tests such as esophagography, esophageal manometry, and 24-hour esophageal impedance-pH monitoring24-hour esophageal impedance-pH monitoring are necessary. The mechanism of pain in NCCP is thought to involve a lowered pain threshold. Emotional stress, such as anxiety, and psychosocial factors also contribute to the condition, often leading to delays in diagnosis and treatment. Therefore, while appropriate pharmacological treatment tailored to each individual pathology is essential, a psychosomatic approach similar to that used in treating functional somatic syndromes and chronic pain is also recommended.
