[Thoracic pain of oesophageal origin. Diagnostic management and treatment]

FROM AN ETIOLOGICAL POINT OF VIEW: Thoracic pain is a frequent symptom. Before confirming the oesophageal origin of the pain, a coronary disease must be excluded. Two principle causes are source of thoracic pain of oesophageal origin: gastro-oesophageal reflux disease and oesophageal motility abnormalities. THE DIAGNOSTIC APPROACH: This must include the questioning of the patient and the usual paraclinical examinations. To confirm the diagnosis, these examinations must establish a chronological relationship between the symptoms and the abnormalities. For economic reasons, following a normal gastroscopy, there is a tendency to propose an empirical proton pump inhibitor (PPI) test rather than a 24 hour pH-metry antireflux as first line. The improvement or even the disappearance of the symptoms confirms the diagnosis; long-term treatment with a double dose of PPI should therefore be envisaged. The pH-metry with search for results should be proposed to the non-responders and to patients with atypical reflux manifestations. Dysphagia and odynophagia suggest an oesophageal motility disorder that basal manometry should confirm. A chronological relationship is rarely revealed, but the sensitivity of the pH-meter can be enhanced by provocation tests. REGARDING TREATMENT: Other than achalasia, treatment of the other spastic-like motor disorders is not well codified. Diltiazem is efficient. Some patients exhibit a hyperalgic oesophagus. The physiopathological mechanisms are still theoretical. Low dose tricyclic antidepressors and psychological management are useful.
