Challenges in the diagnosis of Boerhaave syndrome: A case report

RATIONALE: Acute chest pain remains one of the most challenging complaints of patients presenting to emergency departments (EDs). The diverse etiologies of chest pain frequently lead to diagnostic and therapeutic challenges. Esophageal perforation is a rare but potentially life-threatening disease. It results in delayed diagnosis and an estimated mortality risk of 20% to 40%. Prompt diagnosis and immediate therapeutic interventions are key factors for a good prognosis. PATIENT CONCERNS: Case 1 involved a 66-year-old man who presented to the ED with acute chest pain radiating to the back and hematemesis. Emergent contrast thoracic computerized tomography (CT) indicated the presence of a massive pneumothorax with pleural effusion. The continuous drainage of a dark-red bloody fluid following emergent thoracic intubation led to the discovery that the patient had experienced severe vomiting after whiskey consumption before admission to the hospital. Re-evaluation of the CT indicated spontaneous pneumomediastinum, whereas barium esophagography confirmed the presence of an esophageal perforation. Case 2 involved an 18-year-old Vietnamese man admitted to our ED with acute chest pain and swelling of the neck after vomiting due to beer consumption. A chest x-ray indicated diffuse subcutaneous emphysema of the neck and upper thorax. Contrast CT indicated pneumomediastinum with extensive emphysema and air in the paraspinal region and spinal canal. DIAGNOSES: Both of the 2 cases were diagnosed as spontaneous perforation of the esophagus (Boerhaave syndrome [BS]). INTERVENTIONS: Case 1 received surgical interventions, whereas case 2 decided not to avail our medical services. OUTCOMES: Case 1 was discharged after a good recovery. Case 2 lost to follow-up. LESSONS: We recommend all physicians in the ED to raise their index of suspicion for BS when dealing with patients having acute chest pain, dyspnea, confirmed pneumothorax, or newly-developed pleural effusion.
