[Boerhaave syndrome: update on physiopathology, diagnosis and early management]

Boerhaave syndrome is a rare condition, usually associated with a delay in diagnosis. It is fatal in the absence of therapy. The nonspecific nature of the clinical signs contributes to the poor outcome. This syndrome should be suspected in patients with severe chest or abdominal pain, associated with a history of vomiting, clinical signs of pneumomediastinum (subcutaneous emphysema, pleural effusion) and rapid clinical deterioration. Prompt diagnosis and initial management by the primary care physician and the emergency department physician are key elements of a better outcome. This article will review the pathogenesis, clinical manifestations, diagnosis and treatment of Boerhaave syndrome in adults.
