Overview
Pathophysiology
- Boerhaave syndrome is a spontaneous perforation of the esophagus due to a sudden rise in intraesophageal pressure combined with negative intrathoracic pressure (eg, severe straining, vomiting or seizures) as a result of neuromuscular incoordination resulting in a longitudinal esophageal perforation.
- Boerhaave syndrome is commonly associated with the consumption of excessive food and/or alcohol.
- Boerhaave syndrome usually occurs in patients with a normal underlying esophagus, some patients with Boerhaave syndrome has underlying medication-induced esophagitis, eosinophilic esophagitis, Barrett's or infectious ulcers.
- The most common anatomical location of the esophageal perforation in Boerhaave syndrome is at left posterolateral wall of the distal intrathoracic esophagus, 2-3 cm before the stomach. However, the esophageal perforation in Boerhaave syndrome can occur in the cervical or intra-abdominal esophagus.[1]
