Definition and Pathophysiology of Boerhaave and Mallory-Weiss Syndrome
In the Boerhaave syndrome, a rupture of all layers of the esophagus occurs. In most cases, the lower half of the esophagus, dorsolaterally on the left side, is affected. A relatively low muscle tone is prevalent here, as in other areas of the esophageal muscles. The event of rupture is preceded by an acute pressure load, with strong, forced vomiting in most cases, typically in conjunction with excessive alcohol consumption.
The Mallory-Weiss syndrome is also preceded by forced vomiting and retching. The mucosa of the esophagus is here already damaged, often due to high alcohol consumption, less commonly due to chronic gastroesophageal reflux disease or atrophy (with elderly patients). Finally, in the course of acute pressure load, longitudinal lacerations of the mucosa and submucosa, particularly in the area of the gastroesophageal junction occur. The muscularis mucosae remains intact, so there is no perforation!
Epidemiology of Boerhaave and Mallory-Weiss Syndrome
Both symptoms affect men more often than women and are found especially in alcoholics.
The Mallory-Weiss syndrome makes up approximately 5 – 10 % of the causes of upper gastrointestinal bleeding.
Symptoms of Boerhaave and Mallory-Weiss Syndrome
Retrosternal pain and hematemesis
In the Boerhaave syndrome, patients describe something close to retrosternal destruction pain after vomiting. This sensation may radiate to the back.
Dysphagia and dyspnoea are common symptoms. A pneumothorax also often occurs with or without pleural effusion due to esophageal rupture and the nearby pleura. Another ground-breaking finding is the development of cutaneous emphysema. If it is above the jugular, it needs to be considered as an indication of mediastinal emphysema. The combination of severe vomiting, retrosternal destruction pain and cutaneous or mediastinal emphysema is also called Mackler’s triad.
In addition, the Mallory-Weiss syndrome is accompanied by severe pain, which, however, patients often locate in epigastric areas. The hematemesis is in this case decisive, particularly the vomiting of blood.
Boerhaave and Mallory-Weiss syndrome may have similar clinical manifestations and are thus differential diagnoses when the aforementioned symptoms are both pointed out. Furthermore, a rupture of esophageal varices must be considered alongside the corresponding anamnesis (alcoholics, liver cirrhosis?). The varices can rupture during heavy vomiting and cause hematemesis.
Diagnosis of Boerhaave and Mallory-Weiss Syndrome
Medical imaging and oesophagogastroscopy
In the Boerhaave syndrome a radiograph of the chest and esophagus with water-soluble contrast medium (No Barium in case of suspected perforation! Risk of mediastinitis!) should be performed immediately.
In this instance, first indications of the syndrome arise when the following questions are asked: How is the contour of the esophagus shaped? Is there a pneumothorax or a pleural effusion?
In CT thorax, more accurate statements about the extent of the rupture can be made; also, cutaneous emphysema can be seen here distinctly.
If the Mallory-Weiss syndrome is suspected, an oesophagogastroscopy should be performed immediately, as this can also be connected to similar therapeutic intervention.
Therapy of Boerhaave and Mallory-Weiss Syndrome
Surgery, stent or fibrin?
If the Boerhaave syndrome is diagnosed, a surgery should be performed within the first 24 hours (mortality usually up to 60 %). Here, the ruptured portions are released and sutured. If this is not possible due to pronounced results, an oesophagectomy with gastric pull-up or colon interponation must be performed. If the rupture only has a small extent, an endoscopical stent can be attempted. Due to the risk of mediastinitis broad-spectrum antibiotics must be introduced!
In the Mallory-Weiss syndrome, however, surgery is rarely necessary. Here usually an endoscopic haemostasis (fibrin glue or injection of adrenaline in the source of bleeding) is sufficient.
Mediastinitis and blood loss
As part of the esophageal perforation in the Boerhaave syndrome mediastinitis can develop. Typical symptoms include fever, restrosternal pain, cutaneous emphysema, superior leverage accumulation and shock. The upper respiratory tract may be moved. A sepsis with spread to the pleura or pericardium is possible.
Another dangerous consequence is a thrombosis of the vena cava. If a chest x-ray exhibits a widened mediastinum and cutaneous emphysema in the area of the jugular, these are considered warning signs for mediastinitis.
In the Mallory-Weiss syndrome, lesions of the mucous membrane and consequent bleeding are crucial. Especially in patients treated with anticoagulant drugs, it can lead to high blood loss.

3. A 40-year- old man is brought to the emergency department by ambulance. He had suddenly felt after an episode of severe vomiting stabbing pains on the left thoracic side. Since then, he complains of increasing dyspnoea. The patient shows cold welding and is tachycardic. In his anamnesis alcohol abuse is found. In his chest X-ray, you notice a widened mediastinum and cutaneous emphysema on the jugular. What diagnosis is most likely?
- Esophageal variceal rupture
