Quick Answer
Boerhaave syndrome is a spontaneous rupture of the entire esophageal wall caused by extreme straining, usually from forceful or repeated vomiting [1]. It is rare and causes sudden severe chest pain, vomiting, painful swallowing, fever and a rigid abdomen. Speed matters: treatment within 24 hours brings a 75% survival rate [2], while after 48 hours the death rate reaches 90%.
What the research says
In a recent 13-year hospital series, late diagnosis was linked to higher mortality. Among 21 patients with Boerhaave syndrome, 13 (62%) were diagnosed within 24 hours and 8 (38%) later. Overall 90-day mortality was 14%, but it was 38% (3 of 8) in the late-diagnosed group versus 0% (0 of 13) in the early-diagnosed group (p = 0.042), and all three patients who died had either refused treatment or were unfit for it (Kooij et al., Surg Endosc, 2025) [6].
Early treatment led to better survival across esophageal perforations. In a review of 62 patients treated for esophageal perforation (including 6 with Boerhaave syndrome), overall hospital mortality was 14.5%, early treatment led to better survival than treatment delayed beyond 24 hours, and both surgical repair and conservative or endoscopic treatment were used successfully (Schmidt et al., Surg Endosc, 2010) [7].
Older reports describe much higher death rates when treatment is late. A literature review notes that Boerhaave syndrome most commonly affects males between 50 and 70 years of age, that mortality reaches 40% to 60% in those treated at 48 hours, and that the outlook improves if treatment starts within the first 24 hours (Salvador-Ibarra and Pizaña-Davila, Cir Cir, 2021) [8].
What Is Boerhaave Syndrome?
Boerhaave syndrome is a rupture of your esophagus caused by tremendous stress. It happens when forceful vomiting or excessive straining cause the wall of the esophagus — the tube that carries food from your mouth to your stomach — to split open [1]. Healthcare professionals call this an "effort rupture" or "spontaneous rupture" to distinguish it from ruptures caused by direct injury to the esophagus.
It is a rare condition, affecting an estimated 0.0003% of the population [4]. It represents 15% of all traumatic ruptures of the esophagus [2]. And it is an emergency: when the esophagus tears, toxic contents can leak out and cause infection. Without treatment, Boerhaave syndrome can be fatal within days.
How is it different from a Mallory-Weiss tear?
A Mallory-Weiss tear is a tear in the inner lining of the esophagus. Like Boerhaave syndrome, it also occurs after forceful vomiting or straining, and both are associated with heavy alcohol drinking. A Mallory-Weiss tear causes vomiting blood, but it does not tear all the way through the esophagus [1]. Boerhaave syndrome, on the other hand, ruptures the full thickness of the esophagus wall — known as a transmural tear. A transmural tear will likely need emergency repair, and repairing it can be a matter of life or death.
Why is the rupture so dangerous?
Your esophagus is part of your digestive tract, and it is designed to carry substances that are toxic to the rest of your body. If food particles, bacteria, and digestive chemicals leak from the esophagus into your chest or abdomen, serious infection can result. Infection that enters your bloodstream can lead to septicemia and sepsis — a life-threatening reaction that can include shock, multiple organ failure, and death [4].
Who does Boerhaave syndrome affect?
It can affect anyone, but it is more frequent in men and in people older than 50. Up to 80% of those affected are middle-aged males. It is more common in people who drink heavily [1].
What Are the Symptoms?
The hallmark symptom is sudden, severe chest pain [1]. Other signs include nausea and vomiting, pain or coughing when swallowing, short and rapid breathing, swelling in the tissues of the chest cavity with air or fluid, a hard and rigid abdomen, and signs of infection such as fever and sweating.
The pain is described as severe — some say excruciating — and is vaguely localized around the site of the rupture. The rupture most often occurs in the lower third of the esophagus [2], where it passes through the bottom of the chest cavity and the top of the abdominal cavity, though it could be higher. The pain may also radiate to your back or shoulder.
Possible complications | What happens |
Chest cavity inflammation | Inflammation and swelling in the chest cavity |
Empyema | A build-up of pus in the chest cavity |
Trapped air | Air trapped in the chest cavity or in the tissues under the skin (subcutaneous emphysema) |
Pleural effusion | A build-up of fluid in the lining of the chest cavity |
ARDS | Acute respiratory distress syndrome |
Septicemia, sepsis, and shock | Infection that spreads to the bloodstream and becomes life-threatening |
Emergency — call 911: Sudden, excruciating chest pain after forceful or repeated vomiting — especially with fever, rapid breathing, or a rigid abdomen — can signal a ruptured esophagus. This is a life-threatening emergency. Do not wait for symptoms to improve. Get emergency care immediately.
What Causes Boerhaave Syndrome?
Two factors seem to be involved. The first is a build-up of pressure inside the esophagus from extraordinary effort or straining. The second is a build-up of negative pressure outside the esophagus when the upper esophageal sphincter (the cricopharyngeus muscle) fails to relax in response to pressure [1] [2]. Normally, nerve signals would trigger this muscle to relax and release the internal pressure — but in Boerhaave syndrome, this neuromuscular coordination fails for some reason.
The most common cause of the strain is forceful or repeated vomiting [1]. Other possible causes include childbirth, seizures, weightlifting, and swallowing something caustic or corrosive.
Does alcohol play a role?
Excessive alcohol use is certainly a risk factor. The classic presentation follows repeated vomiting after excessive food and/or alcohol consumption. Alcohol use disorder sets the stage, as do binge eating and bulimia [1].
Other possible risk factors include underlying esophageal disorders such as esophagitis, eosinophilic esophagitis, Barrett's esophagus, and peptic ulcer disease. However, most people affected by Boerhaave syndrome have a normal esophagus [1].
How Is Boerhaave Syndrome Diagnosed?
Boerhaave syndrome can be difficult to diagnose, and timely diagnosis is important. It is easier when the patient presents with the classic symptom pattern known as the Mackler triad: severe or repeated vomiting, sudden chest pain, and subcutaneous emphysema — air trapped in the tissues under the skin [1] [2]. That last symptom is especially telling of an esophageal rupture.
Not all cases present classically. The rupture may occur in an uncommon location, causing pain in an unusual area like the neck or collarbones. It may come from less common causes than vomiting, or produce uncommon side effects. A standard chest X-ray might give some hints, but a more sensitive imaging test is needed to confirm the diagnosis.
Imaging test | How it works |
Esophagram (first choice) | A fluoroscopic X-ray with water-soluble contrast dye that you swallow; quick, noninvasive, and highly accurate; shows exactly where dye leaks out through a tear |
CT scan | An alternative if the esophagram cannot be done or if the provider needs detail of surrounding organs; finds small amounts of leaked dye and air, and locates fluid pockets in the chest and abdomen that need draining |
How Is Boerhaave Syndrome Treated?
Treatment happens in coordinated steps, and time is critical.
Treatment step | What happens |
IV fluids | Most people need immediate IV fluid resuscitation due to overall volume loss |
Antibiotics | Broad-spectrum IV antibiotics to control infection |
Surgical consult | Surgery is the standard of care; small, contained ruptures may qualify for observation with IV antibiotics or endoscopy instead, but providers keep a surgical backup plan |
Surgical repair | Ideally the rupture is repaired directly within 24 hours, sometimes with minimally invasive VATS; some emergency cases need an open thoracotomy |
Drainage / debridement | Infected fluid collections are drained and sterilized; infected or dead tissue is removed; severe cases may mean removing part of the esophagus |
Advanced management | If surgery cannot happen within 24 hours, wound edges stiffen or fray and part or all of the esophagus may need removal (esophagectomy); a replacement is possible after six weeks |
Alternative nutrition | While the esophagus heals, food comes by tube or by vein |
What Is the Outlook?
Early diagnosis and treatment are the keys to avoiding infection complications, including death. Those treated within 24 hours have a good prognosis, with a survival rate of 75% [2]. After 24 hours, the chance of death is more than 50%, and after 48 hours it reaches 90%. The overall mortality rate is around 35%. People who are successfully treated in time can heal completely, though recovery may take several months.
Can Boerhaave Syndrome Be Prevented?
Because the classic presentation follows repeated vomiting after excessive food and alcohol consumption, avoiding heavy binge drinking is one clear, avoidable risk factor. People with conditions that cause repeated vomiting — such as alcohol use disorder, binge eating disorder, or bulimia — face higher odds and should seek care for those conditions. There is no guaranteed way to prevent this rare event, which can strike suddenly and without warning even in people with a normal esophagus.
Conclusion
Boerhaave syndrome is a rare but sobering emergency: an esophageal rupture triggered by the body's own straining, most often after forceful vomiting. Its danger lies in what leaks — food particles, bacteria, and digestive chemicals that can spark sepsis. The clock is the enemy: treatment within 24 hours offers a 75% survival rate [2], but the outlook drops sharply with every hour lost. If sudden, severe chest pain strikes during or after intense vomiting, treat it as an emergency and get help immediately.

Frequently Asked Questions
What is Boerhaave syndrome?
It is a spontaneous rupture of the entire wall of the esophagus caused by tremendous straining, most typically during forceful or repeated vomiting. It is a medical emergency that can be fatal without treatment.
How rare is Boerhaave syndrome?
Very rare — it affects an estimated 0.0003% of the population and represents 15% of all traumatic ruptures of the esophagus.
What does Boerhaave syndrome feel like?
The pain is severe — some describe it as excruciating — centered vaguely around the rupture, most often the lower third of the esophagus. It may radiate to the back or shoulder and comes with nausea, rapid breathing, fever, and a rigid abdomen.
What is the Mackler triad?
The classic set of three symptoms — severe or repeated vomiting, sudden onset chest pain, and subcutaneous emphysema (air trapped in the tissues under the skin). The air under the skin is especially telling of an esophageal rupture.
How is Boerhaave syndrome different from a Mallory-Weiss tear?
A Mallory-Weiss tear only damages the inner lining and causes vomiting of blood. Boerhaave syndrome is a full-thickness (transmural) tear that ruptures the entire esophagus wall and usually requires emergency surgery.
Why is a ruptured esophagus so dangerous?
The esophagus carries substances toxic to the rest of the body. When they leak into the chest or abdomen, serious infection can develop and spread to the bloodstream, causing septicemia, sepsis, shock, multiple organ failure, and death.
Who is most at risk?
Up to 80% of those affected are middle-aged males, especially heavy drinkers. It is more frequent in men and in people older than 50.
What causes the esophagus to tear?
Two pressure factors combine — extreme pressure building inside the esophagus from straining or vomiting, and negative pressure outside the esophagus when the upper esophageal sphincter fails to relax as it should.
Can heavy alcohol use cause a ruptured esophagus?
Excessive alcohol use is a major risk factor. The classic presentation follows repeated vomiting after excessive food and alcohol consumption. Alcohol use disorder, binge eating, and bulimia all set the stage.
Besides vomiting, what else can trigger it?
Childbirth, seizures, weightlifting, and swallowing something caustic or corrosive can also cause the strain that ruptures the esophagus.
How is Boerhaave syndrome diagnosed?
Through imaging — usually an esophagram (a fluoroscopic X-ray with swallowable contrast dye that shows where the dye leaks) or a CT scan, which finds leaked dye, air, and fluid pockets in the chest and abdomen.
How is it treated?
Immediate IV fluids and broad-spectrum IV antibiotics, followed by surgical consultation. Surgery — ideally direct repair within 24 hours, sometimes minimally invasive — is the standard of care, along with draining infected fluid and removing dead tissue. While healing, nutrition comes by tube or vein.
What happens if surgery is delayed?
After 24 hours, the wound edges stiffen or fray and direct repair may no longer work. The surgeon may need to remove part or all of the esophagus (esophagectomy), with a replacement possible after six weeks.
What is the survival rate?
Those treated within 24 hours have a 75% survival rate. After 24 hours, the chance of death exceeds 50%; after 48 hours it reaches 90%. The overall mortality rate is around 35%.
Can you fully recover from Boerhaave syndrome?
Yes — those successfully treated in time can heal completely, although recovery may take several months.
