Overview

Definition: Boerhaave syndrome is a spontaneous, transmural esophageal rupture, typically occurring after forceful vomiting or retching, leading to mediastinitis and sepsis.
Epidemiology:
-Rare condition, incidence estimated at 1 in 10,000 hospital admissions
-More common in males, typically between 50-70 years old
-Often associated with alcohol abuse or binge eating.
Clinical Significance:
-A surgical emergency with high mortality if not promptly diagnosed and treated
-Understanding operative management is crucial for surgical residents preparing for DNB and NEET SS exams.

Clinical Presentation

Symptoms:
-Sudden onset severe retrosternal chest pain
-Vomiting or retching preceding pain
-Dyspnea and tachypnea
-Hematemesis or hemoptysis
-Subcutaneous emphysema in the neck or chest
-Fever and sepsis signs.
Signs:
-Tachycardia and hypotension
-Subcutaneous crepitus (Hamman's crunch)
-Mediastinal widening on chest X-ray
-Signs of shock and sepsis
-Diminished breath sounds.
Diagnostic Criteria:
-Mackler's triad (vomiting, chest pain, subcutaneous emphysema) is suggestive but not always present
-Definitive diagnosis relies on imaging and endoscopic confirmation of esophageal perforation.

Diagnostic Approach

History Taking:
-Detailed history of emesis, preceding events, chest pain character, duration, and associated symptoms
-Alcohol intake, prior esophageal pathology, and anticoagulant use are important.
Physical Examination:
-Assess for signs of hemodynamic instability
-Palpate for subcutaneous emphysema
-Auscultate for Hamman's crunch and diminished breath sounds
-Assess for abdominal tenderness.
Investigations:
-Chest X-ray: Mediastinal widening, pleural effusion, pneumomediastinum
-Contrast esophagography (Gastrografin or water-soluble contrast): Highly sensitive for detecting leak
-CT scan: Delineates extent of perforation, mediastinitis, and abscesses
-Esophagogastroduodenoscopy (EGD): Can confirm perforation but carries risk of worsening the tear
-usually performed after initial imaging.
Differential Diagnosis:
-Myocardial infarction
-Pulmonary embolism
-Aortic dissection
-Boerhaave syndrome
-Mallory-Weiss tear (mucosal tear, not transmural)
-Peptic ulcer perforation
-Acute pancreatitis.

Management

Initial Management:
-Immediate resuscitation: IV fluids, oxygen, broad-spectrum antibiotics (covering oral flora and gut organisms), analgesia
-Nasogastric tube decompression
-Nil per os
-Transfer to a facility capable of surgical intervention.
Medical Management:
-Broad-spectrum IV antibiotics are crucial to combat mediastinitis
-Early administration is vital
-Antiemetics if vomiting persists
-Pain control with IV analgesics.
Surgical Management:
-Surgical repair is the mainstay for Boerhaave syndrome
-Indications: Transmural perforation, hemodynamic instability, failure of endoscopic management, significant contamination
-Procedures: Thoracotomy with esophageal repair (primary closure with or without buttressing with pleura/diaphragm/gastric flap), esophagectomy with cervical esophagostomy and gastrostomy (in extensive or delayed cases), or esophageal diversion
-Thoracic drainage is always performed.
Supportive Care:
-Nutritional support via parenteral nutrition or jejunostomy feeding
-Close monitoring of vital signs, fluid balance, and sepsis markers
-Chest tube management and monitoring of output
-Wound care for thoracotomy incision.

Complications

Early Complications:
-Mediastinitis
-Sepsis and septic shock
-Respiratory failure
-ARDS
-Anastomotic leak (if primary repair)
-Bleeding.
Late Complications:
-Esophageal stricture
-Esophageal dysmotility
-Tracheoesophageal fistula
-Recurrent perforation
-Chronic pain syndrome.
Prevention Strategies:
-Prompt diagnosis and surgical intervention
-Aggressive antibiotic therapy
-Careful surgical technique with adequate repair and coverage
-Early institution of nutritional support
-Postoperative vigilance for signs of leak or infection.

Prognosis

Factors Affecting Prognosis:
-Time to diagnosis and treatment is the most critical factor
-Extent of esophageal injury
-Presence of comorbidities
-Degree of mediastinal contamination and sepsis
-Patient's overall condition.
Outcomes:
-Mortality rates remain high (20-50%), particularly with delayed treatment
-Early surgical repair within 24 hours significantly improves survival
-Survival rates decrease substantially with each passing day.
Follow Up:
-Regular outpatient follow-up is essential
-Esophagography or manometry may be required to assess esophageal function and rule out strictures
-Long-term nutritional monitoring and management of any sequelae.

Key Points

Exam Focus:
-Boerhaave syndrome is a spontaneous esophageal perforation
-Time to surgery is paramount
-Operative choices include primary repair, repair with buttressing, or esophagectomy
-Broad-spectrum antibiotics are critical.
Clinical Pearls:
-Always suspect Boerhaave syndrome in a patient with sudden severe chest pain after forceful vomiting
-Gastrografin esophagography is the investigation of choice for suspected perforation
-Early surgical consultation is mandatory.
Common Mistakes:
-Delaying surgical intervention
-Misdiagnosing as cardiac event or pulmonary embolism
-Inadequate antibiotic coverage
-Failure to consider esophageal rupture in a patient with a history of vomiting and chest pain.
