Oesophageal Perforation
On this page
Direct answer
Severe chest pain and surgical emphysema after forceful vomiting — the Mackler triad of vomiting, lower chest pain and subcutaneous emphysema — signal Boerhaave syndrome, a spontaneous full-thickness tear of the left postero-lateral distal oesophagus that floods the mediastinum with gastric contents and kills through mediastinitis and sepsis. Diagnosis is by water-soluble contrast swallow (barium only if the water-soluble study is negative, because barium in the mediastinum worsens mediastinitis) plus contrast CT chest; broad-spectrum antibiotics, nothing by mouth and drainage start immediately. Operative primary repair buttressed with healthy tissue (intercostal muscle flap, fundoplication wrap or omentum) is standard for thoracic perforations recognised within about 24 hours; beyond 24 hours, or in gross contamination and instability, options widen to repair with wide drainage, oesophageal diversion with a cervical spit fistula and feeding jejunostomy, or oesophagectomy in a destroyed oesophagus. Cervical perforations, the usual iatrogenic injury, often respond to conservative management with antibiotics and drainage.
What you must remember
- Cause ranking: iatrogenic instrumentation is now the commonest overall (endoscopy, dilatation, sclerotherapy, intubation, foreign body removal); Boerhaave spontaneous rupture follows vomiting against a closed upper sphincter; foreign bodies and trauma contribute; caustic and post-emetic perforations dominate Indian emergency practice alongside instrumentation.
- Site logic: instrumental perforations cluster in the cervical oesophagus (cricopharyngeus) and thoracic inlet; spontaneous rupture tears the left postero-lateral wall of the lower third, just above the diaphragmatic hiatus — the weakest point lacking serosa.
- Mackler triad: vomiting, chest pain and subcutaneous emphysema; the pain is agonising, often mistaken for myocardial infarction, aortic dissection or perforated ulcer — the correct next test is contrast swallow, not troponin.
- Diagnosis sequence: erect chest X-ray (pneumomediastinum, left hydropneumothorax, subcutaneous emphysema, "V sign" of Naclerio), then water-soluble contrast swallow — sensitivity is imperfect, so a negative study with strong suspicion demands repeat water-soluble study or thin barium and CT; CT best defines mediastinal contamination and collections.
- The 24-hour rule: repair within 24 hours carries markedly lower mortality; after that delay tissues are inflamed and friable, so management shifts to wide drainage, repair with buttress when feasible, exclusion or diversion — delay is the strongest predictor of death.
- Location-specific management: cervical perforation (small, contained, no systemic sepsis) — NPO, antibiotics, IV fluids, drainage of neck collections, many close without surgery; intrathoracic perforation — primary two-layer repair with buttress (intercostal muscle, stomach wrap, omentum), pleural drainage, and drain/gastrostomy for nutrition; abdominal segment perforation — repair through the abdomen or via a thoracotomy if contaminated upwards.
- Late complications: oesophageal stricture (dilatate after healing), mediastinal fibrosis, empyema, tracheo- or aorto-oesophageal fistula (herald haematemesis after foreign body or malignancy), and short oesophagus.
How to work through a case
A 46-year-old man arrives eight hours after vomiting at a celebration meal with crushing lower chest pain, dyspnoea and crepitus over the neck; blood pressure is falling. Walk it as a sequence: airway and intravenous resuscitation, then the diagnosis — erect chest film shows pneumomediastinum and a left pleural effusion; water-soluble contrast swallow demonstrates extravasation from the distal oesophagus into the left pleural space. He is within 24 hours and has early sepsis: give antibiotics and fluids, place a chest drain, and take him to theatre. Through a left posterolateral thoracotomy (the left-sided, lower-third anatomy dictates the approach), the 2 cm tear is debrided and closed in layers over a bougie, buttressed with an intercostal muscle flap; a feeding jejunostomy is made for nutrition; drains sit in the mediastinum and pleura. He heals — but note the branches not taken: a small contained leak in a well patient eight hours after endoscopy could be treated conservatively with NPO, antibiotics and serial imaging; a patient presenting on day 4 in septic shock with a necrotic oesophagus is not a primary-repair candidate — he needs drainage, diversion (cervical oesophagostomy) and staged reconstruction; and a perforation through a known carcinoma or burnt caustic oesophagus is often best served by oesophagectomy with delayed reconstruction.
Where students slip
The first slip is choosing barium as the first contrast study — barium is reserved for the second look precisely because it inflames the mediastinum, so the safe sequence is water-soluble first. The second is applying the 24-hour rule as a cliff edge rather than a gradient: earlier is better, but the actual decision blends delay, degree of contamination, underlying oesophageal disease and physiological state. The viva favourite is the pain differential — Boerhaave mimics myocardial infarction, aortic dissection and perforated peptic ulcer, and the differentiating physical sign is subcutaneous emphysema with a clear ECG and unremarkable amylase.
Frequently asked questions
What is the Mackler triad?
Vomiting followed by severe lower chest pain and subcutaneous emphysema — the clinical signature of spontaneous oesophageal (Boerhaave) rupture.
Which contrast study is performed first for suspected perforation?
A water-soluble contrast swallow; barium is used only if this is negative but suspicion persists, because barium extravasating into the mediastinum aggravates mediastinitis.
Why does the 24-hour interval matter so much?
Mortality rises steeply after 24 hours because contaminated, inflamed tissue holds sutures poorly — early primary repair is usually sound, while late presentation needs drainage with or without repair, diversion or exclusion.
How is a thoracic primary repair reinforced?
With a vascularised buttress — intercostal muscle flap, gastric fundus wrap or omental patch — layered over the suture line to seal the repair against mediastinal contamination.
