Esophageal perforation: causes, diagnosis and emergency management

Esophageal perforation is a full-thickness tear in the oesophageal wall that allows air, food or gastric contents to escape into the mediastinum or neck. Although uncommon, it can cause mediastinitis, sepsis and respiratory failure within hours.

The immediate priorities are to recognise a leak, keep the patient nil by mouth, control contamination and sepsis, and obtain urgent source control. The clinical pattern ranges from sudden pain after forceful vomiting to a delayed postoperative chest infection, so a reassuring early examination does not always exclude danger.

Causes and risk patterns

Forceful vomiting or retching can produce a spontaneous rupture, traditionally called Boerhaave syndrome. Sudden severe chest or upper-back pain during or after vomiting, especially with reflux, alcohol use or an eating disorder, should trigger urgent assessment. A Mallory-Weiss tear is only a mucosal laceration, but the distinction is vital because a full perforation requires source control.

Endoscopy, dilation, stent placement, oesophageal surgery and nasogastric tube insertion can all cause iatrogenic perforation. Previous surgery, radiation, malignancy and pre-existing strictures increase vulnerability, while swallowed foreign bodies, batteries, corrosive fluids or chest trauma can cause direct injury.

Recognising the warning signs

Pain with swallowing (odynophagia), fever, tachycardia and breathlessness are common, while crepitus from subcutaneous emphysema in the neck or chest may indicate escaping air. Pain can radiate to the shoulder, jaw or abdomen, leading to confusion with myocardial infarction, pulmonary embolism, aortic dissection, pneumothorax or pancreatitis.

The presentation changes with time. Early patients may have few examination findings; later deterioration may include hypotension, confusion, oliguria and sepsis. Elderly, immunocompromised and postoperative patients may report only vague pain, so unexplained sepsis after upper-GI instrumentation needs urgent review rather than observation.

Tests that guide treatment

A stable patient with suspected perforation usually begins with CT of the chest using oral contrast to locate extraluminal gas or fluid, define contamination and identify complications. Blood tests should include full blood count, renal and liver function, lactate, coagulation and blood cultures. A water-soluble contrast esophagram can demonstrate a leak when CT is inconclusive.

If the patient is haemodynamically unstable, resuscitation and bedside assessment come before transfer for CT. Endoscopy may identify the defect or guide treatment, but it is used selectively because insufflation can worsen contamination; it is generally avoided in an uncontrolled leak.

Emergency priorities and decision checkpoints

Initial care follows an emergency and sepsis pathway: nil by mouth, oxygen, monitoring, intravenous access, cautious fluids, analgesia and broad-spectrum intravenous antibiotics. Early upper-GI or foregut surgical review is required, with intensive-care involvement particularly when there is organ dysfunction, sepsis or respiratory compromise.

The team must decide whether the injury can be observed safely or needs drainage, repair, diversion or a combination. Antibiotics should be reviewed daily, and deterioration in circulation, lactate, breathing or pain should trigger immediate escalation.

Immediate clinical priorities include:

• Keep the patient nil by mouth and avoid oral food or medication.
• Start oxygen, monitoring, intravenous access, fluids and analgesia.
• Send blood cultures and obtain urgent contrast imaging when stable.
• Involve a senior upper-GI surgeon early.

Four checkpoints should be reassessed throughout care:

• Reassess airway, breathing, circulation, lactate and urine output.
• Look for mediastinitis, pleural contamination, necrosis or fistula.
• Escalate for worsening pain, fever, shock, confusion or respiratory failure.
• Record the source-control plan, antibiotic review date and responsible clinician.

Australian care pathways

In Australia, an acute presentation should prompt a 000 (triple-zero) call for ambulance transport or immediate attendance at an emergency department; staff triage suspected perforation as a time-critical condition. Australian hospitals commonly use the terms upper GI and foregut teams for services treating the oesophagus, stomach and proximal bowel, which helps when requesting surgical help.

Melbourne, Sydney and Adelaide have tertiary hospitals with endoscopic, radiology and foregut teams. In regional and remote Australia, distance can make transfer lengthy, so early discussion with a receiving centre and services such as the Royal Flying Doctor Service or an interstate retrieval team may be necessary. Telehealth can support the initial assessment but cannot replace urgent imaging or resuscitation.

Australia’s Medicare and public hospital system underpin emergency care, while private cover and hospital agreements influence transfers, private admissions and elective reconstruction. Some remote and Aboriginal and Torres Strait Islander patients may need additional support for communication, travel and culturally safe care.

Choosing operative or conservative care

Early source control, often within 24 hours, is usually preferred when the diagnosis is prompt, contamination is limited and the patient is fit for surgery. The operation may involve primary repair, drainage and debridement, diversion, or a combination; delayed cases often need extensive drainage and management of an underlying cancer or foreign body.

Conservative treatment is appropriate only for selected, stable patients with a contained leak, minimal contamination, no sepsis and close specialist access. It combines nil by mouth, antibiotics, nutritional support and serial imaging, with surgery reconsidered if the patient deteriorates. Endoscopic stenting may be considered in selected cases by the multidisciplinary team.

Recovery and long-term follow-up

After source control, patients may need prolonged ventilation, renal support, nutritional rehabilitation and management of strictures or a fistula. Dietetic and speech-pathology input can protect nutrition and swallowing, while follow-up should track weight, hydration, pain, respiratory symptoms and quality of life rather than relying only on imaging.

The ISDE 2021 virtual programme’s discussion of patient-reported outcomes reinforces this whole-person focus: recovery may be slower than expected, and structured symptom reporting can reveal disability that operative notes miss. Such measures also help teams compare treatments and plan rehabilitation.

For sudden chest or back pain after vomiting, or rapidly worsening pain, fever or breathlessness after an oesophageal procedure, the next step is immediate emergency-department assessment, followed by nil-by-mouth care, sepsis treatment and urgent upper-GI surgical review.
