Oesophageal Injury After Anterior Cervical Spine Surgery
Clinical Features and Presentation
- Physical examination and laboratory studies alone are not reliable for early diagnosis of esophageal injury in patients after anterior cervical spine surgery 3
Diagnostic Approach
- Contrast-enhanced CT and CT esophagography should be performed in hemodynamically stable patients with suspected esophageal injury, with high sensitivity (95%) and specificity (91%) 4
- Flexible endoscopy is recommended as an adjunct to CT, providing direct visualization of the injury site and can alter surgical management in up to 69% of patients 4
- In unstable patients requiring immediate surgery, intraoperative endoscopy can be employed to rule out esophageal perforation 4
- Triple endoscopy (esophagoscopy, laryngoscopy, and bronchoscopy) is indicated as injury to one structure should raise suspicion of damage to adjacent organs 4
Management Principles
- Operative repair is the treatment of choice for traumatic injuries of the esophagus, according to the American College of Surgeons 1, 2
- Debridement of non-viable tissue around the perforation is a key surgical principle 2
- Primary closure of the esophageal defect when feasible is recommended 2
- The mucosal defect is often longer than the muscular tear; longitudinal myotomy at both ends helps expose mucosal edges for appropriate repair 1
- Two-layer repair with separate suturing of the mucosa and muscle is traditionally recommended 1
- Buttressing the repair with vascularized tissue (muscle flap) decreases the risk of leakage 1, 2
- Adequate drainage around the repair site is necessary 1
- Decompression of the esophagus and stomach via nasogastric tube is recommended 1
Non-Operative Management
- Non-operative management can be considered only in highly selected patients with early presentation, contained esophageal disruption, and minimal contamination of surrounding spaces 1, 4
- Requires nil per os status, broad-spectrum antibiotic coverage, nasogastric tube placement, early nutritional support, and intensive monitoring in an ICU setting 1, 4
Complications and Outcomes
- Common complications include pneumonia 2, mediastinitis 4, sepsis 1, and acute respiratory distress syndrome 4
- Mortality rate ranges from 3.92% to 50% without appropriate management 2
- Early diagnosis and immediate treatment are crucial for survival, as 92% of deaths occur within 24 hours 1
Important Caveats
- Treatment should be undertaken in specialized centers with multispecialty expertise (esophageal surgeons, interventional radiologists, endoscopists, intensive care specialists) 3
