Oesophagectomy — operative approaches and complications
After oesophagectomy the commonest complication is respiratory (pneumonia), but the exam question is almost always an anastomotic leak — fever, tachycardia and atrial fibrillation on day 4–7 — diagnosed by CT with oral contrast or endoscopy, and treated by severity from drainage and a stent to reoperation if the gastric conduit is necrotic.
Why it matters in the exam
Three main approaches appear in the exam: Ivor Lewis — abdominal approach and right thoracotomy with an intrathoracic anastomosis; McKeown — three incisions (chest, abdomen and neck) with a cervical anastomosis; and the transhiatal approach (Orringer) — abdomen and neck without thoracotomy. The usual conduit is a gastric tube whose blood supply is based on the right gastroepiploic artery. A cervical anastomosis leaks more often, but a neck leak is less dangerous and is usually managed by opening the wound; an intrathoracic leak causes effusion, empyema and mediastinitis and is life-threatening. A minimally invasive approach reduces pulmonary complications.
The classic question: a patient on day 4 after Ivor Lewis with a fever of 38.5 degrees, tachycardia and new atrial fibrillation. New atrial fibrillation after oesophagectomy is a warning sign of a leak until proven otherwise. Diagnosis is by CT with oral contrast and endoscopy, which also shows the state of the conduit. The ECCG definitions grade a leak in three types: I — local, no change in treatment; II — needs non-operative intervention (drainage, a stent or an endoscopic vacuum system); III — needs surgery. Conduit necrosis requires urgent surgery, removal of the conduit and cervical oesophagostomy. Other complications: chylothorax (milky drainage after feeding starts, triglycerides above 110 mg/dL), recurrent laryngeal nerve palsy (more common with a cervical approach), anastomotic stricture (dilated endoscopically) and delayed gastric emptying.
Therefore every patient with signs of sepsis in the first days after oesophagectomy needs a rapid assessment of the anastomosis and the conduit, not just antibiotics.
Key points
- Ivor Lewis — anastomosis in the chest; McKeown — in the neck.
- Leak on day 4–7 with fever and atrial fibrillation.
- CT with oral contrast and endoscopy.
- Conduit necrosis — urgent surgery.
- Chylothorax — triglycerides above 110 mg/dL.
Summary table
| Complication | Clues | Treatment |
|---|---|---|
| Anastomotic leak | Day 4–7, fever, tachycardia, atrial fibrillation, effusion | By grade: drainage and antibiotics, stent or endoscopic vacuum, surgery |
| Conduit necrosis | Severe sepsis, black mucosa on endoscopy | Urgent surgery, conduit removal, cervical oesophagostomy |
| Chylothorax | Milky drainage, triglycerides above 110 mg/dL | Fasting or MCT, and if high output — thoracic duct ligation |
| Recurrent laryngeal nerve palsy | Hoarseness, aspiration | Swallow assessment; usually transient |
| Anastomotic stricture | Dysphagia after weeks | Endoscopic dilatation |
