Stem

A 64-year-old man, 76 kg, with a distal esophageal adenocarcinoma, is scheduled for a minimally invasive Ivor Lewis esophagectomy after neoadjuvant chemoradiation: laparoscopic gastric mobilization, then right thoracoscopy with an intrathoracic anastomosis. He has lost 9 kg, regurgitates food at night, and smoked until diagnosis. FEV1 is 74% predicted. Hemoglobin is 11.4 g/dL and albumin 3.1 g/dL.

Question

What is your anesthetic plan?

Ideal answer

HeadlineThree things decide this case: aspiration at induction, his lungs through one-lung ventilation, and blood flow to a gastric conduit that lives on perfusion pressure.

  1. Head-up rapid sequence induction: an obstructed esophagus holds food above the tumor, whatever the fasting time.
  2. Left double-lumen tube, confirmed by bronchoscope, for right-chest collapse with protective one-lung ventilation.
  3. Thoracic epidural or paravertebral catheter: epidural pain control lowers pulmonary complications, but its hypotension, 20–76%, threatens the anastomosis.1
  4. Goal-directed fluid with MAP above 65–70, because rigid restriction leads to high-dose catecholamines and conduit ischemia.1
  5. Extubate in the room if criteria are met: early extubation was linked to fewer pulmonary complications.2

Watch for: the conduit's color, stroke volume variation, and the airway pressures and oxygenation while the right lung is down.

Breaking down the answer

  • Regional choice — paravertebral or erector spinae blocks give comparable analgesia with steadier pressure and less vasopressor need.1 Changes if: anticoagulation or a failed epidural; I still need a plan before he wakes.
  • Which pressor — in one cohort of 208 Ivor Lewis patients, intraoperative vasopressin carried four times the leak odds, and phenylephrine alone had the lowest leak rate, 3.6%.3 Observational, but I limit high-dose alpha agonism and vasopressin.
  • Volume itself — crystalloid around 5 mL/kg/h and fluid balance did not predict leak there;3 what matters is avoiding both overload and hypovolemia.1
  • Recurrent laryngeal nerve — palsy occurred in 24% in a meta-analysis, mostly McKeown three-field operations with neck dissection.4 It raised pneumonia (RR 1.82), reintubation (RR 3.83) and leak (RR 1.52).4
  • Protect the conduit — no blind gastric tube or probe passed after the anastomosis without the surgeon; routine nasogastric decompression is safer than omitting it.1

Follow-up question

During the thoracic phase, after a 5 mL epidural bolus, his MAP falls to 56 mmHg with a heart rate of 64. The surgeon is fashioning the anastomosis and asks you not to give "any pressors, because of the conduit." What do you do?

Follow-up answer

HeadlineThis is epidural sympathectomy, and hypotension is the bigger threat to the conduit; I say so and treat it.

I check for bleeding, caval compression and auto-PEEP, and look at stroke volume variation. If he is fluid-responsive, I give a bolus; otherwise phenylephrine in small doses to a MAP above 65–70, minimizing the alpha burden.1 I hold further epidural boluses, run a dilute infusion, and avoid adding vasopressin.3 I tell the surgeon the target and reassess every few minutes.

Pitfalls that cost points

  • Treating every postoperative hoarse voice as intubation trauma: check the cords before he eats.
  • Forgetting his future anesthetics: aspiration risk after esophagectomy is lifelong.5

Rapid-fire

Q: How common are aspiration events when post-esophagectomy patients are induced later? A: In 131 reported inductions, regurgitation occurred in 5.3% and aspiration in 9.9%.5

Q: How are they usually induced? A: Semi-Fowler position in 93% of reported cases, with rapid sequence in 59%.5

Q: Why does leak matter so much? A: It is the procedure's main complication; in the cohort, leak meant longer stays, more readmission and more reintubation (31% vs 12%).3

Q: How often do lymph nodes involve the recurrent laryngeal nerve chain? A: In 30–50% of thoracic esophageal cancers, which is why surgeons dissect there and risk palsy.4
