An esophagectomy is a surgical procedure to remove part of the esophagus and remains a formidable surgery with high morbidity and mortality. It is performed for esophageal cancer and non-malignant conditions including hiatal hernias, severe GERD refractory to medical management, esophageal strictures and diverticula, and dysmotility disorders such as achalasia.
Anesthetic management depends greatly on the surgical approach. Notably procedures using a thoracic approach typically require one-lung ventilation, while transhiatal procedures do not (see procedure variants for details). The primary anesthetic goals include prevention of tracheal aspiration, lung protective ventilatory strategies, multimodal pain management which may include epidural analgesia, fluid management to optimize tissue oxygen delivery, and adequate perfusion to areas of anastomosis.
|Cardiovascular||Oxygen consumption increases 50% in the immediate post-op period. Patients need to be able to increase cardiac output and oxygen delivery after surgery.|
|Respiratory||Evaluate smoking history and underlying pulmonary dysfunction|
|Gastrointestinal||Patients have passive reflux following esophagectomy.|
|Hematologic||Hypercoagulability due to malignancy|
|Renal||Underlying renal insufficiency may be exacerbated|
Labs and studies
Operating room setup
Patient preparation and premedication
Regional and neuraxial techniques
- Thoracic epidural
Monitoring and access
- Invasive hemodynamic monitoring
- Large bore IV access
Induction and airway management
- May consider RSI if high-aspiration risk due to esophageal tumor obstructing food passage
- Left sided double lumen tube or single lumen ETT with bronchial blocker for one lung ventilation
- Start supine position for abdominal thorascopic approach
- Reposition to left lateral decubitus for thoracic anastamosis
- Supine throughout
Maintenance and surgical considerations
- Pt is placed supine and peritoneal cavity is examined for metastatic disease
- Lower portion of the stomach is mobilized
- Gastric conduit formed
- A cervical anastomosis is performed and esophagus and stomach returned to mediastinum
- Step-down unit for Enhanced-Recovery cases
- Epidural management
- Anastomotic leak
- Vocal cord paresis
- Recurrent laryngeal nerve injury
- Post-operative atrial fibrillation
- Morbidity requiring re-operation
Multiple variations of surgical approach are described in the literature. As opposed to traditional open surgery, surgeons have more recently favored minimally invasive thoracoscopic and laparoscopic approaches including robotic-assisted techniques. Minimally invasive approaches allow for optimal visualization within the thoracic cavity to reduce chances of injury during dissection, have reduced pulmonary complications, and shortened the time to recovery. Despite the variations, from the anesthesiologist's point of view there are two basic types of esophagectomy:
- Chiefly used for tumors in the lower esophagus and adenocarcinoma of the GE junction.
- Does not require one-lung ventilation. Resection is done entirely through the abdomen.
- Combined abdominal/thoracic resection
- Used for complete esophagectomy and tumors high enough in the esophagus that a thoracic approach is necessary.
- Require one-lung ventilation for the thoracic portion of the case (see also video-assisted thoracic surgery, or VATS).
- Two major procedure techniques
- Ivor-Lewis esophagectomy involves a traditional open laparotomy and open thoracotomy.
- The McKeown (or three-hole) esophagectomy, adds a third incision in the neck for cervical anastomosis in total esophagectomy. Recent reviews have demonstrated a higher incidence of complications with the McKeown approach.
