An '''esophagectomy''' is a surgical procedure to remove part of the esophagus and remains a formidable surgery with high morbidity and mortality.<ref name=":0">{{Cite journal|last=Ng|first=Ju-Mei|date=June 1, 2008|title=Perioperative Anesthetic Management for Esophagectomy|url=https://doi.org/10.1016/j.anclin.2008.01.004|journal=Anesthesiology Clinics|volume=26|issue=2|pages=293–304|doi=10.1016/j.anclin.2008.01.004|issn=1932-2275|via=}}</ref> It is performed for esophageal cancer<ref>{{Cite journal|last=Napier|first=Kyle J|date=2014|title=Esophageal cancer: A Review of epidemiology, pathogenesis, staging workup and treatment modalities|url=http://www.wjgnet.com/1948-5204/full/v6/i5/112.htm|journal=World Journal of Gastrointestinal Oncology|language=en|volume=6|issue=5|pages=112|doi=10.4251/wjgo.v6.i5.112|issn=1948-5204|pmc=PMC4021327|pmid=24834141}}</ref> and non-malignant conditions including hiatal hernias, severe GERD refractory to medical management, esophageal strictures and diverticula, and dysmotility disorders such as achalasia.


Esophageal cancer incidence has been increasing and is now the eighth most common malignancy worldwide. Despite overall poor prognosis with this malignancy, surgery plays a significant role to increase long-term survival and possible cure. Multiple variations of surgical approaches are described in the literature including [[Ivor Lewis esophagectomy|Ivor Lewis]] (IL)<ref>{{Cite journal|last=Lewis|first=I.|date=1946-07|title=The surgical treatment of carcinoma of the oesophagus; with special reference to a new operation for growths of the middle third|url=https://pubmed.ncbi.nlm.nih.gov/20994128|journal=The British Journal of Surgery|volume=34|pages=18–31|doi=10.1002/bjs.18003413304|issn=0007-1323|pmid=20994128}}</ref>, McKeown, and [[Transhiatal esophagectomy|transhiatal]] (TH). While an open approach was used traditionally, surgeons have more recently favored minimally invasive, thoracoscopic, approaches including robotic techniques. Minimally invasive approaches allow for direct visualization within the thoracic cavity to reduce chances of injury during dissection and have reduced the pulmonary complications and hastened the recovery period.
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|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.<ref>{{Cite journal|last=Jaeger|first=J.

An esophagectomy is a surgical procedure to remove part of the esophagus and remains a formidable surgery with high morbidity and mortality.[1] It is performed for esophageal cancer[2] 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.[3]

Preoperative management

Patient evaluation

System Considerations
Neurologic
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.
Pulmonary 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
Other

Labs and studies

Operating room setup

  • Double lumen tube with clamp prepared vs. ETT w/ bronchial blocker vs. ETT (depends on procedure variant)
  • Fiberoptic scope to evaluate ETT positioning
  • Large gauge NGT +/- bridal as patients remain NPO for >5 days postop
  • Arterial line setup
  • Significant amounts of crystalloid/colloid ready
  • Glucagon 1mg IV (institution and surgeon preference)

Patient preparation and premedication

Regional and neuraxial techniques

Thoracic epidural can be used for intraoperative analgesia, but more importantly can be used for postop pain management with PCEA.

Remember to tape the thoracic tube opposite the side of the thoracotomy incision--thus it should be usually taped to the left.

Intraoperative management

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 (R lung down)

Positioning

  • Ivor-Lewis
    • Start supine position for abdominal thorascopic approach
    • Reposition to left lateral decubitus for thoracic anastamosis
  • Transhiatal
    • Supine throughout

Maintenance and surgical considerations

  • Consider ketamine bolus (0.5 mg/kg) and gtt (0.2-0.5 mg/kg/hr) for pain management intraop
  • Surgeons may request glucagon for lower esophageal sphincter relaxation

Abdominal Dissection

  • 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

Emergence

Postoperative management

Disposition

  • ICU
  • Step-down unit for Enhanced-Recovery cases

Pain management

  • Epidural utilized for patient controlled epidural analgesia (PCEA)

Potential complications

  1. Anastomotic leak
  2. Vocal cord paresis
  3. Recurrent laryngeal nerve injury
  4. Post-operative atrial fibrillation[4]
  5. Morbidity requiring re-operation
  6. Mortality

Procedure variants

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.[5] Despite the variations, from the anesthesiologist's point of view there are two basic types of esophagectomy:

  1. Transhiatal
    1. Chiefly used for tumors in the lower esophagus and adenocarcinoma of the GE junction.
    2. Does not require one-lung ventilation. Resection is done entirely through the abdomen.
  2. Combined abdominal/thoracic resection
    1. Used for complete esophagectomy and tumors high enough in the esophagus that a thoracic approach is necessary.
    2. Require one-lung ventilation for the thoracic portion of the case (see also video-assisted thoracic surgery, or VATS).
    3. Two major procedure techniques
      1. Ivor-Lewis esophagectomy[6] involves a traditional open laparotomy and open thoracotomy.
      2. McKeown 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.[7][8]
