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. Michael|last2=Collins|first2=Stephen R.|last3=Blank|first3=Randal S.|date=December 1, 2012|title=Anesthetic Management for Esophageal Resection|url=https://doi.org/10.1016/j.anclin.2012.08.005|journal=Anesthesiology Clinics|volume=30|issue=4|pages=731–747|doi=10.1016/j.anclin.2012.08.005|issn=1932-2275|via=}}</ref>

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]

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. 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.[7][8]
