Esophagectomy Techniques There are many ways to perform an esophagectomy. The method your surgeon uses will depend on the location of your tumor.
TranshiatalEsophagectomy • In this method, the surgeon makes incisions in the neck and abdomen. Most of the esophagus is removed through these incisions. Because there’s no incision in the chest wall and the lungs do not have to be deflated for the surgeon to reach the esophagus, this method may result in fewer complications, such as pneumonia. Typically the surgeon attaches the stomach to the remaining esophagus in the neck. Sometimes, a segment of the colon is used to connect the esophagus to the stomach.
Ivor-Lewis EsophagectomyIn this method, the surgeon makes one incision in the abdomen and one in the chest along the ribs. The lower half of the esophagus is removed through the abdominal incision, and the stomach is attached to the upper esophagus in the chest.
Total EsophagectomyThis surgery is used to remove the entire esophagus when there are large tumors in the middle of the esophagus. The surgeon makes incisions in three places: the abdomen, chest, and neck. The esophagus is separated from other chest structures and organs through these incisions, and then it’s removed. The surgeon will create a new passage for food from the throat to the stomach, typically with a segment of the small intestine or colon.
Minimally Invasive SurgeryFor many patients, surgeons can use a minimally invasive approach to remove the part of the esophagus affected by cancer.
