The lung is retracted anteriorly, and the mediastinal pleura opened over the section of esophagus
where the tumor resides. Depicted is a tumor at
the level of the azygos vein; in this case, the azygos vein is mobilized and divided with an endoscopic linear cutter/vascular stapler. The
esophageal myotomy is performed longitudinally
over the tumor with a hook cautery on low voltage
(2). The leiomyoma is enucleated by blunt dissection. Once freed, it is placed in an endoscopic bag
(3) to minimize tumor seeding as it is extracted through
one of the port sites.

Integrity of the mucosal layer is evaluated by insufflating air through
the esophagoscope while occluding the distal esophagus with a
sponge stick (4). Finally, the muscular layer of the esophagus
is closed with interrupted 4-0 silk sutures (5). A small
chest tube is left in the pleural space via the most inferior port site, closing the other ports.

Esophagogastrectomy: Separate
Abdominal and Thoracic Incisions
Operative Indications
Esophagogastrectomy performed through an upper midline abdominal incision and a right lateral thoracotomy incision (Ivor
Lewis esophagectomy) is used primarily to resect malignant neoplasms of the intrathoracic esophagus. Adenocarcinomas
arising in the middle and distal portion of the esophagus, generally from Barrett’s mucosa, and squamous cell carcinomas of
the middle and distal third of the esophagus are the usual indications. Before performing this procedure, patients with malignancies are usually staged with barium studies, endoscopy, endoscopic ultrasonography, and CT scans of the abdomen and
chest. A wide spectrum of patients is eligible for this procedure including patients with advanced disease, patients with
high-grade Barrett’s dysplasia, early-stage disease, and cancer downstaged with induction therapy. If there are widespread
liver metastases, ascites, or other evidence of extensive spread, other means of palliation for the dysphagia should be considered. The operative procedure can also be performed for benign strictures of the distal esophagus. Generally, however, when the esophageal pathology is benign, colon, instead of stomach, is used for replacement. Also, when an acute
perforation through a diseased distal esophagus is recognized immediately, this operative procedure can be considered.
Operative Technique
The patient is initially positioned supine, and the abdomen opened through an upper
midline incision. The abdomen is explored to be certain that extensive tumor dissemination does not exist, which would preclude the operative procedure. Exposure can be
greatly facilitated by the use of the upper hand retractor, which allows constant retraction of both costal margins from a frame attached to the operating room table. The left
lobe of the liver can be retracted in a cephalad direction or, as pictured here, the triangular ligament can be divided and the lateral segment of the left lobe of the liver

retracted to the right. In this illustration, the esophageal neoplasm is
distal, near the gastroesophageal

is mobilized, dividing the greater
omentum. Great care must be
taken to leave the right gastroepiploic vessels intact. The stomach’s
vascular supply will be derived pri-
marily from the pedicle of the right
gastroepiploic vessels and, to a less-
er extent, from the right gastric vessels.
The vasa brevia are divided, and the
spleen is left in situ (2).

Once the greater curvature of
the stomach has been mobilized
and the greater omentum divided,
leaving the right gastroepiploic vessels intact, the gastrohepatic ligament is opened (3).

axis or its other major branches, the splenic
and hepatic arteries. A replaced left hepatic
artery should be looked for; if one is found,
originating from the gastric artery, this vessel
should be dissected out and ligated as close
to the stomach as possible. An attempt should
be made to dissect the lymph nodes surround-
ing the celiac axis, and leave them on the stom-
ach (specimen) side.

The duodenum is extensively kocherized so that the stomach will
have maximum mobility to be drawn up into the right chest (6). A
portion of the lesser curvature is cleaned at a spot where the stomach
ultimately will be divided when it is up in the chest (7). This point
should be distal enough to allow any positive left gastric artery and
celiac axis lymph nodes to be on the specimen side.

Much of the dissection of the distal thoracic
esophagus can be performed bluntly
through the abdominal incision.
Since both vagus nerves are
removed with the specimen during the
esophagectomy, either a pyloromyoto-
my (preferred) or pyloroplasty is nec-
essary (8).
Both are described previously in “Short Segment
Colon Interposition for Benign Esophageal Stricture”
above. The stomach and duodenum have now been completely mobilized. The stomach will survive on the right gastroepiploic and right gastric vessels.
A feeding jejunostomy is created. A site 40 cm distal to the ligament of Treitz is chosen. Two purse-string sutures of 3-0 silk are placed,

one inside the other. An enterotomy is made, and a 16 French red rubber
catheter with several side holes is inserted through the purse-string sutures into
the distal jejunum (9). The sutures are then tied to hold it in place.

The enterotomy site is imbricated with several interrupted 3-0 silk
Lembert sutures. (10, 11). The jejunostomy tube is then
brought out in the left upper quadrant; the jejunal site is
tacked up to the anterior abdominal wall with interrupted 3-
0 silk sutures. The abdomen is irrigated and closed.

The patient is repositioned in preparation for a right lateral thoracotomy. The right
pleural cavity is entered through the fifth intercostal space. A short segment of the fifth
rib posteriorly can be removed to improve exposure if needed. The ribs are spread with
a self-retaining retractor. The mediastinal pleura is opened over the entire length of the
thoracic esophagus (12).

The distal portion of the esophagus,

including the tumor, has been dissected
free through the abdominal incision.
The esophagus is further mobilized
up to the azygos vein through the
thoracotomy incision using both
sharp and blunt dissection
(13). The azygos vein is ligated
and divided to aid in the most
cephalad portion of the dissection. When the entire thoracic
esophagus has been mobilized, the
stomach is pulled up through the
widened hiatus into the chest.
