392 Part III Esophagus
By this point, a separate midline abdominal incision will have been performed, and blunt dissection is begun on the esophagus from the abdomen. A two-team approach should be considered with one team at the neck, while the other pre­pares the gastric conduit. e gastric conduit is elevated to the neck with traction and the gastroesophageal junction is divided. e pharyngogastrostomy anastomosis is performed using a single-layer, interrupted hand-sewn anastomosis with a nonabsorbable suture. e cervical tracheostomy is per­formed above the sternal notch. If too much trachea has been resected to allow for this, manubrial resection will permit placement of the end tracheostomy lower in the midline.
STRATEGY FOR LESIONS BELOW THE THORACIC INLET
Lesions below the thoracic inlet can be divided according to their location in the upper esophagus (below the tho­racic inlet but above the carina), midesophagus (between the carina and inferior pulmonary vein), or lower esophagus (below the inferior pulmonary vein). While we favor the tri­incisional approach for all malignant lesions (for reasons to be discussed later), lesions in the upper thoracic esophagus generally must be approached with this technique to ensure adequate proximal margins. If the lesion is in the midtho­racic esophagus, either the tri-incisional approach or the Ivor Lewis approach may be adequate. Lower esophageal tumors can be resected with either of these two approaches, or addi­tionally with a transhiatal approach or left thoracotomy and distal esophagectomy. With any resection, accommodation must be made for additional resection with reconstruction if frozen margins are involved with tumor.
Transhiatal Versus Transthoracic Techniques
Numerous retrospective analyses have been performed comparing the transhiatal to the transthoracic (mainly Ivor Lewis) approach. ese are summarized in two meta-analyses. Rindani and associates reviewed 44 trials involving either Ivor Lewis or transhiatal esophagectomy that were published in the English language between 1986 and 1996. plications, or pneumonia was no dierent between the two groups. Dierences were seen in the anastomotic leak rate (16% transhiatal vs 10% Ivor Lewis), stricture rate (28% transhiatal vs 16% Ivor Lewis), and incidence of recurrent nerve injury (11% transhiatal vs 5% Ivor Lewis). Mortality was higher after the Ivor Lewis approach (9.5%) than the transhiatal approach (6.3%). Long-term survival was about 25% with either technique. Hulscher and colleagues also performed a meta-analysis of 50 studies published between 1990 and 1999 involving transthoracic and transhiatal resection.

Overall, the incidence of bleeding, cardiac com-
23
Cardiac complications (20 vs 7%), anastomotic
leakage (24 vs 7%), and vocal cord paralysis (10 vs 4%) were higher in the transhiatal group as opposed to the transthoracic group. Pulmonary complications (19 vs 13%), in-hospital mortality (9 vs 6%), and operative time (5 vs 4.2 hours) were higher in the transthoracic group. Overall long­term survival was similar between the two groups (23% for transthoracic and 21.7% for transhiatal resections). ese reviews are retrospective and nonrandomized, and cau­tion should therefore be used in applying these ndings to individual institutions and patients.
ree prospective, randomized trials have been performed
comparing transhiatal to transthoracic resection. e rst was
24
published in 1993 by Goldmine and associates.
Sixty-seven patients younger than 70 years with squamous cell cancer were randomized to Ivor Lewis resection or transhiatal resec­tion. Operative time was longer (6 vs 4 hours) in the Ivor Lewis group. ere was no dierence in the incidence of pneumonia (20%), anastomotic leak, recurrent nerve injury, bleeding, perioperative mortality, or length of hospital stay. For those patients with nodal disease, however, none of the transhiatal patients was alive at 18 months, while 30% of the transthoracic patients were alive at 18 months.
Chu and coworkers randomized 39 patients with lower-
third esophageal cancers to either Ivor Lewis or transhiatal
25
resection.
Limitations of the study were small sample size, short follow-up (mean 15 months), and patient exclusions. Patients undergoing neoadjuvant therapy or those with forced expiratory volume in 1 second (FEV
) less than 70%
1
of expected were excluded. ere were no perioperative deaths in either group. Intraoperative hypotension occurred in 60% of transhiatal patients but only in 5% of transthoracic patients. ere was no dierence in blood loss, pneumonia, or recurrent nerve injury. e mean proximal margin was 3cm longer in the transhiatal group. No signicant dier­ence was seen in tumor recurrence or survival during the brief follow-up period.
A study comparing transhiatal resection to transthoracic, tri-incisional en bloc resection for distal adenocarcinoma of the esophagus or cardia was performed in the Netherlands. One hundred and six patients were randomized to tran­shiatal resection and 114 patients to transthoracic resec­tion. In-hospital mortality was 2–4% in each group. Chyle leak was higher in the transthoracic resection group (10 vs 2%). Respiratory complications including atelectasis and pneumonia were higher in the transthoracic group (57 vs 27%). Although statistical signicance was not reached, 39% of the transthoracic group was alive at 5years, while
26
only 29% of the transhiatal group survived 5years.
Meta­analyses show that the incidence of bleeding, ischemic cardiac events, and length of stay are not necessarily dier­ent between the transthoracic and transhiatal approaches. Placement of the anastomosis in the cervical position appears to increase the risk of recurrent laryngeal nerve injury, anastomotic leak, and stricture. e mortality rate from an anastomotic leak, however, is less than that of a leak in the chest. e transthoracic approach increases operative time and in-hospital mortality.
Chapter 18 Surgical Procedures to Resect and Replace the Esophagus 393
An update of this study following with a full 5-year follow-up
continued to show no statistically signicant overall survival in
27
either approach.
However, in a subgroup of patients who had one to eight positive lymph nodes in the resection specimen, the transthoracic approach (TTE) demonstrated improved overall survival compared with the transhiatal approach (THE) (39% TTE vs 19% THE, p = .05). Disease-free survival was similarly improved with the transthoracic approach (64% TTE vs 23% THE, p = .02).
e randomized trials show no statistically signicant dierence in survival, but they are small, and trends toward improved survival are observed in patients undergoing transt­horacic dissection. No dierence in mortality, blood loss, or
A
incidence of pneumonia was detected. It should also be noted that unlike the meta-analyses, the randomized trials showed no dierence in recurrent nerve injury or anastomotic leak. is is a testament to the importance of experience and volume in preventing these complications. Wong noted intra­operative hypotension in 60% of transhiatal dissections, but
28
in only 5% of transthoracic dissections.
is nding con­rms every surgeon’s experience with transhiatal resection. While some may argue that transhiatal dissection may be less taxing on an elderly or debilitated patient (either because of shorter operative time or avoidance of a thoracotomy), the operation may be more taxing to a patient with severe car­diac valvular or atherosclerotic disease who cannot tolerate uctuations in blood pressure. In these patients, transthoracic esophagectomy is safer.
SURGICAL APPROACHES TO LESIONS BELOW THE THORACIC INLET
Tri-incisional Esophagectomy (McKeown Technique)
e tri-incisional technique of esophageal resection combines the most attractive aspects of the Ivor Lewis and transhiatal approaches. It allows for dissection of the intrathoracic esophagus under direct vision with complete nodal resection and brings the anastomosis to the neck, allowing for maximal proximal mar­gins and minimizing the risk of an intrathoracic leak.
Under general anesthesia, bronchoscopy is performed to rule out tracheal or bronchial (most commonly left main bronchial) involvement with tumor. Esophagogastroduo­denoscopy is performed to localize the tumor and rule out disease of the stomach or duodenum. e patient is then rein­tubated with a double-lumen endotracheal tube and placed in the left lateral decubitus position. A right posterolateral thoracotomy incision is made large enough, approximately 10 cm in length, to introduce the surgeon’s hand (Fig. 18-3). e serratus muscle is spared. Division of the intercostal muscles anteriorly and posteriorly often permits adequate rib spread­ing without the need to remove a small portion, or shingle, a rib. e chest is entered through the fth or sixth inter­space depending on the location of the tumor. e inferior

pulmonary ligament is divided using electrocautery, and the lung is retracted anteriorly.
Dissection of the esophagus begins at a point away from tumor and any associated scarring, and the esophagus is encircled with a Penrose drain. Traction on the Penrose drain allows for cautery dissection encompassing all adjacent nodes. Arterial branches directly o the aorta are clipped or ligated. e settings on the electrocautery should be low when cau­terizing near the trachea. e azygos vein is typically divided, although this is not always necessary (Fig. 18-4). At this level, the vagus nerves are identied. Dissection cranial to this level involves the vagus nerves; the vagus nerves are peeled o and away from the esophagus to avoid injury to the recurrent vagus branches.

FIGURE 18-4 e esophagus has been isolated circumferentially at
a point superior to the tumor and encircled with a Penrose drain. An endostapling device is used to divide the azygos vein near its caval connection.
Dissection between the trachea and esophagus must be done with care and with low cautery dissection to avoid injury to the membranous trachea. Much of the dissection high in the chest can be done bluntly (Fig. 18-5). e cranial aspect of the dissection is complete when one’s ngers reach easily above the rst rib. e Penrose drain is knotted and passed into the lower neck with the knot against the ver­tebral body for later retrieval during the neck phase of the dissection (Fig. 18-6).
Another Penrose drain is used to gain traction on the lower esophagus and dissection continues caudally. All tissue between the pericardium, aorta, and azygos vein is dissected and incorporated into the specimen. No eort is made to resect the thoracic duct, although it is sometimes injured. For tumors near the gastroesophageal junction, a rim of diaphragm is incorporated into the specimen. e knotted Penrose drain is placed in the abdomen for later retrieval (Fig. 18-7). At this point, careful inspection is made for hemostasis and injury to the thoracic duct. Often, injury to the thoracic duct is evident when slightly cloudy or crystallized uid is seen pooling in the region of the duct. If an injury to the duct is seen, it should be closed with a pledgeted ne suture such as 5-0 Prolene. Mass ligature of the duct, as it enters the chest, is then performed by encompassing all tissue between the spine,
aorta, and azygos vein at the level of the hiatus with a 0 silk suture. A 28F straight chest tube is inserted via a separate stab incision and directed to the apex of the chest. An additional hole in the tube can be made to facilitate dependent uid drainage. e ribs are reapproximated with 2-0 Vicryl sutures.

e latissimus layer is closed using a running 0 Vicryl suture. A subdermal layer is closed with 2-0 Vicryl and the skin is closed in subcuticular fashion.
e patient is placed in the supine position and is reintu­bated with a single-lumen tube. A roll is placed under the back to permit neck extension, and the head is turned to the right. A midline laparotomy is performed from the umbilicus to the xiphoid. Exploration of the abdomen should include a care­ful palpation of the liver and inspection of the serosal surfaces for tumor implants. Palpation of the GE junction and proxi­mal stomach should be performed to rule out gastric spread of tumor. e left lobe of the liver is mobilized and retracted to the right. e Penrose drain left from the chest dissection is used for retraction of the GE junction (Fig. 18-8). e gas­troepiploic artery is identied and palpated. e pulse should be easily palpable provided the patient has a physiologic blood pressure. Staying at least 2 cm away from the gastroepiploic artery, the lesser sac is entered. Dissection continues cranially on the stomach along the greater curvature. Dissection may be performed by dividing tissue and ligating with 2-0 silk ties or by using an ultrasonic scalpel. e stomach is retracted medi-

ally and the omentum laterally. e artery itself should not be grasped or used for retraction. e gastroepiploic arcade ends near the point where the short gastric arteries begin. A pack placed behind the spleen often aids in exposure of the short gastric vessels (Fig. 18-9). e short gastric vessels can be ligated, double-clipped, or divided with an ultrasonic scalpel. Large vessels should be tied. Care should be taken not to incor­porate stomach wall in the ligature, as this may result in delayed necrosis of stomach wall and a postoperative intrathoracicleak.

FIGURE 18-9 Gastric mobilization is begun at the superior greater
curvature near the hiatus. A rolled Mikulicz pad is placed behind the spleen to aid in exposure. e short gastric vessels between the spleen and the stomach are divided, and the transition zone between the left and right gastroepiploic arteries is identied. Mobilization proceeds at least 2 cm away from the right gastroepiploic arcade (dotted line).
Dissection on the greater curvature proceeds to the hiatus and is complete when the Penrose drain is reached.
Proximal dissection on the greater curvature of the stomach proceeds in likewise fashion. e gastroepiploic artery migrates farther from the stomach as one dissects toward the pylorus, and care must be taken not to injure the vessel. e gastrohepatic ligament is divided with cau­tery up to the GE junction. e stomach is lifted anteriorly, and thin adhesions between the stomach and pancreas are divided with cautery. e left gastric vessels are approached from behind the stomach (Fig. 18-10). e vessels are skel­etonized, and lymph nodes are swept up onto the speci­men. e vessels are clamped with a vascular endoscopic 30-mm stapler. e gastroepiploic pulse should be palpated at this time to ensure that the celiac axis itself has not been clamped, and the stapler is then red. e duodenum is then mobilized using a Kocher maneuver, bringing it to the midline (Fig. 18-11). A pyloromyotomy or pyloroplasty may be performed with equivalent ecacy in aiding gastric emptying. If a pyloroplasty is performed, it is best to close it in a single layer with interrupted (3-0 silk) sutures. A leak is exceedingly rare.
A neck incision is then made 6 cm in length along the anterior border of the left sternocleidomastoid muscle start­ing at the sternal notch. Deep to the platysma, dissection proceeds medial to the sternocleidomastoid muscle and carotid sheath and lateral to the thyroid. e omohyoid

can be divided with cautery (Fig. 18-12). Blunt dissection is then used to approach the vertebral bodies (Fig. 18-13). Lying along the vertebral body, the Penrose drain is grasped and brought out into the neck wound with the encircled esophagus. Proximally, the esophagus can be gently mobi­lized. e nasogastric tube is removed, and the esophagus is divided with a GIA 75-mm stapler (Fig. 18-14). A 2 silk suture is attached to the proximal margin, and the specimen is drawn out into the abdomen (Fig. 18-15). e cervical end of this tie is fastened to a clamp.

muscle reected laterally. Finger dissection beneath the omohyoid muscle develops a plane to the knotted Penrose drain. Inset: e patient is placed supine for the neck and abdominal incisions (outlined).
e gastric tube is then constructed by resecting the GE junction and the lesser curvature of the stomach down to the crow’s foot of veins with a series of thick tissue 75-mm gastrointestinal anastomosis (GIA) staplers (Fig. 18-16). A narrow gastric tube is believed to aid in emptying; however,
a diameter of less than 5–6 cm may compromise conduit perfusion. e right gastric artery along the lesser curvature can be divided in order to allow elongation of the conduit (Fig. 18-17). e specimen is removed, and frozen sections are performed on the margins. Inspection for hemostasis is

made of the gastric bed. e esophageal hiatus should admit four ngers. One ampule of IV glucagons is administered to ensure relaxation and lengthening of the gastric conduit. e silk tie that traverses the mediastinum is then attached to the valved end of a Foley catheter with a 30-cc balloon (Fig. 18-18). An endoscopic camera bag is secured around the 30-cc balloon (Fig. 18-19). e conduit is advanced into the bag, ensuring appropriate orientation. Suction is applied to the bag via the Foley catheter, and the conduit is drawn up into the neck incision (Fig. 18–20). e assistant must actively guide the conduit through the hiatus. At the end, the pylorus should sit at the hiatus.
e neck anastomosis can be hand-sewn using inter­rupted full-thickness 3-0 silk sutures (Fig. 18–21). e anastomosis may also be stapled in side-to-side, functional end-to-end fashion. A portion of the esophageal staple line is removed, an enterotomy is created on the posterior aspect of the gastric tube, and a linear GIA 75-mm stapler is inserted to create the anastomosis (Fig. 18–22). An additional re of an endoscopic 30-mm stapler may be used to gain additional length on the anastomosis. e enterotomy is usually closed with a TA 30 or 60 stapler after guiding the nasogastric tube down toward the hiatus. Hybrid anastomosis has been described with the back wall of the anastomosis created using a 30-mm stapler and the anterior wall closed with sutures. A

soft drain should be placed posterior to the anastomosis and the platysma and skin are closed separately. It is wise to use an interrupted closure, as this will allow for reopening of a portion of the wound should a cervical leak develop. Before closing the abdomen, a J-tube should be inserted at a point approximately 40 cm distal to the ligament of Treitz. e fascia is closed using a #2 running monolament suture and the skin is closed with staples.
Ivor Lewis Technique
e patient is placed in the supine position. Bronchoscopy to rule out tracheobronchial invasion and esophagoscopy to conrm the location of the tumor are performed. An upper midline incision is made from the umbilicus to the xiphoid. e abdominal phase of this operation is identical to the pre­viously described tri-incisional technique. Enlargement of the hiatus and dissection of the lower esophagus are more easily performed through the abdomen than through a high thora­cotomy incision. e GE junction and lesser curvature of the stomach are resected using a GIA stapler. e specimen is left attached to the esophagus to facilitate mobilization into the chest. A J-tube is placed before closing the abdomen.
A double-lumen endotracheal tube is placed and the patient is repositioned in the left lateral decubitus position. A right posterolateral thoracotomy is performed, and the chest is entered through the fourth or fth interspace. e azygos vein is divided and the intrathoracic esophagus is dissected. All lymphatic tissue is included with the esophagus. Because a gross margin of 5 cm, and ideally 10 cm, is desired, the anas­tomosis is usually performed high in the chest at or above the level of the azygos vein. e proximal esophagus is dissected only several centimeters above the proposed level of transec­tion to preserve its blood supply. e mobilized stomach is pulled up into the chest. e anastomosis can be constructed using an EEA stapler or hand-sewn technique. If a hand-sewn anastomosis is chosen, a double-layer technique is advis­able (Fig. 18-23). In 1942, Churchill and Sweet described a method of double-layer anastomosis that is still often used

A circle of stom­ach serosa 2 cm in diameter is scored and the underlying gas­tric vessels are ligated with 4-0 silk sutures. e back outer layer of the anastomosis is constructed with interrupted 4-0 silk horizontal mattress sutures. ese are placed 4 mm away from the serosal edge. Full-thickness stomach and esophageal wall are used. e esophagus is opened with a sharp instru­ment and the inner layer is constructed with interrupted suture incorporating esophageal mucosa and full-thickness stomach edge. e nasogastric tube is passed after completion of the posterior wall. A continuous Connell suture may also be used. e anterior outer layer anastomosis is constructed with 4-0 silk horizontal mattress sutures. e anastomosis should be wrapped or buttressed with omentum. At all times, atrau­matic handling of mucosal edges and tying of sutures without crushing of tissues are advised. Some surgeons advise tacking

the edge of the stomach wall to mediastinal tissue or paraver­tebral fascia to decrease tension on the anastomosis, although it is not clear if this is necessary. A 28F straight chest tube is placed into the apex of the chest via a separate stab inci­sion. e chest is closed with interrupted #2 Vicryl paracostal sutures, followed by a 0 Vicryl running latissimus layer, a 2-0 Vicryl running subdermal layer, and a 3-0 Vicryl subcuticular layer. Postoperative toilet bronchoscopy should be performed.
Transhiatal Technique
CONSIDERATIONS
We believe that a tri-incisional approach gives better expo­sure to the thoracic esophagus, allowing for a safer and wider resection and better lymphadenectomy. As discussed, there may be survival advantages to the radical resection permit­ted by the transthoracic technique, although trials to date have not shown a statistically signicant survival advantage using this approach. In cases in which the thoracic esophagus is not involved with tumor (either high-grade dysplasia or a laryngeal tumor involving the proximal esophagus), the tran­shiatal technique may be performed with equivalent onco­logical ecacy.
TECHNIQUE
e patient is placed in the supine position with the head rotated 45 degrees to the right. e abdominal phase of the operation is performed in identical fashion to that described in the tri­incisional section above. An upper-hand retractor is useful in elevating the sternum and costal margin. e phrenoesophageal ligament is divided using cautery, and the lower esophagus is
encircled with a 1 in wide Penrose drain. e phrenic vein must rst be identied and ligated. is will also enlarge the win­dow for dissection of the intrathoracic esophagus. e hiatus is dilated to allow entry of the surgeon’s hand. Arterial branches from the aorta are clipped on the aortic side and divided using cautery. in handheld malleable retractors are used to retract either side of the pleura during the dissection. Dissection under direct vision is usually possible up to the level of the inferior pulmonary veins.
At this point, an incision is made in the left neck along the anterior border of the sternocleidomastoid muscle starting at the sternal notch and extending 6–8 cm. e platysma is divided. e sternocleidomastoid muscle and carotid sheath are retracted laterally. e omohyoid is often divided. e middle thyroid vein is ligated and divided. A retractor may be used but must not rest on the recurrent nerve in the trache­oesophageal groove. e esophagus is palpated anterior to the spine and posterior to the trachea. Sharp dissection is carried out immediately on the esophagus, separating the esopha­gus from the membranous trachea and recurrent nerve. e esophagus is looped with a 1-in Penrose drain.
Blunt dissection of the posterior plane of the esophagus is performed rst. From the abdomen, the surgeon’s hand is placed in between the spine and esophagus with the palmar aspect of the ngertips immediately against the esophagus (Fig. 18-24). is is performed in conjunction with raising the esophagus anteriorly with the aid of the Penrose drain. An identical maneuver is performed through the cervical incision. When sucient dissection has been done from either side, both hands are introduced simultaneously and an attempt is made to touch ngertips. Intervening loose areolar tissue must then be torn, uniting the ngertips. If the surgeon’s ngertips will not reach from the neck, a sponge stick can be used. While the surgeon’s hand is behind the
