divided esophagus, and the esophagus and top of the stomach are removed by pulling from the neck to leave the Penrose drain in the posterior mediastinum. The inferior end of the drain is then attached to the fundus of the stomach to serve as a guide to direct the stomach to the neck, where a two-layer anastomosis is performed to the cervical esophagus just above the thoracic inlet.

Perforation diagnosed several days after occurrence
Patients in whom the perforation is diagnosed several days after occurrence are treated primarily by interventional radi­ological techniques, although some authors have used opera­tive techniques. The strategy is to drain the cavity adjacent to the perforation and the abscesses as adequately as possible.
This involves placing a transoral-transesophageal

In some patients it may not be possible to close the perfora­tion because of a delay in diagnosis, because the patient is too sick for the thoracotomy, or because sepsis persists after interventional radiological management or dehiscence of a previous closure.
The treatment of choice in these cases is to divide the

esophagostomy and closing the thoracic esophagus as low as possible in the neck. A long length of cervical esophagus is critical in this situation, as it makes subsequent reconstruc­tion easier. The stoma can be tunneled onto the anterior chest wall and matured at an appropriate location. The cardioe­sophageal junction is closed with a stapling device via laparo­tomy or laparoscopy. This effectively isolates the perforated segment and stops mediastinal and pleural soiling.
to re-establish continuity of the gastrointestinal tract. This is best accomplished 2–3 months later via a total esophagec­tomy by the transhiatal approach and a gastroesophageal anastomosis at the neck. Not unexpectedly, this therapy is associated with a high mortality and significant morbidity.
amenable to primary repair is the insertion of a T-tube. The T- tube is inserted into the esophagus and an appropriate sized cut chest drain, to ensure that the distal holes have been removed, is inserted into the T-tube. A nasogastric tube is passed through the T-tube into the stomach, securing it into place. In this manner, the esophagus is drained and a con­trolled esophocutaneous fistula is created. Although this ther­apy has been used successfully by a number of surgeons, it is not recommended as a routine measure and should only be utilized when the esophagus cannot be reconstructed or closed in a poor risk patient.

Cervical esophageal perforation
Surgical access to the cervical esophagus has been described in a previous section. A similar approach to thoracic esophageal injury is undertaken, including debridement of muscular tissue to identify the mucosal rent and closure in two layers. The repair may be buttressed with strap muscle, but this aspect is less critical in the neck. In fact, many authors advocate simple drainage of cervical esophageal perforations because of the tendency of these injuries to heal without direct suture repair. Adequate drainage can be provided with either closed suction drains or Penrose drains. Debridement of the mediastinal space through a right thoracotomy should be considered if there is significant undrained abscess on CT scan.
POSTOPERATIVE CARE
The patient is intubated for the first 12–24 hours. Good ven­tilation and full lung expansion are essential to prevent atelectasis, pneumonia and to allow the decorticated lung to expand. Also, if the endotracheal tube is removed at the end of the operation, not uncommonly emergency reintubation is necessary. Forceful mask ventilation before emergency re­intubation increases esophageal pressure and may lead to dehiscence of the suture lines. These patients need intensive care during the first few days. The nasogastric tube must be carefully cared for and routinely flushed, as draining the stomach and esophagus is imperative. To decrease gastric acid secretion H2-receptor antagonists are administered. The apical chest tube is removed as soon as good lung expansion is achieved and no evidence of air leaks is seen (usually 2 days after surgery).
Antibiotics and antifungals are continued for 7–10 days, depending on the degree of contamination: in patients with positive results on preoperative blood cultures, antibiotics should be continued for 14 days. Enteral feeds using the feed­ing jejunostomy are started 48 hrs after surgery. If no feeding tube is inserted total parenteral nutrition is administered for the first 8–10 days.
Eight or nine days after surgery, a barium swallow exami­nation should be performed (water-soluble material should be used if there is any suspicion of dehiscence). If this study demonstrates no extravasation, the angled chest tube is removed, and the patient is started immediately on a mechanically soft diet. Patients are discharged home as soon as they can eat and have no evidence of residual infection. If dehiscence is noted and it is contained and asymptomatic, they are kept on enteral or parenteral nutrition for an addi­tional 10 days and the study is then repeated. If symptoms of abscess are present, treatment should be the same as if a delayed perforation is discovered.
Late-diagnosed perforation
Management of the tubes is very important to the success of the procedure to treat late-diagnosed perforation. The tube placement should be inspected periodically (every 2–3 days or more frequently if there is evidence of infection) and cavity size measured by fistulography. The tubes are advanced back into the esophageal lumen as soon as the cav­ity becomes smaller to allow for more rapid closure of the perforation.

Open antireflux operations through a left thoracic approach
ANDRÉ DURANCEAU MD
Professor of Surgery, Chair, Division of Thoracic Surgery, Centre hospitalier de l’Université de Montréal, Montréal, Québec, Canada
HISTORY
Hiatal hernia and its symptoms became recognized during the initial half of the twentieth century. The deranged anatomy of the hiatus with protrusion of the stomach into the chest influenced surgeons to treat this condition and its asso­ciated reflux by restoration of the normal anatomy of the gas­tro-esophageal junction by operative techniques as proposed by Harrington, Sweet, Lertat, Jacob and Allison. Allison, however, documented that in a 20-year assessment of the patients he had treated, 49% showed an anatomical recur­rence. Allison recognized that the reflux of gastric contents into the esophagus was responsible for the symptoms and he proposed the term reflux esophagitis. Woodward and Pope documented that approximately 50% of patients with an anatomical repair had pH documentation reflux after their operation.
Development of more effective antireflux operations were reported mainly during the 1960s and 1970s, and associated with the parallel development of more objective methods to document reflux disease and its complications. The Belsey technique, the Nissen total fundoplication, and the Hill oper­ation were assessed with their respective approach, their respective morbidity and recovery. Collis proposed an esophageal lengthening operation for reflux associated with a shortened esophagus consequent to mucosal damage and peri-esophagitis. This elongation procedure was subse­quently coupled to a partial or a total fundoplication with excellent long-term results.
Standard antireflux repairs and modified repairs lengthen­ing the esophagus with an added partial or total fundoplica­tion have now been described using minimally invasive techniques. The long-term results and the durability of these
procedures in relation to the level of reflux and the inflam­matory change encountered are awaited.
The aim of this chapter is to describe the detailed tech­niques of selected antireflux repairs when they are performed through the chest.
PRINCIPLES AND JUSTIFICATION
The basic principles of surgical reconstruction of the esopha­gogastric junction to insure competency of the cardia against gastroesophageal reflux have been well described and apply to all types of antireflux repairs:
1 The operation should restore the deficient lower
esophageal sphincter to physiological levels (gradient of 15–20 mmHg above resting intragastric pressure).
2 Adequate length of the distal esophagus, including the
lower esophageal sphincter pressure zone, should be reduced to an intra-abdominal position, to be exposed to positive intra-abdominal pressure.
3 The reconstructed cardia should not create a resistance
that will exceed the propulsive force of the esophagus.
4 The operation should be made without tension, and
ensure that the repair will not migrate into the medi­astinum.
5 If the esophagus is shortened, either by inflammation
within its wall from long-term reflux or by peri-esophagi­tis encountered at surgery, an elongation gastroplasty with an added partial or total fundoplication should be con­structed. A repair which has placed the oesophagogastric junction without tension to the infra-diaphragmatic posi­tion, associated with a partial or total fundoplication, is offered as the ideal treatment.

PREOPERATIVE ASSESSMENT
Symptoms usually bring the patient for investigation. These symptoms are not reliable indicators of the presence of reflux disease, the degree of esophageal damage, or provide an indication for surgery.
Radiological assessment aims to document the anatomy of the esophagus and stomach and to classify a hiatus hernia when present. Visual demonstration of reflux on radiology is a poor indicator of endoscopically proven esophagitis.
Objectivity in documenting reflux disease in the esophagus requires the use of investigative methods whereby reflux can be quantified.
1 Endoscopy using the Los Angeles classification or the
MUSE classification gives credit to mucosal damage when mucosal breaks are documented.
OPERATION
2 Esophageal biopsies will document unequivocal evidence
of reflux damage when acute epithelial or subepithelial inflammation and/or ulceration are present. Fibrosis in the submucosa, in the muscle or the presence of a colum­nar lined esophagus are signs of more advanced disease.
3 Manometry documents the physiological abnormalities
and is the scientific basis of gastroesophageal reflux disease. An absent lower esophageal sphincter with esophageal con­tractions showing poor strength and deficient or incoor­dated propulsion is highly suggestive of the diagnosis.
4 Long-term recording of an acid refluxate (24-hour pH) or
of a biliary-pancreatic refluxate (Bilitec) are used to docu­ment abnormal levels of reflux exposure.
5 Radionuclide scintigrams are used mostly to assess the
emptying capacity of the esophagus before and after treat­ing esophageal diseases.

With the index finger behind the right crus, all posterior cardial attachments to the diaphragm are divided. Circumferential clearing of the hiatus is completed. The pleura to the right chest is then opened and divided so that the pleura over the right crus is left intact. The entire esophageal diaphragmatic hiatus is well identified with normal peritoneum covering the abdominal surface and normal pleura over the thoracic side. Left and right crura are ready to be reapproximated by wide, tension free 1-0 silk sutures.

easily opened anteriorly. In this situation, the fundus and greater curvature are easily identified, and the short gastric vessels are dissected free and ligated. More than 50% of patients with severe complications of idiopathic reflux disease (i.e. esophageal stricture or Barrett’s esophagus) actually reveal no evidence of a hiatal hernia. In such a situation, two techniques allow access to dissection of the greater curvature. The first technique opens the retrogastric cavity behind the esophagogastric junction and left crus. Progressive freeing of the stomach is then accomplished by ligation of the short gas­tric vessels. The second approach creates a lateral opening in the diaphragm, approximately 2–3 cm from the muscular insertion on the chest wall. A GIA stapler is used to create a 6­to 8-cm-long diaphragmatic division. Thus exposed, the short gastric vessels are ligated under direct vision, and the entire greater curvature is freed. With two or three fingers positioned through the abdominal hiatus, the phrenoe­sophageal ligament is put under tension and divided around the limits of the hiatus. The anterior and posterior aspects of the lesser curvature are easily identified and dissected using this approach.

curvature are dissected as for a highly selective vagotomy. The fat pad of the esophagogastric junction is resected, the ante­rior and posterior vagi are dissected free from the stomach wall and pushed away to allow the creation of the gastro­plasty, and 6 to 7 cm of lesser curvature is denuded from the surrounding tissue. Closure of the hiatus behind the esopha­gus is accomplished at this point. These sutures cannot be easily placed once the esophagogastric junction repair is com­pleted. The right crus is grasped with a small Duval clamp, holding the crus with the peritoneum under and the pleura above. This maneuver creates an eversion of the right crus toward the chest, allowing an excellent visualization of the inferior vena cava. The left crus is seized in the same way with a second clamp. 1-0 silk sutures are initially passed posteri­orly with bites taking all the tissue layers, including the trans­versalis fascia and the fibrous portion of the crus. A distance of 0.5–1 cm is left between each suture, and when the last suture is installed, easy passage should remain for the index finger between the esophageal wall containing the number 50 bougie and the last suture reapproximating the crura.
