Introduction

Esophageal injury (EI) is a rare just challenging clinical finding in the setting of trauma. Esophageal injuries/perforations are transmural disruptions of the esophagus that subsequently lead to leakage of intraluminal contents into the surrounding mediastinum. This causes local inflammation, systemic inflammatory response, and eventually the development of sepsis that results in significant morbidity and bloodshed. Esophageal injuries can be iatrogenic or traumatic. Examples of iatrogenic mechanisms include endoscopic examinations, nasoenteric tube placement, and surgical procedures. Traumatic mechanisms may be either edgeless (e.yard., motor-vehicle crash) or penetrating (e.g., gunshot or stab wounds). Other miscellaneous mechanisms include foreign torso ingestion, spontaneous rupture (due east.thou., Boerhaave syndrome), and ingestion of acrid/caustic substances. Overall, the almost common mechanism of EI is iatrogenic (upper endoscopy), and patients who are at highest risk for iatrogenic perforations besides tend to have multiple comorbid conditions.[1][two][3][four][5]

Etiology

The esophagus is a muscular conduit, approximately 25 cm long, extending from the lower end of cricoid to the stomach. In the neck, the esophagus originates at the level of the sixth cervical vertebral body. The esophagus then descends anterior to the vertebral column through the superior and posterior mediastinum. Information technology terminates at the cardia, respective to the level of 11th-twelfth thoracic vertebrae. The esophagus has four layers: the mucosa, submucosa, muscularis propria, and adventitia. The muscularis propria is critical to esophageal structure and function. It is composed of ii layers of muscle fibers: The inner (or round) layer and the outer (or longitudinal) layer.

The esophagus is divided into three main anatomical regions: cervical, thoracic, and intra-abdominal esophagus. The corresponding arterial supplies of the esophagus are as follows: inferior thyroid artery, a co-operative of the thyrocervical trunk, supplies the cervical esophagus; branches of the thoracic aorta and bronchial arteries supply the thoracic portion, and the left gastric/inferior phrenic arteries supply the the intestinal esophagus. In terms of venous drainage, the inferior thyroid vein drains the cervical esophagus; the azygous, hemizygous and bronchial veins bleed the thoracic esophagus; and the coronary veins drain the abdominal esophagus.

The upper one-third of the esophagus is nether voluntary control whereas the mid- and distal thirds are under involuntary control. Considering of other nearby anatomic structures, these three singled-out esophageal regions tend to have dissimilar injury patterns, mechanisms, and presentations. Diagnostic and therapeutic approaches vary based on the anatomic region involved. Esophageal injuries are graded based on the American Association for the Surgery of Trauma (AAST) classification, equally follows:

Grade I - Contusion/hematoma, fractional thickness tear
Grade II - Laceration less than 50%
Course Iii - Laceration greater than 50%
Course IV - Less than 2cm disruption of tissue or vasculature
Grade V - Greater than 2cm disruption of tissue or vasculature

Injuries can occur along the entire form of the esophagus. The preferred arroyo to abdominal perforations is a surgical repair. For many thoracic and cervical perforations, not-operative primary direction is acceptable, with surgery being the second-line therapeutic option. The approach was chosen oftentimes depends on the patient'southward clinical presentation and the presence (or absence) of associated injuries to nearby anatomic structures. The cervical esophagus is surrounded past the trachea anteriorly, the spine posteriorly, and the carotid sheath on both sides. Morbidity and mortality of penetrating trauma to the cervical esophagus are closely related to associated injuries to nearby vital structures. In the normal esophagus, the greatest at-risk location for iatrogenic instrumentation injury is the cervical esophagus effectually the region bounded by the inferior pharyngeal constrictor and the cricopharyngeus muscle. Cervical esophageal injuries are the almost common overall and carry the everyman bloodshed due to significant advances in both operative and non-operative management. Thoracic esophageal injuries occur less ordinarily but are associated with the highest morbidity and bloodshed, primarily considering of the proximity of the thoracic esophagus to other vital structures and the take a chance of astringent mediastinal sepsis. The abdominal esophagus is the to the lowest degree commonly injured, with intermediate morbidity and mortality. The lack of the serosal layer, combined with a relatively poor claret supply, combine to increase the overall risk of subsequent complications following injury.[6][7][8][ix][10]

Epidemiology

Overall traumatic esophageal injuries (EI) are rare. Even amid big trauma centers, the typical incidence of EI may be every bit low as 1 to 2 cases per calendar month. Penetrating EI is more common than blunt EI, with a corresponding ratio of approximately 10-to-one. Among penetrating injuries, the most common etiologies in the United States are gunshot wounds (nigh 75%) and stab wounds (most 15%). Many penetrating EI'southward are associated with damage to nearby structures, including neighboring mediastinal organs (e.thou., trachea, centre, lungs). Although uncommon, combined esophageal and tracheal perforations can exist life-threatening. Mortality is extremely high if bang-up vessels are likewise injured. Penetrating trauma to the esophageal hiatus may be associated with potential concomitant injuries to other critical structures such as the aorta, centre, liver spleen, colon, pancreas, and tummy.

The morbidity and bloodshed of esophageal injuries are usually determined by a combination of temporal, patient, and injury severity factors. The all-time prognosis is associated with early on injury identification and treatment, minimal or no injuries to surrounding structures and minimal or no contagion, and an otherwise healthy patient with minimal or no co-morbid conditions. The converse is true with each of the factors being at the opposite of its respective spectrum. Traumatic esophageal injuries often nowadays a diagnostic challenge, particularly because of the potential for harm to surrounding tissues and concurrent contamination. Consequently, the trauma surgeon must be aware of the various mechanisms of EI, employ a high index of clinical suspicion, and act in a timely manner when an injury is suspected.

Pathophysiology

In absolute terms, the almost common EIs are iatrogenic. Ordinarily associated medical conditions include esophageal strictures and achalasia. Iatrogenic EIs can also outcome from intraoperative injury to the esophagus (e.g., during thoracotomy or neck exploration). In approximately 15% of non-traumatic EIs, the cause is a spontaneous rupture, not otherwise associated with whatsoever pre-existing condition. Some causes include forceful vomiting, retching, or increasing in intra-abdominal force per unit area as seen in Boerhaave syndrome.

Non-iatrogenic, traumatic EI patterns vary depending on mechanistic considerations. In this broad group of EIs, penetrating mechanisms predominate. Both stab and gunshot wounds can be problematic because the associated tissue harm may non exist immediately apparent, resulting in diagnostic (and therapeutic) delays. Injury patterns and modalities can vary across unlike geographic areas. For example, gunshot wounds are more than mutual in the United States while stab wounds tend to exist more prevalent in other countries. Penetrating cervical EI is present in less than 1% of all penetrating traumas but has been identified in 5% to 12% of all penetrating cervix injuries. Penetrating thoracic EIs accept been reported to occur in less than 1% of all penetrating thoracic wounds.

Depending on projectile velocity and other characteristics, gunshot wounds tin can cause meaning amounts of shearing, stretch, and blast injury to surrounding tissues. The associated tissue ischemia and full-thickness necrosis may evolve over time, contributing to either a missed diagnosis or delayed presentation, both of which tin can substantially increment morbidity and mortality. Stab wounds generally cause less injury to surrounding tissues but can difficult to visualize if minimal/focal in character. The increasing availability of advanced imaging for trajectory decision, especially for gunshot wounds, is of import in the assessment, diagnosis, and operative planning for EI. This may not be true for stab wounds, mainly to the lesser extent of tissue injury.

Edgeless EIs tend to affect the abdominal/distal esophagus and are commonly associated with motor-vehicle crashes. The pathophysiologic mechanism is due to the sudden application of a blunt forcefulness to the abdomen, commonly with a total stomach. This so leads to the sudden stretching of the gastroesophageal junction, tissue stretching confronting the hiatal crura, and the presence of shear forces that results in the violent of the esophageal wall. The lack of an esophageal serosal layer further exacerbates the injury potential and the risk of perforation. Finally, EIs tin result secondarily as a result of other nearby anatomic structures either eroding into or puncturing the esophagus. For case, vertebral injuries associated with bony fragmentation tin can injure the esophagus, particularly in the mid-cervical and upper thoracic locations, and in the presence of osteophytes. Mediastinal abscesses and hematomas may also cause external compression of the esophagus and resultant symptoms and/or secondary injury.

Because the esophagus can exist considered to be in an anatomically "protected" mediastinal location, it is inherently surrounded by a highly crowded number of other, often critical anatomic structures. Consequently, many traumatic EI'due south are associated with other, potentially serious injuries to surrounding tissues. This is why some traumatologists consider the presence of EI to be a "marker" for other associated injuries. In fact, nearly nine out of 10 patients with penetrating esophageal trauma had major associated findings, including tracheal, vascular, pulmonary, diaphragmatic and spinal injuries.[11][12][13]

History and Physical

A detailed and thorough history and physical examination, with the concurrent identification of pertinent clinical hazard factors, is required for all patients with a suspected esophageal injury. Appropriate imaging is an essential part of EI management. Pain associated with EI tends to be very acute, with chest pain beingness the master symptom in 70% of patients with intrathoracic esophageal perforation. The hurting may radiate to the back or left shoulder, depending on injury location and whatever associated tissue harm. Vomiting and dyspnea may be present in nigh 25% of patients, although this may increment with diagnostic and/or therapeutic delays. Although appreciated in only about 1 out of 7 cases, Mackler'southward Triad (e.g., subcutaneous emphysema, chest pain, and airsickness) is considered to be pathognomonic for esophageal perforation. The Hamman sign, a systolic "crunching" or "rasping" sound, synchronous with the heartbeat, and heard over the precordium, is found in up to one-half of EI cases.

A thorough history and physical examination enhance the clinician's understanding of the location and severity of EI. This and then helps prevent clinical delays, in addition to better guiding the apply of diagnostic imaging. Cervical esophageal injury, for case, may exist associated with dysphonia, hoarseness, cervical dysphagia, and subcutaneous emphysema. Associated imaging workup may then be tailored specifically to these clinical findings. In contrast, perforation at the gastroesophageal junction will most probable nowadays with astute abdominal pain, thus prompting an imaging investigation focused on the identification of peritoneal contagion source. Finally, the thoracic esophageal perforation may manifest either with mediastinal or pleural findings/complaints. Trauma victims suspected to have EI should prompt special attention if they develop a temperature greater than 38.five C, tachycardia, or auscultation of crepitus on concrete examination. This is particularly important given that clinical decline toward septic shock tin be rapid following the initial period with relatively few signs and/or symptoms.

Although specific diagnostic and radiographic findings are beyond the scope of this word, a simple chest 10-ray study will demonstrate evidence of perforation in as many as 90% of cases. Despite that, the finding of subcutaneous emphysema requires approximately ane hour to develop, and the findings of mediastinal widening and pleural effusion(southward) may take up to several hours. Consequently, it is important to reevaluate patients whose initial workup was negative because boosted show of EI may exist detected inside the initial 12 hours mail service-injury.

Evaluation

Contrast-enhanced esophageal imaging provides first-class demarcation of the beefcake and is constructive in detecting perforations. There are different types of contrast media that can be utilized, including water-soluble iodinated high osmolality agents and water-soluble non-ionic agents for preliminary detection of perforation. These are by and large followed by barium sulfate in cases where initial esophagram is negative, only suspicion for the presence of injury remains loftier. It should be noted that because of the possibility of significant esophageal inflammation and edema in the setting of injury, the simulated-negative rate of esophagograms approximates 10%.

Computed tomography (CT) is useful to evaluate nontransmural esophageal perforations not detected on esophagram. CT may help establish the full extent of an injury and guide whatsoever subsequent therapeutic interventions. Some clinical scenarios where CT has high utility include negative early on esophagram with continued loftier clinical suspicion; in patients who are uncooperative, neurologically impaired, and/or critically ill; and cases involving simultaneous vascular and airway injuries. Findings on CT imaging may include gas and fluid gathering around the esophagus; esophageal wall thickening; and radiographic bear witness of inflamed mucosa. Finally, air or air-fluid collection in the mediastinum, pleural effusion(s), pneumocardium and pneumoperitoneum may too exist seen. A chest and upper abdominal CT study with oral contrast are most likely to demonstrate a leak from thoracic or intestinal esophageal perforations.

Flexible esophagoscopy has clinical utility in penetrating trauma because it provides direct visualization of the EI and has a sensitivity of well-nigh 100% with a specificity of about 85%. On the other manus, the role of esophagoscopy in nonpenetrating EIs is inconclusive at best. Because it requires air insufflation, flexible esophagoscopy, is contraindicated with small mucosal or submucosal tears because it may exacerbate the perceived severity of the injury/perforation and thus lead to inappropriate subsequent management. Although generally not indicated every bit the initial diagnostic tool, endoscopy may be justified for use in the setting of continued suspicion of injury despite negative CT scans and esophagograms, besides equally in the setting of the history of GERD or peptic ulcer disease.

Early on diagnosis of esophageal perforation is associated with improved morbidity and mortality. Because EIs are rare, and their initial symptoms tend to be vague, a loftier degree of suspicion, in conjunction with a thorough physical examination and consideration of injury mechanism in the context of pertinent beefcake, may help optimize the direction of EIs.[xiv][15]

Handling / Management

Given their relative rarity, clinical direction of EIs has primarily been extrapolated from accumulated clinical cases and serial, many of which besides discuss non-trauma etiologies of esophageal injury/perforation. Consequently, the following direction strategies commonly practical to esophageal perforation are being generalized to include both penetrating and blunt traumatic EI. Every bit previously stated, the location of injury will play an of import part in the treatment of the EIs, with the focus of this review on thoracic EIs.

In full general, earlier and more prompt diagnosis and management of EIs results in meliorate patient outcomes. The high run a risk of mediastinitis leading to severe systemic sepsis/septic shock, impaired future healing, and disruption of the surgical plan(south) underscores the importance of early on and proper direction. The lack of a serosal layer makes any esophageal repairs far more tenuous than repairs of other portions of the gastrointestinal tract. Definitive closure and drainage are best carried out as before long as possible, although exceptions to these rules do exist. On rare occasions, other life-threatening injuries and/or competing pressing medical conditions may take precedence over the immediate management if EI. In such cases, prioritization of which injury/condition should exist approached first must consider the overall risk-benefit equation specific to a particular clinical scenario.

Not-Operative Management

Non-operative management of EI may be indicated in patients who accept contained leaks, are hemodynamically stable with few signs/symptoms, or those who are moribund and unlikely to survive a major operation. Many patients within this grouping may have had a pregnant filibuster in diagnosis due to a mild clinical presentation. Others may have been institute to have a major injury subsequently surviving the initial sepsis and mediastinitis. Assuming that diagnosis has non been missed and that the patient genuinely has a "contained" esophageal injury, the following criteria may warrant non-operative management (all 3 criteria required): (1) contained leak (2) mild symptoms, and (3) minimal evidence of clinical sepsis. A contained leak is all-time described as extravasation of contrast on esophagram, but the contrast "loops back in" afterward initially extravasating from the esophagus. This is ordinarily a pocket-sized area non associated with a continuing fluid drove, mediastinal inflammation, or pleural effusion. An esophagram tin be repeated within several days to document the resolution of the leak before starting an enteral diet. Patients who are non ideal candidates for operative intervention because of astringent sepsis or pulmonary compromise should undergo broad chest drainage at the bedside, usually using a greater than i tube thoracostomy.

Operative Management

Although there are no prospective studies defining a "safe window" of time within which diagnostic testing tin be completed before operative intervention, there is general agreement that EI is a surgical emergency, and pre-operative testing must be expedited to facilitate a timely repair. The severity of concomitant injuries often necessitates a filibuster of esophageal repair. Literature supports the notion that the degree of inflammation in surrounding tissues (every bit opposed to the time initial injury) should guide the selection of master repair versus drainage. It is also known that the degree of soilage correlates with the overall morbidity associated with EI. Surgical repairs can usually exist achieved, even at delayed fourth dimension periods, in patients with minimal soilage at time of the operation. Considering mail service-repair morbidity and mortality are mainly related (and attributed) to anastomotic failures, every single factor should be considered carefully at the time of initial management strategy formulation.

The location of the injury is some other cistron that influences both the surgical arroyo and various surgical repair options. Injuries of the cervical esophagus are best approached from the left neck where the recurrent nerve tin can exist more hands identified and preserved. The incision should be placed at the inductive border of the sternocleidomastoid muscle and carried downward through the soft tissues between the trachea and the carotid sheath. The esophagus can be mobilized using the edgeless technique, with careful attention not to injure either the recurrent nerve or the membranous portion of the trachea. Buttressing flaps are discussed in afterwards paragraphs (see below).

Thoracic esophageal injuries are best approached through a right posterolateral thoracotomy. Appropriate patient positioning is disquisitional to proper surgical visualization and surgical repair optimization. The intercostal muscle bundle is of great importance and must exist preserved when inbound the thoracic cavity. It tin can be extremely valuable as a potential repair-buttressing flap, providing vascular tissue coverage over the esophageal repair.

The distal 3rd of the thoracic esophagus is best accessible via a left postero-lateral thoracotomy or from the abdomen (subsequently accordingly mobilized). Finally, the abdominal portion of the esophagus is all-time accessed past an upper midline laparotomy. This should be carried upwardly to the xiphoid process and downwardly to the level of the bellybutton.

Principal Repair

Chief repair of an IEs requires attention to several important surgical principles. First, anatomic areas directly involved in the injury must exist fully debrided to healthy tissue. Utilise of necrotic or devascularized tissue will endanger the integrity of the repair. EIs tend to be most all-encompassing at the level of the mucosa. Consequently, simply identifying and repairing the muscular portion of the injury will probable effect in an incomplete closure of the mucosal defect. The muscular defect should be carefully extended until the ends of the mucosal injury are identified.

Second, EI repair must be tension free, and mobilization of the esophagus should exist minimized because its claret supply is segmental. Overzealous mobilization tin can render the anastomosis ischemic and upshot in a postoperative leak. To assistance strengthen the integrity of the repair, the esophagus should be reapproximated in two-layers, with an inner, running, absorbable suture and an outer, interrupted, non-absorbable suture. Stapled mucosal anastomosis likewise can be performed, followed by suture approximation of the outer esophageal layer.

3rd, repairs should be buttressed with local tissue and muscle flaps, especially if repair is delayed (e.g., greater than eight-12 hours from injury) or if there is another nearby injury or next suture line. For case, injury to both the esophagus and trachea with parallel suture lines should be separated by a tissue flap to tracheoesophageal preclude fistula formation. Muscle flaps also meliorate the vascular supply in the setting of active contagion. The selection of tissue flap is dictated past the relative location of the injury and the flap's anatomic origin (e.g., vascular supply). Commonly used flap materials include latissimus dorsi, serratus anterior, or intercostal muscles. Pericardium or pleura are secondary choices because they are more than frail and comparatively less vascular. In the breast, the intercostal muscle provides the simplest and near reliable tissue flap. Care must be taken when making the thoracotomy incision to preserve this of import muscular complex. Other flap options in the chest include the latissimus dorsi, the rhomboid, and the diaphragm. In the abdomen, a Thal patch (e.g., gastric fundus) or various types of fundoplications can exist performed. For cervical EIs, the sternocleidomastoid musculus tin be used as a barrier between adjacent structures or to reinforce the repair. Due to its arable blood supply and location, the sternocleidomastoid is very reliable as a tissue flap. Wrapping the esophagus with the platysma muscle has also been described.

Fourth, appropriate drainage should back-trail all esophageal repairs. This reduces the severity of systemic reaction and sepsis in the event of an anastomotic breakup. It also serves as a diagnostic "early alarm system," especially when one considers that an undrained mediastinal collection tin lead to severe sepsis and significantly elevates patient mortality. When used appropriately and performed in a timely fashion, primary repair of EIs is the preferred option, with low morbidity and mortality.

Wide Breast Drainage

Wide chest drainage lone tin be utilized as an option to control contagion in patients who are non candidates for primary repair or surgical diversion. This may be due to other competing clinical priorities, co-morbid conditions, or cases where tissue inflammation and soilage preclude injury repair. Normally, broad drainage can be performed in the setting of shut observation, in the intensive care unit. In many such cases, patients may be unstable to withstand a major operation. At the same time, operative placement of drains tends to be more effective. Beyond initial direction, if wide drainage becomes the "primary" direction, information technology may exist combined with esophageal diversion and/or exclusion (meet below). Because of the inherent patient choice bias, wide drainage alone is associated with exceedingly high mortality.

Esophageal Diversion & Exclusion

Esophageal diversion and exclusion facilitate a decreased local flow of oral secretions and reflux of gastric contents at the site of EI. A diverting cervical esophagostomy should exist performed in cases where primary repair is not a viable option and wide drainage is therefore chosen as the treatment approach. Esophageal exclusion (diversion with the closure of the gastro-esophageal junction) can exist considered for all-encompassing EIs (or those diagnosed with a delay), especially in the setting of significant tissue contamination and swelling. The involved anatomic locations are most often in the mid-to-distal esophagus.

Patients with a delayed diagnosis of EI can present with marked inflammation of the upper mediastinum that tin can preclude esophageal mobilization and creation of a proximal loop esophagostomy. In such cases, an end cervical esophagostomy can be created, clearly not a preferred approach that is acceptable simply every bit a temporizing measure for several days while the mediastinal sepsis resolves. If the diverted esophagus is as well temporarily excluded, either with absorbable sutures or a stapling device, recanalization of the diverted portion takes identify, unremarkably in as piffling as 2 weeks. This may present clinically equally renewed mediastinal contamination in an otherwise recovering patient. Once the esophageal injury seals off from the pleural spaces and mediastinum, careful attention must be given for the development of the so-chosen "blind loop" syndrome. Bacterial stasis and overgrowth within the excluded esophagus can result in sepsis. In such cases, CT imaging may bear witness a grossly dilated and enhancing esophagus. Later on confirming the diagnosis, the "blind loop" syndrome is treated with appropriate drainage procedure(s), unremarkably adamant on case-by-case basis.

T-Tube Diversion

T-Tube diversion of the esophagus tin can exist used for smaller, usually distal injuries in patients who are not candidates for main repair and where formal diversion and exclusion may non be required. From a surgical standpoint, the T-tube is placed directly through the injury into the site of EI and kept on constant suction to encourage the formation of a controlled fistula. The tube is kept in place for several weeks to let a tract to form. This approach is especially useful for small injuries virtually the gastro-esophageal junction. Placement of large bore mediastinal and pleural tubes should accompany the T-tube. Once stable, the patient will need a gastrostomy tube for decompression and a jejunostomy tube for feeding.

Esophagectomy

Esophagectomy is rarely required equally therapy for EIs merely may be needed if the master repair fails or cannot be performed afterward "impairment control" maneuvers involving diversion and/or exclusion. Limited, retrospective clinical data suggest that esophagectomy may exist the preferred arroyo for patients diagnosed with delayed EIs. These experiences advise an acceptable safety profile of this approach, peculiarly in the absenteeism of any farther interventions. Associated mortality also may be lower than that for non-operative approaches. If esophagectomy is selected every bit the optimal arroyo for a carefully selected patient, it is all-time performed using the Ivor-Lewis technique because the mediastinum is usually too inflamed to facilitate safe of transhiatal approach. Because of the technical complexity of this functioning, particularly in the setting of EI, it should optimally be carried out by experienced thoracic or esophageal surgeon(southward).

The simplest and well-nigh commonly performed repair, characterized by a unmarried anastomosis, is the gastric "pull-up." Because the tum is ordinarily the conduit of option, gastrostomy tubes should not be placed in patients with EIs who require resective managment. When the gastric "pull-up" option is not available, mail service-esophagectomy restoration of luminal continuity tin exist performed using a colonic interposition (usually transverse colon) or a Roux-en-Y jejunal limb. The determination regarding which conduit to utilise depends on any concomitant injuries and the availability of a non-injured, well-perfused conduit. Preferred enteral feeding access is via a surgical jejunostomy tube.

Post-Operative Intendance

Post-operative care involves appropriate monitoring, initially in an ICU setting. Early recognition and treatment of cardiovascular complications and/or sepsis is paramount. Adequate nutritional support too plays an of import role in optimizing clinical outcomes. Total parenteral nutrition or jejunostomy feeding should be started as soon equally possible. Contrast swallow evaluations should take identify 5 to vii days after main esophageal repair if no clinical signs of leakage are nowadays. All drains should be maintained until contrast radiography confirms healing.

Complications of Operative Care

An anastomotic breakdown is unfortunately relatively frequent after EI repairs, primarily due to the multitude of risk factors outlined in previous sections. Depending on the location of EI, these leaks can lead to secondary wound infection, mediastinitis, abscess, empyema, pneumonia, and sepsis. Of all these complications, sepsis carries the highest associated mortality. Thus, the primary goal of postoperative direction should be the prevention of sepsis by maintenance or establishment of wide drainage. Early recognition of sepsis is critical in instances where broad drainage fails to control soilage.

Fistula formation between the repaired esophagus and adjacent structures can occur in the immediate post-operative catamenia or in a delayed fashion. The incidence of such fistulae increases when an adjacent structure also requires a concomitant surgical repair. Cutaneous and vascular fistulas have been described, but the nearly mutual fistula is a tracheal-esophageal fistula. These fistulae usually course at or just higher up the carina, and nowadays with coughing later on nutrient or liquid ingestion and eventually the development of pneumonia. Equally previously discussed, the placement of an interposition vascularized tissue flap may help reduce the incidence of this morbidity. Commonly seen longer-term complications include stricture formation and the development of diverticulum effectually the repair site. Although most anastomotic strictures can exist treated with endoscopic dilations, refractory cases may require esophagectomy. Diverticulum formation has also been noted post repair. Treatment of such diverticula depends on their size, location, and global clinical circumstance/context.

Cervical Esophageal Injury

In most cases, cervical EIs can be managed non-operatively or by elementary retroesophageal drainage, commonly combined withcypher per bone (NPO), antibiotics, and early nutritional support. Provided that any foreign bodies associated with the injury have been removed, such a not-operative approach is by and large sufficient to reach healing of the EI in question. In the continued presence of foreign bodies, surgical removal of the offending object and primary repair seems to be the all-time option. Surgery too may exist required when the non-operative approach fails to result in expected clinical comeback. If other injuries (eastward.grand., vascular or airway trauma) mandate surgical exploration, a primary repair can be constructive in both controlling whatever ongoing contamination and reducing whatsoever associated vascular or airway-related complications. Negative force per unit area wound therapy has too been reported for complicated cases that failed to answer to the aforementioned options.

Esophageal Stenting

In patients with significant comorbid weather, intra-luminal stenting has been described equally a means to prevent intraluminal material from contacting the esophageal wall during the tissue healing process. Although this technology is even so maturing, information technology will likely play a greater role in the future. Equally mentioned briefly in previous sections of this review, esophageal stenting has been used selectively in cases of EI, both primarily and for postoperative anastomotic leaks. Stents have been utilized in the care of thoracic EIs with practiced results, challenging the existing standard of care. In a recent retrospective study, handling of esophageal perforation with stents rather than primary repair was associated with lower costs, fewer ICU days, shorter hospitalizations, quicker resumption of oral intake, and equivalent overall mortality. The timing of stent placement (e.g., less than 24 hours versus greater than 24 hours post-injury) does not seem to impact outcomes.

Among some of the reported advantage of esophageal stenting are (a) the ability to administer oral hydration and nutrition; (b) the possibility of device removal (e.g., reversibility); and (c) rapid elimination of mediastinal, pleural, and peritoneal contamination. In whatever setting esophageal stenting is used, it is important to think that contamination must still be controlled and adequately tuckered. In some cases, a hybrid approach utilizing stenting and thoracoscopic decortication may exist indicated. Finally, esophageal stenting is best utilized in the setting of isolated EI, and the presence of concomitant injuries may preclude its use. Consequently, stenting has been employed for iatrogenic and other non-trauma indications far more frequently than EI resulting from trauma.

Despite its clinical attractiveness and ease of placement, stenting of thoracic EIs has some potential downsides, including patient tolerance issues and the risk of stent migration. For the latter reason, stenting is not being performed for cervical or gastroesophageal junction EIs. Stent migration is a business organization and may lead to further interventions. Migration of the stent is more than likely with nonmetal stents are used.

Differential Diagnosis

Esophageal perforation can often be an obvious diagnosis if the patient presents later a traumatic effect or if symptoms coincide with an esophagogastroduodenoscopy (EGD).

However, if a perforation is missed and then the patient tin can nowadays with chest pain, fever, or signs of systemic infection which can accept a broad differential including, but not limited to:

Myocardial infarction
Mediastinitis
Viral myocarditis
Esophagitis
Pulmonary embolism
Aortic dissection
GERD
Gastritis

Prognosis

Esophageal injuries can consequence from both penetrating and blunt trauma. The need to screen for injury is based on a loftier degree of suspicion. Many patients may exist asymptomatic initially. Imaging using CT scan is helpful to decide the potential for injury, especially in penetrating injury. Further workup should exist timely, as an early diagnosis can assistance forestall further soilage and subsequent morbidity and mortality. Flexible endoscopy and contrast esophagography are complementary and together give the highest diagnostic yield. Primary repair with suture line reinforcement using muscle flaps and wide drainage affords the patient the best consequence. Stent placement in certain conditions can assistance equally a bridge either to surgery or definitive management. Early on enteral nutrition via jejunostomy is preferred. Overall, the morbidity and bloodshed of esophageal trauma are high, and a loftier index of suspicion and aggressive treatment plan are required to optimize event.

Complications

The near feared complication of esophageal perforation is mediastinitis and sepsis which business relationship for most of the morbidity and mortality related to this condition. Patients with undiagnosed esophageal perforations may also suffer from pleural effusions, abscess formation, bleeding, pneumothorax, or other complications involving leakage of air and esophageal contents into the thorax.

Postoperative and Rehabilitation Care

Postoperative and rehabilitative care may vary widely with patients that have a small, contained perforation able to be discharged within the same day as admission whereas patients with large revitalized segments of the esophagus may require extended ICU fourth dimension as well as nutritional support via a feeding tube or parenteral diet.

Consultations

Esophageal perforations tin be a surgical emergency and a full general or thoracic surgeon should be consulted immediately upon diagnosis of this pathology. Depending on the patient's condition at presentation it may as well be reasonable to inform an intensivist ahead of time of the likely need for an ICU bed.

Deterrence and Patient Education

Given that the majority of esophageal perforations are iatrogenic or traumatic in nature deterrence is difficult. Patients undergoing esophagogastroduodenoscopy (EGD) for any reason should exist informed of the potential take a chance for esophageal perforation and the treatment options that would and then get necessary.

Enhancing Healthcare Squad Outcomes

Care of patients with EIs is an interprofessional, usually consisting of multi-specialty teams, including traumatologists/acute care surgeons, thoracic surgeons, otolaryngologists (for upper aerodigestive injuries), gastroenterologists, and intensivists. Mortality rates associated with EI range between 10% to 40% and depend on a variety of factors, including the crusade of the perforation, the presence of whatever underlying (pre-existing) pathology, the location of the perforation, any diagnostic or treatment delay, the method of treatment employed, and the extent of the injury. Comorbid conditions, as well every bit the patient'south functional and nutritional status, also play an important prognostic office. For a patient who survives their EI, loftier levels of morbidity, long hospital and ICU stays have been reported. Subsequent (post-discharge) quality of life can be negatively afflicted by EI. Because esophageal injuries occur infrequently and may produce vague symptoms, diagnostic and therapeutic delays are non uncommon. [xvi]
