Surgical management of penetrating injuries of the esophagus

Although well protected and infrequently injured, penetration of the esophagus has a reported mortality of 10 to 30 per cent. The results of the management of seventy-seven patients with noniatrogenic penetrating injuries of the esophagus were reviewed. The region of esophageal injury was cervical in forty-five patients, intrathoracic in twenty-one patients, and intraabdominal in eleven patients. Gunshot wounds accounted for 75 per cent of the injuries. The overall mortality was 23 per cent. The highest morbidity and mortality was among patients with intrathoracic injuries, due to both difficulty in exposure and complexity of associated injuries. Because of the high incidence of late complications in intrathoracic injuries, cervical diversion and tube gastrostomy or complete esophageal exclusion must be considered early. Fundoplastic procedures were used in four patients with distal esophageal injuries. Although the overall mortality from truncal penetrating wounds has improved in recent years, the mortality from esophageal injuries remains high, reflecting a need for advancement in initial operative management.     

Fifteen years' experience with penetrating trauma to the head and neck in children

To determine the extent and consequences of penetrating trauma to the head and neck in children, as well as the safety and efficacy of selective management of penetrating wounds of the face and neck, we reviewed our experience with these injuries since 1970. During this interval, 45 children aged 2 to 17 years were admitted for treatment of 37 missile wounds (MW) and eight stab wounds (SW). Most patients reached the hospital within 30 minutes of injury. The greatest single number of these injuries were due to accidents; violent crimes accounted for the remainder of injuries in which a motive for attack was known. Craniotomy was performed in neurologically viable patients only; neck exploration was reserved for those patients who presented with profuse hemorrhage, an expanding or pulsatile hematoma, respiratory distress, or violation of the esophagus, trachea, or great vessels seen on fluoroscopy, endoscopy, or angiography. Overall survival was 87% (MW 84%, SW 100%). Three of the nonsurvivors presented in extremis with gunshot (GSW) wounds to the head, and died shortly thereafter, while two who presented with similar injuries survived craniotomy but died subsequently from irreversible brain damage; one presented in shock due to massive hemorrhage (internal jugular vein transection flush with the base of the skull) and exsanguinated during attempted repair. Among the 39 survivors, 15 sustained multiple wounds, but only two presented in shock, due in both instances to tension pneumothorax. Soft tissue injuries of the scalp, face, and neck accounted for 36 of the 39 nonfatal wounds; five of these involved major cervical structures, but only four required immediate exploration.(ABSTRACT TRUNCATED AT 250 WORDS)     

The diagnosis and treatment of injuries of the upper respiratory tract in wounds and traumas of the neck

The authors made an analysis of results of treatment of 339 patients with wounds and closed injuries of the neck. Laryngotracheal injuries were found in 27 (7.9%) patients, in 15 patients the injuries being of combined character. Active surgical strategy including the necessary thorough revision of the penetrating wounds of the neck during operation under general narcosis anesthesia, by instrumental methods of examination. Such strategy allowed timely detection and adequate elimination of injuries of the organs and vessels of the neck and improvement of the results of treatment of such patients.     

The management of penetrating neck injuries

In recent years, there has been a major increase in patients with penetrating injuries to the neck admitted to the Johannesburg Hospital. Pressure on resources led to increasing delays for surgery, and a policy of selective conservatism emerged. In common with other centers, mandatory exploration of all wounds that breach the platysma was found to be no longer necessary as it became clear that many penetrating wounds to the neck were best treated conservatively. A policy of blanket investigation of all nonoperated cases also matured toward selective investigation, directed by careful clinical examination. A retrospective study was made of all patients undergoing exploration for gunshot wounds or stabs to the neck at the Johannesburg Hospital Trauma Unit between 1994 and 1998. An overall mortality rate of 9% was mostly a reflection of severe, associated injuries. The evolution of the nonoperative management of cervical penetrating wounds is a good example of the validity of the concept of "selective conservatism." A distillation of the experience at a busy, urban trauma center is presented, with guidelines to manage these potentially lethal injuries.     

Injuries of cervical great vessels

Results of surgical treatment of 156 patients with cervical vessels injuries over 10-year period were analyzed. The majority of the wounds (82.7%) located in zone II of the neck. There were 143 (91.7%) stab-knife and 12 (7.7%) shotgun wounds. Combination of vascular traumas with injuries of deep cervical structures was in 16 (10%) patients. Detailed physical examination permits to avoid special device examinations before surgery in the majority of cases. When injuries of the esophagus or respiratory tract were suspected, the patients underwent diagnostic esophago- and bronchoscopy before and during surgery. Diagnostic and therapeutic policies in these kinds of injuries are systematized.     

Evaluation and treatment of penetrating cervical injuries.

Because the serious nature of penetrating cervical injuries may not be readily apparent on initial evaluation, and since delay in treatment can result in serious complications, a systematic method of evaluation and routine exploration has been employed in treating these injuries. One hundred eighty-nine patients, 49 with gunshot wounds and 140 with stab wounds, were treated in this series. Arteriography was performed in 62 patients (33%) to detect vascular injuries and to aid in the planning of the operative approach in patients with high or low neck wounds. Arteriography was 98% accurate and changed the operative approach in 29% of the positive studies. Of the 154 explorations 72 were positive (47%). There were no deaths and only four complications in the group with negative explorations. The mortality rate for the series was 2.6%. We believe that angiography in selected patients and routine exploration of wounds penetrating the platysma can minimize morbidity and mortality in these injuries.     

Bleeding control in stab wounds to the great vessels at the neck base

Stab wounds of the neck are a great challenge for every surgeon. Approximately 25% of penetrating neck injuries results in a vascular lesion. Wounds being situated below the cricoid cartilage are associated with the great mortality and morbidity, having a global mortality between 12-20%. 2/3 of the vascular wounds at this level have a tragic end. We are going to present 3 cases of cervical stab wounds in zone 1 of the neck, with vascular lesions, in which we succeeded to control the hemorrhages throw a midline sternotomy combined with different extensions. After this small experience we think that in patients with wounds situated in zone 1 of the neck, who reach the hospital hemodynamically unstable or with active bleeding, urgent midline sternotomy combined with cervicotomy, or section of the clavicle, is the best way to control the hemorrhages. Using blunt digital dissection we can avoid unpleasant situations that can appear using instrumental dissection into the mediastinal hematoma.     

Selective management of penetrating neck injuries based on clinical presentations is safe and practical

Selective management was offered in 57 patients who had penetrating injury to the anterior neck. During the study period, decision making in patient management at our institution depended largely on clinical presentations. Indications for neck explorations were unstable hemodynamics, airway obstruction, active bleeding from the wound, and evidence of aerodigestive tract injuries. Some patients with deep wounds of zone II also underwent neck explorations. Investigations were performed in selected cases. With this selective policy, there were two unnecessary operations among 40 patients (70.2%) who underwent neck exploration. Both of them were operated because of deep wounds of zone II. The remaining 17 patients (29.8%) had uneventful conservative treatment. There was no mortality in this study. The authors concluded that selective management of penetrating neck injuries based on clinical presentations is safe and practical.     

Penetrating wounds of the cervical esophagus

To determine trends in management, twenty-two years' experience with penetrating wounds of the cervical esophagus in thirty-nine patients has been evaluated. There were three deaths, all as a result of delayed operative repair. Experience gained from the earlier years of this study led to a marked reduction in mortality in the later years as a result of an increased index of clinical suspicion, coupled with an aggressive operative approach with primary closure and adequate drainage. A nonoperative approach has been suggested by others for small esophageal perforations after endoscopy and perforation from foreign objects. For penetrating injuries of the esophagus, operation and definitive repair is mandatory.     

Diagnosis and treatment of iatrogenic and criminal injuries of the esophagus

An experience with treatment of iatrogenic and criminal traumas of the esophagus included 57 patients. There were 36 patients with iatrogenic traumas (perforation of the esophagus during diagnostic and curative manipulations and operations on the lungs and esophagus). Different kinds of operations were made depending on the localization of the injury. Three patients of this group died. Criminal traumas of the esophagus (wounds with cold steel) were treated in 21 patients, sutures on the esophagus were put in 19 of them, drainage--in 2 patients. All the patients recovered. Better results of treatment of the penetrating iatrogenic and criminal injuries of the esophagus can be achieved by timely diagnosis and operation using the proper volume and method.     

Management of airway trauma. II: Combined injuries of the trachea and esophagus

Twenty-four consecutive patients with combined injuries of the trachea and esophagus were operated on at the Tulane University Hospital and the Charity Hospital of New Orleans between 1967 and 1983. Only 3 of the injuries resulted from blunt trauma, and 1 of these patients had a total transection of both the trachea and esophagus; the remaining injuries were due to penetrating trauma (20 gunshot wounds; 1 stab wound). The combined lesions involved the cervical region in 20 patients and the thoracic esophagus and trachea or bronchus in 4. All patients underwent bronchoscopy; in recent years all have had esophagoscopy, because our experience indicates that esophagrams, which patients also underwent, have a high rate (12.5%) of false negative results. Operative techniques included a two-layer closure of all esophageal injuries, closure of the trachea with non-absorbable monofilament suture, and transthoracic or cervical drainage. Muscle flaps were used for suture line reinforcement. Associated operative procedures included tracheostomy (5), laparotomy (4), vascular procedures (5), neurologic procedures (2), and closed-tube thoracostomy (6). Five patients (21%) died in the perioperative period, 4 of 20 with combined cervical injuries, and 1 of the 4 with combined thoracic injuries. Deaths resulted from missed injuries to the esophagus (2 patients), a missed tracheal injury (1), associated vascular injury (1), and associated thoracoabdominal injury (1). Two patients experienced cervical esophageal suture line leaks, both of which sealed with conservative therapy. Clinical follow-up showed good results in 90% of the patients who survived.(ABSTRACT TRUNCATED AT 250 WORDS)     

Prospective evaluation of screening multislice helical computed tomographic angiography in the initial evaluation of penetrating neck injuries

BACKGROUND: The optimal management strategy for patients sustaining penetrating neck injury without an urgent indication for operative exploration remains controversial. The objective of this study was to prospectively assess multislice helical computed tomography angiography (MCTA) as a stand alone screening modality for the initial evaluation of hemodynamically stable patients with penetrating neck injuries. Our hypothesis was that MCTA is a sensitive diagnostic screening test that could noninvasively evaluate the vascular and aerodigestive structures of the neck. METHODS: After Institutional Review Board approval, all penetrating neck injuries assessed during a 16-month period were prospectively evaluated at a Level I trauma center. Patients without an indication for urgent neck exploration underwent MCTA screening. MCTA accuracy was tested against an aggregate gold standard of final diagnosis encompassing all imaging, surgical procedures and clinical follow-up obtained. RESULTS: In all, 106 injuries penetrated the platysma; 15 required urgent exploration and 91 underwent MCTA (34 gunshot wounds/57 stab wounds). Nineteen external wounds were in zone 1, 39 were in zone 2, 10 in zone 3, and 23 traversed multiple zones. MCTA was nondiagnostic in 2.2% secondary to artifact from retained missile fragments. Follow-up was achieved in 84.5% of patients for a mean of 33.3 days (range: 2-150). MCTA achieved 100% sensitivity and 93.5% specificity in detecting all vascular and aerodigestive injuries sustained. MCTA correctly identified two tracheal and two carotid artery injuries requiring operative or endovascular repair in asymptomatic patients. No injuries requiring intervention were missed by MCTA. CONCLUSION: In the initial evaluation of stable penetrating neck injuries, MCTA appears to be a sensitive and safe screening modality. Further investigation is warranted.     

The nonoperative management of penetrating internal jugular vein injury

OBJECTIVE: The objective of this study was to review the outcome of nonoperative treatment for penetrating internal jugular vein (IJ) injuries in a continuous series of prospectively identified, hemodynamically stable patients. METHODS: All penetrating neck injuries assessed from February 1, 2004, to August 31, 2004, were prospectively identified. Patients without an indication for urgent neck exploration underwent diagnostic assessment with multislice helical computed tomographic angiography with or without vascular ultrasonography. All IJ injuries with no other indication for surgical exploration were treated nonoperatively. All patients were discharged home and followed up for a minimum of 1 week to document outcomes. RESULTS: From 51 neck injuries penetrating the platysma, 7 required urgent neck exploration, during which 2 IJ injuries were ligated. Forty-four patients underwent multislice helical computed tomographic angiography. Eight IJ injuries (two gunshot wounds and six stab wounds) with no other indication for neck exploration were identified and managed nonoperatively. One external wound was in zone 1, five were in zone 2, one was in zone 3, and one traversed all three zones. The average length of stay was 4.5 days. At follow-up, ranging from 1 week to 5 months, all patients were asymptomatic, and no patient required delayed operation for IJ injury. CONCLUSIONS: In hemodynamically stable patients with no other indication for exploration, the nonoperative management of penetrating jugular vein injuries should be considered as a safe alternative.     

Penetrating neck wounds

A review of 68 cases of penetrating neck wounds from our institution as well as a review of the recent literature dealing with the management of such injuries is presented. The wounding agent was gunshot (38 cases), knife (21), broken glass (3), an ice pick (1) and miscellaneous (5). Presenting findings were hematoma (20 patients), neurologic deficit (13), shock (8), pneumo- or hemothorax (7), subcutaneous emphysema (7), bruit (2) and no major findings in 24 patients.Of the 68 patients, 19 were managed nonoperatively with only one complication. The remainder of the group underwent exploration, with negative results in 26 patients or 67 percent. Positive findings at operation included major vascular injuries in nine patients, esophageal injuries in six and tracheal injury in three.We conclude from our experience and a review of the literature that mandatory exploration is not required in all penetrating neck injuries. Current indications for surgery at our institution include all gunshot wounds and other wounds associated with one or more of the following: shock, significant hematoma, active bleeding, hemoptysis, hematemesis or subcutaneous emphysema. Close observation for 48 hours is indispensible in all patients managed nonoperatively. Ancillary procedures such as arteriography, esophagoscopy, barium swallow and bronchoscopy are valuable diagnostic procedures in selected cases. Careful examination of the pharynx, esophagus and trachea should be carried out in all observed patients.     

Cervical spine osteomyelitis with delayed onset tetraparesis after penetrating wounds of the neck. A report of 2 cases

Two adult patients developed cervical vertebral osteomyelitis after earlier sustaining penetrating wounds of the neck. The initial injuries were not explored surgically. Both patients were subsequently shown to have perforation of the oesophagus. In the first case the perforation was overlooked, with a resultant oesophageal fistula, while in the second case the perforation was anticipated and a fistula prevented. Pre-operative investigation of such cases by oesophagogram and endoscopy, and careful surgical observation for a perforation can prevent the complications of an oesophageal fistula.     

Penetrating injuries of the neck: use of helical computed tomographic angiography

The diagnostic evaluation of stable patients with penetrating trauma to the neck remains controversial. Conventional angiography has traditionally been considered the gold standard for evaluation of vascular injuries. The use of angiography for stable patients with penetrating neck trauma has been questioned because of its invasive nature and reported low yield. In recent years, there has been a renewed interest in the use of noninvasive techniques such as helical computed tomographic (CT) angiography for the evaluation of these patients. Helical CT angiography, a low-risk, rapid, accurate, noninvasive, reproducible technique, is less expensive than conventional angiography. Helical CT angiography also can provide information about potential lesions of associated vital structures such as the cervical spine and the aerodigestive tract. This review evaluates the authors' current protocol for penetrating neck wounds and identifies indications for helical CT angiography.     

Mandatory vs selective exploration for penetrating neck trauma. A prospective assessment

To determine the optimal management of patients with penetrating wounds to zone II of the neck, we performed a prospective evaluation of 120 consecutive patients with such injuries, correlating the results of clinical and diagnostic examinations with operative findings. Seven patients presenting with life-threatening hemorrhage from the neck wound were operated on immediately; the remaining 113 patients underwent arteriography, laryngotracheoscopy, esophagoscopy, and esophagography, followed by neck exploration. Forty-eight major injuries were identified in 35 neck explorations. Five patients were identified with clinical and diagnostic findings that were considered normal preoperatively; however, at operation six major injuries were found in these patients. This study indicates that potentially lethal injuries to major vascular and visceral structures in the neck may go undetected if selective exploration criteria are used in the decision to explore penetrating wounds to zone II of the neck.     

Selective management of gunshot wounds to the neck. Report of a series and review of the literature.

Thirty-two patients with gunshot wounds to the neck, 13 with multiple pellet injuries and 19 with single missile injuries, were managed selectively. Although 3 of the 32 patients died in the hospital, no death was attributable to the neck injury. This experience and a review of the literature support the concept of selective management of penetrating neck injuries with intervention based on specific indications.     

Current concepts in the management of penetrating neck trauma.

Six hundred thirty-two cases of penetrating wounds of the neck were analyzed in this study in order to re-evaluate our current concepts in the management of these injuries. There were 35 deaths in this series, an overall mortality rate of 5.5%. However, in the last 10 years there were only 13 deaths among 407 patients, a 3.2% mortality rate. Early exploration was performed in 507 patients, and 125 patients were observed. Explorations revealed a total of 625 separate injuries. In 142 explorations, no injury was found. There was no mortality or significant morbidity in these patients with negative explorations. Patients who presented with obvious vascular or visceral injury were immediately explored. Those wounds without obvious injury were either explored or observed, depending on the index of clinical suspicion based on awareness of the innocuous presentation and difficulty in diagnosing esophageal injuries. The mortality rate is a function of multiple factors. Its decrease over the past 25 years is related to many improvements in our health care system. Our own decrease in mortality rate can be attributed in part to decreased transportation time resulting in less blood loss. A greater awareness of esophageal injuries was another factor. No conclusions are possible as to the feasibility of conservative management based upon the mortality rates alone; however, on examination of our experiences with penetrating wounds of the neck, it appears that a significant number of patients when carefully selected by trained personnel can be safely managed with observation.     

Limited role of arteriography in penetrating neck trauma

Of the patients with penetrating neck wounds treated between 1979 and 1986, 61 patients with 65 injuries had arteriography during their evaluation. Twenty-seven patients had stab wounds and 34 had gunshot wounds, with a relatively equal distribution between the zones of injury. Fifty-seven arteriograms were normal and six were abnormal. Of the six arteriographic defects, three were thought to be spurious on subsequent review, two were clinically insignificant, and one required surgery. No significant arterial injuries were identified by arteriography in the absence of suggestive physical findings. No major arterial injuries were discovered during neck surgery that were missed preoperatively. Neither abnormal nor normal angiograms significantly altered the course of management, including the approach to neck exploration. These data suggest that arteriography for penetrating neck trauma is usually unnecessary for observation of patients in stable condition without suggestive physical findings. Thorough neck exploration with dissection of the carotid sheath in patients with physical diagnostic criteria for surgery eliminates the need for angiography in most cases and avoids the consequences of a possible false-negative study.
