Acute penetrating neck trauma presenting with laryngotracheal injury

Laryngotracheal injuries are serious complications in the case of penatrating neck trauma which may not commonly in Japan. In the last several decades, many authors have discussed method for accurate evaluation and immediate airway management for patient with laryngotracheal injury. But, standardization of the treatment is still controversial about mandatory exploration or selective exploration. We report 4 cases with fresh laryngotracheal injury due to penetrating neck trauma including 3 suicide attempt patients. In these cases, laryngotracheoplasty used by absorbable material was performed within 8 hours after trauma. Two cases of suicide attempt patients underwent tracheostomy at the lower level of the laryngotracheal injury. After these treatment, fiberoptic bronchoscopy was performed to evaluate the airway for 3 cases except 1 who was dead because of hemorrhagic shock on arrival. In 2 cases, the suture filament existed in the lumen of the larynx and trachea, there were no major granulation in the site of repairment and no infection. Three cases were extubated successfully and discharged without major airway problem. Two cases have psychiatric disease such as depression, so we must consider their psychiatric background in the future. In conclusion, penetrating laryngotracheal trauma, we should consider that serious airway injury may be hidden under the superficial small wounds. Also, rapid local wound exploration and laryngotracheoplasty is important for life-saving, and fiberoptic bronchoscopy is effective to prevent early respiratory complications and has value in the evaluation.     

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.     

Carotid-esophageal fistula following a penetrating neck injury: case report

Carotid arterial injuries frequently are associated with injuries to adjacent structure of the neck, particularly the esophagus and trachea. Complications from these repairs are common and fistula formation is herein described between the carotid artery and esophageal repair.     

The morbidity of penetrating colon injury

The purpose of this study is to define the current morbidity and mortality associated with penetrating colon injury and to determine the impact of management strategy on outcome. METHODS: A retrospective review was performed of all penetrating colon injuries managed at a level I trauma center (1990-2000), n=186. Stepwise logistic regression was used to determine the independent predictors for colostomy and morbidity following colon injury. RESULTS: Fifty-three percent of the patients were managed with primary repair or anastomosis while 47% received a colostomy. Independent predictors of colostomy included gunshot wound (GSW), degree of peritoneal contamination, and location of injury. The complication rate for patients requiring a colostomy was 57% versus 42% for the primary repair group, P=0.01. When adjusted for injury severity and hypotension, the presence of a colostomy was not associated with a significant increase in the complication rate (OR 1.7, 95% CI: 0.9-3.25). Independent predictors for the development of intra-abdominal abscess were hypotension on admission (OR 2.4, 95% CI: 1.1-5.8) and penetrating abdominal trauma index (PATI) score >25 (OR 4.2, 95% CI: 2.0-8.9). The complication rate for colostomy takedown was 17%. CONCLUSION: Penetrating colon injury carries a high rate of infectious morbidity. The development of infectious complications is related to the injury severity and haemodynamic status of the patient, not the type of operation performed.     

The role of angiography in penetrating neck trauma

Seventy-two consecutive patients who underwent neck arteriography were reviewed to assess recent suggestions that angiography is not indicated in asymptomatic patients with penetrating neck trauma. Proximity to major neck vessels without signs or symptoms of vascular trauma was the reason for angiography in ten of 26 patients with proven arterial injuries. Physical examination had a specificity of 80% and a sensitivity of 61% in this series. There was no correlation between mechanism or location of penetration and the likelihood of clinically significant injury. We conclude that recent recommendations suggesting that arteriography is unnecessary in asymptomatic patients with penetrating neck trauma are premature. Further investigations of larger patient samples are necessary to determine if "proximity" should be abandoned as an indication for arteriography. We advocate that, until additional data are accumulated, urgent arteriography and esophagography or operative exploration are indicated in stable asymptomatic patients with neck wounds which violate the platysma.     

Management of penetrating neck injuries

In 44 patients neck wounds penetrating the platysma were evaluated over a 5-year period. Twenty-one patients were admitted and observed; 22 patients were explored immediately. One was dead upon arrival in the emergency room. The decision to explore was based upon initial clinical evaluation using criteria of unstable vital signs, bleeding, hematoma, subcutaneous emphysema, respiratory distress, or neurologic deficits. Of the 21 patients selected for observation, none had complications or required later surgery. There was a negative exploration rate of 23%. Had all patients been explored, the negative exploration rate would have been 60%. We conclude that selective exploration, based upon careful clinical evaluation, is both safe and reasonable in cases of penetrating neck trauma.     

Traumatic gunshot wounds of neck, thorax and abdomen

Basing on the largest experience in the country, authors characterize the dynamics of growth, localizaton and severity of wounds from traumatic (nonlethal) weapon. Every third victim with neck wound had deep neck structures damage. Open wounds of thorax and abdomen, though performed from traumatic weapon, pose a certain life threat.     

Tracheobronchoscopy in injuries of the thorax and neck]

The results of examination and treatment of patients with penetrating wounds of the thorax and the neck are analysed. Diagnostic potential abilities of roentgenography and tracheobronchoscopy are evaluated comparatively. High diagnostic and curative effectiveness of tracheobronchoscopy is detected, which is indicated in diagnosis of the wounds of the larynx and the trachea as well as in cases of technical difficulties during endotracheal intubation. Besides, tracheobronchoscopy is indicated in postoperative period for sanation of the tracheobronchial tree under visual control for prevention of broncho-pulmonary complications.     

The contemporary management of penetrating splenic injury

Introduction

Selective non-operative management (NOM) is standard of care for clinically stable patients with blunt splenic trauma and expectant management approaches are increasingly utilised in penetrating abdominal trauma, including in the setting of solid organ injury. Despite this evolution of clinical practice, little is known about the safety and efficacy of NOM in penetrating splenic injury.

Methods

Trauma registry and medical record review identified all consecutive patients presenting to LAC+USC Medical Center with penetrating splenic injury between January 2001 and December 2011. Associated injuries, incidence and nature of operative intervention, local and systemic complications and mortality were determined.

Results

During the study period, 225 patients experienced penetrating splenic trauma. The majority (187/225, 83%) underwent emergent laparotomy. Thirty-eight clinically stable patients underwent a deliberate trial of NOM and 24/38 (63%) were ultimately managed without laparotomy. Amongst patients failing NOM, 3/14 (21%) underwent splenectomy while an additional 6/14 (42%) had splenorrhaphy. Hollow viscus injury (HVI) occurred in 21% of all patients failing NOM. Forty percent of all NOM patients had diaphragmatic injury (DI). All patients undergoing delayed laparotomy for HVI or a splenic procedure presented symptomatically within 24 h of the initial injury. No deaths occurred in patients undergoing NOM.

Conclusions

Although the vast majority of penetrating splenic trauma requires urgent operative management, a group of patients does present without haemodynamic instability, peritonitis or radiologic evidence of hollow viscus injury. Management of these patients is complicated as over half may remain clinically stable and can avoid laparotomy, making them potential candidates for a trial of NOM. HVI is responsible for NOM failure in up to a fifth of these cases and typically presents within 24 h of injury. Delayed laparotomy, within this limited time period, did not appear to increase mortality nor preclude successful splenic salvage. In clinically stable patients, diagnostic laparoscopy remains essential to evaluate and repair occult DI. As NOM for penetrating abdominal trauma becomes more common, multi-centre data is needed to more accurately define the principles of patient selection and the limitations and consequences of this approach in the setting of splenic injury.
