Pulmonary tractotomy versus lung resection: viable options in penetrating lung injury.

BACKGROUND: Emergency lung resection following penetrating chest trauma has been associated with mortality rates as high as 55-100%. Pulmonary tractotomy is advocated as a rapid alternative method of dealing with deep lobar injuries. We reviewed our experience with resection and tractotomy to determine whether method of management affects mortality or if patient presentation is more critical in determining outcome. METHODS: A retrospective review of all patients with chest injury seen at an urban Level I trauma center from 2/89-1/99 was performed. All patients undergoing parenchymal surgery were included. Records were abstracted for grade of injury, type of resection, presenting systolic blood pressure (SBP), temperature, Injury Severity Score (ISS), operative time, and estimated blood loss (EBL). Mortality and thoracic complications were compared between groups. RESULTS: Two hundred forty-six of 2736 patients with penetrating chest trauma underwent thoracotomy, with 70 (28%) requiring some form of lung resection. There were 11 (15.7%) deaths. Patients who died had lower SBP (53 +/- 32 mm Hg vs 77 +/- 28 mm Hg), lower temperature (32.5 degrees +/- 1.3 degrees C vs 34.3 degrees +/- 1.2 degrees C), higher ISS (33 +/- 13 vs 23 +/- 9), and greater EBL (9.8 +/- 4.3 liters vs 2.8 +/- 2.1 liters) compared with survivors (p < 0.05 for all). Mortality was also increased in the presence of cardiac injury (33% with vs 12% without) and the need for laparotomy (26% with vs 9% without) (p < 0.05 for all). Tractotomy was associated with an increased incidence of chest complications (67% vs 24%, p = 0.05) compared with lobectomy with no difference in presenting physiology, operative time, or mortality. CONCLUSION: Lung resection for penetrating injuries can be done safely with morbidity and mortality rates lower than previously reported. Patient outcome is related to severity of injury rather than type of resection. Tractotomy is associated with a higher incidence of infectious complications and is not associated with shortened operative times or survival.     

Lung-sparing surgery after penetrating trauma using tractotomy, partial lobectomy, and pneumonorrhaphy

OBJECTIVE: To evaluate the role of lung-sparing surgical techniques in the surgical management of penetrating pulmonary injuries. DESIGN: Retrospective case series. SETTING: Academic level I trauma center. PATIENTS AND METHODS: Forty patients underwent thoracic surgery for penetrating lung injuries during a 63-month period from January 1993 to March 1997. Five (12.5%) underwent anatomical lobectomy, 3 (7.5%) pneumonorrhaphy, 9 (22.5%) stapled wedge resection, and 23 (57.5%) stapled tractotomy. In total, 34 patients (85%) were treated with stapling techniques (1 anatomical lobectomy, 1 pneumonorrhaphy, 9 stapled wedge resections, and 23 stapled tractotomies) and 35 (87.5%) underwent had lung-sparing surgery for trauma. RESULTS: Morbidity and mortality rates were 40% and 5%, respectively. Patients who underwent anatomical lobectomy required longer mechanical ventilatory support, intensive care unit stay, and hospital stay and had a higher morbidity rate compared with patients who underwent lung-sparing surgery for trauma but had central and extensive pulmonary injuries. Stapled tractotomy was efficient in controlling bleeding and bronchial leaks, but, in 3 patients, parts of the divided lung parenchyma were devascularized and had to be resected. CONCLUSIONS: Lung-sparing surgery for trauma with the use of staplers can be used in the majority of patients with penetrating pulmonary injuries requiring operation. Stapled tractotomy is a rapid and effective method for controlling hemorrhage and air leaks.     

Surgical management of traumatic pulmonary injury

BACKGROUND: Surgical treatment of traumatic pulmonary injuries requires knowledge of multiple approaches and operative interventions. We present a 15year experience in treatment of traumatic pulmonary injuries. We hypothesize that increased extent of lung resection correlates with higher mortality. METHODS: Surgical registry data of a level 1 trauma center was retrospectively reviewed from 1984 to 1999 for traumatic lung injuries requiring operative intervention. Epidemiologic, operative, and hospital mortality data were obtained. RESULTS: Operative intervention for traumatic pulmonary injuries was required in 397 patients, of whom 352 (89%) were men. Penetrating trauma was seen in 371 (93%) patients. Location of the injuries was noted in the left side of the chest in 197 (50%), right side of the chest in 171 (43%), and bilateral in 29 (7%). Operative interventions included pneumonorraphy (58%), wedge resection or lobectomy in (21%), tractotomy (11%), pneumonectomy (8%), and evacuation of hematoma (2%). Overall mortality was 27%. If concomitant laparotomy was required, mortality increased to 33%. The mortality rate in the pneumonectomy group was 69.7%. CONCLUSIONS: The majority of lung injuries occurred in males due to penetrating trauma. Surgical treatment options ranged from simple oversewing of bleeding injury to rapid pneumonectomy. Mortality increased as the complexity of the operative intervention increased. Rapid intraoperative assessment and appropriate control of the injury is critical to the successful management of traumatic lung injury.     

Management of traumatic lung injury: a Western Trauma Association Multicenter review.

BACKGROUND: Improved outcomes following lung injury have been reported using "lung sparing" techniques. METHODS: A retrospective multicenter 4-year review of patients who underwent lung resection following injury was performed. Resections were categorized as "minor" (suture, wedge resection, tractotomy) or "major" (lobectomy or pneumonectomy). Injury severity, Abbreviated Injury Scale (AIS) score, and outcome were recorded. RESULTS: One hundred forty-three patients (28 blunt, 115 penetrating) underwent lung resection after sustaining an injury. Minor resections were used in 75% of cases, in patients with less severe thoracic injury (chest AIS scores "minor" 3.8 +/- 0.9 vs. "major" 4.3 +/- 0.7, p = 0.02). Mortality increased with each step of increasing complexity of the surgical technique (RR, 1.8; CI, 1.4-2.2): suture alone, 9% mortality; tractotomy, 13%; wedge resection, 30%; lobectomy, 43%; and pneumonectomy, 50%. Regression analysis demonstrated that blunt mechanism, lower blood pressure at thoracotomy, and increasing amount of the lung resection were each independently associated with mortality. CONCLUSION: Blunt traumatic lung injury has higher mortality primarily due to associated extrathoracic injuries. Major resections are required more commonly than previously reported. While "minor" resections, if feasible, are associated with improved outcome, trauma surgeons should be facile in a wide range of technical procedures for the management of lung injuries.     

Comparison of penetrating injuries of the right and left colon.

Controversy still exists whether penetrating injuries of the right colon have more favorably than those to the left. The importance of the issue rests in the operative management. This is a review of 50 cases of penetrating injuries of the right colon and 55 of the left treated at our institution from 1975 to 1980. The two patient groups were similar with respect to mechanism of injury, presence of shock at admission, degree of fecal contamination, severity of injury, and the percentage of cases with associated intra-abdominal injuries. The number of patients managed by primary repair or resection (52 vs. 45%), repair or resection with exteriorization (20 vs. 22%), and colostomy (28 vs. 33%) were also comparable in right versus left injuries. The treatment of right colon injuries resulted in 32% morbidity rate and 2% mortality rate, and that of left sided injuries 33% morbidity and rate of 4% mortality rate. These findings indicate that, despite known anatomic and physiologic differences, penetrating trauma to the right and left colon should be managed similarly.     

Pulmonary Resection for Lung Trauma

Background. Pulmonary resection is rarely required for trauma, and its mortality is reportedly high.

Methods. A 10-year retrospective review of pulmonary resections for trauma was done.

Results. Of 2,455 patients with chest trauma, 183 (7.4%) underwent thoracotomy and 32 (1.3%) required pulmonary resection. Mean age was 28.4 years and mean injury severity score was 24.5. Mechanism of injury was stab wound in 14 patients, gunshot wound in 6, and blunt trauma in 12. Blunt trauma patients had a higher injury severity score (29.6) than penetrating trauma patients (21.4), but this was not significant (p < 0.07). Indications for thoracotomy were hemorrhage in 24 patients, airway disruption in 4, and other indications in 4. Operations consisted of wedge resection (19 patients), lobectomy (9), and pneumonectomy (4). Four (12.5%) patients (pneumonectomy, 2; lobectomy, 1; wedge, 1) died. Mortality for pneumonectomy was 50%, but this was not significantly higher than for lesser resections. Blunt trauma had a higher mortality (33%) than penetrating trauma (0%) (p < 0.02). Nonsurvivors had higher injury severity scores (44.2) than survivors (21.6) (p < 0.001).

Conclusions. Pulmonary resection is infrequently required for lung injury. Overall mortality is lower than previously reported, but pneumonectomy has a high mortality. Blunt trauma has a higher mortality than penetrating trauma. Injury severity scores are higher for nonsurvivors than survivors; this shows the importance of associated injuries on outcome.     

Outcome of lung trauma.

OBJECTIVE: To find out whether we could manage critical pulmonary haemorrhages in penetrating injuries, and to report our experience with blunt trauma of the lung. DESIGN: Retrospective study. SETTING: Teaching hospital, Sweden. SUBJECTS: 81 patients who presented with pulmonary injuries during the period January 1988-December 1997; 6 were penetrating and 75 blunt. RESULTS: There was only one patient with an isolated lung contusion. The remaining was divided into 2 groups: those with pulmonary contusion and thoracic lesions (n = 32), and those with pulmonary contusion and extrathoracic lesions (n = 42). Four patients in the penetrating group were shocked and required urgent operations; emergency room thoracotomy (n = 1), urgent thoracotomy (n = 2), and urgent thoracoabdominal exploration (n = 1) were done successfully. We correlated grade of lung injury [American Association for the Surgery of Trauma-Abbreviated Injury Scale (AIS)] with mortality. All patients with penetrating injuries survived without serious consequences. There were a mean (SD), of 6 (2) injuries/patient in those with extrathoracic injuries compared with 3 (1) injuries/patient in the group with thoracic lesions (p < 0.001). The corresponding hospital mortality was 6/42 (19%) mainly as a result of the central nervous system lesions (4/6) compared with 0/32. The mean (SD) Injury Severity Score (ISS) was 9.3 (4.8) in patients with thoracic lesions compared with 24.1 (14.7) in patients with extrathoracic lesions (p < 0.0001), and 14.9 (9.5) in all survivors compared with 49.9 (13.6) among those who died (p < 0.0001). CONCLUSIONS: An excellent outcome can be achieved managing penetrating injuries of the lung by an aggressive approach and urgent surgical intervention even when emergency room thoracotomy is essential. Pulmonary contusion is considered to be a relatively benign lesion that does not add to the morbidity or mortality in patients with blunt chest trauma. These data may help to decrease the obsession with pulmonary contusion in patients with chest trauma, with or without extrathoracic lesions, and avoid many unnecessary computed tomograms of the chest.     

Management of penetrating lung injuries in civilian practice

Recent reports of military thoracic injuries have advocated early thoracotomy and aggressive management of pulmonary injuries with resection as opposed to the more conservative and traditional treatment with chest tube thoracostomy. A retrospective study was therefore performed to determine the incidence of thoracotomy and lung resection in civilian injuries and to evaluate the effectiveness of treatment of these injuries. Between 1973 and 1985, in a series of 1,168 patients, there were 384 gunshot wounds and 784 stab wounds to the thorax. Two hundred eighty-three patients with a gunshot wound (74%) and 602 with a stab wound (77%) were treated with chest tubes alone. Sixty-eight patients (6% of the total) required operative repair of pulmonary hilar or parenchymal injury. Pulmonary resection was necessary in only 18 patients (nine with a gunshot wound and nine with a stab wound), and 10 patients had repair of hilar injuries (nine with a gunshot wound and one with a stab wound). Of patients requiring pulmonary resection, nine required wedge or segmental resection, six required lobectomy, and three patients required pneumonectomy. Mortality for all thoracic injuries was 2.3%: for those treated with chest tube alone, 0.7%; for pulmonary hilar injuries, 30%; for pulmonary parenchymal injuries, 8.6%; and for injuries necessitating lung resection, 28%. Most civilian lung injuries can be treated by tube thoracostomy alone. Although relatively few patients with primary pulmonary injury require thoracotomy, those that do are at significant risk and may require lung resection to control bleeding or hemoptysis or to remove destroyed or devitalized lung tissue.     

Improving outcomes following penetrating colon wounds: application of a clinical pathway

INTRODUCTION: During World War II, failure to treat penetrating colon injuries with diversion could result in court martial. Based on this wartime experience, colostomy for civilian colon wounds became the standard of care for the next 4 decades. Previous work from our institution demonstrated that primary repair was the optimal management for nondestructive colon wounds. Optimal management of destructive wounds requiring resection remains controversial. To address this issue, we performed a study that demonstrated risk factors (pre or intraoperative transfusion requirement of more than 6 units of packed red blood cells, significant comorbid diseases) that were associated with a suture line failure rate of 14%, and of whom 33% died. Based on these outcomes, a clinical pathway for management of destructive colon wounds was developed. The results of the implementation of this pathway are the focus of this report. METHODS: Patients with penetrating colon injury were identified from the registry of a level I trauma center over a 5-year period. Records were reviewed for demographics, injury characteristics, and outcome. Patients with nondestructive injuries underwent primary repair. Patients with destructive wounds but no comorbidities or large transfusion requirement underwent resection and anastomosis, while patients with destructive wounds and significant medical illness or transfusion requirements of more than 6 units/blood received end colostomy. The current patients (CP) were compared to the previous study (PS) to determine the impact of the clinical pathway. Outcomes examined included colon related mortality and morbidity (suture line leak and abscess). RESULTS: Over a 5.5-year period, 231 patients had penetrating colon wounds. 209 survived more 24 hours and comprise the study population. Primary repair was performed on 153 (73%) patients, and 56 patients had destructive injuries (27%). Of these, 40 (71%) had resection and anastomosis and 16 (29%) had diversion. More destructive injuries were managed in the CP group (27% vs. 19%). Abscess rate was lower in the CP group (27% vs. 37%), as was suture line leak rate (7% vs. 14%). Colon related mortality in the CP group was 5% as compared with 12% in the PS group. CONCLUSIONS: The clinical pathway for destructive colon wound management has improved outcomes as measured by anastomotic leak rates and colon related mortality. The data demonstrated the need for colostomy in the face of shock and comorbidities. Institution of this pathway results in colostomy for only 7% of all colon wounds.     

Pulmonary Tractotomy for a Patient with Traumatic Penetrating Lung Injury: Report of a Case

We report a case of traumatic hemopneumothorax caused by penetrating lung injury in a 26-year-old man. The patient underwent emergency thoractomy, which revealed hemorrhage in the lingular segment of the left lung. We found the bleeding point and controlled the hemorrhage using pulmonary tractotomy by inserting a linear stapler into the stab wound in the pulmonary parenchyma. The original technique of pulmonary tractotomy was performed for complete through-and-through injury by dividing the bridge of lung tissue between the aortic clamps. We were able to apply this procedure safely to stop bleeding from a stab wound that did not go through the lung. Thus, pulmonary tractotomy is an effective damage-control operation for the lung with obvious advantages over major lung resection.     

Lobectomie d’hémostase et ECMO : une association salvatrice après plaie pénétrante du thorax

The majority of chest penetrating trauma patients are successfully managed with tube thoracostomy and general supportive measures. Pulmonary resection for hemorrhagic shock is rarely required after trauma to control bleeding. Both pulmonary injury and massive blood transfusion can lead to acute respiratory distress syndrome (ARDS). The mortality rate in these patients reaches up to 40% despite advanced ventilatory treatment. The use of extracorporeal membrane oxygenation (ECMO) can be started as rescue therapy. We report a case of 24-year-old man with major hemorrhagic shock with cardiac arrest and ARDS after traumatic penetrating lung injury that was successfully treated with pulmonary resection and ECMO.     

Penetrating injuries of the subclavian artery

BACKGROUND: Penetrating injuries of the subclavian artery occurs infrequently but represent a surgical challenge. We reviewed our experience with penetrating injury of the subclavian artery and identify factors that influenced morbidity and mortality. METHODS: A retrospective review was performed on 54 consecutive patients who sustained penetrating injury to the subclavian artery during a 10-year period. RESULTS: The causes of injuries were gunshot wounds in 46 patients (85%), stab wounds in 5 patients (9%), and shotgun wounds in 3 patients (6%). The overall mortality was 39%. Operative management of the subclavian artery injury included primary repair in 38 patients, interposition grafting in 13 patients, and ligation in 3 patients. The most common associated injury was subclavian vein (44%) followed by brachial plexus (31%). Predictors of survivability include mechanism of penetrating injuries, hemodynamic status of patients on arrival, and three or more associated injuries involving other structures. Associated brachial plexus injury accounts for the majority of long-term morbidity in survivors. CONCLUSIONS: Penetrating injuries of the subclavian artery are associated with high morbidity and mortality. Multiple concomitant injuries, unstable vital signs upon presentation, and gun shot injuries greatly increase mortality.     

Hepatic injuries: management and outcome.

A total of 52 patients with different grades of liver injuries were treated in a 1 year period: 32 patients had penetrating injuries and in 20 patients injuries resulted from blunt trauma. Blunt trauma victims were frequently associated with chest and head injuries and with skeletal fractures. A 4-fold incidence of associated intra-abdominal injuries was encountered in penetrating trauma victims. Blunt and gunshot victims commonly had severe grades of liver injuries (55% and 83.3%, respectively). Stab wounds caused simpler grades of injuries (86.7%). Suture hepatorraphy was the commonest procedure performed (57.7%).The other procedures applied to treat the injured liver were: selective ligation of the injured blood vessels (15.4%); packing (7.7%); and liver resection (3.8%). Two patients died on the operating table before any remedy was applied. The overall morbidity was 40.4%. The liver related complications constituted 17.3%. The total mortality was 13.5% and the liver related mortality was 9.6%.     

Complications following blunt and penetrating injuries in 216 victims of chest trauma requiring tube thoracostomy

Tube thoracostomy (TT) is required in the treatment of many blunt and penetrating injuries of the chest. In addition to complications from the injuries, TT may contribute to morbidity by introducing microorganisms into the pleural space or by incomplete lung expansion and evacuation of pleural blood. We have attempted to assess the impact of TT following penetrating and blunt thoracic trauma by examining a consecutive series of 216 patients seen at two urban trauma centers with such injuries who required TT over a 30-month period. Ninety-four patients suffered blunt chest trauma; 122 patients were victims of penetrating wounds. Patients with blunt injuries had longer ventilator requirements (12.6 +/- 14 days vs. 3.7 +/- 7.1 days, p = 0.003), longer intensive care stays (12.2 +/- 12.5 days vs. 4.1 +/- 7.5 days, p = 0.001), and longer periods of TT, (6.5 +/- 4.9 days vs. 5.2 +/- 4.5 days, p = 0.018). Empyema occurred in six patients (3%). Residual hemothorax was found in 39 patients (18%), seven of whom required decortication. Recurrent pneumothorax developed in 51 patients (24%) and ten required repeat TT. Complications occurred in 78 patients (36%). Patients with blunt trauma experienced more complications (44%) than those with penetrating wounds (30%) (p = 0.04). However, only seven of 13 patients developing empyema or requiring decortication had blunt trauma. Despite longer requirements for mechanical ventilation, intensive care, and intubation, victims of blunt trauma seemed to have effective drainage of their pleural space by TT without increased risk of infectious complications.     

Management of carotid artery injuries: Louisiana State University Shreveport experience

BACKGROUND: Traumatic carotid artery injury is an infrequently encountered surgical entity. Carotid artery injuries in polytrauma patients can be easily missed in the absence of clinical findings and/or presence of confounding concurrent injuries. METHODS: Between 1991 and 1998, 23 patients were diagnosed with various carotid artery injuries at the trauma center of Louisiana State University Health Sciences Center, Shreveport, Louisiana. Injuries were assessed by angiography and/or surgical exploration of the neck. Clinical presentations, radiologic features, management strategies, and neurologic outcomes were statistically analyzed and compared with the existing literature. RESULTS: Twelve patients (52%) had penetrating carotid artery injuries, while 11 (48%) had blunt trauma. The diagnosis of carotid injury was significantly delayed in the group with blunt trauma as opposed to those with penetrating wounds. Surgical repair was performed in 6 (26%) patients; 2 (8%) underwent balloon occlusion, while ligation was conducted in 2 (8%) patients. Thirteen patients (57%) were treated conservatively with anticoagulants. Six patients (26%) died, while another 6 (26%) had permanent neurologic deficit. Mortality and morbidity was significantly higher in the group with penetrating injuries. A statistical analysis showed that multi-level carotid injury (p < 0.002) and increasing age (p < 0.001) had a significantly higher mortality. CONCLUSIONS: Injury to carotid arteries results in significant mortality and morbidity. Our results indicate that penetrating carotid injury at more than one level carries higher mortality and morbidity rates than blunt injury. Furthermore, early identification of the injured segment may favorably influence the outcome for such patients.     

Penetrating chest wounds: 24 years experience

Thoracic and thoracoabdominal penetrating wounds are frequently encountered in urban medical centers in the United States. This study was undertaken to determine the clinical characteristics and in hospital outcome of these injuries. This was a longitudinal, nonblinded study using the established standard of care of patients with penetrating chest trauma. It consists of an analysis of a consecutive series of 3049 patients treated at one trauma center between April 1972 and March 1996. There were 1347 stab wounds and 1702 gunshot wounds. Antibiotic prophylaxis was administered to patients who underwent laparotomy or thoracotomy or who had lung contusion with hemoptysis (41.6%, 1296/3049). Of 3049 patients, 196 had cardiac injuries. All of them underwent thoracotomy, and the mortality was 21.9%. In contrast, among 2853 patients without cardiac injuries, only 257 (9%) required thoracotomy; the mortality in this group was 1.5%. Patients with thoracoabdominal injuries (899/3049) had a mortality of 4.3% compared to 2.1% among those who had isolated chest injuries. The overall mortality was 2.8%. Of 1702 patients with gunshot wounds, 85 (5%) sustained transaxial injuries, with an overall mortality of 36.5%. The complication rate among the survivors was 6% with only 2.5% being infectious. We conclude that the mortality for noncardiac penetrating injuries of the chest is low. The presence of associated abdominal injuries increases the mortality twofold. More than one-third of the patients with transaxial wounds die. Gunshot wounds of the heart result in higher mortality than stab wounds to the heart. The infection rate is low.     

Management of penetrating laryngotracheal injuries

Background. Penetrating Iaryngotracheal injuries are uncommon; however, these injuries are associated with significant morbidity and mortality. In an attempt to define the management of penetrating laryngotracheal injuries, we reviewed our experience with these injuries. Methods. We retrospectively analyzed the records of all patients admitted to a Level I trauma center who required operative management for penetrating laryngotracheal injuries. During the period of this study all patients with penetrating neck injuries were managed according to a protocol of selective exploration. Results. Of fifty-seven patients with penetrating laryngotracheal injury 32 patients sustained gunshot wounds and 25 had stab wounds. The injuries were to the larynx in 24 (42%) and trachea in 33 (58%). Forty-six (81%) had isolated airway injuries and 11 (19%) had combined airway and digestive-tract injuries. Emergent airway management in 32 (56%) patients included: tracheostomy (15), endotracheal intubation (14), and cricothyroidotomy (3). Respiratory distress and subcutaneous crepitus were the commonest clinical findings. Diagnostic evaluation included: Iaryngoscopy/tracheoscopy (17), esophagoscopy (12), contrast esophagography (9), angiography (8), and bronchoscopy (3). Repair of laryngotracheal and esophageal injury was performed in the majority of patients. Selected patients with milder Iaryngotracheal injury did not have tracheostomy performed, with no increase in morbidity or mortality. There were 2 (3.5%) early deaths from associated major vascular injury. Conclusion. Mortality can be minimized by aggressive airway control. Endotracheal intubation can be accomplished safely in selected patients with penetrating laryngotracheal injuries. Digestive-tract injuries can often clinically occult and contribute significantly to morbidity and mortality; therefore, early evaluation of the esophagus is vital. Simple repair of Iaryngotracheal and digestive-tract injuries can be performed safely with good results. In patients with minor injuries, tracheostomy does not appear to be mandatory. © 1995 Jons Wiley & Sons, Inc.     

Lung Sparing Damage Control Surgery for Major Thoracic Trauma—A 5-year Experience*

Abstract This prospective study was carried out to compare the outcome of lung sparing damage control surgery versus major pulmonary resections for extensive thoracic trauma. Methods: The study analyses the results of 52 trauma victims who underwent thoracotomy for pulmonary injuries over a period of 5 years. Operative techniques, postoperative complications and mortality were assessed in both groups, results analysed with the help of Fisher’s exact test and Chi-square test and the analysis of variance for comparative analysis carried out with SPSS 10.0. Results: Penetrating trauma was the main cause of thoracic injuries affecting 39/52 patients. Associated injuries were found in 9/13 blunt trauma victims, but only in 11/39 penetrating trauma sufferers. The morbidity and mortality were significantly higher after major resections, 6/11 and 2/11, as compared to lung sparing surgery, 10/41 and 2/41, respectively (p = 0.001). Conclusion: We recommend the use of lung sparing damage control techniques to manage major thoracic trauma requiring surgical intervention. Lung sparing surgery is an effective and much safer option as compared to major pulmonary resection when treating extensive lung trauma. * The preliminary results of the study were presented in the Irish Thoracic Society Annual Meeting in Belfast, UK on 14–15th November 2003 and the abstract was published in Irish Journal of Medical Science (Ir J Med Sci 2003; 172 suppl. 2).     

Minithoracotomy combined with mechanically stapled bronchial and vascular ligation for anatomical lung resection

BACKGROUND: The most appropriate approach to anatomic pulmonary resection has been debated with the advance of minimally invasive techniques and especially the common use of mechanical staplers. Video assisted surgery and muscle-sparing thoracotomy are established options of surgical approach for lung resection. We utilize a combined technique of vertical muscle sparing minithoracotomy and mechanical closure of the hilum structures to accomplish lung resection. METHODS: From December 1995 through January 2002, 713 patients (mean age, 65 +/- 11, 44.6% male) underwent anatomic pulmonary resection including 64 pneumonectomies, 514 lobectomies, and 135 formal segmental resections. Pulmonary resection was approached though a direct access, vertical, minithoracotomy (< 10 cm), and vascular ligation was performed with port-access endostapling instrumentation. Full mediastinal lymph node sampling was performed for primary lung cancer. RESULTS: The average operative time was 55 minutes for lobectomy-formal segmentectomy and 62 minutes for pneumonectomy. An average of 3.6 staple applications were utilized to ligate the pulmonary vasculature (n = 2548 for 713 patients). Operative vascular complications included 5 minor intimal fractures, 1 posterior segmental arterial avulsion, and 1 staple misfiring for an adverse event rate during stapler application of 0.27%. Only one conversion to standard thoracotomy was necessary to control bleeding from the pulmonary vein. There were no intraoperative deaths. CONCLUSIONS: Vertical minithoracotomy is a safe and expedited approach for anatomic lung resection. Direct visualization for dissection and effective pulmonary hilum mechanical closure with staplers were demonstrated. This approach is a reasonable option when a complete video-assisted surgery seems to be hazardous and a full open thoracotomy could represent an additional morbidity.     

Gall bladder injuries as part of the spectrum of civilian abdominal trauma in South Africa

BACKGROUND: Trauma to the gall bladder is rare, but when missed or improperly managed it may be associated with significant morbidity. The aim of the present study was to review the management and outcomes of gall bladder trauma in a trauma centre. METHODS: Forty-three patients with gall bladder injury due to abdominal trauma were reviewed over a 3-year period. Surgical management, associated injuries, morbidity and mortality rates were determined. RESULTS: Among 1242 patients undergoing laparotomy for acute trauma, 43 patients (3.46%) with gall bladder injuries were identified. Forty patients sustained penetrating injuries (37 with gunshot wounds and three with stab wounds), and three patients suffered from blunt trauma. All patients with gall bladder injury underwent abdominal exploration because of associated intra-abdominal injuries. Thirty-six patients were treated with cholecystectomy, four patients underwent primary suture repair of the gall bladder perforation, while three patients with gall bladder injury were treated without any surgical intervention at laparotomy. No complications could be attributed to the gall bladder trauma or surgery. CONCLUSION: Cholecystectomy is the preferred procedure of choice for gall bladder injuries and is associated with no morbidity.
