Challenges in war-related thoracic injury faced by French military surgeons in Afghanistan (2009-2013).

BACKGROUND This study reports the challenges faced by French military surgeons in the management of thoracic injury during the latest Afghanistan war. METHODS From January 2009 to April 2013, all of the civilian, French and Coalition casualties admitted to French NATO Combat Support Hospital situated on Kabul were prospectively recorded in the French Military Health Service Registry (OPEX(®)). Only penetrating and blunt thoracic trauma patients were retrospectively included. RESULTS Eighty-nine casualties were included who were mainly civilian (61%) and men (94%) with a mean age of 27.9 years old. Surgeons dealt with polytraumas (78%), severe injuries (mean Injury Severity Score=39.2) and penetrating wounds (96%) due to explosion in 37%, gunshot in 53% and stabbing in 9%. Most of casualties were first observed or drained (n=56). In this non-operative group more than 40% of casualties needed further actions. In the operative group, Damage Control Thoracotomy (n=22) was performed to stop ongoing bleeding and air leakage and Emergency Department Thoracotomy (n=11) for agonal patient. Casualties suffered from hemothorax (60%), pneumothorax (39%), diaphragmatic (37%), lung (35%), heart or great vessels (20%) injuries. The main actions were diaphragmatic sutures (n=25), lung resections (wedge n=6, lobectomy n=4) and haemostasis (intercostal artery ligation n=3, heart injury repairs n=5, great vessels injury repairs n=5). Overall mortality was 11%. The rate of subsequent surgery was 34%. CONCLUSIONS The analysis of the OPEX(®) registry reflects the thoracic surgical challenges of general (visceral) surgeons serving in combat environment during the latest Afghanistan War.

Feasibility of selective non-operative management for penetrating abdominal trauma in France

INTRODUCTION In France, non-operative management (NOM) is not the widely accepted treatment for penetrating wounds. The aim of our study was to evaluate the feasibility of NOM for the treatment of penetrating abdominal traumas at 3 hospitals in the Southeast of France. METHODOLOGY Our study was multicentric and retroprospective from January, 2010 to September, 2013. Patients presenting with a penetrating abdominal stab wound (SW) or gunshot wound (GSW) were included in the study. Those with signs of acute abdomen or hemodynamic instability had immediate surgery. Patients who were hemodynamically stable had a CT scan with contrast. If no intra-abdominal injury requiring surgery was evident, patients were observed. Criteria evaluated were failed NOM and its morbidity, rate of non-therapeutic procedures (NTP) and their morbidity, length of hospital stay and cost analysis. RESULTS One hundred patients were included in the study. One patient died at admission. Twenty-seven were selected for NOM (20 SW and 7 GSW). Morbidity rate was 18%. Failure rate was 7.4% (2 patients) and there were no mortality. Seventy-two patients required operation of which 22 were NTP. In this sub-group, the morbidity rate was 9%. There were no mortality. Median length of hospital stay was 4 days for the NOM group and 5.5 days for group requiring surgery. Cost analysis showed an economic advantage to NOM. CONCLUSION Implementation of NOM of penetrating trauma is feasible and safe in France. Indications may be extended even for some GSW. Clinical criteria are clearly defined but CT scan criteria should be better described to improve patient selection. NOM reduced costs and length of hospital stay.

Original articleResuscitation thoracotomy

Resuscitation thoracotomy is a rarely performed procedure whose use, in France, remains marginal. It has five specific goals that correspond point-by-point to the causes of traumatic cardiac arrest: decompression of pericardial tamponade, control of cardiac hemorrhage, performance of internal cardiac massage, cross-clamping of the descending thoracic aorta, and control of lung injuries and other intra-thoracic hemorrhage. This approach is part of an overall Damage Control strategy, with a targeted operating time of less than 60minutes. It is indicated for patients with cardiac arrest after penetrating thoracic trauma if the duration of cardio-pulmonary ressuscitation (CPR) is <15minutes, or <10minutes in case of closed trauma, and for patients with refractory shock with systolic blood pressure <65mm Hg. The overall survival rate is 12% with a 12% incidence of neurological sequelae. Survival in case of penetrating trauma is 10%, but as high as 20% in case of stab wounds, and only 6% in case of closed trauma. As long as the above-mentioned indications are observed, resuscitation thoracotomy is fully justified in the event of an afflux of injured victims of terrorist attacks.

Management specificities for abdominal, pelvic and vascular penetrating trauma

Management of patients with penetrating trauma of the abdomen, pelvis and their surrounding compartments as well as vascular injuries depends on the patients hemodynamic status. Multiple associated lesions are the rule. Their severity is directly correlated with initial bleeding, the risk of secondary sepsis, and lastly to sequelae. In patients who are hemodynamically unstable, the goal of management is to rapidly obtain hemostasis. This mandates initial laparotomy for abdominal wounds, extra-peritoneal packing (EPP) and resuscitative endovascular balloon occlusion of the aorta (REBOA) in the emergency room for pelvic wounds, insertion of temporary vascular shunts (TVS) for proximal limb injuries, ligation for distal vascular injuries, and control of exteriorized extremity bleeding with a tourniquet, compressive or hemostatic dressings for bleeding at the junction or borderline between two compartments, as appropriate. Once hemodynamic stability is achieved, preoperative imaging allow more precise diagnosis, particularly for retroperitoneal or thoraco-abdominal injuries that are difficult to explore surgically. The surgical incisions need to be large, in principle, and enlarged as needed, allowing application of damage control principles.

Specific elements of thoracic wound management

Damage control for thoracic trauma combines definitive and temporary surgical gestures specifically adapted to the lesions present. A systematic assessment of all injuries to prioritize the specific lesions and their treatments constitutes the first operative stage. Packing and temporary closure have a place in the care of chest injuries.
