Selective nonoperative management of liver gunshot injuries.

Objective:Nonoperative management (NOM) of liver gunshot injuries is yet to gain general acceptance. The aim of this study was to assess the feasibility and safety of selective NOM of liver gunshot injuries. Patients and Methods:A prospective, protocol-driven study, which included all liver gunshot injuries admitted to a level I trauma center, was conducted over a 4-year period. Patients with right-sided thoracoabdominal, and right upper quadrant gunshot wounds with or without localized right upper quadrant tenderness underwent contrasted abdominal computed tomography scan evaluation to detect the presence of a liver injury. Patients with confirmed liver injuries were observed with serial clinical examinations. Outcome parameters included need for delayed laparotomy, complications, length of hospital stay, and survival. Results:During the study period, 63 patients with liver gunshot injuries were selected for NOM. The mean injury severity score was 19.6 (range, 4–34). Simple liver injuries (grades I and II) occurred in 26 (41.3%) patients and complex liver injuries (grades III, IV, and V) occurred in 37 (58.7%) patients. Associated injuries included 14 (22.2%) kidney, 44 (69.8%) diaphragm, 43 (68.3%) lung contusion, 42 (66.7%) hemothorax and/or pneuomothorax, and 21 (33.3%) rib fractures. Five patients required delayed laparotomy resulting in successful NOM rate of 92%. Complications included liver abscess (3), biliary fistula (3), retained hemothorax (4), and nosocomial pneumonia (5). The mean hospital stay was 6.1 (range, 3–23 days). There was no mortality. Conclusion:The NOM of appropriately selected patients with liver gunshot injuries is feasible, safe, and effective, regardless of the liver injury severity.

Civilian Extraperitoneal Rectal Gunshot Wounds: Surgical Management Made Simpler

BackgroundRectal injuries are associated with significant morbidity and mortality. Controversy persists regarding routine presacral drainage, distal rectal washout (DRW), and primary repair of extraperitoneal rectal injuries. This retrospective review was performed to determine the outcome of rectal injuries in an urban trauma center with a high incidence of penetrating trauma where a non-aggressive surgical approach to these injuries is practiced.MethodsThe records of all patients with a full-thickness penetrating rectal injury admitted to the Trauma Center at Groote Schuur Hospital over a 4-year period were reviewed. These were reviewed for demographics, injury mechanism and perioperative management, anatomical site of the rectal injury, associated intra-abdominal injuries and their management. Infectious complications and mortality were noted. Intraperitoneal rectal injuries were primarily repaired, with or without fecal diversion. Extraperitoneal rectal injuries were generally left untouched and a diverting colostomy was done. Presacral drainage and DRW were not routinely performed.ResultsNinety-two patients with 118 rectal injuries [intraperitoneal (7), extraperitoneal (59), combined (26)] were identified. Only two extraperitoneal rectal injuries were repaired. None had presacral drainage. Eighty-six sigmoid loop colostomies were done. Two (2.2%) fistula, one rectocutaneous, and one rectovesical, were recorded. There were nine (9.9%) infectious complications: surgical site infection (4), buttock abscess (1), buttock necrosis (1), pubic ramus osteitis (1), septic arthritis (2). No perirectal sepsis occurred.ConclusionsExtraperitoneal rectal injuries due to low-velocity trauma can be safely managed by fecal diversion alone.

Analysis of 203 Patients with Penetrating Neck Injuries

BackgroundSelective nonoperative management (SNOM) of penetrating neck injuries (PNI) has steadily gained favor, but indications for surgery and adjunctive diagnostic studies remain debated. The purpose of the present study is to validate a protocol of SNOM of PNI based on physical examination, which further dictates complementary investigations and management.Patients and methodsA prospective observational study was conducted in a South African tertiary urban trauma center with a high prevalence of penetrating trauma. All consecutive patients admitted with penetrating neck injuries over a 13-month period were included.ResultsA total of 203 patients were included in the study: 159 with stab wounds and 42 with gunshot wounds. A vascular injury was identified in 27 (13.3%) patients, pharyngoesophageal injury in 18 (8.9%) patients, and an upper airway injury in 8 (3.9%) patients. Only 25 (12.3%) patients required surgical intervention. A further 8 (3.9%) patients had therapeutic endovascular procedures. The remaining 158 (77.8%) patients, either asymptomatic or with negative work-up, were managed expectantly. There were no clinically relevant missed injuries.ConclusionsSelective nonoperative management of neck injuries based on clinical examination and selective use of adjunctive investigational studies is safe in a high-volume trauma center.

Sternotomy or drainage for a hemopericardium after penetrating trauma: a randomized controlled trial.

Objective:To determine if stable patients with a hemopericardium detected after penetrating chest trauma can be safely managed with pericardial drainage alone. Background:The current international practice is to perform a sternotomy and cardiac repair if a hemopericardium is detected after penetrating chest trauma. The experience in Cape Town, South Africa, on performing a mandatory sternotomy in hemodynamically stable patients was that a sternotomy was unnecessary and the cardiac injury, if present, had sealed. Methods:A single-center parallel-group randomized controlled study was completed. All hemodynamically stable patients with a hemopericardium confirmed at subxiphoid pericardial window (SPW), and no active bleeding, were randomized. The primary outcome measure was survival to discharge from hospital. Secondary outcomes were complications and postoperative hospital stay. Results:Fifty-five patients were randomized to sternotomy and 56 to pericardial drainage and wash-out only. Fifty-one of the 55 patients (93%) randomized to sternotomy had either no cardiac injury or a tangential injury. There were only 4 patients with penetrating wounds to the endocardium and all had sealed. There was 1 death postoperatively among the 111 patients (0.9%) and this was in the sternotomy group. The mean intensive care unit (ICU) stay for a sternotomy was 2.04 days (range, 0–25 days) compared with 0.25 days (range, 0–2) for the drainage (P < 0.001). The estimated mean difference highlighted a stay of 1.8 days shorter in the ICU for the drainage group (95% CI: 0.8–2.7). Total hospital stay was significantly shorter in the SPW group (P < 0.001; 95% CI: 1.4–3.3). Conclusions:SPW and drainage is effective and safe in the stable patient with a hemopericardium after penetrating chest trauma, with no increase in mortality and a shorter ICU and hospital stay.

Evisceration Following Abdominal Stab Wounds: Analysis of 66 Cases

BackgroundAbdominal stab wounds with evisceration remain an indication for emergency laparotomy. The purpose of this study was validate a policy of mandatory laparotomy for organ evisceration and a policy of selective nonoperative management with serial physical abdominal examination for omentum evisceration.MethodsThe charts of 379 patients with abdominal stab wounds who presented to our Level I trauma center over a 3-year (January 2005 to December 2007) period were retrospectively reviewed. Altogether, 66 (17.4%) patients with evisceration were identified and included in the study. Indications for mandatory laparotomy were peritonitis, hemodynamic instability, organ evisceration, and a high spinal cord or severe head injury with an abdominal stab wound. Further data gathered included the organ eviscerated, intraabdominal organs injured, and complications. Injury severity was categorized using the revised trauma score (RTS), injury severity score (ISS), and penetrating abdominal index (PATI).ResultsOrgan and omentum evisceration occurred in 35 (53%) and 31 (47%) patients, respectively. Organs eviscerated were as follows (number of patients): small bowel in 27 (40.9%), stomach in 2 (3%), colon in 1 (1.5%), small bowel and stomach in 2 (3%), and small bowel and colon in 3 (4.5%). The mean RTS, ISS, and PATI scores were 7.71, 13.74, and 8.26, respectively. Only two (5.7%) patients with organ evisceration underwent a negative laparotomy. In total, 23 patients with omentum evisceration (21 with peritonitis, 1 with a head injury, 1 who failed abdominal observation) underwent therapeutic laparotomy. Six patients with omentum evisceration were managed successfully nonoperatively. Two patients with left thoracoabdominal omentum evisceration underwent delayed laparoscopy, which revealed a diaphragm injury in one patient. Overall, 57 (86.4%) patients with evisceration had an intraabdominal injury that required repair.ConclusionsEvisceration should continue to prompt operative intervention. An exception can be made to a select few patients with omentum evisceration with benign abdominal findings.

An Analysis of 50 Surgically Managed Penetrating Subclavian Artery Injuries

OBJECTIVES The surgical management and outcome of penetrating subclavian artery (SCA) injuries is presented in this article. DESIGN A retrospective chart review is used to detail the management and outcome of penetrating SCA injuries. PATIENTS AND METHODS Patients with penetrating SCA injuries presenting to the Groote Schuur Hospital from January 1997 to December 2007 were reviewed. Demographic data, mechanism of injury, associated injuries, angiographic findings, surgical treatment, hospital stay, complications and mortality were noted. RESULTS Fifty patients with penetrating SCA injuries were identified from an operating trauma database. Stab and gunshot wounds accounted for 40 and 10 SCA injuries, respectively. The mean Revised Trauma Score (RTS) was 7.2. Angiography was obtained in 37 patients; false aneurysm (13) and total occlusion (nine) were the two most common findings. A median sternotomy was required in 25 (50%) patients and emergency room thoracotomy was performed in two patients (4%) for initial haemorrhage control. Primary repair of SCA injuries was possible in 52% of the patients. Three SCA injuries (6%) were ligated and one patient received an endovascular stent. Morbidity was restricted to associated brachial plexus injuries. The limb salvage rate was 100% and there were no deaths. CONCLUSION Preoperative angiography was useful in planning an operative approach. Primary repair was possible in the majority of the patients and ligation of SCA injuries was life-saving in critically ill patients.

A Ten Year Review of Civilian Iliac Vessel Injuries from a Single Trauma Centre

OBJECTIVE To report the surgical management and outcome of iliac vessel (IV) injuries in a civilian trauma centre with a high incidence of penetrating trauma. DESIGN, PATIENTS AND METHODS A retrospective record review of patients with IV injuries treated between January 2000 and December 2009. RESULTS Sixty nine patients, 59 with gunshot wounds, sustained 108 iliac vessel injuries. Mean revised trauma and injury severity scores was 7.06 and 28.4, respectively. Twenty nine patients required damage control laparotomy. Common or external iliac arteries were repaired by primary repair (10), temporary shunt with delayed graft (6), interposition graft (5) or ligation if limb non-viable (3). Forty-seven patients had injuries to the common or external iliac vein, 42 were ligated. Mortality was 25% and 6 survivors required amputation. CONCLUSIONS In a stable patient a primary arterial repair is preferred but a temporary shunt can be a life and limb saving option in the unstable patient. Ligating the common or external iliac veins is associated with a low incidence of prolonged leg swelling.

Selective Nonoperative Management in 1106 Patients With Abdominal Gunshot Wounds Conclusions on Safety, Efficacy, and the Role of Selective CT Imaging in a Prospective Single-Center Study

OBJECTIVE The primary aim of this study was to delineate the role of computed tomography (CT) in patients undergoing NOM for AGSW. BACKGROUND Nonoperative management (NOM) of abdominal gunshot wounds (AGSWs) remains controversial. METHODS This prospective study included all patients with abdominal gunshot injuries admitted to our trauma center from April 1, 2004 to September 30, 2009. Exclusion criteria included patients with peritonitis, hemodynamic instability, unreliable physical examination, head and spinal cord injury with an AGSW underwent immediate laparotomy. The remaining patients were selected for NOM. Nonperitonitic stable patients with right-sided thoracoabdominal/right upper quadrant gunshots and/or hematuria underwent mandatory CT with intravenous contrast. CT to detect missile trajectory was optional. The primary outcome measure was failure of NOM. Secondary outcomes were unnecessary laparotomy rates and mortality. RESULTS A total of 1106 patients with abdominal gunshot injuries were admitted. Of these, 834 (75.4%) underwent immediate laparotomy, whereas 272 (24.6%) were selected for NOM. In the former group, there were 56 (6.7%) deaths and 29 (3.5%) unnecessary laparotomies, whereas in the latter NOM group, 82 (30.1%) patients were managed by serial clinical examination alone, whereas 190 (69.9%) patients underwent abdominal CT scanning, in addition to serial clinical examination. The overall NOM success rate was 95.2%. Of the 13 patients undergoing delayed laparotomy, there were 10 therapeutic, 2 nontherapeutic, and 1 negative laparotomy. CONCLUSIONS The NOM of appropriately selected patients with AGSW with selective use of CT scanning is feasible, safe, and effective, but largely based on findings from serial clinical examinations.

Civilian Penetrating Axillary Artery Injuries

BackgroundThe surgical management and outcome of penetrating axillary artery (AA) injuries is presented.Patients and methodsPatients presenting to Groote Schuur Hospital with penetrating AA injuries from January 2003 to December 2009 were reviewed. Demographic data, mechanism of injury, associated injuries, angiographic findings, surgical treatment, complications, and mortality were noted.ResultsSixty-eight patients with AA injuries were identified from an operating trauma database. Stab and gunshot wounds accounted for 54 (79.4%) and 14 injuries, respectively. The mean Revised Trauma Score was 7.5 (range: 3.8–7.8). Angiography was done in 49 patients; false aneurysms (32) and total occlusions (15) were the two commonest findings. Primary repair of the injured AA was possible in 41 (60.3%) patients. Five AA (7.4%) injuries were ligated. Morbidity was restricted to associated brachial plexus injuries. The limb salvage rate was 100%.ConclusionsPrimary repair of AA injuries was possible in 60% of patients, and ligation was life-saving in critically ill patients. The associated brachial plexus injury was the cause of major long-term morbidity.

Management of a pneumopericardium due to penetrating trauma

INTRODUCTION A pneumopericardium presenting after penetrating chest trauma is a rare event. The surgical management of this clinical problem has not been clearly defined. The aim of this study was to document the mode of presentation and to suggest a protocol for management. PATIENT AND METHODS A review of a prospectively collected cardiac database of patients presenting to Groote Schuur Hospital Trauma Centre between October 2001 and February 2009 with a pneumopericardium on chest X-ray after penetrating trauma. RESULTS There were 27 patients with a pneumopericardium (mean age 25 years, range 17-36). The mechanism of injury was a stab wound to the chest in 26 patients and a single patient with multiple low velocity gunshot wounds. Six patients (22%) were unstable and required emergency surgery. One of these patients presented with a tension pneumopericardium. Twenty-one patients were initially stable. Two of these (10%) patients later developed a tension pneumopericardium within 24-h and were taken to theatre. The remaining 19 patients were managed with a subxiphoid pericardial window (SPW) at between 24 and 48h post admission. Ten of these 19 patients (52%) were positive for a haemopericardium. Only 4 of the 19 underwent a sternotomy and only two of these had cardiac injuries that had sealed. There were no deaths in this series. CONCLUSION Patients with a penetrating chest injury with a pneumopericardium who are unstable require emergency surgery. A delayed tension pneumopericardium developed in 10% of patients who were initially stable. It is our recommendation that all stable patients with a pneumopericardium after penetrating chest trauma should undergo a SPW. A sternotomy is not required in stable patients.
