Screening helical computed tomographic scanning in haemodynamic stable patients with transmediastinal gunshot wounds.
AIM: The purpose of this study was to review and evaluate the efficacy of contrast-enhanced helical computed tomographic (CT) scanning in evaluating potential mediastinal injuries in stable patients with transmediastinal gunshot wounds (TMGSWs). METHODS: During the review period, 01 January 2002-31 May 2005, the medical records of all haemodynamically stable patients with TMGSWs were retrieved and reviewed for demographics, diagnostic workup, treatment and complications. Screening CT was considered inconclusive in the presence of a mediastinal haematoma, pneumomediastinum or a missile track in proximity of major mediastinal structures. Inconclusive CT scans were further evaluated with angiography, and/or oesophography, and/or cardiac ultrasound. RESULTS: Fifty consecutive haemodynamically stable patients with TMGSWs were identified. Thirty-five CT scans were performed, of which 29 (82.9%) were conclusive. Further diagnostic evaluation in the remaining six patients showed no injury. All patients were observed in a high-care unit and there were no missed injuries. The hospital charges generated with the CT scan based protocol were significantly less than with standard evaluation. CONCLUSION: Contrast enhanced helical CT scanning is a safe, efficient and cost effective screening tool for evaluating haemodynamically stable patients with TMGSWs.

Civilian duodenal gunshot wounds: surgical management made simpler.
INTRODUCTION: Low-velocity gunshot wounds cause most civilian duodenal injuries. The objective of this study was to describe a simplified surgical algorithm currently in use in a South African civilian trauma center and to verify its validity by measuring morbidity and mortality. METHODS: A retrospective chart review of patients with duodenal gunshot injuries during the study period January 1999 to December 2003 was performed. Data points accrued included patient demographics, admission hemodynamic status and resuscitative measures, laparotomy damage control procedures, methods of surgical repair of the duodenal injury, associated injuries, length of intensive care and hospital stays, complications, and mortality. RESULTS: A total of 75 consecutive patients with gunshot injuries to the duodenum were reviewed. Primary repair was performed in 54 patients (87%), resection and reanastomosis in 7 (11%), and pancreatoduodenectomy in 1 (2%) during the initial phases. The overall morbidity and mortality were 58% and 28%, respectively. Duodenum-related complications were recorded in nine (15%) patients: two duodenal fistulas, one duodenal obstruction, and six cases of suture-line dehiscence. Overall and duodenum-related morbidity rates in patients with combined pancreatoduodenal injuries were 83% and 17%, respectively. Duodenum-related mortality occurred in three (4.8%) patients. CONCLUSIONS: Most civilian low-velocity duodenal gunshot injuries treated with simple primary repair result in overall morbidity, mortality, and duodenum-related complication rates comparable to those in reports where more complex surgical procedures were employed. Primary repair is also applicable for most combined pancreatic and duodenal gunshot injuries.

Video-assisted thoracoscopic pericardial window for penetrating cardiac trauma.
OBJECTIVE: To report our experience with thoracoscopic pericardial window (TPW) for occult penetrating cardiac injury. PATIENTS AND METHODS: During the study period (1 January - 31 December 2000), a small group of haemodynamically stable patients with anterior left-sided praecordial wounds were selected for TPW. All patients underwent general anaesthesia with double-lumen intubation and collapse of the left lung. A rigid laparoscope was inserted through a 2 cm incision in the 5th intercostal space in the anterior axillary line. Another 3 cm incision was made in the fourth intercostal space over the cardiac silhouette. Conventional instruments were used to grasp and open the pericardium. Any myocardial injury identified was an indication to proceed to sternotomy. In the absence of a myocardial injury and bleeding, the procedure was terminated and considered therapeutic. RESULTS: Seventy-one patients with suspected penetrating cardiac injuries were seen. TPW was successfully completed in 13 patients. All were men, with a mean age of 29.8 (range 19 - 38) years. Ten and 3 patients sustained stab and gunshot wounds, respectively. The mean revised trauma score was 7.84. Ultrasound was performed in 12 patients; the results were equivocal for 2 patients, and positive for an effusion in 4 patients. Haemopericardium was found in 3 patients, 2 of whom proceeded to sternotomy. No cardiac injury was found in 1, a left ventricular contusion was identified in the second, and the third patient had no further procedure after good video-thoracoscopic visualisation of the anterior myocardium revealed no injury. In another patient, pericardial bruising was evident without any haemopericardium. The mean operative time was 13.4 (range 10 - 15) minutes, with a mean hospital stay of 5.4 (range 3 - 8) days. There were no complications. The use of a double-lumen endotracheal tube increased the cost of TPW by 23% when compared with subxiphoid pericardial window (SPW). CONCLUSION: TPW is a feasible, although in our setting not cost-effective, diagnostic option for occult penetrating cardiac injuries.

Haemopericardium in stable patients after penetrating injury: is subxiphoid pericardial window and drainage enough? A prospective study.
AIM: This prospective study was undertaken to evaluate whether stable patients with haemopericardium could safely be managed with subxiphoid pericardial window (SPW) and drainage only. PATIENTS AND METHODS: From July to December 2001, all stable patients with haemopericardium diagnosed by SPW, who did not have immediate active bleeding, were subjected to sternotomy to grade the injury using the American Association for the Surgery of Trauma (AAST)-cardiac injury score. The data of all patients with penetrating cardiac injuries for the year 2001 is presented to place into perspective the spectrum of cardiac injuries seen. RESULTS: Fourteen patients qualified for inclusion into the study. Ten (71.4%) patients had Grade I-III cardiac injuries. These could have safely been managed by SPW and drainage alone. The remaining four patients with Grade IV injuries showed no active bleeding at the time of sternotomy. During the first half of the year, seven patients diagnosed with haemopericardium were managed with SPW and drainage only. These seven patients showed no procedure-related complications and were well at 2-week follow-up. Ten patients presented with acute cardiac tamponade. There was a single death in the latter group. CONCLUSION: This preliminary prospective study, though limited by small numbers, shows that 10/14 (71%) of stable patients with haemopericardium had unnecessary non-therapeutic sternotomy and could have safely been managed with SPW and drainage only. Further prospective, randomised studies are required to confirm the good outlook.

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.

Thoracoscopic evacuation of retained posttraumatic hemothorax.
BACKGROUND: Residual posttraumatic hemothoraces occur in 1% to 20% of patients managed with tube thoracostomy. Video-assisted thoracoscopic surgery (VATS) has emerged as an alternative to thoracotomy to evacuate these retained collections. This report reviews a recent trauma unit experience with thoracoscopic evacuation of hemothoraces. METHODS: The records of all trauma patients undergoing surgical intervention for retained hemothoraces over the 30-month period January 2001 to June 2003 were reviewed. RESULTS: The study included 46 patients. All sustained penetrating injuries, 40 with stab and 6 with gunshot wounds. Twenty-two, 17, and 7 patients each had one, two and three attempts at drainage with tube thoracostomy, respectively. In 37 patients (80%), retained infected/uninfected pleural fluid was successfully evacuated thoracoscopically. VATS failed in 9 (20%) patients and the procedure was converted to open thoracotomy. Dense adhesions were present in all 9 of these patients. The mean time interval between injury and thoracoscopy and thoracotomy, was 13.3 days (range 3-46 days) and 14.5 days (range 11-24 days), respectively. The mean volume of pleural fluid evacuated thoracoscopically was 650 mL. The failure of VATS evacuation correlated with the empyema rate. The median postoperative stay was 5 days for both groups. CONCLUSIONS: Video-assisted thoracoscopic surgery is an accurate, safe, and reliable operative therapy for retained posttraumatic pleural collections, even in patients presenting later than the conventionally accepted 3- to 5-day window from the time of injury.

Laparoscopy-assisted repair of diaphragm injuries.
In this study we review our experience with an alternative laparoscopy-assisted technique for repair of diaphragm injuries. All patients admitted with an isolated diaphragm injury who underwent laparoscopy-assisted repair between January 1996 and February 2000 were included in the study. The diagnosis of the diaphragm injury was either obvious, with omentum herniating through the chest wall, or occult with confirmation of the injury at laparoscopy. Repair of the diaphragm was performed using standard surgical instruments via a 4-cm subcostal incision with use of abdominal wall traction and the laparoscope for visualization of the defect. A total of 24 patients underwent successful laparoscopy-assisted repair; There were twenty men and four women with an average age of 28.8 years (range 23-49 years). The average Revised Trauma score was 12. There were 23 grade II and 2 grade III diaphragm injuries. The mean operative time was 61 minutes (range 25-120 minutes) and the average hospital stay from the time of surgery to the time of discharge was 2.29 days (range 1-4 days). The procedure failed in one patient as a result of gaseous distension of the bowel. One patient developed a tension pneumothorax, and two others developed atelectasis. Laparoscopic-assisted repair of isolated diaphragm injuries using abdominal wall traction and standard surgical instruments is a feasible option with minimal morbidity and no mortality.
