Aim To review the current management, prognostic factors and outcomes of penetrating and blast injuries to the central nervous system and highlight the differences between gunshot wound, blast injury and stabbing. Methods A review of the current literature was performed. Results Of patients with craniocerebral GSW, 66–90 % die before reaching hospital. Of those who are admitted to hospital, up to 51 % survive. The patient age, GCS, pupil size and reaction, ballistics and CT features are important factors in the decision to operate and in prognostication. Blast injury to the brain is a component of multisystem polytrauma and has become a common injury encountered in war zones and following urban terrorist events. GSW to the spine account for 13–17 % of all gunshot injuries. Conclusions Urgent resuscitation, correction of coagulopathy and early surgery with wide cranial decompression may improve the outcome in selected patients with severe craniocerebral GSW. More limited surgery is undertaken for focal brain injury due to GSW. A non-operative approach may be taken if the clinical status is very poor (GCS 3, fixed dilated pupils) or GCS 4–5 with adverse CT findings or where there is a high likelihood of death or poor outcome. Civilian spinal GSWs are usually stable neurologically and biomechanically and do not require exploration. The indications for exploration are as follows: (1) compressive lesions with partial spinal cord or cauda equina injury, (2) mechanical instability and (3) complications. The principles of management of blast injury to the head and spine are the same as for GSW. Multidisciplinary specialist management is required for these complex injuries.

BackgroundIn this retrospective cohort study, we assessed the utility of laparoscopic surgery for diagnostic and therapeutic purposes in patients with anterior abdominal stab wounds (AASWs). We also investigated patient characteristics that might suggest a greater suitability of laparoscopic interventions.MethodsOver a 25-year span, we analyzed AASW patients who had operations, categorizing them based on the presence of significant intra-abdominal injuries and whether they received laparoscopic surgery or laparotomy. We compared variables such as preoperative conditions, surgical details, and postoperative outcomes. We further evaluated the criteria indicating the necessity of direct laparotomies and traits linked to overlooked injuries in laparoscopic surgeries.ResultsOf 142 AASWs surgical patients, laparoscopic surgery was conducted on 89 (62.7%) patients. Only 2 (2.2%) had overlooked injuries after the procedure. Among patients without significant injuries, those receiving laparoscopic surgery had less blood loss than those receiving laparotomy (30.0 vs. 150.0 ml, p = 0.004). Patients who underwent laparoscopic surgery also had shorter hospital stays (significant injuries: 6.0 vs. 11.0 days, p < 0.001; no significant injuries: 5.0 vs. 6.5 days, p = 0.014). Surgical complications and overlooked injury rates were comparable between both surgical methods. Bowel evisceration correlated with higher laparotomy odds (odds ratio = 16.224, p < 0.001), while omental evisceration did not (p = 0.107).ConclusionsLaparoscopy is a safe and effective method for patients with AASWs, fulfilling both diagnostic and therapeutic needs. For stable AASW patients, laparoscopy could be the preferred method, reducing superfluous nontherapeutic laparotomies.

This study discusses a tertiary trauma center's experience involving traumatic pancreatic injuries, focusing on identification, management, and complications, aiming to provide a valuable contribution to the literature on pancreatic trauma management. We conducted a five year (2019–2023) retrospective analysis utilizing trauma registry data to identified pancreatic injuries in tier 1 and 2 activations. Pancreatic Organ Injury Scaling (OIS) and overall injury severity (ISS) was assessed using AAST scoring. Data was stratified by mechanism, management, associated injuries, and outcomes. Thirty-one patients suffering firearm (48.4 ​%), stabbing (16.1 ​%), or blunt injuries (35.5 ​%) were investigated. Firearms correlated with diaphragm (P ​= ​0.047), stomach (P ​= ​0.001) and intrabdominal injury count (P = 0.0042). Robust trends were found between OIS, ISS, complication, mortality and many alike. In penetrating injury, increasing ISS and number of intrabdominal injuries should heighten pancreatic trauma suspicion and lower the threshold for surgical exploration, particularly when involving the diaphragm, stomach, transverse colon or spleen. •The majority of pancreatic injuries were missed or inconclusive on initial CT and instead were diagnosed on exploration.•In distal pancreatic resection, there was no difference in outcomes between stapled and handsewn stump closure techniques•A correlation was found between diaphragm, gastric, total intrabdominal injury count and penetrating pancreatic injury.•Penetrating pancreatic injuries have a higher incidence of morbidity and mortality than blunt pancreatic injuries.

Background Gunshot wounds to the heart are regarded as one of the most lethal penetrating injuries. There has been an increase in gunshot wounds to the chest in our institution in recent years. Injuries to the heart caused by gunshot wounds can be challenging, with patients arriving in hospital in different physiological states. We report our trauma unit’s experience with civilian gunshot wounds to the heart. Methods A retrospective review from January 2005 till December 2018 of those 18 years of age and above who presented to our hospital with penetrating cardiac injuries over eight years was done. Those who presented with a carotid pulse and a cardiac rhythm were included in the study. Blood pressure of less than 90 mmHg was considered as haemodynamic instability. Demographics, physiological parameters, injuries sustained, preferred surgical access to the chest, and type of surgery were analysed. The complications during their hospital stay and outpatient clinic were documented. The incidences of in-hospital mortality were also noted. Descriptive statistics with STATA version 15 were conducted. A p -value of < 0.05 was considered statistically significant. Results A total of 37 patients were enroled in the study; four were excluded for incomplete data. All presented directly from the scene, with a median age of 30 (IQR 24–36). Haemodynamic instability was in 64% of the cases. The most common injured chamber was the right ventricle (75.7%). There were only two complications recorded; local wound sepsis and empyema. All survivors received a post-surgical echocardiogram. The overall survival rate was 18.9% ( n  = 7). Of the ten that required emergency room thoracotomy, only one survived to discharge. Conclusion Gunshot wounds to the heart have a mortality rate greater than 80% in those arriving alive. Only one in ten of those who meet the strict criteria for emergency room thoracotomy survive hospitalisation. The local complication rate was low. Graphical Abstract

Background In penetrating abdominal trauma, computed tomography (CT) is routinely performed to evaluate stable patients for selective non-operative management (SNOM). Triple-contrast CT (oral, rectal, and IV) has traditionally been used. However, due to its disadvantages, most trauma centres, including our unit at the Charlotte Maxeke Johannesburg Academic Hospital (CMJAH), now perform single-contrast intravenous-only CT scans. We performed a retrospective review to determine the accuracy of single-contrast CT scans for detecting hollow viscus injuries (HVI) in penetrating abdominal trauma. Methods A retrospective review of all patients who presented to CMJAH with penetrating abdominal injuries was performed between 01 August 2017 and 31 August 2019 and were evaluated for SNOM with CT (IV contrast only). Patient records were reviewed to determine pertinent demographics, mechanism, and site of injury, as well as metabolic parameters. CT findings were compared to findings at laparotomy. Results A total of 437 patients met the inclusion criteria. The majority were male (92.7%), with a mean age of 31.5 yrs (SD 8.7). Injuries were predominantly due to stab wounds (72,5%, n  = 317). CT scan was negative in 342 patients, of which 314 completed SNOM successfully. A total of 93 patients proceeded to laparotomy. CT had a sensitivity of 95.1%, specificity of 44.2%, positive predictive value of 57.4%, and negative predictive value of 92%. Conclusion Single-contrast CT in penetrating abdominal trauma is a valuable investigative tool in identifying patients for SNOM. Features of HVI on single-contrast CT are not very specific and should be interpreted along with other clinical factors including wound trajectory and serial abdominal examinations. Other associated injuries such as diaphragmatic and solid organ injuries should be considered in the final management plan.

BackgroundThe management of hemodynamically stable patients with anterior abdominal stab wounds (AASW) is debated. Mini-invasive techniques using laparoscopy and non-operative management (NOM) have reduced the rate of nontherapeutic laparotomies after AASW leading to unnecessary morbidity. The aim of this study was to determine with a systematic diagnostic laparoscopy of peritoneal penetration (PP), patients who do not require abdominal exploration in the management of stable patient with an AASW.MethodsAll patients with AASW were retrospectively recorded from 2006 to 2018. Criteria of inclusion were AASW patients who underwent a systematic diagnostic laparoscopy. Criteria of exclusion were patients with an evisceration, impaling, clinical peritonitis, and hemodynamic instability. If no PP was detected, laparoscopy was terminated. If defects of peritoneum were found, a laparotomy was performed looking for diagnosis and treatment of intra-abdominal injuries.ResultsOn 131 AASW patients, 35 underwent immediate emergency laparotomy, 96 underwent diagnostic laparoscopy, 47 were positive (PP) and had an intra-abdominal exploration by laparotomy, 32 (68.1%) had intra-abdominal injuries which required treatment. All patients with an intra-abdominal injury had a positive diagnostic laparoscopy. For the 49 patients with a negative laparoscopy, the mean hospital stay was 1.6 days with ambulatory care for some patients. No patient presented a delayed injury. Non-therapeutic laparotomy rate was 15.6%. For patients who did not have an intra-abdominal injury the morbidity rate was low (3%).ConclusionOur study shows that diagnostic laparoscopy was safe, with a low duration of hospitalization, a possible ambulatory care and had an excellent ability to screen the patients who did not need a abdominal exploration. This management can avoid many unnecessary laparotomies with an acceptable rate of negative laparotomy, without any delayed diagnosis of intra-abdominal injuries and with a low morbidity rate.

Background The foley catheter balloon tamponade (FCBT) has been widely employed in the management of trauma. This study reviews our cumulative experience with the use of FCBT in the management of patients presenting with a penetrating neck injury (PNI). Methods A retrospective study was conducted at a major trauma centre in South Africa over a 9-year period from January 2012 to December 2020. All patients who presented with a PNI who had FCBT were included. Results A total of 1581 patients with a PNI were managed by our trauma centre, and 44 (3%) patients had an FCBT. Of the 44 cases of FCBT, stab wounds accounted for 93% (41/44) and the remaining 7% were for gunshot wounds. Seventy-five per cent of all FCBT (33/44) were inserted at a rural hospital prior to transfer to our trauma centre; the remaining 25% (11/44) were inserted in our resuscitation room. The success rate of FCBT was 80% (35/44), allowing further CT with angiography (CTA) to be performed. CTA findings were: 10/35 (29%) positive, 18/35 (51%) negative, and 7/35 (20%) equivocal. Fifteen patients required additional intervention (open surgery or endovascular intervention). The overall morbidity was 14% (6/44). Eighteen per cent required intensive care unit admission. The median length of stay was 1 day. The overall mortality rate was 11% (5/44). Conclusion FCBT is a simple and effective technique as an adjunct in the management of major haemorrhage from a PNI. In highly selective patients, it may also be used as definitive management.

Background Foley catheter balloon tamponade (FCBT) for bleeding penetrating neck injuries (PNIs) is effective. This study aims to audit the technique and outcomes of FCBT. Methods Adult patients with PNIs requiring FCBT presenting to Groote Schuur Hospital (GSH) within a 22-month study period were prospectively captured on an approved electronic registry. Retrospective analysis included demographics, major injuries, investigations, management and outcomes. Results During the study period, 628 patients with PNI were treated at GSH. In 95 patients (15.2%), FCBT was utilised. The majority were men (98%) with an average age of 27.9 years. Most injuries were caused by stab wounds (90.5%). The majority of catheters (81.1%) were inserted prior to arrival at GSH. Computerised tomographic angiography (CTA) was done in 92.6% of patients, while eight patients (8.4%) required catheter-directed angiography. Six were performed for interventional endovascular management. Thirty-four arterial injuries were identified in 29 patients. Ongoing bleeding was noted in three patients, equating to a 97% success rate for haemorrhage control. Thirteen (13.7%) patients required neck exploration. Seventy-two (75.8%) patients without major arterial injury had removal of the catheter at 48–72 h. Two of these bled on catheter removal. A total of 36 complications were documented in 28 patients (29.5%). There was one death due to uncontrolled haemorrhage from the neck wound. Conclusion This large series highlights the ease of use of FCBT with high rates of success at haemorrhage control (97%). Venous injuries and minor arterial injuries are definitively managed with this technique.

This study reviews our cumulative experience with the management of patients presenting with a retained knife following an abdominal stab wound (SW). A retrospective study was conducted at a major trauma centre in South Africa over a 15-year period from July 2006 to December 2020 including all patients who presented with a retained knife in the abdomen following a SW. A total of 42 cases were included: 37 males (93%) with a mean age of 26 years. A total of 18 knives (43%) were in the anterior abdomen and 24 were posterior abdomen. Plain radiography was performed in 88% (37/42) of cases and computed tomography was performed in 81% (34/42); 90% (38/42) underwent extraction in the operating theatre. Laparotomy was performed in 62% (26/42). Of all the laparotomies performed, 77% (20/26) were positive for intra-abdominal organ or visceral injury. Overall morbidity was 31%. There were two mortalities (5%). Laparotomy was less commonly required for the posterior abdomen (33% (8/24) vs 100% (18/18), <0.001). For retained knives in the anterior abdomen, 72% (13/18) of the laparotomies were positive for intra-abdominal organ or visceral injury. For the posterior abdomen, 7 of the 8 (88%) were positive for intra-abdominal organ or visceral injury. There were no differences in the need for intensive care unit admission, length of hospital stay, morbidities or mortalities. Uncontrolled extraction of a retained knife in the abdomen outside of the operating theatre must be avoided. Retained knives in the anterior abdomen usually require formal laparotomy, but this is generally not required for posterior abdomen.

Background Debate remains regarding the optimum role of laparoscopy in the setting of trauma although it can offer advantages over traditional exploratory laparotomy. Laparoscopy can be a screening, diagnostic or therapeutic tool in trauma. The purpose of this review is to evaluate the role of laparoscopy in penetrating abdominal trauma Methods The PUBMED database was searched with the keywords “Laparoscopy AND Trauma”. Additional citation searching and searching of the grey literature was conducted. Relevant studies were chosen on the basis of the defined inclusion and exclusion criteria and quality was assessed where appropriate using the Downs and Black checklist Results In total, 51 studies were included in the analysis of which only 13 were prospective. In most studies, laparoscopy was used as a screening, diagnostic or therapeutic tool. In total, 2569 patients underwent diagnostic laparoscopy (DL) for penetrating abdominal trauma (PAT), 1129 (43.95 %) were positive for injury. 13.8 % of those with injury had a therapeutic laparoscopy. In total 33.8 % were converted to laparotomy, 16 % of which were non-therapeutic and 11.5 % of them were negative. 1497 patients were spared a non-therapeutic laparotomy. Overall, 72 patients suffered complications, there were 3 mortalities and 83 missed injuries. Sensitivity ranged from 66.7–100 %, specificity from 33.3–100 % and accuracy from 50–100 %. 23 of the 50 studies reported sensitivity, specificity and accuracy of 100 %, including the four most recent studies. In general the quality of the reported studies was poor. When used for cohort studies, the mean Downs and Black checklist score was 13.25 out of a possible total of 28. Conclusions In summary, laparoscopy in PAT may have an important role in a selected subgroup of patients, with surgeon expertise also an important factor. Laparoscopy has screening, diagnostic and therapeutic roles, particularly where diaphragm injury is suspected. It is extremely sensitive in determining need for laparotomy but detects hollow visceral injuries less reliably. It has potential as a therapeutic tool in centres with appropriate expertise. The development of specific guidelines or protocols may increase the value of laparoscopy in trauma but this would require more evidence of a higher quality.
