A decade long overview of damage control laparotomy for abdominal gunshot wounds.

PURPOSE: Over the last three decades, damage control laparotomy (DCL) has become important in the management of abdominal gunshot wounds (GSW). This paper reviews the experience of a single institution over a decade with the use of DCL for GSW of the abdomen. METHODS: Longitudinal data (2013-2022) was collected from the Hybrid Electronic Medical Registry database to identify all patients with an abdominal GSW over the study period. The data was stratified based on patients who underwent DCL and those who did not. Descriptive analysis was completed to summarise the raw data. Univariate and multivariate analysis was completed to identify variables associated with undergoing DCL. RESULTS: There were 135 patients (32%) who underwent DCL and 290 patients (68%) who did not. Colonic, small bowel, mesenteric, hepatic, pancreatic and intra-abdominal vessel injuries were associated with the need for DCL (P<0.05). In total, 85 of the 135 (63%) patients who underwent DCL required more than one damage control technique. There were 45 (33%) mortalities in the DCL group compared to 16 mortalities (6%) in the non-DCL group (P<0.001). CONCLUSION: One third of patients who underwent a laparotomy following a gunshot wound to the abdomen had a DCL. The indications for DCL include both physiological criteria and injury patterns. DCL is associated with significant morbidity and mortality. Efforts need to be directed towards refining the indications for DCL in this group of patients to prevent inappropriate application of this potentially lifesaving technique.

Point of care ultrasound and sub-xiphoid window reduce uncertainty in the management of potential dual-cavity injuries in patients with torso stab wounds.

INTRODUCTION: This paper reviews our experiences with the management of patients with torso stab wounds and potential injuries in both the chest and abdomen over the last decade. The aim of the project is to clarify our approach and provide an evidence base for clinical algorithms. We hypothesize that there is room for our clinical algorithms to be further refined in order to address the diverse, life threatening injuries that can result from stab wounds to the torso. METHODS: Patients with one or more torso stab wounds, and a potential injury in both the chest and the abdomen were identified from a local database for the period December 2012 to December 2020. RESULTS: A total of 899 patients were identified. The mean age was 29 years (SD = 9) and 93% of patients were male. Amongst all patients, 686 (76%) underwent plain radiography, 207 (23%) a point of care ultrasound assessment, and 171 (19%) a CT scan. Following initial resuscitation, assessment and investigation, a total of 527 (59%) patients proceeded to surgery. A total of 185 patients (35%) underwent a semi elective diagnostic laparoscopy to exclude an occult diaphragm injury. Of the 342 who underwent an emergency operation, 9 patients (1%) required thoracotomy or sternotomy exclusively, 299 patients (33%) required a laparotomy exclusively and 34 patients (4%) underwent some form of dual cavity exploration. In total, there were 16 deaths, a mortality rate of 2%. The use of laparoscopy, point of care ultrasound and subxiphoid pericardial window increased over the period of this study. CONCLUSIONS: Patients with torso stab wounds and potential injuries above and below the diaphragm are challenging to manage. The highly structured clinical algorithm of the ATLS course should be complemented by the use of point of care ultrasound and sub-xiphoid window to assess the pericardium. These adjuncts reduce the likelihood of negative exploration and incorrect operative sequencing.

AAST grade of liver injury is not the single most important consideration in decision making for liver trauma.

BACKGROUND: The liver is one of the most injured organs in both blunt and penetrating trauma. The aim of this study was to identify whether the AAST liver injury grade is predictive of need for intervention, risk of complications and mortality in our patient population, and whether this differs between blunt and penetrating-trauma mechanisms. METHODS: Retrospective review of all liver injuries from a single high-volume metropolitan trauma centre in South Africa from December 2012 to January 2022. Inclusion criteria were all adults who had sustained traumatic liver injury. Patients were excluded if they were under 15 years of age or had died prior to operation or assessment. Statistical analysis was undertaken using both univariate and multivariate models. RESULTS: 709 patients were included, of which 351 sustained penetrating and 358 blunt trauma. Only 24.3 % of blunt compared to 76.4 % of penetrating trauma patients underwent laparotomy (p< 0.001). In blunt trauma, increasing AAST grade correlated directly with rates of laparotomy with an odds ratio of 1.7 (p < 0.001). In penetrating trauma, there was no statistical significance between increasing AAST grade and the rate of laparotomy. The rate of bile leak was 4.5 % (32/709) and of rebleed was 0.7 % (5/709). Five patients underwent ERCP and endoscopic sphincterotomy for bile leak, and three required angio-embolization for rebleeding. Increasing AAST grades were significantly associated with the odds of bile leak in both blunt and penetrating trauma. There was a statistically significant increase in the odds of a rebleed with increasing AAST grade in penetrating trauma. Five patients rebled, of which three died. Seven patients developed hepatic necrosis. Seventy-six patients died (10 %). There were 34/358 (9 %) deaths in the blunt cohort and 42 /351 (11 %) deaths in the penetrating trauma cohort. CONCLUSION: AAST grade in isolation is not a good predictor of the need for operation in hepatic trauma. Increasing AAST grade was not found to correlate with increased risk of mortality for both blunt and penetrating hepatic trauma. In both blunt and penetrating trauma, increasing AAST grade is significantly associated with increased bile leak. The need for ERCP and endoscopic sphincterotomy to manage bile leak in our setting is low. Similarly, the rate of rebleeding and of angioembolization was low.

Broad Responses and Attitudes to Having Music in Surgery (The BRAHMS Study): An Australia and Aotearoa New Zealand Perspective.

Background: Surgery is a stressful exercise, and the experience of occupational stress may have impacts on surgical performance, and surgeon well-being. Music is played in operating theatres (OTs) throughout the world, and while it may improve surgical performance, and reduce clinician stress within the OT, concerns exist over its distracting and noise-creating properties. Methods: In this prospective observational study, between May to August 2022, Vascular, General and Paediatric surgeons and registrars in Australia and Aotearoa New Zealand (AoNZ) responded to a survey investigating the way they use music, and their perceptions and attitudes towards its effect on the OT environment. Binomial logistic regression and Chi squared tests of association were performed, accepting p < 0.05 as significant. Results: In this cohort of 120 surgeons, 45 % were vascular specialists, 30 % were female and 59 % were consultant surgeons. The most commonly preferred music genres were easy listening and pop. Over 75 % of surgeons enjoyed having music in their OTs with the majority reporting it improved their temperament, how mentally fatiguing a procedure felt and how anxious or stressed they felt. Vascular surgeons were more likely to believe music had a positive influence on communication than their general and paediatric surgery colleagues (p < 0.01). Registrars had significantly higher odds of believing music had a positive effect on their temperament, and how stressed and anxious they felt when operating, when compared to consultants (p < 0.05). Conclusions: This study provides a window into the surgeons' use of and attitudes towards intra-operative background music and its effect on stress and cognitive load in Australia and AoNZ. While overall, music is viewed positively by this cohort, there was some difference seen across specialties and level of experience. Further subjective and objective data in this field may provide useful information to guide hospital policy and inform pathways for clinician wellbeing.

Management of thoracoabdominal gunshot wounds - Experience from a major trauma centre in South Africa.

INTRODUCTION: The management of thoracoabdominal (TA) gunshot wounds (GSW) remains challenging. This study reviewed our experience with treating such injuries over a decade. MATERIALS AND METHODS: A retrospective study was conducted at a major trauma centre in South Africa over a ten-year period from December 2012 to January 2022. RESULTS: Two hundred sixteen cases were included (male: 85 %, mean age: 33 years). Median RTS: 8 and median ISS: 17 (IQR: 10-19). The mean value of physiological parameters: Heart Rate (HR): 98/min, Systolic Blood Pressure (SBP): 119 mmHg, Temperature (T): 36.2 °C, pH: 7.35, Lactate 3.7 mmol/l. Ninety-nine (46 %) underwent a CT scan of the torso. One hundred fifty-four cases (69 %) were managed operatively: thoracotomy only [5/154 (3 %)], laparotomy only [143/154 (93 %)], and combined thoracotomy and laparotomy [6/154 (4 %)]. Those who had surgery following preoperative CT had a lower rate of dual cavity exploration (2 % vs 4 %, p = 0.51), although it did not reach statistical significance. The overall morbidity was 30 % (69). 82 % required intensive care (ICU) admission. The mean length of hospital stay was 14 days. The overall mortality was 13 % (28). Over the 10-year study period, there was a steady increase in the number of cases of TA GSWs managed at our institution. Over the study period, an increasing use of CT was noted, along with a steady reduction in the proportion of operations performed. CONCLUSIONS: Thoraco-abdominal GSWs remain challenging to manage and continue to be associated with significant morbidity and mortality. The increased use of CT scans has reduced the degree of clinical confusion around which body cavity to prioritize, leading to an apparent decrease in dual cavity exploration, and has allowed for the increased use of minimalistic and non-operative approaches.

Laparotomy for Abdominal Stab Wound With Combined Omental and Organ Evisceration: 10-Year Experience From a Major Trauma Centre in South Africa.

INTRODUCTION: Combined omental and organ evisceration following anterior abdominal stab wound (SW) is uncommon and there is a paucity of literature describing the management and spectrum of injuries encountered at laparotomy. METHODS: A retrospective study was undertaken on all patients who presented with anterior abdominal SW involving combined omental and organ evisceration who underwent laparotomy over a 10-year period from January 2008 to January 2018 at a major trauma centre in South Africa. RESULTS: A total of 61 patients were eligible for inclusion and all underwent laparotomy: 87% male, mean age: 29 years. Ninety-two percent (56/61) had a positive laparotomy whilst 8% (5/61) underwent a negative procedure. Of the 56 positive laparotomies, 91% (51/56) were considered therapeutic and 9% (5/56) were non-therapeutic. In addition to omental evisceration, 59% (36/61) had eviscerated small bowel, 28% (17/61) had eviscerated colon and 13% (8/61) had eviscerated stomach. A total of 92 organ injuries were identified. The most commonly injured organs were small bowel, large bowel and stomach. The overall complication rate was 11%. Twelve percent (7/61) required intensive care unit admission. The mean length of hospital stay was 9 days. The overall mortality rate for all 61 patients was 2%. CONCLUSIONS: The presence of combined omental and organ evisceration following abdominal SW mandates laparotomy. The small bowel, large bowel and stomach were the most commonly injured organs in this setting.

The "weekend effect" does not impact on outcome of trauma laparotomy - Experience from a level 1 trauma centre in New Zealand.

PURPOSE: Trauma centres have been proven to provide better outcomes in developed countries for overall trauma, but there is limited literature on the systematic factors that describe any discrepancies in outcomes for trauma laparotomies in these centres. This study was conducted to examine and interrogate the effect of systematic factors on patients undergoing a trauma laparotomy in a developed country, intending to identify potential discrepancies in the outcome. METHODS: This was a retrospective study of all laparotomies performed for trauma at a level 1 trauma centre in New Zealand. All adult patients who had undergone an index laparotomy for trauma between February 2012 and November 2020 were identified and laparotomies for both blunt and penetrating trauma were included. Repeat laparotomies and trauma laparotomies in children were excluded. The primary clinical outcomes reviewed included morbidity, length of hospital stay, and mortality. All statistical analysis was performed using R v.4.0.3. RESULTS: During the 9-year study period, 204 trauma laparotomies were performed at Waikato hospital. The majority (83.3%) were performed during office hours (170/204), and the remaining 16.7% were performed after hours (34/204). And 61.3% were performed on a weekday (125/204), whilst 38.7% were performed on the weekend/public holiday (79/204). Most of the parameters in office hours and after hours groups had no statistically significant difference, except lactate (p = 0.026). Most of the variables in weekday and weekend groups had no statistically significant difference, except pH, lactate, length of stay, and gastrointestinal complications (p = 0.012, p < 0.001, p = 0.003, p = 0.020, respectively). CONCLUSION: The current trauma system at Waikato hospital is capable of delivering care for trauma laparotomy patients with the same outcome regardless of working hours or after hours, weekday or weekend. This confirms the importance of a robust trauma system capable of responding to the sudden demands placed on it.

Double Jeopardy Injuries: Improved Clinical Outcomes With FAST Imaging and Subxiphoid Pericardial Window for Combined Cardiac and Abdominal Stab Wounds.

BACKGROUND: This study reviews our experience with combined cardiac and abdominal stab wounds over 12 years and reviews how changes in technology and clinical approaches have impacted our management of these patients. MATERIALS AND METHODS: A retrospective cohort study was conducted from January 2008 to January 2020 at a major trauma centre in South Africa. All patients with concurrent SWs to the chest and the abdomen and required both a thoracotomy for cardiac injury and a laparotomy for an intra-abdominal injury at the same setting were included. RESULTS: Twenty-two cases were identified (100% male, mean age: 27 years). Mean values of admission physiology: systolic blood pressure (SBP): 85 mmHg, pH: 7.2, base excess: -10.2 mmol/L and serum lactate 6.7 mmol/L. Thirty-two percent (7/22) of cases underwent a Focused Assessment with Sonography in Trauma (FAST) scan (5 positive and 2 negative). All 7 cases had intraoperatively confirmed cardiac injuries. The thoracotomy first approach was used in 18 cases (82%), and the laparotomy first approach was used in the remaining 4 cases (18%). Nineteen (86%) of the 22 laparotomies were positive. A total of 6 patients (27%) experienced one or more complications. The mean length of hospital stay was 9 days. The overall mortality was 18% (4/22) and all mortality occurred prior to 2013. DISCUSSION: Double jeopardy is still associated with an increased risk of mortality. The use of FAST and Subxiphoid Pericardial Windows (SPWs) have reduced clinical uncertainty, decreasing the need for concomitant thoracotomy and laparotomy to be performed.

Penetrating buttock trauma is morbid but rarely fatal - A South African experience.

BACKGROUND: Penetrating injuries to the buttock are relatively rare but are associated with significant morbidity. This study aimed to review our experience in managing penetrating trauma to the buttocks to contextualize the injury, document the most common associated injuries, and generate an algorithm to assist with the management of these patients. METHODS: A retrospective study was conducted at a major trauma center in South Africa over 8 years (January 2012 to January 2020). All patients presenting with a penetrating buttock injury were included. RESULTS: Our study included 40 patients. Gunshot wounds accounted for 93% (37/40), stab wounds accounted for 5% (2/40), and 1 case was gored by a cow. The majority (98%) underwent further investigation in the form of imaging or endoscopy. Forty percent (16/40) required surgical intervention. Of these 16 cases, 14 required a laparotomy, and 2 required gluteal exploration. Fifty-six percent (9/16) required a stoma. Five percent (2/40) experienced one or more complications, both of whom had stomas. The median length of stay for all patients was 3 days, whereas for the patients with stomas was 7 days. There were no ICU admissions or mortality in this study. Only 3 of the 9 stomas were reversed, and the median time to reversal was 16 months. CONCLUSION: Penetrating trauma to the buttock may result in injuries to surrounding vital structures, which must be actively excluded. Rectal injury was the most common injury, and most required a defunctioning colostomy as part of the management resulting in significant morbidity.

Foley Catheter Balloon Tamponade for Actively Bleeding Wounds Following Penetrating Neck Injury is an Effective Technique for Controlling Non-Compressible Junctional External Haemorrhage.

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.

Trends in the Management of Abdominal Gunshot Wounds Over the Last Decade: A South African Experience.

BACKGROUND: This study aimed to review our decade-long experience with the management of abdominal gunshot wounds (GSWs), to document trends in our approach and to develop an evidence base for our contemporary management algorithms in a major trauma in South Africa. MATERIALS AND METHODS: This was a retrospective study that included all adult patients with abdominal GSWs between January 2013 and October 2020 managed at a major trauma centre in South Africa. RESULT: Five hundred and ninety-six cases were included (87% male, mean age: 32 years). The median Injury Severity Score (ISS) was 12. 52% (309/596) of cases had indications of immediate laparotomy and proceeded directly to the operating room without any CT imaging. Of this cohort, the laparotomy was positive in 292 and in the remainder (5%) was negative. Of the remaining 287 cases, 209 underwent a CT scan (35%). 78 were managed without any CT imaging. Of the 78 who did not undergo CT scan, all were managed without any operation and discharged home well. Of the 209 who underwent CT scan, 99 were observed and only one case in this group subsequently required a laparotomy. The remaining 110 cases underwent a laparotomy, which was negative in 7. There were correlations with increasing use of CT, as well as a decrease in those proceeding directly to laparotomy. The overall morbidity rate was 8% (47/596). 32% (190/596) require intensive care unit (ICU) admission. The overall mortality rate was 8% (67/596). CONCLUSIONS: The management of abdominal GSWs has continued to evolve. There is now a well-defined role for selective non-operative management in this group of patients and relies on accurate CT assessment. CT scan is now an important component in the management of abdominal GSW even in our resource-constrained environment.

Trends in Adoption of Laparoscopic Appendicectomy in a Developing Country: Closing the Gap.

BACKGROUND: This study reviews our use of laparoscopic versus open appendicectomy over the last decade to track the trends in their usage in a middle-income country. METHODS: A retrospective study was conducted on patients with intraoperative confirmed acute appendicitis from January 2013 to December 2019 at Grey's Hospital, Pietermaritzburg, South Africa. RESULTS: Eight hundred fifty-one cases of AA were included. 724 (85%) patients underwent open surgery; 435 (60%) via a midline incision and 194 (27%) via a local incision. 127 (15%) patients underwent laparoscopic appendicectomy. A significant rend was noted for an increasing proportion of surgery performed by laparoscopy compared to open surgery (p = 0.02). Patients who underwent open surgery compared to laparoscopy presented with greater peritonism (48.5% vs. 28%, p < 0.001), delay from symptom onset (3 vs. 2 days, p < 0.001), more frequently from rural areas (94% vs. 86%, p = 0.002) and with higher AAST scores (46.7% AAST ≥ 4, vs. 14.9%, p < 0.001). This former group had significantly greater morbidity (42% vs. 35%, p < 0.001) with higher Clavien-Dindo scores, were more likely to require ICU admission (8.3% vs. 2.3%, p < 0.001) and have longer hospital stay (4 days vs. 2 days, p < 0.001); no statistically significant difference in mortality was observed (1.1% vs. 0.8%, p = 0.75). CONCLUSIONS: There has been a steady increase in the uptake of laparoscopic appendicectomy and decrease in open approaches in our centre. There is still a high rate of patients with advanced disease, and it is unlikely that this cohort will be suitable for laparoscopic surgery. If we hope to increase the uptake of laparoscopic surgery for acute appendicitis even further, we must focus on identifying patients with early and low-grade disease.

WSES/GAIS/WSIS/SIS-E/AAST global clinical pathways for patients with skin and soft tissue infections.

Skin and soft-tissue infections (SSTIs) encompass a variety of pathological conditions that involve the skin and underlying subcutaneous tissue, fascia, or muscle, ranging from simple superficial infections to severe necrotizing infections.Together, the World Society of Emergency Surgery, the Global Alliance for Infections in Surgery, the Surgical Infection Society-Europe, The World Surgical Infection Society, and the American Association for the Surgery of Trauma have jointly completed an international multi-society document to promote global standards of care in SSTIs guiding clinicians by describing reasonable approaches to the management of SSTIs.An extensive non-systematic review was conducted using the PubMed and MEDLINE databases, limited to the English language. The resulting evidence was shared by an international task force with different clinical backgrounds.

The Management of Penetrating Neck Injury With Retained Knife: 15-Year Experience From a Major Trauma Center in South Africa.

BACKGROUND: This study reviews our cumulative experience with the management of patients presenting with a retained knife following a penetrating neck injury (PNI). METHODS: A retrospective cohort study was conducted at a major trauma center in South Africa over a 15-year period from July 2006 to December 2020. All patients who presented with a retained knife in the neck following a stab wound (SW) were included. RESULTS: Twenty-two cases were included: 20 males (91%), mean age: 29 years. 77% (17/22) were retained knives and 23% (5/22) were retained blades. Eighteen (82%) were in the anterior neck, and the remaining 4 cases were in the posterior neck. Plain radiography was performed in 95% (21/22) of cases, and computed tomography (CT) was performed in 91% (20/22). Ninety-five percent (21/22) had the knife or blade extracted in the operating room (OR). Formal neck exploration (FNE) was undertaken in 45% (10/22) of cases, and the remaining 55% (12/22) underwent simple extraction (SE) only. Formal neck exploration was more commonly performed for anterior neck retained knives than the posterior neck, although not statistically significant [56% (10/18) vs 0% (0/18), P = .096]. There were no significant differences in the need for intensive care admission, length of hospital stay, morbidities, or mortalities between anterior and posterior neck retained knives. DISCUSSION: Uncontrolled extraction of a retained knife in the neck outside of the operating room may be dangerous. Retained knives in the anterior neck commonly required formal neck exploration but not for posterior neck retained knives.

In-Hospital Mortality Following Traumatic Injury in South Africa.

Trauma is a leading cause of death worldwide and in South Africa. We aimed to quantify the in-hospital trauma mortality rate in Pietermaritzburg, South Africa. Background: The in-hospital trauma mortality rate in South Africa remains unknown, and it is unclear whether deficits in hospital care are contributing to the high level of trauma-related mortality. Methods: All patients hospitalized because of trauma at the Department of Surgery at Grey's Hospital, Pietermaritzburg Metropolitan Trauma Service, were prospectively entered in an electronic database starting in 2013 and the data were retrospectively analyzed. The trauma service adheres to Advanced Trauma Life Support and the doctors have attended basic and advanced courses in trauma care. The primary outcome was in-hospital mortality. Results: Of 9795 trauma admissions, 412 (4.2%) patients died during hospital care between January 2013 and January 2019. Forty-six percent died after road traffic accidents, 19% after gunshot wounds, 13% after stab wounds, and 10% after assaults. Sixteen percent were classified as avoidable deaths due to inappropriate care and resource limitations. Fifty percent died because of traumatic brain injury and 80% of them were unavoidable. Conclusions: In conclusion, the in-hospital trauma mortality rate at a South African trauma center using systematic trauma care is lower than that reported from other trauma centers in the world during the past 20 years. Nevertheless, 16% of death cases were assessed as avoidable if there had been better access to intensive care, dialysis, advanced respiratory care, blood for transfusion, and improvements in surgery and medical care.

Penetrating colonic trauma and damage control surgery: Anastomosis or stoma?

BACKGROUND: The management of colon injuries in damage control surgery (DCS) remains controversial. METHODS: A retrospective study investigating outcomes of penetrating colonic trauma in patients who survived beyond the initial repeat laparotomy (IRL) after DCS was performed. Patients over 18 years with penetrating colon injury and who underwent DCS from 2012 to 2020 were included from our electronic trauma registry. Demographic data, admission physiology and Injury Severity Score (ISS) were reviewed. Patients were classified into three groups: primary repair of non-destructive injuries at DCL, delayed anastomosis of destructive injuries at IRL and diversion of destructive injuries at IRL. Outcomes observed included leak rates, length of intensive care unit stay, length of hospital stay, morbidities, mortality and colon-related mortality. RESULTS: Out of 584 patients with penetrating colonic trauma, 89 (15%) underwent DCS. After exclusions, 74 patients were analysed. Mean age was 32.8 years (SD 12.5); 67 (91%) were male. Mechanism of injury was gunshot in 63 (85%) and stab 11 (15%) patients. Seventeen patients underwent primary repair at DCS, of which one leaked. Twenty patients underwent delayed anastomosis at IRL. Of these, five (25%) developed leaks. Mortality was significantly higher for those with an anastomotic leak compared to those without (p < 0.001). Thirty-seven patients were diverted at IRL. Overall mortality (p = 0.622) and colon-related mortality (p = 0.592) were not significantly different across groups. CONCLUSION: Delayed anastomosis at IRL following DCL was associated with a leak rate of 25% in this study. When anastomotic leak did occur, it was associated with significant mortality. Delayed anastomosis should only be undertaken in highly selected patients.

Recurrent pneumothorax following chest tube removal in thoracic stab wounds: a comparative study between end inspiratory versus end expiratory removal techniques at a major trauma centre in South Africa.

BACKGROUND: Tube thoracostomy (TT) insertion is a commonly performed procedure in trauma that is standardised, but the optimal removal technique based on the timing in relation to the respiratory cycle remains controversial. METHODS: A prospective study was undertaken at a major trauma centre in South Africa over a 4-year period from January 2010 to December 2013, and included all patients with pneumothorax secondary to thoracic stab wounds. TTs were removed by either end of inspiration technique (EIT) or end of expiration (EET) technique and the rate of recurrent pneumothorax (RPTX) following removal was compared. We hypothesized that there is no difference in the rate of RPTX between the end inspiratory (EI) and end expiratory (EE) removal technique. RESULTS: A total 347 patients were included. Of the 184 TTs removed by EIT, there were 17 (9%) RPTXs. Of the 163 with EET, there were 11 RPTXs (7%), (9% versus 7%, chi-squared, P = 0.395). Of the total 28 (9%) patients with RPTXs following removal of chest tubes, two (7%) required reinsertion of chest tube (0.5% (1/184) in EIT and 0.6% (1/163) in EET, P = 0.747). CONCLUSIONS: Timing of TT removal in relation to the respiratory cycle does not appear to influence the incidence of RPTX in patients with thoracic stab wounds. Technique of removal may well be a more important consideration and more attention must be focused on refining the optimal technique.

Retrospective cohort study of paediatric splenic injuries at a major adult trauma centre in South Africa identifies areas of success and improvement.

This study reviews our experience with paediatric splenic trauma in a major trauma centre in South Africa. We reviewed the management and outcomes of 66 paediatric patients and concluded that selective non-operative management of paediatric splenic trauma can be undertaken successfully in a middle-income country such as South Africa. The grade of splenic injury itself is rarely the sole determinant of operative or non-operative treatment and clinical outcome.

BACKGROUND: Over the last 50 years, the gold standard for paediatric trauma management has grown to be non-operative management. This study reviews a South African experience with paediatric splenic trauma in order to benchmark this against the international standard and to identify discrepancies in access to care and in surgical outcomes. METHODS: This was a retrospective study conducted at a major trauma centre in South Africa. All children less than 18 years of age who were admitted to our trauma centre following trauma between December 2012 and October 2020 were identified and all those who sustained splenic trauma were reviewed. RESULTS: Of the 66 patients reviewed, 48 (72%) were male, and the median age was 12 years (0-18 years). Thirty-three (51%) were of rural origin and 61 (93%) sustained blunt trauma. Only eight (12%) had an isolated splenic injury, while the remaining 58 (88%) had other associated injuries. Forty-five patients (68%) were managed non-operatively whilst the remainder were subjected to laparotomy. Five (7%) required a splenectomy and one required angio-embolisation. Twenty-six patients (39%) required intensive care unit (ICU) admission: 15 (37%) in the non-operative cohort required ICU admission and eight (40%) in the laparotomy group required ICU admission. Twenty-eight (42%) patients required ventilatory support. Median length of stay was 5.5 days. Four (6%) patients died. CONCLUSIONS: Although non-operative management of paediatric splenic trauma can be undertaken successfully by adult trauma surgeons in a middle-income country such as South Africa, there remains room for improvement. To achieve splenic salvage rates comparable to those in dedicated paediatric trauma centres in high-income countries will require systematic quality improvement programmes.

CT scans for pediatric injury in a middle-income country trauma center: Are we repeating past mistakes?

PURPOSE: Sustained efforts in high-income countries have decreased the rate of unnecessary computed tomography (CT) among children, aiming to minimize radiation exposure. There are little data regarding CT use for pediatric trauma in low- and middle-income countries. We aimed to assess the pattern and utility of CT performed during evaluation of trauma patients presenting to a middle-income country (MIC) trauma center. METHODS: We reviewed pediatric (age<18) trauma admissions at a single tertiary referral center in South Africa. Patient demographics, injury details, surgical intervention(s), and mortality were abstracted from the medical record. CT indications, results, and necessity were determined by review. RESULTS: Of 1,630 children admitted to the trauma center, 826 (51%) had CT imaging. Children undergoing imaging were younger (median age 11 [IQR: 6, 16] vs 13 [IQR: 7, 17]) and had higher median ISS [9 [IQR: 4, 13] vs 4 [2, 9]) compared to those without imaging (both p<0.001). Overall, 1,224 scans were performed with normal findings in 609 (50%). A median of 1 scan was performed per patient (range: 1-5). The most common location was CT head (n = 695, 57%). Among patients with positive findings on CT head (n = 443), 31 (7%) underwent either intracranial pressure monitoring or surgery. CT of the cervical spine had positive findings in 12 (7%) with no patients undergoing spine surgery. Of 173 patients with abdominal CT imaging, 83 (48%) had abnormal findings and 18 (10%) required operative exploration. Thirteen (16%) patients with abnormal findings on abdominal CT had exploratory laparotomy. Of 111 children undergoing whole body CT, 8 (7%) underwent thoracic and/or abdominal operations. CONCLUSION: Use of CT during evaluation of pediatric trauma is common in an MIC center. A high rate of normal findings and low rates of intervention following head, cervical spine, and abdominal CT suggest potential overuse of this resource. LEVEL OF EVIDENCE: Level III.

Damage Control Laparotomy: High-Volume Centers Display Similar Mortality Rates Despite Differences in Country Income Level.

BACKGROUND: Comprehensive analysis of trauma care between high-, middle-, and low-income countries (HIC/MIC/LIC) is needed to improve global health. Comparison of HIC and MIC outcomes after damage control laparotomy (DCL) for patients is unknown. We evaluated DCL utilization among patients treated at high-volume trauma centers in the USA and South Africa, an MIC, hypothesizing similar mortality outcomes despite differences in resources and setting. METHODS: Post hoc analysis of prospectively collected trauma databases from participating centers was performed. Injury severity, physiologic, operative data and post-operative outcomes were abstracted. Univariate and multivariable analyses were performed to assess differences between HIC/MIC for the primary outcome of mortality. RESULTS: There were 967 HIC and 602 MIC patients who underwent laparotomy. DCL occurred in 144 MIC patients (25%) and 241 HIC (24%) patients. Most sustained (58%) penetrating trauma with higher rates in the MIC compared to the HIC (71 vs. 32%, p = 0.001). Between groups, no differences were found for admission physiology, coagulopathy, or markers of shock except for increased presence of hypotension among patients in the HIC. Crystalloid infusion volumes were greater among MIC patients, and MIC patients received fewer blood products than those in the HIC. Overall mortality was 30% with similar rates between groups (29 in HIC vs. 33% in MIC, p = 0.4). On regression, base excess and penetrating injury were independent predictors of mortality but not patient residential status. CONCLUSION: Use and survival of DCL for patients with severe abdominal trauma was similar between trauma centers in HIC and MIC settings despite increased penetrating trauma and less transfusion in the MIC center. While the results overall suggest no gap in care for patients requiring DCL in this MIC, it highlights improvements that can be made in damage control resuscitation.
