RESUMO
AIMS: Some pregnant women avoid vehicle driving owing to the risk of contact between their protruding abdomen and steering wheel. This study was performed to determine whether abdominal protrusion in late-term pregnant car users affects the occurrence and severity of abdominal injuries in motor vehicle collisions using a national crash database. METHODS: The National Automotive Sampling System/Crashworthiness Data System was used to analyse maternal background, collision characteristics, outcome and Abbreviated Injury Scale (AIS) scores for the body regions of all persons involved in the collision. RESULTS: Comparison of pregnant and non-pregnant women in the driver's seat showed no significant differences in the rate of AIS scores of ≥2 (2+) for abdominal injuries and female outcomes. Comparison of use of the driver's seat and front passenger's seat by pregnant women showed no significant difference in rate of AIS 2+ injuries or in maternal and fetal outcomes. Comparison of pregnant women with a gestational age of ≤27 and >27 weeks in the driver's seat showed no significant differences in rate of AIS 2+ injuries or in maternal and fetal outcomes. CONCLUSIONS: Based on the data from relatively low-speed frontal collisions, obstetrician/gynaecologists should advise pregnant women that they do not need to change their preferred car seat from the driver's seat to another seat because of fear of contact between their protruding abdomen and the vehicle interior.
RESUMO
BACKGROUND: Abdominal injuries exert a significant impact on global morbidity and mortality. The aggregation of mortality data and its determinants across different regions holds immense importance for designing informed healthcare strategies. Hence, this study assessed the pooled mortality rate and its predictors across sub-Saharan Africa. METHOD: This meta-analysis employed a comprehensive search across multiple electronic databases including PubMed, Africa Index Medicus, Science Direct, and Hinari, complemented by a search of Google Scholar. Subsequently, data were extracted into an Excel format. The compiled dataset was then exported to STATA 17 statistical software for analysis. Utilizing the Dersimonian-Laird method, a random-effect model was employed to estimate the pooled mortality rate and its associated predictors. Heterogeneity was evaluated via the I2 test, while publication bias was assessed using a funnel plot along with Egger's, and Begg's tests. RESULT: This meta-analysis, which includes 33 full-text studies, revealed a pooled mortality rate of 9.67% (95% CI; 7.81, 11.52) in patients with abdominal injuries across sub-Saharan Africa with substantial heterogeneity (I2 = 87.21%). This review also identified significant predictors of mortality. As a result, the presence of shock upon presentation demonstrated 6.19 times (95% CI; 3.70-10.38) higher odds of mortality, followed by ICU admission (AOR: 5.20, 95% CI; 2.38-11.38), blunt abdominal injury (AOR: 8.18, 95% CI; 4.97-13.45), post-operative complications (AOR: 8.17, 95% CI; 4.97-13.44), and the performance of damage control surgery (AOR: 4.62, 95% CI; 1.85-11.52). CONCLUSION: Abdominal injury mortality is notably high in sub-Saharan Africa. Shock at presentation, ICU admission, blunt abdominal injury, postoperative complications, and use of damage control surgery predict mortality. Tailored strategies to address these predictors could significantly reduce deaths in the region.

OBJECTIVE: As one of the most commonly performed cosmetic procedures, liposuction is relatively safe. Bowel injury following liposuction is a rare but devastating complication, which necessitates hospital admission and surgical intervention. The authors highlight a case report describing the presentation, diagnosis, and management of a patient with bowel injury following liposuction. CASE: A 58-year-old woman presented with abdominal pain, erythema, and discharge three days after 360-degree abdominal liposuction with concomitant fat grafting to bilateral buttocks at an outpatient surgery center. Bowel perforation was suspected after CT-scan revealed extraluminal gas in the abdomen and communication that traversed the peritoneum. Exploratory laparotomy was performed which demonstrated at least one site of distinct perforation of the small bowel and an area omentum noted to be inflamed, thickened and with a purulent rind. The patient underwent 20-cm small bowel resection and partial omentectomy temporarily closed with negative pressure wound therapy. After subsequent abdominal wall debridements the patient received ventral hernia repair with bridging mesh and abdominal closure. CONCLUSIONS: While safe, elective cosmetic procedures are not without risk of serious and even fatal complications. Providers must be familiar with the presentation of bowel injury following abdominal liposuction to prevent delays in appropriate surgical and medical care.

OBJECTIVES: Compare the diagnostic performance of the arterial phase plus portovenous phases (AP + PVP) of abdominopelvic CT (CT) with PVP alone in the detection and characterization of traumatic vascular injury and the effects on radiologists' confidence. METHODS: CT of 103 consecutive inpatients (median 36 years, 83 males) with blunt abdominopelvic injuries were retrospectively included if performed within 24 h after trauma and before definitive management. Images were re-reviewed by two blinded radiologists with disagreements resolved by the third radiologist. RESULTS: Sixty vascular injuries (liver 23, spleen 15, kidneys 9, pancreas 2, adrenals 3, mesentery, and pelvis 4 each) were found with 4 injuries (liver 2, spleen, and kidneys 1 each) not detected at initial CT. Nineteen (liver 6, spleen 10, kidneys 2, adrenal 1) were visualized only on AP. The sensitivity and accuracy of AP + PVP were 89.58-91.67% and 94.44-95.15%, compared to 61.67-62.50% and 77.67-80.00% of PVP alone. The agreements on the types of injury with final diagnoses were higher for AP + PVP than for PVP alone (78.69% vs. 44.26%). The mean diagnostic radiologist confidence ((1 = 25%, 2 = 50%, 3 = 75%, 4 > 90%) increased significantly in the detection (from 3.38 to 3.71) and characterization (from 2.46 to 3.67) of vascular injuries with AP + PVP compared to PVP alone. For 19 lesions detected only on AP, 11 (spleen 8, liver 2, adrenal 1) received nonoperative management; others had transarterial embolization or surgery. CONCLUSIONS: The addition of AP improves the detection and characterization of vascular injuries in CT evaluation of blunt abdominopelvic trauma. KEY POINTS: ⢠AP+PVP was more sensitive and precise than PVP alone in the detection of traumatic vascular abdominopelvic injuries. ⢠AP+PVP improved the characterization of traumatic abdominopelvic vascular injuries. ⢠When all abdominopelvic vascular injuries were considered, AP increased radiologists' diagnostic confidence in the detection and characterization of vascular injuries.

OBJECTIVES: To develop a CT-based algorithm and evaluate its performance for the diagnosis of blunt bowel and/or mesenteric injury (BBMI) in patients with blunt abdominal trauma. METHODS: This retrospective study included a training cohort of 79 patients (29 with BBMI and 50 patients with blunt abdominal trauma without BBMI) and a validation cohort of 37 patients (13 patients with BBMI and 24 patients with blunt abdominal trauma without BBMI). CT examinations were blindly analyzed by two independent radiologists. For each CT sign, the kappa value, sensitivity, specificity, and accuracy were calculated. A diagnostic algorithm was built using a recursive partitioning model on the training cohort, and its performances were assessed on the validation cohort. RESULTS: CT signs with kappa value > 0.6 were extraluminal gas, hemoperitoneum, no or moderate bowel wall enhancement, and solid organ injury. CT signs yielding best accuracies in the training cohort were extraluminal gas (98%; 95% CI: 91-100), bowel wall defect (97%; 95% CI: 91-100), irregularity of mesenteric vessels (97%; 95% CI: 90-99), and mesenteric vessel extravasation (97%; 95% CI: 90-99). Using a recursive partitioning model, a decision tree algorithm including extraluminal gas and no/moderate bowel wall enhancement was built, achieving 86% sensitivity (95% CI: 74-99) and 96% specificity (95% CI: 91-100) in the training cohort and 92% sensitivity (95% CI: 78-97) and 88% specificity (95% CI: 74-100) in the validation cohort for the diagnosis of BBMI. CONCLUSIONS: An effective diagnostic algorithm was built to identify BBMI in patients with blunt abdominal trauma using only extraluminal gas and no/moderate bowel wall enhancement on CT examination. KEY POINTS: ⢠A CT diagnostic algorithm that included extraluminal gas and no/moderate bowel wall enhancement was built for the diagnosis of surgical blunt bowel and/or mesenteric injury. ⢠A decision tree combining only two reproducible CT signs has high diagnostic performance for the diagnosis of surgical blunt bowel and/or mesenteric injury.

PURPOSE: To establish the incidence of pancreatic trauma in North Queensland to the region's only tertiary paediatric referral centre, and to determine the patient's outcomes based on their management. METHODS: A single centre, retrospective cohort study of patients < 18 years with pancreatic trauma from 2009 to 2020 was performed. There were no exclusion criteria. RESULTS: Between 2009 and 2020 there were 145 intra-abdominal trauma cases, 37% from motor vehicle accidents (MVA), 18.6% motorbike or quadbike, and 12.4% bicycle or scooter accidents. There were 19 cases of pancreatic trauma (13%), all from blunt trauma and with associated injuries. There were 5 AAST grade I, 3 grade II, 3 grade III, 3 grade IV injuries, and 4 with traumatic pancreatitis. Twelve patients were managed conservatively, 2 were managed operatively for another reason, and 5 were managed operatively for the pancreatic injury. Only 1 patient with a high grade AAST injury was successfully managed non-operatively. Complications included pancreatic pseudocyst (n = 4/19; 3 post-op), pancreatitis (n = 2/19; 1 post op), and post-operative pancreatic fistula (POPF) (n = 1/19). CONCLUSION: Due to North Queensland's geography, diagnosis and management of traumatic pancreatic injury is often delayed. Pancreatic injuries requiring surgery are at high risk for complications, prolonged length of stay, and further interventions.

BACKGROUND: The disadvantages and complications of computed tomography (CT) can be minimized if CT is performed in rib fracture patients with high probability of intra-thoracic and intra-abdominal injuries and CT is omitted in rib fracture patients with low probability of intra-thoracic and intra-abdominal injuries. This study aimed to evaluate the factors that can identify patients with rib fractures with intra-thoracic and intra-abdominal injuries in the emergency department among patients with rib fracture. METHODS: This retrospective observational study included adult patients (age ≥ 18 years) diagnosed with rib fracture on chest radiography prior to chest CT due to blunt chest trauma in the emergency department who underwent chest CT from January 2016 to February 2021. The primary outcomes were intra-thoracic and intra-abdominal injuries that could be identified on a chest CT. Multivariate logistic regression analysis was performed. RESULTS: Among the characteristics of rib fractures, the number of rib fractures was greater (5.0 [3.0-7.0] vs. 2.0 [1.0-3.0], p < 0.001), bilateral rib fractures were frequent (56 [20.1%] vs. 12 [9.8%], p = 0.018), and lateral and posterior rib fracture was more frequent (lateral rib fracture: 160 [57.3%] vs. 25 [20.5%], p < 0.001; posterior rib fracture: 129 [46.2%] vs. 21 [17.2%], p < 0.001), and displacement was more frequent (99 [35.5%] vs. 6 [6.6%], p < 0.001) in the group with intra-thoracic and intra-abdominal injuries than in the group with no injury. The number of rib fractures (adjusted odds ratio [aOR], 1.44; 95% confidence interval [CI], 1.16-1.78; p = 0.001), lateral rib fracture (aOR, 2.80; 95% CI, 1.32-5.95; p = 0.008), and posterior rib fracture (aOR, 3.18; 95% CI, 1.45-6.94; p = 0.004) were independently associated with intra-thoracic and intra-abdominal injuries. The optimal cut-off for the number of rib fractures on the outcome was three. The number of rib fractures ≥ 3 (aOR, 3.01; 95% CI, 1.35-6.71; p = 0.007) was independently associated with intra-thoracic and intra-abdominal injuries. CONCLUSION: In patients with rib fractures due to blunt trauma, those with lateral or posterior rib fractures, those with ≥ 3 rib fractures, and those requiring O2 supplementation require chest CT to identify significant intra-thoracic and intra-abdominal injuries in the emergency department.

PURPOSE: Patients with high-grade renal trauma (HGRT) undergoing nephrectomy may be at higher risk for mortality compared to those treated conservatively. However, no study has controlled for degree of hemorrhage as a measure of shock. We hypothesized that after controlling for blood transfusions and other factors, nephrectomy after HGRT would be associated with increased mortality and acute kidney injury (AKI). MATERIALS AND METHODS: We identified adult patients with HGRT (American Association for the Surgery of Trauma grade III-V) in TQIP (2013-2017). Propensity scoring was used to adjust for the probability of nephrectomy. Conditional logistic regression was used to analyze the association between nephrectomy and mortality and AKI. We adjusted for patient characteristics, injury specifics, and physiological factors including blood transfusions. RESULTS: There were 12,780 patients with HGRT, and 1,014 (7.9%) underwent nephrectomy. Mortality was 10.6% and 4.2% in the nephrectomy and nonnephrectomy groups, respectively (p <0.001). In nephrectomy patients, 8.6% experienced AKI vs 2.4% of nonnephrectomy patients (p <0.001). In the adjusted analysis, there was no association between nephrectomy and mortality (OR=0.367, 95% CI 0.09-1.497, p=0.162). There was also no association between nephrectomy and AKI. Increasing age, nonCaucasian race, increasing Injury Severity Score, decreasing Glasgow Coma Score and blood transfusions were associated with higher mortality. For AKI, independent predictors included increasing age, male sex, and blood transfusions. CONCLUSIONS: After adjusting for volume of blood transfused in the first 24 hours, nephrectomy after HGRT was not associated with increased mortality or AKI. As a clinical principle, trauma nephrectomy should be avoided when possible.

BACKGROUND: The 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. METHODS: All 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. RESULTS: On 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%). CONCLUSION: Our 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.

OBJECTIVE: The severity of handlebar injuries can be overlooked due to subtle signs and wide range of associated internal injuries. Our objective was to describe thoracoabdominal injuries due to bicycle handlebars and their outcomes in children. METHODS: Articles that reported thoracoabdominal injuries were identified from database conception to March 3, 2019 using PubMed, EMBASE, Cochrane Library, CINHAHL Complete, Web of Science and Scopus. A systematic review of studies of thoracoabdominal handlebar injuries in children ≤21 years on human-powered bicycles in English was performed. Information on demographics, clinical features, injuries, interventions and outcomes was noted. RESULTS: A total of 138 articles were identified from 1952 to 2019. There were 1072 children (males, 85.1%) and 1255 thoracoabdominal injuries. Mean age was 9.7 ± 3.3 years old. Common clinical features included abdominal pain and guarding, vomiting, fever and a handlebar imprint. The liver was the most frequently injured organ. Surgery was performed in 338 children with a mean age of 10.0 ± 3.3 years. Twenty-seven children (2.5%) were discharged and returned due to worsening symptoms, of whom 23 (85.2%) required surgery. Thirty-one children (2.9%) transferred to a higher level of care due to injury severity. Two deaths were reported. CONCLUSION: Bicycle handlebars can cause significant thoracoabdominal injuries. Presence of abdominal pain, vomiting, fever or a circular imprint on the chest or abdomen should prompt further workup. Future studies on diagnostic modalities and best practices are needed to lower the chance of missed injuries.

OBJECTIVE: Pediatric focused assessment with sonography for trauma (FAST) is a sequence of ultrasound views rapidly performed by clinicians to diagnose hemorrhage. A technical limitation of FAST is the lack of expertise to consistently acquire all required views. We sought to develop an accurate deep learning view classifier using a large heterogeneous dataset of clinician-performed pediatric FAST. METHODS: We developed and conducted a retrospective cohort analysis of a deep learning view classifier on real-world FAST studies performed on injured children less than 18 years old in two pediatric emergency departments by 30 different clinicians. FAST was randomly distributed to training, validation, and test datasets, 70:20:10; each child was represented in only one dataset. The primary outcome was view classifier accuracy for video clips and still frames. RESULTS: There were 699 FAST studies, representing 4925 video clips and 1,062,612 still frames, performed by 30 different clinicians. The overall classification accuracy was 97.8% (95% confidence interval [CI]: 96.0-99.0) for video clips and 93.4% (95% CI: 93.3-93.6) for still frames. Per view still frames were classified with an accuracy: 96.0% (95% CI: 95.9-96.1) cardiac, 99.8% (95% CI: 99.8-99.8) pleural, 95.2% (95% CI: 95.0-95.3) abdominal upper quadrants, and 95.9% (95% CI: 95.8-96.0) suprapubic. CONCLUSION: A deep learning classifier can accurately predict pediatric FAST views. Accurate view classification is important for quality assurance and feasibility of a multi-stage deep learning FAST model to enhance the evaluation of injured children.

OBJECTIVE: To improve the results of diagnosis and treatment of patients with abdominal injuries through a wider introduction of laparoscopic methods. MATERIAL AND METHODS: We analyzed 3556 patients with concomitant abdominal injuries. All patients had damage to several organs and systems. Laparoscopy was performed in 1962 patients, laparotomy without previous laparoscopy - in 1594 patients. RESULTS: Laparoscopy found no abdominal injuries in 25.7% of patients, other 13.7% of patients required no surgery and follow-up was indicated. In 60.7% of patients, injuries required surgical correction. Among these lesions, 26.6% of injuries were successfully eliminated using laparoscopic approach. In some cases, more than one injury was corrected. Indications for laparotomy were overestimated in 30.2% of patients who underwent open surgery without previous laparoscopy. CONCLUSION: There is a tendency to decrease in the number of open and laparoscopic procedures for concomitant abdominal trauma over time that is associated with widespread introduction of modern diagnostic methods and accumulation of experience. Laparoscopy should be preferred for diagnosis of abdominal injuries in patients with concomitant trauma and no contraindications. This approach diagnoses no injuries or their mild nature in 39.3% of cases. Moreover, laparoscopy effectively eliminates certain lesions in 26.6% of cases.

OBJECTIVES: To evaluate hepatic vascular injury (HVI) on CT in blunt and penetrating trauma and assess its relationship to patient management and outcome. METHOD AND MATERIALS: This retrospective study was IRB approved and HIPAA compliant. Informed consent was waived. Included were patients ≥ 16 years old who sustained blunt or penetrating trauma with liver laceration seen on a CT performed at our institution within 24 h of presentation over the course of 10 years and 6 months (August 2007-February 2018). During this interval, 171 patients met inclusion criteria (123 males, 48 females; mean age 34; age range 17-80 years old). Presence of HVI was evaluated and liver injury was graded in a blinded fashion by two radiologists using the 1994 and 2018 American Association for the Surgery of Trauma (AAST) liver injury scales. Hospital length of stay and treatment (angioembolization or operative) were recorded from the electronic medical record. Multivariate linear regressions were used to determine our variables' impact on the length of stay, and logistic regressions were used for categorical outcomes. RESULTS: Of the included liver trauma patients, 25% had HVI. Patients with HVI had a 3.2-day longer length of hospital stay on average and had a 40.3-fold greater odds of getting angioembolization compared to those without. Patients with high-grade liver injury (AAST grades IV-V, 2018 criteria) had a 3.2-fold greater odds of failing non-operative management and a 14.3-fold greater odds of angioembolization compared to those without. CONCLUSION: HVI in liver trauma is common and is predictive of patient outcome and management. KEY POINTS: ⢠Hepatic vascular injury occurs commonly (25%) with liver trauma. ⢠Hepatic vascular injury is associated with increased length of hospital stay and angioembolization. ⢠High-grade liver injury is associated with failure of non-operative management and with angioembolization.

OBJECTIVE. The objectives of this study were to examine the performance of CT in the diagnosis of ischemic mesenteric laceration after blunt trauma and to assess the predictive value of various CT signs for this injury. MATERIALS AND METHODS. In this retrospective study, consecutive patients with bowel and mesenteric injury diagnosed by CT or surgery from January 2011 through December 2016 were analyzed. Two radiologists evaluated CT images for nine signs of bowel injury. The outcome evaluated was ischemic mesenteric laceration. Univariable analysis followed by logistic regression was performed. RESULTS. The study included 147 patients (96 men and 51 women; median age, 35 years; age range, 23-52 years). Thirty-three patients had surgically confirmed ischemic mesenteric lacerations. CT signs that correlated with ischemic mesenteric laceration were abdominal wall injury, mesenteric contusion, free fluid, segmental bowel hypoenhancement, and bowel hyperenhancement adjacent to a hypoenhancing segment. The regression model developed after inclusion of clinical variables identified two predictors: segmental bowel hypoenhancement (adjusted odds ratio, 22.9 [95% CI, 7.9-66.2; p < .001] for reviewer 1 and 20.7 [95% CI, 7.2-59.0; p < .001] for reviewer 2) and abdominal wall injury (adjusted odds ratio, 5.26 [95% CI, 1.7-15.9; p = .003] for reviewer 1 and 5.3 [95% CI, 1.9-15.0; p = .002] for reviewer 2), which yielded an AUC of 0.87 for predicting injury. For reviewer 1 and reviewer 2, the sensitivities of CT in detecting the injury were 72.3% (95% CI, 54.5-86.7%) and 78.8% (95% CI, 61.0-91.0%), respectively, whereas the specificities were 94.7% (95% CI, 88.9-98.0%), and 92.1% (95% CI, 85.5-96.3%), respectively. CONCLUSION. CT has limited sensitivity but good specificity for detecting ischemic mesenteric laceration, with segmental bowel hypoenhancement considered the most predictive imaging sign.

Trauma represents one of the most common causes of death or permanent disability in the population below 50 years. At present, non-operative treatment is the commonly adopted strategy in hemodynamically stable patients with solid organ injuries, when there are not concomitant bowel and mesenteric injuries requiring a prompt surgical approach, but it may require multiple imaging follow-up examinations, especially in the case of major injuries. No data are available about magnetic resonance imaging utilization in the early follow-up of trauma patients with solid organ injuries, particularly in liver and spleen trauma. We report our preliminary experience in this field.

PURPOSE: There is a common opinion that spinal fractures usually reflect the substantial impact of injuries and therefore may be used as a marker of significant associated injuries, specifically for intra-abdominal injury (IAI). The impact of concomitant spinal cord injury (SCI) with the risk of associated IAI has not been well clarified. The aim of this study was to evaluate the incidence and severity of IAIs in patients suffering from spinal fractures with or without SCI. METHODS: A retrospective cohort study using the Israeli National Trauma Registry was conducted. Patients with thoracic, lumbar and thoracolumbar fractures resulting from blunt mechanisms of injury from January 1, 1997 to December 31, 2018 were examined, comparing the incidence, severity and mortality of IAIs in patients with or without SCI. The collected variables included age, gender, mechanism of injury, incidence and severity of the concomitant IAIs and pelvic fractures, abbreviated injury scale, injury severity score, and mortality. Statistical analysis was performed using GraphPad InStat ® Version 3.10, with Chi-square test for independence and two sided Fisher's exact probability test. RESULTS: Review of the Israeli National Trauma Database revealed a total of 16,878 patients with spinal fractures. Combined thoracic and lumbar fractures were observed in 1272 patients (7.5%), isolated thoracic fractures in 4967 patients (29.4%) and isolated lumbar fractures in 10,639 patients (63.0%). The incidence of concomitant SCI was found in 4.95% (63/1272), 7.65% (380/4967) and 2.50% (266/10639) of these patients, respectively. The overall mortality was 2.5%, proving higher among isolated thoracic fracture patient than among isolated lumbar fracture counterparts (11.3% vs. 4.6%, p < 0.001). Isolated thoracic fractures with SCI were significantly more likely to die than non-SCI counterparts (8.2% vs. 3.1%, p < 0.001). There were no differences in the incidence of IAIs between patients with or without SCI following thoracolumbar fractures overall or in isolated thoracic fractures; although isolated lumbar fractures patients with SCI were more likely to have renal (3.4% vs. 1.6%, p = 0.02) or bowel injuries (2.3% vs. 1.0%, p = 0.04) than the non-SCI counterparts. CONCLUSION: SCI in the setting of thoracolumbar fracture does not appear to be a marker for associated IAI. However, in a subset of isolated lumbar fractures, SCI patient is associated with increased risks for renal and bowel injury.

Background: The choice of diagnostic imaging for high-energy trauma (HET) patients is highly debated. Currently, different diagnostic imaging is used in trauma centres to identify abdominal injuries. However, it remains unclear when physicians have a suspicion for abdominal injuries, and when diagnostic imaging is performed. Over-triage may lead to unnecessary diagnostics in relatively minor injured HET-patients.Purpose: We investigated which clinical factors influence the decision to perform a focused assessment with sonography in trauma (FAST) or abdominal computed tomography (CT) in HET-patients. Additionally, we investigated which clinical factors determined whether HET-patients were admitted to the hospital or discharged from the emergency department.Methods: We performed a retrospective data analysis of all HET-patients in a single level II trauma centre in the Netherlands, between June 2015 and January 2017.Results: 316 HET-patients were included in this study. We found two clinical factors that proved to significantly predict whether a FAST or abdominal CT was performed: abdominal pain and the degree of concomitant injury. Furthermore, we found that the degree of concomitant injury as well as low haemoglobin levels proved to significantly predict whether a patient was admitted to the hospital for observation.Conclusion: This study clarifies on which clinical factors the decision is taken to perform diagnostic imaging to identify abdominal injuries. Future prospective multicentre studies should clarify whether these clinical factors are trustworthy predictors of abdominal injuries, and whether patients can safely be discharged after trauma work-up.

PURPOSE: The blunt abdominal trauma (BAT) is a common emergency and is significantly associated with morbidity and mortality. Our study was conducted to achieve the goal that a new scoring system could be used for the BAT patients. METHODS: The statistical population of this study was 1000 patients with BAT referred to emergency department of Imam Hossein Hospital, Tehran, Iran. Sampling was carried out in a convenience non-random manner and continued to reach the required sample size. All the patients with BAT due to road traffic accidents, falls, and other direct blunt traumas such as punctures and kickbacks were included in the study. Exclusion criteria were after 3 months of pregnancy, under the age of 18, warfarin taking, no reliable medical history providing and penetrating trauma. The study questionnaire was based on BAT scoring system. The data were analyzed by SPSS V20 software. The receiver operating characteristic curve was used to analyze the effectiveness of the new scoring system in predicting the BAT patients' outcome. RESULTS: The mean age of the patients (n = 1000) was (35.79 ± 13.09) years. The mean score of patients was (6.29 ± 5.80). Based on this scoring system, the patients were divided into three categories. The first group was patients at low risk with score of less than 8, the second group was patients at moderate risk with score of 8-12 and the third group was patients at high risk with score of 12-24. The score of 661 (66.1%) patients were low, 109 (10.9%) were moderate and 230 (23%) had a high score. The association between hip fracture and abdominal tenderness with abdominal injury was significant (p < 0.001). Cronbach's alpha was 0.76 showing the reliability of this questionnaire to predict the future of patients. CONCLUSIONS: The study tool has a sensitivity to predict the BAT patients' outcome, and has a proper specificity that can be used to reduce the use of harmful modalities such as computed tomography scan.

INTRODUCTION: Point-of-care ultrasound (POCUS) has the potential to improve access to diagnostic imaging for rural communities. This article evaluates the sensitivity and specificity, impact on patient care, quality and safety of two common POCUS examinations - focused assessment with sonography in trauma (FAST) and aortic aneurysm (AAA) - in the rural context. METHODS: This study is a subgroup analysis of a larger study into POCUS in rural New Zealand. Twenty-eight physicians in six New Zealand rural hospitals, with limited access to formal diagnostic imaging, completed a questionnaire before and after POCUS scans to assess the extent to which it altered diagnostic certainty and patient disposition (discharge v admission to rural hospital v transfer to urban hospital). The investigators and a specialist panel reviewed images for technical quality and accuracy of interpretation, and patient clinical records, to determine accuracy of the POCUS findings and their impact on patient care. RESULTS: For FAST and AAA scans respectively, sensitivities were 75% and 100%, and specificities 100% and 93%; rural doctors correctly interpreted their POCUS images for 97% and 91% of scans. The proportions of scans that had either a 'significant' or 'major' impact on patient care were 17% and 31%. POCUS resulted in the disposition being de-escalated for 15% and 10% of patients and escalated for 5% and 3% of patients. CONCLUSIONS: In the rural context, POCUS AAA is a reliable 'rule out' test for ruptured abdominal aortic aneurysm and FAST scan has a role as a 'rule in' test for solid organ injury. These findings are consistent with larger studies in the emergency medicine literature.
