Abstract
PURPOSE Duodenal/pancreatic injuries occur in less than 10% of intra-abdominal injuries in pediatric blunt trauma. Isolated duodenal/pancreatic injuries occur in two-thirds of cases, while combined injuries occur in the remaining. This study aimed to investigate pediatric patients with pancreatic and duodenal trauma. METHODS Data from 31 patients admitted to Atatürk University, Medical Faculty, Department of Pediatric Surgery for pancreatic/duodenal trauma between 2010 and 2019 were retrospectively analyzed. Age/gender, province of origin, duration before hospital admission, trauma type, injured organs, injury severity, diagnostic and therapeutic modalities, complications, hospitalization duration, blood transfusion requirement, and mortality rate were recorded. RESULTS Twenty-four patients were male, and 7 were female. The mean age was 9 years. The leading cause was bicycle accidents, with 12 cases, followed by traffic accidents/bumps, with 7 cases each. Comorbid organ injuries accompanied 18 cases. Duodenal trauma was most commonly accompanied by liver injuries (4/8), whereas pancreatic injury by pulmonary injuries (7/23). Serum amylase at initial hospital presentation was elevated in 83.9% of the patients. Thirty patients underwent abdominal CT, and FAST was performed in 20. While 54.8% of the patients were conservatively managed, 45.2% underwent surgery. CONCLUSION Because of the anatomical proximity of the pancreas and the duodenum, both organs should be considered being co-affected by a localized trauma. Radiologic confirmation of perforation in duodenal trauma and an intra-abdominal pancreatic pseudocyst in pancreatic trauma are the most critical surgical indications of pancreaticoduodenal trauma. Conservative management's success is increased in the absence of duodenal perforation and cases of non-symptomatic pancreatic pseudocyst.

Abstract
This study evaluated automated machine learning (AutoML) in classifying the presence or absence of hemoperitoneum in ultrasonography (USG) images of Morrison's pouch. In this multicenter, retrospective study, 864 trauma patients from trauma and emergency medical centers in South Korea were included. In all, 2200 USG images (1100 hemoperitoneum and 1100 normal) were collected. Of these, 1800 images were used for training and 200 were used for the internal validation of AutoML. External validation was performed using 100 hemoperitoneum images and 100 normal images collected separately from a trauma center that were not included in the training and internal validation sets. Google's open-source AutoML was used to train the algorithm in classifying hemoperitoneum in USG images, followed by internal and external validation. In the internal validation, the sensitivity, specificity, and area under the receiver operating characteristic (AUROC) curve were 95%, 99%, and 0.97, respectively. In the external validation, the sensitivity, specificity, and AUROC were 94%, 99%, and 0.97, respectively. The performances of AutoML in the internal and external validation were not statistically different (p = 0.78). A publicly available, general-purpose AutoML can accurately classify the presence or absence of hemoperitoneum in USG images of the Morrison's pouch of real-world trauma patients.

Abstract
OBJECTIVES The predictive accuracy and clinical role of the focused assessment with sonography for trauma (FAST) exam in pediatric blunt abdominal trauma are uncertain. This study investigates the performance of the emergency department (ED) FAST exam to predict early surgical intervention and subsequent free fluid (FF) in pediatric trauma patients. METHODS Pediatric level 1 trauma patients ages 0 to 15 years with blunt torso trauma at a single trauma center were retrospectively reviewed. After stratification by initial hemodynamic (HD) instability, the association of a positive FAST with (1) early surgical intervention, defined as operative management (laparotomy or open pericardial window) or angiography within 4 hours of ED arrival and (2) presence of FF during early surgical intervention was determined. RESULTS Among 508 salvageable pediatric trauma patients with an interpreted FAST exam, 35 (6.9%) had HD instability and 98 (19.3%) were FAST positive. A total of 42 of 508 (8.3%) patients required early surgical intervention, and the sensitivity and specificity of FAST predicting early surgical intervention were 59.5% and 84.3%, respectively. The specificity and positive predictive value of FF during early surgical intervention in FAST-positive HD unstable patients increased from 50% and 90.9% at 4 hours after ED arrival to 100% and 100% at 2 hours after ED arrival, respectively. CONCLUSIONS In this large series of injured children, a positive FAST exam improves the ability to predict the need for early surgical intervention, and accuracy is greater for FF in HD unstable patients 2 hours after arrival to the ED.

Abstract
Objective: Focused assessment with sonography for trauma (FAST) is a widely used imaging technique for the diagnosis of blunt abdominal trauma and has its limitations and advantages. A meta-analysis was completed to evaluate the reliability of FAST, in the diagnosis of blunt torso trauma. Materials and Methods: A search was completed with Google Scholar, PubMed, National Center for Biotechnology Information (NCBI), MEDLINE, and Medscape databases, from 1993 up to 2020. Eligible studies were included for information about FAST examination of abdominal trauma. The animal research was excluded from this review process. The eligible studies were first categorized and then data analysis was performed, according to specific pathologic conditions. This literature review retrieved studies’ sample size, application, sensitivity, and a specificity of diagnosis using FAST for abdominal trauma. Results: In total, 100 articles were identified through the database search. Besides, five articles were identified through other sources. Then, screening was performed, and as such, 46 published studies were included that had a qualitative synthesis. Conclusion: FAST has a high sensitivity and specificity in the diagnosis of blunt abdominal trauma. However, a large range of sensitivity and specificity of FAST in the evaluation of torso trauma reveal that sonography is operator, technique, and equipment dependent.

Abstract
BACKGROUND Gallbladder perforation is a very rare finding in children. Clinical and radiografic presentations are often vague. Hence it is a challenging diagnosis, often missed during initial evaluation with potentially fatal consequences. The aim of this case report and review was to identify factors that might help to diagnose and manage future cases. METHODS We present a case of gallbladder perforation in an 8-year-old child after blunt abdominal trauma caused by a handlebar in which imaging modalities such as ultrasound and magnetic resonance imaging (MRI) helped us to determine proper management. We identified and evaluated comparable cases for isolated traumatic gallbladder injury. A review of the recent literature was performed by online search in Pubmed and Google Scholar using "gallbladder injury in children", "gallbladder perforation children", "blunt abdominal trauma children" as keywords. We focused on articles exclusively in the pediatric section. The literature from the period 2000-2020 was taken into account to review the state of the art in diagnosis and management. RESULTS AND CONCLUSION Recent literature for gallbladder injury in pediatrics is sparse compared to the adult counterpart. Only eight published cases of isolated gallbladder injury in children were identified. Since the onset of symptoms may not develop acutely and often develops in an indistinct manner, radiografic examinations play an important role in the diagnostic progress. The authors advise caution in cases of blunt abdominal trauma especially involving handlebars, intraperitoneal free fluid, and severe abdominal pain. We advocate high suspicion of gallbladder perforation if the gallbladder wall displays discontinuation or cannot be definitively differentiated in sonografic examination. Echogenic fluid within the gallbladder should always lead to suspicion of intraluminal bleeding. Repeated clinical and imaging examinations are mandatory since the onset of signs and symptoms may be delayed. KEY POINTS · Awareness of gallbladder perforation in blunt abdominal trauma of the upper abdomen.. · Particularly high index of suspicion in cases involving handlebar injuries.. · Repeated clinical and imaging examinations are highly recommended..

Abstract
PURPOSE In children with blunt abdominal trauma (BAT), focused assessment of sonography in trauma (FAST) has been reported with low sensitivity, on the whole, in the detection of intra-abdominal injuries (IAI). The aim of the present study was to assess test characteristics of FAST using different strategies including repeated FAST (reFAST), and physical exam findings. METHODS This retrospective study evaluated BAT pediatric patients with stable hemodynamics who underwent computed tomography (CT). Demographic data, initial physical examination, and results of FAST, reFAST (if done), and CT imaging were recorded. Different strategies of FAST were cross-tabulated with CT as the gold standard and test characteristics including sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were interpreted. RESULTS 129 patients with a mean age of 8.6 ± 4.7 were studied and 74% were male. Comparing CT-positive and -negative groups, from the demographic and clinical findings, only positive physical exam (tenderness or ecchymosis) was significantly higher in the CT-positive group (59% vs. 17%; p < 0.01). In a multivariate analysis, positive FAST modality and clinical exam remained independent predictors for a positive CT result (likelihood ratios of 34.6 and 6.4, respectively). Out of the different diagnostic strategies for the prediction of IAI, the best overall performance resulted from the FAST-reFAST-tenderness protocol with sensitivity, specificity, PPV, NPV, and accuracy of 87%, 77%, 70%, 91%, and 81%. CONCLUSION For children with blunt abdominal trauma, physical examination plus FAST and reFAST as needed, seems to have reasonable sensitivity, specificity, and accuracy in detecting intra-abdominal injuries and may reduce the need for CT scans.

Abstract
OBJECTIVES Abdominal computed tomography (ACT) use in the initial evaluation of pediatric abdominal trauma is liberal in most instances. The aim of this study was to identify the predictors for a positive yield ACT scan in this population. METHODS A prospective, cohort, single-center observational study was conducted at Children's Hospital at Westmead, New South Wales, from January 2008 to June 2015 on 240 pediatric abdominal trauma patients who had abdominal computed tomography. Clinical, laboratory, imaging, and interventional variables were explored with univariate and multivariate analyses among children who sustained abdominal trauma. RESULTS Of 240 patients, positive ACT scans were found in 161 patients (67%), 112 patients (47%) had intra-abdominal injury, and 20 patients (8%) required invasive therapeutic interventions. Mortality rate was 1.7% (4 patients) due to nonabdominal causes. Multivariate analyses revealed that increasing age (odds ratio [OR], 1.12; 95% confidence interval [CI], 1.02-1.24; P = 0.024), high injury severity score (OR, 1.14; 95% CI, 1.07-1.21; P < 0.001), abnormal abdominal examination (OR, 5.95; 95% CI, 2.08-17.01; P = 0.001), elevated alanine aminotransferase greater than 125 IU/L (OR, 46.28; 95% CI, 2.81-762.49; P = 0.007), abnormal pelvic radiograph (OR, 14.03; 95% CI, 2.39-82.28; P = 0.003), presence of gross hematuria (OR, 4.14; 95% CI, 1.04-18.23; P = 0.044), low initial hematocrit level (less than 30%) (OR, 8.51; 95% CI, 1.14-63.70; P = 0.037), and positive focused assessment with sonography for trauma (OR, 2.61; 95% CI, 1.01-7.28; P = 0.048) remained significantly associated with abnormal ACT scan. In contrast, those who required scanning of other body region(s) were less likely to have abnormal ACT scan (OR, 0.34; 95% CI, 0.14-0.86; P =0.022). CONCLUSIONS Integrating the abdominal examination findings, relevant laboratory values, and focused assessment with sonography for trauma results with the physicians' suspicion may aid in stratifying patients for ACT scan. Further efforts should be made to decrease number of normal ACT scans; yet not to increase the number of delayed or missed injures with its inherent morbidity and mortality.

Abstract
OBJECTIVES Computed tomography (CT), the reference standard for diagnosis of intraabdominal injury (IAI), carries risk including ionizing radiation. CT-sparing clinical decision rules for children have relied heavily on physical examination, but they did not include focused assessment with sonography for trauma (FAST), which has emerged into widespread use during the past decade. We sought to determine the independent associations of physical examination, laboratory studies, and FAST with identification of IAI in children and to compare the test characteristics of these diagnostic variables. We hypothesized that FAST may add incremental utility to a physical examination alone to more accurately identify children who could forgo CT scan. METHODS We reviewed a large trauma database of all children with blunt torso trauma presenting to a freestanding pediatric emergency department during a 20-month period. We used logistic regression to evaluate the association of FAST, physical examination, and selected laboratory data with IAI in children, and we compared the test characteristics of these variables. RESULTS Among 354 children, 50 (14%) had IAI. Positive FAST (odds ratio [OR] = 14.8, 95% confidence interval [CI] = 7.5 to 30.8) and positive physical examination (OR = 15.2, 95% CI = 7.7 to 31.7) were identified as independent predictors for IAI. Physical examination and FAST each had sensitivities of 74% (95% CI = 60% to 85%). Combining FAST and physical examination as FAST-enhanced physical examination (exFAST) improved sensitivity and negative predictive value (NPV) over either test alone (sensitivity = 88%, 95% CI = 76% to 96%) and NPV of 97.3% (95% CI = 94.5% to 98.7%). CONCLUSIONS In children, FAST and physical examinations each predicted the identification of IAI. However, the combination of the two (exFAST) had greater sensitivity and NPV than either physical examination or FAST alone. This supports the use of exFAST in refining clinical predication rules in children with blunt torso trauma.

Abstract
Purpose: To characterize injury patterns and institutional trends associated with the utilization of laparoscopy in the management of pediatric abdominal trauma. Methods: The National Trauma Data Bank (2010-2014) was queried for encounters involving patients ≤14 years who underwent an open or laparoscopic abdominal operation within 48 hours of emergency department arrival. Patient, injury, and hospital characteristics associated with each approach were identified. Multivariate logistic regression was used to evaluate the influence of patient and hospital characteristics on operative approach. Results: Laparoscopy comprised 7.8% (n = 355) of all abdominal trauma operations. Patients undergoing laparoscopy had lower injury severity scores and higher Glasgow Coma Scale scores on arrival compared with laparotomy subjects (P < .001). Laparoscopic patients also had a shorter length of hospital stay (5.0 versus 8.6 days, P < .001), but longer time to the operating room (9.2 versus 6.3 hours, P < .001) compared with their open counterparts. The proportion of cases managed laparoscopically increased from 6.2% in 2010 to 10.1% in 2014 (P = .013), with increase in utilization primarily driven by university hospitals (P = .026) and level I pediatric trauma centers (P = .043). Conversion to laparotomy was uncommon (18.6%), and mortality in the laparoscopic cohort was low (0.4%). Conclusions: Use of laparoscopy has increased in the pediatric abdominal trauma population, typically in a less injured cohort of patients. As familiarity with and availability of minimally invasive techniques increase, this trend will likely continue.

Abstract
Background The ability of focused assessment with sonography for trauma (FAST) to detect clinically significant hemorrhage in hypotensive injured patients remains unclear. We sought to describe the sensitivity and specificity of FAST using findings at laparotomy as the confirmatory test. Methods Patients from the Prospective Observational Multicenter Major Trauma Transfusion (PROMMTT) study that had a systolic blood pressure < 90mm Hg and underwent FAST were analysed. Results were compared with findings at laparotomy. A therapeutic laparotomy (T-LAP) was defined as an abdominal operation within 6 hours in which a definitive procedure was performed. The sensitivity and specificity of FAST were calculated. Results The cohort included 317 patients that underwent FAST (108 positive, 209 negative). T-LAP was performed in 69% (n=75) of FAST(+) patients and 22% (n=48) of FAST(−) patients. FAST had a sensitivity of 62% and specificity of 83%. Conclusions In our multicenter cohort, 22% of FAST(−) patients underwent T-LAP within 6 hours of admission. In hypotensive patients with a negative FAST, clinicians should still maintain a high index of suspicion for significant abdominal hemorrhage. Level of evidence Level IV.

Abstract
BACKGROUND Point-of-care sonography (POCS) has emerged as the screening modality of choice for suspected body trauma in many emergency departments worldwide. Its best known application is FAST (focused abdominal sonography for trauma). The technology is almost ubiquitously available, can be performed during resuscitation, and does not expose patients or staff to radiation. While many authors have stressed the high specificity of POCS, its sensitivity varied markedly across studies. This review aimed to compile the current best evidence about the diagnostic accuracy of POCS imaging protocols in the setting of blunt thoracoabdominal trauma. OBJECTIVES To determine the diagnostic accuracy of POCS for detecting and excluding free fluid, organ injuries, vascular lesions, and other injuries (e.g. pneumothorax) compared to a diagnostic reference standard (i.e. computed tomography (CT), magnetic resonance imaging (MRI), thoracoscopy or thoracotomy, laparoscopy or laparotomy, autopsy, or any combination of these) in patients with blunt trauma. SEARCH METHODS We searched Ovid MEDLINE (1946 to July 2017) and Ovid Embase (1974 to July 2017), as well as PubMed (1947 to July 2017), employing a prospectively defined literature and data retrieval strategy. We also screened the Cochrane Library, Google Scholar, and BIOSIS for potentially relevant citations, and scanned the reference lists of full-text papers for articles missed by the electronic search. We performed a top-up search on 6 December 2018, and identified eight new studies which may be incorporated into the first update of this review. SELECTION CRITERIA We assessed studies for eligibility using predefined inclusion and exclusion criteria. We included either prospective or retrospective diagnostic cohort studies that enrolled patients of any age and gender who sustained any type of blunt injury in a civilian scenario. Eligible studies had to provide sufficient information to construct a 2 x 2 table of diagnostic accuracy to allow for calculating sensitivity, specificity, and other indices of diagnostic test accuracy. DATA COLLECTION AND ANALYSIS Two review authors independently screened titles, abstracts, and full texts of reports using a prespecified data extraction form. Methodological quality of individual studies was rated by the QUADAS-2 instrument (the revised and updated version of the original Quality Assessment of Diagnostic Accuracy Studies list of items). We calculated sensitivity and specificity with 95% confidence intervals (CI), tabulated the pairs of sensitivity and specificity with CI, and depicted these estimates by coupled forest plots using Review Manager 5 (RevMan 5). For pooling summary estimates of sensitivity and specificity, and investigating heterogeneity across studies, we fitted a bivariate model using Stata 14.0. MAIN RESULTS We included 34 studies with 8635 participants in this review. Summary estimates of sensitivity and specificity were 0.74 (95% CI 0.65 to 0.81) and 0.96 (95% CI 0.94 to 0.98). Pooled positive and negative likelihood ratios were estimated at 18.5 (95% CI 10.8 to 40.5) and 0.27 (95% CI 0.19 to 0.37), respectively. There was substantial heterogeneity across studies, and the reported accuracy of POCS strongly depended on the population and affected body area. In children, pooled sensitivity of POCS was 0.63 (95% CI 0.46 to 0.77), as compared to 0.78 (95% CI 0.69 to 0.84) in an adult or mixed population. Associated specificity in children was 0.91 (95% CI 0.81 to 0.96) and in an adult or mixed population 0.97 (95% CI 0.96 to 0.99). For abdominal trauma, POCS had a sensitivity of 0.68 (95% CI 0.59 to 0.75) and a specificity of 0.95 (95% CI 0.92 to 0.97). For chest injuries, sensitivity and specificity were calculated at 0.96 (95% CI 0.88 to 0.99) and 0.99 (95% CI 0.97 to 1.00). If we consider the results of all 34 included studies in a virtual population of 1000 patients, based on the observed median prevalence (pretest probability) of thoracoabdominal trauma of 28%, POCS would miss 73 patients with injuries and falsely suggest the presence of injuries in another 29 patients. Furthermore, in a virtual population of 1000 children, based on the observed median prevalence (pretest probability) of thoracoabdominal trauma of 31%, POCS would miss 118 children with injuries and falsely suggest the presence of injuries in another 62 children. AUTHORS' CONCLUSIONS In patients with suspected blunt thoracoabdominal trauma, positive POCS findings are helpful for guiding treatment decisions. However, with regard to abdominal trauma, a negative POCS exam does not rule out injuries and must be verified by a reference test such as CT. This is of particular importance in paediatric trauma, where the sensitivity of POCS is poor. Based on a small number of studies in a mixed population, POCS may have a higher sensitivity in chest injuries. This warrants larger, confirmatory trials to affirm the accuracy of POCS for diagnosing thoracic trauma.

Abstract
IMPORTANCE Point-of-care ultrasonography (POCUS) allows to obtain real-time images to correlate with the patient's presenting signs and symptoms. It can be used by various specialties and may be broadly divided into diagnostic and procedural applications. OBJECTIVE We aimed at reviewing current knowledge on the use of POCUS in Pediatric Emergency Departments (PEDs). FINDINGS US diagnostic capacity in paediatric patients with suspected pneumonia has been studied and debated whereas literature regarding the usefulness of point-of-care echocardiography in the pediatric setting is still limited. Similarly, Focused Assessment with Sonography for Trauma (FAST) has become a standard procedure in adult emergency medicine but it is still not well codified in the pediatric practice. Concerning procedural applications of POCUS we identified 4 main groups: peripheral vascular access, bladder catheterizations, identification and drainage of abnormal fluid collections and foreign body identification. CONCLUSIONS AND RELEVANCE Bedside emergency ultrasound is routinely used by adult emergency physicians and in the last 10 years its application is recognized and applied in PED. Pediatric emergency physicians are encouraged to familiarize with POCUS as it is a safe technology and can be extremely helpful in performing diagnosis, managing critical situations and guiding procedures, which results in globally improving pediatric patients care.

Abstract
INTRODUCTION Focused assessment with sonography for trauma (FAST) has been shown to be useful to detect intraperitoneal free fluid in patients with blunt abdominal trauma (BAT). OBJECTIVE We compared the diagnostic accuracy of FAST performed by emergency medicine residents (EMRs) and radiology residents (RRs) in pediatric patients with BAT. METHOD In this prospective study, pediatric patients with BAT and high energy trauma who were referred to the emergency department (ED) at Al-Zahra and Kashani hospitals in Isfahan, Iran, were evaluated using FAST, first by EMRs and subsequently by RRs. The reports provided by the two resident groups were compared with the final outcome based on the results of the abdominal computed tomography (CT), operative exploration, and clinical observation. RESULTS A total of 101 patients with a median age of 6.75 ± 3.2 years were enrolled in the study between January 2013 and May 2014. These patients were evaluated using FAST, first by EMRs and subsequently by RRs. A good diagnostic agreement was noted between the results of the FAST scans performed by EMRs and RRs (κ = 0.865, P < 0.001). The sensitivity, specificity, positive and negative predictive values, and accuracy in evaluating the intraperitoneal free fluid were 72.2%, 85.5%, 52%, 93.3%, and 83.2%, respectively, when FAST was performed by EMRs and 72.2%, 86.7%, 54.2%, 93.5%, and 84.2%, respectively, when FAST was performed by RRs. No significant differences were seen between the EMR- and RR-performed FAST. CONCLUSION In this study, FAST performed by EMRs had acceptable diagnostic value, similar to that performed by RRs, in patients with BAT.

Abstract
Contrast-enhanced ultrasound (CEUS) is a radiation-free, safe, and in specific clinical settings, highly sensitive imaging modality. Over the recent decades, there is cumulating experience and a large volume of published safety and efficacy data on pediatric CEUS applications. Many of these applications have been directly translated from adults, while others are unique to the pediatric population. The most frequently reported intravenous abdominal applications of CEUS in children are the characterization of focal liver lesions, monitoring of solid abdominal tumor response to treatment, and the evaluation of intra-abdominal parenchymal injuries in selected cases of blunt abdominal trauma. The intravesical CEUS application, namely contrast-enhanced voiding urosonography (ceVUS), is a well-established, pediatric-specific imaging technique entailing the intravesical administration of ultrasound contrast agents for detection and grading of vesicoureteral reflux. In Europe, all pediatric CEUS applications remain off-label. In 2016, the United States Food and Drug Administration (FDA) approved the most commonly used worldwide second-generation ultrasound contrast SonoVue®/Lumason® for pediatric liver and intravesical applications, giving new impetus to pediatric CEUS worldwide.

Abstract
In pediatrics ultrasound has long been viewed more favorably than imaging that exposes patients to radiation and iodinated contrast or requires sedation. It is child-friendly and diagnostic capabilities have been improved with the advent of contrast-enhanced ultrasound (CEUS). The application of CEUS is indeed promising. However, no ultrasound contrast agent manufactured today is registered for pediatric use in Europe. The contrast agent SonoVue® has recently been approved by the FDA under the name of Lumason® to be used in hepatic investigations in adults and children. This article reviews the literature with respect to 2 specific applications of CEUS in children: 1) identification of parenchymal injuries following blunt abdominal trauma, and 2) classification of focal liver lesions. Applications were chosen through the CEUS guidelines published by the European Federation of Societies for Ultrasound in Medicine and Biology and World Federation for Ultrasound in Medicine and Biology. Literature was obtained by searching Medline and Pubmed Central (using Pubmed), Scopus database and Embase. CEUS proved to be an effective investigation in the hemodynamically stable child for identifying parenchymal injuries and for the characterization of focal liver lesions. CEUS showed comparable performance to CT and MRI with a specificity of 98% for identifying benign lesions and a negative predictive value of 100%. For the applications reviewed here, CEUS holds promising perspectives and can help reduce radiation exposure and use of iodinated contrast agents in pediatrics, thereby potentially reducing complications in routine imaging.

Abstract
BACKGROUND/PURPOSE This study aims to investigate differences in imaging, procedure utilization, and clinical outcomes of severely injured adolescents treated at adult versus pediatric trauma centers. METHODS The National Trauma Data Bank was queried retrospectively for adolescents, 15-19years old, with a length of stay (LOS) >1day and Injury Severity Score (ISS) >25 treated at adult (ATC) or pediatric (PTC) Level 1 trauma centers from 2007 to 2011. Patient demographics and utilization of imaging and procedures were analyzed. Univariate and multivariate regression analysis was used to compare outcomes. RESULTS Of 12,861 adolescents, 51% were treated at ATC. Older age and more nonwhites were seen at ATC (p<0.01). Imaging and invasive procedures were more common at ATC (p<0.01). Shorter LOS (p=0.03) and higher home discharge rates (p<0.01) were seen at PTC. ISS and mortality did not differ. Age, race, ATC care (all p<0.01), and admission systolic blood pressure (SBP) (p=0.03) were predictors of CT utilization. ISS, SBP, and race (p<0.01) were risk factors for overall mortality; SBP (p=0.03) and ISS (p<0.01) predicted death from penetrating injury. CONCLUSIONS Severely injured adolescents experience improved outcomes and decreased imaging and invasive procedures without additional mortality risk when treated at PTC. PTC is an appropriate destination for severely injured adolescents.

Abstract
Background Trauma is currently the fourth leading cause of death in developed countries. One of the main objectives in abdominal trauma patients is to develop a rapid and accurate diagnosis. There is a tendency to use emergency abdominal ultrasound with abdominal trauma, therefore, it is recommended in some centers as a diagnostic tool and as a primary choice in abdominal trauma. Objectives The aim of this study was to determine the diagnostic accuracy of sonography for trauma by emergency medicine residents and radiology residents Patients and Methods This was a descriptive and analytical study performed on patients with abdominal blunt trauma who referred to the emergency ward. The diagnostic accuracy of sonography for trauma by emergency medicine residents and radiology residents was evaluated. Results Of the 380 patients, 296 were males and 84 were females. The mean ages of male and female patients were 34.52 ± 16.38 years and 41.19 ± 21.38 years, respectively (P = 0.009). The sonographies performed by emergency residents were positive in 46 patients, with 22 of these confirmed by CT scans. The sensitivity and specificity of the sonography by emergency residents, as confirmed by CT scans, were 78.5% and 93.2%, respectively. The sonographies performed by radiology residents were positive in 38 patients, with 24 being confirmed by CT scans. Conclusions The sensitivity and specificity of the sonography by radiology residents, as confirmed by CT scans, were 85.7% and 96%, respectively. Sonographies performed by emergency residents were positive in 46 patients with 34 of these being confirmed by sonographies by radiology residents. The sensitivity and specificity of the sonographies by emergency residents, as confirmed by sonographies by radiology residents, were 89.5% and 96.5%, respectively

Abstract
Baseline ultrasound is essential in the early assessment of patients with a huge haemoperitoneum undergoing an immediate abdominal surgery; nevertheless, even with a highly experienced operator, it is not sufficient to exclude parenchymal injuries. More recently, a new ultrasound technique using second generation contrast agents, named contrast-enhanced ultrasound (CEUS) has been developed. This technique allows all the vascular phase to be performed in real time, increasing ultrasound capability to detect parenchymal injuries, enhancing some qualitative findings, such as lesion extension, margins and its relationship with capsule and vessels. CEUS has been demonstrated to be almost as sensitive as contrast-enhanced CT in the detection of traumatic injuries in patients with low-energy isolated abdominal trauma, with levels of sensitivity and specificity up to 95%. Several studies demonstrated its ability to detect lesions occurring in the liver, spleen, pancreas and kidneys and also to recognize active bleeding as hyperechoic bands appearing as round or oval spots of variable size. Its role seems to be really relevant in paediatric patients, thus avoiding a routine exposure to ionizing radiation. Nevertheless, CEUS is strongly operator dependent, and it has some limitations, such as the cost of contrast media, lack of panoramicity, the difficulty to explore some deep regions and the poor ability to detect injuries to the urinary tract. On the other hand, it is timesaving, and it has several advantages, such as its portability, the safety of contrast agent, the lack to ionizing radiation exposure and therefore its repeatability, which allows follow-up of those traumas managed conservatively, especially in cases of fertile females and paediatric patients.

Abstract
Introduction In pediatric care, the role of focused abdominal sonography in trauma (FAST) remains ill defined. The objective of this study was to assess the sensitivity and specificity of FAST for detecting free peritoneal fluid in children. Methods The trauma registry of a single level I pediatric trauma center was queried for the results of FAST examination of consecutive pediatric (<18 years) blunt trauma patients over a period of 36 months, from January 2010 to December 2012. Demographics, type of injuries, FAST results, computerized tomography (CT) results, and operative findings were reviewed. Results During the study period, 543 injured pediatric patients (mean age 8.2 ± 5 years) underwent FAST examinations. In 95 (17.5 %) FAST was positive for free peritoneal fluid. CT examination was performed in 219 (40.3 %) children. Positive FAST examination was confirmed by CT scan in 61/73 (83.6 %). CT detected intra-peritoneal fluid in 62/448 (13.8 %) of the patients with negative FAST results. These findings correspond to a sensitivity of 50 %, specificity of 88 %, positive predictive value (PPV) of 84 %, and a negative predictive value (NPV) of 58 %. In patients who had negative FAST results and no CT examination (302), no missed abdominal injury was detected on clinical ground. FAST examination in the young age group (<2 years) yielded lower sensitivity and specificity (36 and 78 % respectively) with a PPV of only 50 %. Conclusions This study shows that although a positive FAST evaluation does not necessarily correlate with an IAI, a negative one strongly suggests the absence of an IAI, with a high NPV. These findings are emphasized in the analysis of the subgroup of children less than 2 years of age. FAST examination tempered with sound clinical judgment seems to be an effective tool to discriminate injured children in need of further imaging evaluation.

Accuracy of contrast-enhanced ultrasound (CEUS) in the identification and characterization of traumatic solid organ lesions in children: a retrospective comparison with baseline US and CE-MDCT. Radiol Med 2015; 120:989-1001. [PMID: 25822953 DOI: 10.1007/s11547-015-0535-z] [Citation(s) in RCA: 58] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2015] [Accepted: 03/20/2015] [Indexed: 02/07/2023]
Abstract
INTRODUCTION Localized low-energy abdominal trauma is very frequent in the pediatric population. The findings of several studies have shown that ultrasonography (US) can represent a useful and cost-effective tool in the evaluation of blunt abdominal trauma both in adults and children. However, many parenchymal injuries are not correctly visualized at baseline US examination. The introduction of specific US contrast agents contrast-enhanced ultrasound (CEUS) has enabled a better identification of traumatic organ injuries. The correct use of CEUS could therefore identify and select the children who need further diagnostic investigation computed tomography (CT), avoiding unnecessary radiation and iodinated contrast medium exposure. The purpose of our study was to assess the sensibility and feasibility of CEUS in the assessment of low-energy abdominal trauma compared to baseline US in pediatric patients, using contrast-enhanced MDCT as the reference standard. MATERIALS AND METHODS We retrospectively reviewed 73 children (51 M and 22 F; mean age 8.7 ± 2.8 years) who presented in our Emergency Department between October 2012 and October 2013, with history of minor abdominal trauma according to the Abbreviated Injury Scale and who underwent US, CEUS, and CE-MDCT. Inclusion criteria were: male or female, aged 0-16, hemodynamically stable patients with a history of minor blunt abdominal trauma. Exclusion criteria were adulthood, hemodynamical instability, history of major trauma. Sensitivity, specificity, PPV, NPV, and accuracy were determined for US and CEUS compared to MDCT. RESULTS 6/73 patients were negative at US, CEUS, and MDCT for the presence of organ injuries. In the remaining 67 patients, US depicted 26/67 parenchymal lesions. CEUS identified 67/67 patients (67/67) with parenchymal lesions: 21 lesions of the liver (28.8 %), 26 lesions of the spleen (35.6 %), 7 lesions of right kidney (9.6 %), 13 lesions of left kidney. MDCT confirmed all parenchymal lesions (67/67). Thus, the diagnostic performance of CEUS was better than that of US, as sensitivity, specificity, PPV, NPV, and accuracy were 100, 100, 100, 100, and 100 % for CEUS and 38.8, 100, 100, 12.8, and 44 % for US. In some patients CEUS identified also prognostic factors as parenchymal active bleeding in 8 cases, partial devascularization in 1 case; no cases of vascular bleeding, no cases of urinoma. MDCT confirmed all parenchymal lesions. Parenchymal active bleeding was identified in 16 cases, vascular bleeding in 2 cases, urinoma in 2 cases, partial devascularization in 1 case. CONCLUSIONS CEUS is more sensitive and accurate than baseline US and almost as sensitive as CT in the identification and characterization of solid organs lesions in blunt abdominal trauma. CT is more sensitive and accurate than CEUS in identifying prognostic indicators, as active bleeding and urinoma. CEUS should be considered as a useful tool in the assessment and monitoring of blunt abdominal trauma in children.

Abstract
PURPOSE With increasing concerns about radiation exposure, we questioned whether a structured program of FAST might decrease CT use. METHODS All pediatric trauma surgeons in our level 1 pediatric trauma center underwent formal FAST training. Children with potential abdominal trauma and no prior imaging were prospectively evaluated from 10/2/09 to 7/31/11. After physical exam and FAST, the surgeon declared whether the CT could be eliminated. RESULTS Of 536 children who arrived without imaging, 183 had potential abdominal trauma. FAST was performed in 128 cases and recorded completely in 88. In 48% (42/88) the surgeon would have elected to cancel the CT based on the FAST and physical exam. One of the 42 cases had a positive FAST and required emergent laparotomy; the others were negative. The sensitivity of FAST for injuries requiring operation or blood transfusion was 87.5%. The sensitivity, specificity, PPV, and NPV in detecting pathologic free fluid were 50%, 85%, 53.8%, and 87.9%. CONCLUSIONS True positive FAST exams are uncommon and would rarely direct management. While the negative FAST would have potentially reduced CT use due to practitioner reassurance, this reassurance may be unwarranted given the test's sensitivity.

Abstract
OBJECTIVES As the use of bedside ultrasound becomes more prevalent in pediatric emergency departments, the need for a national curriculum for fellows' training in pediatric emergency medicine (PEM) has increased. The objectives of this study were to describe the current state of bedside ultrasound education among existing PEM fellowship programs and to explore the interest in a national curriculum. METHODS A 20-question survey was sent to all 57 PEM fellowship directors in the United States in February 2011. Weekly reminders were sent for 4 weeks. RESULTS The response rate was 58% (33/57). Although 91% of respondents reported having an ultrasound machine available, only 16% reported an ultrasound curriculum designed specifically for PEM. Another 25% reported no curriculum, and 28% use a curriculum designed for general emergency medicine physicians. Most (>83%) directors thought an ultrasound curriculum for PEM fellows should include the focused assessment with sonography for trauma, bladder size assessment, soft tissue foreign body localization, skin and soft tissue infection evaluation, guidance for central and peripheral line insertion, and arthrocentesis. Some directors (40%-68%) thought that cardiac ultrasound, thoracic ultrasound, abdominal ultrasound, lumbar puncture guidance, fracture reduction, nerve blocks, and testicular ultrasounds should also be included. Forty-two percent plan to create a bedside ultrasound curriculum in the next 5 years, and 40% reported the lack of a national curriculum as a barrier to creating a curriculum. CONCLUSIONS Bedside ultrasound use in pediatric emergency departments is very common, and PEM fellowship directors would welcome the development of a standard curriculum.

Abstract
Pediatric trauma is usually a nonoperative experience for the pediatric general surgeon. The pediatric trauma surgeon resuscitates the child and then evaluates and triages the identified injuries. A common diagnostic tool is the computed tomography (CT) scan. Most children who require evaluation for significant trauma will get a CT scan, but there are no national guidelines directing the assessment. Injuries to the head, cervical spine, chest, and abdomen can all be imaged with a CT scan; the question is whether the liberal approach to imaging children is appropriate. Over the past decade, concern has arisen about the radiation dose delivered by CT. This concern has generated a national campaign to "image gently." This article reviews the data involving the risk of medical radiation exposure and discusses strategies for managing the risk.

Abstract
PURPOSE Focused abdominal sonography for trauma (FAST) has been popularized for the initial evaluation of trauma patients. We sought to understand the scope of practice on a national level with specific attention to its use in the pediatric age group. METHODS An electronic survey was sent to all American College of Surgeons level I trauma centers and the National Association of Children's Hospitals and Related Institutions that were freestanding children's hospitals. RESULTS The survey was emailed to 124 centers, and 98 (79%) completed the survey. Of the surveyed centers, 23% cared for adults only, 28% were freestanding children's hospitals, and 49% managed both. At adults-only institutions, 96% use FAST and at children's hospitals, only 15%; it is used at 85% of centers that care for both. For the centers that use FAST on children, 88% have no age limit. Of all the institutions that typically use FAST, the individual performing the examination could be a surgeon (73%), an emergency department doctor (48%), or a radiologist (3%). Of the centers that perform FAST, 51% bill for the FAST examination. CONCLUSIONS Adult hospitals are much more likely to perform FAST examinations in the trauma patient, and many adult centers routinely use FAST to examine pediatric patients.

Abstract
OBJECTIVES Abdominal trauma is relatively uncommon in children but can be the source of significant morbidity and mortality. The diagnosis and treatment of blunt abdominal injury to the solid organs were examined, and the differences between children and adults were highlighted. METHODS The PubMed database was used to identify the relevant literature. Additional source material was identified through referenced articles. RESULTS Identification of injury to the solid organs in children depends on a high index of suspicion, abnormal physical examination findings, and the judicious use of laboratory and imaging studies. Although abdominal and pelvic computed tomography with intravenous contrast remains the gold standard for imaging, it does expose children to a significant dose of radiation. Currently, more than 90% of solid organ injuries in children are treated nonoperatively. Abnormal hemodynamics, however, suggests active bleeding and requires operative intervention. Accurate diagnosis of the organ injured and degree of injury are important considerations for "return to play" decisions. The management of pancreatic ductal injuries is somewhat controversial, although the distal spleen preserving pancreatectomy is frequently the technique of choice. CONCLUSIONS Pediatric intra-abdominal solid organ injury is relatively uncommon, but a potential source of significant morbidity. Non-operative management is the standard of care for the majority of these injuries, although continued hemodynamic instability mandates operative intervention.

Abstract
The objective of this study was to evaluate the concordance of US and contrast-enhanced US (CEUS) with CT in the assessment of solid organ injury following blunt trauma. Patients underwent complete US examination, including free fluid search and solid organ analysis. CEUS followed, using low-mechanical index techniques and SonoVue. CT was performed within 1 h. Among 156 enrolled patients, 91 had one or more abnormalities (n = 107) at CT: 26 renal, 38 liver, 43 spleen. Sensitivity, specificity, and accuracy for renal trauma at baseline US were 36%, 98%, and 88%, respectively, after CEUS values increased to 69%, 99%, and 94%. For liver baseline US values were 68%, 97%, and 90%; after CEUS were 84%, 99%, and 96%. For spleen, results were 77%, 96%, and 91% at baseline US and 93%, 99%, and 97% after CEUS. Per patient evaluation gave the following results in terms of sensitivity, specificity and accuracy: 79%, 82%, 80% at baseline US; 94%, 89%, and 92% following CEUS. CEUS is more sensitive than US in the detection of solid organ injury, potentially reducing the need for further imaging. False negatives from CEUS are due to minor injuries, without relevant consequences for patient management and prognosis.

Abstract
BACKGROUND The current standard for the evaluation of children with blunt abdominal trauma (BAT) consists of physical examination, screening lab values, and computed tomography (CT) scan. We sought to determine if the focused assessment with sonography for trauma (FAST) combined with elevated liver transaminases (AST/ALT) could be used as a screening tool for intra-abdominal injury (IAI) in pediatric patients with BAT. METHODS Registry data at a level 1 trauma center was retrospectively reviewed from 1991-2007. Data collected on BAT patients under the age of 16 y included demographics, injury mechanism, ISS, GCS, imaging studies, serum ALT and AST levels, and disposition. AST and ALT were considered positive if either one was >100 IU/L. RESULTS Overall, 3171 cases were identified. A total of 1008 (31.8%) patients received CT scan, 1148 (36.2%) had FAST, and 497 (15.7%) patients received both. Of the 497 patients, 400 (87.1%) also had AST and ALT measured. FAST was 50% sensitive, 91% specific, with a positive predictive value (PPV) of 68%, negative predictive value (NPV) of 83%, and accuracy of 80%. Combining FAST with elevated AST or ALT resulted in a statistically significant increase in all measures (sensitivity 88%, specificity 98%, PPV 94%, NPV 96%, accuracy 96%). CONCLUSIONS FAST combined with AST or ALT > 100 IU/L is an effective screening tool for IAI in children following BAT. Pediatric patients with a negative FAST and liver transaminases < 100 IU/L should be observed rather than subjected to the radiation risk of CT.

Abstract
Nonoperative management of blunt splenic injury allows preservation of the immune function of the spleen while avoiding unnecessary laparotomy. The aim of our study was to evaluate the feasibility and the results of conservative management of adult blunt splenic trauma in the context of a developing country. Nonoperative management was proposed for 52 out of 62 patients with blunt splenic trauma treated at the Casablanca University Hospital, Morocco. Motor vehicle-road accidents (88%) were the most common etiology. Multiple trauma was present in 79% of the cases. 15% of the cases had hemodynamic instability. Ultrasonography was performed in 52 patients; it showed splenic contusion in 45 patients and subcapsular hematoma in 7 patients. CT scan showed splenic contusion in 11 patients. Four cases ultimately required operative management with one death. Of the remaining 48 patients, 45 had an uneventful course with observation, but there were two deaths in the observation group.

Abstract
Bedside US has emerged as a valuable technology for the emergency department physician. It impacts clinical decision-making and the safety of procedures, and it decreases the time and increases the efficiency for completion of procedures. The portability, accuracy and noninvasive nature of US make it an ideal tool for the trained clinician. Bedside US can improve clinical decision-making for the pediatric patient by helping the clinician to identify critical pathology, direct therapeutic maneuvers and determine the futility of resuscitations. Many pediatric procedures, such as vascular access, lumbar puncture and bladder catheterization, are typically performed blindly. Bedside US enhances the success of procedures, minimizes complications and limits the number of attempts necessary to complete a procedure. Bedside US can be a valuable adjunct for complicated and time-sensitive disease processes such as ectopic pregnancy, testicular torsion and hypovolemia by providing information to guide diagnostic and therapeutic interventions that subsequently improve outcomes.

Abstract
Abdominal trauma is a common cause of death particularly in patients up to 40 years of age. In order to reduce mortality a rapid radiologic diagnosis is essential. At present, sonography plays a role only in the evaluation of minor trauma and as a "focused assessment with sonography for trauma" (FAST) to clarify free intraperitoneal fluid immediately on admittance in severely injured patients. However, computed tomography has proven to be a potent tool for the triage of patients with abdominal trauma, because, based on the results of the CT scan, patients can be referred for laparotomy or safely classified for "wait and see" treatment. Therapeutic decisions are largely based on injury severity scores and the radiologist must be familiar with them as well as with the associated therapeutic consequences.

Abstract
Bedside emergency ultrasound has been used by emergency physicians for >20 years for a variety of conditions. In adult centers, emergency ultrasound is routinely used in the management of victims of blunt abdominal trauma, in patients with abdominal aortic aneurysm and biliary disease, and in women with first-trimester pregnancy complications. Although its use has grown dramatically in the last decade in adult emergency departments, only recently has this tool been embraced by pediatric emergency physicians. As the modality advances and becomes more available, it will be important for primary care pediatricians to understand its uses and limitations and to ensure that pediatric emergency physicians have access to the proper training, equipment, and experience. This article is meant to review the current literature relating to emergency ultrasound in pediatric emergency medicine, as well as to describe potential pediatric applications.

Abstract
PURPOSE To prospectively compare the sensitivity and specificity of ultrasonography (US) with those of contrast material-enhanced US in the depiction of solid organ injuries in children with blunt abdominal trauma, with contrast-enhanced computed tomography (CT) as the reference standard. MATERIALS AND METHODS The study protocol was approved by the ethics board, and written informed consent was obtained from parents. US, contrast-enhanced US, and contrast-enhanced CT were performed in 27 consecutive children (19 boys, eight girls; mean age, 8.9 years +/- 2.8 [standard deviation]) with blunt abdominal trauma to determine if solid abdominal organ injuries were present. Sensitivity, specificity, agreement, accuracy, number of lesions correctly identified, and positive and negative predictive values were determined for US and contrast-enhanced US, as compared with contrast-enhanced CT. RESULTS In 15 patients, contrast-enhanced CT findings were negative. Contrast-enhanced CT depicted 14 solid organ injuries in 12 patients. Lesions were in the spleen (n = 7), liver (n = 4), right kidney (n = 1), right adrenal gland (n = 1), and pancreas (n = 1). Contrast-enhanced US depicted 13 of the 14 lesions in 12 patients with positive contrast-enhanced CT findings and no lesions in the patients with negative contrast-enhanced CT findings. Unenhanced US depicted free fluid in two of 15 patients with negative contrast-enhanced CT findings and free fluid, parenchymal lesions, or both in eight of 12 patients with positive contrast-enhanced CT findings. Overall, the diagnostic performance of contrast-enhanced US was better than that of US, as sensitivity, specificity, and positive and negative predictive values were 92.2%, 100%, 100%, and 93.8%, respectively. CONCLUSION Contrast-enhanced US was almost as accurate as contrast-enhanced CT in depicting solid organ injuries in children.

Abstract
OBJECTIVE The objective of the study was to obtain the best estimates of the test performance of abdominal ultrasonography (US) for identifying children with intraabdominal injuries (IAIs). METHODS We gathered studies on the use of abdominal US in injured children from the following sources: a MEDLINE and Embase search, hand searches of 5 specialty journals and 4 clinical textbooks, the bibliographies of all identified articles, and contact with experts. Both prospective and retrospective studies were included if they used abdominal US for the detection of intraperitoneal fluid or IAIs in blunt trauma patients less than 18 years of age. All authors independently abstracted data from the selected studies. Disagreements between abstractors were resolved by mutual agreement. RESULTS Twenty-five articles met the inclusion criteria, and 3838 children evaluated with abdominal US were included. Abdominal US had the following test characteristics for identifying children with hemoperitoneum: sensitivity, 80% (95% confidence interval [CI] 76%-84%); specificity, 96% (95% CI 95%-97%); positive likelihood ratio, 22.9 (95% CI 17.2-30.5); and negative likelihood ratio, 0.2 (95% CI 0.16-0.25). Using the most methodologically rigorous studies, however, yielded the following test characteristics of abdominal US for identifying children with hemoperitoneum: sensitivity, 66% (95% CI 56%-75%); specificity, 95% (95% CI 93%-97%); positive likelihood ratio, 14.5 (95% CI 9.5-22.1); and negative likelihood ratio, 0.36 (95% CI 0.27-0.47). CONCLUSIONS Abdominal US has a modest sensitivity for the detection of children with hemoperitoneum; however, its test performance characteristics worsen when only the most methodologically rigorous articles are included. A negative US examination has questionable utility as the sole diagnostic test to rule out the presence of IAI. Because of the high risk of IAI, a hemodynamically stable child with a positive US examination should immediately undergo abdominal computed tomographic scanning.

Abstract
A new field, termed emergency ultrasound (EUS), has recently been established. The past decade saw rapid development in the field of EUS in adult patients, especially as performed by emergency medicine physicians. Ultrasound imaging offers several advantages over traditional radiographic techniques, many of which are especially relevant to patients in the pediatric emergency department. Recent literature has documented increased use of EUS for pediatric patients. This review will examine basic principles of ultrasound relevant to pediatric emergency medicine physicians. Emphasis will be placed on understanding the instrument and its limitations. In addition, we will review recent developments in this field. It is our goal that the reader will gain an understanding of the strengths and limitations of this instrument and will therefore be in a position to plan their own program in EUS in pediatrics. Furthermore, it is hoped that this review will serve as an impetus for innovative research, to refine and extend the indications of this modality to benefit patients in the pediatric emergency department.

[PMID: 15982655 DOI: 10.1016/j.injury.2005.02.026] [Citation(s) in RCA: 66] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2004] [Revised: 02/16/2005] [Accepted: 02/23/2005] [Indexed: 02/02/2023]
Abstract
AIM To study the diagnostic accuracy and clinical efficacy of surgeon-performed focused abdominal sonography (FAST) in paediatric blunt abdominal trauma (BAT). MATERIALS AND METHOD This was a prospective, single blinded study conducted at The Children's Hospital at Westmead Sydney (CHW). All patients with BAT that justified a trauma call activated on presentation to the Emergency Department (ED) had a FAST performed by the Trauma Fellow. The attending surgical team was blinded to the result of the FAST. An independent radiologist reviewed the FAST pictures, and the findings were compared with computerised tomography (CT), ultrasound (US), laparotomy and the clinical outcome of the patient. Sensitivity, specificity and predictive values were calculated. RESULTS A total of 85 patients (39 M; 26 F) were enrolled in the study between February 2002 and January 2003. The age ranged between 4 months and 16 years. The mean Injury Severity Score (ISS) was 6 (range 1-38). FAST was performed in a mean time of 3 min. Inter-rater agreement was 96%. FAST was positive in nine as confirmed by a CT scan of the abdomen. Three patients underwent laparotomy, two for bowel injuries and one for a Grade III liver laceration. Of the remaining 76, 19 had a CT, which showed evidence of intra-abdominal injury in seven patients. There were two false negative studies resulting in a sensitivity of 81%, specificity of 100%, negative predictive value of 97%, positive predictive value of 100% and an accuracy of 97%. CONCLUSIONS Surgeon-performed FAST for BAT was safe and accurate with a high specificity. It would seem a potentially valuable tool in the evaluation of paediatric blunt trauma victims for free fluid within the peritoneal cavity.

Abstract
PURPOSE To study whether compliance with methodological standards affected the reported accuracy of screening ultrasonography (US) for trauma. MATERIALS AND METHODS Meta-analysis was conducted of prospective investigations in which US was compared with any diagnostic reference test in patients with suspected abdominal injury. Reports were retrieved from electronic databases without language restrictions; added information was gained with manual search. Two reviewers independently assessed methodological rigor by using 27 items contained in the Standards for Reporting of Diagnostic Accuracy (STARD) checklist and the Quality Assessment of Studies of Diagnostic Accuracy included in Systematic Reviews (QUADAS) instrument. Inconsistencies were resolved by means of consensus. Summary receiver operating characteristics and random-effects meta-regression were used to model the effect of methodological standards and other study features on US accuracy. RESULTS A total of 62 trials, which included a total of 18,167 participants, were eligible for meta-analysis. The average proportion of men or boys was 71.7%, the mean age was 30.6 years +/- 10.8 (standard deviation), and the mean injury severity score was 16.7 +/- 8.3. The prevalence of abdominal trauma was 25.1% (95% confidence interval [CI]: 21.1%, 29.1%). Pooled overall sensitivity and specificity of US were 78.9% (95% CI: 74.9%, 82.9%) and 99.2% (95% CI: 99.0%, 99.4%), respectively. Varying end points (hemoperitoneum or organ damage) did not change these results. US accuracy was much lower in children (sensitivity, 57.9%; specificity, 94.3%). Strong heterogeneity was observed in sensitivity, whereas specificity remained constant across trials. There was evidence of publication bias. Initial interobserver agreement with methodological standards ranged from poor (kappa = 0.03, independent verification of US findings) to perfect (kappa = 1.00, sufficiently short interval between US and reference test). By consensus, studies fulfilled a median of 13 methodological criteria (range, five to 20 criteria). In investigations that lacked individual methodological standards, researchers overestimated pooled sensitivity, with predicted differences of 9%-18%. The use of a single reference test, specification of the number of excluded patients, and calculation of CIs independently contributed to predicted sensitivity in a multivariate model. In 16 investigations (1309 subjects), a single reference test was used, which provided a combined sensitivity of 66.0% (95% CI: 56.2%, 75.8%). CONCLUSION Bias-adjusted sensitivity of screening US for trauma is low. Adherence to methodological standards included in appraisal instruments like STARD and QUADAS is crucial to obtain valid estimates of test accuracy.

Abstract
PURPOSE In this prospective study we aimed to investigate the diagnostic value of ultrasonography (US) in hemodynamically stable children after blunt abdominal trauma (BAT) using computed tomography (CT) as the gold standard. MATERIALS AND METHODS Between 1997 and 2001, 96 children with BAT were evaluated prospectively. CT was performed first, followed by US. US and CT examinations were independently evaluated by two radiologists for free fluid and organ injury. The sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy of US were assessed regarding CT as the gold standard. RESULTS Overall 128 organ injuries were determined in 96 patients with CT; however, 20 (15.6%) of them could not be seen with US. Free intraabdominal fluid (FIF) was seen in 82 of 96 patients by CT (85.4%) and eight of them (9.7%) could not be seen by US. We found that sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy of the US for free intra-abdominal fluid were 90.2, 100, 100, 63.6 and 91.7%, respectively. CONCLUSIONS US for BAT in children is highly accurate and specific. It is highly sensitive in detecting liver, spleen and kidney injuries whereas its sensitivity is moderate for the detection of gastrointestinal tract (GIT) and pancreatic injuries.

Abstract
OBJECTIVE The purpose of this study was to report our initial experience in the assessment of liver trauma with real-time contrast-enhanced sonography (CES). METHODS From January 2000 to December 2003, there were 431 hemodynamically stable patients evaluated with sonography for blunt abdominal trauma. Among these patients, 87 were selected to undergo second-level imaging, consisting of CES and computed tomographic (CT) evaluation. Indications for further assessment were baseline sonographic findings positive for liver injury, baseline sonographic findings positive for injury to other abdominal parenchyma, baseline sonographic findings positive for free fluid only, baseline sonographic findings indeterminate, and baseline sonographic findings negative with persistent clinical or laboratory suspicion. RESULTS There were 23 hepatic lesions shown by CT in 21 patients. Peritoneal or retroperitoneal fluid was identified in 19 of 21 positive cases by all 3 imaging modalities. Liver injury was found in 15 patients on sonography and in 19 on CES. Contrast-enhanced sonography compared better than unenhanced sonography with the criterion standard for related injury conspicuity, injury size, completeness of injury extension, and involvement of the liver capsule. Both CES and CT showed intrahepatic contrast material pooling in 2 cases. All patients with false-negative sonographic or CES findings recovered uneventfully. CONCLUSIONS Contrast-enhanced sonography is an effective tool in the evaluation of blunt hepatic trauma, being more sensitive than baseline sonography and correlating better than baseline sonography with CT findings. In institutions where sonography is regarded as the initial procedure to screen patients with trauma, this technique may increase its effectiveness. In addition, CES may be valuable in the follow-up of patients with conservatively treated liver trauma.

Abstract
INTRODUCTION Approximately one third of stable patients with significant intra-abdominal injury do not have significant intraperitoneal blood evident on admission. We hypothesized that a delayed, repeat ultrasound study (Secondary Ultrasound--SUS) will reveal additional intra-abdominal injuries and hemoperitoneum. METHODS We performed a prospective observational study of trauma patients at our Level I trauma center from April 2003 to December 2003. Patients underwent an initial ultrasound (US), followed by a SUS examination within 24 hours of admission. Patients not eligible for a SUS because of early discharge, operative intervention or death were excluded. All US and SUS exams were performed and evaluated by surgical/emergency medicine house staff or surgical attendings. RESULTS Five hundred forty-seven patients had both an initial US and a SUS examination. The sensitivity of the initial US in this patient population was 31.1% and increased to 72.1% on SUS (p < 0.001) for intra-abdominal injury or intra-abdominal fluid. The specificity for the initial US was 99.8% and 99.8% for SUS. The negative predictive value was 92.0% for the initial US and increased to 96.6% for SUS (p = 0.002). The accuracy of the initial ultrasound was 92.1% and increased to 96.7% on the SUS (p < 0.002). No patient with a negative SUS after 4 hours developed clinically significant hemoperitoneum. CONCLUSION A secondary ultrasound of the abdomen significantly increases the sensitivity of ultrasound to detect intra-abdominal injury.
