RESUMO
INTRODUCTION: Contrast-enhanced computed tomography (CT) scans are usually needed in the emergency department (ED) to evaluate intra-abdominal injuries associated with pelvic fractures. Three-dimensional (3-D) images for pelvis reconstruction are also needed for planning surgical fixation after admission. This study investigates the advantages integrating a one-stage computed tomography (CT) scan with these two diagnostic modalities simultaneously to reduce the time to surgery and improve the outcomes of pelvic fracture fixation. METHODS: A retrospective cohort study (2018-2021) of patients with pelvic fractures was performed. Patients were categorized into the one-stage CT group or the two-stage CT group, and propensity score matching was used to address biases. The outcome measures included time to surgical fixation, time to CT scan for 3-D pelvis reconstruction, and overall length of hospital stay. RESULTS: Four hundred forty-four pelvic fracture patients who underwent definite surgical fixation were identified. Of those, 320 underwent a one-stage CT scan, while the remaining 124 underwent a two-stage CT scan. After well-balanced matching, those in the one-stage CT group had a significantly shorter time to surgical fixation than those in the two-stage CT group (4.6 vs. 6.8 days, p < 0.001). Even among critically ill patients necessitating intensive care unit (ICU) admission, the one-stage CT scan group had a shorter time to definitive surgical fixation (5.5 vs. 7.2 days, p = 0.002) and a shorter hospital stay (19.0 vs. 32.7 days, p = 0.006). CONCLUSION: A one-stage contrast-enhanced CT scan combined with simultaneous 3-D pelvis reconstruction is promising for expediting surgical fixation in pelvic fracture patients. This innovative strategy may improve patient outcomes by facilitating timely surgical interventions and minimizing delays associated with additional CT scans.

PURPOSE: The impact of transarterial embolization (TAE) and nephrectomy on acute kidney injury (AKI) in blunt renal trauma patients remains unclear, and we used the National Trauma Data Bank (NTDB) to investigate this issue. METHODS: Adult patients from the NTDB between 2007 and 2015 who survived traumatic events with blunt injuries were eligible for inclusion. The exclusion criteria were those without outcome information, who required dialysis, or with chronic renal failure prior to the traumatic injury. Patients sustaining hepatic, splenic, or pelvic fractures or who had bilateral nephrectomy were also excluded. The patients were divided into three treatment groups, including conservative treatment, TAE, and nephrectomy. Two statistical models, logistic regression (LR) and inverse probability treatment weighting (IPTW), were used to clarify the AKI predictors. RESULTS: The study included 10,096 patients. There were 9697 (96.0%), 202 (2.0%) and 197 (2.0%) patients in the conservative, TAE and nephrectomy groups, respectively. Nephrectomy was a statistically significant predictor of AKI in blunt renal trauma patients in the standard LR (odds ratio [OR], 4.58; 95% confidence interval [CI] 1.92-10.38; p < 0.001) and IPTW (OR, 5.16; 95% CI 1.07-24.85; p = 0.023) models. In addition, TAE was not a risk factor for AKI in blunt renal trauma patients (p > 0.05 in all models). CONCLUSION: AKI is less likely affect patients with blunt renal trauma with TAE than those with nephrectomy. Nephrectomy is a risk factor for AKI in blunt renal trauma patients. TAE should be considered first when blunt renal trauma patients need a hemostatic procedure.

PURPOSE: Most blunt thoracic aortic injuries (BTAIs) may be treated using thoracic endovascular aortic repair (TEVAR), and most blunt abdominal traumas (BATs) are managed conservatively. We hypothesized that severe trauma that needs TEVAR may increase the risk of delayed intra-abdominal hemorrhage in patients with concomitant BTAI and BAT because of the potential hemorrhagic shock, disseminated intravascular coagulopathy, blood loss, consequent need for blood transfusion, and procedure-associated heparinization. MATERIALS AND METHODS: From 2015 to 2019, blunt trauma patients with concomitant severe chest trauma and abdominal trauma who could be managed conservatively were studied. The probability of delayed intra-abdominal hemorrhage was compared between patients with concomitant BTAI who received or did not undergo TEVAR. Propensity score matching (PSM), inverse probability of treatment weighting (IPTW), and multivariate logistic regression (MLR) were used to eliminate discrepancies between these 2 groups. RESULTS: Among the 341 studied patients, there were 26 patients with BTAI, and 19 of them underwent TEVAR. Delayed intra-abdominal hemorrhage was observed in 4 patients (21.1%, 4/19) who underwent TEVAR. Both PSM and IPTW showed that patients who underwent TEVAR for concomitant BTAI had a greater delayed need for blood transfusions and a larger proportion of delayed intra-abdominal hemorrhage than patients who did not undergo the procedure. The MLR analysis showed that TEVAR for BTAI was an independent risk factor for delayed intra-abdominal hemorrhage (odds ratio: 10.534, 95%, p<0.001). CONCLUSION: An increased probability of delayed intra-abdominal hemorrhage in patients with BAT (who could be managed conservatively) was observed in patients who underwent TEVAR for concomitant BTAI. CLINICAL IMPACT: More attention should be give in patients with high grade aortic injuries and concomitant abdominal trauma.
RESUMO
BACKGROUND: Acute cholecystitis (AC) is a common surgical emergency. The Tokyo Guidelines 2018 (TG18) provides a reliable algorithm for the treatment of AC patients to achieve optimal outcomes. However, the economic benefits have not been validated. We hypothesize that good outcomes and cost savings can both be achieved if patients are treated according to the TG18. METHOD: This retrospective study included 275 patients who underwent cholecystectomy in a 15-month span. Patients were divided into three groups (group 1: mild AC; group 2: moderate AC with American Society of Anesthesiologists (ASA) physical status class ≤ 2 and Charlson Comorbidity Index (CCI) score ≤ 5; and group 3: moderate AC with ASA class ≥ 3, CCI score ≥ 6, or severe AC). Each group was further divided into two subgroups according to management (followed or deviated from the TG18). Patient demographics, clinical outcomes, and hospital costs were compared. RESULTS: For group 1 patients, 77 (81%) were treated according to the TG18 and had a significantly higher successful laparoscopic cholecystectomy (LC) rate (100%), lower hospital cost ($1896 vs $2388), and shorter hospital stay (2.9 vs 8 days) than those whose treatment deviated from the TG18. For group 2 patients, 50 (67%) were treated according to the TG18 and had a significantly lower hospital cost ($1926 vs $2856), shorter hospital stay (3.9 vs 9.9 days), and lower complication rate (0% vs 12.5%). For group 3 patients, 62 (58%) were treated according to the TG18 and had a significantly lower intensive care unit (ICU) admission rate (9.7% vs 25%), but a longer hospital stay (12.6 vs 7.8 days). However, their hospital costs were similar. Early LC in group 3 patients did not have economic benefits over gallbladder drainage and delayed LC. CONCLUSION: The TG18 are the state-of-the-art guidelines for the treatment of AC, achieving both satisfactory outcomes and cost-effectiveness.

BACKGROUND: Conventionally, pelvic fracture-related acute retroperitoneal hemorrhage (ARH) is life threatening and difficult to control. However, the use of angioembolization to treat fracture-associated ARH improves the hemodynamic stability of patients with pelvic fractures. The role of angioembolization in the management of patients with pelvic fracture-related ARH was examined. MATERIALS AND METHODS: We retrospectively reviewed a large case series of patients with pelvic fractures between January 2010 and December 2014. Comparisons were made between patients with and without ARH. In addition, the characteristics of mortality were delineated, whereas the causes of death in patients with pelvic fracture were discussed and analyzed. RESULTS: A total of 1070 patient records were reviewed during the 60-month study period, and the overall mortality rate of pelvic fracture was 7.7% (82/1070). However, there were only seven patients who died due to uncontrolled ARH (0.7%). The patients with ARH had more injuries to other organs than did the patients without ARH (head: 79.7% vs. 31.7%, pâ¯<â¯0.001; chest: 50.3% vs. 10.9%, pâ¯<â¯0.001; abdomen: 72.0% vs. 22.7%, pâ¯<â¯0.001; spine: 12.6% vs. 4.4%, pâ¯<â¯0.001; extremities: 69.2% vs. 44.3%, pâ¯<â¯0.001). CONCLUSION: The treatment for pelvic fracture patients declared dead upon arrival remains limited. However, pelvic fracture-related ARH could be controlled effectively with angioembolization. In addition to ARH, injuries to other organs may play a key role in the mortality of patients with pelvic fractures.

INTRODUCTION: Managing patients with open pelvic fractures continues to be challenging and requires a multidisciplinary approach. In this study, we examined the characteristics of patients with open pelvic fractures and strategies for managing such patients. MATERIALS AND METHODS: The records of patients with open pelvic fractures from January 2010 to August 2016 were retrospectively reviewed. Emergency surgery was performed to control hemorrhaging in patients with an active external hemorrhage. Transcatheter arterial embolization (TAE) was used for definitive hemostasis. The relation between cause of death and timing of death was examined. We also compared the characteristics of surviving and non-surviving patients. Furthermore, patients who received both surgery and post-operative TAE were analyzed in detail. RESULTS: In total, 42 patients with open pelvic fractures were enrolled in the study. The overall mortality rate among patients with open pelvic fractures was 26.2%. Patients whose deaths were related to hemorrhaging and associated injuries died significantly earlier than patients whose deaths were related to sepsis and multiple organ failure (1.3days vs. 12.3days, p<0.001). Sixteen patients (38.1%) received TAE for hemostasis, and their systolic blood pressure (SBP) improved significantly following TAE (from 88.4mmHg to 111.6mmHg, p<0.05). In the patients who received both surgery and post-operative TAE (n=8), the SBP increased significantly after surgery (from 58.8mmHg to 81.1mmHg, p<0.05). Similarly, the patients' SBP after TAE was significantly higher than their post-operative SBP (110.5mmHg vs. 81.1mmHg, p<0.05). CONCLUSION: Active external hemorrhaging was initially controlled when managing patients with open pelvic fractures; however, most patients also required TAE for definitive hemorrhage control. Early TAE should be considered due to the high probability of concomitant internal and external hemorrhage. Close observation and further infection control are important following the hemostatic procedure.

BACKGROUND: Venous thromboembolism (VTE), including deep venous thrombosis (DVT) and pulmonary embolism (PE), is a common complication of major trauma. Pharmacological VTE prophylactics are widely used, and low-molecular-weight heparin (LMWH) is recommended. Factor Xa inhibitors are increasingly being used for VTE prophylaxis in both medical and surgical patients. Evidence comparing LMWH and factor Xa inhibitors as VTE prophylactics for severe blunt trauma is lacking. This study aims to compare the efficacy and safety of factor Xa inhibitors and LMHW in VTE prophylaxis. MATERIALS AND METHODS: Patients with severe blunt trauma who received LMWH or a factor Xa inhibitor for VTE prophylaxis in the Trauma Quality Improvement Program between 2017 and 2019 were included. The comparison was performed after using propensity score matching. The outcomes included mortality and incidence of DVT, PE, post-prophylactics haemorrhage control procedures and length of stay. RESULTS: After 2:1 propensity score matching, 1128 patients ( n =752, LMHW group; n =376, factor Xa inhibitor group) were included in the analysis. Patients in the LMWH group had fewer VTE events than those in the factor Xa inhibitor group (DVT, 3.7% vs. 7.2%, P =0.013; PE, 0.4% vs. 3.2%, P <0.001). VTE risk was higher in the factor Xa group (DVT: odds ratio, 1.97; 95% CI, 1.12-3.44; P =0.018 and PE: odds ratio, 9.65; 95% CI, 2.91-44.12; P =0.001). The mortality rate was higher in the LMWH group; however, there was no significant difference (4.0% vs. 1.9%; P =0.075). The difference in the risk of undergoing haemorrhage control surgery after VTE prophylaxis between both groups was insignificant (0.3% vs. 0.0%; P =0.333). CONCLUSIONS: LMWH was associated with a lower risk of VTE than factor Xa inhibitors in patients with severe blunt trauma. The mortality rate was higher in the LMWH group; however, there was no statistically significant difference observed.

Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) has been an established life-saving procedure for adult trauma patients, but the evidence for its use in pediatric patients is still under question. The purpose of this study was to examine the outcome of REBOA in pediatric patients. Methods: We retrospectively analyzed observational cohort data from the American College of Surgeons-Trauma Quality Improvement Program from 2017 to 2019. We analyzed 183 506 trauma patients aged 7-18, and 111 patients were matched by propensity score analysis. Basic demographics, injury severity, trauma type, and clinical outcomes of the patients receiving REBOA and those not receiving REBOA were compared. In the REBOA patients, a subgroup analysis was performed to evaluate the potential influence of age and body weight on the outcomes of REBOA. Results: After the pretreatment factors were balanced for the REBOA and no-REBOA groups, the patients in the REBOA group had more transfused packed red blood cells within the first 4 hours (3250 mL vs. 600 mL, p<0.001), and the mortality rate was higher in the REBOA group, but it did not reach statistical significance (56.8% vs. 36.5%, p=0.067). No significant difference was detected regarding in-hospital complications. In the subgroup analysis of the patients who received REBOA, we discovered no significant difference in mortality and complications between the subgroups when compared by age (>15 years old/≤15 years old) or weight (>58 kg or ≤58 kg). Conclusions: Pediatric trauma patients who received REBOA were not significantly associated with an increased risk of mortality when compared with no-REBOA patients with matched basic demographics and pretreatment factors. Younger age and lighter body weight did not seem to influence the outcomes of REBOA regarding survival and complications. Level of evidence: Level III.
RESUMO
PURPOSE: This study aimed to elucidate the treatment approach for blunt splenic injuries concurrently involving the aorta. We hypothesized that non-operative management failure rates would be higher in such cases, necessitating increased hemorrhage control surgeries. METHODS: Data from the Trauma Quality Improvement Program spanning 2017 to 2019 were utilized. All patients with blunt splenic trauma were considered for inclusion. We conducted comparisons between blunt splenic trauma patients with and without thoracic or abdominal aortic injuries to identify any potential disparities in treatment. RESULTS: Among the 32,051 patients with blunt splenic injuries during the study period, 752 (2.3%) sustained concurrent aortic injuries. Following 2:1 propensity score matching, it was determined that the presence of aortic injuries did not significantly affect the utilization of splenic transarterial angioembolization (TAE) (7.2% vs. 8.7%, p = 0.243) or the necessity for splenectomy or splenorrhaphy (15.3% vs. 15.7%, p = 0.853). Moreover, aortic injuries were not a significant factor contributing to TAE failure, regardless of the location or severity of the injury. Patients with simultaneous splenic and aortic injuries required more red blood cell transfusion within first 4 hours (0 ml [0, 900] vs. 0 ml [0, 650], p = 0.001) and exhibited a higher mortality rate (10.6% vs. 7.9%, p = 0.038). CONCLUSION: This study demonstrated that patients with concurrent aortic and splenic injuries presented with more severe conditions, higher mortality rates, and extended hospital stays. The presence of aortic injuries did not substantially influence the utilization of TAE or the necessity for splenectomy or splenorrhaphy. Patients of this type can be managed in accordance with current treatment guidelines. Nonetheless, given their less favorable prognosis, they necessitate prompt and proactive intervention.

BACKGROUND: The impact of resuscitative endovascular balloon occlusion of the aorta (REBOA) on traumatic brain injuries remains uncertain, with potential outcomes ranging from neuroprotection to exacerbation of the injury. The study aimed to evaluate consciousness recovery in patients with blunt trauma with shock and traumatic brain injuries. MATERIAL AND METHODS: Data were obtained from the American College of Surgeons Trauma Quality Improvement Program from 2017-2019. During the study period, 3,138,896 trauma registries were examined, and 16,016 adult patients with blunt trauma, shock, and traumatic brain injuries were included. Among these, 172 (1.1%) underwent REBOA. Comparisons were conducted between patients with and without REBOA after implementing 1:3 propensity score matching to mitigate disparities. The primary outcome was the highest Glasgow Coma Scale score during admission. The secondary outcomes encompassed the volume of blood transfusion, the necessity for hemostatic interventions and therapeutic neurosurgery, and mortality rate. RESULTS: Through well-balanced propensity score matching, a notable difference in mortality rate was observed, with 59.7% in the REBOA group and 48.7% in the non-REBOA group (P=0.015). In the REBOA group, the median 4-hour red blood cell transfusion was significantly higher (2800 mL [1500, 4908] vs. 1300 mL [600, 2500], P<0.001). The REBOA group required lesser hemorrhagic control surgeries (31.8% vs. 47.7%, P<0.001) but needed more transarterial embolization interventions (22.2% vs 15.9%, P=0.076). The incidence of therapeutic neurosurgery was 5.1% in the REBOA group and 8.7% in the non-REBOA group (P=0.168). Among survivors in the REBOA group, the median highest Glasgow Coma Scale score during admission was significantly greater for both total (11 [8, 14] vs. 9 [6, 12], P=0.036) and motor components (6 [4, 6] vs. 5 [3, 6], P=0.037). The highest GCS score among the survivors with predominant pelvic injuries was not different between the two groups (11 [8, 13] vs. 11 [7, 14], P=0.750). CONCLUSIONS: Patients experiencing shock and traumatic brain injury have high mortality rates, necessitating swift resuscitation and prompt hemorrhagic control. The use of REBOA as an adjunct for bridging definitive hemorrhagic control may correlate with enhanced consciousness recovery.
RESUMO
Computed tomography (CT) is the most commonly used diagnostic modality for blunt abdominal trauma (BAT), significantly influencing management approaches. Deep learning models (DLMs) have shown great promise in enhancing various aspects of clinical practice. There is limited literature available on the use of DLMs specifically for trauma image evaluation. In this study, we developed a DLM aimed at detecting solid organ injuries to assist medical professionals in rapidly identifying life-threatening injuries. The study enrolled patients from a single trauma center who received abdominal CT scans between 2008 and 2017. Patients with spleen, liver, or kidney injury were categorized as the solid organ injury group, while others were considered negative cases. Only images acquired from the trauma center were enrolled. A subset of images acquired in the last year was designated as the test set, and the remaining images were utilized to train and validate the detection models. The performance of each model was assessed using metrics such as the area under the receiver operating characteristic curve (AUC), accuracy, sensitivity, specificity, positive predictive value, and negative predictive value based on the best Youden index operating point. The study developed the models using 1302 (87%) scans for training and tested them on 194 (13%) scans. The spleen injury model demonstrated an accuracy of 0.938 and a specificity of 0.952. The accuracy and specificity of the liver injury model were reported as 0.820 and 0.847, respectively. The kidney injury model showed an accuracy of 0.959 and a specificity of 0.989. We developed a DLM that can automate the detection of solid organ injuries by abdominal CT scans with acceptable diagnostic accuracy. It cannot replace the role of clinicians, but we can expect it to be a potential tool to accelerate the process of therapeutic decisions for trauma care.

INTRODUCTION: Transarterial embolization (TAE) or nephrectomy for patients with blunt renal trauma might result in acute kidney injury (AKI). Thus, we analyzed the American College of Surgeons - Trauma Quality Improvement Program (TQIP) to validate this. We hypothesized that nephrectomy, and not TAE, would be a risk factor for AKI in patients with blunt renal trauma. MATERIAL AND METHODS: Adult patients with blunt injuries from the TQIP between 2017 and 2019 were eligible for inclusion. The patients were divided into three treatment groups: conservative treatment, TAE, and nephrectomy. Multivariable logistic regression was used to clarify the AKI predictors. RESULTS: The study included 12,843 patients, wherein 12,373 (96.3 %), 229 (1.8 %), and 241 (1.9 %) patients were in the conservative, TAE, and nephrectomy groups, respectively. A total of 269 (2.2 %), 20 (8.7 %), and 29 (12.0 %) patients had AKI in the three groups, respectively. Both TAE (odds ratio [OR], 2.367; 95 % confidence interval [CI], 1.372-3.900; p = 0.001) and Nephrectomy (OR, 2.745; 95 % CI, 1.629-4.528; p < 0.001) were a statistically significant predictor for AKI in the multivariable logistic regression. CONCLUSIONS: TAE and nephrectomy were statistically associated with AKI in patients with blunt renal trauma. This result differs from our previous research findings that nephrectomy, but not TAE, was a risk factor for AKI in patients with blunt renal trauma. Further prospective and well-designed research may be needed.

INTRODUCTION: The optimal time to intramedullary internal fixation for patients with isolated and unilateral femoral shaft fractures was investigated by the American College of Surgeons-Trauma Quality Improvement Program (ACS-TQIP). MATERIAL AND METHODS: Adult patients from the TQIP between 2017 and 2019 were eligible for inclusion. The associations between time to fixation and target outcomes (pulmonary embolism [PE], deep vein thrombosis [DVT], acute respiratory distress syndrome [ARDS], and mortality) were assessed. Maximization of the sum of sensitivity and specificity was used to determine the optimal cut point. The patients were divided into three groups according to different time to fixation intervals. A multinomial propensity scores weighting using generalized boosted models was performed for all unbiased pre-treatment factors between the groups. Multivariate logistic regression was used to clarify the outcomes predictors. RESULTS: The univariate and multivariate analysis before weighting showed that only PE was significantly associated with time to fixation (odds ratio [OR], 1.05; 95% confidence interval [CI], 1.01-1.09; p = 0.012). The optimal cut point of time to fixation was 13.88 h. The patients were divided into accelerated (≤ 13.88 h), standard (> 13.88 and ≤ 24 h), and delayed (> 24 and < 36 h) groups. After weighting for all unbiased pre-treatment factors between the groups, multivariate logistic regression showed that standard group significantly increased the risk of PE compared with accelerated group (OR, 4.436; 95% CI, 1.844-10.672; p = 0.001). CONCLUSION: Accelerated intramedullary internal fixation within 13.88 h was associated with a significantly decreased risk of PE compared with standard fixation in patients with isolated and unilateral femoral shaft fractures without additional mortality risks.

AIMS: This study aimed to assess the effect of zinc supplementation, with or without other antioxidants and trace elements, on clinical outcomes in patients with trauma. METHODS: A systematic review was conducted for adult patients with acute trauma who had been admitted to the hospital. Those who sustained burn injuries were excluded. Studies in PubMed, Web of Science, and Embase from 1990 to 2022 regarding the additional nutrition supplementation of zinc to patients, either in a single-agent or combined regimen, were included. Comparisons were made between the zinc supplement group and those who received a placebo or regular treatment. RESULTS: The primary outcomes of the study were mortality rate, length of hospital stay, and incidence of pneumonia. Seven studies qualified for the meta-analysis. Of the 594 patients eligible for analysis, 290 and 304 were in the zinc supplementation and control groups, respectively. The meta-analysis revealed that zinc supplementation was associated with a lower risk of pneumonia in patients with acute trauma than in the control group (odds ratio [OR], 0.506; 95% CI = 0.292-0.877; P = 0.015; heterogeneity, I2 = 12.7%). Zinc supplementation did not influence the mortality rate (OR, 0.755; 95% CI = 0.492-1.16; P = 0.612; heterogeneity, I2 = 0%) or the length of hospital stay (standard difference in means, -0.24; 95% CI = -0.544 to 0.063; P = 0.121; heterogeneity, I2 = 45.0%). CONCLUSION: Zinc supplementation, with or without other antioxidants and trace elements, in patients with trauma was associated with a lower incidence of pneumonia.

(1) Background: Hip degenerative disorder is a common geriatric disease is the main causes to lead to total hip replacement (THR). The surgical timing of THR is crucial for post-operative recovery. Deep learning (DL) algorithms can be used to detect anomalies in medical images and predict the need for THR. The real world data (RWD) were used to validate the artificial intelligence and DL algorithm in medicine but there was no previous study to prove its function in THR prediction. (2) Methods: We designed a sequential two-stage hip replacement prediction deep learning algorithm to identify the possibility of THR in three months of hip joints by plain pelvic radiography (PXR). We also collected RWD to validate the performance of this algorithm. (3) Results: The RWD totally included 3766 PXRs from 2018 to 2019. The overall accuracy of the algorithm was 0.9633; sensitivity was 0.9450; specificity was 1.000 and the precision was 1.000. The negative predictive value was 0.9009, the false negative rate was 0.0550, and the F1 score was 0.9717. The area under curve was 0.972 with 95% confidence interval from 0.953 to 0.987. (4) Conclusions: In summary, this DL algorithm can provide an accurate and reliable method for detecting hip degeneration and predicting the need for further THR. RWD offered an alternative support of the algorithm and validated its function to save time and cost.
RESUMO
BACKGROUND: Traumatic flail chest results in respiratory distress and prolonged hospital stay. Timely surgical fixation of the flail chest reduces respiratory complications, decreases ventilator dependence, and shortens hospital stays. Concomitant head injury is not unusual in these patients and can postpone surgical timing due to the need to monitor the status of intracranial injuries. Reducing pulmonary sequelae also assists in the recovery from traumatic brain injury and improves outcomes. No previous evidence supports that early rib fixation can improve the outcome of patients with concomitant flail chest and traumatic brain injury. RESEARCH QUESTION: Can early rib fixation improve the outcome of patients with concomitant flail chest and traumatic brain injury? STUDY DESIGN AND METHODS: Adult patients with blunt injuries from the Trauma Quality Improvement Project between 2017 and 2019 were eligible for inclusion. Patients were divided into two treatment groups: operative and nonoperative. Inverse probability treatment weighting was used to identify the predictors of mortality and adverse hospital events. RESULTS: Patients in the operative group had a higher intubation rate [odds ratio (OR), 2.336; 95% CI, 1.644-3.318; p <0.001), a longer length of stay (coefficient ß , 4.664; SE, 0.789; p <0.001), longer ventilator days (coefficient ß , 2.020; SE, 0.528; p <0.001), and lower mortality rate (OR], 0.247; 95% CI, 0.135-0.454; p <0.001). INTERPRETATION: Timely rib fixation can improve the mortality rate of patients with flail chest and a concomitant mild-to-moderate head injury.

BACKGROUND: Splenic injury is the most common solid visceral injury in blunt abdominal trauma, and high-resolution abdominal computed tomography (CT) can adequately detect the injury. However, these lethal injuries sometimes have been overlooked in current practice. Deep learning (DL) algorithms have proven their capabilities in detecting abnormal findings in medical images. The aim of this study is to develop a three-dimensional, weakly supervised DL algorithm for detecting splenic injury on abdominal CT using a sequential localization and classification approach. MATERIAL AND METHODS: The dataset was collected in a tertiary trauma center on 600 patients who underwent abdominal CT between 2008 and 2018, half of whom had splenic injuries. The images were split into development and test datasets at a 4 : 1 ratio. A two-step DL algorithm, including localization and classification models, was constructed to identify the splenic injury. Model performance was evaluated using the area under the receiver operating characteristic curve (AUROC), accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). Grad-CAM (Gradient-weighted Class Activation Mapping) heatmaps from the test set were visually assessed. To validate the algorithm, we also collected images from another hospital to serve as external validation data. RESULTS: A total of 480 patients, 50% of whom had spleen injuries, were included in the development dataset, and the rest were included in the test dataset. All patients underwent contrast-enhanced abdominal CT in the emergency room. The automatic two-step EfficientNet model detected splenic injury with an AUROC of 0.901 (95% CI: 0.836-0.953). At the maximum Youden index, the accuracy, sensitivity, specificity, PPV, and NPV were 0.88, 0.81, 0.92, 0.91, and 0.83, respectively. The heatmap identified 96.3% of splenic injury sites in true positive cases. The algorithm achieved a sensitivity of 0.92 for detecting trauma in the external validation cohort, with an acceptable accuracy of 0.80. CONCLUSIONS: The DL model can identify splenic injury on CT, and further application in trauma scenarios is possible.

INTRODUCTION: The study reviewed the experience of video-assisted thoracoscopic surgery (VATS) for the treatment of massive haemothorax (MHT). MATERIALS AND METHODS: All adult patients who sustained blunt trauma with a diagnosis of traumatic haemothorax or pneumothorax (ICD9 860; ICD10 S27.0-2), injury to the heart and lungs (ICD9 861; ICD10 S26, S27.3-9), and injury to the blood vessels of the thorax (ICD9 901; ICD10 S25) were queried from the trauma registry between 2014 and 2018. Patients who had chest tube drainage amounts meeting the criteria for MHT and who underwent subsequent operations were eligible for analyses. The patients were divided into VATS or thoracotomy groups based on the surgical modalities. Descriptions and analyses of the two groups were made. RESULTS: Thirty-eight patients were enroled in the study, including 8 females (21%) and 30 males. The median age was 47.0 (first quartile (Q1) 25.5 and third quartile (Q3) 59.3) years. Twenty-three patients were in the VATS group, six (26%) of whom were converted to thoracotomy. There were no obvious differences in age, sex, pulse rate, or systolic pressure on arrival to the ED or after resuscitation between the two groups. The laboratory data were worse amongst the thoracotomy group, especially the arterial blood gas analysis (ABG) results: pH 7.2 (7.1, 7.3) vs. 7.4 (7.2, 7.4); HCO3 14.6 (12.4, 18.7) vs. 19.7 (16.1, 23.9) mEq/L; base excess (BE) -12.6 (-15.8, -7.8) vs. -5.2 (-11.1, -0.9) mEq/L. The PaO2/FiO2 ratio was lower in the thoracotomy group (91.4 (68.5, 193.3) vs. 245.3 (95.7, 398.0) mmHg). The thoracotomy group had coagulopathy (INR 1.6 (1.2, 1.9) vs. 1.3 (1.1, 1.4)) and required more blood transfusions (WB and PRBC 36.0 (16.0, 48.0) vs. 12.0 (4.0, 24.0) units; FFP 20.0 (6.0, 50.0) vs. 6.0 (2.0, 20.0) unit). No factors associated with VATS conversion to thoracotomy could be identified. CONCLUSIONS: VATS could be applied to selected blunt trauma patients with MHT. The major differences between the VATS and thoracotomy groups were coagulopathy, acidosis, PaO2/FiO2 ratio < 200 mmHg, or a persistent need for blood transfusion.

BACKGROUND/OBJECTIVE: The present study investigated the impact of splenomegaly on the treatment outcomes of blunt splenic injury patients. METHODS: All blunt splenic injury patients were enrolled between 2010 and 2018. The exclusion criteria were age less than 18 years, missing data, and splenectomy performed at another hospital. The patients were divided into two groups based on the presence of splenomegaly, defined as a spleen length over 9.76 cm on axial computed tomography. The primary outcome was the need for hemostatic interventions. RESULTS: A total of 535 patients were included. Patients with splenomegaly had more high-grade splenic injuries (p = 0.007). Hemostatic treatments (p < 0.001) and transarterial embolization (p = 0.003) were more frequently required for patients with splenomegaly. Multivariate analysis showed that male sex (p = 0.023), more packed red blood cell transfusions (p = 0.001), splenomegaly (p = 0.019) and grade 3-5 splenic injury (p < 0.001) were predictors of hemostatic treatment. The failure rate of transarterial embolization was not significantly different between the two groups (p = 0.180). The sensitivity and specificity for splenomegaly in predicting hemostatic procedures were 48.8% and 66.5%, respectively. The positive and negative predictive values were 62.8% and 52.9%, respectively. The overall mortality rate was 3.7%. CONCLUSION: Splenomegaly is an independent predictor for the requirement of hemostatic treatments in blunt splenic injury patients, especially transarterial embolization. Transarterial embolization is as effective for blunt splenic injury patients with splenomegaly as it is for those with a normal spleen.

BACKGROUND: Hepatocellular carcinoma (HCC) is often diagnosed late because of the lack of pathognomonic symptoms. This study evaluated outcomes following liver resection (LR) for patients with HCC presenting with large tumor size (over 10 cm), adjacent organ invasion, or ruptured tumor, which we termed as complicated HCC (cHCC). MATERIALS AND METHODS: We retrospectively reviewed 660 HCC patients who underwent LR between January 2001 and July 2005. The patients were grouped into cHCC and non-cHCC according to the defined criteria. The clinicopathological features were analyzed and compared between the two groups. RESULTS: Patients in the cHCC group required longer operative times and resulted in greater intraoperative blood loss and more severe surgical complications. The cHCC group had a higher incidence of HCC recurrence after LR, and the HCC recurrence had a tendency to be associated with extrahepatic metastasis. The 5-year RFS (P < 0.0001) and OS (P < 0.0001) of cHCC and non-cHCC patients were 18.5% and 28.9% versus 37.5% and 57.6%, respectively. CONCLUSIONS: LR for cHCC can be a great challenge for liver surgeons. However, with comparable operative mortality rates and acceptable survival times, surgical resection should always be considered performing in patients with cHCC, if clinically feasible.
