Heart injuries following polytrauma (PT) are identified as a predictor of poor outcome. The diagnostic algorithm of cardiac damage after trauma consists of the systemic measurement of cardiac damage markers, a 3-channel ECG and if there are any suspicious findings, the conduction of a transthoracic echocardiography (TTE). The aim of this study was to implement a systematic analysis of cardiac function using TTE in PT-patients. This study is a prospective non-randomized study, conducted in a German Level 1 Trauma Centre between January and July 2024. All polytraumatized patients with an ISS ≥ 16 were included immediately after entering the emergency department. Blood samples were withdrawn at 6 timepoints, at the Emergency room, 24 h, 48 h, three, five and ten days after admission to the hospital. Cardiac damage was measured by Troponin T (TnT) ECLIA, as well as NT-proBNP measurements. Entering the intensive care unit, transthoracic echocardiography was performed at two time points (day 1 and 2), by an experienced Cardiologist. During the pilot phase, cardiac contusion was detected in 14.3% of patients, with significantly elevated TnT levels on arrival, after 24 (**p ≤ 0.01) and 48 h (*p ≤ 0.05) compared to patients without cardiac contusion. Echocardiographic findings revealed that 25% of all patients had wall motion abnormalities, and 20% showed relaxation disorders. Right ventricular function, measured by TAPSE (tricuspid annular plane systolic excursion), RVEDD (right ventricular end diastolic diameter) and sPAP (systolic pulmonary arterial pressure), was slightly impaired in trauma patients, while the left ventricular function (ejection fraction (EF) and left ventricular end diastolic diameter (LVEDD)) was preserved. We observed the increase of TnT and an increase of the heart failure marker NT-proBNP over the time. These biomarkers were associated with pre-existing cardiac risk factors, the ISS and changes in the right or left ventricular function. Mitral valve insufficiency (grade 1) was present in 50% and tricuspid valve (grade 1) insufficiency in 30%. Taken together, we conducted for the first time of our knowledge, a systematic TTE analysis in PT-patients. We observed a slightly reduced right ventricular function, as well as mitral and tricuspid valve regurgitations in the patients.

Emergency laparotomy (EmLap) is a complex clinical arena, delivering time-sensitive, definitive care to a high-risk patient cohort, with significant rates of post-operative morbidity and mortality. Embedding perioperative care pathways within this complex setting has the potential to improve post-operative outcomes, however, requires an in-depth understanding of their design, delivery and outcome assessment. Delivering and implementing complex interventions such as perioperative pathways require transparent reporting with detailed and indepth description of all components during the assessment and evaluation phase. The aim of this systematic review was to identify the current design and reporting of perioperative pathways in the EmLap setting. The OVID SP versions of MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials were searched between January 1950 and December 2023. All randomised and non-randomised cohort studies reporting outcomes on perioperative care pathways in adult patients (> 18 years old) undergoing major emergency abdominal surgery were included. A narrative description of all perioperative pathways included was reported to identify design and description of the pathway including the delivery and timing of component interventions. All pathways were evaluated against the Template for Intervention Description and Replication (TIDieR) checklist. Eleven RCTs and 19 non-randomised studies were identified, with most studies considered to be at moderate risk of bias. Twenty-six unique pathways were identified and described, delivering a total of 400 component interventions across 44,055 patients. Component interventions were classified into 24 domains across the perioperative pathway. Twenty studies (66.6%) did not report the TIDieR framework items, with thirteen studies reporting less than 50% of all items. Two hundred and fifty individual outcomes were reported across pathways, with the most commonly reported outcomes related to morbidity, mortality and length of stay. Current perioperative pathways in EmLap setting are underpinned by variable component interventions, with a lack of in-depth intervention reporting and evaluation. Future studies should incorporate the TIDieR checklist when reporting on perioperative pathways in the EmLap setting. Not applicable.

Coagulopathy, inflammation and organ failure are common complications in trauma patients. This study aimed to explore the possible role of muscle injury indicators in early coagulopathy, systemic inflammatory response syndrome (SIRS), and acute kidney injury (AKI) in patients with severe multiple trauma. A retrospective analysis was performed using trauma center patient data from 2020 to 2023. The incidence of coagulopathy, SIRS and AKI in patients with multiple injuries were assessed. The relationship between Myoglobin, creatine kinase (CK), lactate dehydrogenase (LDH) and trauma severity was investigated, and the influence of these three muscle injury indicators on patient adverse outcomes was analyzed. A total of 312 patients with severe multiple injuries were included in this study, with an average age of 51.7 and a median Injury Severity Score (ISS) of 22.5. Among them, 115 patients developed coagulopathy, 169 patients developed SIRS, 26 patients developed AKI, and 11 patients died during hospitalization. We found that Myoglobin (r = 0.225, P < 0.001), CK (r = 0.204, P < 0.001), LDH (r = 0.175, P = 0.002) were positively correlated with ISS. Myoglobin is an independent risk factor for coagulopathy (OR = 1.90, 95%CI: 1.45–2.49), SIRS (OR = 1.41, 95%CI: 1.10–1.79), and AKI (OR = 4.17, 95%CI: 2.19–7.95). CK is an independent risk factor for coagulopathy (OR = 1.30, 95%CI: 1.00-1.67), while LDH is an independent risk factor for SIRS (OR = 1.49, 95%CI: 1.17–1.89) and AKI (OR = 2.30, 95%CI: 1.43–3.69). Especially for AKI, Myoglobin had a good predictive effect (AUC = 0.804, 95%CI:0.716–0.891). The best cut-off value is when the Myoglobin value is 931.11 µg/L, at which point the sensitivity is 61.53% and the specificity is 87.41%. The admission muscle injury index can predict trauma complications such as AKI, early coagulation disease, and SIRS, especially AKI. Compared to CK and LDH, admission myoglobin can predict complications remarkably, even better than ISS, especially AKI. Routine testing of muscle injury indicators upon admission is meaningful and can help physicians identify and prevent the occurrence of complications.

There has been a slow uptake of wound bundles and prophylactic mesh augmentation (PMA) strategies despite evidence supporting their role in reducing burst abdomens and incisional hernias (IH). This study evaluates outcomes of resorbable synthetic prophylactic mesh augmentation in reducing these rates and assesses the complication profile in emergency abdominal surgery. A retrospective ethically approved observational study of all patients who underwent emergency open abdominal surgery using supplemental prophylactic onlay TIGR® Mesh at Letterkenny University Hospital between September 2017 and April 2024 was undertaken to assess safety, complication profiles and outcomes. Comprehensive wound bundles and subcutaneous space closure were used. Of the 49 patients included, the mean age was 64 years (± 16.4, 31–86), 33/49 (67%) were female, and the mean body mass index (BMI) was 27 (± 7.4,17.3–45). 20% of patients had previous abdominal surgery. 19/49 (38%) patients experienced postoperative complications, of these 8 (42%) were Clavien-Dindo Grade I-II, and 11 (58%) were Grade III-IV. There were 7 in-hospital post-operative deaths (Grade V). 8 patients had open abdomens. Thirteen surgical site occurrences (SSO) were identified in 9 (18%) patients. There were no burst abdomens. Four of the superficial SSIs responded to antibiotics while one required opening and wound NPWT. Three patients (6%) developed an incisional hernia, which was detected at a mean follow-up of 353 days. A comprehensive, evidence-based wound bundle using onlay PMA with a synthetic resorbable mesh, achieves efficacious, safe abdominal wall closure in high-risk, emergency laparotomy patients, including those who require delayed abdominal wall closure.

Mild acute biliary pancreatitis (MABP) presents significant clinical and economic challenges due to its potential for relapse. Current guidelines advocate for early cholecystectomy (EC) during the same hospital admission to prevent recurrent acute pancreatitis (RAP). Despite these recommendations, implementation in clinical practice varies, highlighting the need for reliable and accessible predictive tools. The MINERVA study aims to develop and validate a machine learning (ML) model to predict the risk of RAP (at 30, 60, 90 days, and at 1-year) in MABP patients, enhancing decision-making processes. The MINERVA study will be conducted across multiple academic and community hospitals in Italy. Adult patients with a clinical diagnosis of MABP, in accordance with the revised Atlanta Criteria, who have not undergone EC during index admission will be included. Exclusion criteria encompass non-biliary aetiology, severe pancreatitis, and the inability to provide informed consent. The study involves both retrospective data from the MANCTRA-1 study and prospective data collection. Data will be captured using REDCap. The ML model will utilise convolutional neural networks (CNN) for feature extraction and risk prediction. The model includes the following steps: the spatial transformation of variables using kernel Principal Component Analysis (kPCA), the creation of 2D images from transformed data, the application of convolutional filters, max-pooling, flattening, and final risk prediction via a fully connected layer. Performance metrics such as accuracy, precision, recall, and area under the ROC curve (AUC) will be used to evaluate the model. The MINERVA study aims to address the specific gap in predicting RAP risk in MABP patients by leveraging advanced ML techniques. By incorporating a wide range of clinical and demographic variables, the MINERVA score aims to provide a reliable, cost-effective, and accessible tool for healthcare professionals. The project emphasises the practical application of AI in clinical settings, potentially reducing the incidence of RAP and associated healthcare costs. ClinicalTrials.gov ID: NCT06124989.

The application of robot-assisted surgical technology in treating brainstem hemorrhage has garnered increasing attention. Treatments such as stereotactic hematoma aspiration and neuroendoscopic surgery are becoming more prevalent in China. The aim of this study is to provide a detailed comparative analysis of the clinical effects of robot-assisted puncture technology versus traditional conservative treatment, offering a scientific basis for optimizing treatment plans and improving patient outcomes. A retrospective observational study was conducted from January 2019 to December 2023 at a single neurosurgery center. A total of 138 patients with severe brainstem hemorrhage were included, with 103 in the conservative treatment group and 35 in the robot-assisted puncture group.ROSA robot-assisted brainstem hemorrhage drainage is a precise neurosurgical procedure involving pre-surgical evaluations and examinations, including cranial CT, to determine the hemorrhage’s location, extent, and severity. Baseline data was extracted from the hospital’s electronic medical record system, including demographics, medical history, and clinical characteristics. Statistical analysis was performed to compare outcomes between the two treatment groups. The baseline characteristics of the patients in both groups were similar, with no significant differences in age, gender, smoking history, alcohol consumption, or other relevant factors. The median stay time was longer in the robot-assisted group (21.0 days) compared to the conservative group (15.0 days), with a significant difference (p = 0.004). The median cost of hospitalization was also higher in the robot-assisted group (105231.0 yuan) compared to the conservative group (55221.5 yuan), with a significant difference (p < 0.001). The mortality rate of the robot assisted group was significantly lower than that of the conservative treatment group, and the difference was significant. Additionally, the robot-assisted group had a lower discharge hematoma volume and a trend towards better clinical outcomes, as measured by the Glasgow Coma Scale (GCS) and modified Rankin Scale (mRS) scores. The results suggest that robot-assisted puncture technology may offer improved clinical outcomes in patients with brainstem hemorrhage compared to traditional conservative treatment. The precision and accuracy of the ROSA robot may contribute to better hematoma drainage and reduced complications. While the cost of hospitalization was higher in the robot-assisted group, the potential for improved patient outcomes and reduced long-term healthcare costs should be considered when evaluating the cost-effectiveness of this treatment approach. Further research is needed to validate these findings in larger, multicenter studies and to explore the potential benefits of robot-assisted treatment in different subpopulations of patients with brainstem hemorrhage. This study provides preliminary evidence that robot-assisted puncture technology may offer

Statistical analysis was performed to compare outcomes between the two treatment groups. The baseline characteristics of the patients in both groups were similar, with no significant differences in age, gender, smoking history, alcohol consumption, or other relevant factors. The median stay time was longer in the robot-assisted group (21.0 days) compared to the conservative group (15.0 days), with a significant difference (p = 0.004). The median cost of hospitalization was also higher in the robot-assisted group (105231.0 yuan) compared to the conservative group (55221.5 yuan), with a significant difference (p < 0.001). The mortality rate of the robot assisted group was significantly lower than that of the conservative treatment group, and the difference was significant. Additionally, the robot-assisted group had a lower discharge hematoma volume and a trend towards better clinical outcomes, as measured by the Glasgow Coma Scale (GCS) and modified Rankin Scale (mRS) scores. The results suggest that robot-assisted puncture technology may offer improved clinical outcomes in patients with brainstem hemorrhage compared to traditional conservative treatment. The precision and accuracy of the ROSA robot may contribute to better hematoma drainage and reduced complications. While the cost of hospitalization was higher in the robot-assisted group, the potential for improved patient outcomes and reduced long-term healthcare costs should be considered when evaluating the cost-effectiveness of this treatment approach. Further research is needed to validate these findings in larger, multicenter studies and to explore the potential benefits of robot-assisted treatment in different subpopulations of patients with brainstem hemorrhage. This study provides preliminary evidence that robot-assisted puncture technology may offer","PeriodicalId":48867,"journal":{"name":"World Journal of Emergency Surgery","volume":"174 1","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143485884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the coronavirus disease (COVID-19) pandemic, there has been a surge in cases of acute cholecystitis. The ChoCO-W global prospective study reported a higher incidence of gangrenous cholecystitis and adverse outcomes in COVID-19 patients. Through this secondary analysis of the ChoCO-W study data, we aim to identify significant risk factors for mortality in patients with acute cholecystitis during the COVID-19 pandemic, emphasizing the role of COVID-19 infection in patient outcomes and treatment efficacy.” The ChoCO-W global prospective study reported data from 2546 patients collected at 218 centers from 42 countries admitted with acute cholecystitis during the COVID-19 pandemic, from October 1, 2020, to October 31, 2021. Sixty-four of them died. Nonparametric statistical univariate analysis was performed to compare patients who died and patients who survived. Significant factors were then entered into a logistic regression model to define factors predicting mortality. The significant independent factors that predicted death in the logistic regression model with were COVID-19 infection (p < 0.001), postoperative complications (p < 0.001), and type (open/laparoscopic) of surgical intervention (p = 0.003). The odds of death increased 5 times with the COVID-19 infection, 6 times in the presence of complications, and it was reduced by 86% with adequate source control. Survivors predominantly underwent urgent laparoscopic cholecystectomy (52.3% vs. 23.4%). COVID-19 was an independent risk factor for death in patients with acute cholecystitis. Early laparoscopic cholecystectomy has emerged as the cornerstone of treatment for hemodynamically stable patients.

Early treatment and prevention are the keys to reducing the mortality of VTE in patients with thoracic trauma. This study aimed to develop and validate an automatic prediction model based on machine learning for VTE risk screening in patients with thoracic trauma. In this national multicenter retrospective study, the clinical data of chest trauma patients hospitalized in 33 hospitals in China from October 2020 to September 2021 were collected for model training and testing. The data of patients with thoracic trauma at Shanghai Sixth People’s Hospital from October 2021 to September 2022 were included for further verification. The performance of the model was measured mainly by the area under the receiver operating characteristic curve (AUROC) and the mean accuracy (mAP), and the sensitivity, specificity, positive predictive value, and negative predictive value were also measured. A total of 3116 patients were included in the training and validation of the model. External validation was performed in 408 patients. The random forest (RF) model was selected as the final model, with an AUROC of 0·879 (95% CI 0·856–0·902) in the test dataset. In the external validation, the AUROC was 0.83 (95% CI 0.794–0.866), the specificity was 0.756 (95% CI 0.713–0.799), the sensitivity was 0.821 (95% CI 0.692–0.923), the negative predictive value was 0.976 (95% CI 0.958–0.993), and the positive likelihood ratio was 3.364. This model can be used to quickly screen for the risk of VTE in patients with thoracic trauma. More than 90% of unnecessary VTE tests can be avoided, which can help clinicians target interventions to high-risk groups and ensure resource optimization. Although further validation and improvement are needed, this study has considerable clinical value.
早期治疗和预防是降低胸外伤后静脉血栓栓塞死亡率的关键。本研究旨在开发并验证一种基于机器学习的VTE风险自动预测模型，用于胸部创伤患者的VTE风险筛查。在这项全国性多中心回顾性研究中，收集了2020年10月至2021年9月在中国33家医院住院的胸外伤患者的临床资料，进行模型训练和检验。纳入上海市第六人民医院2021年10月至2022年9月收治的胸外伤患者数据进行进一步验证。主要通过受试者工作特征曲线下面积（AUROC）和平均准确度（mAP）来衡量模型的性能，同时衡量模型的敏感性、特异性、阳性预测值和阴性预测值。共纳入3116例患者进行模型的训练和验证。在408例患者中进行了外部验证。随机森林（random forest， RF）模型作为最终模型，测试数据集的AUROC为0.879 （95% CI为0.856 - 0.902）。外部验证的AUROC为0.83 (95% CI 0.794-0.866)，特异性为0.756 (95% CI 0.713-0.799)，敏感性为0.821 (95% CI 0.692-0.923)，阴性预测值为0.976 (95% CI 0.958-0.993)，阳性似然比为3.364。该模型可用于快速筛选胸外伤患者静脉血栓栓塞的风险。可以避免90%以上不必要的静脉血栓栓塞检查，这可以帮助临床医生针对高危人群进行干预，并确保资源优化。虽然需要进一步的验证和改进，但本研究具有相当的临床价值。

Decision-making in emergency settings is inherently complex, requiring surgeons to rapidly evaluate various clinical, diagnostic, and environmental factors. The primary objective is to assess a patient’s risk for adverse outcomes while balancing diagnoses, management strategies, and available resources. Recently, indocyanine green (ICG) fluorescence imaging has emerged as a valuable tool to enhance surgical vision, demonstrating proven benefits in elective surgeries. This consensus paper provides evidence-based and expert opinion-based recommendations for the standardized use of ICG fluorescence imaging in emergency settings. Using the PICO framework, the consensus coordinator identified key research areas, topics, and questions regarding the implementation of ICG fluorescence-guided surgery in emergencies. A systematic literature review was conducted, and evidence was evaluated using the GRADE criteria. A panel of expert surgeons reviewed and refined statements and recommendations through a Delphi consensus process, culminating in final approval. ICG fluorescence imaging, including angiography and cholangiography, improves intraoperative decision-making in emergency surgeries, potentially reducing procedure duration, complications, and hospital stays. Optimal use requires careful consideration of dosage and timing due to limited tissue penetration (5–10 mm) and variable performance in patients with significant inflammation, scarring, or obesity. ICG is contraindicated in patients with known allergies to iodine or iodine-based contrast agents. Successful implementation depends on appropriate training, availability of equipment, and careful patient selection. Advanced technologies and intraoperative navigation techniques, such as ICG fluorescence-guided surgery, should be prioritized in emergency surgery to improve outcomes. This technology exemplifies precision surgery by enhancing minimally invasive approaches and providing superior real-time evaluation of bowel viability and biliary structures—areas traditionally reliant on the surgeon’s visual assessment. Its adoption in emergency settings requires proper training, equipment availability, and standardized protocols. Further research is needed to evaluate cost-effectiveness and expand its applications in urgent surgical procedures.

Clinical scoring algorithms are cost efficient in patients with suspicion of acute appendicitis. This is a systematic review and meta-analysis of the diagnostic properties of the Appendicitis Inflammatory Response (AIR) score compared with the Alvarado score. The PubMed, EMBASE, Web of Science and Google Scholar databases were searched for reports on the diagnostic properties of the AIR score from 2008 to July 18, 2024. A meta-analysis of the receiver operating characteristic (ROC) area and the sensitivity and specificity for all and advanced appendicitis patients was performed. Advanced appendicitis was defined as perforated or gangrenous appendicitis or appendicitis abscess or phlegmon or if described as complicated appendicitis. The risk of bias was estimated via the QUADAS-2 tool. The ROC areas of the AIR score and the Alvarado score were compared. A total of 26 reports with a total of 15.699 patients were included. The area under the ROC curve for the AIR score was 0.86 (95% CI 0.83–0.88) for all patients with appendicitis and 0.93 (CI 0.91–0.96) for those with advanced appendicitis, which was greater than the corresponding areas for the Alvarado score (0.79, CI 0.76; 0.81) and 0.88, CI 0.82; 0.95), respectively. At > 4 points, the sensitivity was 0.91 (CI 0.88; 0.94) for all patients with appendicitis and 0.95 (CI 0.94; 0.97) for those with advanced appendicitis. At > 3 points, the sensitivity was 0.95 (0.90; 0.97) for all patients with appendicitis and 0.99 (0.97; 0.99) for those with advanced appendicitis. At > 8 points, the specificity was 0.98 (0.97; 0.99) for all patients with appendicitis and 0.99 (0.97; 0.99) for those with advanced appendicitis. The included studies had a low risk for bias and low heterogeneity. The AIR score has a better diagnostic capacity than the Alvarado score does. The AIR score is a safe and efficient basis for risk-stratified management of patients suspected of having appendicitis.
