Background: Multi-detector contrast-enhanced abdominal computed tomography (CT) allows for the accurate detection and classification of traumatic splenic injuries, leading to improved patient management. Their effective use requires rapid study interpretation, which can be a challenge on busy emergency radiology services. A machine learning system has the potential to automate the process, potentially leading to a faster clinical response. This study aimed to create such a system. Method: Using the American Association for the Surgery of Trauma (AAST), spleen injuries were classified into 3 classes: normal, low-grade (AAST grade I-III) injuries, and high-grade (AAST grade IV and V) injuries. Employing a 2-stage machine learning strategy, spleens were initially segmented from input CT images and subsequently underwent classification via a 3D dense convolutional neural network (DenseNet). Results: This single-centre retrospective study involved trauma protocol CT scans performed between January 1, 2005, and July 31, 2021, totaling 608 scans with splenic injuries and 608 without. Five board-certified fellowship-trained abdominal radiologists utilizing the AAST injury scoring scale established ground truth labels. The model achieved AUC values of 0.84, 0.69, and 0.90 for normal, low-grade injuries, and high-grade splenic injuries, respectively. Conclusions: Our findings demonstrate the feasibility of automating spleen injury detection using our method with potential applications in improving patient care through radiologist worklist prioritization and injury stratification. Future endeavours should concentrate on further enhancing and optimizing our approach and testing its use in a real-world clinical environment. [ABSTRACT FROM AUTHOR]

Background Trauma is a significant cause of morbidity and mortality worldwide among children. Nonoperative management is the standard of care in hemodynamically stable children with blunt abdominal solid organ injury. Embolization is a potential pathway, which has shown increasing evidence for benefit in adult trauma patients. However, the data in children is limited. Materials and Methods A retrospective analysis of hospital data of all children (<18 years of age), presenting to a tertiary-care trauma center in India, with history of blunt trauma from January 2021 to June 2023, was performed. Preprocedural imaging, angiographic and embolization details, number of blood transfusions, and length of hospital stay were assessed. Results Two hundred and sixteen children (average age: 11.65 years) presented with a history of abdominal trauma during the study period. Eighty four children were FAST positive, out of whom, 67 patients had abdominal solid organ injury on computed tomography. Liver was the most commonly injured solid organ (n = 45), followed by the spleen and kidney. Ten children had solid abdominal organ arterial injuries for which eight children underwent embolization. The average length of hospital stay in embolization group (n = 8) was 4 days, as compared to 11 days in children undergoing operative management (n = 2). At 6 months follow-up, all children were asymptomatic. Conclusion Superselective embolization is a safe and feasible procedure in appropriately selected children with abdominal injury.

Background: Complications arising during non-operative management (NOM) of blunt hepatic and/or splenic trauma, particularly in cases of severe injury, are associated with significant morbidity and mortality. Abdominal computed tomography (CT) is the gold standard for the initial detection of complications during NOM. Although many institutions advocate routine in-hospital follow-up scans to improve success rates, others recommend a more selective approach. The use of follow-up CT remains a subject of ongoing debate, with no validated guidelines available regarding the timing, effectiveness, or intervals of follow-up imaging. Objective: We aimed to identify the clinical parameters for the early detection of complications in patients with blunt hepatic and/or splenic injury undergoing NOM. Materials and methods: This retrospective cohort study included patients with blunt hepatic and/or splenic trauma treated at Songklanagarind Hospital, a level 1 trauma center, from 2013 to 2022. We assessed all patients indicated for non-operative management and examined their clinical parameters and complications. Results: Of 542 patients with blunt hepatic and/or splenic injuries, 315 (58%) were managed non-operatively. High-grade hepatic injuries were significantly associated with complications, as determined through a multivariate logistic regression analysis after adjusting for factors such as contrast blush findings, age, sex, and injury severity score (ISS) (adjusted OR = 7.69, 95% CI 1.59–37.13; p = 0.011). Among the patients with complications (n = 27), 17 (63%) successfully underwent non-operative management. Notably, eight patients presented with clinical symptoms prior to the diagnosis of complications, while only two patients had no clinical symptoms before the diagnosis. Tachycardia, abdominal pain, decreased hematocrit levels, and fever were significant indicators of complications (p < 0.05). Conclusion: Routine CT to detect complications may not be necessary in patients with asymptomatic low-grade blunt hepatic injuries. By contrast, in those with isolated blunt hepatic injuries that are managed non-operatively, high-grade injuries, the presence of a contrast blush on initial imaging, and the patient's age may warrant consideration for routine follow-up CT scans. Clinical symptoms and laboratory observations during NOM, such as tachycardia, abdominal pain, decreased hematocrit levels, and fever, are significantly associated with complications. These symptoms necessitate further management, regardless of the initial injury severity, in patients with blunt hepatic and/or splenic injuries undergoing NOM. [ABSTRACT FROM AUTHOR]

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.

Solid organ injury (SOI) is common in children who experience abdominal trauma, and the management of such injuries has evolved significantly over the past several decades. In 2000, the American Pediatric Surgical Association (APSA) published the first societal guidelines for the management of blunt spleen and/or liver injury (BLSI), advocating for optimized resource utilization while maintaining patient safety. Nonoperative management (NOM) has become the mainstay of treatment for SOI, and since the publication of the APSA guidelines, numerous groups have evaluated how invasive procedures, hospitalization, and activity restrictions may be safely minimized in children with SOI. Here, we review the current evidence-based management guidelines in place for the treatment of injuries to the spleen, liver, kidney, and pancreas in children, including initial evaluation, inpatient management, and long-term care, as well as gaps that exist in the current literature that may be targeted for further optimization of protocols for pediatric SOI.

The liver, spleen, and kidneys are the commonest injured solid organs in blunt and penetrating trauma. The American Association for the Surgery of Trauma (AAST) Organ Injury Scale (OIS) is the most widely accepted system for categorizing traumatic injuries. Grading systems allow clear communication of findings between clinical teams and assign a measurable severity of injury, which directly correlates with morbidity and mortality. The 2018 revised AAST OIS emphasizes reliance on CT for accurate grading; in particular regarding vascular injuries. Dual-Energy CT (DECT) has emerged as a promising tool with multiple clinical applications already demonstrated. In this review article, we summarize the basic principles of CT attenuation to refresh the minds of our readers and we scrutinize DECT's technology as opposed to conventional Single-Energy CT (SECT). This is followed by outlining the benefits of various DECT postprocessing techniques, which authors of this article refer to as the 3Ms (Mapping of Iodine, Material decomposition, and Monoenergetic virtual imaging), in aiding radiologists to confidently assign an OIS as well as problem solve complex injury patterns. In addition, a thorough discussion of changes to the revised AAST OIS focusing on definitions of key terms used in reporting injuries is described. [ABSTRACT FROM AUTHOR]

Summary: Thrombolysis with prolonged cardiopulmonary resuscitation may be required for the successful resuscitation of patients presenting with massive pulmonary embolism leading to cardiac arrest. A rare, recognised complication of cardiopulmonary resuscitation is traumatic hepatic and splenic laceration. The incidence of complications is believed to be increased in those who receive automated mechanical cardiopulmonary resuscitation, compared to those who receive standard chest compressions. We present a case of a patient with massive pulmonary embolism leading to cardiac arrest which was successfully treated with thrombolysis and mechanical automated cardiopulmonary resuscitation. The patient suffered hepatic and splenic lacerations resulting in major haemorrhage. This required emergency resuscitation with blood products and splenic embolisation. This case highlights the importance of continual re‐assessment of patients, the early recognition of complications and an awareness of the potential complications of treatments we deliver.

Aim: To determine the association of successful and unsuccessful operative vaginal delivery attempts with risk of severe neonatal birth injury. Methods: We conducted a population‐based observational study of 1 080 503 births between 2006 and 2019 in Quebec, Canada. The main exposure was operative vaginal delivery with forceps or vacuum, elective or emergency cesarean with or without an operative vaginal attempt, and spontaneous delivery. The outcome was severe birth injury, including intracranial hemorrhage, brain and spinal damage, Erb's paralysis and other brachial plexus injuries, epicranial subaponeurotic hemorrhage, skull and long bone fractures, and liver, spleen, and other neonatal body injuries. We determined the association of delivery mode with risk of severe birth injury using adjusted risk ratios (RR) and 95% confidence intervals (CI). Results: A total of 8194 infants (0.8%) had severe birth injuries. Compared with spontaneous delivery, vacuum (RR 2.98, 95% CI 2.80–3.16) and forceps (RR 3.35, 95% CI 3.07–3.66) were both associated with risk of severe injury. Forceps was associated with intracranial hemorrhage (RR 16.4, 95% CI 10.1–26.6) and brain and spinal damage (RR 13.5, 95% CI 5.72–32.0), while vacuum was associated with epicranial subaponeurotic hemorrhage (RR 27.5, 95% CI 20.8–36.4) and skull fractures (RR 2.04, 95% CI 1.86–2.25). Emergency cesarean after an unsuccessful operative attempt was associated with intracranial and epicranial subaponeurotic hemorrhage, but elective and other emergency cesareans were not associated with severe injury. Conclusions: Operative vaginal delivery and unsuccessful operative attempts that result in an emergency cesarean are associated with elevated risks of severe birth injury. [ABSTRACT FROM AUTHOR]

Purpose: Retrospective review of splenic artery embolization (SAE) outcomes performed for blunt abdominal trauma. Materials and Methods: 11-year retrospective review at a large level-1 Canadian trauma centre. All patients who underwent SAE after blunt trauma were included. Technical success was defined as angiographic occlusion of the target vessel and clinical success was defined as successful non-operative management and splenic salvage on follow-up. Results: 138 patients were included of which 68.1% were male. The median age was 47 years (interquartile range (IQR) = 32.5 years). The most common mechanisms of injury were motor vehicle accidents (37.0%), mechanical falls (25.4%), and pedestrians hit by motor vehicles (10.9%). 70.3% of patients had American Association for the Surgery of Trauma (AAST) grade 4 injuries. Patients were treated with proximal SAE (n = 97), distal SAE (n = 23) or combined SAE (n = 18), and 68% were embolized with an Amplatzer plug. No significant differences were observed across all measures of hospitalization (Length of hospital stay: x2(2) =.358, P =.836; intensive care unit (ICU) stay: x2(2) =.390, P =.823; ICU stay post-procedure: x2(2) = 1.048, P =.592). Technical success and splenic salvage were achieved in 100% and 97.8% of patients, respectively. 7 patients (5%) had post-embolization complications and 7 patients (5%) died during hospital admission, but death was secondary to other injuries sustained in the trauma rather than complications related to splenic injury or its management. Conclusion: We report that SAE as an adjunct to non-operative management of blunt splenic trauma can be performed safely and effectively with a high rate of clinical success.

Background: There are no definitive recommendations guiding repeat imaging, or its timing, in patients with blunt splenic injury managed non-operatively. This study examines delayed complications and interventions in patients with blunt splenic injuries who undergo repeat imaging. Imaging was prompted either by a clinical change (CC) or non-clinical change (NCC) including institutional recommendations and individual physician practice patterns. Methods: A 3-year, retrospective, dual-institution study was conducted of adult patients with blunt splenic injuries. Patients who underwent repeat imaging were grouped based on the reason for scan: CC or NCC. The incidence of delayed complications and interventions was examined. Results: Of 235 patients, 105 (45%) underwent repeat imaging [CC n = 67 (64%), NCC n = 38 (36%)]. Median time to repeat imaging was shorter in the NCC group [CC = 96 (IQR 48–192) hours, NCC = 48 (IQR 36–68) hours, p =.0005]. Delayed complications were found in 28 (42%) CC patients versus 18 (47%) NCC patients (p =.683). Interventions for complications were performed in 6 (21%) CC versus 10 (56%) NCC (p =.027). Discussion: Nearly half of patients reimaged because of NCC were found to have complications, with more than half undergoing intervention. Complications were identified and treated earlier in the NCC group than the CC group. This suggests patients with blunt splenic injuries should undergo routine repeat imaging to allow for prompt identification and treatment of delayed complications. [ABSTRACT FROM AUTHOR]

BACKGROUND: Leaving an injured solid organ in situ allows preservation of structure function but invites complications from the damaged parenchyma, including pseudoaneurysms (PSAs). Empiric PSA screening after solid organ injury is not yet established, particularly following penetrating trauma. The study objective was definition of delayed CT angiography (dCTA) yield in triggering intervention for PSA after penetrating solid organ injury. METHODS: Penetrating trauma patients at our American College of Surgeons-verified level 1 center with American Association for the Surgery of Trauma grade ≥3 abdominal solid organ injury (liver, spleen, kidney) were retrospectively screened (January 2017 to October 2021). Exclusions were age <18 y, transfers, death within <48 h, and nephrectomy/splenectomy within <4 h. Primary outcome was intervention triggered by dCTA. Statistical testing with ANOVA/chisquare compared outcomes between screened vs unscreened patients. RESULTS: A total of 136 penetrating trauma patients met study criteria: 57 patients (42%) screened for PSA with dCTA and 79 (58%) unscreened. Liver injuries were most common (n = 41, 64% vs n = 55, 66%), followed by kidney (n = 21, 33% vs n = 23, 27%) and spleen (n = 2, 3% vs n = 6, 7%) (p = 0.48). Median American Association for the Surgery of Trauma grade of solid organ injury was 3 (3 to 4) across groups (p = 0.75). dCTA diagnosed 10 PSAs (18%) at a median of hospital day 5 (3 to 9). Among screened patients, dCTA triggered intervention in 17% of liver patients, 29% of kidney patients, and 0% of spleen-injured patients, for an overall yield of 23%. CONCLUSIONS: Half of eligible penetrating high-grade solid organ injuries were screened for PSA with dCTA. dCTA identified a significant number of PSAs and triggered intervention in 23% of screened patients. dCTA did not diagnose any PSAs after splenic injury, although sample size hinders interpretation. To avoid missing PSAs and incurring their risk of rupture, universal screening of high-grade penetrating solid organ injuries may be prudent. [ABSTRACT FROM AUTHOR]

Background: Non-operative management (NOM) has shown success in the management of cases of blunt abdominal trauma (BAT), especially in hemodynamically stable patients, even if there is a higher grade of injury. Objectives: The aim of this study was to determine the healing rate with NOM and associated risk factors of non-healing in patients with BAT. Methods: This prospective study was conducted on 20 hemodynamically stable patients of BAT who were treated in a tertiary care hospital by NOM. Clinical monitoring and biochemical investigations were done. The patients were followed-up for three months. The outcome measures were the average time of healing and complications. A p-value less than 0.05 was considered statistically significant. Results: The mean age of the patients was 24.5 years with 18 (90%) males and 2(10%) females. Nine patients (45%) had isolated liver injury, 8 (40%) had isolated splenic injury, 1 (5%) had isolated left renal injury, 1 (5%) had combined liver and splenic injury and 1 (5%) had combined liver and right renal injury. At 3 months of follow-up, 16 (80%) cases showed complete healing, 3(15%) showed incomplete healing and 1 (5%) patient with grade 4 splenic injury had failure of NOM. On performing univariate regression analysis, grade 3/4 was an independent risk factor of non-healing with an odds ratio of 5.667. Conclusion: In conclusion, NOM appears to be a safe and effective management protocol for patients with BAT, provided regular followups and monitoring are done. [ABSTRACT FROM AUTHOR]

Background: India is experiencing increasing road traffic accidents (RTA) amidst increasing motorization and infrastructure growth in recent years. Every day, nearly 400 road deaths occur on Indian roads and several thousands are hospitalized due to road crashes. WHO estimates the incidence of road deaths to be 16.6 per 100000 population in India1. With the aim of studying pattern and exploring various epidemiological characteristics of RTAs, this retrospective study of medico-legal autopsies was conducted. Aims & Objectives: 1 To study the pattern of thoraco-abdominal injuries (TAI) in fatal road traffic accidents in Kolar. 2. To describe demographic profile and create public awareness on road safety. Material & Methods: A retrospective autopsy based study of pattern of thoraco-abdominal injuries in victims of fatal road traffic accidents was conducted in Sri Devaraj Urs Medical College, Kolar (South India) from 1st January 2014 to 31st December 2014. A total of 192 RTA victims were referred for autopsy during the period of which 100 cases sustaining thoraco-abdominal injuries were studied. Results: A total of 192 medicolegal autopsies were conducted on victims of road traffic accidents (RTA) during the study period. Among them, 100 victims suffered thoraco-abdominal injuries, which accounted for 52.08% of the cases. The highest number of victims belonged to the age group of 20-40 years, accounting for 48% of the cases. In terms of gender distribution, males constituted 62.0% of the victims while females constituted 38.0%. The most common injuries were to the liver, accounting for 37.75% of the total injuries. Other frequently affected body parts included the spleen, lungs, thorax, abdomen, pelvis, and spine. Conclusion: The analyzed data provides clear evidence that road accidents are foreseeable and avoidable. To make substantial improvements in road safety throughout India, it is essential to establish a robust and effective national and state-level road safety authority, foster intersectoral coordination, and secure regular funding. Our aim in sharing this article is to increase public awareness of the significance of road traffic injuries from a public health perspective and to alleviate the weight of fatalities and injuries on our communities.

Background: Non-operative management (NOM) is the current standard of care of hemodynamically stable patients with traumatic blunt solid abdominal organ injuries. Guidelines do not define the optimal timing of initiation of venous thromboembolism (VTE) prophylaxis in this population, and fear of failure of NOM may lead to delayed initiation of prophylaxis specifically in patients with high-grade injuries. Methods: This was a single-center, retrospective study of patients with high-grade (AAST grades ≥3) blunt liver and splenic lacerations presenting to our level 1 trauma center between January 2010 and October 2017. Patients were divided into groups based on timing of low-molecular weight heparin (LMWH) initiation for VTE prophylaxis. The primary outcome was rate of failure of NOM, defined as the need for interventional radiology or surgical intervention for management of abdominal organ bleeding. Secondary outcomes included rates of VTE, lengths of ICU and hospital stay, and in-hospital mortality. Results: A total of 207 patients with high-grade blunt liver and splenic injuries undergoing an initial attempt at NOM were identified. The distribution of grades 3, 4, and 5 liver and splenic injuries were similar across all groups. Overall, 55.5% of patients received LMWH during their index admission. Early administration of LMWH was not associated with a statistically significant increased risk of failure of NOM (p = 0.054). Rates of VTE and in-hospital mortality were similar. Conclusions: Early initiation of VTE prophylaxis was not associated with an increased rate of failure of NOM in patients with high-grade blunt abdominal organ injuries in patients who survived 24 h post-admission and did not require massive transfusion; however, the study was likely underpowered to detect a difference among groups due to small sample size.

Introduction: Blunt diaphragm injury (BDI) is an uncommon, potentially fatal consequence of blunt torso injury. While associations between BDI and other factors such as mechanism of injury or other injuries have been described elsewhere, little recent research has been done in Australia into BDI. The aims of this study were to determine the incidence rate of BDI in our centre, identify how it was diagnosed, determine rates of missed injury and identify predictive factors for BDI. The hypothesis was that patients with BDI would significantly differ to those without BDI. Methods: All major trauma patients with blunt torso injuries at our Level 1 major trauma service from 2010 to 2018 were included. Data for patient demographics, other injuries, diagnosis and treatment of BDI were extracted. Patients with BDI were compared with patients without BDI in order to identify differences that could be used to predict BDI in future patients. Results: Of 5190 patients with a blunt torso injury, 51 (0.98%) had a BDI at a mean age of 53 ± 19.6 years, and median Injury Severity Score (ISS) of 27(IQR 21–38.5) compared with 5139 patients with a mean age of 48.2 ± 20.7 years and median ISS of 21.9(IQR 14–26) who did not have a BDI. The diagnosis of BDI was made at CT (n = 35), surgery (n = 14) or autopsy (n = 2). Blunt diaphragm injury was missed on index imaging for 11 of 43 patients (25.6%). On multivariate analysis, each point increase in ISS (OR 1.03, p = 0.02); rib fractures (OR 4.65, p = 0.004); splenic injury (OR 2.60, p = 0.004); and liver injury (OR 2.78, p = 0.003) were independently associated with BDI. Conclusion: Injury Severity Score, rib fractures and solid abdominal organ injury increase the likelihood of BDI. In patients with these injuries, BDI should be considered even in the presence of normal CT findings. [ABSTRACT FROM AUTHOR]

Purpose: Based on the hypothesis that systemic inflammation contributes to secondary injury after initial traumatic brain injury (TBI), this study aims to describe the effect of splenectomy on mortality in trauma patients with TBI and splenic injury. Methods: A retrospective cohort analysis of patients prospectively registered into the TraumaRegister DGU® (TR-DGU) with TBI (AISHead ≥ 3) combined with injury to the spleen (AISSpleen ≥ 1) was conducted. Multivariable logistic regression modeling was performed to adjust for confounding factors and to assess the independent effect of splenectomy on in-hospital mortality. Results: The cohort consisted of 1114 patients out of which 328 (29.4%) had undergone early splenectomy. Patients with splenectomy demonstrated a higher Injury Severity Score (median: 34 vs. 44, p < 0.001) and lower Glasgow Coma Scale (median: 9 vs. 7, p = 0.014) upon admission. Splenectomized patients were more frequently hypotensive upon admission (19.8% vs. 38.0%, p < 0.001) and in need for blood transfusion (30.3% vs. 61.0%, p < 0.001). The mortality was 20.7% in the splenectomy group and 10.3% in the remaining cohort. After adjustment for confounding factors, early splenectomy was not found to exert a significant effect on in-hospital mortality (OR 1.29 (0.67–2.50), p = 0.45). Conclusion: Trauma patients with TBI and spleen injury undergoing splenectomy demonstrate a more severe injury pattern, more compromised hemodynamic status and higher in-hospital mortality than patients without splenectomy. Adjustment for confounding factors reveals that the splenectomy procedure itself is not independently associated with survival. [ABSTRACT FROM AUTHOR]

Background:Successful non-operative management (NOM) of blunt splenic trauma is enhanced with splenic angioembolization (SAE). Patients may still require splenectomy post-SAE for splenic infarction/necrosis. Prior studies have used white blood cell count (WBC), platelet count (PLT), and PLT:WBC ratio after splenectomy to predict complications, but none have evaluated these findings prior to splenectomy in patients who have undergone SAE. Changes in these values may indicate clinically significant splenic infarction, facilitating management of these patients. Methods:Patients admitted to an American College of Surgeons verified level 1 trauma center from January 2007 to August 2017 who underwent SAE were identified. Patients with successful NOM after SAE (SAE/NOM) were compared with those requiring splenectomy (SAE/SPLEN). Data included demographics, splenic injury grade, Injury Severity Score (ISS), time to SAE and splenectomy, intensive care unit and hospital length of stay (LOS), and complete blood count. Lab values were analyzed immediately post-SAE (time 1) and day 5 post-SAE (or day of discharge) for SAE/NOM patients and day of SPLEN for SAE/SPLEN patients (time 2). Data were analyzed using Mann-Whitney U, χ2 tests, and receiver operating characteristic (ROC) curves with significance attributed to P

The Objective was to assess and improve the treatment results of victims with spleen injury in blunt abdominal trauma by using high-tech minimally invasive methods of diagnosis and treatment.Methods and materials. The article analyzed the results of treatment of 86 patients with isolated and combined blunt spleen injuries who received conventional surgery, and 52 similar patients who were treated in accordance with the new algorithm. This algorithm included conventional splenectomy for unstable hemodynamics and non-operative and minimally invasive management for stable hemodynamics after MSCT. In the absence of CT signs of ongoing bleeding, non-operative management was performed, if ongoing bleeding signs were detected, angiography with selective angioembolization was performed.Results. In both groups, most of the victims with blunt spleen injury were admitted to the trauma center after traffic accidents and catatraumas. There were no statistically significant differences in the injury severity (ISS, Tsibin scales), and the condition severity (VPH-SP). The tactics of non-operative and minimally invasive management was applied in 31 patients of the prospective group with stable hemodynamics. Non-operative management was performed on 16 patients of the prospective group. Four patients of this group underwent angiography and selective embolization of the branches of the splenic artery. In the retrospective group, there was a greater number of local complications compared to the prospective group (p=0.006). The decrease in the number of visceral and generalized complications was statistically insignificant (p>0.05). In the retrospective group, 21 victims died. Of these, 12 patients died from severe combined trauma and massive blood loss during the first 24 hours. In the prospective group, the total number of deaths was 10 patients. Of these, 6 died from polytrauma with acute massive blood loss, 1 – from severe traumatic brain injury, 1 – from PE, 2 – from sepsis. In the prospective group, among the patients with stable hemodynamics who had conservative treatment of abdominal trauma, 2 deaths were observed in the long-term period due to severe traumatic brain injury and PE.Conclusion. Organ-preserving management was carried out in 26 of 52 (50 %) patients, the number of performed diagnostic laparocenteses was reduced by 50.6 %, laparoscopies – by 16.5 %, laparotomies – by 60.7 %, the duration of inpatient treatment of surviving patients was more than for 7 days, mortality – by 5.2 %.

Despite significant interest in trauma to the spleen over the past 130 years, splenectomy remained the preferred approach to splenic injures in children till the late 1950s and even later in adults. With recognition of the immunologic importance of the spleen and improvements in diagnostic imaging and angioembolization, there are now four pathways for the child or adult admitted with a possible, likely, or diagnosed injury to the spleen. These include the following: (1) operation with splenectomy; (2) operation with splenorrhaphy or partial splenectomy; (3) nonoperative management (observation); and (4) nonoperative management with splenic arteriography and possible angioembolization. This review will focus on the latter two options. [ABSTRACT FROM AUTHOR]

Background: Angioembolization is an important adjunct in the non-operative management of adult trauma patients with splenic injury. Multiple studies have shown that angioembolization may increase the non-operative splenic salvage rate for patients with high-grade splenic injuries. We performed a systematic review and developed evidence-based recommendations regarding the need for post-splenectomy vaccinations after splenic embolization in trauma patients.Methods: A systematic review and meta-analysis of currently available evidence were performed utilizing the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology.Results: Nine studies were identified and analyzed. A total of 240 embolization patients were compared to 443 control patients who neither underwent splenectomy nor were embolized. There was no statistical difference between the splenic immune function of embolized and control patients. In addition, a total of 3974 splenectomy patients was compared with 686 embolization patients. Embolization patients had fewer infectious complications and a greater degree of preserved splenic immune function.Conclusion: In adult trauma patients who have undergone splenic angioembolization, we conditionally recommend against routine post-splenectomy vaccinations.Study Type: systematic review/meta-analysis Level of evidence: level III.

Introduction: Trauma nursing requires specialized knowledge and skills. This article describes the case of a patient who was involved in a motor vehicle accident and presented to the emergency department with hypovolemic shock secondary to a splenic laceration. In the hospital, the patient experienced prolonged hypotension. Clinical Findings: The patient sustained a variety of insults to the cardiovascular, respiratory, endocrine, and musculoskeletal systems. Microbiological data and laboratory test results did not reveal the defining characteristics of sepsis or systemic inflammatory response syndrome typical of trauma patients, making it challenging to identify the source of the sepsis. Diagnosis: The patient was diagnosed with nontraumatic cerebral septic emboli, a condition that is less common in trauma patients and more common in cases of endocarditis, septic thrombophlebitis, and central venous catheter infections. The condition has a 50% mortality rate if not detected promptly and appropriate treatment administered. Outcomes: The patient survived the 4-week hospitalization owing to timely management of his conditions by the health care team and their persistence in identifying the cause of his atypical sepsis. Conclusion: To provide adequate care to trauma patients, critical care nurses require specialized knowledge of this unique population. Trauma critical care nursing should involve hands-off communication, thoughtful review of laboratory test and imaging results, and engagement in interdisciplinary care rounds. [ABSTRACT FROM AUTHOR]

Introduction: The first trauma surgery unit in Malaysia was established in 2011. After 10 years, we examine our experience in the management, and outcomes of blunt liver, spleen, and kidney injuries.Methods: This is a cross-sectional study of patients with blunt liver, spleen, and kidney injuries in a level 1 trauma centre in Malaysia between January 2018 to June 2021. Patients' characteristics, new injury severity score, organ-specific AAST injury score, type of primary management (operative management [OM], non-operative management [NOM]), causes of failed NOM, management of failed NOM, and outcome of treatment were recorded and analysed.Results: Among 448 patients, 83.9% were male and in the working-age range of 15-64 years old (93.5%). Road traffic crashes made up 92.0% of blunt trauma resulting in 65.5% of isolated organ injuries and 34.5% combined injuries. An overwhelming 84.2% of the patients had major trauma (NISS>15). Three hundred and thirty-four patients (74.6%) underwent initial non-operative management. Patients in the OM group showed lower mean GCS scores (p = 0.022) and higher NISS scores (p < 0.001). High-grade liver and kidney injuries were mostly treated with NOM (p < 0.001). In contradistinction, patients with high-grade spleen injuries had more OM performed (p < 0.001). NOM had been successful in 325 patients (97.3%) with 9 failures. Underlying causes for NOM failure were hemodynamic instability due to secondary bleeding and infectious complications. Overall mortality was 11.2%, which was significantly higher in the OM group (23.7%) than in the NOM group (6.9%).Conclusion: This study represents one of the largest single centre experiences on the blunt liver, spleen, and kidney injuries in Malaysia and South-East Asia. With good selection and adequate resources, non-operative management of blunt liver, spleen, and kidney injuries is a safe and effective therapeutic approach with a high success rate of 97.3%, avoiding the morbidity of unnecessary laparotomies.

Purpose: Blunt trauma often results in splenic injuries, with non-operative management (NOM) being the preferred approach for stable patients. Following NOM, splenic vascular injuries, such as pseudoaneurysms, may arise, prompting radiological follow-up. However, a consensus on optimal radiological follow-up strategies is lacking. This systematic review evaluates existing evidence on radiological follow-up post-NOM for traumatic splenic injuries., Methods: Conducting a systematic review following updated PRISMA guidelines, we searched MEDLINE, Embase, The Cochrane Library, and trial registries from January 2010 to March 2023. Inclusion criteria covered studies on radiological follow-up for blunt splenic injuries., Results: Out of 5794 studies, 17 were included involving 3392 patients. Various radiological modalities were used, with computed tomography (CT) being the most common. Vascular injuries occurred in 4.5% of patients, with most pseudoaneurysms diagnosed on day 2-6 post-trauma, and leading to intervention in 60% of these cases. Thirteen studies recommended routine follow-up, with six favouring CT, and seven supporting radiation-free modalities. Four studies proposed follow-up based on clinical indications, initial findings, or symptoms. Recommendations for specific timing of radiological follow-up ranged from 48 h to seven days post-injury. Regarding AAST grading, nine studies recommended follow-up for injury grade III and higher., Conclusion: Limited high-quality evidence exists on radiological follow-up in isolated blunt splenic injuries, causing uncertainty in clinical practice. However, our review suggests a reasonable need for follow-up, with contrast-enhanced ultrasound emerging as a promising alternative to CT. Specific timing and criteria for follow-up remain unresolved, highlighting the need for high-quality prospective studies to address these knowledge gaps., (© 2024.

Background: Over recent decades, splenic angioembolization (SAE) as an adjunct to non-operative management (NOM) has emerged as a prominent intervention for patients with blunt splenic injuries (BSI). SAE improves patient outcomes, salvages the spleen, and averts complications associated with splenectomy. This systematic review aimed to evaluate the failure rate and complications related to SAE in patients with BSI., Methods: A systematic literature search (PubMed, SCOPUS, and Cochrane Library) focused on studies detailing splenic angioembolization in blunt trauma cases. Articles that fulfilled the predetermined inclusion criteria were included. This review examined the indications, outcomes, failure rate, and complications of SAE., Results: Among 599 identified articles, 33 met the inclusion criteria. These comprised 29 retrospective studies, three prospective studies, and one randomized control trial. The analysis encompassed 25,521 patients admitted with BSI and 3,835 patients who underwent SAE. The overall failure rate of SAE was 5.3 %. Major complications predominantly were rebleeding (4.8 %), infarction (4.6 %), and abscess formation (4 %). Minor complications were fever (18.4 %), pleural effusion (13.1 %), and coil migration (3.9 %). Other complications included splenic atrophy, splenic cyst, hematoma, and access site complications such as splenic/femoral dissection. Overall, post embolization mortality was 0.08 %., Conclusion: SAE is a valuable adjunct in managing BSI, with a low failure rate. However, this treatment modality is not without the risk of potentially serious complications., Competing Interests: Declaration of competing interest All authors have no conflict of interests or financial issues to declare., (Copyright © 2024 Elsevier Ltd.

Background: The Abbreviated Injury Scale (AIS) is widely used for body region-specific injury severity. The American Association for the Surgery of Trauma Organ Injury Scale (AAST-OIS) provides organ-specific injury severity but is not included in trauma databases. Previous researchers have used AIS as a surrogate for OIS. This study aims to assess AIS-abdomen concordance with AAST-OIS grade for liver and spleen injuries, hypothesizing concordance in terms of severity (grade of OIS and AIS) and patient outcomes., Study Design: This retrospective study (July 2020 to June 2022) was performed at 3 trauma centers. Adult trauma patients with AAST-OIS grade III to V liver and spleen injury were included. AAST-OIS grade for each organ was compared with AIS-abdomen by evaluating the percentage of AAST-OIS grade correlating with each AIS score as well as rates of operative intervention for these injuries. Analysis was performed with chi-square tests and univariate analysis., Results: Of 472 patients, 274 had liver injuries and 205 had spleen injuries grades III to V. AAST-OIS grade III to V liver injuries had concordances rates of 85.5%, 71%, and 90.9% with corresponding AIS 3 to 5 scores. AAST-OIS grade III to V spleen injuries had concordances rates of 89.7%, 87.8%, and 87.3%, respectively. There was a statistical lack of concordance for both liver and spleen injuries (both p < 0.001). Additionally, there were higher rates of operative intervention for AAST-OIS grade IV and V liver injuries and grade III and V spleen injuries vs corresponding AIS scores (p < 0.05)., Conclusions: AIS should not be used interchangeably with OIS due to lack of concordance. AAST-OIS should be included in trauma databases to facilitate improved organ injury research and quality improvement projects., (Copyright © 2024 by the American College of Surgeons.

Objectives: Nonoperative management (NOM) of blunt splenic injury (BSI) is well accepted in appropriate patients. Splenic artery embolization (SAE) in higher-grade injuries likely plays an important role in increasing the success of NOM. We previously implemented a protocol requiring referral of all BSI grades III-V undergoing NOM for SAE. It is unknown the risk of complications as well as longitudinal outcomes. We aimed to examine the splenic salvage rate and safety profile of the protocol. We hypothesized the splenic salvage rate would be high and complications would be low., Methods: A retrospective study was performed at our Level 1 trauma center over a 9-year period. Injury characteristics and outcomes in patients sustaining BSI grades III-V were collected. Outcomes were compared for NOM on protocol (SAE) and off protocol (no angiography or angiography but no embolization). Complications for angiographies were examined., Results: Between January 2010 and February 2019, 570 patients had grade III-V BSI. NOM was attempted in 359 (63 %) with overall salvage rate of 91 % (328). Of these, 305 were on protocol while 54 were off protocol (41 no angiography and 13 angiography but no SAE). During the study period, for every grade of injury a pattern was seen of a higher salvage rate in the on-protocol group when compared to the off-protocol group (Grade III, 97 %(181/187) vs. 89 %(32/36), Grade IV, 91 %(98/108) vs. 69 %(9/13) and Grade V, 80 %(8/10 vs. 0 %(0/5). The overall salvage rate was 94 %(287) on protocol vs. 76 %(41) off protocol (p < 0.001, Cochran-Mantel-Haenszel test). Complications occurred in only 8 of the 318 who underwent angiography (2 %). These included 5 access complications and 3 abscesses., Conclusion: The use of a protocol requiring routine splenic artery embolization for all high-grade spleen injuries slated for non-operative management is safe with a very low complication rate. NOM with splenic angioembolization failure rate is improved as compared to non-SAE patients' at all higher grades of injury. Thus, SAE for all hemodynamically stable patients of all high-grade types should be considered as a primary form of therapy for such injuries., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Introduction: Identifying patients who can be safely managed in lower-level trauma centers is critical to avoid overburdening level I centers. This study examines the transfer patterns and outcomes of blunt splenic injury (BSI) patients cared for at 2 regional level III trauma centers as compared to an associated level I center., Methods: A retrospective cohort study was conducted including all trauma patients with BSI admitted to 2 level III trauma centers (TC3) and a level I center (TC1) between 2012 and 2022. Patients were broken into 3 categories: TC1, TC3, and transfer patients (transferred from TC3 to TC1)., Results: A total of 1480 patients were admitted to TC1, 208 patients to TC3, and 128 were transferred. 22.7% of transfer patients were children. No difference in splenic injury grade was seen between patients managed at TC1 and TC3. Patients presenting to TC1 had more severe concomitant injuries. Patients underwent urgent splenectomy at similar rates at TC1 and TC3 (15.1 vs 18.7%, P = .1). Successful nonoperative management was achieved at similar rates (81.3 vs 75.5%, P = .1). When controlling for ISS and ED disposition, there was no significant difference in length of stay (LOS), ICU LOS, and inpatient mortality between TC1 and TC3., Conclusion: Level III centers effectively managed BSI achieving comparable outcomes to the level 1 center. Transfers commonly occurred in pediatric and multisystem trauma patients, though high-grade splenic injuries were not predictive of transfer. High-grade BSI can be safely managed at level III centers without need for transfer., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: John Green: Zimmer, Atricure, Intuitive.

Background: Our institution updated blunt liver and spleen injury (BLSI) protocols in 2019 in adherence to updated American Pediatric Surgery Association recommendations. This retrospective study compares resource utilization for pediatric BLSI patients treated under old and updated guidelines., Methods: Blunt liver and spleen injury patients without severe non-abdomen injuries younger than 18 years treated with prior (April 2015 to June 2019) and updated (June 2019 to December 2022) guidelines were retrospectively reviewed and compared. Each patient received an adjusted Injury Severity Score (ISS) to control for non-BLSI injuries. Multivariate analysis examined protocol group differences while controlling for adjusted ISS and BLSI grades. Primary outcomes were intensive care unit (ICU) length of stay (LOS), hospital LOS (analyzed using Cox regression), and patient costs (linear regression). Secondary outcomes include readmission in 2 weeks and death rates (logistic regression)., Results: A total of 176 and 170 BLSI patients were treated with old and updated protocols, respectively. Patient demographics, average BLSI grade, and adjusted ISS were similar in both groups. Patients treated with old protocols indicate decreased hazard, showing significantly more days before ICU discharge (coefficient, -0.3868; p < 0.0009) and hospital discharge (coefficient, -0.5507; p < 0.0001). Patient costs (coefficient, 0.0921; p = 0.1874) trend toward being lower in the new protocol. Readmission rates were significantly higher in the new protocol (coefficient, -1.1731; p = 0.0465), and death rates (coefficient, 0.0519; p = 0.9710) were comparable., Conclusions: Blunt liver and spleen injury patients treated under new American Pediatric Surgery Association guidelines compared with old guidelines had significant decreases in ICU and hospital LOS, a decreasing trend in costs, and comparable death rates but higher readmission rates. Future studies with larger sample sizes and detailed cost analysis would explore whether updated guidelines reduce patient costs and help elucidate the veracity or potential cause of the increased readmission rates., Level of Evidence: Therapeutic/Care Management; Level III., (Copyright © 2024 Wolters Kluwer Health, Inc.

Purpose: The aim of this study was to evaluate the effectiveness of management strategies for blunt splenic injuries in adult patients., Methods: Patients 18 years and older with blunt splenic injuries registered via the Trauma Quality Improvement Program (2013-2019) were identified. Management strategies initiated within 24 hours of hospital presentation were classified as watchful waiting, embolization, surgery, or combination therapy. Patients were stratified by injury grade. Linear models estimated each strategy's effect on hospital length of stay (LOS), intensive care unit (ICU) LOS, and mortality., Results: Of 81,033 included patients, 86.3%, 10.9%, 2.5%, and 0.3% of patients received watchful waiting, surgery, embolization, and combination therapy, respectively. Among patients with low-grade injuries and compared with surgery, embolization was associated with shorter hospital LOS (9.4 days, Q < .001, Cohen's d = .30) and ICU LOS (5.0 days, Q < .001, Cohen's d = .44). Among patients with high-grade injuries and compared with surgery, embolization was associated with shorter hospital LOS (8.7 days, Q < .001, Cohen's d = .12) and ICU LOS (4.5 days, Q < .001, Cohen's d = .23). Among patients with low- and high-grade injuries, the odds ratios for in-hospital mortality associated with surgery compared with embolization were 4.02 (Q < .001) and 4.38 (Q < .001), respectively., Conclusions: Among patients presenting with blunt splenic injuries and compared with surgery, embolization was associated with shorter hospital LOS, shorter ICU LOS, and lower risk for mortality., (Copyright © 2024 American College of Radiology.

A 22-year-old woman jumped from the 4th floor of her apartment in an attempt to commit suicide. Whole-body computed tomography showed multiple injuries, including right acute subdural hematoma, left hemopneumothorax, several fractures, intraperitoneal hemorrhage, and spleen injury. Her consciousness deteriorated rapidly, and her right pupil was dilated. Furthermore, she had unstable vital signs including blood pressure of approximately 70/40 mmHg, pulse about 150/minute, respiratory rate 25/minute, and percutaneous oxygen saturation of 90% on 10 L oxygen. Intratracheal intubation and insertion of a thoracostomy tube were performed in the emergency room. Due to concomitant brain herniation and hemorrhagic shock, simultaneous decompressive craniectomy for acute subdural hematoma and transarterial embolization of intraperitoneal injured arteries were performed in our hybrid operating room. Despite rapid blood transfusions, the blood pressure did not increase. After starting embolization of the injured arteries of the spleen, the blood pressure increased, thereby making it possible to remove the acute subdural hematoma, and hemostasis was then achieved. Four hours later, the acute subdural hematoma and intracranial pressure increased again, and re-operation was performed in the normal operating room. Cranioplasty and clavicular fracture reduction were performed 14 days later. She recovered enough to talk and walk, and her consciousness stabilized. Interviews with her and her family by a psychiatrist determined that abnormal behaviors had first appeared 2 months earlier. She was diagnosed with acute and transient psychotic disorders, and treatment was started. The patient was discharged home 1 month later with mild disability of her higher-order brain function.

Purpose: The need to prevent venous thromboembolism (VTE) following blunt solid organ injury must be balanced against the concern for exacerbation of hemorrhage. The optimal timing for initiation of VTE chemoprophylaxis is not known. The objective was to determine the safety and efficacy of early (≤ 48 h) VTE chemoprophylaxis initiation following blunt solid organ injury. Methods: An electronic search was performed of medical libraries for English language studies on timing of VTE chemoprophylaxis initiation following blunt solid organ injury published from inception to April 2020. Included studies compared early (≤ 48 h) versus late (> 48 h) initiation of VTE chemoprophylaxis in adults with blunt splenic, liver, and/or kidney injury. Estimates were pooled using random-effects meta-analysis. Odds ratios were utilized to quantify differences in failure of nonoperative management, need for blood transfusion and rates of VTE. Results: The search identified 2,111 studies. Of these, ten studies comprising 14,675 patients were included. All studies were non-randomized and only one was prospective. The overall odds of failure of nonoperative management were no different between early and late groups, OR 1.09 (95%CI 0.92–1.29). Similarly, there was no difference in the need for blood transfusion either during overall hospital stay, OR 0.91 (95%CI 0.70–1.18), or post prophylaxis initiation, OR 1.23 (95%CI 0.55–2.73). There were significantly lower odds of VTE when patients received early VTE chemoprophylaxis, OR 0.51 (95%CI 0.33–0.81). Conclusions: Patients undergoing nonoperative management for blunt solid organ injury can be safely and effectively prescribed early VTE chemoprophylaxis. This results in significantly lower VTE rates without demonstrable harm. [ABSTRACT FROM AUTHOR]

Background: Blunt abdominal solid organ injury is common and is often managed nonoperatively. Clinicians must balance risk of both hemorrhage and thrombosis. The optimal timing of pharmacologic venous thromboembolism prophylaxis (VTEp) initiation in this population is unclear. The objective was to evaluate early (< 48 h) compared to late initiation of VTEp in adult trauma patients with blunt abdominal solid organ injury managed nonoperatively. Methods: Embase, MEDLINE, and the Cochrane Central Register of Controlled Trials were searched from inception to March 2021. Studies comparing timeframes of VTEp initiation were considered. The primary outcome was failure of nonoperative management (NOM) after VTEp initiation. Secondary outcomes included risk of transfusion, other bleeding complications, risk of deep vein thrombosis (DVT) and pulmonary embolism, and mortality. Results: Ten cohort studies met inclusion criteria, with a total of 4642 patients. Meta-analysis revealed a statistically significant increase in the risk of failure of NOM among patients receiving early VTEp (OR 1.76, 95% CI 1.01–3.05, p = 0.05). There was no significant difference in risk of transfusion. Odds of DVT were significantly lower in the early group (OR 0.36, 95% CI 0.22–0.59, p < 0.0001). There was no difference in mortality (OR 1.50, 95% CI 0.82–2.75, p = 0.19). All studies were at serious risk of bias due to confounding. Conclusions: Initiation of VTEp earlier than 48 h following hospitalization is associated with an increased risk of failure of NOM but a decreased risk of DVT. Absolute failure rates of NOM are low. Initiation of VTEp at 48 h may balance the risks of bleeding and VTE. [ABSTRACT FROM AUTHOR]

Background: The Eastern Association for the Surgery of Trauma (EAST) states there is not enough evidence to recommend a particular frequency of measuring Hgb values for non-operative management (NOM) of blunt splenic injury (BSI). This study was performed to compare the utility of serial Hgb (SHgb) to daily Hgb (DHgb) in this population.Methods: We conducted a retrospective chart review of patients with BSI between 2013 and 2019. Demographics, comorbidities, lab values, clinical decisions, and outcomes were gathered through a trauma database.Results: A total of 562 patients arrive in the trauma bay with BSI. In the NOM group, 297 were successful and 37 failed NOM. Of those that failed NOM, 8 (21.6%) changed to OM due to a drop in Hgb. 5 (62.5%) were hypotensive first, 2 (25%) were no longer receiving SHgb, and 1 (12.5%) had a repeat CT scan and was embolized. DHgb patients were not significantly different from SHgb patients in injury severity, length of stay, the largest drop in Hgb, and incidence of failing NOM. Patients taking aspirin were more likely to fall below 7 g/dl at 48 and 72 hours into admission.Conclusions: These results suggest that that trending SHgb may not influence clinical decision-making in NOM of BSI. Besides taking aspirin, risk factors for who would benefit from SHgb were not identified. Patients who received DHgb had similar injuries and outcomes than patients who received SHgb. Prospective studies are needed to evaluate the clinical utility of SHgb compared to DHgb. [ABSTRACT FROM AUTHOR]

Remote ischemic conditioning includes the transfer of information via humoral mediators and/or neurogenic pathways from the initial remote organ exposed to the ischemia to the target organ to be protected. The postulated mechanisms of protection in the target organ involve mitochondrial adaptation to metabolic stress, redox regulation, and downregulation of many key steps leading to cell death. As possible protective mechanisms of remote ischemic conditioning and sepsis pathogenesis have so many common components, in this study, we aimed to investigate the effect of remote ischemic conditioning on survival and organ injury in cecal ligation and perforation induced (CLP) sepsis in mice. After ethical committee approval, ninety Swiss albino mice were divided into 10 groups: control group, control + ischemia group, sham group, sham + ischemia group, sham + 5h ischemia group, sham + 20h ischemia group, CLP group, CLP + ischemia group, CLP + 5h ischemia group, and CLP + 20h ischemia group. In the ischemia groups, for RIC, right hind leg was subjected to 6 cycles of 5-min ischemia and 5-min reperfusion using a surgical clamp. Antibiotics, analgesics, and fluid replacement were applied for 3 days in all groups. The organ damages were scored under light microscopy. Lung injury-related histologically findings were more prominent in CLP + 20h ischemia group than CLP, CLP + ischemia, and CLP + 5h ischemia groups. Spleen injury scores were found higher in CLP + 5h ischemia and CLP + 20h ischemia group than CLP group. Parenchymal cardiac congestion score was higher in CLP + 20h ischemia group than CLP and CLP + 5h ischemia group. The heart necrosis score was highest in CLP + 20h ischemia group. Total organ injury and every single organ injury scores were also highest in the CLP+20h ischemia group. We could not demonstrate any protective effect of remote ischemic conditioning on septic organ injury neither at early nor at late phases of sepsis. In fact, remote ischemic conditioning increased organ injury especially when applied later in cecal ligation and perforation induced sepsis in mice. [ABSTRACT FROM AUTHOR]

Background: Splenorrhaphy was once used to achieve splenic preservation in up to 40% of splenic injuries. With increasing use of nonoperative management and angioembolization, operative therapy is less common and splenic injuries treated operatively are usually high grade. Patients are often unstable, making splenic salvage unwise. Modern surgeons may no longer possess the knowledge to perform splenorrhaphy.Methods: The records of adult trauma patients with splenic injuries from September 2014 to November 2018 at an urban level I trauma center were reviewed retrospectively. Data including American Association for the Surgery of Trauma splenic organ injury scale, type of intervention, splenorrhaphy technique, and need for delayed splenectomy were collected. This contemporary cohort (CC) was compared to a historical cohort (HC) of splenic injuries at a single center from 1980 to 1989 (Ann Surg 1990; 211: 369).Results: From 2014 to 2018, 717 adult patients had splenic injuries. Initial management included 157 (21.9%) emergent splenectomy, 158 (22.0%) angiogram ± embolization, 371 (51.7%) observation, and only 10 (1.4%) splenorrhaphy. The HC included a total of 553 splenic injuries, of which 313 (56.6%) underwent splenectomy, while splenorrhaphy was performed in 240 (43.4%). Those who underwent splenorrhaphy in each cohort (CC vs HC) were compared.Conclusion: The success rate of splenorrhaphy has not changed. However, splenorrhaphy now involves only electrocautery with topical hemostatic agents and is used primarily in low-grade injuries. Suture repair and partial splenectomy seem to be "lost arts" in modern trauma care. [ABSTRACT FROM AUTHOR]

Purpose: First time analysis of the epidemiology, management and outcomes of patients with splenic injuries in Switzerland. This study aims to assess the effect of hospital treatment volume on successful non-operative management (NOM) in splenic injuries. Methods: A multicentric registry-based study including all patients with splenic injuries entered into the Swiss Trauma Registry from 2015 to 2018 was conducted. Patients were stratified according to the hospitals treatment volume of splenic injuries. Primary outcome was the rate of successful NOM. Results: During the 4-year study period, 652 patients with splenic injury were included in the study. Median age of the study population was 42 (IQR 27–59) years, and median ISS was 26 (20–34). The overall rate of successful NOM was 86.5%. Median HLOS was 13 (8–21) days. In-hospital mortality was 7.2% (n = 47). The mean number of patients with splenic injuries per center and year was 14. Five out of 12 Level I trauma centers treating more patients than the mean (≥ 15/year) were defined as high-volume centers. Multivariable analysis adjusting for differences in baseline and injury characteristics revealed treatment in a high-volume center as an independent predictor for successful NOM (OR 2.15, 95% CI 1.28–3.60, p = 0.004) and shorter HLOS (RC − 2.39, 95% CI − 4.91/− 0.48, p = 0.017), however, not for reduced in-hospital mortality (OR 0.92, 95% CI 0.39–2.18, p = 0.845). Conclusion: Higher hospital treatment volume was associated with a higher rate of NOM and shorter HLOS, but not lower mortality. These results constitute the basis for further quality improvement in the care of splenic injury patients within the trauma system in Switzerland. [ABSTRACT FROM AUTHOR]

This is the first known case report of severe intrauterine adhesion (IUA) following a life‐threatening event caused by an Epstein–Barr virus‐associated atraumatic spleen laceration. A 22‐year‐old nulligravid female suffered from infectious mononucleosis for approximately 1 month. Sudden severe hypovolemic shock with massive hemoperitoneum appeared and hemostasis was completely achieved by a splenectomy for an atraumatic spleen laceration, although that was followed by multiorgan failure and abdominal compartment syndrome. Complete recovery without any neurological sequelae was achieved by intensive treatment. A postoperative pathological evaluation revealed Epstein–Barr virus‐associated splenomegaly. The patient was referred to our department because of secondary amenorrhea for approximately 5 months since the last menstruation, which occurred just prior to the event. Laboratory blood test results demonstrated normal thyroid and ovarian functions. Hysterofiberscopy revealed complete obstruction at the end of the cervical canal, indicating secondary uterine amenorrhea caused by severe IUA. Hysteroscopic adhesiolysis with a rigid hysteroscope reached the opening of the uterine cavity and menstruation was restored. [ABSTRACT FROM AUTHOR]

Background: For patients sustaining major trauma, preinjury warfarin use may make adequate haemostasis difficult. This study aimed to determine whether preinjury warfarin would result in more haemostatic interventions (transarterial embolization [TAE] or surgeries) and a higher failure rate of nonoperative management for blunt hepatic, splenic or renal injuries.Methods: This was a retrospective cohort study from the Taiwan National Health Insurance Research Database (NHIRD) from 2003 to 2015. Patients with hepatic, splenic or renal injuries were identified. The primary outcome measurement was the need for invasive procedures to stop bleeding. One-to-two propensity score matching (PSM) was used to minimize selection bias.Results: A total of 37,837 patients were enrolled in the study, and 156 (0.41%) had preinjury warfarin use. With proper 1:2 PSM, patients who received warfarin preinjury were found to require more haemostatic interventions (39.9% vs. 29.1%, p=0.016). The differences between the two study groups were that patients with preinjury warfarin required more TAE than the controls (16.3% vs 8.2%, p = 0.009). No significant increases were found in the need for surgeries (exploratory laparotomy (5.2% vs 3.6%, p = 0.380), hepatorrhaphy (9.2% vs 7.2%, p = 0.447), splenectomy (13.1% vs 13.7%, p = 0.846) or nephrectomy (2.0% vs 0.7%, p = 0.229)). Seven out of 25 patients (28.0%) in the warfarin group required further operations after TAE, which was not significantly different from that in the nonwarfarin group (four out of 25 patients, 16.0%, p = 0.306) CONCLUSION: Preinjury warfarin increases the need for TAE but not surgeries. With proper haemostasis with TAE and resuscitation, nonoperative management can still be applied to patients with preinjury warfarin sustaining blunt hepatic, splenic or renal injuries. Patients with preinjury warfarin had a higher risk for surgery after TAE. [ABSTRACT FROM AUTHOR]

The spleen is the most commonly injured solid organ following blunt abdominal trauma. Over recent decades, splenic artery embolization (SAE) has become the mainstay treatment for haemodynamically stable patients with high-grade blunt splenic trauma, with splenectomy the mainstay of treatment for unstable patients. Splenic function is complex but the spleen has an important role in immune function, particularly in protection against encapsulated bacteria. Established evidence suggests that following splenectomy immune function is impaired resulting in increased susceptibility to overwhelming post-splenectomy infection, however, immune function may be preserved following SAE. This review will discuss the current state of the literature on immune function following different treatments of blunt splenic injury, and the controversies surrounding what constitutes a quantitative test of splenic immune function.

Spleen injuries are among the most frequent trauma-related injuries. The approach for diagnosis and management of Blunt Splenic Injury (BSI) has been considerably shifted towards Non-Operative Management (NOM) in the last few decades. NOM of blunt splenic injuries includes Splenic Angio-Embolization (SAE). Aim of this study was to analyze Pisa Level 1 trauma center (Italy) last 10-years-experience in the management of Blunt Splenic Trauma (BST), and more specifically to evaluate NOM rate and failure. Retrospective analysis of all patients admitted with blunt splenic trauma was done. They were divided into two groups according to the treatment: hemodynamically unstable patients treated operatively (OM group) and patients underwent a non-operative management (NOM group). The CT scan performed in all NOM group patients. Univariate analysis was performed to identify differences between the two groups. Multivariate analysis adjusting for factors with a p value < 0.05 or with clinical relevance was used to identify possible risk factors for NOM failure. 193 consecutive patients with blunt splenic trauma were admitted. Emergency splenectomies were performed in 53 patients (OM group); 140 were managed non-operatively with or without SAE (NOM group). NOM rate in high grade injuries is 57%. Overall NOM failure rate is 9%, and success rate in high grade splenic injuries is 48%; multivariate analysis showed AAST score ≥3 as a risk factor for NOM failure. Non-operative management currently represents the gold standard management for hemodynamically stable patient with blunt splenic trauma even in high grade splenic injuries. AAST ≥3 spleen lesion is a failure risk factor but not a contraindication to for non-operative management. [ABSTRACT FROM AUTHOR]

Teaching Point: Splenic injury is an uncommon complication after endoscopic retrograde cholangiopancreatography (ERCP), requiring a high degree of suspicion in a patient who develops abdominal pain and/or hypotension after ERCP; in the appropriately selected patient splenic angioembolization can be the first-line treatment option.

Globally, the trend of using food additives and eating ready-made fast food has led to a deleterious impact on immune organs. Monosodium glutamate (MSG), as a food additive in a high-lipid diet (HLD), acts as a silent killer of immune cells. Hence, the present study aimed to evaluate the role of MSG in HLD on spleen injury in rats. Results showed that a 2.52-fold and 1.91-fold increase in spleen index in MSG and MSG + HLD group indicates splenomegaly, whereas a 1.36-fold and 1.29-fold increase in pro-inflammatory cytokines in MSG and MSG + HLD-fed rats, respectively, promote the inflammatory response. Additionally, MSG and MSG + HLD induce oxidative stress by 1.81-fold and 1.1-fold increased generation of reactive oxygen species (ROS) in macrophage population, and 1.38-fold and 1.36-fold increased generation of ROS in lymphocytes population, respectively. Furthermore, mitochondrial membrane potential was significantly reduced by 1.43-fold and 1.18-fold in MSG and MSG + HLD groups. Therefore, the current study argues that MSG has more detrimental effects on the spleen than MSG + HLD due to the presence of antioxidants in HLD, which suppresses the deleterious impact of MSG. Hence, it can be inferred that MSG induces spleen injury via targeting redox-guided cellular signaling with inflammatory response, leading to severe immune system anomalies. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the effectiveness of routine repeat computed tomography (CT) for nonoperative management (NOM) of adults with blunt liver and/or spleen injury. Methods: We conducted a systematic review of randomized and non-randomized controlled trials (RCTs), quasi-experimental and observational studies of repeat CT in adult patients with blunt abdominal injury. We searched Medline, Embase, Web of Science, and Cochrane Central from their inception to October 2020 using Cochrane guidelines. Primary outcomes were change in clinical management (e.g., emergency surgery, embolization, blood transfusion, clinical surveillance), mortality, and complications. Secondary outcomes were hospital readmission and length of stay. Results: Search results yielded 1611 studies of which 28 studies including 2646 patients met our inclusion criteria. The majority reported on liver (n = 9) or spleen injury (n = 16) or both (n = 3). No RCTs were identified. Meta-analyses were not possible because no study performed direct comparisons of study outcomes across intervention groups. Only seven of the twenty-eight studies reported whether repeat CT was routine or prompted by clinical indication. In these 7 studies, among the 254 repeat CT performed, 188 (74%) were routine and 8 (4%) of these led to a change in clinical management. Of the 66 (26%) repeated CT prompted by clinical indication, 31 (47%) led to a change in management. We found no data allowing comparison of any other outcomes across intervention groups. Conclusion: Routine repeat CT without clinical indication is not useful in the management of patients with liver and/or spleen injury. However, effect estimates were imprecise and included studies were of low methodological quality. Given the risks of unnecessary radiation and costs associated with repeat CT, future research should aim to estimate the frequency of such practices and assess practice variation. Level of evidence: Systematic reviews and meta-analyses, Level II. [ABSTRACT FROM AUTHOR]

Background: Non-operative management is the standard of care for pediatric blunt splenic injury. The American Pediatric Surgical Association recommends intensive care unit monitoring only for grade IV/V blunt splenic injury; however, variation remains regarding this practice. We hypothesized that pediatric trauma patients with near-isolated grade III blunt splenic injuries admitted to a non-intensive care unit setting would have similar outcomes to those admitted to the intensive care unit., Methods: The 2017 to 2019 Trauma Quality Improvement Program database was queried for blunt pediatric trauma patients (≤16 years) with near-isolated grade III blunt splenic injuries. Patients with systolic blood pressure <90 mmHg or heart rate >90 were excluded. Pediatric trauma patients admitted to the intensive care unit were compared to non-intensive care unit admissions. The primary outcome was splenectomy. Bivariate analyses were performed., Results: Of 461 pediatric trauma patients with near-isolated grade III blunt splenic injuries, 186 (40.3%) were admitted to the intensive care unit. Intensive care unit patients were older than their non-intensive care unit counterparts (15 vs 14 years, P = .03). Intensive care unit and non-intensive care unit patients had a similar rate of splenectomy (0.5% vs 0.7%, P = .80) and time to surgery (19.7 vs 19.8 hours, P = .98). Patients admitted to the intensive care unit had a longer length of stay (4 vs 3 days, P < .001). There were no significant complications or deaths in either group., Conclusion: This national analysis demonstrated that hemodynamically stable pediatric trauma patients with near-isolated grade III blunt splenic injuries admitted to the floor or intensive care unit had a similar rate of splenectomy without complications or deaths. This aligns with American Pediatric Surgical Association recommendations that pediatric trauma patients with grade III blunt splenic injuries be managed in non-intensive care unit settings. Widespread adoption is warranted and should lead to decreased healthcare expenditures., (Copyright © 2024 Elsevier Inc. All rights reserved.)
