Is it possible to predict mortality in patients with high-grade blunt liver injury? A single trauma center study. ULUS TRAVMA ACIL CER 2024; 30:276-284. [PMID: 38634851 PMCID: PMC11065970 DOI: 10.14744/tjtes.2024.60646] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2024] [Revised: 03/24/2024] [Accepted: 04/03/2024] [Indexed: 04/19/2024]
Abstract
BACKGROUND Blunt abdominal trauma constitutes a significant portion of trauma cases and is often associated with liver injury. Given that high-grade liver injuries remain life-threatening, identifying patients who will likely require more vigilant attention and care is crucial. This study aims to determine the parameters that increase mortality in patients with high-grade liver trauma. METHODS This study enrolled 38 patients with Grade III or higher liver injuries, treated by the general surgery department between 2008 and 2023. Eleven patients who died were categorized into Group 1, and 27 survivors were placed in Group 2. We evaluated their respective mechanisms of injury, imaging results, Glasgow Coma Scale scores, Base Excess, Lactate levels, pH, and Injury Severity Score findings. Receiver Operating Characteristics (ROC) analysis was performed for parameters with significant differences, and certain cutoff values were determined. RESULTS The grade of liver injury and additional abdominal organ injuries were significantly higher in Group 1 (p<0.05). The difference in extra-abdominal injury sites was statistically insignificant between the groups (p>0.05). Erythrocyte suspension requirements were significantly higher in Group 1 (p<0.05). Average lactate and base deficit values were also significantly higher in Group 1 (p<0.05), while leukocyte counts were significantly lower in Group 1 (p<0.05). CONCLUSION Base deficit, hemoglobin (Hb), lactate levels, injury severity, liver injury grade, accompanying abdominal injuries at admission, and erythrocyte suspension demands were found to be associated with increased mortality rates. Certain cutoff values for the aforementioned parameters could be established. However, further data are required to confirm these findings.

Management and Outcomes of Traumatic Liver Injury: A Retrospective Analysis from a Tertiary Care Center Experience. Healthcare (Basel) 2024; 12:131. [PMID: 38255020 PMCID: PMC10815392 DOI: 10.3390/healthcare12020131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 12/29/2023] [Accepted: 01/04/2024] [Indexed: 01/24/2024] Open
Abstract
BACKGROUND although liver injuries are one of the most critical complications of abdominal trauma, choosing when to operate on these injuries is challenging for surgeons worldwide. METHODS We conducted a retrospective analysis of liver injury cases at our institution from 2016 to 2022 to describe the operative and nonoperative management (NOM) outcomes in patients with traumatic liver injuries. Baseline patient characteristics, liver injury details, treatments, and outcomes were analyzed. RESULTS Data from 45 patients (male, 77.8%) were analyzed. The mean age was 29.3 years. Blunt trauma was the most common injury mechanism (86.7%), whereas penetrating injuries were 8.9% of cases. Conservative management was associated with 18.9% of complications. The overall complication rate was 26.7%; delirium and sepsis were the most common (13.3%), followed by acute renal failure (4.4%), pneumonia, biliary leaks, and meningitis/seizures. CONCLUSIONS Notwithstanding its limitations, this retrospective analysis demonstrated that NOM can serve as a safe and effective strategy for hemodynamically stable patients with liver trauma, irrespective of the patient's injury grade. Nevertheless, careful patient selection and monitoring are crucial. Further investigations are necessary to thoroughly evaluate the management of traumatic liver injuries, particularly in the context of multiorgan injuries.

Portal vein embolization following arterial portography for the management of an active portal bleeding after blunt liver trauma in a cirrhotic patient. CVIR Endovasc 2024; 7:5. [PMID: 38175362 PMCID: PMC10766936 DOI: 10.1186/s42155-023-00423-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Accepted: 12/19/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND The management of blunt liver trauma in cirrhotic patients is challenging, because while bleeding is most often of arterial origin, the increased pressure in the portal system associated with cirrhosis can increase the risk of portal bleeding, which is sometimes difficult to confirm on contrast-enhanced abdominal computed tomography. CASE PRESENTATION We managed a 54-year-old cirrhotic patient who presented with blunt liver trauma. Computed Tomography showed active intraperitoneal bleeding presumed to be of hepatic origin. Given the patient's hemodynamic stability, the decision was made to manage the patient non-surgically. The patient underwent hepatic arteriography to rule out an arterial origin to the bleeding. A superior mesenteric arterial portography confirmed the portal venous origin of the bleeding. To stop the bleeding, a distal portal vein embolization using coils and glue was performed by approaching a large paraumbilical vein. CONCLUSIONS Our case study shows the value of arterial portography in the management of these patients, when they are clinically stable enough to benefit from non-surgical management; This allows arterial bleeding to be excluded on hepatic arteriography, portal bleeding to be confirmed on portography following arteriography in the superior mesenteric artery, and guidance of portal vein embolization.

Use of angioembolization, treatment modalities and mortality in association with blunt liver trauma in Germany - a data analysis of the TraumaRegister DGU®. Langenbecks Arch Surg 2023; 409:6. [PMID: 38093037 PMCID: PMC10719148 DOI: 10.1007/s00423-023-03196-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Accepted: 12/05/2023] [Indexed: 12/17/2023]
Abstract
PURPOSE Angioembolization (ANGIO) is highly valued in national and international guideline recommendations as a treatment adjunct with blunt liver trauma (BLT). The literature on BLT shows that treatment, regardless of the severity of liver injury, can be accomplished with a high success rate using nonoperative management (NOM). An indication for surgical therapy (SURG) is only seen in hemodynamically instable patients. For Germany, it is unclear how frequently NOM ± ANGIO is actually used, and what mortality is associated with BLT. METHODS A retrospective systematic data analysis of patients with BLT from the TraumaRegister DGU® was performed. All patients with liver injury AIS ≥ 2 between 2015 and 2020 were included. The focus was to evaluate the use ANGIO as well as treatment selection (NOM vs. SURG) and mortality in relation to liver injury severity. Furthermore, independent risk factors influencing mortality were identified, using multivariate logistic regression. RESULTS A total of 2353 patients with BLT were included in the analysis. ANGIO was used in 18 cases (0.8%). NOM was performed in 70.9% of all cases, but mainly in less severe liver trauma (AIS ≤ 2, abbreviated injury scale). Liver injuries AIS ≥ 3 were predominantly treated surgically (64.6%). Overall mortality associated with BLT was 16%. Severity of liver injury ≥ AIS 3, age > 60 years, hemodynamic instability (INSTBL), and mass transfusion (≥ 10 packed red blood cells/pRBC) were identified as independent risk factors contributing to mortality in BLT. CONCLUSION ANGIO is rarely used in BLT, contrary to national and international guideline recommendations. In Germany, liver injuries AIS ≥ 3 are still predominantly treated surgically. BLT is associated with considerable mortality, depending on the presence of specific contributing risk factors.

Abdominal compartment syndrome: what radiologist needs to know. LA RADIOLOGIA MEDICA 2023; 128:1447-1459. [PMID: 37747669 DOI: 10.1007/s11547-023-01724-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Accepted: 09/05/2023] [Indexed: 09/26/2023]
Abstract
The intra-abdominal hypertension (IAH) and the abdominal compartment syndrome (ACS) are life-threatening conditions with a significant rate of mortality; therefore, early detection is paramount in their optimal management. IAH is diagnosed when the intra-abdominal pressure (IAP) is more than 12 mmHg. It can occur when the intra-abdominal volume increases (ileus, ascites, trauma, pancreatitis, etc.) and/or the abdominal wall compliance decreases. IAH can cause decreased venous flow, low cardiac output, renal impairment, and decreased respiratory compliance. Consequently, these complications can lead to multiple organ failure and induce the abdominal compartment syndrome (ACS) when IAP rises above 20 mmHg. The diagnosis is usually made with intravesical pressure measurement. However, this measurement was not always possible to obtain; therefore, alternative diagnostic techniques should be considered. In this setting, computed tomography (CT) may play a crucial role, allowing the detection and characterization of pathological conditions that may lead to IAH. This review is focused on the pathogenesis, clinical features, and radiological findings of ACS, because their presence allows radiologists to raise the suspicion of IAH/ACS in critically ill patients, guiding the most appropriate treatment.

Hepatobiliary-specific magnetic resonance contrast agents: role in biliary trauma. Gland Surg 2023; 12:1425-1433.

Abstract
Non-iatrogenic traumatic bile duct injuries (NI-TBIs) are a rare complication after abdominal trauma, with an estimated prevalence of 2.8-7.4% in patients underwent blunt liver injuries. They may be overlooked in patients with extensive multi-organ trauma, particularly hepatic, splenic and duodenal injuries, which have a prevalence of 91%, 54% and 54%, respectively. Whole body contrast-enhanced computed tomography (CE-CT) represents the examination of choice in polytraumatized hemodynamically stable patients, as it allows a comprehensive evaluation of vascular, parenchymal, bone and soft tissues injuries, but the diagnosis of any biliary leaks is limited to the evaluation of nonspecific imaging findings and on findings evolution in the follow-up, such as the progressive growth of fluid collections. Furthermore, biliary complications, such as the occurrence of biloma or biliary peritonitis, may become manifest several days after the initial trauma, often with unspecific progressive signs and symptoms. Although CT and ultrasonography can suggest bile leaks based on several nonspecific imaging findings (e.g., fluid collections), magnetic resonance imaging (MRI) using hepatobiliary contrast agents helps to identify the site and entity of post-traumatic biliary disruption. Indeed, MRI allows to obtain cholangiographic sequences that may show post-traumatic active bile leakage and cysto-biliary communications by direct visualisation of contrast material extravasation into fluid collections, increasing the preoperative accuracy of NI-TBIs. Few data are available about MRI use in the follow-up of trauma with NI-TBI management. So, in the present mini review, its role is reviewed and our preliminary experience in this field is reported.

Abstract
The liver is one of the most commonly injured solid organs in blunt abdominal trauma. In patients who are hemodynamically normal, most cases of blunt liver injuries are managed conservatively. At present, nonoperative management (NOM) is the standard of care for both minor and severe liver injuries. Usually, patients with severe liver injuries, i.e., grades IV and V, are treated with surgical intervention versus angioembolization depending if patients are hemodynamically stable or not. We present a hemodynamically stable 53-year-old male patient with a grade V blunt liver injury with complete avulsion of the left lobe of the liver after a motor vehicle collision (MVC). Very few cases of complete hepatic avulsions have been published in the literature. We discuss surgical management with stapler-assisted hepatectomy in emergency trauma laparotomy for bleeding control.

Abstract
In the transition from the operative to the conservative approach for the polytraumatized patients who undergo blunt trauma, diagnostic imaging has assumed a pivotal role, currently offering various opportunities, particularly in the follow-up of these patients. The choice of the most suitable imaging method in this setting mainly depends on the injury complications we are looking for, the patient conditions (mobilization, cooperation, medications, allergies and age), the biological invasiveness, and the availability of each imaging method. Computed Tomography (CT) represents the “standard” imaging technique in the polytraumatized patient due to the high diagnostic performance when a correct imaging protocol is adopted, despite suffering from invasiveness due to radiation dose and intravenous contrast agent administration. Ultrasound (US) is a readily available technology, cheap, bedside performable and integrable with intravenous contrast agent (Contrast enhanced US—CEUS) to enhance the diagnostic performance, but it may suffer particularly from limited panoramicity and operator dependance. Magnetic Resonance (MR), until now, has been adopted in specific contexts, such as biliopancreatic injuries, but in recent experiences, it showed a great potential in the follow-up of polytraumatized patients; however, its availability may be limited in some context, and there are specific contraindications, such as as claustrophobia and the presence non-MR compatible devices. In this article, the role of each imaging method in the body-imaging follow-up of adult polytraumatized patients will be reviewed, enhancing the value of integrated imaging, as shown in several cases from our experience.

Accuracy of computed tomography in staging acute appendicitis and its impact on surgical outcome and strategy: a multi-center retrospective case-control study. LA RADIOLOGIA MEDICA 2023; 128:415-425. [PMID: 36940006 DOI: 10.1007/s11547-023-01619-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Accepted: 03/07/2023] [Indexed: 03/21/2023]
Abstract
INTRODUCTION The aims of this study were to evaluate the concordance between AAST-CT appendicitis grading criteria, first published in 2014, and surgical findings and to assess the impact of CT staging on the choice of surgical approach. METHODS This was a multi-center retrospective case-control study including 232 consecutive patients undergoing surgery for acute appendicitis and who had undergone preoperative CT evaluation between 1 January 2017 and 1 January 2022. Appendicitis severity was classified in 5 grades. For each degree of severity, the surgical outcome between patients undergoing open and surgical approach was compared. RESULTS An almost perfect agreement (k = 0.96) was found between CT and surgery in staging acute appendicitis. The vast majority of patients with grade 1 and 2 appendicitis underwent laparoscopic surgical approach and showed low morbidity rate. In patients with grade 3 and 4 appendicitis, laparoscopic approach was adopted in 70% of cases and was associated, if compared to open, with a higher prevalence of postoperative abdominal collections (p = 0.05; fisher's exact test) and a significantly lower prevalence of surgical site infections (p = 0.0007; fisher's exact test). All the patients with grade 5 appendicitis were treated by laparotomy. CONCLUSIONS AAST-CT appendicitis grading system seems to show a relevant prognostic value and a potential impact on the choice of surgical strategy, directing toward a laparoscopic approach in patients with grade 1 and 2, an initial laparoscopic approach, replaceable by the open one, for grade 3 and 4 and an open approach in patients with grade 5.

Abstract
PURPOSE Severe hepatic injury due to gunshot (GSW) compared to blunt mechanism may have significantly different presentation, management, complications, and outcomes. The aim of this study was to identify the differences. METHODS Retrospective single-center analysis June 1, 2015-June 30, 2020, included all patients with Grade III-V liver injuries due to GSW or blunt mechanism. Clinical characteristics, severity of injury, liver-related complications (rebleeding, necrosis/abscess, bile leak/biloma, pseudoaneurysm, acute liver failure) and overall outcomes (mortality, hospital length of stay, intensive care unit length of stay, and ventilatory days) were compared. RESULTS Of 879 patients admitted with hepatic trauma, 347 sustained high-grade injury and were included: 81 (23.3%) due to GSW and 266 (76.7%) due to blunt force. A significantly larger proportion of patients with GSW were managed operatively (82.7 vs. 36.1%, p < 0.001). GSW was associated with significantly more liver-related complications (40.7% vs. 27.4%, p = 0.023), specifically liver necrosis/abscess (18.5% vs. 7.1%, p = 0.003) and bile leak/biloma (12.3% vs. 5.3%, p = 0.028). On subgroup analysis, in patients with grade III injury, the incidence of liver necrosis/abscess and bile leak/biloma remained significantly higher after GSW (13.9% vs. 3.1%, p = 0.008 and 11.1% vs. 2.5%, p = 0.018, respectively). In sub analysis of 88 patients with leading severe liver injuries, GSW had a significantly longer hospital length of stay, ICU length of stay, and ventilator days. CONCLUSION GSW mechanism to the liver is associated with a higher incidence of liver-related complications than blunt force injury.

Abstract
Liver trauma with hemodynamic instability is extremely dangerous. Exploratory surgery after fluid resuscitation is a potentially effective method to save lives. Although there have been great advances in laparoscopic techniques for hepatectomy, laparoscopy is rarely used for liver trauma. According to our previous experience, laparoscopic infrahepatic inferior vena cava (IVC) clamping was a safe and effective technique to reduce central venous pressure (CVP) and control bleeding during hepatectomy. In this article, we described a case of grade V liver trauma that had been managed by an entirely laparoscopic approach using infrahepatic IVC partial clamping, outlining the technique of laparoscopy for liver trauma and the postoperative outcomes.

Abstract
PURPOSE Liver is the most frequently injured organ in abdominal trauma. Today non-operative management (NOM) is considered as the standard of care in hemodynamically stable patients, with or without the adjunct of angioembolisation (AE). This systematic review assesses the incidence of complications in patients who sustained liver injuries and were treated with simple clinical observation. Given the differences in indications of treatment and severity of liver trauma and acknowledging the limitations of this study, an analysis of the results has been done in reference to the complications in patients who were treated with AE. METHODS A systematic literature review searched "liver trauma", "hepatic trauma", "conservative management", "non operative management" on MEDLINE (via PubMed), Cochrane Central Register of Controlled Trials databases, EMBASE, and Google Scholar, to identify studies published on the conservative management of traumatic liver injuries between January 1990 and June 2020. Patients with traumatic liver injuries (blunt and penetrating) treated by NOM, described at least one outcome of interests and provided morbidity outcomes from NOM were included in this study. Studies reported the outcome of NOM without separating liver from other solid organs; studies reported NOM complications together with those post-intervention; case reports; studies including less than 5 cases; studies not written in English; and studies including patients who had NOM with AE as primary management were excluded. Efficacy of NOM and overall morbidity and mortality were assessed, the specific causes of morbidity were investigated, and the American Association for the Surgery of Trauma classification was used in all the studies analysed. Statistical significance has been calculated using the Chi-square test. RESULTS A total of 19 studies qualified for inclusion criteria were in this review. The NOM success rate ranged from 85% to 99%. The most commonly reported complications were hepatic collection (3.1%), followed by bile leak (1.5%), with variability between the studies. Other complications included hepatic haematoma, bleeding, fistula, pseudoaneurysm, compartment syndrome, peritonitis, and gallbladder ischemia, all with an incidence below 1%. CONCLUSION NOM with simple clinical observation showed an overall low incidence of complications, but higher for bile leak and collections. In patients with grade III and above injuries, the incidence of bile leak, collections and compartment syndrome did not show a statistically significant difference with the AE group. However, the latter result is limited by the small number of studies available and it requires further investigations.

Abstract
Major trauma is an event causing injuries that may determine an immediate or potential risk to the patient survival. A correct management of major trauma is decisive in reducing disability, which has relevance both from the point of view of the quality of life of the single individual and from the point of view of health expenditure. The primary clinical approach to the polytraumatized patients is managed, in most cases, as outlined in the guidelines of Advanced Trauma Life Support, proposing conventional radiological investigations, such as chest and pelvis x-ray, and of FAST (focused abdominal sonography in trauma)/E-FAST (extended FAST) examinations, followed by selective targeted computed tomography (CT). This approach is questionable and is increasingly common in clinical practice the adoption of the immediate total-body CT in the diagnostic approach to the hemodynamically stable polytraumatized patient. However, the potential advantages of such conduct both in terms of clinical benefits and in terms of cost-effectiveness still need to be discussed. The objective of this review article consists of a descriptive analysis of the economic and clinical benefits of the adoption of immediate total-body CT in polytrauma patients through a literature review.

Liver Trauma: Until When We Have to Delay Surgery? A Review. Life (Basel) 2022; 12:life12050694.

Abstract
Liver involvement after abdominal blunt trauma must be expected, and in up to 30% of cases, spleen, kidney, and pancreas injuries may coexist. Whenever hemodynamics conditions do not contraindicate the overcoming of the ancient dogma according to which exploratory laparotomy should be performed after every major abdominal trauma, a CT scan has to clarify the liver lesions so as to determine the optimal management strategy. Except for complete vascular avulsion, no liver trauma grade precludes nonoperative management. Every attempt to treat the injured liver by avoiding a strong surgical approach may be considered. Each time, a nonoperative management (NOM) consisting of a basic “wait and see” attitude combined with systemic support and blood replacement are inadequate. Embolization should be considered to stop the bleeding. Percutaneous drainage of collections, endoscopic retrograde cholangiopancreatography (ERCP) with papilla sphincterotomy or stent placement and percutaneous transhepatic biliary drainage (PTBD) may avoid, or at least delay, surgical reconstruction or resection until systemic and hepatic inflammatory remodeling are resolved. The pathophysiological principle sustaining these leanings is based on the opportunity to limit the further release of cell debris fragments acting as damage-associated molecular patterns (DAMPs) and the following stress response associated with the consequent immune suppression after trauma. The main goal will be a faster recovery combined with limited cell death of the liver through the ischemic events that may directly follow the trauma, exacerbated by hemostatic procedures and surgery, in order to reduce the gross distortion of a regenerated liver.

Validity of the scoring system for traumatic liver injury: a generalized estimating equation analysis. JOURNAL OF TRAUMA AND INJURY 2022.

Abstract
Purpose: The scoring system for traumatic liver injury (SSTLI) was developed in 2015 to predict mortality in patients with polytraumatic liver injury. This study aimed to validate the SSTLI as a prognostic factor in patients with polytrauma and liver injury through a generalized estimating equation analysis. Methods: The medical records of 521 patients with traumatic liver injury from January 2015 to December 2019 were reviewed. The primary outcome variable was in-hospital mortality. All the risk factors were analyzed using multivariate logistic regression analysis. The SSTLI has five clinical measures (age, Injury Severity Score, serum total bilirubin level, prothrombin time, and creatinine level) chosen based on their predictive power. Each measure is scored as 0–1 (age and Injury Severity Score) or 0–3 (serum total bilirubin level, prothrombin time, and creatinine level). The SSTLI score corresponds to the total points for each item (0–11 points). Results: The areas under the curve of the SSTLI to predict mortality on post-traumatic days 0, 1, 3, and 5 were 0.736, 0.783, 0.830, and 0.824, respectively. A very good to excellent positive correlation was observed between the probability of mortality and the SSTLI score (γ=0.997, P<0.001). A value of 5 points was used as the threshold to distinguish low-risk (<5) from high-risk (≥5) patients. Multivariate analysis using the generalized estimating equation in the logistic regression model indicated that the SSTLI score was an independent predictor of mortality (odds ratio, 1.027; 95% confidence interval, 1.018–1.036; P<0.001). Conclusions: The SSTLI was verified to predict mortality in patients with polytrauma and liver injury. A score of ≥5 on the SSTLI indicated a high-risk of post-traumatic mortality.

Abstract
Trauma is one of the most common causes of death or permanent disability in young people, so a timely diagnostic approach is crucial. In polytrauma patients, CEUS (contrast enhanced ultrasound) has been shown to be more sensitive than US (ultrasound) for the detection of solid organ injuries, improving the identification and grading of traumatic abdominal lesions with levels of sensitivity and specificity similar to those seen with MDCT (multidetector tomography). CEUS is recommended for the diagnostic evaluation of hemodynamically stable patients with isolated blunt moderate-energy abdominal traumas and the diagnostic follow-up of conservatively managed abdominal traumas. In this pictorial review, we illustrate the advantages and disadvantages of CEUS and the procedure details with tips and tricks during the investigation of blunt moderate-energy abdominal trauma as well as during follow-up in non-operative management.

Abstract
In industrialized countries, high energy trauma represents the leading cause of death and disability among people under 35 years of age. The two leading causes of mortality are neurological injuries and bleeding. Clinical evaluation is often unreliable in determining if, when and where injuries should be treated. Traditionally, surgery was the mainstay for assessment of injuries but advances in imaging techniques, particularly in computed tomography (CT), have contributed in progressively changing the classic clinical paradigm for major traumas, better defining the indications for surgery. Actually, the vast majority of traumas are now treated nonoperatively with a significant reduction in morbidity and mortality compared to the past. In this sense, another crucial point is the advent of interventional radiology (IR) in the treatment of vascular injuries after blunt trauma. IR enables the most effective nonoperative treatment of all vascular injuries. Indications for IR depend on the CT evidence of vascular injuries and, therefore, a robust CT protocol and the radiologist's expertise are crucial. Emergency and IR radiologists form an integral part of the trauma team and are crucial for tailored management of traumatic injuries.

A novel inflatable device for perihepatic packing and hepatic hemorrhage control: A proof-of-concept study. Injury 2022; 53:103-111. [PMID: 34507832 DOI: 10.1016/j.injury.2021.08.027] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2021] [Revised: 08/04/2021] [Accepted: 08/24/2021] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Uncontrolled bleeding is the primary cause of death in complex liver trauma and perihepatic packing is regularly utilized for hemorrhage control. The purpose of this study was to investigate the effectiveness of a novel inflatable device (the airbag) for perihepatic packing using a validated liver injury damage control model in swine. MATERIAL AND METHODS The image of the human liver was digitally isolated within an abdominal computerized tomography scan to produce a silicone model of the liver to mold the airbag. Two medical grade polyurethane sheets were thermal bonded to the configuration of the liver avoiding compression of the hepatic pedicle, hepatic veins, and the suprahepatic vena cava after inflation. Yorkshire pigs (n = 22) underwent controlled hemorrhagic shock (35% of the total blood volume), hypothermia, and fluid resuscitation to reproduce the indications for damage control surgery (coagulopathy, hypothermia, and acidosis) prior to a liver injury. A 3 × 10 cm rectangular segment of the left middle lobe of the liver was removed to create the injury. Subsequently, the animals were randomized into 4 groups for liver damage control (240 min), Sponge Pack (n = 6), Pressurized Airbag (n = 6), Vacuum Airbag (n = 6), and Uncontrolled (n = 4). Animals were monitored throughout the experiment and blood samples obtained. RESULTS Perihepatic packing with the pressurized airbag led to significantly higher mean arterial pressure during the liver damage control phase compared to sponge pack and vacuum airbag 52 mmHg (SD 2.3), 44.9 mmHg (SD 2.1), and 32 mmHg (SD 2.3), respectively (p < 0.0001), ejection fraction was also higher in that group. Hepatic hemorrhage was significantly lower in the pressurized airbag group compared to sponge pack, vacuum airbag, and uncontrolled groups; respectively 225 ml (SD 160), 611 ml (SD 123), 991 ml (SD 385), 1162 ml (SD 137) (p < 0001). Rebleeding after perihepatic packing removal was also significantly lower in the pressurized airbag group; respectively 32 ml (SD 47), 630 ml (SD 185), 513 ml (SD 303), (p = 0.0004). Intra-abdominal pressure remained similar to baseline, 1.9 mmHg (SD 1), (p = 0.297). Histopathology showed less necrosis at the border of the liver injury site with the pressurized airbag. CONCLUSION The pressurized airbag was significantly more effective at controlling hepatic hemorrhage and improving hemodynamics than the traditional sponge pack technique. Rebleeding after perihepatic packing removal was negligible with the pressurized airbag and it did not provoke hepatic injury.

Abstract
BACKGROUND There is variability regarding the utilization and timing of repeat imaging in adult patients with blunt hepatic injury who are managed nonoperatively. This study examines the rate of delayed complications and interventions in patients with blunt hepatic injuries who undergo repeat imaging prompted either by clinical change (CC) or non-clinical change (NCC). METHODS A nine-year, retrospective, dual-institution study was performed of adult patients with blunt hepatic injuries. Patients were identified based on whether repeat imaging was performed and reason for reimaging: CC or NCC. The incidence of delayed complications and interventions was examined for each type of scan. RESULTS Of 365 patients, 122 (33.4%) underwent repeat imaging [CC, n = 72 (59%); NCC, n=50 (41%)]. Mean time to repeat imaging was shorter in the NCC group [CC = 7.6 ± 8 days; NCC = 4.7 ± 6.3 days, P = 0.034]. Delayed complications were found in 30 (25%) patients reimaged, [CC, n = 20; NCC, n = 10, P = 0.395]. Interventions were performed in 12 (40%) patients [CC, n = 10; NCC, n = 2, P = 0.120]. CONCLUSIONS Repeat imaging due to NCC occurred earlier than imaging performed by CC. One quarter of patients reimaged demonstrated a delayed complication, with nearly half undergoing intervention. There was no difference in incidence of delayed complications or interventions between groups, suggesting repeat imaging can be prompted by clinical change in blunt hepatic injuries.

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

Abstract
Background Transcatheter arterial embolization (TAE) is the first-line nonsurgical treatment for severe blunt liver injury in patients, whereas operative management (OM) is recommended for hemodynamically unstable patients. This study investigated the comparative efficacy of TAE in hemodynamically unstable patients who responded to initial infusion therapy. Methods This retrospective study enrolled patients with severe blunt liver injuries, which were of grades III–V according to the American Association for the Surgery of Trauma Organ Injury Scale (OIS). Patients who responded to initial infusion therapy underwent computed tomography to determine the treatment plan. A shock index > 1, despite undergoing initial infusion therapy, was defined as hemodynamic instability. We compared the clinical outcomes and mortality rates between patients who received OM and those who underwent TAE. Results Sixty-two patients were included (eight and 54 who underwent OM and TAE, respectively; mean injury severity score, 26.6). The overall in-hospital mortality rate was 6% (13% OM vs. 6% TAE, p = 0.50), and the hemodynamic instability was 35% (88% OM vs. 28% TAE, p < 0.01). Hemodynamically unstable patients who underwent TAE had 7% in-hospital mortality and 7% clinical failure. Logistic regression analysis showed that the treatment choice was not a predictor of outcome, whereas hemodynamic instability was an independent predictor of intensive care unit stay ≥7 days (odds ratio [OR], 3.80; p = 0.05) and massive blood transfusion (OR, 7.25; p = 0.01); OIS grades IV–V were predictors of complications (OR, 6.61; p < 0.01). Conclusions TAE in hemodynamically unstable patients who responded to initial infusion therapy to some extent has acceptable in-hospital mortality and clinical failure rates. Hemodynamic instability and OIS, but not treatment choice, affected the clinical outcomes.

Abstract
Liver injury is a common consequence of blunt abdominopelvic trauma. Contrast-enhanced CT allows for the rapid detection and evaluation of liver injury. The treatment strategy for blunt liver injury has shifted from surgical to nonoperative management, which has been widely complemented by interventional management to treat both liver injury and its complications. In this article, we review the major imaging features of liver injury and the role of interventional management for the treatment of liver injury.

Abstract
BACKGROUND Hepatobiliary surgery and hepatic trauma are frequent causes of bile leaks and this feared complication can be safely managed by endoscopic retrograde cholangiopancreatography (ERCP). The approach consists of sphincterotomy alone, biliary stenting or a combination of the two but the optimal form remains unclear. OBJECTIVE The aim of this study is to compare sphincterotomy alone versus sphincterotomy plus biliary stent placement in the treatment of post-surgical and traumatic bile leaks. METHODS We retrospectively analyzed 31 patients with the final ERCP diagnosis of "bile leak". Data collected included patient demographics, etiology of the leak and the procedure details. The treatment techniques were divided into two groups: sphincterotomy alone vs. sphincterotomy plus biliary stenting. We evaluated the volume of the abdominal surgical drain before and after each procedure and the number of days needed until cessation of drainage post ERCP. RESULTS A total of 31 patients (18 men and 3 women; mean age, 51 years) with bile leaks were evaluated. Laparoscopic cholecystectomy was the etiology of the leak in 14 (45%) cases, followed by conventional cholecystectomy in 9 (29%) patients, hepatic trauma in 5 (16%) patients, and hepatectomy secondary to neoplasia in 3 (9.7%) patients. The most frequent location of the leaks was the cystic duct stump with 12 (38.6%) cases, followed by hepatic common duct in 10 (32%) cases, common bile duct in 7 (22%) cases and the liver bed in 2 (6.5%) cases. 71% of the patients were treated with sphincterotomy plus biliary stenting, and 29% with sphincterotomy alone. There was significant difference between the volume drained before and after both procedures (P<0.05). However, when comparing sphincterotomy alone and sphincterotomy plus biliary stenting, regarding the volume drained and the days needed to cessation of drainage, there was no statistical difference in both cases (P>0.005). CONCLUSION ERCP remains the first line treatment for bile leaks with no difference between sphincterotomy alone vs sphincterotomy plus stent placement.

Abstract
OBJECTIVES To obtain information from radiology departments throughout Europe regarding the practice of emergency radiology METHODS: A survey which comprised of 24 questions was developed and made available online. The questionnaire was sent to 1097 chairs of radiology departments throughout Europe using the ESR database. All data were collected and analyzed using IBM SPSS Statistics software, version 20 (IBM). RESULTS A total of 1097 radiologists were asked to participate, 109 responded to our survey. The response rate was 10%. From our survey, 71.6% of the hospitals had more than 500 beds. Ninety-eight percent of hospitals have an active teaching affiliation. In large trauma centers, emergency radiology was considered a dedicated section. Fifty-three percent of institutions have dedicated emergency radiology sections. Less than 30% had all imaging modalities available. Seventy-nine percent of institutions have 24/7 coverage by staff radiologists. Emergency radiologists interpret cross-sectional body imaging, US scans, and basic CT/MRI neuroimaging in more than 50% of responding institutions. Cardiac imaging examinations/procedures are usually performed by cardiologist in 53% of institutions, while non-cardiac vascular procedures are largely performed and interpreted by interventional radiologists. Most people consider the European Diploma in Emergency Radiology an essential tool to advance the education and the dissemination of information within the specialty of emergency radiology. CONCLUSION Emergency radiologists have an active role in the emergency medical team. Indeed, based upon our survey, they have to interact with emergency physicians and surgeons in the management of critically ill patients. A broad skillset from ultrasonography and basic neuroimaging is required. KEY POINTS • At most major trauma centers in Europe, emergency imaging is currently performed by all radiologists in specific units who are designated in the emergency department. • Radiologists in the emergency section at present have a broad skillset, which includes cross-sectional body imaging, ultrasonography, and basic neuroimaging of the brain and spine. • A dedicated curriculum that certifies a subspecialty in emergency radiology with a diploma offered by the European Society of Emergency Radiology demonstrates a great interest by the vast majority of the respondents.

Abstract
Liver injuries represent one of the most frequent life-threatening injuries in trauma patients. In determining the optimal management strategy, the anatomic injury, the hemodynamic status, and the associated injuries should be taken into consideration. Liver trauma approach may require non-operative or operative management with the intent to restore the homeostasis and the normal physiology. The management of liver trauma should be multidisciplinary including trauma surgeons, interventional radiologists, and emergency and ICU physicians. The aim of this paper is to present the World Society of Emergency Surgery (WSES) liver trauma management guidelines.

Abstract
PURPOSE In the literature, no consensus exists about which CT protocol is to be adopted in patients who underwent high-energy blunt trauma. The aim of the study is to evaluate the additional value of the arterial phase in the CT assessment of vascular injuries of the liver. METHODS Admission CT examinations for patients with traumatic injury of the liver due to high-energy blunt trauma, performed between 2011 and 2017 in two major trauma centres, were retrospectively reviewed. Images were analysed for presence or absence of liver parenchymal injury, intrahepatic contained vascular injuries and active bleeding in the arterial and portal venous phase of the CT study. RESULTS Two hundred twelve patients have been identified. Parenchymal injuries were detected as isolated in 90.6% of cases, whereas they were associated with vascular injuries in 9.4% of cases: contained vascular injuries in 3.3% and active bleeding in 6.1%. Out of all parenchymal injuries detected on the CT portal venous phase, 90.5% were also detectable in the arterial phases (p < 0.0001). All of the contained vascular injuries were visible in the CT arterial phase, whereas they were detectable in 28.5% of cases also during the venous phase (p = 0.02). All 13 cases of active bleeding were detected on the CT venous phase, and 76.9% of these cases were also revealed in the arterial phase, thus confirming their arterial origin (p = 0.22). CONCLUSION The addiction of the arterial phase to the venous phase in the CT assessment of patients who underwent high-energy blunt trauma allows an accurate identification and characterization of traumatic vascular injuries, so distinguishing between patients suitable for conservative management and those requiring interventional or surgical treatment.

Abstract
Purpose. To evaluate the results of Damage Control Strategy (DCS) in the treatment of generalized peritonitis from perforated diverticular disease in patients with preoperative severe systemic diseases. Methods. All the patients with diffuse peritonitis (Hinchey 3 and 4) and the American Society of Anesthesiologists (ASA) score ≥3 were included and underwent DCS consisting of a 2-step procedure. The first was peritoneal lavage, perforated colon-stapled resection, and temporary abdominal closure with negative pressure wound therapy combined with instillation. The second step, 48 hours later, included the possibility of restoring intestinal continuity basing on local and general patients' conditions. Results. Thirty patients (18 [60%] women and 12 [40%] men, median age 68.5 [range = 35-84] years) were included (18 [60%] ASA III, 11 [36.7%] ASA IV, and 1 [0.03%] ASA V). Seven patients (23.3%) showed sepsis and 1 (3.33%) septic shock. At second surgery, 24 patients (80%) received a colorectal anastomosis and 6 patients (20%) underwent a Hartmann's procedure. Median hospital stay was 18 days (range = 12-62). Postoperative morbidity rate was 23.3% (7/30) and included 1 anastomotic leak treated with Hartmann's procedure. Consequently, at discharge from hospital, 23 patients (76.6%) were free of stoma. Primary fascial closure was possible in all patients. Conclusions. DCS with temporary abdominal closure by negative pressure wound therapy combined with instillation in patients with diffuse peritonitis from complicated diverticulitis could represent a feasible surgical option both in hemodynamically stable and no stable patients, showing encouraging results including a low stoma rate and an acceptable morbidity rate.

Abstract
Background A widespread shift to non-operative management (NOM) for blunt hepatic and splenic injuries has been observed in most centers worldwide. Furthermore, many countries introduced safety measures to systematically reduce severe traffic and leisure sports injuries. This study aims to evaluate the effect of these nationwide implementations on individual patient characteristics and outcomes through a time-trend analysis over 17 years in an Austrian high-volume trauma center. Methods A retrospective review of all emergency trauma patients admitted to the Medical University of Innsbruck from 2000 to 2016. Injury severity, clinical data on admission, operative and non-operative treatment parameters, complications, and in-hospital mortality were evaluated. Results In total, 731 patients were treated with blunt hepatic and/or splenic injuries. Among these, 368 had a liver injury, 280 splenic injury, and 83 combined hepatic/splenic injury. Initial NOM was performed in 82.6% of all patients (93.5% in hepatic and 71.8% in splenic injuries) with a success rate of 96.7%. The secondary failure rate of NOM was 3.3% and remained consistent over 17 years (p = 0.515). In terms of injury severity, we observed a reduction over time, resulting in an overall mortality rate of 4.8% and 3.5% in the NOM group (decreasing from 7.5 to 1.9% and from 5.6 to 1.3%, respectively). These outcomes confirmed an improved utilization of the NOM approach. Conclusion Our cohort represents one of the largest Central European single-center experiences available in the literature. NOM is the standard of care for blunt hepatic and splenic injuries and successful in > 96% of all patients. This rate was quite constant over 17 years (p = 0.515). Overall, national and regional safety measures resulted in a significantly decreased severity of observed injury patterns and deaths due to blunt hepatic or splenic trauma. Although surgery is nowadays only applied in about one third of splenic injury patients in our center, these numbers might further decrease by intensified application of interventional radiology and modern coagulation management.
