JOURNAL OF IMAGING INFORMATICS IN MEDICINE 2024; 37:1113-1123. [PMID: 38366294 DOI: 10.1007/s10278-024-01038-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/25/2023] [Revised: 01/31/2024] [Accepted: 02/01/2024] [Indexed: 02/18/2024]
Abstract
Computed tomography (CT) is the most commonly used diagnostic modality for blunt abdominal trauma (BAT), significantly influencing management approaches. Deep learning models (DLMs) have shown great promise in enhancing various aspects of clinical practice. There is limited literature available on the use of DLMs specifically for trauma image evaluation. In this study, we developed a DLM aimed at detecting solid organ injuries to assist medical professionals in rapidly identifying life-threatening injuries. The study enrolled patients from a single trauma center who received abdominal CT scans between 2008 and 2017. Patients with spleen, liver, or kidney injury were categorized as the solid organ injury group, while others were considered negative cases. Only images acquired from the trauma center were enrolled. A subset of images acquired in the last year was designated as the test set, and the remaining images were utilized to train and validate the detection models. The performance of each model was assessed using metrics such as the area under the receiver operating characteristic curve (AUC), accuracy, sensitivity, specificity, positive predictive value, and negative predictive value based on the best Youden index operating point. The study developed the models using 1302 (87%) scans for training and tested them on 194 (13%) scans. The spleen injury model demonstrated an accuracy of 0.938 and a specificity of 0.952. The accuracy and specificity of the liver injury model were reported as 0.820 and 0.847, respectively. The kidney injury model showed an accuracy of 0.959 and a specificity of 0.989. We developed a DLM that can automate the detection of solid organ injuries by abdominal CT scans with acceptable diagnostic accuracy. It cannot replace the role of clinicians, but we can expect it to be a potential tool to accelerate the process of therapeutic decisions for trauma care.

Br J Radiol 2024; 97:386-391. [PMID: 38302092 DOI: 10.1093/bjr/tqad060] [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: 08/17/2023] [Revised: 11/23/2023] [Accepted: 12/20/2023] [Indexed: 02/03/2024] Open
Abstract
OBJECTIVE To explore the feasibility of using marking and fusion image-guided technique with cone-beam CT (CBCT) in cases of kidney ruptured haemorrhage without extravascular leakage in digital subtraction angiography (DSA) images. METHODS This is a retrospective case-control study that included 43 patients who underwent transcatheter arterial embolization for kidney ruptured haemorrhage and difficult haemostasis. The patients were divided into two groups: the CBCT group (cases without extravascular leakage observed in angiography) and the control group (cases with clearly identifiable target vessels in angiography). The baseline characteristics and clinical outcomes were collected and analysed. RESULTS The results showed no statistically significant differences in the duration of the procedure and intraoperative blood transfusion between the control and CBCT groups (P > .05). The study clarified that the CBCT group had a significantly higher rate of improvement of gross haematuria compared to the control group (P < .05). The CBCT group showed a greater increase in haemoglobin and a lesser increase in creatinine. The clinical success rates were 87.5% in the control group and 90.9% in the CBCT group (P > .05). CONCLUSIONS The marking and fusion image-guided technique is useful in cases of kidney ruptured haemorrhage without extravascular leakage of contrast agent. The technique is safe, feasible, and effective, and we believe it is superior to purely DSA-guidance. ADVANCES IN KNOWLEDGE The use of the marking and fusion image-guided technique is recommended to overcome the challenge of undetectable target vessels during interventional procedures. This technique is considered as non-inferior to purely DSA-guided interventional procedures where the target vessels are clearly identifiable.

Abstract
Purpose: To explore the influence of milk fat globule-EGF factor 8 protein (MFGE8) on blunt abdominal injury in Sprague Dawley (SD) rats through the RhoA/ROCK signaling pathway. Methods: The blunt abdominal injury model was generated in SD rats. A total of 44 rats was randomly assigned into three groups. Rat blunt abdominal injury was assessed by the abbreviated injury scale (AIS). The rats were sacrificed for observing the morphology of the abdominal cavity and intestines. Hematoxylin and eosin staining was performed to visualize the pathological changes of rat intestines. Positive expressions of MFGE8 and high mobility group box 1 (HMGB1) in rat intestines were examined by immunohistochemical staining. Protein levels were determined by Western blot. Serum levels of tumor necrosis factor α (TNF-α), IL-1β, IL-6 and malondialdehyde (MDA) were measured by enzyme linked immunosorbent assay (ELISA). Results: Blunt abdominal injury resulted in inflammatory response of intestinal tissues, increased serum levels of TNF-α, IL-1β, IL-6 and MDA, upregulation of HMGB1, RhoA and ROCK2, and downregulation of MFGE8 in rats, which were significantly alleviated by intervention of rhMFGE8. Conclusions: MFGE8 protects the intestinal mucosal barrier function after blunt abdominal injury in rats by downregulating HMGB1. Moreover, it alleviates inflammatory response and oxidative stress caused by blunt abdominal injury in rats through downregulating RhoA and ROCK.

Abstract
Background Massive bleeding is a major preventable cause of early death in trauma. It often requires surgical and/or endovascular intervention. We aimed to describe the utilization of angioembolization in patients with abdominal and pelvic traumatic bleeding at a level 1 trauma center. Methods We conducted a retrospective analysis for all trauma patients who underwent angioembolization post-traumatic bleeding between January 2012 and April 2018. Patients’ data and details of injuries, angiography procedures and outcomes were extracted from the Qatar national trauma registry. Results A total of 175 trauma patients underwent angioembolization during the study period (103 for solid organ injury, 51 for pelvic injury and 21 for other injuries). The majority were young males. The main cause of injury was blunt trauma in 95.4% of the patients. The most common indication of angioembolization was evident active bleeding on the initial CT scan (contrast pool or blushes). Blood transfusion was needed in two-third of patients. The hepatic injury cases had higher ISS, higher shock index and more blood transfusion. Absorbable particles (Gelfoam) were the most commonly used embolic material. The overall technical and clinical success rate was 93.7% and 95%, respectively, with low rebleeding and complication rates. The hospital and ICU length of stay were 13 and 6 days, respectively. The median injury to intervention time was 320 min while hospital arrival to intervention time was 274 min. The median follow-up time was 215 days. The overall cohort mortality was 15%. Conclusion Angioembolization is an effective intervention to stop bleeding and support nonoperative management for both solid organ injuries and pelvic trauma. It has a high success rate with a careful selection and proper implementation.

Value of repeat CT for nonoperative management of patients with blunt liver and spleen injury: a systematic review. Eur J Trauma Emerg Surg 2021; 47:1753-1761. [PMID: 33484276 DOI: 10.1007/s00068-020-01584-x] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2020] [Accepted: 12/27/2020] [Indexed: 10/22/2022]
Abstract
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
BACKGROUND The aim of this study was to evaluate the management strategies and outcomes of isolated severe pelvic fractures in level I and II ACS verified trauma centers. METHODS ACS-TQIP database study, including patients with blunt, isolated severe pelvic facture (AIS 3-5). RESULTS 2629 level I and 1277 level II patients were included. Early blood product transfusion was significantly higher, pharmacological VTE prophylaxis significantly lower and ICU length of stay significantly longer in level II centers (p < 0.001). On multivariate analysis, treatment at level II centers was independently associated with increased overall complications, specifically ARDS, but not mortality. CONCLUSIONS In isolated severe pelvic fractures there was a significantly higher use of early blood products, less VTE pharmacological prophylaxis, longer ICU length of stay and higher overall complications and ARDS in level II centers. Blood product utilization and pharmacological VTE prophylaxis are potential areas of quality improvement in level II centers.

Abstract
Objectives Despite the low incidence of pancreatic injury in the abdominal blunt trauma (BTA), its early diagnosis is very important; since pancreatic injury is associated with high rates of morbidity and mortality. However, due to the high association of pancreatic injury with injury of other abdominal organs, its diagnosis may be delayed and complicated. The use of imaging modalities is also subject to limitations for reasons such as cost, unavailability, and harmfulness. Consequently, the present study aimed to investigate the predictive role of amylase and lipase enzyme levels in the final diagnosis of pancreatic injury in patients with BTA. Methods In a prospective diagnostic study, 384 patients with BTA referring to Imam Khomeini hospital of Sari (north of Iran) were enrolled according to the inclusion and exclusion criteria. Initial patient data including age and sex were recorded. Blood samples were analyzed in the laboratory to measure complete blood count (CBC), amylase and lipase enzyme levels. Patients were followed up during hospitalization and focal ultrasound for abdominal trauma (FAST), CT-Scan and laparotomy results were recorded. Finally, the data was analyzed using SPSS version 22. Results The level of amylase enzyme was significantly higher in males (p = 0.04), but the level of lipase enzyme was not significantly different between two genders (p > 0.05). The most common symptoms and signs in patients were pain, tenderness, and hematoma, respectively. The frequency of pancreatic injury in all patients with blunt abdominal trauma was 7.5% based of FAST, 7% based on CT-Scan and 12.4% based on laparotomy. Comparison of laboratory findings based on FAST, CT-Scan and laparotomy results showed that the level of amylase and lipase enzymes in patients with internal organ and pancreatic damage were higher than in patients without internal organ injury (p < 0.05). But based on FAST results; patients with pancreatic injury and injury of other organs had no significant difference (p > 0.05). However, comparison of laboratory findings based on CT-Scan and laparotomy results showed a significant increase in the level of amylase and lipase enzymes in patients with pancreatic trauma compared to patients with injury of other organs (p < 0.001). Conclusions The results of this study showed that pancreatic injury in blunt trauma is associated with a significant increase in levels of amylase and lipase enzymes. In addition, an increase in levels of amylase and lipase enzymes is associated with internal organ damage. Serum amylase and lipase levels can be used as useful biomarkers to decide whether to perform CT-Scan or laparotomy.

Abstract
Blunt abdominal trauma often presents a diagnostic challenge. Clinical examination demonstrates low reliability in detecting abdominal injury (16 %) when there is a history of head injury or loss of consciousness. This can prove detrimental, as delays in the diagnosis of traumatic bowel injury of 8 h or less can result in increased morbidity and mortality, as well as prolonged hospitalization. Although hemodynamically unstable patients will require an urgent laparotomy following clinical assessment, MDCT is the modality of choice for comprehensive imaging of blunt abdominal trauma in hemodynamically stable patients. Despite the use of MDCT, blunt injury to the bowel and mesentery, which accounts for up to 5% of injuries in cases of trauma, may be difficult to detect. The use of a constellation of direct and indirect signs on MDCT can help make the diagnosis and guide clinical management. Direct signs on MDCT, such as bowel wall discontinuity, and extraluminal gas may assist in the diagnosis of traumatic bowel injury. However, these signs are not sensitive. Therefore, the astute radiologist may have to rely on indirect signs of injury, such as free fluid, bowel wall thickening, and abnormal bowel wall enhancement to make the diagnosis. This review will focus on MDCT imaging findings of bowel and mesenteric injuries secondary to blunt abdominal trauma.

Abstract
Emergent exploratory laparotomy is recommended for hemodynamically unstable blunt trauma patients suspected of having hemoperitoneum. However, given the unreliability of ultrasonography and rapid scan speed of computed tomography (CT), CT might help clinicians provide accurate information even in hemodynamically unstable trauma patients. This observational study aimed to describe the bleeding site and hospital course of severe blunt trauma patients with hemoperitoneum diagnosed by CT scan.We enrolled all consecutive adult blunt trauma patients (≥18 years old) who underwent whole-body CT before operation between February 2012 and October 2016. Patients with hemoperitoneum on CT images were included and categorized into hemodynamically stable and unstable (persistent hypotension despite fluid resuscitation) groups.Among 1723 severe blunt trauma patients, 136 patients with hemoperitoneum were included. Of these, 98 (72.1%) patients had documented intraperitoneal injury, and the liver (60.2%) was most frequently damaged site, followed by spleen (23.5%) and mesentery (23.5%). The rate of intraperitoneal organ injury did not differ between hemodynamically stable (n = 107) and unstable (n = 29) groups (69.2% vs 82.8%, P = .15), while the documented active internal bleeding was high in the unstable group (29.9% vs 69.0%, P < .001). In the unstable group, 14 (48.3%) patients underwent emergent operation, while 3 patients underwent embolization, and the others were treated in a conservative manner.Even in hemodynamically unstable hemoperitoneum patients, 17.2% had no documented intraperitoneal injury and over half of the patients were treated without emergent operation.

Abstract
Abdominopelvic trauma (APT) remains a leading cause of morbidity and mortality in the 15- to 44-year-old age group in the Western World. It can be life-threatening as abdominopelvic organs, specifically those in the retroperitoneal space, can bleed profusely. APT is divided into blunt and penetrating types. While surgery is notably considered as a definitive solution for bleeding control, it is not always the optimum treatment for the stabilization of a polytrauma patient. Over the past decades, there has been a shift toward more sophisticated strategies, such as non-operative management of abdominopelvic vascular trauma for haemodynamically stable patients. Angiographic embolization for bleeding control following blunt and/or penetrating intra- and retroperitoneal injuries has proven to be safe and effective. Embolization can achieve hemostasis and salvage organs without the morbidity of surgery, and the development and refinement of embolization techniques has widened the indications for non-operative treatment in solid organ injury. Moreover, advances in computed tomography provided more efficient scanning times with improved image quality. While surgery is still usually recommended for patients with penetrating injuries, non-operative management can be effectively used as well as an alternative treatment. We review indications, technical considerations, efficacy, and complication rates of angiographic embolization in APT.

Electron Physician 2016; 8:2793-2801. [PMID: 27757191 PMCID: PMC5053462 DOI: 10.19082/2793] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2016] [Accepted: 06/18/2016] [Indexed: 11/20/2022] Open
Abstract
Introduction Clinical practice guidelines are structured recommendations that help physicians and patients to make proper decisions when dealing with a specific clinical condition. Because blunt abdominal trauma causes a various range of mild, single-system, and multisystem injuries, early detection will help to reduce mortality and resulting disability. Emergency treatment should be initiated based on CPGs. This study aimed to determine the variables affecting implementing blunt abdominal trauma CPGs in an Iranian hospital. Methods This study was conducted as a qualitative and phenomenology study in the Family Hospital in Tehran (Iran) in 2015. The research population included eight experts and key people in the area of blunt abdominal trauma clinical practice guidelines. Sampling was based on purposive and nonrandom methods. A semistructured interview was done for the data collection. A framework method was applied for the data analysis by using Atlas.ti software. Results After framework analyzing and various reviewing and deleting and combining the codes from 251 codes obtained, 15 families and five super families were extracted, including technical knowledge barriers, economical barriers, barriers related to deployment and monitoring, political will barriers, and managing barriers. Conclusion Structural reform is needed for eliminating the defects available in the healthcare system. As with most of the codes, subconcepts and concepts are classified into the field of human resources; it seems that the education and knowledge will be more important than other resources such as capital and equipment.

Abstract
INTRODUCTION Non-operative management is the standard of care for blunt solid organ injuries in stable patients. Angioembolization is an important technique that improves success rates of non-operative management. We aimed to provide a brief review of the indications, effectiveness and complications associated with angioembolization for solid organ injuries. METHODS We conducted a literature search of the PubMed database using the terms "trauma", "angioembolization", and "solid organ embolization" limited to studies published in the English language. Abstracts and full text were manually reviewed to identify suitable articles. RESULTS The current brief review is based on content from the more recently published articles related to angioembolization for solid organ injuries after trauma. DISCUSSION Angioembolization is appropriate for hemodynamically stable patients with contrast extravasation on CT scan or high-grade injury to a solid organ. Non-operative management success rates have improved with the adoption of angioembolization. The complications associated with angioembolization are acceptable in the context of avoiding a laparotomy, and are often related to the severity of the injury. CONCLUSION Angioembolization is a natural extension of the move towards non-operative management for solid organ injuries. Randomized controlled trials are required to fully characterize the indications and efficacy of its use.
