Abstract
INTRODUCTION Time-To-OR is a critical process measure for trauma performance. However, this measure has not consistently demonstrated improvement in outcome. STUDY DESIGN Using TQIP, we identified facilities by 75th percentile time-to-OR to categorize slow, average, and fast hospitals. Using a GEE model, we calculated odds of mortality for all penetrating abdominal trauma patients, firearm injuries only, and patients with major complication by facility speed. We additionally estimated odds of mortality at the patient level. RESULTS Odds of mortality for patients at slow facilities was 1.095; 95% CI: 0.746, 1.608; p = 0.64 compared to average. Fast facility OR = 0.941; 95% CI: 0.780, 1.133; p = 0.52. At the patient-level each additional minute of time-to-OR was associated with 1.5% decreased odds of in-hospital mortality (OR 0.985; 95% CI:0.981, 0.989; p < 0.001). For firearm-only patients, facility speed was not associated with odds of in-hospital mortality (p-value = 0.61). Person-level time-to-OR was associated with 1.8% decreased odds of in-hospital mortality (OR 0.982; 95% CI: 0.977, 0.987; p < 0.001) with each additional minute of time-to-OR. Similarly, failure-to-rescue analysis showed no difference in in-hospital mortality at the patient level (p = 0.62) and 0.4% decreased odds of in-hospital mortality with each additional minute of time-to-OR at the patient level (OR 0.996; 95% CI: 0.993, 0.999; p = 0.004). CONCLUSION Despite the use of time-to-OR as a metric of trauma performance, there is little evidence for improvement in mortality or complication rate with improved time-to-OR at the facility or patient level. Performance metrics for trauma should be developed that more appropriately approximate patient outcome.

Abstract
The recent prevalence of deep neural networks has led semantic segmentation networks to achieve human-level performance in the medical field, provided they are given sufficient training data. However, these networks often fail to generalize when tasked with creating semantic maps for out-of-distribution images, necessitating re-training on new distributions. This labor-intensive process requires expert knowledge for generating training labels. In the medical field, distribution shifts can naturally occur due to the choice of imaging devices, such as MRI or CT scanners. To mitigate the need for labeling images in a target domain after successful model training in a fully annotated source domain with a different data distribution, unsupervised domain adaptation (UDA) can be employed. Most UDA approaches ensure target generalization by generating a shared source/target latent feature space, allowing a source-trained classifier to maintain performance in the target domain. However, such approaches necessitate joint source and target data access, potentially leading to privacy leaks with respect to patient information. We propose a UDA algorithm for medical image segmentation that does not require access to source data during adaptation, thereby preserving patient data privacy. Our method relies on approximating the source latent features at the time of adaptation and creates a joint source/target embedding space by minimizing a distributional distance metric based on optimal transport. We demonstrate that our approach is competitive with recent UDA medical segmentation works, even with the added requirement of privacy. 1.

Abstract
INTRODUCTION Abdominal wall hernias are a frequent cause of abdominal pain-related emergency department visits. Our study aimed to establish the connection between lactate levels and patient outcomes in those with abdominal pain due to abdominal wall hernias. MATERIALS AND METHODS Our research followed a retrospective, observational, and descriptive approach and two center. We included patients who visited the emergency department for abdominal pain and were confirmed to have abdominal wall hernias through ultrasound. RESULTS We enrolled 493 patients meeting the criteria. Median age was 65 years, with 54% (n = 266) being male. Regarding outcomes, 40.5% (n = 200) were hospitalized, 27.7% (n = 137) underwent surgery, and 7.9% (n = 39) underwent bowel resection. Mortality rate during hernia-related hospital admission was 0.6% (n = 3). For hospitalized patients, there were significant differences in white blood cell count, neutrophil count and percentage, platelet count, lymphocyte count, and percentage (p < 0.05). Patients undergoing resection showed significant differences in neutrophil count, neutrophil percentage, lymphocyte count, and lymphocyte percentage (p < 0.05). Lactate levels were statistically significant in all patient groups requiring hospitalization, surgery, and resection (p < 0.05). Sensitivity and specificity of lactate test results indicated in patients undergoing bowel resection, lactate values ≥1.96 mmol/L had a specificity of 64%, sensitivity of 71%, and a negative predictive value of 96% (p < 0.05). CONCLUSION Low lactate levels in patients presenting to the emergency department with abdominal pain caused by abdominal wall hernias have a high negative predictive value for excluding strangulation and the need for bowel resection. Therefore, we recommend the use of lactate as an additional diagnostic tool in emergency department presentations related to abdominal wall hernias.

Abstract
PURPOSE Spigelian hernias arise at the linear semilunaris and account for approximately 1-2% of abdominal hernias. The aetiology is due to a defect of the aponeurosis of the transverse abdominis and when discovered, management is surgical intervention. The aim of this study was to observe operative outcomes for open and minimally invasive repair. METHODS A retrospective chart review was conducted at two hospitals in Townsville, The Townsville University Hospital and The Mater Private Hospital over a 10-year period (2010 to 2020). A surgical database search (ORMIS & IEMR) was performed at both locations using key search terms, including "spigelian hernia", "laparoscopic", "open". Descriptive statistics were utilised to analyse patient factors and operative outcomes in the public and private setting. RESULTS 43 cases of Spigelian hernias (25 female, 18 male) were reported over the study period. The average age was 66. There were 36 elective cases and 7 emergency cases. A laparoscopic approach was the preferred method of repair, occurring in 74% of cases. Of these cases, the predominant hernial content was fat only. 65% of cases had a history of prior abdominal surgery unrelated to the "Spigelian belt" location. Complications occurred in 19% of cases. Other variables, such as ethnicity, smoking status, defect size, predisposing factors and recurrence rate, were analysed and did not yield statistical significance. CONCLUSION Although a small sample size, the data suggest there is no statistically significant difference between operative outcomes, complication rate and predisposing factors between open and minimally invasive case groups.

Abstract
Successful endovascular aneurysm repair can be achieved with favorable aortic and iliac arterial anatomies. However, patients with challenging iliac anatomy, such as stenotic, calcified, tortuous arteries, or concomitant iliac artery aneurysms, are commonly encountered. Such a hostile iliac anatomy increases the risk of intraprocedural complications and worsens long-term outcomes. This review addresses various technical options for treating patients with a hostile iliac anatomy, including innovative endovascular solutions, physician-modified endografts, and hybrid procedures. These considerations demonstrate the wide scope of therapies that may be offered to patients with an unfavorable iliac anatomy.

Abstract
OBJECTIVE The investigation of the role of preoperative conization in cervical cancer aiming to explore its potential clinical significance. DATA SOURCES Cochrane Library, Embase, PubMed, and Web of Science, up to April 28, 2023. METHODS OF STUDY SELECTION (1) Observational cohort studies, (2) studies comparing radical hysterectomy with preoperative conization (CO) vs radical hysterectomy without preoperative conization (NCO) in patients with early-stage cervical cancer, and (3) studies comparing disease-free survival outcomes. TABULATION, INTEGRATION, AND RESULTS Two reviewers independently extracted the data and assessed the quality of the studies. The meta-analysis used combined hazard ratios along with their corresponding 95% confidence intervals to compare CO and NCO. We conducted a Bayesian network meta-analysis using Markov chain Monte Carlo methods to compare minimally invasive CO, open CO, minimally invasive NCO, and open NCO. Our study included 15 retrospective trials, 10 of which were used to traditional pairwise meta-analysis and 8 for network meta-analysis. The NCO group exhibited a notably higher probability of cancer recurrence than the CO group (hazard ratio, 0.52; 95% confidence interval, 0.41-0.65). In the network meta-analysis, minimally invasive NCO showed the worst survival outcome. CONCLUSION Preoperative conization seems to be a protective factor in decreasing recurrence risk, assisting clinicians in predicting survival outcomes for patients with early-stage cervical cancer. It may potentially aid in selecting suitable candidates for minimally invasive surgery in clinical practice.

Abstract
Bowel obstruction (BO) in children has a wide differential diagnosis, ranging from non-urgent conditions to surgical emergencies. Abdominal radiographs are most often used as the first imaging modality for the evaluation of obstruction. However, for some indications, ultrasound can be the primary imaging modality. Therefore, it is incumbent on radiologists to recognize the types of bowel obstruction that can be recognized with US. Key sonographic features of BO include differential dilation of bowel loops, bowel wall thickening, and free fluid. "Do Not Miss" findings that indicate need for emergent treatment include volvulus, pneumoperitoneum, and/or signs of ischemia (bowel wall thinning and/or absent perfusion). The aim of this pictorial essay is to provide guidance on the sonographic technique and findings that enable identification of BO on US. Examples of neonatal BO on US, including common and less frequently encountered etiologies, are illustrated in this pictorial essay.

Abstract
Abdominal pregnancy is a rare form of ectopic pregnancy where implantation and development of the egg take place in the peritoneal cavity outside the tubo-uterine mucosa, in contact with intestinal loops. Diagnosis is most often difficult. We report the case of a 32-year-old woman (gravida 1, para 1), with a history of PCOS, diagnosed with abdominal pregnancy at 20 weeks of amenorrhea complicated by acute intestinal obstruction. Diagnosis was confirmed by abdomino-pelvic scan. Surgery was performed with the patient under general anesthesia. She presented a macerated fetus with an infiltration of the placenta causing a perforation of the sigmoid colon and uterus. Hartmann's procedure was performed and the perforation of the uterus was sutured. Abdominal pregnancy remains a rare variety of ectopic pregnancy. Preoperative diagnosis is difficult due to the presence of a variety of non-specific symptoms. This type of ectopic pregnancy remains challenging for gynecologists and radiologists.

Abstract
INTRODUCTION The image quality of continuously acquired free-breathing Dynamic Contrast-Enhanced (DCE) golden-angle radial Magnetic Resonance Imaging (MRI) of abdomen suffers from motion artifacts and motion-related blurring. We propose a scheme by minimizing patients' motion status from breathing as well as optimizing the acquiring parameters to improve image quality and diagnostic performance of DCE-MRI with Golden-Angle Radial Sparse Parallel (GRASP) sequence of abdomen. METHODS The optimization scheme follows two principles: (1) reduce the impact on images from unpredictable and irregulate motions during examination and (2) adjust the sequence parameters to increase the number of radial views in each partition. For the assessment of image quality, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), the severity of radial artifact, the degree of image sharpness, and a visual scoring of image quality with a 5-point scale were assessed. RESULTS A total of 64 patients were included in this study before (16 men, 14 women, age: 54.9 ± 17.0) and after (18 men, 16 women, age: 58.6 ± 12.6) the optimization scheme was performed. The results showed that the SNR values of right and left lobe of liver in both plain phase and arterial phase were significantly increased (All P < 0.001) after the GRASP sequence been optimized. Significant improvements in CNR values were observed in the arterial phase (All P < 0.05). The significant differences in scores at each phase for visual scoring of image quality, noise of the right and left lobe of liver, radial artifact, and sharpness indicating that the image quality was significantly improved after the optimization (All P < 0.001). CONCLUSION Our study demonstrated that the optimized scheme significantly improved the image quality of liver DCE-MRI with GRASP sequence both in plain and arterial phases. The optimized scheme of GRASP sequence could be a superior alternative to conventional approach for the assessment of liver.

Abstract
Contemporary whole-body low-field MRI scanners (< 1 T) present new and exciting opportunities for improved body imaging. The fundamental reason is that the reduced off-resonance and reduced SAR provide substantially increased flexibility in the design of MRI pulse sequences. Promising body applications include lung parenchyma imaging, imaging adjacent to metallic implants, cardiac imaging, and dynamic imaging in general. The lower cost of such systems may make MRI favorable for screening high-risk populations and population health research, and the more open configurations allowed may prove favorable for obese subjects and for pregnant women. This article summarizes promising body applications for contemporary whole-body low-field MRI systems, with a focus on new platforms developed within the past 5 years. This is an active area of research, and one can expect many improvements as MRI physicists fully explore the landscape of pulse sequences that are feasible, and as clinicians apply these to patient populations.

Abstract
Purpose Physician-modified endovascular stent grafts (PMEG) are a good treatment option for complex abdominal aortic aneurysms (AAAs), especially in high-risk patients not amenable to open repair, and when commercial fenestrated devices are not available. We report our single-center experience with PMEG for the treatment of complex AAAs. Methods We retrospectively reviewed patients who underwent PMEG repair for AAA from November 2016 to September 2020 at our institution. Demographic data, anatomic characteristics, perioperative and postoperative outcomes, major adverse events, and 30-day mortality were analyzed. Results We identified 12 patients who underwent PMEG for complex AAA. The mean age was 74 years and the mean maximal AAA diameter was 58.1 mm. Indications for treatment included 4 impending or contained ruptures, 2 mycotic aneurysms, and 6 symptomatic cases. The technical success rate was 91.7%. Aneurysm sac regression was observed in 7 patients (58.3%), including 2 cases of complete regression. There was 1 aneurysm-related mortality at 3 months due to mycotic aneurysm. Also, there was 1 postoperative complication case of transient renal failure requiring temporary dialysis. At 1 year, there was 1 branch occlusion from the initial failed cannulation case and 2 type 1A endoleaks, and there was 1 case of open explantation. Conclusion PMEG showed a low technical failure rate and acceptable midterm stent durability and sac stability, comparable to conventional endovascular aneurysm repair. Despite the small number of cases, there was a tendency for a high sac regression rate, although longer follow-up is needed.

Abstract
BACKGROUND After approval for clinical use in 2017 early investigations of ultra-high-field abdominal magnetic resonance imaging (MRI) have demonstrated the feasibility as well as diagnostic capabilities of liver, kidney, and prostate MRI at 7-Tesla. However, the elevation of the field strength to 7-Tesla not only brought advantages to abdominal MRI but also presented considerable challenges and drawbacks, primarily stemming from heightened artifacts and limitations in Specific Absorption Rate, etc. Furthermore, evidence in the literature is relatively scarce concerning human studies in comparison to phantom/animal studies which necessitates an investigation into the evidence so far in humans and summarizing all relevant evidence. AIM To offer a comprehensive overview of current literature on clinical abdominal 7T MRI that emphasizes current trends, details relevant challenges, and provides a concise set of potential solutions. METHODS This systematic review adheres to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A PubMed search, utilizing Medical Subject Headings terms such as "7-Tesla" and organ-specific terms, was conducted for articles published between January 1, 1985, and July 25, 2023. Eligibility criteria included studies exploring 7T MRI for imaging human abdominal organs, encompassing various study types (in-vivo/ex-vivo, method development, reviews/meta-analyses). Exclusion criteria involved animal studies and those lacking extractable data. Study selection involved initial identification via title/abstract, followed by a full-text review by two researchers, with discrepancies resolved through discussion. Data extraction covered publication details, study design, population, sample size, 7T MRI protocol, image characteristics, endpoints, and conclusions. RESULTS The systematic review included a total of 21 studies. The distribution of clinical 7T abdominal imaging studies revealed a predominant focus on the prostate (n = 8), followed by the kidney (n = 6) and the hepatobiliary system (n = 5). Studies on these organs, and in the pancreas, demonstrated clear advantages at 7T. However, small bowel studies showed no significant improvements compared to traditional MRI at 1.5T. The majority of studies evaluated originated from Germany (n = 10), followed by the Netherlands (n = 5), the United States (n = 5), Austria (n = 2), the United Kingdom (n = 1), and Italy (n = 1). CONCLUSION Further increase of abdominal clinical MRI field strength to 7T demonstrated high imaging potential, yet also limitations mainly due to the inhomogeneous radiofrequency (RF) excitation field relative to lower field strengths. Hence, further optimization of dedicated RF coil elements and pulse sequences are expected to better optimize clinical imaging at high magnetic field strength.

Abstract
OBJECTIVES To explore the association between computed tomography (CT)-measured sex-specific abdominal adipose tissue and the pathological grade of clear cell renal cell carcinoma (ccRCC). METHODS This retrospective study comprised 560 patients (394 males and 166 females) with pathologically proven ccRCC (467 low- and 93 high-grade). Abdominal CT images were used to assess the adipose tissue in the subcutaneous, visceral, and intermuscular regions. Subcutaneous fat index (SFI), visceral fat index (VFI), intermuscular fat index (IFI), total fat index (TFI), and relative visceral adipose tissue (rVAT) were calculated. Univariate and multivariate logistic regression analyses were performed according to sex to identify the associations between fat-related parameters and pathological grade. RESULTS IFI was significantly higher in high-grade ccRCC patients than in low-grade patients for both men and women. For male patients with high-grade tumors, the SFI, VFI, TFI, and rVAT were significantly lower, but not for female patients. In both univariate and multivariate studies, the IFI continued to be a reliable and independent predictor of high-grade ccRCC, regardless of sex. CONCLUSIONS Intermuscular fat index proved to be a valuable biomarker for the pathological grade of ccRCC and could be used as a reliable independent predictor of high-grade ccRCC for both males and females. CRITICAL RELEVANCE STATEMENT Sex-specific fat adipose tissue can be used as a new biomarker to provide a new dimension for renal tumor-related research and may provide new perspectives for personalized tumor management decision-making approaches. KEY POINTS • There are sex differences in distribution of subcutaneous fat and visceral fat. • The SFI, VFI, TFI, and rVAT were significantly lower in high-grade ccRCC male patients, but not for female patients. • Intermuscular fat index can be used as a reliable independent predictor of high-grade ccRCC for both males and females.

Abstract
OBJECTIVE The need for open surgical conversion (OSC) after failed endovascular aortic aneurysm repair (EVAR) persists, despite expanding endovascular options for secondary intervention. The VASCUNExplanT project collected international data to identify risk factors for failed EVAR, as well as OSC outcomes. This retrospective cross sectional study analysed data after OSC for failed EVAR from the VASCUNET international collaboration. METHODS VASCUNET queried registries from its 28 member countries, and 17 collaborated with data from patients who underwent OSC (2005 - 2020). Any OSC for infection was excluded. Data included demographics, EVAR, and OSC procedural details, as well as post-operative mortality and complication rates. RESULTS There were 348 OSC patients from 17 centres, of whom 33 (9.4%) were women. There were 130 (37.4%) devices originally deployed outside of instructions for use. The most common indication for OSC was endoleak (n = 143, 41.1%); ruptures accounted for 17.2% of cases. The median time from EVAR to OSC was 48.6 months [IQR 29.7, 71.6]; median abdominal aortic aneurysm diameter at OSC was 70.5 mm [IQR 61, 82]. A total of 160 (45.6%) patients underwent one or more re-interventions prior to OSC, while 63 patients (18.1%) underwent more than one re-intervention (range 1 - 5). Overall, the 30 day mortality rate post-OSC was 11.8% (n = 41), 11.1% for men and 18.2% for women (p = .23). The 30 day mortality rate was 6.1% for elective cases, and 28.3% for ruptures (p < .0001). The predicted 90 day survival for the entire cohort was 88.3% (95% CI 84.3 - 91.3). Multivariable analysis revealed rupture (OR 4.23; 95% CI 2.05 - 8.75; p < .0001) and total graft explantation (OR 2.10; 95% CI 1.02 - 4.34; p = .04) as the only statistically significant predictive factors for 30 day death. CONCLUSION This multicentre analysis of patients who underwent OSC shows that, despite varying case mix and operative techniques, OSC is feasible but associated with significant morbidity and mortality rates, particularly when performed for rupture.

Abstract
Endometriosis is defined as the presence of functioning endometrial tissue outside the uterine cavity. Abdominal wall or cutaneous endometriomas are quite uncommon with an incidence of less than 1%. Abdominal wall endometrioma can occur in a previous surgical scar, commonly following obstetrical and gynecological surgeries. Cutaneous endometriosis is difficult to diagnose because of its nonspecific symptoms and is often confused with other dermatological and surgical diseases thereby delaying the diagnosis and management. We are reporting a case of scar endometriosis at the site of previous cesarean scar involving the rectus sheath. The pathogenesis, diagnosis, and treatment of this rare condition are being discussed. Awareness of the clinical features and presentation of this rare condition is essential for timely diagnosis and management.

Abstract
BACKGROUND Blunt abdominal trauma has rarely been reported as a cause of acute appendicitis in the literature. However, the coexistence of the two conditions can cause issues for the patient. We present here a systematic review of cases of traumatic appendicitis as well as our own experience with a 12-year-old male patient. CASE SUMMARY A 12-year-old male was admitted 3 d after abdominal trauma, experiencing peritoneal syndrome. A pelvic formation was discovered during abdominal ultrasound, and surgical exploration revealed a perforated appendix. A literature review was conducted applying the keywords "appendicitis," "abdominal," and "trauma" to the PubMed, Embase, and Medline databases. Our initial search included 529 papers published between 1991 and 2022, of which 33 papers were finally included. They revealed 51 reported cases. The trauma mechanisms included road traffic accidents, falls, assaults, ball accidents, a horse kick, and a colonoscopy. Eight patients underwent surgical exploration with no prior radiological investigation, and twenty-six patients underwent an initial radiological examination. All reports indicated a perforated appendix. CONCLUSION Acute traumatic appendicitis represents a diagnostic quandary that can be misdiagnosed resulting in significant morbidity and potential mortality. A high level of suspicion combined with radiological examination may aid in the diagnosis and treatment of this condition.

Abstract
OBJECTIVE A lower elective repair rate among women with abdominal aortic aneurysms (AAAs) has been a consistent finding. Reasons behind this gender gap have not been thoroughly outlined. METHODS This was a retrospective multicenter cohort study (ClinicalTrials.gov: NCT05346289) at three European vascular centers in Sweden, Austria and Norway. Patients in surveillance with AAAs were consecutively identified starting from January 1, 2014, until reaching a total sample size of 200 women and 200 men. All individuals were followed for 7 years through medical records. Final treatment distributions and the proportion of "truly untreated" (surgically untreated despite reaching guideline-directed thresholds: 50 mm for women and 55 mm for men) were determined. In a complementary analysis, a universal 55-mm threshold was used. Gender-specific primary reasons behind untreated statuses were clarified. Eligibility for endovascular repair among the truly untreated was assessed in a structured computed tomography analysis. RESULTS Women and men had similar median diameters at inclusion (46 mm; P = .54) and at treatment decisions (55 mm; P = .36). After 7 years, the repair rate was lower among women (47% vs 57%). More women were truly untreated (26% vs 8%; P < .001) despite similar mean ages as for male counterparts (79.3 years; P = .16). With the 55-mm threshold, 16% women still classified as truly untreated. Similar reasons for nonintervention were captured for women and men (50% due to comorbidities alone, 36% morphology and comorbidity). The endovascular repair imaging analysis revealed no gender differences. Among truly untreated women, ruptures were common (18%), and mortality was high (86%). CONCLUSIONS Surgical AAA management differed between women and men. Women could be underserved in terms of elective repairs: one in every four women was untreated with over-the-threshold AAAs. The lack of obvious gender differences in eligibility analyses could imply unmeasured discrepancies (eg, in disease extent or patient frailty).

Abstract
OBJECTIVES The aim of the present study was to examine the dose-response relationship between trunk tissue composition and prevalence of metabolic syndrome (MetS) in middle-aged Japanese men. METHODS The 1026 men (between 35 and 59 y of age) who participated in the present study were divided into two groups: those with metabolic syndrome (MetS) and those without (non-MetS). Intramuscular adipose tissue (IntraMAT) content and the cross-sectional areas (CSAs) of visceral adipose tissue and skeletal muscle tissue were calculated using low-dose computed tomography images acquired at the level of the third lumbar vertebra. Height, body mass, body fat, waist circumference, the presence of MetS, and lifestyle habits were also assessed. RESULTS IntraMAT content was significantly higher in MetS than in non-MetS men. A 10% increase in IntraMAT content correlated with the prevalence of MetS (odds ratio, 4.197; 95% confidence interval, 3.108-7.088; P < 0.001), even after adjustments for age, height, adjusted skeletal muscle CSA, sleeping time, alcohol consumption, exercise habit, and cigarette smoking. Skeletal muscle CSA did not correlate with the prevalence of MetS after adjustments for IntraMAT content and other cofactors. CONCLUSIONS Increase in IntraMAT content, not in skeletal muscle CSA, significantly correlated with the prevalence of MetS. These results suggest that countermeasures against the accumulation of trunk IntraMAT effectively prevent MetS in middle-aged Japanese men.

Abstract
Four-dimensional flow MRI is a powerful phase contrast technique used for assessing three-dimensional (3D) blood flow dynamics. By acquiring a time-resolved velocity field, it enables flexible retrospective analysis of blood flow that can include qualitative 3D visualization of complex flow patterns, comprehensive assessment of multiple vessels, reliable placement of analysis planes, and calculation of advanced hemodynamic parameters. This technique provides several advantages over routine two-dimensional flow imaging techniques, allowing it to become part of clinical practice at major academic medical centers. In this review, we present the current state-of-the-art cardiovascular, neurovascular, and abdominal applications.

Abstract
Despite advances in diagnosis and treatment in recent years, tuberculosis (TB) remains a global health concern. Children are amongst the most vulnerable groups affected by this disease. Although TB primarily involves the lungs and mediastinal lymph nodes, it can affect virtually any organ system of the body. Along with clinical history combined with physical examination and laboratory tests, various medical imaging tools help establish the diagnosis. Medical imaging tests are also helpful for follow-up during therapy, to assess complications and exclude other underlying pathologies. This article aims to discuss the utility, strengths and limitations of medical imaging tools in the evaluation of suspected extrathoracic TB in the pediatric population. Imaging recommendations for the diagnosis will be presented along with practical and evidence-based imaging algorithms to serve as a guide for both radiologists and clinicians.

Abstract
Intra-abdominal infections (IAI) are among the most common global healthcare challenges and they are usually precipitated by disruption to the gastrointestinal (GI) tract. Their successful management typically requires intensive resource utilization, and despite the best therapies, morbidity and mortality remain high. One of the main issues required to appropriately treat IAI that differs from the other etiologies of sepsis is the frequent requirement to provide physical source control. Fortunately, dramatic advances have been made in this aspect of treatment. Historically, source control was left to surgeons only. With new technologies non-surgical less invasive interventional procedures have been introduced. Alternatively, in addition to formal surgery open abdomen techniques have long been proposed as aiding source control in severe intra-abdominal sepsis. It is ironic that while a lack or even delay regarding source control clearly associates with death, it is a concept that remains poorly described. For example, no conclusive definition of source control technique or even adequacy has been universally accepted. Practically, source control involves a complex definition encompassing several factors including the causative event, source of infection bacteria, local bacterial flora, patient condition, and his/her eventual comorbidities. With greater understanding of the systemic pathobiology of sepsis and the profound implications of the human microbiome, adequate source control is no longer only a surgical issue but one that requires a multidisciplinary, multimodality approach. Thus, while any breach in the GI tract must be controlled, source control should also attempt to control the generation and propagation of the systemic biomediators and dysbiotic influences on the microbiome that perpetuate multi-system organ failure and death. Given these increased complexities, the present paper represents the current opinions and recommendations for future research of the World Society of Emergency Surgery, of the Global Alliance for Infections in Surgery of Surgical Infection Society Europe and Surgical Infection Society America regarding the concepts and operational adequacy of source control in intra-abdominal infections.

Abstract
Abdominal sonography is currently a routine procedure in the evaluation of colic in the horse. This imaging technique is used in both the assessment of the horse presented in the emergency setting with acute colic and the assessment of the horse presented for chronic or recurrent colic in the nonemergency setting. Sonography for colic evaluation is used by specialists in different disciplines and by general practitioners in the ambulatory and hospital settings. In this review, we will focus on indications and clinical interpretation of findings as well as recent developments in abdominal sonography.

Abstract
BACKGROUND Abdominal wall desmoid-type fibromatoses (AWDF) are occasionally encountered in clinical work, but related CT reports are rare, and most cases were misdiagnosed as malignant tumors. OBJECTIVE We aimed to determine the diagnostic value of multislice computed tomography (MSCT) in relation to the clinical diagnosis of AWDF. METHODS The medical records of 14 patients whose pathology results provided initial confirmation of AWDF were reviewed, and data describing their clinical characteristics, tumors' MSCT characteristics, and the condition of the surrounding tissues were analyzed and summarized retrospectively. Intraobserver and interobserver reproducibilities were evaluated. RESULTS AWDF tended to occur in women of childbearing age (24-32 years). They occurred more frequently during the first year following pregnancy. The mean disease duration was 5.64 ± 3.78 months. All isolated tumors were growing along the musculoaponeurotic layer, and their maximum diameters were between 32 and 76 mm. Tumors' capsules were incomplete, and although the tumors infiltrated the surrounding muscles, the surrounding fat tissue and vessels were not infiltrated. None of the patients' tumors showed cystic degeneration, calcification, necrosis, or peritumoral edema. The tumors had slightly lower densities on the pre-contrast enhancement scans and mild-to-moderate enhancement after contrast enhancement. All tumors contained ribbon-like structures, and approximately 65% of the tumors encircled vascular structures. CONCLUSION Dual-phase contrast-enhanced MSCT scans were associated with a high level of diagnostic efficacy for AWDF. The abdominal wall masses grew along the musculoaponeurotic layer, which, together with the ribbon-like structures within the tumors, should prompt clinicians to consider the presence of AWDF.

Abstract
BACKGROUND We assessed the effect of race and ethnicity on presentation severity and postoperative outcomes in those with abdominal aortic aneurysms (AAAs), carotid artery stenosis (CAS), peripheral arterial disease (PAD), and type B aortic dissection (TBAD). METHODS MEDLINE, Embase, and Cochrane Central Register of Controlled Trials from inception until December 2020. Two reviewers independently selected randomized controlled trials and observational studies reporting race and/or ethnicity and presentation severity and/or postoperative outcomes for adult patients who had undergone major vascular procedures. They independently extracted the study data and assessed the risk of bias using the Newcastle-Ottawa scale. The meta-analysis used random effects models to derive the odds ratios (ORs) and risk ratios (RRs) and their corresponding 95% confidence intervals (CIs). The primary outcome was presentation severity stratified by the proportion of patients with advanced disease, including ruptured vs nonruptured AAA, symptomatic vs asymptomatic CAS, chronic limb-threatening ischemia vs claudication, and complicated vs uncomplicated TBAD. The secondary outcomes included postoperative all-cause mortality and disease-specific outcomes. RESULTS A total of 81 studies met the inclusion criteria. Black (OR, 4.18; 95% CI, 1.31-13.26), Hispanic (OR, 2.01; 95% CI, 1.85-2.19), and Indigenous (OR, 1.97; 95% CI, 1.39-2.80) patients were more likely to present with ruptured AAAs than were White patients. Black and Hispanic patients had had higher symptomatic CAS (Black: OR, 1.20; 95% CI, 1.04-1.38; Hispanic: OR, 1.32; 95% CI, 1.20-1.45) and chronic limb-threatening ischemia (Black: OR, 1.67; 95% CI, 1.14-2.43; Hispanic: OR, 1.73; 95% CI 1.13-2.65) presentation rates. No study had evaluated the effect of race or ethnicity on complicated TBAD. All-cause mortality was higher for Black (RR, 1.23; 95% CI, 1.01-1.51), Hispanic (RR, 1.90; 95% CI, 1.57-2.31), and Indigenous (RR, 1.24; 95% CI, 1.12-1.37) patients after AAA repair. Postoperatively, Black (RR, 1.54; 95% CI, 1.19-2.00) and Hispanic (RR, 1.54; 95% CI, 1.31-1.81) patients were associated with stroke/transient ischemic attack after carotid revascularization and lower extremity amputation (RR, 1.90; 95% CI, 1.76-2.06; and RR, 1.69; 95% CI, 1.48-1.94, respectively). CONCLUSIONS Certain visible minorities were associated with higher morbidity and mortality across various vascular surgery presentations. Further research to understand the underpinnings is required.

Abstract
Formulating clear guidelines for the most reliable treatment methods for complete rectal prolapse appears challenging. The authors designed this study to compare the results according to the approaches for female complete rectal prolapse and to suggest a more effective method. The transanal and abdominal groups showed differences in operating time, hospital stay, and recurrence rate. However, both groups demonstrated improvement in postoperative functional evaluation. PURPOSE There is a wide variety of surgical methods to treat rectal prolapse; however, to date, no clear agreement exists regarding the most effective surgical method. This study was designed to compare the results according to the surgical approach for complete rectal prolapse in women. METHODS This study was conducted from March 2016 to February 2021 on female patients with rectal prolapse who underwent surgery. First, all patients were classified into mucosal and complete layer groups to confirm the difference in results between the two groups, and only complete layer prolapse patients were divided into transanal and abdominal approaches to compare parameters and functional outcomes in each group. RESULTS A total of 180 patients were included, with an average age of 71.7 years and 102 complete prolapses. The complete layer group was found to have more abdominal access, longer operating time, and higher recurrence rates compared to the mucosal layer group. (p<0.001) When targeting only the complete layer patients, there were 65 patients with the transanal and 37 with the abdominal (laparoscopic) approaches. The abdominal approach group had a longer operating time and hospital stay (p<0.001, respectively) and lower recurrence rate than the transanal group (transanal vs. abdominal, 38% vs. 10.8%, p=0.003), while the Wexner constipation and incontinence scores showed improved results in both groups. CONCLUSION Although operating time and hospitalization period were shorter in the transanal group, laparoscopic abdominal surgery is a procedure that can reduce the recurrent rate for complete rectal prolapse.

Abstract
BACKGROUND The treatment of complicated intra-abdominal infections remains a challenge. Both optimal medical and surgical therapy (i.e., source control) are needed to achieve low mortality and morbidity. The objective of this systematic review and meta-analysis is to determine the impact of carbapenem antibiotic therapy compared to other antibiotics in complicated intra-abdominal infections (secondary peritonitis) with an emphasis on mortality and postoperative complications. METHODS A systematic literature search from PubMed/Medline and Web of Science databases was carried out. The last search was conducted in August 2022. PRISMA guidelines were followed. Pre-defined outcomes were mortality, treatment success, treatment failure, and adverse events. RESULTS Ten randomized controlled trials, published from 1983 to 2013 with a total of 2377 patients (1255 patients in the carbapenem antibiotics group and 1122 in the control group), were identified. A meta-analysis comparing patients undergoing carbapenem antibiotic therapy and patients receiving other antibiotics was performed. No significant difference regarding mortality (OR 1.19, 95% CI [0.79; 1.82], p = 0.40), treatment success (OR 1.17, 95% CI [0.72; 1.91], p = 0.53), and treatment failure (OR 0.84, 95% CI [0.48; 1.45], p = 0.52) was observed. Carbapenem therapy was associated with fewer adverse events compared to therapy with other antibiotics (OR 0.79, 95% CI [0.65; 0.97], p = 0.022). CONCLUSION There is currently no evidence that carbapenem antibiotics are superior in terms of mortality, and success or failure for the treatment of complicated intra-abdominal infections (secondary peritonitis). The rate of adverse events is lower under carbapenem therapy compared to control antibiotics. TRIAL REGISTRATION PROSPERO 2018 CRD42018108854.

Abstract
INTRODUCTION Care bundles were found to improve postoperative outcomes in elective surgery. However, in major emergency general surgery studies show a divergent impact on mortality and length of stay. This meta-analysis aimed to evaluate associations between care bundles and mortality, complications, and length of stay when applied in major emergency general surgery. METHODS A systematic literature search in PubMed and Embase was performed on the May 1, 2021. Only comparative studies on care bundles in major emergency general surgery were included. Meta-analysis and trial sequential analysis were performed on 30-d mortality. We undertook a narrative approach of long-term mortality, complications, and length of stay. RESULTS Meta-analysis of 13 studies with 35,771 patients demonstrated that care bundles in emergency surgery were not associated with a significant reduction in odds of 30-d mortality (odds ratio = 0.8, 95% confidence interval 0.62-1.03). Trial sequential analysis confirmed that the meta-analysis was underpowered with a minimum of 78,901 patients required for firm conclusions. Seven studies reported complication rates whereof six reported lower complication rates using care bundles. CONCLUSIONS Care bundles were reported to decrease postoperative complications in five out of seven studies and seven out of 11 studies reported a shortening in length of stay.

Abstract
INTRODUCTION Since FDA approval for contrast-enhanced ultrasound (CEUS), clinical applications have increased to include diagnostic imaging of hepatic, renal, and other abdominal lesions. The modality has also demonstrated utility in certain image-guided procedures. Intravascular ultrasound contrast agents use microbubbles to improve visibility of solid tumors. Lesions not well seen on grayscale or Doppler ultrasound may become amenable to CEUS-guided biopsy or ablation. MATERIALS AND METHODS This pictorial essay provides eleven examples to illustrate the current use of CEUS in a variety of abdominal image-guided procedures. Hepatic, renal, peritoneal, and soft tissue cases are presented. CONCLUSION CEUS can improve visualization and targeting in abdominal image-guided procedures, without nephrotoxicity or radiation exposure.

Abstract
OBJECTIVE To compare rates of mortality, rupture, and secondary intervention following endovascular repair (EVAR) of intact abdominal aortic aneurysms (AAA) using contemporary endograft devices from three major manufacturers. METHODS This was a retrospective cohort study using linked clinical registry (Australasian Vascular Audit) and all payer administrative data. Patients undergoing EVAR for intact AAA between 2010 and 2019 in New South Wales, Australia were identified. Rates of all cause death, secondary rupture, and secondary intervention (subsequent aneurysm repair; other secondary aortic intervention) were compared for patients treated with Cook, Medtronic, and Gore standard devices. Inverse probability of treatment weighted proportional hazards and competing risk regression were used to adjust for patient, clinical, and aneurysm characteristics, using Cook as the referent device. RESULTS This study identified 2 874 eligible EVAR patients, with a median follow up of 4.1 (maximum 9.5) years. Mortality rates were similar for patients receiving different devices (ranging between 7.0 and 7.3 per 100 person years). There was no statistically significant difference between devices in secondary rupture rates, which ranged between 0.4 and 0.5 per 100 person years. Patients receiving Medtronic and Gore devices tended to have higher crude rates of subsequent aneurysm repair (1.5 per 100 person years) than patients receiving Cook devices (0.8 per 100 person years). This finding remained in the adjusted analysis, but was only statistically significant for Medtronic devices (HR 1.57, 95% CI 1.02 - 2.47; HR 1.73, 95% CI 0.94 - 3.18, respectively). CONCLUSION Major endograft devices have similar overall long term safety profiles. However, there may be differences in rates of secondary intervention for some devices. This may reflect endograft durability, or patient selection for different devices based on aneurysm anatomy. Continuous comparative assessments are needed to guide evidence for treatment decisions across the range of available devices.

Abstract
BACKGROUND The ideal approach to inguinal hernia repair (IHR) after prior pelvic or low abdominal surgery is not agreed upon. We compared safety and outcomes of IHR between open, laparoscopic, and robotic approaches. METHODS This retrospective review of a prospective database analyzed demographic, perioperative, and quality of life data for patients who underwent IHR after pelvic or low abdominal surgery. RESULTS 286 qualifying patients underwent IHR between 2008 and 2020; 119 open, 147 laparoscopic, and 20 robotic. Laparoscopic repair led to faster cessation of narcotics and return to ADLs than open repair (all p <0.05). Post-operative complications, 30-day readmission, recurrences, and quality of life outcomes were equivalent, except less pain at 3-weeks post-op in the minimally invasive groups, p < 0.01. CONCLUSION Minimally invasive IHR after prior pelvic or low abdominal surgery is safe compared to an open approach. Laparoscopic repair provides faster recovery, yet patient satisfaction is equivalent regardless of surgical approach.

Abstract
BACKGROUND B-mode ultrasound is versatile and safe. The sequelae of aortic disorders in children range from stunted growth in hypoplasia to 90% fatality in ruptured aneurysms. Thus, age-based reference values are necessary for early detection of abnormal aortic dimensions. OBJECTIVE To create age-based reference values of paediatric aorta diameters from B-mode ultrasound using the outer-to-outer method. MATERIALS AND METHODS A retrospective review was done of records of peak systolic anteroposterior aortic diameters, obtained during abdominal ultrasound in children ages 2 days to 17 years between January 2016 and December 2019. Cases were grouped into five age groups. RESULTS A total of 643 cases (49% female) were recruited into the study. Only 488 cases (76%) had values for the proximal, mid and distal aorta. The cumulative mean age was 9.5±5.1 years while the mean aortic diameter ranged from 0.3 cm to 1.8 cm. Tables of aortic diameters and reference ranges are presented. There was no significant sex difference. Significant positive correlation was only seen between age and aortic diameters (Pearson's r ranges from 0.66 to 0.91). CONCLUSION An age-based paediatric aortic reference table from B-mode ultrasound using outer-to-outer measurement in a Nigerian population is reported.

Abstract
BACKGROUND The cause of death for patients with an abdominal aortic aneurysm (AAA) can be related to the AAA itself. However, cancer-related mortality could also be a contributing factor. In the present study, we examined the hypothesis that an association exists between AAAs and certain cancers. METHODS Information from 2009 to 2015 was extracted from the Korean National Health Insurance Service database. We included 14,920 participants with a new diagnosis of an AAA. Propensity score matching by age and sex with disease-free patients was used to select the control group of 44,760 participants. The primary end point of the present study was a new diagnosis of various cancers. RESULTS The hazard ratio (HR) for cancer incidence was higher in the AAA group than in the control group for hepatoma, pancreatic cancer, and lung cancer (HR, 1.376, 1.429, and 1.394, respectively). In the case of leukemia, the HR for cancer occurrence was not significantly higher in the AAA group than in the control group. However, when stratified by surgery, the HR was significantly higher for the surgical group (HR, 3.355), especially for endovascular aneurysm repair (HR, 3.864). CONCLUSIONS We found that AAAs are associated with an increased risk of cancer, in particular, hepatoma, pancreatic cancer, and lung cancer, even after adjusting for several comorbidities. Thus, continued follow-up is necessary for patients with an AAA to permit the early detection of the signs and symptoms of cancer.

Abstract
BACKGROUND Research on the peptide phoenixin has increased in recent years and greatly widened the known scope of its functions since its discovery in 2013. Involvement of phoenixin has since been shown in anxiety, food intake, reproduction as well as emotional and immunological stress. To further evaluate its involvement in stress reactions, this study aims to investigate the effects of abdominal surgery, a well-established physical stressor, on the activity of phoenixin-immunoreactive brain nuclei. METHODS Male Sprague-Dawley rats (n = 6/group) were subjected to either an abdominal surgery stress protocol or a sham operation. Animals in the verum group were anesthetized, the abdominal cavity opened and the cecum palpated, followed by closing of the abdomen and recovery. Sham operated animals only received inhalation anesthesia and time for recovery. All animals were subsequently sacrificed and brains processed and evaluated for c-Fos activity as well as phoenixin density. RESULTS Compared to control, abdominal surgery significantly increased c-Fos activity in the paraventricular nucleus (PVN, 6.4-fold, p < 0.001), the medial part of the nucleus of the solitary tract (mNTS, 3.8-fold, p < 0.001), raphe pallidus (RPa, 3.6-fold, p < 0.001), supraoptic nucleus (SON, 3.2-fold, p < 0.001), ventrolateral medulla (VLM, also called A1C1, 3.0-fold, p < 0.001), dorsal motor nucleus of vagus (DMN, 2.9-fold, p < 0.001), locus coeruleus (LC, 1.8-fold, p < 0.01) and Edinger-Westphal nucleus (EW, 1.6-fold, p < 0.05), while not significantly altering c-Fos activity in the amygdala (CeM, 1.3-fold, p > 0.05). Phoenixin immunoreactivity was not significantly affected by abdominal surgery (p > 0.05). CONCLUSION The observed abdominal surgery-related increase in activity in phoenixin immunoreactive nuclei compared to sham surgery controls supports the hypothesis of an involvement of phoenixin in stress reactions. Interestingly, various psychological and physical stressors lead to specific changes in activity and immunoreactivity in phoenixin-containing nuclei, giving rise to a stressor-specific involvement of phoenixin.

Abstract
AIMS/HYPOTHESIS South Asians have a two- to fivefold higher risk of developing type 2 diabetes than those of white European descent. Greater central adiposity and storage of fat in deeper or ectopic depots are potential contributing mechanisms. We collated existing and new data on the amount of subcutaneous (SAT), visceral (VAT) and liver fat in adults of South Asian and white European descent to provide a robust assessment of potential ethnic differences in these factors. METHODS We performed a systematic review of the Embase and PubMed databases from inception to August 2021. Unpublished imaging data were also included. The weighted standardised mean difference (SMD) for each adiposity measure was estimated using random-effects models. The quality of the studies was assessed using the ROBINS-E tool for risk of bias and overall certainty of the evidence was assessed using the GRADE approach. The study was pre-registered with the OSF Registries ( https://osf.io/w5bf9 ). RESULTS We summarised imaging data on SAT, VAT and liver fat from eight published and three previously unpublished datasets, including a total of 1156 South Asian and 2891 white European men, and 697 South Asian and 2271 white European women. Despite South Asian men having a mean BMI approximately 0.5-0.7 kg/m2 lower than white European men (depending on the comparison), nine studies showed 0.34 SMD (95% CI 0.12, 0.55; I2=83%) more SAT and seven studies showed 0.56 SMD (95% CI 0.14, 0.98; I2=93%) more liver fat, but nine studies had similar VAT (-0.03 SMD; 95% CI -0.24, 0.19; I2=85%) compared with their white European counterparts. South Asian women had an approximately 0.9 kg/m2 lower BMI but 0.31 SMD (95% CI 0.14, 0.48; I2=53%) more liver fat than their white European counterparts in five studies. Subcutaneous fat levels (0.03 SMD; 95% CI -0.17, 0.23; I2=72%) and VAT levels (0.04 SMD; 95% CI -0.16, 0.24; I2=71%) did not differ significantly between ethnic groups in eight studies of women. CONCLUSIONS/INTERPRETATION South Asian men and women appear to store more ectopic fat in the liver compared with their white European counterparts with similar BMI levels. Given the emerging understanding of the importance of liver fat in diabetes pathogenesis, these findings help explain the greater diabetes risks in South Asians. FUNDING There was no primary direct funding for undertaking the systematic review and meta-analysis.

Abstract
Objectives Images reconstructed with higher strengths of iterative reconstruction algorithms may impair radiologists' subjective perception and diagnostic performance due to changes in the amplitude of different spatial frequencies of noise. The aim of the present study was to ascertain if radiologists can learn to adapt to the unusual appearance of images produced by higher strengths of Advanced modeled iterative reconstruction algorithm (ADMIRE). Methods Two previously published studies evaluated the performance of ADMIRE in non-contrast and contrast-enhanced abdominal CT. Images from 25 (first material) and 50 (second material) patients, were reconstructed with ADMIRE strengths 3, 5 (AD3, AD5) and filtered back projection (FBP). Radiologists assessed the images using image criteria from the European guidelines for quality criteria in CT. To ascertain if there was a learning effect, new analyses of data from the two studies was performed by introducing a time variable in the mixed-effects ordinal logistic regression model. Results In both materials, a significant negative attitude to ADMIRE 5 at the beginning of the viewing was strengthened during the progress of the reviews for both liver parenchyma (first material: -0.70, p < 0.01, second material: -0.96, p < 0.001) and overall image quality (first material:-0.59, p < 0.05, second material::-1.26, p < 0.001). For ADMIRE 3, an early positive attitude for the algorithm was noted, with no significant change over time for all criteria except one (overall image quality), where a significant negative trend over time (-1.08, p < 0.001) was seen in the second material. Conclusions With progression of reviews in both materials, an increasing dislike for ADMIRE 5 images was apparent for two image criteria. In this time perspective (weeks or months), no learning effect towards accepting the algorithm could be demonstrated.

Abstract
OBJECTIVE The Observing a Decade of Yearly Standardised Surveillance in EVAR patients with Ultrasound or CT Scan (ODYSSEUS) study was conducted to assess differences in outcomes of patients with continued or discontinued yearly follow up after endovascular abdominal aortic aneurysm repair (EVAR). Earlier results of this study showed that discontinued follow up was not associated with poor outcomes. Therefore, an incremental cost analysis and budget impact analysis of de-implementation of yearly imaging following EVAR was performed. METHODS In total, 1 596 patients from the ODYSSEUS study were included. The expected cost savings were assessed if yearly imaging was reduced in patients with a post-operative computed tomography angiogram without abnormalities made around 30 days after EVAR. Costs were derived from the Dutch costs manual, benchmark cost prices, and literature review. Costs were expressed in euros (€) and displayed at 2019 prices. Sensitivity analysis was performed by varying costs. RESULTS A difference of 24% in cost was found between patients with continued and discontinued imaging follow up. The cost per patient was €1 935 in the continued group vs. €1 603 per patient in the discontinued group at five years post-EVAR, with a mean difference of €332 (95% bias corrected and accelerated bootstrap confidence interval -741 to 114). De-implementation of yearly imaging would result in an annual nationwide cost saving of €678 471. Sensitivity analysis with variation in adherence rates, imaging, or secondary intervention costs resulted in a saving of at least €271 388 per year. CONCLUSION This study provided an in depth analysis of hospital costs for post-EVAR patients in the Netherlands with a modest impact on the Dutch healthcare budget.

Abstract
Open thoracoabdominal and abdominal aortic aneurysm repairs are some of the most challenging cases for anesthesiologists because of the potential for rapid blood loss combined with clamping and reperfusion, potential use of left heart bypass, the potential need for lung isolation, and potential placement and management of a spinal drain. In addition, patients often present with other significant comorbidities and a detailed understanding of the disease process, the complex physiology throughout the case, and the intricacies of organ protection are critical.

Abstract
PURPOSE Abdominal injuries may occur in up to one-third of all patients who suffer severe trauma, but little is known about epidemiological trends and characteristics in a Northern European setting. This study investigated injury demographics, and epidemiological trends in trauma patients admitted with abdominal injuries. METHODS This was an observational cohort study of all consecutive patients admitted to Stavanger University Hospital (SUH) with a documented abdominal injury between January 2004 and December 2018. Injury demographics, age- and sex-adjusted incidence, and mortality patterns are analyzed across three time periods. RESULTS Among 7202 admitted trauma patients, 449 (6.2%) suffered abdominal injuries. The median age was 31 years, and the age increased significantly over time (from a median of 25 years to a median of 38.5 years; p = 0.020). Patients with ASA 2 and 3 increased significantly over time. Men accounted for 70% (316/449). The injury mechanism was blunt in 91% (409/449). Transport-related accidents were the most frequent cause of injury in 57% (257/449). The median Injury Severity Score (ISS) was 21, and the median New Injury Severity Score (NISS) was 25. The annual adjusted incidence of all abdominal injuries was 7.2 per 100,000. Solid-organ injuries showed an annual adjusted incidence of 5.7 per 100,000. The most frequent organ injury was liver injury, found in 38% (169/449). Multiple abdominal injuries were recorded in 44% (197/449) and polytrauma in 51% (231/449) of the patients. Overall 30-day mortality was 12.5% (56/449) and 90-day mortality 13.6% (61/449). CONCLUSION The overall adjusted incidence rate of abdominal injuries remained stable. Age at presentation increased by over a decade, more often presenting with pre-existing comorbidities (ASA 2 and 3). The proportion of polytrauma patients was significantly reduced over time. Mortality rates were declining, although not statistically significant.

Abstract
Non-invasive pressure and flow data from Venturi-based sensors can be used with validated models to identify patient-specific lung mechanics. To validate applied respiratory models a secondary measurement is required. Rotary encoder-based tape measures were designed to capture change in circumference of a subject's thorax and diaphragm. Circumferential changes can be correlated to measured or modelled change in lung volume and associated muscular recruitment measures (patient work of breathing). Hence, these simple measurement devices can expedite respiratory research, by adding low-cost, accessible, and clinically useful measurements.

Abstract
Since severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) first appeared in China in December 2019, the globe has been dealing with an ever-increasing incidence of coronavirus disease 2019 (COVID-19). In addition to respiratory disorders, 40% of patients present with gastrointestinal (GI) involvement. Abdominal pain is the most common indication for computed tomography (CT) and ultrasonography. After GI tract involvement, solid visceral organ infarction is the most prevalent abdominal abnormality in COVID-19. This review aims to gather the available data in the literature about imaging features of solid abdominal organs in patients with COVID-19. Gallbladder wall thickening and distension, cholelithiasis, hyperdense biliary sludge, acalculous cholecystitis, periportal edema, heterogeneous liver enhancement, and liver hypodensity and infarction are among hepatobiliary imaging findings in CT, particularly in patients admitted to ICU. Pancreatic involvement can develop as a result of direct SARS-CoV2 invasion with signs of acute pancreatitis in abdominal CT, such as edema and inflammation of the pancreas. Infarction was the most prevalent renal and splenic involvement in patients with COVID-19 who underwent abdominal CT presenting with areas of parenchymal hypodensity. In conclusion, although solid abdominal organs are rarely affected by COVID-19, clinicians must be familiar with the manifestations since they are associated with the disease severity and poor outcome.

Abstract
Background The computed tomography (CT) and ultrasonography (US) features of lymph nodes of the abdomen, pelvis, and hindlimb in healthy cats are poorly described in the current literature. A prospective anatomic and reference interval study was therefore performed. The lymph nodes of six feline cadavers were identified, and dimensions were measured (length, width, and height). The lymph nodes from 30 healthy adult cats were identified and measured using CT (pre- and postcontrast) and US. The identification and dimensions of the separate lymph nodes were compared between imaging techniques and the anatomic study. Results The identification of lymph nodes was most frequent in CT, and the dimensions were overall larger than those identified and measured in US and the anatomic study. The caudal epigastric and sacral lymph nodes were not identified in the anatomic study. The ischiatic, lumbar aortic, internal iliac, and caudal epigastric lymph nodes were not visualized in US. The height presented the main statistical differences among techniques. The lymph nodes were mainly homogeneous in pre- and postcontrast CT and US images. Some lymph nodes showed a hyperattenuating periphery with a hypoattenuating center (on pre- and postcontrast images) and a hypo-/isoechoic periphery with a hyperechoic center, representing the hilar fat. The lymph nodes were commonly elongated and rounded except for the jejunal lymph nodes, which had an irregular shape. Conclusions The assessment of most of the abdominal, pelvic, and hindlimb lymph nodes in the cat is feasible using CT and US, with CT performing best. Factors like the amount of adipose tissue and contrast administration subjectively improved the lymph node visualization and assessment. The measurements and features reported are proposed as reference values. Supplementary Information The online version contains supplementary material available at 10.1186/s13028-022-00638-x.

Abstract
Abdominal radiology as a field has historically played an important role in the training, research, and performance of image-guided procedures. With the emphasis on increased subspecialization and the more formal and rigorous interventional radiology training programs, the question of the future of image-guided procedures within abdominal radiology is explored. A survey conducted by the Cross-Sectional Interventional Radiology Emerging Technology Commission on members of the Society of Abdominal Radiology showed that image-guided procedures are overwhelmingly being performed by abdominal radiology groups, and the vast majority of programs are training their fellows in this regard. We explore some of the challenges radiology and health care in general may face should abdominal radiologists no longer perform procedures and outline strategies departments can employ to meet the needs of both abdominal and interventional radiologists.

Abstract
Since COVID-19 has spread worldwide, the role of imaging for early detection of the disease has become more prominent. Abdominal symptoms in COVID-19 are common in addition to respiratory manifestations. This review collected the available data about abdominal computed tomography (CT) and ultrasonography indications in hollow abdominal organs in patients with COVID-19 and their findings. Since abdominal imaging is less frequently used in COVID-19, there is limited information about the gastrointestinal findings. The most common indications for abdominal CT in patients with COVID-19 were abdominal pain and sepsis. Bowel wall thickening and fluid-filled colon were the most common findings in abdominal imaging. Acute mesenteric ischemia (AMI) was one of the COVID-19 presentations secondary to coagulation dysfunction. AMI manifests with sudden abdominal pain associated with high morbidity and mortality in admitted patients; therefore, CT angiography should be considered for early diagnosis of AMI. Ultrasonography is a practical modality because of its availability, safety, rapidity, and ability to be used at the bedside. Clinicians and radiologists should be alert to indications and findings of abdominal imaging modalities in COVID-19 to diagnose the disease and its potentially serious complications promptly.

Abstract
BACKGROUND There is limited evidence regarding the overall feasibility and success rates of the laparoscopic approach in major emergency surgery, despite its potential to improve outcomes. This study aims to investigate the association between patient, procedural, and surgical factors and likelihood of successful laparoscopic completion in emergency major surgery and derive a predictive model to aid clinical decision-making. METHOD All patients recorded in the NELA emergency laparotomy database 1 December 2013-31 November 2018 who underwent laparoscopically attempted surgery were included. A retrospective cohort multivariable regression analysis was conducted for the outcome of conversion to open surgery. A predictive model was developed and internally validated. RESULTS Of 118,355 patients, 17,040 (7.7%) underwent attempted laparoscopic surgery, of which 7.915 (46.4%) were converted to open surgery. Procedure type was the strongest predictor of conversion (compared to washout as reference, small bowel resection OR 25.93 (95% CI 20.42-32.94), right colectomy OR 6.92 (5.5-8.71)). Diagnostic [free pus, blood, or blood OR 3.67 (3.29-4.1)] and surgeon [subspecialist surgeon OR 0.56 (0.52-0.61)] factors were also significant, whereas age, gender, and pre-operative mortality risk were not. A derived predictive model had high internal validity, C-index 0.758 (95% CI 0.748-0.768), and is available for free-use online. CONCLUSION Surgical, patient, and diagnostic variables can be used to predict likelihood of laparoscopic success with a high degree of accuracy. This information can be used to inform peri-operative decision-making and patient selection.

Abstract
BACKGROUND Abdominal fibromatosis presenting as an abdominal mass is a rare occurrence in a gynecological setting. The diagnosis might not be suspected preoperatively, and management could be challenging. CASE An 18-year-old girl with ovarian germ cell malignancy was managed with staging laparotomy and chemotherapy. She developed a large abdominal mass 10 months later. An abdominopelvic mass (40 × 20 cm) was removed at laparotomy. The histopathological diagnosis was intra-abdominal fibromatosis. A rapidly growing abdominal mass recurred postoperatively. After discussion with the tumor board, chemotherapy with methotrexate and vinblastine was started. The tumor was not responsive, and the patient succumbed after the second cycle of chemotherapy. SUMMARY AND CONCLUSION Abdominal fibromatosis should be considered among the differential diagnoses of a rapidly growing abdominal mass after resection of an ovarian germ cell tumor.

Abstract
BACKGROUND/OBJECTIVES Tuberculosis is a multisystem disease that might affect any organ. Abdominal tuberculosis (ABT) represents 5-17% from all extrapulmonary tuberculosis (EPT) sites. We aimed to study the clinical, laboratory and evolutionary features of ABT cases and to identify predictive factors associated with ABT. METHODS We conducted a retrospective study including all patients hospitalized in the infectious diseases department for EPT between 1991 and 2019. We studied the characteristics of ABT cases, and we compared them with other EPT cases. RESULTS We identified 519 patients with EPT, among whom 86 (16.6%) patients had ABT. There were 58 females (67.4%). Peritoneal tuberculosis was the most common clinical form of ABT (68.6%), followed by intestinal tuberculosis (18.6%). Patients aged 60 years and above were significantly less affected with ABT (odds ratio (OR) = 0.2; p = 0.001). The revealing systemic symptoms including fever (OR = 2.04; p = 0.006), weight loss (OR = 2.5; p < 0.001) and anorexia (OR = 1.7; p = 0.021) were significantly more frequent among ABT patients. Inflammatory markers including C-reactive protein levels (37 [10-89] mg/l vs 10 [4-57] mg/l; p < 0.001) and erythrocyte sedimentation rates (43 [15-95] mm/h vs 27 [15-60] mm/h; p = 0.044) were significantly higher among ABT cases. Multivariate logistic regression analysis showed that anorexia (adjusted OR (AOR) = 1.9; p = 0.015) and pulmonary involvement (AOR = 3.3; p = 0.002) were independent predictors of higher rate of ABT. Concomitant involvement of neuro-meningeal (AOR = 0.18; p = 0.001) and osteo-articular (AOR = 0.2; p = 0.01) sites, 40-59 (AOR = 0.2; p < 0.001) and ≥60 (AOR = 0.2; p < 0.001) age groups as well as hemoglobin rate (AOR = 0.7; p < 0.001) were independently associated with lower rate of ABT. CONCLUSIONS Anorexia and pulmonary involvement were independent predictors of higher rate of ABT. Concomitant involvement of neuro-meningeal and osteo-articular sites, 40-59 and ≥60 age groups and hemoglobin rate were independently associated with lower rate of ABT.

Abstract
BACKGROUND We performed a retrospective study of patients who underwent abdominoplasty to determine the predisposing factors for complications. METHODS Between 2013 and 2016, 235 patients underwent abdominoplasty at the Brugmann University Hospital. The risk factors for the complications studied were: sex, body mass index (BMI)≥30, active smoking, diabetes, high blood pressure, previous abdominal surgery, weight loss, other associated surgical procedures, liposuction, muscle diastasis correction and the duration of presence of the suction drains. The complications were divided into three groups: major complications requiring a second intervention within the first 15 days, minor complications only requiring local treatment and aesthetic complications corrected at a later stage. RESULTS Complications were observed in 46.5% of the patients: 19% were major complications, 69% minor complications and 12% aesthetic complications. The significant risk factors for complications were: BMI ≥30, weight loss, associated surgical procedures and suction drains left in place for more than 3 days. We also analysed combinations of risk factors and we found, for example, that certain combinations such as active smoking and previous abdominal surgery increased the risk significantly. CONCLUSIONS Abdominoplasty is a common plastic surgery procedure associated with an increased risk for complications in certain patients. In our study, a high complication rate was observed, probably because our population was mostly obese and many cases needed an additional procedure. There are no clear guidelines for the surgeon to choose the best surgical candidate. However, risk factors should be taken into consideration and explained to the patient before the surgical decision.
