Abstract
Traumatic duodenal injuries are rare and often challenging to diagnose and treat. Management of these injuries remains controversial and continues to evolve. Here, we performed a review of the literature and guidelines for the diagnosis and management of traumatic duodenal injuries. A common recommendation in more recent literature is primary, tension-free repair of duodenal injuries when possible if surgical repair is necessary. Conversely, if duodenal injuries are unamenable to primary repair, more complex procedures such as Roux-en-Y duodenojejunostomy or pancreaticoduodenectomy may be necessary. Regardless of injury grade or type of surgical repair, the literature continues to support wide extraluminal drainage. Over time, the management of complex duodenal injuries has evolved to favor simple primary repair whenever possible. According to recent studies, more complex procedures are associated with higher rates of post-operative complications and should be reserved for severe injuries when primary repair is not possible.

Diagnostic Accuracy of Computed Tomography for the Prediction of the Need for Laparotomy for Traumatic Hollow Viscus Injury: Systematic Review and Meta-Analysis. J Pers Med 2021; 11:jpm11121269. [PMID: 34945741 PMCID: PMC8708608 DOI: 10.3390/jpm11121269] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 11/23/2021] [Accepted: 11/24/2021] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND Traumatic hollow viscus injury (THVI) is one of the most difficult challenges in the trauma setting. Computed tomography (CT) is the most common modality used to diagnose THVI; however, various performance outcomes of CT have been reported. We conducted a systematic review and meta-analysis to analyze how precise and reliable CT is as a tool for the assessment of THVI. METHOD A systematic review and meta-analysis were conducted on studies on the use of CT to diagnose THVI. Publications were retrieved by performing structured searches in databases, review articles and major textbooks. For the statistical analysis, summary receiver operating characteristic (SROC) curves were constructed using hierarchical models. RESULTS Sixteen studies enrolling 12,514 patients were eligible for the final analysis. The summary sensitivity and specificity of CT for the diagnosis of THVI were 0.678 (95% CI: 0.501-0.809) and 0.969 (95% CI: 0.920-0.989), respectively. The summary false positive rate was 0.031 (95% CI 0.011-0.071). CONCLUSION In this meta-analysis, we found that CT had indeterminate sensitivity and excellent specificity for the diagnosis of THVI.

A retrospective study from the National Trauma Data Bank. Surgery 2021; 171:526-532. [PMID: 34266649 DOI: 10.1016/j.surg.2021.06.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2021] [Revised: 06/02/2021] [Accepted: 06/15/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND In the management of patients with blunt abdominal trauma, delayed diagnosis and treatment of hollow viscus injury can occur. We assessed the effect of the time to surgery on the outcomes of blunt hollow viscus injury patients. METHODS The National Trauma Data Bank was queried from 2012 to 2015 to identify patients with blunt hollow viscus injury for inclusion. Patients with unstable hemodynamics, concomitant intra-abdominal organ injuries, or other severe extra-abdominal injuries were excluded. Inverse probability of treatment weighting and multivariate logistic regression were used to evaluate the effect of the time to surgery on the outcomes. RESULTS In total, 2,997 patients with blunt hollow viscus injury were studied; the mean time to abdominal surgery was 6.7 hours. Twenty-two hours was selected as a cutoff value for further analyses because of an observed transition zone at that time in the distribution of mortality and severe sepsis rates. After adjustment, patients who underwent surgery within 22 hours had a significantly lower mortality rate (1.2% vs 4.2%), lower sepsis rate (0.9% vs 4.5%), shorter hospital length of stay (8.7 vs 12.0 days), and shorter intensive care unit length of stay (1.4 vs 3.3 days). In patients who underwent surgery within 22 hours, neither mortality nor sepsis were affected significantly by the time to surgery. CONCLUSION In the management of patients with blunt hollow viscus injury, early surgical treatment is needed. Patients with isolated blunt hollow viscus injury may have a poor outcome if they undergo abdominal surgery more than 22 hours after arrival in the emergency department.

Abstract
Abstract
Objectives To determine the most preferable endoluminal contrast agent among mannitol, polyethylene glycol (PEG), iohexol, and water by comparing various qualitative (distension, fold visibility, and homogeneity) and quantitative parameters (distension) along with artifacts and patient feedback for computed tomography enterography (CTE).
Methods This was a prospective study including 120 patients of age more than or equal to 18 years who were randomized equally into four groups. Group 1 was given 1500 mL of 3% mannitol solution, group 2 was given 1500 mL of PEG, group 3 was given 20 mL of iohexol dissolved in 1500 mL of water, and group 4 was given 1500 mL of plain water. CTE was done and images were evaluated in axial and coronal planes. Various quantitative and qualitative parameters were taken at the level of second part of duodenum, jejunum, ileum and ileocecal junction (ICJ). Artifacts and patient feedback were also taken into consideration.
Results The quantitative distension and grading, qualitative distension, fold visibility, and homogeneity of the second part of duodenum, jejunum at the level of superior mesenteric artery, inferior mesenteric artery and renal artery on both sides of abdomen, ileum at the level of aortic bifurcation, common iliac bifurcation, and deep pelvis on both sides of abdomen and ICJ were significantly more in PEG group as compared with mannitol group, followed by iohexol and water group. The results were calculated by ANOVA test using p-value. In terms of patient feedback and artifacts, water was the best agent.
Conclusions PEG is the most suitable contrast agent to carry out CTE. Distension, fold visibility, and homogeneity are the essential features for a better diagnostic outcome of CTE, which was better with PEG.

Abstract
BACKGROUND Patients with hollow viscus injury (HVI) are often a cause for diagnostic uncertainty. The incidence and outcomes of patients suffering hollow viscus injury secondary to major trauma have not been previously described in New Zealand. These metrics are important to guide quality improvement and resource allocation. The aim of our study is to define the incidence, outcomes and effect of delayed intervention on patients admitted to hospital with hollow viscus injury secondary to blunt abdominal trauma in the Northern region of New Zealand. METHODS A 4-year multicentre retrospective study was performed in the Northern region of New Zealand between 1 July 2015 and 30 June 2019. A primary cohort of patients with confirmed hollow viscus injury secondary to blunt abdominal injury, who underwent a laparotomy, were assessed. The primary outcome measures were incidence, 30-day mortality and morbidity. Secondary outcomes included the effect of timing of surgical intervention. RESULTS The incidence of hollow viscus injury in the region was 2.03 per 100 000. The 30-day mortality rate was 5% and the 30-day morbidity rate was 82%. Immediate surgical intervention was carried out in 36%, early surgical intervention in 56% and delayed surgical intervention in 8%. CONCLUSION The incidence of hollow viscus injury is in keeping with similar studies, but with lower mortality and higher morbidity. The rate of immediate or early surgical intervention was high. These findings are important to clinicians managing patients with major trauma and those involved in planning and allocation of resources.

Abstract
The colon is the second most commonly injured intra-abdominal organ in penetrating trauma. Management of traumatic colon injuries has evolved significantly over the past 200 years. Traumatic colon injuries can have a wide spectrum of severity, presentation, and management options. There is strong evidence that most non-destructive colon injuries can be successfully managed with primary repair or primary anastomosis. The management of destructive colon injuries remains controversial with most favoring resection with primary anastomosis and others favor colonic diversion in specific circumstances. The historical management of traumatic colon injuries, common mechanisms of injury, demographics, presentation, assessment, diagnosis, management, and complications of traumatic colon injuries both in civilian and military practice are reviewed. The damage control revolution has added another layer of complexity to management with continued controversy.

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
Duodeno-pancreatic and extrahepatic biliary tree injuries are rare in both adult and pediatric trauma patients, and due to their anatomical location, associated injuries are very common. Mortality is primarily related to associated injuries, but morbidity remains high even in isolated injuries. Optimal management of duodeno-bilio-pancreatic injuries is dictated primarily by hemodynamic stability, clinical presentation, and grade of injury. Endoscopic and percutaneous interventions have increased the ability to non-operatively manage these injuries. Late diagnosis and treatment are both associated to increased morbidity and mortality. Sequelae of late presentations of pancreatic injury and complications of severe pancreatic trauma are also increasingly addressed endoscopically and with interventional radiology procedures. However, for moderate and severe extrahepatic biliary and severe duodeno-pancreatic injuries, immediate operative intervention is preferred as associated injuries are frequent and commonly present with hemodynamic instability or peritonitis. The aim of this paper is to present the World Society of Emergency Surgery (WSES) and American Association for the Surgery of Trauma (AAST) duodenal, pancreatic, and extrahepatic biliary tree trauma management guidelines.

Abstract
Based on the previous experience of war wound treatment, the treatment of colorectal injury has been changing constantly. Also, since the 1980s, the progress of severe trauma treatment such as CT examinations and damage control strategies has had a profound impact on the treatment of colorectal injury. This article systematically reviews the clinical manifestations, imaging findings, and endoscopic examinations of colorectal injuries, and lists injury assessment pitfalls such as neglecting colorectal injury in blunt wounds, being misdirected by negative sign or supine X-rays, strict indications for laparotomy exploration, or intro-operative omission. The progress of emergency surgery such as staged surgery for colorectal injury, surgical way of colorectal injury during damage control strategy, and treatment of rectal injury in extraperitoneal section is also described in detail. In addition, the pitfalls for emergency treatment are described, including ignoring effects of massive crystal fluid resuscitation on colorectal anastomosis, attaching no importance on the technical points of the colonic injury operation, and performing improper suture for abdominal incisions.

Abstract
INTRODUCTION Hollow viscus injury (HVI) due to blunt abdominal trauma remains a diagnostic challenge, often presenting late and results in delayed intervention. Despite several treatment algorithms, there is currently no consensus on how to manage patients with HVI. The aim of this review was to define clinical outcomes and the effect of delayed intervention in patients with HVI due to blunt abdominal trauma. The primary outcome of interest was difference in mortality between groups. METHODS Based on the preferred reporting items for systematic reviews and meta-analyses statement, a literature search was performed. Studies comparing clinical outcomes in adult patients with hollow viscus injury due to blunt abdominal trauma undergoing early or delayed laparotomy were included. Two independent reviewers screened the abstracts. RESULTS In all, 2288 articles were retrieved. After screening, 11 studies were included. Outcomes in 3812 patients were reported. Overall mortality was 17%. Ten studies reported no difference in mortality between groups. A statistical increase in morbidity was described in five studies, and a trend to increased morbidity was seen in a further two studies. Two studies reported increased mortality in delayed intervention in isolated bowel injury. CONCLUSIONS This systematic review summarises the results of studies considering outcomes in patients with HVI due to blunt abdominal trauma who have early vs delayed intervention. Overall mortality was significant at 17%. If all patients with hollow viscus injury are considered, the majority of studies do not show an increase in mortality. As patients with isolated bowel injuries have higher mortality in the studies reviewed, to improve outcomes in this subset further investigation is warranted.

Abstract
INTRODUCTION Significant blunt bowel and mesenteric injuries (sBBMI) are frequently missed despite the widespread use of computed tomography (CT). Early treatment improves the outcome related to these injuries. The aim of this study was to assess the prevalence of sBBMI, the incidence of delayed diagnosis and to test the performance of the Bowel Injury Prediction Score (BIPS), determined by the white blood cell (WBC) count, presence or absence of abdominal tenderness and CT grade of mesenteric injury. PATIENTS AND METHODS Single-centre, registry-based retrospective cohort study, screening all consecutive trauma patients admitted to Lausanne University Hospital Trauma Centre from 2008 to 2015 after a road traffic accident. All patients with reliable information about the presence or absence of sBBMI who underwent abdominal CT and for whom calculation of the BIPS was possible were included for analysis. The incidence of delayed (>24h after admission) diagnosis in the patient group with sBBMI was determined and the diagnostic performance of the BIPS for sBBMI was assessed. RESULTS For analysis, 766 patients with reliable information about the presence or absence of sBBMI were included. The prevalence of sBBMI was 3.1% (24/766). In 24% (5/21) of stable trauma patients undergoing CT, a diagnostic delay of more than 24h occurred. Abdominal tenderness (p<0.0001) and CT grade ≥4 (p<0.0001) were associated with sBBMI, whereas CT grade 4 alone (p=0.93) and WBC count ≥17G/l (p=0.30) were not. A BIPS ≥2 had a sensitivity of 89% (95% CI, 67-99), specificity of 89% (95% CI, 86-91), positive likelihood ratio of 8 (95% CI, 6.1-10), negative likelihood ratio of 0.12 (95% CI, 0.03-0.44), positive predictive value (PPV) of 19% (95% CI, 15-24) and negative predictive value (NPV) of 99.7% (95% CI, 98.7-99.9). CT alone identified 79% (15/19) and the BIPS 89% (17/19) of patients with sBBMI (p=0.66). CONCLUSIONS Diagnostic delays in patients with sBBMI are common (24%), despite the routine use of abdominal CT. Application of the BIPS on the present cohort would have led to a high number of non-therapeutic abdominal explorations without identifying significantly more sBBMI early than CT alone.

Abstract
PURPOSE To investigate whether peritoneal fluid of low CT Hounsfield units is an important screening criterion for traumatic bowel perforation. MATERIALS AND METHODS We performed a retrospective study on two cohorts of blunt trauma patients who had peritoneal fluid. Intravenous and oral contrast was used for the first cohort (61 patients) as opposed to intravenous contrast only for the second cohort (60 patients). We compared the CT Hounsfield units of peritoneal fluid with bowel perforation. The optimal cutoff value of CT Hounsfield units was determined, and its diagnostic values for bowel perforation were calculated. RESULTS The mean CT Hounsfield units (HU) of peritoneal fluid with bowel perforation were significantly lower (30.3 ± 9.0 versus 44.1 ± 13.6 HU, p = 0.008) in the second cohort. The optimal cutoff value was 43 HU, and its sensitivity, specificity, accuracy and positive likelihood ratio were 100.0, 69.2, 73.3% and 3.3, respectively, for bowel perforation. Comparisons of CT HUs of peritoneal fluid with bowel perforation in the first cohort that used additional oral contrast for CT did not show statistically significant differences. CONCLUSION Peritoneal fluid of low CT HU is a sensitive and important CT screening criterion for traumatic bowel perforation.

Abstract
OBJECTIVE to evaluate the impact of the new technology of multidetector computed tomography (MDCT) in improving the accuracy and early diagnosis of BSBI. METHODS patients with blunt small bowel injuries (BSBI) grade> I were identified retrospectively and their CT scans reviewed by an experienced radiologist. Clinical and tomographic findings were analyzed and patients grouped as "pre-MDCT" and "post-MDCT", according to the time of implementation of a 64-slice MDCT. RESULTS of the 26 patients with BSBI 16 had CT scans. Motor vehicle collision (62.5%) was the most frequent mechanism of injury. In the pre-MDCT period, five of the 13 patients (38.5%) had abdominal CT, and in the post-MDCT, 11 of 13 patients (84.6%) had the exam. During pre-MDCT, all CT scans were abnormal with findings of pneumoperitoneum (60%), free fluid (40%) and bowel wall enhancement (20%). In the post-MDCT group, all exams but one were abnormal and the most frequent findings were free fluid (90.9%), bowel wall enhancement (72.7%), and pneumoperitoneum (54.5%). However, the rate of delayed laparotomy did not change. The mortality rate in both groups were similar, with 20% during pre-MDCT and 18.2% during post-MDCT. CONCLUSION the use of MDCT in abdominal trauma in our service has increased the sensibility of the diagnosis, but has had no impact on outcome so far.

Abstract
Colonic perforations can be classified into perforations that occur at the site of a localized pathologic process and cecal perforations that occur secondary to distal colonic obstructions. Rectal perforations may result from foreign bodies inserted into the rectum; moreover, deep rectal biopsies, polypectomy, improper cleansing enema, or thermometer placement may also lead to rectal perforation. Correct identification of the cause and site of the perforation is crucial for appropriate management and surgical planning. Multidetector row computed tomography has a pivot role in planning the type of operative treatment, the prognosis, and in assessing those patients who have clinical symptoms of peritonitis but no radiographic signs of perforation.

Abstract
OBJECTIVE In this article, we illustrate imaging findings of colorectal emergencies encountered in the acute setting that are primarily noninfectious and noninflammatory in origin. Our review should enable the reader to identify and understand common colorectal emergencies and related complications in clinical practice. CONCLUSION The diagnosis of colorectal emergencies is mostly straightforward, but it can be challenging because of the overlap of presenting symptoms and imaging findings. Therefore, it is essential to clarify the cause, narrow the differential diagnosis, and identify associated complications.

Abstract
The bowel and the mesentery represent the third most frequently involved structures in blunt abdominal trauma after the liver and the spleen. Clinical assessment alone in patients with suspected intestinal and/or mesenteric injury from blunt abdominal trauma is associated with unacceptable diagnostic delays. Multi-detector computed tomography, thanks to its high spatial, time and contrast resolutions, allows a prompt identification and proper classification of such conditions. The radiologist, in fact, is asked not only to identify the signs of trauma but also to provide an indication of their clinical significance, suggesting the chance of conservative treatment in the cases of mild and moderate, non-complicated or self-limiting injuries and focusing on life-threatening conditions which may benefit from immediate surgical or interventional procedures. Specific and non-specific CT signs of bowel and mesenteric injuries from blunt abdominal trauma are reviewed in this paper.

Abstract
AIM: To assess and compare the image quality of 4% sorbitol and diluted iodine 2% (positive oral contrast agent) in abdomino-pelvic multi-detector computed tomography.
METHODS: Two-hundred patients, referred to the Radiology Department of a central educational hospital for multi-detector row abdominal-pelvic computed tomography, were randomly divided into two groups: the first group received 1500 mL of 4% sorbitol solution as a neutral contrast agent, while in the second group 1500 mL of meglumin solution as a positive contrast agent was administered in a one-way randomized prospective study. The results were independently reviewed by two radiologists. Luminal distension and mural thickness and mucosal enhancement were compared between the two groups. Statistical analysis of the results was performed by Statistical Package for the Social Sciences software version 16 and the Mann-Whitney test at a confidence level of 95%.
RESULTS: Use of neutral oral contrast agent significantly improved visualization of the small bowel wall thickness and mural appearance in comparison with administration of positive contrast agent (P < 0.01). In patients who received sorbitol, the small bowel showed better distention compared with those who received iodine solution as a positive contrast agent (P < 0.05).
CONCLUSION: The results of the study demonstrated that oral administration of sorbitol solution allows better luminal distention and visualization of mural features than iodine solution as a positive contrast agent.

Abstract
PURPOSE We compare radiation exposure from body CT imaging for blunt trauma performed at outside hospitals (OH) versus our children's hospital (CH). METHODS We performed a retrospective chart review of all children transferred to our facility for management of trauma after undergoing a body CT scan at an OH from June 2011 to August 2013. Radiation from OH images was compared to our CH by matching to age, gender, and nearest date. Radiation measures included dose length product (DLP), computed tomography dose index (CTDI), and size-specific dose estimate (SSDE). RESULTS Fifty-one children were transferred from 39 OH. Abdomen/pelvis and chest/abdomen/pelvis imaging was performed in 30 and 21 children, respectively. Demographics are shown in Table 1. Results are illustrated in Tables 2 and 3. Contrast was utilized in 45 (1 oral, 41 IV, 3 both) and 51 (49 IV, 2 both). CT scans were performed at OH and CH, respectively (P=0.03). CONCLUSIONS Children receive significantly less radiation exposure with body CT imaging for blunt trauma when performed at our dedicated CH. CT scans were significantly more likely to be ordered with appropriate contrast at our CH.

Abstract
INTRODUCTION Transcatheter arterial embolization (TAE) is usually necessary in the management of hemodynamically unstable patients with concomitant pelvic fractures. Given the critical conditions of such patients, TAE is at times performed only according to the results of a primary evaluation without computed tomographic (CT) imaging. Therefore, the evaluation of associated intra-abdominal injuries (IAIs) might be insufficient. Clinically, some patients have required post-TAE laparotomy due to further deterioration. In this study, we attempted to determine a feasible protocol for post-TAE observation. MATERIALS AND METHODS This study focused on patients who received TAE to achieve hemostasis of retroperitoneal hemorrhage and who did not undergo CT imaging due to their unstable hemodynamics. The characteristics of patients with and without associated IAIs requiring post-TAE laparotomy were compared. We also analyzed the effects of the timing of post-TAE CT imaging on patients with IAIs requiring surgery. RESULTS A total of 41 patients were enrolled in the study. Of these patients, all of whom underwent primary TAE without preprocedure CT imaging; 15 patients (15/41, 36.6%) required post-TAE laparotomy due to further deterioration. Comparisons between the 2 patient groups revealed no significant differences in the rate of endotracheal intubation (80.0% vs 65.4%, P=.480), loss of consciousness (66.7% vs 73.1%, P=.730), or abdominal symptoms (20.0% vs 23.1%, P=1.000). CONCLUSION In the management of hemodynamically unstable patients with concomitant pelvic fractures, greater attention should be paid to associated IAIs. Early CT imaging is encouraged after the patient's hemodynamic status is stabilized with TAE.

Abstract
Bowel and mesenteric injuries are relatively uncommon but associated with significant morbidity and mortality. Early recognition is crucial, and multidetector computed tomography (MDCT) now has a central role in the evaluation of patients with a history of trauma. In this review, we describe the MDCT appearances of bowel and mesenteric injuries with reference to findings at surgery. Emphasis is placed on the importance of an understanding of mechanism of injury when interpreting CT findings following abdominal trauma.

Abstract
Blunt bowel and mesenteric injury (BBMI) is frequently a difficult diagnosis at initial presentation. We aimed to study the predictors for early diagnosis and outcomes in patients with BBMI. Data were collected retrospectively from the database registry between January 2008 and December 2011 in the only Level I trauma unit in Qatar. Patients with BBMI were divided into Group A (surgically treated within 8 hours) and Group B (treated after 8 hours). Data were analyzed and χ2, Student's t test, and multivariate regression analysis were performed appropriately. Among 984 patients admitted with blunt abdominal trauma (BAT), 11 per cent had BBMI with mean age of 35 ± 9.5 years. Polytrauma and isolated bowel injury were identified in 53 and 42 per cent, respectively. Mean Injury Severity Score (ISS) was higher in Group A in comparison to Group B (18 ± 11 vs 13 ± 8; P = 0.02). Presence of pain and seatbelt sign ( P = 0.02) were evident in Group B. Hypotension ( P = 0.004) and hypothermia ( P = 0.01) were prominent in Group A. The rate of positive Focused Assessment Sonography for Trauma was greater in Group A ( P = 0.001). Among operative findings, bowel perforation was more frequent in Group B ( P = 0.04), whereas mesenteric full-thickness hematoma was significantly higher in Group A. Pelvic fracture was more frequent finding in Group A ( P = 0.005). The overall mortality rate was 15.6 per cent. In patients with BAT, the presence of abdominal pain, hypotension, ISS greater than 16, hypothermia, pelvic fracture, and mesenteric hematoma might help in early diagnosis of BBMI. Moreover, base deficit and mean ISS were independent predictors of mortality. Delayed operative interventions greater than 8 hours increased morbidity rate but had no significant impact on mortality.

Abstract
Objectives: To evaluate multi-detector CT (MDCT) findings in bowel and mesenteric injury due to blunt abdominal trauma. Method: Retrospective evaluation of MDCT scan reports of patients admitted in Hamad Medical Corporation, Doha, Qatar with bowel and mesenteric injury during the period of January 2005 to April 2008. Results: MDCT, without using oral contrast, clearly demonstrated various specific and less specific findings of bowel and mesenteric injury. Conclusion: Multi-detector CT is an excellent diagnostic modality in bowel and mesenteric injury. Routine administration of oral contrast agent is not mandatory for initial evaluation of these patients.

Abstract
OBJECTIVES To determine whether positive oral contrast agents improve accuracy of abdominopelvic CT compared with no, neutral or negative oral contrast agent. METHODS Literature was searched for studies evaluating the diagnostic performance of abdominopelvic CT with positive oral contrast agents against imaging with no, neutral or negative oral contrast agent. Meta-analysis reviewed studies correlating CT findings of blunt abdominal injury with positive and without oral contrast agents against surgical, autopsy or clinical outcome allowing derivation of pooled sensitivity and specificity. Systematic review was performed on studies with common design and reference standard. RESULTS Thirty-two studies were divided into two groups. Group 1 comprised 15 studies comparing CT with positive and without oral contrast agents. Meta-analysis of five studies from group 1 provided no difference in sensitivity or specificity between CT with positive or without oral contrast agents. Group 2 comprised 17 studies comparing CT with positive and neutral or negative oral contrast agents. Systematic review of 12 studies from group 2 indicated that neutral or negative oral contrasts were as effective as positive oral contrast agents for bowel visualisation. CONCLUSIONS There is no difference in accuracy between CT performed with positive oral contrast agents or with no, neutral or negative oral contrast agent. KEY POINTS • There is no difference in the accuracy of CT with or without oral contrast agent. • There is no difference in the accuracy of CT with Gastrografin or water. • Omission of oral contrast, utilising neutral or negative oral contrast agent saves time, costs and decreases risk of aspiration.

Abstract
The precise role of repeat abdominal computed tomography (CT) imaging in the diagnosis and management of bowel injury is unclear. We reviewed 540 patients with blunt abdominal trauma managed at a Level II trauma center over a 5-year period to better define the role of repeat imaging. One hundred patients had a repeat abdominal CT scan within 72 hours of admission. These patients were young with multisystem injuries (mean ± standard deviation age, 34 ± 15 years; Injury Severity Score, 21 ± 12; Glasgow Coma Score [GCS], 12 ± 5). There were 14 patients with bowel injuries. All bowel-injured patients survived without abdominal morbidity. Time to repeat CT was shortest in the bowel injured group (20 ± 10 hours). The repeat CT was most helpful in patients with significant closed head injury (mean GCS, 3 ± 1) and in those with occult bowel injury. The repeat scan resulted in a change in clinical management in 26 patients. Regarding the presence of bowel perforation, the follow-up scan enhanced sensitivity from 30 to 82 per cent. The repeat abdominal CT is best used selectively in patients with blunt abdominal trauma and can provide clinically useful information to exclude bowel injury.

Multi detector computed tomography in the diagnosis of bowel injury. Indian J Surg 2012; 74:445-50.

Abstract
Bowel Injuries are uncommonly associated with traumatic abdominal injuries. However, they are associated with significant morbidity and mortality and require operative intervention unlike solid organ injuries. Hence, early diagnosis is of paramount importance. Computed tomographic (CT) scan is a well-established and highly accurate imaging modality for the detection of solid organ injury after blunt abdominal trauma. However, its role in diagnosing hollow viscus injury remains controversial. The aim of our study was to analyze the accuracy of multidetector CT (MDCT) in the diagnosis of bowel injury. Imaging features of surgically proven cases of bowel injury were identified over 8-year period (i.e., from January 2003 to December 2010) and were retrospectively analyzed. There were 32 patients with age range of 3-90 years. There was only one female. Sensitivity of various CT signs specific to bowel injury (i.e., extravasation of contrast and discontinuity of bowel wall) was 15.62, and 28.12%, respectively. While that of signs suggestive of bowel injury were pneumoperitoneum, 62.5%; gas in the vicinity, 40.62%; bowel wall hematoma, 21.87%; bowel wall thickening, 75%; ascites, 78.12%; mesenteric hematoma, 46.87%; and mesenteric stranding, 40.62%. Based on the major and minor signs, a diagnosis of bowel injury could be made in all patients except one. The minor signs showed a higher sensitivity than the major signs. Hence, we recommend that multidetector CT should be used as the modality of choice in case of patients with suspected bowel injury. We also suggest that the minor signs should be given as much importance as the major signs.

Abstract
This clinical policy from the American College of Emergency Physicians is an update of the 2004 clinical policy on the critical issues in the evaluation of adult patients presenting to the emergency department with acute blunt abdominal trauma. A writing subcommittee reviewed the literature as part of the process to develop evidence-based recommendations to address 4 key critical questions: (1) In a hemodynamically unstable patient with blunt abdominal trauma, is ultrasound the diagnostic modality of choice? (2) Does oral contrast improve the diagnostic performance of computed tomography (CT) in blunt abdominal trauma? (3) In a clinically stable patient with isolated blunt abdominal trauma, is it safe to discharge the patient after a negative abdominal CT scan result? (4) In patients with isolated blunt abdominal trauma, are there clinical predictors that allow the clinician to identify patients at low risk for adverse events who do not need an abdominal CT? Evidence was graded and recommendations were based on the available data in the medical literature related to the specific clinical question.

Abstract
BACKGROUND With recent advances in radiologic diagnostic procedures, the use of diagnostic peritoneal lavage (DPL) has markedly declined. In this study, we reviewed data to reevaluate the role of DPL in the diagnosis of hollow organ perforation in patients with blunt abdominal trauma. METHODS Adult patients who had sustained blunt abdominal trauma and who were hemodynamically stable after initial resuscitation underwent an abdominal computed tomographic (CT) scan. Diagnostic peritoneal lavage was performed for patients who were indicated to receive nonoperative management and where hollow organ perforation could not be ruled out. RESULTS During a 60-month period, 64 patients who had received abdominal CT scanning underwent DPL. Nineteen patients were diagnosed as having a positive DPL based on cell count ratio of 1 or higher. There were 4 patients who sustained small bowel perforation. The sensitivity and specificity of the cell count ratio for a hollow organ perforation in this study were 100% and 75%, respectively. No missed hollow organ perforations were detected. CONCLUSION For patients with blunt abdominal trauma and hemoperitoneum who plan to receive nonoperative management, DPL is still a useful tool to exclude hollow organ perforation that is undetected by CT.

Abstract
Mesenteric trauma is one of the possible injuries caused by the use of seat belts in case of motor vehicle crash. We report here a rare case of rectal bleeding by rupture of a mesosigmoid haematoma. An emergent laparotomy revealed a mesosigmoid haematoma with a centimetric rectal perforation. The wearing of safety belts added some specific blunt abdominal trauma, which directly depends on lap-and-sash belts. Mesenteric injuries are found out up to 5% of blunt abdominal traumas. "Seat belt mark" leads the surgical team to strongly suspect an intra-abdominal trauma. When "seat belt mark" sign is found, in patients with mild to severe blunt car injuries, CT-scan has to be realised to eliminate intra-abdominal complications, including mesenteric and mesosigmoid ones. In case of proved mesenteric haematoma associated to intestinal bleeding, a surgical treatment must be considered as first choice. Conservative approach remains possible in stable patients but surgical exploration remains necessary in unstable patients with active bleeding.

Abstract
INTRODUCTION Computed tomographic (CT) scans have become invaluable in the management of patients with blunt abdominal trauma. No clear consensus exists on its role in hollow viscus injuries (HVI) and mesenteric injuries (MI). The aim of this study was to correlate operative findings of HVI and MI to findings on pre-operative CT. METHODS All patients treated for blunt abdominal trauma at Tan Tock Seng Hospital from January 2003 to January 2008 were reviewed. CT scans were only performed if the patients were haemodynamically stable and indicated. All scans were performed with intravenous contrast using a 4-slice CT scanner from 2003 to December 2004 and a 64-slice CT scanner from January 2005 onwards. All cases with documented HVI/MI that underwent both CT scans and exploratory laparotomy were analysed. RESULTS Thirty-one patients formed the study group, with median age of 40 (range, 22-65) years and a significant male (83.9%) predominance. Vehicular-related incidents accounted for 67.7% of the injuries and the median Injury Severity Score (ISS) was 13 (4-50). The 2 commonest findings on CT scans were extra-luminal gas (35.5%) and free fluid without significant solid organ injuries (93.5%). During exploratory laparotomy, perforation of hollow viscus (51.6%) occurred more frequently than suspected from the initial CT findings of extra-luminal gas. Other notable findings included haemoperitoneum (64.5%), and mesenteric tears (67.7%). None of our patients with HVI and MI had a normal pre-operative CT scan. CONCLUSION Our study suggests that patients with surgically confirmed HVI and MI found at laparotomy were very likely to have an abnormal pre-operative CT scan. Unexplained free fluid was a very common finding in blunt HVI/MI and is one major indication to consider exploratory laparotomy.

Abstract
Single-pass, whole-body computed tomography (pan-CT) was proposed in the late 1990s as a new concept for the diagnostic work-up of severely injured patients. Since its introduction, it has led to considerable debate among clinicians and scientists, triggered by concerns about its immediate safety, questionable therapeutic advantages and exposure to radiation. However, it was recently shown that pan-CT scanning may be associated with a reduction in trauma mortality. In this article, we provide an overview of current knowledge of the value of this compelling concept. The diagnostic accuracy of multidetector row CT (MDCT) for clearing various anatomical regions in trauma patients is, at best, unclear. Little is known about the accuracy of pan-CT as a whole, which weakens statements about its effectiveness and prevents inferences about survival advantages. This last point may be explained by a stage-migration or "Will Rogers" phenomenon: Pan-CT increases injury severity by detecting lesions that would not have been recognized by conventional methods but still do not affect treatment decisions, thus artificially lowering the ratio of observed to expected deaths. In order to maintain the credibility of pan-CT technology for trauma, a rigorous, large-scale evaluation of its accuracy is required. Such an evaluation requires consensus about the definition of true and false positive and negative findings in the setting of blunt multiple trauma. In addition, triage criteria need to be refined to increase specificity and reduce the number of unnecessary scans.

Abstract
Diagnosis of trauma-related injuries is a key task in modern radiology. Early, thorough and accurate detection of potentially life-threatening injuries is crucial for fast and targeted initiation of treatment. Conventional radiography (CR) and ultrasound (US) are well-established and still represent the basic diagnostic tools for trauma imaging. However, a number of studies have shown a lower detection rate of injuries for radiography and ultrasound compared with computed tomography (CT). Multi-detector CT (MDCT) with its shorter scan time and increased accuracy has become the gold standard for many indications in trauma imaging. As MDCT has a higher radiation dose, its use should be restricted and carefully indicated especially when dealing with a younger patient population. Careful optimization of imaging parameters has to be performed to minimize exposure and maximize diagnostic safety. Modern MDCT examinations produce a large number of images, which have to be limited to a reasonable number for interpretation. This review article focuses on optimization of examination protocols and on how to handle the flood of images for viewing and archiving.

Abstract
BACKGROUND Gastrointestinal and mesenteric injuries (GIMI) are uncommon in trauma patients, and their diagnosis are often delayed. Our aims were to determine the reliability of CT scan in our centre, and to assess the clinical significance of a delayed diagnosis. MATERIALS AND METHOD Retrospective analysis of cases confirmed at laparotomy. Patients were identified at the Severe Trauma Registry of Gregorio Marañón University General Hospital, between 1993 and 2006. RESULTS We found 105 (16.6%) GIMI out of 632 patients with abdominal trauma, in a Registry with 1495 severe trauma cases included. A total of 46% had blunt injuries. The mean injury severity score (ISS) and new ISS (NISS) were 20 and 25, respectively. There were 9 (8.5%) deaths, 4 of which were unexpected. A CT scan was performed in 56 (53%) cases, and only in 37 there were signs suggestive of a GIMI. In another 43 (41%) patients an urgent laparotomy was indicated because of positive clinical findings or instability. Surgery was delayed for more than 8 hours in 21 (20%) patients, the most common reason being a false negative result in the CT scan. CONCLUSIONS The overall incidence of GIMI was high in our centre (31% due to penetration and 10.7% blunt trauma). Several factors, such as the initial lack of symptoms, a low diagnostic sensitivity of the CT scan (34% false negatives), and the non-surgical management of solid organ injuries, have contributed to a delayed diagnosis and treatment in one out of each five patients in our series, but this has not led to a significant increase in septic complications in this group.

BACKGROUND Hollow viscus injuries are uncommon and occur in approximately 1% of all blunt trauma patients. DISCUSSION These injuries are often not suspected and are difficult to diagnosis. Morbidity and mortality are high, and a negative abdominal computed tomography is not sufficient to rule out these injuries in certain clinical scenarios. CONCLUSION Using a case-based approach, the epidemiology and diagnostic pathways to manage hollow viscus injuries are reviewed.

Abstract
BACKGROUND Laparoscopy offers several advantages in the treatment of abdominal stab wounds. In this paper, we report our experience during 2004, where hemodynamically stable patients with stab wounds were managed laparoscopically. PATIENTS AND METHODS Between January and December 2004, 8 hemodynamically stable patients (7 men, 1 woman) underwent laparoscopy for anterior abdominal stab wounds. Median age was 28.5 years (range, 17-55). All patients underwent an abdominal computed tomography (CT) prior to the laparoscopy. RESULTS Exploration of the wound under aseptic conditions, carried out as a part of the physical examination, confirmed peritoneal penetration in 7 of the 8 cases. Abdominal CT revealed positive findings in 7 (87.5%) cases. Laparoscopy was performed after a median time of 60 minutes (range 30-90). Laparoscopic exploration evidenced peritoneal penetration in 100% of the cases and visceral lesions in 87.5% of the cases. All visceral injuries were managed laparoscopically. Median operative time was 135 minutes (range, 45-200). Operative mortality was 0% and early morbidity was 12.5%. Median hospital stay was 5 days (range, 1-11). After a median follow-up of 12 months (range, 1-28), 1 patient complained of persistent chest pain and a ventral hernia at the site of the abdominal stab wound was diagnosed in another patient. CONCLUSIONS Laparoscopy should be included in management algorithms in patients with anterior abdominal stab wounds who are hemodynamically stable. In addition to its diagnostic ability, this study demonstrates that laparoscopy can be an effective management modality with minimal morbidity and no mortality.

Abstract
Emergency practitioners routinely encounter patients who suffer from abdominal trauma, be it blunt or penetrating. These injuries are often confounded by altered mental status, distracting injuries, or lack of historical information, and may present challenges in management. However, in the last several years new approaches to the diagnosis and management of abdominal trauma, including bedside ultrasound, newer generation computed tomography scans, laparoscopy, and the ability for selected nonoperative management expedite identification of life threatening injury and offer new options in treatment.

Abstract
BACKGROUND The optimal management of hemodynamically stable children without solid-organ injury and with intra-abdominal free fluid on computed tomographic (CT) scan is highly debatable. The possibility of hollow viscus injury in this setting has led many to propose mandatory exploration. We think that stable children with intra-abdominal fluid without solid organ injury can be managed nonoperatively. METHODS The charts of all children less than 18 years of age who had an abdominopelvic CT scan after a blunt abdominal trauma between January 2001 and July 2004 were queried. Patient demographics, mechanism of injury, vital signs, physical examination, laboratory data, CT findings, and outcomes of management were reviewed. RESULTS There were 37 pediatric patients identified during the study period who met the selection criteria. Twenty were boys and 17 were girls. Thirty-one patients had a small amount of fluid and six had a moderate amount of fluid. The most common mechanism of injury was motor vehicle crash (MVC). Thirty-one patients were successfully managed nonoperatively. Six patients received an exploratory laparotomy. Intraoperative findings included mesenteric injuries with or without ischemic bowel. There were no cases of hollow viscus perforation. CONCLUSIONS Nonoperative management of stable patients with small amounts of free fluid in the absence of significant abdominal findings is appropriate in the pediatric population. Increasing amounts of tenderness elicited on physical examination correlates well with the presence of more than a small amount of fluid. The presence of seat belt sign and more than a small amount of fluid may be associated with an increased likelihood of operative intervention.

Abstract
OBJECTIVE Abdominal computed tomography has proven accurate for the detection of pediatric solid organ injuries following blunt abdominal trauma but is less reliable in detecting blunt bowel and mesenteric injuries (BBMI). The purpose of this study was to determine the significance of nonspecific findings on abdominal computed tomography (CT) scan in children at risk for BBMI. DESIGN Retrospective chart review. SETTING Regional pediatric trauma center. PATIENTS All patients who received an abdominal CT scan as part of their evaluation following blunt abdominal trauma over a 10-yr period (September 1991 to September 2001). INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Individual records were reviewed by one of the authors and analyzed for age, gender, mechanism of injury, diagnostic studies and procedures, results of initial CT scan, treatment, surgical procedures, complications, and outcome. Patients were excluded if they suffered penetrating trauma, had an abdominal CT scan performed at another institution, had a surgical procedure before CT scan, or had incomplete records. A total of 2,114 patients met inclusion criteria. Sixty-five percent were male and ages ranged from 3 wks to 18 yrs. There were 178 patients who had at least one nonspecific finding on abdominal CT scan suggestive of BBMI; 151 patients had one finding, 24 patients had two findings, and three had three findings. The risk of BBMI increased with the number of nonspecific findings (positive predictive value = 11% with at least one finding and 44% with two or more findings). This increase in positive predictive value, however, was accompanied by a reduction in sensitivity (62% and 37%, respectively). A total of 32 patients had surgically proven BBMI. Of these, eight had a single nonspecific finding on CT scan, ten had two findings, and two had three findings (12 patients had no CT findings suggestive of BBMI). There were complications in four of the 32 patients with BBMI and one death (due to laceration of the superior mesenteric artery). The complications appeared to occur independent of the time to surgical intervention. CONCLUSIONS The presence of multiple nonspecific findings on abdominal CT scan does not reliably predict BBMI in children. Children also appear to suffer complications from BBMI less frequently than adults, regardless of the time to surgery. Therefore, nonspecific findings alone do not warrant surgical exploration. The decision to operate should instead be based on clinical data that include serial physical examinations.

Sixty-four multi-detector row computed tomography (64-MDCT) offers the possibility of increasing the application of CT in multitrauma imaging. 64-MDCT affords significant increases in imaging speed while allowing for subisotropic voxel slice thicknesses. We have recently installed two 64-MDCT scanners in our Level I trauma center. Our routine protocols using these new scanners are detailed. Additionally, this new technology has made possible several novel protocols. These include an increased use of CT angiography in trauma imaging. The acquisition speed and table lengths available with 64-MDCT allow for whole-body scout images. These scout images may be used to plan complex, multistep CT studies incorporating pelvic and extremity angiography, when indicated, into a single study. Imaging speeds afforded by 64-MDCT allow for imaging in any number of phases, over any area to be imaged, all with a single initial bolus of contrast. Image quality afforded by 64-MDCT allows for increasing roles of MPR and 3D reformations. These alternatives to axial images are currently used both for primary interpretation by our trauma radiologists as well as for communication and use by our clinical colleagues. Technical challenges presented by 64-MDCT include further increases in the number of images generated. Currently, datasets may exceed 4,000 images when angiography is included in routine trauma protocols. Radiation doses are also an ever present concern. With the opportunity to image from head to toe in seconds with submillimeter slice thicknesses, radiologists must be constantly vigilant in their efforts to limit radiation. Novel techniques such as automated dose modulation currently offer means of reducing radiation doses. Though several technical challenges are faced, 64-MDCT represents an evolution in multitrauma imaging.
