Abstract
In the United States, gunshot wounds (GSWs) have become a critical public health concern with substantial annual morbidity, disability, and mortality. Vascular injuries associated with GSW may pose a clinical challenge to the physicians in the emergency department. Patients demonstrating hard signs require immediate intervention, whereas patients with soft signs can undergo further diagnostic testing for better injury delineation. Although digital subtraction angiography is the gold standard modality to assess vascular injuries, non-invasive techniques such as Doppler ultrasound, computed tomography angiography, and magnetic resonance angiography have evolved as appropriate alternatives. This article discusses penetrating bodily vascular injuries, specifically ballistic and stab wounds, and the corresponding radiological presentations.

Diagnostic accuracy of computed tomography findings for hollow viscus injuries following thoracoabdominal gunshot wounds. J Trauma Acute Care Surg 2023; 94:156-161. [PMID: 35838238 DOI: 10.1097/ta.0000000000003743] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/07/2023]
Abstract
BACKGROUND Selective nonoperative management (SNOM) of abdominal gunshot wounds (GSWs) is increasingly used as computed tomography (CT) has become a diagnostic adjunct for the evaluation of intraabdominal injuries including hollow viscus injuries (HVIs). Currently, there is scarce data on the diagnostic accuracy of CT for identifying HVI. The purpose of this study was to determine the diagnostic accuracy of different CT findings in the diagnosis of HVI following abdominal GSW. METHODS This retrospective single-center cohort study was performed from January 2015 to April 2019. We included consecutive patients (≥18 years) with abdominal GSW for whom SNOM was attempted and an abdominal CT was obtained as a part of SNOM. Computed tomography findings including abdominal free fluid, diffuse abdominal free air, focal gastrointestinal wall thickness, wall irregularity, abnormal wall enhancement, fat stranding, and mural defect were used as our index tests. Outcomes were determined by the presence of HVI during laparotomy and test performance characteristics were analyzed. RESULTS Among the 212 patients included for final analysis (median age: 28 years), 43 patients (20.3%) underwent a laparotomy with HVI confirmed intraoperatively whereas 169 patients (79.7%) were characterized as not having HVI. The sensitivity of abdominal free fluid was 100% (95% confidence interval [CI]: 92-100). The finding of a mural defect had a high specificity (99%, 95% CI: 97-100). Other findings with high specificity were abnormal wall enhancement (97%, 95% CI: 93-99) and wall irregularity (96%, 95% CI: 92-99). CONCLUSION While there was no singular CT finding that confirmed the diagnosis of HVI following abdominal GSW, the absence of intraabdominal free fluid could be used to rule out HVI. In addition, the presence of a mural defect, abnormal wall enhancement, or wall irregularity is considered as a strong predictor of HVI. LEVEL OF EVIDENCE Diagnostic Test or Criteria; Level II.

Abstract
PURPOSE To analyze the amount of free abdominal gas and ascites on computed tomography (CT) images relative to the location of a perforation. METHODS We retrospectively included 172 consecutive patients (93:79 = m:f) with GIT perforation, who underwent abdominal surgery (ground truth for perforation location). The volume of free air and ascites were quantified on CT images by 4 radiologists and a semiautomated software. The relation of the perforation location (upper/lower GIT) and amount of free air and ascites was analyzed by the Mann-Whitney test. Furthermore, best volume cutoff for upper and lower GIT perforation, areas under the curve (AUC), and interreader volume agreement were assessed. RESULTS There was significantly more abdominal ascites with upper GIT perforation (333 ml, range 5 to 2000 ml) than with lower GIT perforation (100 ml, range 5 to 2000 ml, p = 0.022). The highest volume of free air was found with perforations of the stomach, descending colon and sigmoid colon. Significantly less free air was found with perforations of the small bowel and ascending colon compared to the aforementioned. An ascites volume > 333 ml was associated with an upper GIT perforation demonstrating an AUC of 0.63 ± 0.04. CONCLUSION Using a two-step process based on the volumes of free air and free fluid can help localizing the site of perforation to the upper, middle or lower GI tract.

Abstract
Penetrating abdominopelvic trauma usually results from abdominal cavity violation from a firearm injury or a stab wound and is a leading cause of morbidity and mortality from traumatic injuries. Penetrating trauma can have subtle or complex imaging findings, posing a diagnostic challenge for radiologists. Contrast-enhanced CT is the modality of choice for evaluating penetrating injuries, with good sensitivity and specificity for solid-organ and hollow viscus injuries. Familiarity with the projectile kinetics of penetrating injuries is an important skill set for radiologists and aids in the diagnosis of both overt and subtle injuries. CT trajectography is a useful tool in CT interpretation that allows the identification of subtle injuries from the transfer of kinetic injury from the projectile to surrounding tissue. In CT trajectography, after the entry and exit wounds are delineated, the two points can be connected by placing cross-cursors and swiveling the cut planes obliquely in orthogonal planes to obtain a double-oblique orientation to visualize the wound track in profile. The path of the projectile and its ensuing damage is not always straight, and the imaging characteristics of free fluid of different attenuation in the abdomen (including hemoperitoneum) can support the diagnosis of visceral and vascular injuries. In addition, CT is increasingly used for evaluation of patients after damage control surgery and helps guide the management of injuries that were overlooked at surgery. An invited commentary by Paes and Munera is available online. Online supplemental material is available for this article. ©RSNA, 2021.

Abstract
Penetrating thoracoabdominal injury is a common presentation in the trauma resuscitation room with the possibility of a myriad of injuries which may involve thoracic and abdominal viscera. Management is usually operative however non-operative management is a possibility especially following knife stab injuries when compared with gunshot injuries. Clinical presentation will depend on the injured organ, extent of injury and time from injury to presentation. Unusual presentation of delayed haematemesis is a possibility with injury to the stomach, however, due to its rarity, a high index of suspicion with emergency surgery will help to mitigate the fatal consequences that may follow. This type of presentation is not documented in the available on-line literature which portends the importance of this paper. This case highlights the possibility of this clinical presentation and importance of early management to improve patient outcome.

Abstract
BACKGROUND Use of gastrointestinal (GI) contrast material for computed tomography (CT) diagnosis of hollow viscus injury (HVI) after penetrating abdominal trauma is still controversial. PURPOSE To assess the sensitivity of CT and GI contrast material use in detecting HVI after penetrating abdominal trauma. MATERIAL AND METHODS Retrospective analysis (2013-2016) of patients with penetrating abdominal trauma. Data from the local trauma registry, medical records, and imaging from PACS were reviewed. CT and surgical findings were compared. RESULTS Of 636 patients with penetrating trauma, 177 (163 men, 14 women) had abdominal trauma (mean age 34 years, age range 16-88 years): 155/177 (85%) were imaged with CT on arrival; 128/155 (83%) were stab wounds and 21/155 (14%) were gunshot wounds; 47/155 (30%) had emergent surgery after CT. Two patients were imaged using oral, rectal and i.v. contrast; 23 with rectal and i.v. contrast; and 22 with i.v. contrast only. Surgery revealed HVI in 26 patients. CT had an overall sensitivity 69.2%, specificity 90.5%, PPV 90.0%, and NPV 70.4%. CT with oral and/or rectal contrast (n = 25) had sensitivity 66.7%, specificity 71.4%, PPV 85.7%, and NPV 45.5%. CT with i.v. contrast only (n = 22) had 75% sensitivity, 100% specificity, PPV 100%, and NPV 87.5%. No statistically significant difference was found between sensitivity of CT with GI contrast material and i.v. contrast only (P = 1). CONCLUSION Stab wounds were the most common cause of penetrating abdominal trauma. CT had 69.2% sensitivity and 90.5% specificity in detecting HVI. CT with GI contrast had similar sensitivity as CT with i.v. contrast only.

Abstract
BACKGROUND. Scarce evidence exists on the diagnostic benefit of enteric contrast administration for abdominopelvic CT performed in the setting of penetrating trauma. OBJECTIVE. The purpose of this systematic review and meta-analysis is to compare the diagnostic accuracy of CT using enteric contrast material with that of CT not using enteric contrast material in penetrating traumatic abdominopelvic injury in adults. EVIDENCE ACQUISITION. A protocol was registered a priori (PROSPERO CRD42019139613). MEDLINE and EMBASE databases were searched until June 25, 2019. Studies were included that evaluated the diagnostic accuracy of abdominopelvic CT either with or without enteric (oral and/or rectal) contrast material in patients presenting with penetrating traumatic injury. Relevant study data metrics and risk of bias were assessed. Bivariate random-effects meta-analyses and meta-regression modeling were performed to assess and compare diagnostic accuracies. EVIDENCE SYNTHESIS. From an initial sample of 829 studies, 12 studies were included that reported on 1287 patients with penetrating injury (389 with confirmed bowel, mesenteric, or other abdominopelvic organ injury). The enteric contrast material group (seven studies; 506 patients; 124 patients with confirmed penetrating injury) showed a sensitivity of 83.8% (95% CI, 73.7-90.5%) and specificity of 93.8% (95% CI, 83.6-97.8%). The group without enteric contrast administration (six studies; 781 patients; 265 patients with confirmed penetrating injury) showed a sensitivity of 93.0% (95% CI, 86.8-96.4%) and a specificity of 90.3% (95% CI, 81.4-95.2%). No statistically significant difference was identified for sensitivity (p = .07) or specificity (p = .37) between the groups with and without enteric contrast material according to meta-regression. Nine of 12 studies showed risk of bias in at least one QUADAS-2 domain (most frequently limited reporting of blinding of radiologists or lack of blinding of radiologists, insufficient clinical follow-up for the reference standard, and limited reporting of sampling methods). CONCLUSION. The use of enteric contrast material for CT does not provide a significant diagnostic benefit for penetrating traumatic injury. CLINICAL IMPACT. Eliminating enteric contrast administration for CT in penetrating traumatic injury can prevent delays in imaging and surgery and reduce cost.

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
Here in Canada, we often think of gun violence as confined to conflict zones, terrorism, and more of a problem for our southern neighbor. However, in recent years, it has also become a Canadian problem with increased gun violence related to criminal activity presenting in daily practice. Radiologists play a critical role in the evaluation of ballistic trauma and must therefore be familiar with both the common and uncommon patterns of ballistic injury. In this article, we review the mechanisms of ballistic trauma as well as their resultant injury patterns in order to guide image interpretation.

Abstract
Purpose: This study aims to evaluate the overall diagnostic accuracy of preoperative multidetector computed tomography (MDCT) in penetrating abdominal and pelvic injuries (PAPI). Method and Materials: We used our hospitals’ trauma registry to retrospectively identify patients with PAPI from January 1, 2006, to December 31, 2016. Only patients who had a 64-MDCT scan at presentation and subsequently underwent laparotomy or laparoscopy were included in our study cohort. Each finding noted on MDCT was rated using a 5-point scale to indicate certainty of injury, with a score of 0 being definitive. Using surgical findings as the gold standard, the accuracy of radiology reports was analyzed in 2 ways. A κ statistic was calculated to evaluate each pair of values for absolute agreement, and ratings for all organ systems were analyzed using a repeated measures analysis of variance (ANOVA) to determine whether radiology and surgical findings were similar enough to be clinically meaningful. Qualitative review of the radiology and surgical reports focused on the gastrointestinal (GI) tract was conducted. Results: Our cohort consisted of 38 males and 4 females with a median age of 29 years and a median injury severity score of 15.6. For this study, 12 different organ groups were categorized and analyzed. Of those organ groups, absolute agreement between MDCT and surgical findings was found only for liver and spleen (κ values ranging from 0.2 to 0.5). Additionally, the ANOVA revealed an interaction between finding type and organ system ( F 1, 33 = 7.4, P < .001). The most clinically significant discrepancies between MDCT and surgical findings were for gallbladder, bowel, mesenteric, and diaphragmatic injuries. Qualitative review of the GI tract revealed that radiologists can detect significant findings such as presence of injury, however, localization and extent of injury pose a challenge. Conclusion: The detection of clinically significant injuries to solid organs in trauma patients with PAPI on 64-MDCT is adequate. However, detection of injury to the remaining organ groups on MDCT, especially bowel, mesentery, and diaphragm, remains a challenge.

Abstract
AIM To assess the accuracy, sensitivity, and specificity of multidetector computed tomography (MDCT) findings by comparing the locations of free air in the abdomen and imaging findings with the site of gastrointestinal perforation. MATERIALS AND METHODS Ninety-three patients with acute abdominal pain who visited the emergency department between January 2015 and October 2018 were included in the study. There were 59 male and 34 female patients with a mean age of 50.5 years. The site of perforation was based on surgical findings in all cases. RESULTS Among specific air distributions, periportal free air and subphrenic free air were statistically significant in differentiating upper gastrointestinal tract perforation. Whereas free air in the minor pelvis, right lower quadrant free air, left lower quadrant free air, and air in the mesentery were statistically significant in differentiation of lower gastrointestinal tract perforation. CONCLUSION Multidetector findings may help to predict the site of gastrointestinal perforation, which would change the treatment plan.

Abstract
BACKGROUND The practice of marking gunshot wounds and obtaining X-rays (XRs) has been performed to determine the trajectory of missiles to help identify internal injuries. We hypothesized that surgeons would have poor accuracy in predicting injuries and that X-rays do not alter the clinical decision. METHODS We developed a 50-patient (89 injury sites) PowerPoint survey based on cases seen at our level 1 trauma center from 2012 to 2014. Images of a silhouetted BodyMan (BM) with wounds marked, XRs, and vital signs (VSs) were shown in series for 20 s each. Surgeons were asked to record which organs they thought could be injured and to document their clinical decision. Data were analyzed to determine the inter-rater reliability (agreement, intraclass correlation coefficient [ICC]) for each mode of clinical information (BM, XR, VS). Predicted versus actual injuries were compared using absolute agreements. RESULTS Ten surgeons completed the survey. We found that no single piece of information was helpful in allowing the surgeon to accurately predict injuries. Pulmonary injury had the highest agreement among all injuries (ICC = 0.727). VSs had the highest ICC in determining the clinical plan for the patient (ICC = 0.342), whereas both BM and XR had low ICCs (0.162 and 0.183, respectively). CONCLUSIONS We found that marking wounds and obtaining X-rays, other than a chest X-ray, did not result in accuracy in predicting injury nor alter the clinical decision. VSs were the only piece of information found significant in determining clinical management. We conclude that marking wounds for X-rays is an unnecessary step during the initial resuscitation of patients with gunshot wounds.

Abstract
A broad spectrum of pathology affects the rectum, anus, and perineum, and multiple imaging modalities are complementary to physical examination for assessment and treatment planning. In this pictorial essay, correlative imaging, endoscopic, pathologic, and operative images are presented for a range of rectal, perirectal, and perineal disease processes, including infectious/inflammatory, traumatic, congenital/developmental, vascular, and miscellaneous conditions. Key anatomic and surgical concepts are discussed, including radiological information pertinent for surgical planning, and current operative approaches of these anatomic spaces to assist radiologists in comprehensive reporting for gastroenterologists and surgeons.

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
BACKGROUND This is a retrospective review of prospectively collected data on our hospital, a Level 1 trauma centre, where stable patients with single abdominal stab wounds are considered for non-operative (conservative) management if they fulfil the criteria with the aid of computed tomography. The aim is to review our current approach in managing these patients. METHODS Patients' data were obtained from January 2005 to June 2016. All injuries classed as assault or self-harm by sharp object in Injury Severity Score body region 4 were included. Patients were excluded from this study if they had haemodynamic instability, peritonism, significant findings on computed tomography, intoxicated, sustained head injury, sedated and intubated or evisceration of bowel, impalement of the stabbed object, potential thoraco-abdominal injury and multiple stab wounds. The patients were divided into non-operative and delayed operative groups for analysis. RESULTS One hundred and sixty-six of the 313 patients who presented with abdominal stab wounds matched our criteria. One hundred and sixty-three patients (98.2%) from the non-operative group were discharged without complications following period of observation, while three patients underwent operative intervention following trial of non-operative management. The mean length of stay for the successful non-operative group and the group which required delayed operative intervention were 2.8 and 6 days, respectively. No morbidity or mortality was recorded in either group. CONCLUSION Our observational study showed that in a Level 1 trauma centre, patients with single anterior abdominal stab wound and normal vital signs can potentially be safely managed with non-operative approach provided that these patients are cooperative for close observation.

Abstract
OBJECTIVE Many centers advocate use of triple-contrast (IV, oral, and rectal) CT for assessing hemodynamically stable patients with penetrating abdominopelvic trauma. Enteric contrast material has several disadvantages, leading our practice to pursue use of single-contrast (IV) CT. We conducted a retrospective review of electronic medical records at our institution to assess the accuracy of single-contrast CT for diagnosing bowel injuries in cases of penetrating abdominopelvic trauma. MATERIALS AND METHODS We retrospectively reviewed patients who presented to our emergency department between January 1, 2004, and March 1, 2014, with penetrating abdominopelvic trauma, underwent an abdominopelvic CT, and had surgery performed thereafter. We reviewed pertinent emergency department records for details regarding the site of injury, the number of injuries per patient, and the type of weapon used. We correlated CT reports with operative notes for presence and sites of bowel injury. RESULTS A total of 274 patients (median age, 27 years old) met our inclusion criteria; 77% had sustained gunshot wounds (GSWs). CT showed bowel injury in 173 cases; surgery revealed bowel injury in 162 cases. CT had 142 true-positive, 31 false-positive, 81 true-negative, and 20 false-negative cases, resulting in sensitivity of 88%, specificity of 72%, positive predictive value of 82%, and negative predictive value of 80% for detecting bowel injuries. CT had the highest sensitivity and specificity in patients with multiple GSWs (94% and 79%, respectively) and those with injuries to the stomach and rectum. CONCLUSION Single-contrast CT can show bowel injuries in patients with penetrating abdominopelvic trauma with accuracy comparable with that reported for triple-contrast CT.

Abstract
Iatrogenic colonoscopy perforation (ICP) is a severe complication that can occur during both diagnostic and therapeutic procedures. Although 45–60% of ICPs are diagnosed by the endoscopist while performing the colonoscopy, many ICPs are not immediately recognized but are instead suspected on the basis of clinical signs and symptoms that occur after the endoscopic procedure. There are three main therapeutic options for ICPs: endoscopic repair, conservative therapy, and surgery. The therapeutic approach must vary based on the setting of the diagnosis (intra- or post-colonoscopy), the type of ICP, the characteristics and general status of the patient, the operator’s level of experience, and surgical device availability. Although ICPs have been the focus of numerous publications, no guidelines have been created to standardize the management of ICPs. The aim of this article is to present the World Society of Emergency Surgery (WSES) guidelines for the management of ICP, which are intended to be used as a tool to promote global standards of care in case of ICP. These guidelines are not meant to substitute providers’ clinical judgment for individual patients, and they may need to be modified based on the medical team’s level of experience and the availability of local resources.

Abstract
PURPOSE Nonoperative management (NOM) of gunshot liver injuries (GLI) is infrequently practiced. The aim of this study was to assess the safety of selective NOM of GLI. METHODS A prospective, protocol-driven study, which included patients with GLI admitted to a level 1 trauma center, was conducted over a 52-month period. Stable patients without peritonism or sustained hypotension with right-sided thoracoabdominal (RTA) and right upper quadrant (RUQ), penetrating wounds with or without localized RUQ tenderness, underwent contrasted abdominal CT scan to determine the trajectory and organ injury. Patients with established liver and/or kidney injuries, without the evidence of hollow viscus injury, were observed with serial clinical examinations. Outcome parameters included the need for delayed laparotomy, complications, the length of hospital stay and survival. RESULTS During the study period, 54 (28.3%) patients of a cohort of 191 patients with GLI were selected for NOM of hemodynamic stability, the absence of peritonism and CT imaging. The average Revised Trauma Score (RTS) and Injury Severity Score (ISS) were 7.841 and 25 (range 4-50), respectively. 21 (39%) patients had simple (Grades I and II) and 33 (61%) patients sustained complex (Grades III to V) liver injuries. Accompanying injuries included 12 (22.2%) kidney, 43 (79.6%) diaphragm, 20 (37.0%) pulmonary contusion, 38 (70.4%) hemothoraces, and 24 (44.4%) rib fractures. Three patients required delayed laparotomy resulting in an overall success of NOM of 94.4%. Complications included: liver abscess (1), biliary fistula (5), intrahepatic A-V fistula (1) and hospital-acquired pneumonia (3). The overall median hospital stay was 6 (IQR 4-11) days, with no deaths. CONCLUSION The NOM of carefully selected patients with GLI is safe and associated with minimal morbidity.

Abstract
Background To be a level I trauma center in the Netherlands a computed tomography (CT) scanner in the emergency department (ED) is considered desirable, as it is presumed that this optimizes the diagnostic process and that therapy can be directed based on these findings. Aim of this study was to assess the effects of implementing a CT scanner in the ED on outcomes in patients with penetrating injuries. Methods In this retrospective descriptive study, patients with penetrating injuries (shot and/or stab wounds), presented between 2000 and 2014 were analysed using the hospital’s electronic database, and data from the West Netherlands trauma registry and the financial department. Results 405 patients were included: performing a CT scan upon arrival increased significantly from 26.7 to 67.0% (p = 0.00) after implementation of a CT scanner in the ED, with the mean cost of a CT being 96.85 euros. Overall mortality decreased from 6.9 to 3.7%, although not statistically significant. Intensive care unit admission (ICU-admission) and median hospital length of stay (H-LOS) decreased from 30.9 to 24.5% resp. 3.2 to 1.8 days (p ≤ 0.05). Overall mortality, adjusted for injury severity score (ISS), revised trauma score (RTS), and types of injuries, did not change significantly. Conclusion Patients with penetrating injuries more often received a CT scan on admission after implementation of a CT scanner in the ED. Early CT scanning is useful since it significantly reduces ICU-admissions and decreases H-LOS. It is a cheap and non-invasive diagnostic tool with significant clinical impact, resulting in directed treatment, and improvement of outcomes.

Abstract
INTRODUCTION Traumatic injuries to the lower gastrointestinal tract (rectum and anus) have been largely reported in the military setting with sparse publications from the civilian setting. Additionally, there remains a lack of international consensus regarding definitive treatment pathways. This systematic review aimed to assess the current literature and propose a standardised treatment algorithm to aid management in the civilian setting. METHODS A systematic review of available literature from 1999 to 2016 that was performed. Primary endpoints were the assessment and surgical management of reported rectal and anal trauma. RESULTS Seven studies were included in this review, reporting on 1255 patients. 96.3% had rectal trauma and 3.7% had anal trauma. Gunshot wounds are the most common mechanism of injury (46.9%). The overwhelming majority of injuries occurred in males (>85%) and were associated with other pelvic injuries. Surgical management has substantially evolved over the last five decades, with no clear consensus on best management strategies. CONCLUSION There remains significant international discrepancy regarding the management of penetrating trauma to the rectum. Key management principals include the varying use of the direct primary closure, faecal diversion, pre-sacral drainage and/or distal rectal washout (rarely used). To date, there is sparse evidence regarding the management of penetrating anal trauma.

Abstract
BACKGROUND The goal of conservative management (CM) of penetrating abdominal trauma is to avoid nontherapeutic laparotomies while identifying injuries early. Factors that may predict CM failure are not well established, and the experience of CM has not been well described in the Canadian context. METHODS We searched a Canadian level 1 trauma centre database for all penetrating abdominal traumas treated between 2004 and 2014. Hemodynamically stable patients without peritonitis and without clear indications for immediate surgery were considered potential candidates for CM, and were included in the study. We compared those who were managed with CM with those who underwent immediate operative management (OM). Outcomes included mortality and length of stay (LOS). Further analysis was performed to identify predictors of CM failure. RESULTS A total of 72 patients with penetrating abdominal trauma were classified as potential candidates for CM. Ten patients were managed with OM, and 62 with CM, with 9 (14.5%) ultimately failing CM and requiring laparotomy. The OM and CM groups were similar in terms of age, sex, injury severity, mechanism and number of injuries. There were no deaths in either group. The LOS in the intensive care (ICU)/trauma unit was 4.8 ± 3.2 days in the OM group and 2.9 ± 2.6 days in the CM group (p = 0.039). The only predictor for CM failure was intra-abdominal fluid on computed tomography (CT) scan (odds ratio 5.3, 95% confidence interval 1.01-28.19). CONCLUSION In select patients with penetrating abdominal trauma, CM is safe and results in a reduced LOS in the ICU/trauma unit of 1.9 days. Fluid on CT scan is a predictor for failure.

Are We Missing Traumatic Bowel and Mesenteric Injuries? Can Assoc Radiol J 2016; 67:420-425.

Abstract
Purpose Traumatic bowel and mesenteric injury (TBMI), although an uncommon entity, can be lethal if not detected and treated in a timely manner. The purpose of our study was to evaluate the diagnostic accuracy of 64-slice multidetector computed tomography (MDCT) for the detection of TBMI in patients at our level 1 trauma centre. Methods We used our hospital's trauma registry to identify patients with a diagnosis of TBMI from January 1, 2006, to June 30, 2013. Only patients who had a 64-slice MDCT scan at presentation and subsequently underwent laparotomy or laparoscopy were included in the study cohort. Using the surgical findings as the gold standard, the accuracy of prospective radiology reports was analyzed. Results Of the 4781 trauma patients who presented to our institution, 44 (0.92%) had surgically proven TBMI. Twenty-two of 44 were excluded as they did not have MDCT before surgery. The study cohort consisted of 14 males and 8 females with a median age of 41.5 years and a median injury severity score of 27. In total 17 of 22 had blunt trauma and 5 of 22 had penetrating injury. A correct preoperative imaging diagnosis of TBMI was made in 14 of 22 of patients. The overall sensitivity of the radiology reports was 63.6% (95% confidence interval [CI]: 41%-82%), specificity was 79.6% (95% CI: 67%-89%), PPV was 53.9% (95% CI: 33%-73%), and the NPV was 85.5% (95% CI: 73%-94%). Accuracy was calculated at 75.3%. However, only 59% (10 of 17) of patients with blunt injury had a correct preoperative diagnosis. Review of the findings demonstrated that majority of patients with missed blunt TBMI (5 of 7) demonstrated only indirect signs of injury. Conclusion The detection of TBMI in trauma patients on 64-slice MDCT can be improved, especially in patients presenting with blunt injury. Missed cases in this population occurred because the possibility of TBMI was not considered despite the presence of indirect imaging signs. The prospective diagnosis of TBMI remains challenging despite advances in CT technology and widespread use of 64-slice MDCT.

Abstract
The management of gunshot wounds of the abdomen and extremities is evolving with centres who treat large volumes of such injuries tending to the application of a policy of selective non-operative management. This article discusses the management of gunshot wounds to the abdomen and extremities and reviews the evidence supporting these changing practices. Special situations such as wounding by shotguns or air rifles are also examined as are the special considerations needed when dealing with the gunshot injured pregnant women or in a child.

Abstract
The use of computed tomography (CT) for hemodynamically stable victims of penetrating torso trauma continues to increase but remains less singular to the work-up than in blunt trauma. Research in this area has focused on the incremental benefits of CT within the context of evolving diagnostic algorithms and in conjunction with techniques such as laparoscopy, endoscopy, and angiographic intervention. This review centers on the current state of multidetector CT as a triage tool for penetrating torso trauma and the primacy of trajectory evaluation in diagnosis, while emphasizing diagnostic challenges that have lingered despite tremendous technological advances since CT was first used in this setting 3 decades ago. As treatment strategies have also changed considerably over the years in parallel with advances in CT, current management implications of organ-specific injuries depicted at multidetector CT are also discussed.

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
Gunshot injuries occur when someone is shot by a bullet or other sort of projectile from a firearm. Wounds are generally classified as low velocity (less than 609.6m/s) or high velocity (more than 609.6m/s). Those with higher velocity may be expected, on this basis, to dissipate more energy into surrounding tissue as they are slow and cause more tissue damage, but this is only a very approximate guide. However, these terms can be misleading; more important than velocity is the efficiency of energy transfer, which is dependent on the physical characteristics of the projectile, as well as the kinetic energy, stability, entrance profile and path traveled through the body, and the biological characteristics of the tissues injured. Hemodynamically stable patients and patients who stabilized after simple immediate resuscitation were evaluated with a careful history and physical examination. A routine x-ray is performed in patients with gunshot wounds. Indication for total body computed tomography (CT) is based on the presence of signs and symptoms of vascular damage at clinical examination. Patients are immediately transferred in the operating room for surgery if more serious injuries that require immediate surgical care are not diagnosed, or hemostasis may be preliminary reached in the emergency room. Hemodynamically stable patients with no history and clinical examination showing suspected vascular damage are allowed in the radiology department for obtaining a total body CT scan with intravenous contrast medium and then transferred to the surgical ward trauma for observation. After 24 hours without the complications, patient can be discharged. CT is the procedure of choice to identify hemorrhage, air, bullet, bone fragments, hemothorax, nerve lesion, musculoskeletal lesions, and vessels injuries and is useful for assessing medicolegal aspects as trajectory and the anatomical structures at risk.

Abstract
Unlike anterior stab wounds (SW), in which local exploration may direct management, posterior SW can be challenging to evaluate. Traditional triple contrast computed tomography (CT) imaging is cumbersome and technician-dependent. The present study examines the role of CT tractography as a strategy to manage select patients with back and flank SW. Hemodynamically stable patients with back and flank SW were studied. After resuscitation, Betadine- or Visipaque®-soaked sterile sponges were inserted into each SW for the estimated depth of the wound. Patients underwent abdominal helical CT scanning, including intravenous contrast, as the sole abdominal imaging study. Images were reviewed by an attending radiologist and trauma surgeon. The tractogram was evaluated to determine SW trajectory and injury to intra- or retroperitoneal organs, vascular structures, the diaphragm, and the urinary tract. Complete patient demographics including operative management and injuries were collected. Forty-one patients underwent CT tractography. In 11 patients, tractography detected violation of the intra- or retroperitoneal cavity leading to operative exploration. Injuries detected included: the spleen (two), colon (one), colonic mesentery (one), kidney (kidney), diaphragm (kidney), pneumothorax (seven), hemothorax (two), iliac artery (one), and traumatic abdominal wall hernia (two). In all patients, none had negative CT findings that failed observation. In this series, CT tractography is a safe and effective imaging strategy to evaluate posterior torso SW. It is unknown whether CT tractography is superior to traditional imaging modalities. Other uses for CT tractography may include determining trajectory from missile wounds and tangential penetrating injuries.

Selective non-operative management of civilian gunshot wounds to the abdomen: a systematic review of the evidence. Injury 2014; 45:659-66.

Abstract
BACKGROUND Selective non-operative management (SNOM) of penetrating abdominal wounds has become increasingly common in the past two or three decades and is now accepted as routine management for stab wounds. Gunshot wounds are more frequently managed with mandatory laparotomy but recently SNOM has been successfully applied. This review systematically appraises the evidence behind SNOM for civilian abdominal gunshot wounds. METHODS A Medline search from 1990 to present identified civilian studies examining success rates for SNOM of abdominal gunshot wounds. Case reports, editorials and abstracts were excluded. All other studies meeting the inclusion criteria of reporting the success rate of non-operative management of abdominal gunshot wounds were analysed. RESULTS Sixteen prospective and six retrospective studies met the inclusion criteria, including 18,602 patients with abdominal gunshot wounds. 32.2% (n=6072) of patients were initially managed non-operatively and 15.5% (n=943) required a delayed laparotomy. The presence of haemodynamic instability, peritonitis, GI bleeding or any co-existing pathology that prevented frequent serial examination of the abdomen from being performed were indications for immediate laparotomy in all studies. Delayed laparotomy results in similar outcomes to those in patients subjected to immediate laparotomy. Implementation of SNOM reduces the rates of negative and non-therapeutic laparotomies and reduces overall length of stay. CONCLUSIONS SNOM can be safely applied to some civilian patients with abdominal gunshot wounds and reduces the rates of negative or non-therapeutic laparotomy. Patients who require delayed laparotomy have similar rates of morbidity and mortality and similar length of stay to those patients who undergo immediate laparotomy.

Abstract
OBJECTIVES To evaluate multidetector computed tomography (MDCT) for the prediction of perforation site according to each gastrointestinal (GI) tract site and elapsed time. METHODS One hundred and sixty-eight patients who underwent MDCT before laparotomy for GI tract perforation were enrolled and allocated to an early or late lapse group based on an elapsed time of 7 h. Two reviewers independently evaluated the perforation site and assessed the following CT findings: free air location, mottled extraluminal air bubbles, focal bowel wall discontinuity, segmental bowel wall thickening, perivisceral fat stranding and localised fluid collection. RESULTS The overall diagnostic accuracy was 91.07 % and 91.67 % for reviewers 1 and 2, respectively, with excellent agreement (kappa 0.86). Accuracies (98.97 % and 97.94 %) and agreements (kappa 0.894) for stomach and duodenum perforation were higher than for other perforation sites. Strong predictors of perforation at each site were: focal bowel wall discontinuity for stomach, duodenal bulb and left colon, mottled extraluminal air bubbles for retroperitoneal duodenum and right colon, and segmental bowel wall thickening for small bowel. The diagnostic accuracy was not different between the early- and late-lapse groups. CONCLUSIONS MDCT can accurately predict upper GI tract perforation with high reliability. Elapsed time did not affect the accuracy of perforation site prediction. KEY POINTS Perforation of the stomach and duodenum can be accurately predicted with MDCT. Knowledge of CT findings predicting perforation site can improve diagnostic accuracy. Elapsed time does not significantly affect accuracy in predicting perforation sites.

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
The authors discuss the evolution of the evaluation and management of colonic trauma, as well as the debate regarding primary repair versus fecal diversion. Their evidence-based review covers diagnosis, management, surgical approaches, and perioperative care of patients with colon-related trauma. The management of traumatic colon injuries has evolved significantly over the past 50 years; here the authors describe a practical approach to the treatment and management of traumatic injuries to the colon based on the most current research. However, management of traumatic colon injuries remains a challenge and continues to be associated with significant morbidity. Familiarity with the different methods to the approach and management of colonic injuries will allow surgeons to minimize unnecessary complications and mortality.

Abstract
Rectal trauma is associated with high rates of morbidity and mortality and generally affects young males due to its aetiology of violent crime and vehicular collision. Historically, management has followed principles derived from military practice, with faecal diversion, pre-sacral drainage and distal washout being mandatory. Civilian trauma studies examining management of colon and rectum injuries from the early 1950s identified major differences in the level of energy transfer between civilian and military wounds, given that the vast majority are penetrating in nature. This led to a re-evaluation of the necessity for these interventions for all rectal injuries. Current management depends on whether the injury is intra- or extraperitoneal, with those above the peritoneal reflection being readily accessible and amenable to treatment as for colon injury. Extraperitoneal injuries remain difficult to access and direct repair is usually impossible; the mainstay of treatment in most instances remains faecal diversion. The role of pre-sacral drainage and distal washout remains contentious in the realms of civilian rectal injury but retains a place in battlefield or other high-energy transfer rectal injuries where aggressive early management reduces septic complications. This article reviews the historical and current evidence for the management of both civilian and military extraperitoneal rectal injuries.

Abstract
INTRODUCTION The purpose of this study was to evaluate the accuracy of multidetector computed tomography (MDCT) for locating the site of gastrointestinal tract perforations and to determine the most predictive signs in this diagnosis. MATERIAL AND METHODS A total of 98 patients with pneumoperitoneum on MDCT were retrospectively analysed. Two experienced radiologists reviewed the presence or absence of direct signs (extravasation of oral contrast, focal defect in the bowel wall, focal defect with multiplanar reformations images) and indirect signs (free air in supramesocolic, inframesocolic, supramesocolic and inframesocolic compartments, concentration of extraluminal air bubbles adjacent to the bowel wall, extraluminal fluid, segmental bowel-wall thickening, perivisceral fat stranding, abscess) to identify the site of the perforation. The Kappa index was evaluated between radiologists to determine the site of perforation and for each predictive sign, as well as Kappa index between the site of perforation detected with MDCT and the site proven at surgery. The frequency, sensitivity, specificity and positive and negative predictive value (PPV and NPV, respectively) were calculated. RESULTS The perforation site was identified correctly in 80.4% of cases. Kappa index between radiologists to identify the site was excellent (0.919), varying between 0.5-1.0 for each radiological sign. The most frequent site of perforation at surgery (33.7%) and in MDCT (40.82%) was the sigmoid colon/rectum. Concentration of extraluminal air bubbles adjacent to the bowel wall was the most sensitive (91%) sign and "segmental bowel-wall thickening" had the highest PPV (90%). CONCLUSION MDCT is useful for locating the site of GI perforation, with a high sensitivity (80%) and an excellent agreement between radiologists.

Abstract
BACKGROUND The treatment of traumatic injuries to the colon and rectum is often driven by dogma, despite the presence of evidence suggesting alternative methods of care. OBJECTIVE This is an evidence-based review, in the format of a review article, to determine the ideal treatment of noniatrogenic traumatic injuries to the colon and rectum to improve the care provided to this group of patients. Recommendations and treatment algorithms were based on consensus conclusions of the data. DATA SOURCES A search of MEDLINE, PubMed, and the Cochrane Database of Collected Reviews was performed from 1965 through December 2010. STUDY SELECTION Authors independently reviewed selected abstracts to determine their scientific merit and relevance based on key-word combinations regarding colorectal trauma. A directed search of the embedded references from the primary articles was also performed in select circumstances. We then performed a complete evaluation of 108 articles and 3 additional abstracts. MAIN OUTCOME MEASURES The main outcomes were morbidity, mortality, and colostomy rates. RESULTS Evidence-based recommendations and algorithms are presented for the management of traumatic colorectal injuries. LIMITATIONS Level I and II evidence was limited. CONCLUSIONS Colorectal injuries remain a challenging clinical entity associated with significant morbidity. Familiarity with the different methods to approach and manage these injuries, including "damage control" tactics when necessary, will allow surgeons to minimize unnecessary complications and mortality.

Abstract
INTRODUCTION Surgical decision-making in torso trauma is complex. This paper looks at the role of the computed tomography (CT) scan in this decision-making process. PATIENTS AND METHODS Patients with significant torso trauma (high velocity gunshot wound [HVGSW], blast, stab) admitted to a military role 2 (enhanced) hospital facility during a 7-week period of Operation HERRICK 9 (Afghanistan, October to November 2008) are reported. The management of those patients undergoing a CT scan as part of the decision-making process at the time of admission is discussed. RESULTS Twenty eight patients with significant torso trauma were admitted to the facility during the study period; HVGSW (n = 15), blast (n = 9), stab (n = 4). Thirteen patients underwent a CT scan as part of the surgical decision-making process; HVGSW (n = 5), blast (n = 8). Imaging confirmed torso integrity in 12 patients, one of whom subsequently had a laparotomy for vascular control for on-table haemorrhage during lower limb surgery. One patient had a confirmed thoraco-abdominal injury, which was treated conservatively with tube thoracostomy and 'active observation'. CONCLUSIONS A CT scan formed part of the surgical decision-making process in about half of the patients admitted with significant torso trauma, and helped prevent unnecessary laparotomy in this forward military environment. Those patients with a blast injury were more likely to undergo CT scanning than those where the mechanism of injury was a HVGSW.

Abstract
This review discusses the incidence, risk factors, management and outcome of colonoscopic perforation (CP). The incidence of CP ranges from 0.016% to 0.2% following diagnostic colonoscopies and could be up to 5% following some colonoscopic interventions. The perforations are frequently related to therapeutic colonoscopies and are associated with patients of advanced age or with multiple comorbidities. Management of CP is mainly based on patients’ clinical grounds and their underlying colorectal diseases. Current therapeutic approaches include conservative management (bowel rest plus the administration of broad-spectrum antibiotics), endoscopic management, and operative management (open or laparoscopic approach). The applications of each treatment are discussed. Overall outcomes of patients with CP are also addressed.

Single-contrast computed tomography for the triage of patients with penetrating torso trauma. ACTA ACUST UNITED AC 2009; 67:583-8.

Abstract
BACKGROUND We have used single-contrast (intravenous contrast only) computed tomography (SCCT) for triaging hemodynamically stable patients with penetrating torso trauma. We hypothesized that SCCT safely determines the need for operative exploration. Furthermore, trauma surgeons without specialized training in body imaging can accurately apply this modality. METHODS We retrospectively reviewed the records of patients with penetrating torso injuries at a university-based urban trauma center to establish the accuracy of SCCT in determining the need for exploratory laparotomy. The scan was considered positive or negative with respect to the need for exploratory laparotomy as documented by the attending surgeon, who may have considered the read of the on call radiologist if available. In a separate study, four trauma surgeons independently reviewed 42 SCCT scans to establish whether the scans alone could be used to determine whether operative exploration was necessary. RESULTS Between 1997 and 2008, 306 hemodynamically stable patients with penetrating torso trauma were triaged by SCCT. Overall, SCCT predicted the need for laparotomy with 98% sensitivity and 90% specificity. The positive predictive value was 84% and the negative predictive value (NPV) was 99%. In the 222 patients with gunshot wounds, SCCT had 100% sensitivity and 100% NPV. In the 84 patients with stab wounds, SCCT had 92% sensitivity and 97% NPV. Trauma surgeon agreement in the retrospective review of 42 computed tomography scans was "nearly perfect": positive predictive value was 93% and NPV was 92% for determining the need for exploratory laparotomy surgery. CONCLUSIONS SCCT is safe and effective for triaging hemodynamically stable patients with penetrating torso trauma. It successfully determined the need for operative intervention with appropriate clinical accuracy without the additional costs, morbidity, and delay of oral and rectal contrast. Trauma surgeons can reproducibly interpret SCCT with high-predictive accuracy as to whether patients with penetrating torso trauma require operative exploration.

Abstract
OBJECTIVE Nonoperative management (NOM) of liver gunshot injuries is yet to gain general acceptance. The aim of this study was to assess the feasibility and safety of selective NOM of liver gunshot injuries. PATIENTS AND METHODS A prospective, protocol-driven study, which included all liver gunshot injuries admitted to a level I trauma center, was conducted over a 4-year period. Patients with right-sided thoracoabdominal, and right upper quadrant gunshot wounds with or without localized right upper quadrant tenderness underwent contrasted abdominal computed tomography scan evaluation to detect the presence of a liver injury. Patients with confirmed liver injuries were observed with serial clinical examinations. Outcome parameters included need for delayed laparotomy, complications, length of hospital stay, and survival. RESULTS During the study period, 63 patients with liver gunshot injuries were selected for NOM. The mean injury severity score was 19.6 (range, 4-34). Simple liver injuries (grades I and II) occurred in 26 (41.3%) patients and complex liver injuries (grades III, IV, and V) occurred in 37 (58.7%) patients. Associated injuries included 14 (22.2%) kidney, 44 (69.8%) diaphragm, 43 (68.3%) lung contusion, 42 (66.7%) hemothorax and/or pneuomothorax, and 21 (33.3%) rib fractures. Five patients required delayed laparotomy resulting in successful NOM rate of 92%. Complications included liver abscess (3), biliary fistula (3), retained hemothorax (4), and nosocomial pneumonia (5). The mean hospital stay was 6.1 (range, 3-23 days). There was no mortality. CONCLUSION The NOM of appropriately selected patients with liver gunshot injuries is feasible, safe, and effective, regardless of the liver injury severity.
