ANZ J Surg 2024; 94:640-647. [PMID: 38263543 DOI: 10.1111/ans.18875] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Revised: 01/08/2024] [Accepted: 01/10/2024] [Indexed: 01/25/2024]
Abstract
BACKGROUNDS This study investigated the incidence of, and mortality and management outcomes following, pneumatosis intestinalis and/or portal venous gas on computed tomography. METHODS A retrospective study of patients identified with pneumatosis intestinalis and/or portal venous gas on computed tomography at a quaternary centre (2013-2021) was performed. Data relating to clinical presentation (including quick sequential organ failure assessment score), co-morbidities (Charlson Comorbidity Index), biochemical data (including peak lactate level), and radiological findings, were obtained. Factors associated with these were assessed by logistic regression. RESULTS From 16 428 scans, 107 (0.65%) demonstrated pneumatosis intestinalis and/or portal venous gas (mean 65.2 years [SD 15.2]; 60 [56%] male). Overall, 37 patients (35%) had both findings present. Thirty-three deaths (31%) were recorded. Fifty-four patients (51%) underwent surgery. Death was associated with quick sequential organ failure assessment score (score 1: OR 5.71, 95% CI 1.31-24.87; score 2: OR 10.00, 95% CI 1.94-51.54), Charlson Comorbidity Index ≥5 (OR 2.86, 95% CI 1.19-6.84), peak lactate ≥2.6 mmol/L (OR 14.53, 95% CI 4.39-48.14), and concomitant pneumatosis intestinalis and portal venous gas (OR 8.25, 95% CI 3.04-22.38). The presence of free peritoneal fluid (OR 3.23, 95% CI 1.44-7.28) or perforated viscus (OR 5.10, 95% CI 1.05-24.85) were the only predictors for surgery. CONCLUSION Pneumatosis intestinalis and portal venous gas are rare findings. Despite traditionally portending a poor prognosis, mortality occurred in only one-third of patients. There were clear indicators of mortality viz. sepsis severity, comorbidities, and concomitant pneumatosis intestinalis and portal venous gas. Factors predicting surgery warrant further investigation.

Abstract
BACKGROUND We recently developed a preliminary predictive model identifying clinical and radiologic factors associated with the need for surgery following blunt abdominal trauma (BAT) in children. Our aim in this study was to further validate the factors in this predictive model in a multi-institutional study. METHODS A retrospective chart review of pediatric patients from five pediatric trauma centers who experienced BAT between 2011 and 2020 was performed. Patients under 18 years of age who had BAT and computed tomography (CT) abdomen imaging were included. Children with evidence of pneumoperitoneum, and hemodynamic instability were excluded. Fisher's exact test was used for statistical analysis of the association between the following risk factors and need for laparotomy: abdominal wall bruising (AWB), abdominal pain/tenderness (APT), thoracolumbar fracture (TLF), presence of free fluid (FF), presence of solid organ injury (SOI). A predictive logistic regression model was then estimated employing these factors. FINDINGS Seven hundred thirty-four patients were identified in this multi-institutional dataset with BAT and abdominal CT imaging, and 726 were included. Of those, 59 underwent surgical intervention (8.8%). Univariate analysis of association between the studied factors and need for surgical management showed that the presence of TLF (p < 0.01), APT (p < 0.01), FF (p < 0.01), and SOI (p < 0.01) were significantly associated. A predictive model was created using the 5 factors resulting in an area under the curve (AUC) of 0.80. For the motor vehicle collisions (MVC) group, only FF, SOI, and TLF are significantly associated with the need for surgical intervention. The AUC for the MVC group was 0.87. CONCLUSIONS A clinical and radiologic prediction rule was validated using a large multi-institutional dataset of pediatric BAT patients, demonstrating a high degree of accuracy in identifying children who underwent surgery. FF, SOI, and TLF are the most important factors associated with the need for surgical intervention. LEVEL OF EVIDENCE Level III.

Abstract
PURPOSE We aimed to identify factors related to delayed intervention in abdominal trauma patients who underwent diagnostic laparoscopy using a nationwide databank. METHODS From 2017 to 2019, abdominal trauma patients who underwent diagnostic laparoscopy were retrospectively evaluated using the Trauma Quality Improvement Program. Patients who underwent delayed interventions after a primary diagnostic laparoscopy were compared with those who did not. Factors associated with poor outcomes that are usually correlated with overlooked injuries and delayed interventions were also analyzed. RESULTS Of the 5221 studied patients, 4682 (89.7%) underwent inspection without any intervention. Only 48 (0.9%) patients underwent delayed interventions after primary laparoscopy. Compared with patients receiving immediate interventions during primary diagnostic laparoscopy, patients receiving delayed interventions were more likely to have small intestine injuries (58.3% vs. 28.3%, p < 0.001). Among patients with hollow viscus injuries, a significantly higher probability of overlooked injuries that required delayed intervention was observed in patients with small intestine injuries (small intestine injury: 16.8%; gastric injury: 2.5%; large intestine injury: 5.2%). However, delayed small intestine repair did not significantly affect the risk of surgical site infection (SSI) (p = 0.249), acute kidney injury (AKI) (p = 0.998), or hospital length of stay (LOS) (p = 0.053). In contrast, significantly positive relationships between delayed large intestine repair and poor outcomes were observed (SSI, odds ratio = 19.544, p = 0.021; AKI, odds ratio = 27.368, p < 0.001; LOS, β = 13.541, p < 0.001). CONCLUSIONS Most examinations and interventions (near 90%) were successful during primary laparoscopy for abdominal trauma patients. Small intestine injuries were easily overlooked. Delayed small intestine repair-related poor outcomes were not observed.

Abstract
Background Racial disparities in outcomes among patients in the United States are widely recognized, but disparities in treatment are less commonly understood. This study is intended to identify treatment disparities in delivery of surgery and time to surgery for diagnoses managed by general surgeons-appendicitis, cholecystitis, gallstone pancreatitis, abdominal wall hernias, intestinal obstructions, and viscus perforations. Methods The National Inpatient Sample (NIS) was used to estimate and analyze disparities in delivery of surgery, type of surgery received, and timing of surgery. Age-adjusted means were compared by race/ethnicity and trends in treatment disparities were evaluated from 1993 to 2017. Linear modeling was used to measure trends in treatment and outcome disparities over time. Mediation analysis was performed to estimate contributions of all available factors to treatment differences. Relationships between treatment disparities and disparities in mortality and length of stay were similarly evaluated. Results Black patients were less likely to receive surgery for appendicitis, cholecystitis, pancreatitis, and hernias, and more likely to receive surgery for obstructions and perforations. Black patients experienced longer wait times prior to surgery, by 0.15 to 1.9 days, depending on the diagnosis. Mediation analysis demonstrated that these disparities are not attributable to the patient factors available in the NIS, and provided some insight into potential contributors to the observed disparities, such as hospital factors and socioeconomic factors. Conclusion Treatment disparities are present even with common indications for surgery, such as appendicitis, cholecystitis, and gallstone pancreatitis. Black patients are less likely to receive surgery with these diagnoses and must wait longer for surgery if it is performed. Surgeons should plan institution-level interventions to measure, explain, and potentially correct treatment disparities.

Abstract
Key Clinical Message Spine surgeons should be aware of the possibility of anterior displacement of the grafted bone during PLIF and the potential for severe complications that may arise because of such displacement so that preparations can be made for a proper response. Abstract We report two cases of anterior displacement of the grafted bone after posterior lumbar interbody fusion (Graphical Abstract A-D). The patients did not require additional surgery. The anterior migration of grafted bone or cage can cause damage to anterior organs and blood vessels. Therefore, a careful surgical procedure is necessary.

Abstract
Background The seatbelt sign (SBS) is a pattern of bruising/contusions on the chest and abdominal wall following motor vehicle collisions. The aim of this analysis is to investigate the influence of time to surgery following identification of the SBS on perioperative outcomes. Methods A retrospective review of the Trauma Quality Improvement Program database from 2017 to 2019 was performed. Patients included in this retrospective analysis were involved in motor vehicle collisions, experienced blunt abdominal trauma, presented with skin abrasions/contusions in the SBS distribution, were hemodynamically stable, and underwent laparotomy. Demographics, vital signs, injury severity score, Glasgow coma scale, preoperative CT scans (P-CT), and time from presentation to surgery were recorded. Time from presentation to surgery was subdivided by data quartiles as immediate (<1.3 h), early (1.3-4 h), and delayed (>4 h). The influence of operative timing on postoperative mortality, hospital length of stay (LOS), intensive care unit (ICU) LOS, and ventilator days was assessed in multivariate analyses. Results A total of 1523 patients were included; 280 underwent immediate, 610 early, and 633 delayed surgery. Patients undergoing surgery in the early and delayed groups who received P-CT scans had shorter mean times to operation (4.52 h vs 5.24 h, p < 0.01). In multivariate analysis, patients who underwent delayed surgery stayed in the hospital 2.5 days longer (p < 0.001), spent 2.8 additional days in the ICU (p < 0.001), and spent 3.75 additional days on a ventilator (p < 0.001) than patients who received early surgery. Within the early and delayed surgical groups, P-CT was associated with lower mortality (OR 0.46 95 % CI 0.24-0.88, p < 0.01) in multivariate analysis. Conclusions Early surgical intervention was associated with improved patient outcomes by reducing hospital and ICU LOS and ventilator days. Conducting P-CT reduced the time to surgery and mortality. Utilization of P-CT for screening hemodynamically stable patients with the SBS upon admission may expedite identification of the potential need for surgical management of abdominal injury.

Abstract
BACKGROUND Previous work demonstrated diagnostic delays in blunt small bowel perforation (SBP) with increased mortality and inability of scans to reliably exclude the diagnosis. We conducted a follow-up multicenter study to determine if these challenges persist 15 years later. METHODS We selected adult cases with blunt injury, International Classification of Diseases, Ninth Revision or current procedural terminology (CPT) indicating small bowel surgery, no other major injury and at least one abdominal computed tomography (CT) within initial 6 hours. Controls had blunt trauma with abdominal CT but not SBP. After institutional review board approval, data from each center were collected and analyzed. RESULTS Data from 39 centers (from October 2013 to September 2015) showed 127,919 trauma admissions and 94,743 activations. Twenty-five centers were Level 1. Centers submitted 77 patients (mean age, 39; male, 68%; mean length of stay, 11.3 days) and 131 controls (mean age, 44; male, 64.9%; length of stay, 3.6 days). Small bowel perforation cases were 0.06% of admissions and 0.08% of activations. Mean time to surgery was 8.7 hours (median, 3.7 hours). Initial CT showed free air in 31 cases (43%) and none in controls. Initial CT was within normal in three cases (4.2%) and 84 controls (64%). Five cases had a second scan; two showed free air (one had an initial normal scan). One death occurred among the patients (mortality, 1.4%; and time to surgery, 16.9 hours). Regression analysis showed sex, abdominal tenderness, distention, peritonitis, bowel wall thickening, free fluid, and contrast extravasation were significantly associated with SBP. CONCLUSIONS Blunt SBP remains relatively uncommon and continues to present a diagnostic challenge. Trauma centers have shortened time to surgery with decreased case mortality. Initial CT scans continue to miss a small number of cases with potentially serious consequences. We recommend (1) intraperitoneal abnormalities on CT scan should always evoke high suspicion and (2) strong consideration of additional diagnostic/therapeutic intervention by 8 hours after arrival in patients who continue to pose a clinical challenge.

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
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
After blunt trauma, certain CT markers, such as free intraperitoneal air, strongly suggest bowel perforation, whereas other markers, including free intraperitoneal fluid without solid organ injury, may be merely suspicious for acute injury. The present study aims to delineate the safety of non-operative management for markers of blunt bowel or mesenteric injury (BBMI) that are suspicious for significant bowel injury after blunt trauma. This was a retrospective review of adult blunt trauma patients with abdominopelvic CT scans on admission to a Level I trauma center between 2012 and 2014. Patients with CT evidence of acute BBMI without solid organ injury were included. The CT markers for BBMI included free intraperitoneal fluid, bowel hematoma, bowel wall thickening, mesenteric edema, hematoma and stranding. Two thousand blunt trauma cases were reviewed, and 94 patients (4.7%) met inclusion criteria. The average Injury Severity Score was 13.6 ± 10.1 and the median hospital stay was four days. The most common finding was free fluid (74 patients, 78.7%). The majority of patients (92, 97.9%) remained asymptomatic or clinically improved without abdominal surgery. After a change in abdominal examination, two patients (2.1%) underwent laparotomy with bowel perforation found in only one patient. Thus, 93 patients did not have a surgically significant injury, indicating that these markers demonstrate 1.1 per cent positive predictive value for bowel perforation. The presence of these markers after blunt trauma does not mandate laparotomy, though it should prompt thorough and continued vigilance toward the abdomen.

Abstract
Small bowel perforation is a unique, serious complication during endometrial biopsy. The authors report a case of a double uterine-ileal perforation totally managed by primary laparoscopic repair. A 63-year-old female was admitted with acute abdomen 2 days after an endometrial curettage. Abdominal X-ray shows signs of pneumoperitoneum. Emergency diagnostic laparoscopy was performed and a uterine-ileal perforation was identified. Repair was accomplished by a totally laparoscopic intracorporeally suturing of the 2 breaches. Postoperative course showed only a delayed ileus and the patient was discharged after 5 days with no complications. When acute abdomen arises following uterine biopsy, a potential iatrogenic intestinal laceration always has to be ruled out. Laparoscopic approach is a quick and safe technique in these cases. Totally laparoscopic primary closure of the iatrogenic ileal laceration may be accomplished with low morbidity.

Abstract
Pelvic fractures can result in life-threatening hemorrhages or other associated injuries. Therefore, computed tomography (CT) scanning plays a key role in the management of pelvic fracture patients. However, CT scanning is utilized as an adjunct in secondary survey according to traditional Advanced Trauma Life Support (ATLS) guidelines, whereas pelvic x-ray is used as a primary tool to evaluate pelvic stability and the necessity of further CT scanning. In the current study, we attempted to evaluate the role of CT scanning in the era of advanced technology. The significance of pelvic stability was also analyzed. From January 2012 to December 2014, the trauma registry and medical records of pelvic fracture patients were retrospectively reviewed. A 64-slice multidetector CT scanner was used in our emergency department as a standard diagnostic tool for evaluating trauma patients. Pelvic x-ray was used as a primary tool for screening pelvic fractures, and pelvic stability was evaluated accordingly. CT scans were performed in patients with unstable pelvic fractures, suspected associated intra-abdominal injuries (IAIs), or other conditions based on the physicians' clinical judgment. The clinical features of patients with stable and unstable pelvic fractures were compared. The patients with stable pelvic fractures were analyzed to determine the characteristics associated with retroperitoneal hemorrhage (RH) or IAIs. Patients with stable pelvic fractures were also compared based on whether they underwent a CT scan. A total of 716 patients were enrolled in this study. There were 533 (74.4%) patients with stable pelvic fractures. Of these patients, there were 66 (12.4%) and 50 (9.4%) patients with associated RH and IAI, respectively. There were no significant differences between the patients with associated RH based on their primary evaluation (vital signs, volume of blood transfusion, and hemoglobin level). Similarly, the demographics and the primary evaluation results (symptoms, coma scale, and white blood cell counts) of the patients with associated IAIs were also not significantly different from the patients without associated IAIs. Furthermore, the time to definitive hemostasis (surgery or angioembolization) was not significantly different between the unstable patients who underwent a CT scan or those who did not.In the management of pelvic fracture patients, the role of pelvic stability is not significant in the evaluation of associated RH or IAI. Routine CT scanning is suggested for pelvic fracture patients because of the rapid scanning time and sufficient information produced.

Unplanned intensive care unit admission following trauma. J Crit Care 2016; 33:174-9. [PMID: 26979911 DOI: 10.1016/j.jcrc.2016.02.012] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2015] [Revised: 01/17/2016] [Accepted: 02/14/2016] [Indexed: 11/22/2022]
Abstract
BACKGROUND The prevalence and outcomes of trauma patients requiring an unplanned return to the intensive care unit (ICU) and those initially admitted to a step-down unit or floor and subsequently upgraded to the ICU, collectively termed unplanned ICU (UP-ICU) admission, are largely unknown. METHODS A retrospective review of the trauma registry of a suburban regional trauma center was conducted for adult patients who were admitted between 2007 and 2013, focusing on patients requiring ICU admission. Prehospital or emergency department intubations and patients undergoing surgery immediately after emergency room evaluation were excluded. RESULTS Of 5411 admissions, there were 212 UP-ICU admissions, 541 planned ICU (PL-ICU) admissions, and 4658 that were never admitted to the ICU (NO-ICU). Of the 212 UP-ICU admits, 19.8% were unplanned readmissions to the ICU. Injury Severity Score was significantly different between PL-ICU (16), UP-ICU (13), and NO-ICU (9) admits. UP-ICU patients had significantly more often major (Abbreviated Injury Score ≥ 3) head/neck injury (46.7%) and abdominal injury (9.0%) than the NO-ICU group (22.5%, 3.4%), but significantly less often head/neck (59.5%) and abdominal injuries (17.9%) than PL-ICU patients. Major chest injury in the UP-ICU group (27.8%) occurred at a statistically comparable rate to PL-ICU group (31.6%) but more often than the NO-ICU group (14.7%). UP-ICU patients also significantly more often underwent major neurosurgical (10.4% vs 0.7%), thoracic (0.9% vs 0.1%), and abdominal surgery (8.5% vs 0.4%) than NO-ICU patients. Meanwhile, the PL-ICU group had statistically comparable rates of neurosurgical (6.8%) and thoracic surgical (0.9%) procedures but lower major abdominal surgery rate (2.0%) than the UP-ICU group. UP-ICU admission occurred at a median of 2 days following admission. UP-ICU median hospital LOS (15 days), need for mechanical ventilation (50.9%), and in-hospital mortality (18.4%) were significantly higher than those in the PL-ICU (9 days, 13.9%, 5.4%) and NO-ICU (5 days, 0%, 0.5%) groups. CONCLUSIONS UP-ICU admission, although infrequent, was associated with significantly greater hospital length of stay, rate of major abdominal surgery, need for mechanical ventilation, and mortality rates than PL-ICU and NO-ICU admission groups.

Abstract
The incidence of small bowel perforation is low but can develop from a variety of causes including Crohn disease, ischemic or bacterial enteritis, diverticulitis, bowel obstruction, volvulus, intussusception, trauma, and ingested foreign bodies. In contrast to gastroduodenal perforation, the amount of extraluminal air in small bowel perforation is small or absent in most cases. This article will illustrate the main aspects of small bowel perforation, focusing on anatomical reasons of radiological findings and in the evaluation of the site of perforation using plain film, ultrasound, and multidetector computed tomography equipments. In particular, the authors highlight the anatomic key notes and the different direct and indirect imaging signs of small bowel perforation.

Concomitant hollow viscus injuries in patients with blunt hepatic and splenic injuries: an analysis of a National Trauma Registry database. Injury 2014; 45:1409-12. [PMID: 24656303 DOI: 10.1016/j.injury.2014.02.027] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2014] [Revised: 02/12/2014] [Accepted: 02/20/2014] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Non-operative management has become the standard approach for treating stable patients sustaining blunt hepatic or splenic injuries in the absence of other indications for laparotomy. The liberal use of computed tomography (CT) has reduced the rate of unnecessary immediate laparotomies; however, due to its limited sensitivity in the diagnosis of hollow viscus injuries (HVI), this may be at the expense of a rise in the incidence of missed HVI. The aim of this study was to assess the incidence of concomitant HVI in blunt trauma patients diagnosed with hepatic and/or splenic injuries, and to evaluate whether a correlation exists between this incidence and the severity of hepatic or splenic injuries. METHODS A retrospective cohort study involving blunt trauma patients with splenic and/or liver injuries, between the years 1998 and 2012 registered in the Israel National Trauma Registry. The association between the presence and severity of splenic and/or liver injuries and the incidence of HVI was examined. RESULTS Of the 57,130 trauma victims identified as suffering from blunt torso injuries, 2335 (4%) sustained hepatic injuries without splenic injuries (H group), 3127 (5.4%) had splenic injuries without hepatic injuries (S group), and 564 (1%) suffered from both hepatic and splenic injuries (H+S group). Overall, 957 patients sustained 1063 HVI. The incidence of HVI among blunt torso trauma victims who sustained neither splenic nor hepatic injuries was 1.5% which is significantly lower than in the S (3.1%), H (3.1%), and H+S (6.7%) groups. In the S group, there was a clear correlation between the severity of the splenic injury and the incidence of HVI. This correlation was not found in the H group. CONCLUSIONS The presence of blunt splenic and/or hepatic injuries predicts a higher incidence of HVI, especially if combined. While in blunt splenic injury patients there is a clear correlation between the incidence of HVI and the severity of splenic injury, such a correlation does not exist in patients with blunt hepatic injury.

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
BACKGROUND Isolated small bowel injury (ISBI) related to abdominal blunt trauma is rare. Timely diagnosis could be difficult, especially in the absence of modern imaging and laparoscopic facilities. The determinants of mortality under such circumstances are unclear. METHODS This study presents twenty three cases of ISBI related to blunt abdominal injury identified between January 2005 and December 2009 in a level III Hospital in Limbe, Cameroon. Data were retrieved from an ongoing prospective study on injuries and augmented by analysis of individual patient's files. We analysed information regarding modalities of diagnosis, delay between injury and diagnosis, operative findings, treatment and outcome. RESULTS The ages of our patients ranged from 7 to 38 years with a mean of 19 years. Thirteen patients were children below the age of 16. The most frequent mechanism of injury was a fall (n=11). Associated lesions were identified in 7 patients. Delay between injury and diagnosis was above 12h in 16 patients. Fifteen cases were admitted with obvious signs of peritonitis. Erect chest X-ray identified a pneumoperitoneum in 11 of the 17 patients for whom it was requested. Most perforations were located in the ileum. A total of 7 complications occurred in 5 patients. These included 4 cases of post-operative peritonitis. Two patients with at least one associated lesion died. CONCLUSION ISBI is seldom suspected. This causes delay in diagnosis and most cases present with a diffuse peritonitis. Early diagnosis and management in low income environment is likely to be improved by a greater awareness of clinicians about this injury, serial clinical assessment and repeated erect chest X-ray, rather than sophisticated tools such as CT scan or laparoscopy.

Abstract
BACKGROUND Despite the availability of more accurate imaging modalities, specifically multidetector computed tomography (MDCT), the diagnosis of non-ischemic (NI-) and ischemic (I-) blunt hollow viscus and mesenteric injury (BHVMI) remains challenging. We hypothesized that BHVMI can be still missed with newer generations of MDCT and that patients with I-BHVMI have a poorer outcome than those with NI-BHVMI. METHODS We performed an eight-year retrospective review at a level 1 trauma center. Ischemic-BHVMI was defined as devascularization confirmed at laparotomy. Non-ischemic-BHVMI included perforation, laceration, and hematoma without devascularization. The sensitivity of each generation of MDCT for BHVMI was calculated. Potential predictors and outcomes of I-BHVMI were compared to the NI-BHVMI group. RESULTS Of 7,875 blunt trauma patients, 67 patients (0.8 %) were included in the BHVMI group; 13 patients did not have any CT findings suggestive of BHVMI (sensitivity 81 %), and 11 of them underwent surgical intervention without delay (<5 h). Newer generations of MDCT were not associated with higher sensitivity. Patients with I-BHVMI had a significantly higher rate of delayed laparotomy ≥ 12 h (23 % versus 2 %; p = 0.01) and a significantly longer length of hospital stay (median 14 versus 9 days; p = 0.02) than those with NI-BHVMI. CONCLUSIONS Even using an advanced imaging technique, the diagnosis of I-BHVMI can be delayed, with significant negative impact on patient outcome.

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
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.

Clinical significance of isolated intraperitoneal fluid on computed tomography in pediatric blunt abdominal trauma. J Pediatr Surg 2009; 44:1242-8.

Abstract
PURPOSE The finding of isolated free intraperitoneal fluid (FIPF) on computed tomography of the abdomen (CTA) in children after blunt trauma is of unclear clinical significance and raises suspicion for a solid or hollow viscus injury. In our institution, pediatric blunt trauma patients presenting with isolated FIPF on CTA who are hemodynamically stable and have no peritoneal signs on initial physical examination (iPE) have been historically approached nonoperatively. We reviewed our level 1 trauma center experience with this subset of the trauma population and sought to (1) justify an initial nonoperative approach and (2) identify early predictors of the eventual need for surgical exploration. METHODS Data on all trauma patients less than 14 years of age admitted to our hospital from 2001 to 2006 after Blunt Abdominal Trauma (BAT) whose screening CTA showed FIPF and no other radiographic signs of solid or hollow viscus injury were retrieved from the local trauma registry. Clinical progress, operative findings, and follow-up were obtained by hospital and office chart review, as well as telephone contact. Mechanism of injury (MOI); Injury Severity Score (ISS); Revised Trauma Score; Pediatric Trauma Score (PTS); the presence of abdominal tenderness or external signs of injury on iPE; and quantity, location, and density of the FIPF were statistically analyzed as possible early predictors of the eventual need for surgical exploration. RESULTS A total of 670 children admitted to our institution after blunt trauma were evaluated with CTA during the time of enrollment. Isolated FIPF was found in 94 individuals (14%). Mean age was 9.7 (+/-SD 3.2) years; 52% were males. Motor vehicle crash was the most common MOI. Mean PTS was 10.6 (+/-SD 1.8). Mean ISS was 10.2 (+/-SD 7.2). Free intraperitoneal fluid was most commonly found in only one intraperitoneal region (93%). Most patients (97%) were discharged home without undergoing a surgical procedure. Three other patients developed peritonitis on serial physical examination and were surgically explored. Hollow viscus injuries were found in 2 of these individuals and treated with primary repair or segmental bowel resection. All surgical patients enjoyed a full recovery, with no postoperative complications. The presence of abdominal tenderness on iPE and the quantity of FIPF on initial CTA were the only studied variables to reach statistical significance as predictors of the eventual need for operative intervention. Follow-up after hospital discharge was obtained in 46.8% (44/94) and averaged 124.9 weeks. CONCLUSION To the best of our knowledge, this is the largest series of pediatric blunt trauma patients with isolated FIPF on CTA ever reported. Our findings justify an initial nonoperative approach for the management of these individuals. Abdominal tenderness on iPE and the quantity of FIPF on initial CTA were predictors of the eventual need for operative intervention.

PURPOSE The objective of this study was to compare patients with "isolated" blunt small bowel injury (SBI) to patients with multiple intra-abdominal injuries and analyze whether delayed laparotomy affected outcome. METHODS Medical records of patients that suffered a blunt SBI between 1994 and 2005 were reviewed. The patients were divided into two groups: those with isolated SBI and those with other associated intra-abdominal injuries ("non-isolated"). The method of diagnosis, time to operation, small bowel Organ Injury Scale (OIS) assessment (grade >or= 2), injury severity score (ISS), morbidity, and mortality were analyzed. RESULTS A total of 90 patients met the inclusion criteria, including 62 (68.9%) isolated cases and 28 (31.1%) non-isolated cases. Isolated cases required more supplementary diagnostic methods than the non-isolated cases. Non-isolated cases had a shorter diagnosis to treatment period (p < .01) and a higher ISS (mean 22.5 vs. 17.2 in "isolated" group). Morbidity (51.6% and 53.6%) and mortality (16.1% and 28.6%) did not differ significantly between the isolated and non-isolated groups. Delays in diagnosis were common in the isolated group, but this did not affect outcome. Patients with associated injuries, and higher ISS, had higher mortality. CONCLUSIONS The presence of associated intra-abdominal injuries significantly affected the presentation and time to diagnosis of patients with SBI, but not morbidity or mortality. Delayed surgical treatment in the isolated cases was not associated with an increased incidence of complications. Patients inflicted with more severe associated injuries were less likely to survive the trauma.

Abstract
OBJETIVO: Os objetivos deste estudo foram avaliar o diagnóstico e o tratamento das lesões de intestino delgado e determinar os fatores que influenciaram a morbimortalidade. MÉTODO: Estudo retrospectivo incluindo 410 pacientes com lesão de intestino delgado operados entre janeiro de 1994 e dezembro de 2004. Os dados coletados incluíram: mecanismo de trauma, métodos diagnósticos, tempo transcorrido até a intervenção cirúrgica, grau das lesões, índices de trauma, conduta cirúrgica (sutura ou ressecção e anastomose), morbidade (especialmente fístula) e mortalidade. A comparação entre os grupos foi feita usando os testes de Fisher e Yates. RESULTADOS: O mecanismo de trauma foi penetrante em 321 pacientes (78,3%) e fechado em 89 (21,7%). Houve mais pacientes tratados cirurgicamente com intervalo maior que 6 horas após o trauma no grupo trauma contuso se comparados com trauma penetrante (p<0,05). Sutura da lesão foi feita em 52,2% dos pacientes e ressecção e anastomose em 46,8%, e ambos procedimentos apresentaram a mesma incidência de fístula (4,7%). A morbidade foi de 35,1%. A incidência de fistula foi maior nos pacientes submetidos à laparotomia com mais de 12 horas após o trauma quando comparados com aqueles operados com menos de 12 horas (8,3% vs. 4,3%; sem diferença estatística), mas isto não foi fator determinante para maior mortalidade. A mortalidade foi de 13,7% e foi relacionada com escores de gravidade mais elevados. CONCLUSÃO: A lesão de intestino delgado é freqüente após o trauma abdominal, sendo mais comum nos traumas penetrantes. O diagnóstico desta lesão após trauma fechado pode ser difícil, com demora para o tratamento cirúrgico. A ocorrência de fistula não esteve relacionada aos seguintes fatores analisados: mecanismo de trauma, tempo transcorrido entre o trauma e a operação, conduta cirúrgica, lesões intra-abdominais associadas ou gravidade das lesões. A mortalidade esteve relacionada com lesões associadas.

Abstract
BACKGROUND The abdomen is routinely considered as a possible source of bleeding in hypotensive and unevaluable blunt multitrauma patients. These patients are often unstable to be transported for abdominal computed tomography (CT). Emerging data on Focused Assessment with Sonography for Trauma (FAST) exam questions its initially reported high accuracy. We hypothesized that Diagnostic Peritoneal Aspiration (DPA), without a full lavage, accurately detects intraperitoneal blood if present in sufficient volume to cause hypotension and warrant emergent operation. METHODS Over 24 months (July 2002-June 2004), 62 severe blunt trauma patients (Injury Severity Score: 32+/-17) with admission systolic blood pressure equal to or less than 90 mmHg were enrolled prospectively. Percutaneous DPA was performed after FAST. Aspiration of any quantity of blood was considered a positive test. Sensitivity and specificity of DPA and FAST were calculated against findings from abdominal CT, laparotomy, or autopsy. RESULTS Twenty-two patients (35%) required emergent laparotomy and 39 (63%) died. DPA was performed in less than 1 min with no complications. Sensitivity and specificity of DPA was 89% and 100%, respectively, whereas for FAST it was 50% and 95%. Two (3%) false negative DPA were recorded; one patient had a minor liver laceration with 250 ml of free blood and the other a leaking retroperitoneal pelvic hematoma in the presence of cirrhosis with 600 ml of bloody ascitic fluid. There were no false positive DPA. Nine (14.5%) false negative and two (3%) false positive FAST were recorded in patients who were found to have at laparotomy 1575+/-1070 ml of hemoperitoneum on average. CONCLUSIONS Percutaneous DPA is accurate, rapid, safe, and superior to FAST for the diagnosis of abdominal blood as the source of hemodynamic instability, requiring emergent surgery, in blunt multitrauma patients.

Abstract
BACKGROUND The prompt detection and accurate localization of abdominal injuries are difficult. Some diagnostic modalities, including laboratory tests, ultrasound, and diagnostic peritoneal lavage (DPL) were used to evaluate patients with blunt abdominal trauma, with various advantages and pitfalls. We aimed to evaluate the risk and benefit of using multidetector computed tomography (MDCT) as an initial assessment tool for proper diagnosis and treatment planning of patients with blunt abdominal trauma. METHODS Two hundred fifty-two patients with blunt abdominal trauma were prospectively enrolled. Multidetector computed tomography was performed during resuscitation. The risk and benefit of using MDCT in the diagnosis and planning of treatment were analyzed. RESULTS The time required for a MDCT examination averaged 10.2 minutes. Of the studies done, 224 revealed abdominal injuries. Of those, 34 were performed in patients with unstable hemodynamic status without adverse effect. Prompt diagnosis and proper treatment were given according to the MDCT findings. A total of 43 (17.1%) MDCTs showed contrast extravasation. Active bleeding was confirmed in all and treated with transarterial embolization (30) or surgery (13). Another 58 patients sustained bowel, mesenteric, or pancreatic injuries (BMPI) necessitating laparotomy. The sensitivity, specificity, and accuracy of MDCT in identifying patients with active bleeding or BMPI were all 100%. CONCLUSIONS Multidetector computed tomography was useful as a second line initial assessment tool to identify injuries and determine treatment planning in blunt abdominal trauma patients. No increased risk was found if the facility is readily available, the protocol is well designed, and the patient is well prepared.

Abstract
CT is the imaging modality of choice to evaluate blunt abdominal trauma. With the advent of multidetector CT (MDCT), scanning times have progressively decreased while image resolution has increased owing to thinner collimation and reduced partial volume and motion artifacts. MDCT also allows high quality two-dimensional and three-dimensional multiplanar reformatted images to be obtained, which aid in the diagnosis of the complex multisystem injuries seen in the trauma patient. This article describes the authors' current imaging protocol with 16-detector MDCT, the spectrum of CT findings seen in patients with blunt abdominal injuries, and the role MDCT has in guiding injury management.

Abstract
PURPOSE Currently, nonoperative management is the procedure of choice for solid organ injury in patients with a blunt abdominal trauma. Missed blunt bowel and mesenteric injuries (BBMIs) are possible because diagnosis is difficult. The aim of our study was to test a new algorithm for BBMI diagnosis using abdominal ultrasonography (AUS), computed tomography (CT), and diagnostic peritoneal lavage (DPL). METHODS We reviewed cases of blunt abdominal injuries over a 10-year period, then we designed an algorithm that was prospectively tested in hemodynamically stable patients over a 2-year period. An abnormal AUS led to helical CT. When the CT showed more than 2 findings suggestive of BBMI, laparotomy was performed. In case of 1 or 2 abnormal CT findings, we performed a DPL and calculated the ratio of white blood cells (WBCs) to red blood cells (RBCs) (WBC/RBC ratio) in the lavage fluid and divided this by the WBC/RBC ratio in peripheral blood. A ratio of 1 or higher was considered positive for BBMI, and a laparotomy was immediately performed. Patients with a ratio of less than 1 were managed nonoperatively. RESULTS In the retrospective study, 26 (1%) of 2126 patients admitted to our trauma center for blunt trauma had a BBMI, including 15 (58%) diagnosed after a median delay of 24 hours. In the prospective study, 531 patients were admitted for blunt trauma with multiple injuries, including 131 with abdominal trauma. Computed tomography was performed in 40 patients. There were 2 criteria or more of BBMI in 1 patient, 0 criteria in 27 patients (with an uneventful follow-up), and 1 or 2 criteria in 12 patients who had DPL with a median ratio of 0.82 (ranges, 0.03-9). Five patients had a ratio of 1 or higher. They underwent immediate laparotomy. In all 5 cases, BBMI was found. The 7 patients who had a ratio of less than 1 were observed in ICU and treated for extra-abdominal injuries. No BBMI injury was missed in these patients. The accuracy of the algorithm was 100% (95% confidence interval, 0.99-1.00). CONCLUSION The proposed algorithm (based on AUS, CT, and DPL) had a high accuracy to diagnose BBMI while requiring the performance of DPL in only a few (2%) patients.

Abstract
PURPOSE The radiological evaluation of patients with blunt abdominal trauma can be done with either ultrasound (US) or computed tomography (CT) with strategies varying considerably among institutions. We evaluated the efficacy of our current strategy in which US is used at our hospital as the primary screening tool for patients with blunt abdominal trauma. METHODS We retrospectively analysed all patients admitted to our hospital with possible blunt abdominal trauma who underwent abdominal US, abdominal CT and/or a laparotomy during the initial trauma assessment from 1998 until 2002 (n = 1149). RESULTS Nine-hundred sixty-one of the 1149 patients had a negative US, of which 922 were true negative, resulting in a negative predictive value of 96%. A CT of the abdomen was performed in 7%. In 1.7% there was delayed diagnosis with no significant additional morbidity. Fourteen of the 103 laparotomies (14%) were non-therapeutic; in 5 of these cases the patients underwent non-therapeutic laparotomy despite the performance of a CT. Seven were emergency operations. CONCLUSIONS In our practice, the use of US for the evaluation of acute blunt abdominal trauma is adequate, with a high negative predictive value, a small number of delayed diagnoses, and an acceptable rate of non-therapeutic laparotomies.

Abstract
Blunt intestinal mesenteric trauma (BIMT) is a rare injury with a high morbidity and mortality. It is a diagnostic dilemma for Trauma Surgeons and Emergency Physicians. This study was undertaken to assess the role of computed tomography (CT) in BIMT. Data were analyzed from 1995 to 2002. Thirty-six cases of BIMT were identified: 16 isolated and 20 non-isolated injuries. Initial CT scan was abnormal in 74% (17 out of 23), and 83% on retrospect (2 additional cases). CT scans were abnormal (initial and repeat) in 96% (22 out of 23). The most common abnormalities were free fluid (78%), mesenteric stranding or edema (39%), bowel wall hematoma, or edema (30%). Free air was seen in 31% and oral contrast extravasation in 15% of cases of bowel perforation. CT scan findings in BIMT can be subtle and non-specific. Suspicion of BIMT warrants close observation and probably further diagnostic testing.

Abstract
BACKGROUND Computed tomographic (CT) scanning using intravenous and oral contrast material has traditionally been advocated for the evaluation of intra-abdominal injury, including blunt bowel and mesenteric injuries (BBMIs). The necessity of oral contrast in detecting these injuries has recently been called into question. The purpose of this study was to determine the sensitivity and specificity of CT scanning without oral contrast for BBMIs. METHODS We prospectively enrolled 500 consecutive blunt trauma patients who received CT imaging and interpretation (CT-Read1) of the abdomen from July 2000 to November 2001. All patients were imaged without oral contrast, but with intravenous contrast. CT images were reviewed within 24 hours of admission by a research radiologist (CT-Read2) blinded to CT-Read1. For study purposes, true BBMI was determined to be present if either laparotomy or autopsy identified bowel or mesenteric injury, or both CT-Read2 and the hospital discharge summary described bowel or mesenteric injury. Three-month telephone follow-up was also completed. RESULTS CT-Read1 detected 19 of 20 bowel and mesenteric injuries. CT-Read1 missed one duodenal perforation. There were two patients with false-positive interpretations of CT-Read1 for bowel injury. The sensitivity and specificity of CT imaging for the detection of BBMIs were 95.0% and 99.6%, respectively. CONCLUSION CT imaging of the abdomen without oral contrast for detection of BBMIs compares favorably with CT imaging using oral contrast.

Abstract
OBJECTIVES Blunt SBI is infrequent and its diagnosis may be difficult, especially in the face of confounding variables. The purpose of this study was to evaluate methods for making the diagnosis of blunt SBI. METHODS Patients with blunt small bowel injury (SBI) were identified from the registries of 95 trauma centers for a 2-year period (1998-1999). Patients with SBI (cases) were matched by age and Injury Severity Score with a blunt trauma patient receiving an abdominal workup who did not have SBI (controls). RESULTS Logistic regression models were unable to differentiate SBI with perforation from SBI without perforation. Thirteen percent of patients with documented perforating SBI had normal abdominal computed tomographic scans preoperatively. CONCLUSION Alone or in combination, current diagnostic approaches lack sensitivity in the diagnosis of perforated SBI. Improvements in diagnostic methods and approaches are needed to ensure the prompt diagnosis of this uncommon but potentially devastating injury.

Abstract
PURPOSE To report a rare complication of antegrade femoral access for percutaneous aspiration thromboembolectomy and transluminal angioplasty. CASE REPORT A 73-year-old obese woman underwent antegrade femoral aspiration thromboembolectomy for lower limb arterial embolism. Fifteen hours later, she presented with acute abdomen and decreased hemoglobin. Computed tomography showed small bowel obstruction, incarcerated femoral hernia, and free peritoneal air and fluid suggesting bowel perforation. Emergent laparotomy revealed an incarcerated, perforated femoral bowel loop and 4-quadrant peritonitis. CONCLUSIONS Femoral hernia injury is an exceptional complication of vascular interventions. Knowledge of this potential hazard may help to avoid its occurrence.

Abstract
BACKGROUND Abdominal computed tomographic (CT) scan is accepted as the primary diagnostic modality in stable patients with blunt abdominal trauma. A recent survey of 328 trauma surgeons demonstrated marked variation in the management of patients with head injuries and the finding of free intra-abdominal fluid without solid organ injury on CT scan. This study was undertaken to attempt to determine what to do when free fluid without solid organ injury is seen on abdominal CT scan in patients with blunt trauma. METHODS Articles concerning the incidence and significance of free intra-abdominal fluid on CT scan of blunt trauma patients without solid organ injury were systematically reviewed. A MEDLINE search was performed using terms such as tomography-x-ray computed, wounds-nonpenetrating, small intestine/injuries, time factors, and abdominal trauma and diagnostic tests. Bibliographies of pertinent articles were reviewed. Appropriate articles were evaluated for quality and data were combined to reach a conclusion. RESULTS Meta-analysis could not be performed because no randomized, prospective, controlled trials could be found. Forty-one articles were excluded from the analysis because they looked at only patients with known injuries to intestine, diaphragm, or pancreas and the investigation of the CT scan findings did not include negative scans. Ten articles, which described CT scan results for all patients presenting with blunt abdominal trauma for a defined period of time, formed the basis of this study. Isolated free fluid was seen in 463 (2.8%) of over 16,000 blunt trauma patients scanned. A therapeutic laparotomy was performed in only 122 (27%) of these patients. CONCLUSION The isolated finding of free intra-abdominal fluid on CT scan in patients with blunt trauma and no solid organ injury does not warrant laparotomy. Alert patients may be followed with physical examination. Patients with altered mental status should undergo diagnostic peritoneal lavage.

Abstract
BACKGROUND Review of hemodynamically stable patients who undergo laparotomy for trauma greater than 4 hours after admission is an American College of Surgeons quality improvement filter. We reviewed our recent experience with patients who underwent laparotomy for trauma greater than 4 hours after admission to evaluate the reasons for delay, and to determine whether they were because of failure of nonoperative management or other causes. METHODS The registry at our Level I trauma center was searched from January 1998 through December 2000 for patients who required a laparotomy for trauma greater than 4 hours after admission. Of 3,369 admitted blunt trauma patients, 90 (2.7%) underwent laparotomy for trauma, of which 26 (29%) were identified as delayed laparotomies greater than 4 hours after admission. RESULTS The most common mechanism of injury was motor vehicle crash, the mean Injury Severity Score was 18, and 65% of the patients had significant distracting injuries. Five patients had laparotomy greater than 24 hours after admission. The average time to the operating room in the remaining patients was 8.6 hours. Clinical examination (61%) findings were the most common indication for operation. Gastrointestinal (GI) tract injury was the most common injury associated with delay in laparotomy (58%). CONCLUSION GI tract injuries are the predominant injury leading to delayed laparotomy for blunt trauma (58%). Failed nonoperative management of solid organ injuries occurred less frequently (15%). Future efforts should concentrate on earlier identification of GI tract injury. Delayed laparotomy for blunt abdominal trauma is a valid quality improvement measure.

Abstract
BACKGROUND Mandatory celiotomy has been proposed for all patients with unexplained free fluid on abdominal computed tomography (CT) scanning after blunt abdominal injury. This recommendation has been based upon retrospective data and concerns over the potential morbidity from the late diagnosis of blunt intestinal injury. This study examined the rate of intestinal injury in patients with free fluid on abdominal CT after blunt abdominal trauma. METHODS This study was a multicenter prospective series of all patients with blunt abdominal trauma admitted to four level I trauma centers over 22 months. Data were collected concurrently at the time of patient enrollment and included demographics, injury severity score, findings on CT scan, and presence or absence of blunt intestinal injury. This database was specifically queried for those patients who had free fluid without solid organ injury. RESULTS In all, 2,299 patients were evaluated. Free fluid was present in 265. Of these, 90 patients had isolated free fluid with only 7 having a blunt intestinal injury. Conversely, 91% of patients with free fluid did not. All patients with free fluid were observed for a mean of 8 days (95% confidence interval 6.1 to 10.4, range 1 to 131). There were no missed injuries. CONCLUSIONS Free fluid on abdominal CT scan does not mandate celiotomy. Serial observation with the possible use of other adjunctive tests is recommended.

Abstract
Recent advances in blunt thoraco-abdominal trauma management include improvements in imaging, particularly in trauma bay ultrasound. Indications for non-operative management have expanded for solid organ and aortic injury. The physiology of abdominal compartment syndrome continues to be defined, with resulting improvements in care.
