Abstract
Pregnancy is a time of tremendous physiologic change and vulnerability. At any point, symptoms and complications can prompt the need for emergency care, and these can range from minor to life-threatening. Emergency physicians must be prepared to treat any of these complications, in addition to rescucitating the critically ill and injured pregnant patient. To optimally care for these patients, it is paramount to be aware of the unique physiologic changes that occur during pregnancy. The focus of this review is to discuss illnesses unique to pregnancy and additional aspects of resuscitation that must be considered when caring for a critically ill pregnant patient.

Abstract
BACKGROUND Focused Assessment with Sonography for Trauma (FAST) has supplanted diagnostic peritoneal lavage (DPL) as the preferred bedside evaluation for traumatic hemoperitoneum. Diagnostic peritoneal aspiration (DPA) is a simpler, faster modification of DPL with an unclear role in contemporary practice. This study delineated modern roles for DPA and defined its diagnostic yield. METHODS All trauma patients presenting to our Level I center who underwent DPA were included (May 2015 to May 2020). Demographics, comorbidities, clinical/injury data, and outcomes were collected. The diagnostic yield and accuracy of DPA were calculated against the criterion standard of hemoperitoneum at exploratory laparotomy or computed tomography scan. RESULTS In total, 41 patients underwent DPA, typically after blunt trauma (n = 37, 90%). Patients were almost exclusively hypotensive (n = 20, 49%) or in arrest (n = 18, 44%). Most patients had an equivocal or negative FAST and hypotension or return of spontaneous circulation after resuscitative thoracotomy (n = 32, 78%); or had a positive FAST and known cirrhosis (n = 4, 10%). In two (5%) patients, one obese, the catheter failed to access the peritoneal cavity. Diagnostic peritoneal aspiration sensitivity, specificity, positive predictive value, and negative predictive value were 80%, 100%, 100%, and 90%, with an accuracy of 93%. One (2%) complication, a small bowel injury, occurred. CONCLUSION Despite near ubiquitous FAST availability, DPA remains important in diagnosing or excluding hemoperitoneum with exceedingly low rates of failure and complications. Diagnostic peritoneal aspiration is most conclusive when positive, without false positives in this study. Diagnostic peritoneal aspiration was most used among blunt hypotensive or postarrest patients who had an equivocal or negative FAST, in whom the preliminary diagnosis of hemoperitoneum is a critically important decision making branch point. LEVEL OF EVIDENCE Diagnostic, level III.

Cancer Med 2020; 9:8940-8949. [PMID: 33047873 PMCID: PMC7724308 DOI: 10.1002/cam4.3518] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2020] [Revised: 09/17/2020] [Accepted: 09/18/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Positive peritoneal cytology (PCY) indicates metastasis (M1) in gastric cancer (GC) patients; both the American and Chinese guidelines recommend laparoscopic peritoneal lavage (LPL) for cytology. However, relatively high costs impair the widespread use of LPL in some resource-limited regions in China, and the cost-effectiveness of PCY testing remains unclear. Therefore, we performed a decision analysis to evaluate the cost-effectiveness of PCY testing by comparing the guideline-recommended intraoperative LPL, a newly proposed preoperative percutaneous peritoneal lavage (PPL), and a third strategy of exploratory laparotomy with no cytology testing (ELNC) among GC patients. METHODS We developed a decision-analytic Markov model of the aforementioned three strategies for a hypothetical cohort of GC patients with curative intent after initial imaging, from the perspective of Chinese society. We estimated costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs) as primary outcomes; we also conducted one-way and probabilistic sensitivity analyses to investigate the model's robustness. RESULTS We found that ELNC was dominated (i.e., more expensive and less effective) by PPL and LPL. LPL was the most cost-effective method with an ICER of US$17,200/QALY compared to PPL, which was below the Chinese willingness-to-pay (WTP) threshold of US$29,313 per QALY gained. In sensitivity analyses, PPL was more likely to be cost-effective with a lower WTP threshold. CONCLUSIONS Cytology testing through either LPL or PPL was less expensive and more effective than ELNC among GC patients. Moreover, LPL was the most cost-effective modality at the current WTP threshold, while PPL could potentially be cost-effective in lower-income areas.

Abstract
Background and aims Penetrating abdominal trauma can be caused by a variety of weapons which require different management protocols. After a long era of mandatory laparotomy for abdominal gunshot wounds, the concept of selective laparotomy and conservative management in the form of serial observations has been introduced in some centers. This study aims to assess the feasibility and safety of conservative management and close observation of victims of low energy transfer shotgun penetrating abdominal injury. Methods A prospective cohort study of hemodynamically stable patients who had sustained low energy transfer shotgun injuries to the abdomen who presented to the surgical emergency department of Cairo University Hospitals from May 2016 to January 2019. They were subjected to a conservative management and follow-up protocol. Results A total of 250 patients (167 males and 83 females) were included. The conservative management protocol was successful in 217/250 patients (86.8%), unsuccessful in 22 patients (8.8%) where abdominal exploration was done either open or laparoscopically. Delayed diagnosis of bowel injury occurred in one patient (0.4%). There was one death (0.4%) and abdominal exploration was negative in 10 (4%) patients. Conclusion We recommend this conservative protocol for the victims of low energy transfer penetrating shotgun injuries which may save many patients from the morbidities of unnecessary laparotomy. We accept that the injury pattern may not be sufficiently common in many countries to allow comfort with this non-operative approach.

Abstract
INTRODUCTION It could be claimed that extended focused assessment with sonography for trauma (e-FAST) is the most important use of ultrasound in every emergency department (ED). It is a rapid, repeatable, non-invasive bedside method that was designed to answer one single question, which is, "whether free fluid is present in the peritoneal, pleural and pericardial cavity or not?" This examination may also be used to evaluate the lungs for pneumothorax. OBJECTIVE The current comparative study was conducted to assess the accuracy and reproducibility of e-FAST performed by emergency medicine residents (EMRs) and radiology consultants (RCs) in multiple trauma patients. METHOD This diagnostic accuracy study was conducted prospectively in patients presenting over a period of 12 months from January 1, 2013, to December 31, 2013 to the ED of Kerala Institute of Medical Sciences (KIMS), Kerala, India. All multiple trauma patients older than 18 years of age presenting within 24 hours of their traumatic event, who underwent both e-FAST and thoracoabdominal computed tomography (CT) scan were included. The e-FAST exams were first performed by the EMRs and then by RCs. The thoracoabdominal CT scan findings were considered as the gold standard. The results were compared between both groups to assess the inter-observer variability. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated both for EMRs and RCs. RESULTS In the study period, 150 patients with a mean age of 42.06 ± 18.1 years were evaluated (76.7% male). Only 19 cases (12.7%) had a history of fall from a height, and the others were admitted due to RTA. Thirty-four cases (22.7%) did not require surgery; but the others underwent various interventions. Both EMRs and RCs reported positive findings in 20 cases (13.3%) and negative findings in 130 cases (86.7%). The correlation of e-FAST done by EMRs with that by RCs was 100%. E-FAST exam had a sensitivity of 90.4%, specificity 99.2%, PPV 95.0%, NPV 98.4%, and accuracy 98%, both for EMRs and RCs. CONCLUSION Based on the findings, the sensitivity, specificity, and accuracy of e-FAST exams performed by EMRs were equal to those performed by RCs. It seems that e-FAST performed by EMRs were almost accurate during the initial trauma resuscitation in the ED of a level one trauma center in India.

Abstract
Severe pelvic trauma is a challenging condition. The pelvis can create multifocal hemorrhage that is not easily compressible nor managed by traditional surgical methods such as tying off a blood vessel or removing an organ. Its treatment often requires reapproximation of bony structures, damage control resuscitation, assessment for associated injuries, and triage of investigations, as well as multimodality hemorrhage control (external fixation, preperitoneal packing, angioembolization, REBOA [resuscitative endovascular balloon occlusion of the aorta]) by multidisciplinary trauma specialists (general surgeons, orthopedic surgeons, endovascular surgeons/interventional radiologists). This article explores this complex clinical problem and provides a practical approach to its management.

Abstract
BACKGROUND The conservative treatment of liver trauma has made important progress over the last 10 years at the Trauma University Hospital in Tirana, Albania. The percentage of success was 58.7%. The aims of this study were to analyze the conservative treatment of liver trauma and to compare the results with those in the literature. METHODS This study was conducted prospectively from January 2009 to December 2012. We analyzed 173 patients admitted to our hospital with liver trauma. Liver injuries were evaluated according to the American Association for the Surgery of Trauma and the World Society of Emergency Surgery classification, while the anatomic gravity of the associated injuries was defined using the Injury Severity Score system. The potential mortality was estimated with the Revised Trauma Score. RESULTS Out of the 173 patients with liver trauma, 83.2% were male. The main cause of liver trauma was motor vehicle crashes (50.9%). Blunt trauma was the cause of liver injury in 129 cases (74.6%), and penetrating trauma occurred in 44 cases (25.4%). Initially, the decision was to manage 88 cases (50.9%) via the conservative approach. Of these, 73 cases (42.2%) were successfully treated with conservative treatment, while in 15 cases (17.2%), this approach failed. The success rate of conservative treatment by grade of injuries was as follows: grade I (38.4%), grade II (30.1%), grade III (28.8%), and grade IV (2.7%). The likelihood of the success of conservative treatment had a significant correlation with the grade of the liver injury (p < 0.00001), associated intra-abdominal injuries (p = 0.00051), and complications (z = 2.3169, p = 0.02051). The overall mortality rate of liver trauma was 13.2%. CONCLUSIONS The likelihood of success in using conservative treatment had a significant correlation with the grade of liver injury and associated intra-abdominal injuries. The limited hospital resources and low level of consensus on conservative treatment had a negative impact on the level of success.

Abstract
BACKGROUND Positive peritoneal cytology is classified as M1 disease in gastric and pancreatic cancer. While peritoneal cytology is typically obtained by laparoscopic peritoneal lavage, this study sought to examine the feasibility and safety of performing this percutaneously, with monitored anesthesia care and in combination with other diagnostic procedures to condense and expedite the staging process. METHODS Patients with gastric or pancreatic cancer scheduled for laparoscopy with peritoneal lavage were prospectively enrolled to undergo intraoperative percutaneous peritoneal lavage prior to laparoscopic peritoneal lavage. Saline was infused through a percutaneously-inserted catheter and fluid was collected for peritoneal cytology. Three-quadrant washings collected during laparoscopy were also sent for peritoneal cytology. The primary outcome was to evaluate the sensitivity and specificity of percutaneous peritoneal lavage for detecting positive peritoneal cytology compared with the gold standard of laparoscopic peritoneal lavage, while the secondary outcome was to determine safety. RESULTS Percutaneous peritoneal lavage was successfully performed in 70 of 76 patients (92%). Ten of 48 gastric cancer patients (21%) and three of 22 pancreatic cancer patients (14%) had positive percutaneous and laparoscopic peritoneal cytology. Two additional gastric cancer patients had positive laparoscopic peritoneal cytology only. Sensitivity and specificity of percutaneous peritoneal lavage compared with laparoscopic peritoneal lavage were 87% and 100%, respectively. No complications occurred with percutaneous peritoneal lavage. CONCLUSIONS Percutaneous peritoneal lavage is a safe and effective minimally invasive alternative to laparoscopic peritoneal lavage for the diagnosis of metastatic gastric and pancreatic cancer. It is possible this can be utilized in an outpatient setting, such as during endoscopy, to allow for earlier diagnosis of M1 disease and decreased time to appropriate treatment.

Abstract
Isolated mesenteric vascular injury following blunt abdominal trauma as a result of road traffic accidents is rare. Delay in reaching hospital, delay in diagnosis, or late operative intervention could lead to increased morbidity, prolonged hospital stay and even mortality. We herein report a case of such injury with subsequent massive segmental small bowel infarction. The patient was referred to our institute ten hours after the alleged accident. Resection of the infarcted bowel segment with end-to-end anastomosis was done. We highlight the various techniques for timely diagnosis and management of isolated mesenteric injuries. A high index of suspicion, early detection and prompt surgical intervention is required when there are minimal symptoms and signs, which might avert adverse outcome.

Abstract
Abdominal compartment syndrome (ACS) is a known complication of the large-volume resuscitation that burn patients receive. Bowel ischemia has been theorized to occur in ACS but has yet to be described in the literature. The authors report an occurrence of late bowel obstruction related to ACS-associated bowel ischemia in a burn patient. A four-year-old previously well girl sustained 70% total body surface area burns with inhalation injury. The areas injured were the anterior neck, circumferential torso from neck to waist, left arm, left thigh and two-thirds of her right thigh. Fluid resuscitation was initially administered using the modified Parkland formula. Her transfer to the regional burn unit from a local hospital was complicated by early septic shock from a line infection, which increased her resuscitation fluid requirements. Infection ultimately led to multiple instances of ACS. Intervention with percutaneous drainage led to immediate improvement; however, the episodes of ACS resulted in a late small bowel obstruction secondary to stricture, requiring a laparotomy and bowel resection.

Abstract
BACKGROUND Focused assessment with sonography in trauma (FAST) is a method for prompt detection of the abdominal free fluid in patients with abdominal trauma. OBJECTIVES This study was conducted to compare the diagnostic accuracy of FAST performed by emergency medicine residents (EMR) and radiology residents (RRs) in detecting peritoneal free fluids. PATIENTS AND METHODS Patients triaged in the emergency department with blunt abdominal trauma, high energy trauma, and multiple traumas underwent a FAST examination by EMRs and RRs with the same techniques to obtain the standard views. Ultrasound findings for free fluid in peritoneal cavity for each patient (positive/negative) were compared with the results of computed tomography, operative exploration, or observation as the final outcome. RESULTS A total of 138 patients were included in the final analysis. Good diagnostic agreement was noted between the results of FAST scans performed by EMRs and RRs (κ = 0.701, P < 0.001), also between the results of EMRs-performed FAST and the final outcome (κ = 0.830, P < 0.0010), and finally between the results of RRs-performed FAST and final outcome (κ = 0.795, P < 0.001). No significant differences were noted between EMRs- and RRs-performed FASTs regarding sensitivity (84.6% vs 84.6%), specificity (98.4% vs 97.6%), positive predictive value (84.6% vs 84.6%), and negative predictive value (98.4% vs 98.4%). CONCLUSIONS Trained EMRs like their fellow RRs have the ability to perform FAST scan with high diagnostic value in patients with blunt abdominal trauma.

Abstract
AIM: To assess the safety and feasibility of diagnostic peritoneal lavage (DPL) in gastric cancer patients and determine whether DPL can be used to assess peritoneal cytology in patients with gastric cancer.
METHODS: Patients with gastric adenocarcinoma were prospectively enrolled to undergo DPL prior to diagnostic laparoscopy (DL). Saline was instilled through a percutaneous catheter and fluid was collected for cytology (DPL-cyt). Washings obtained during DL were used as controls (DL-cyt).
RESULTS: DPL was successful in 22 of 27 patients (81.5%). Among the 22 cases of successful DPL, 12 had positive cytology (54.5%). Positive DPL-cyt specimens were consistent with DL-cyt specimens in 12/12 cases (specificity = 100%).
CONCLUSION: DPL is a safe method for detecting positive cytology in patients with gastric cancer.

Abstract
We reviewed recent data on the prevalence, risk factors, complications, and management of trauma during pregnancy. Using the terms "trauma" and "pregnancy" along with specified mechanisms of injury, we queried the PubMed database for studies reported from Jan. 1, 1990, through May 1, 2012. Studies with the largest number of patients for a given injury type and that were population-based and/or prospective were included. Case reports and case series were used only when more robust studies were lacking. A total of 1164 abstracts were reviewed and 225 met criteria for inclusion. Domestic violence/intimate partner violence and motor vehicle crashes are the predominant causes of reported trauma during pregnancy. Management of trauma during pregnancy is dictated by its severity and should be initially geared toward maternal stabilization. Minor trauma can often be safely evaluated with simple diagnostic modalities. Pregnancy should not lead to underdiagnosis or undertreatment of trauma due to unfounded fears of fetal effects. More studies are required to elucidate the safest and most cost-effective strategies for the management of trauma in pregnancy.

Abstract
BACKGROUND AND OBJECTIVES Positive peritoneal cytology equates M1 disease in patients with gastric cancer. Diagnostic peritoneal lavage (DPL) is a proven test to detect occult visceral injury in trauma patients. The objective of this study is to determine whether DPL can be used to assess peritoneal cytology in patients with gastric cancer. METHODS Patients with gastric adenocarcinoma were prospectively enrolled to undergo DPL prior to diagnostic laparoscopy (DL). Saline was instilled through a percutaneous catheter and fluid was collected for cytology (DPL-cyt). Washings obtained during DL were used as controls (DL-cyt). RESULTS DPL was successful in 22/27 patients (81.5%). Among the 22 successful DPLs, 12 had positive cytology (54.5%). Positive DPL-cyt specimens matched DL-cyt specimens in 12/12 cases (specificity = 100%). One of 10 cases with negative DPL-cyt was positive on the final DL-cyt (sensitivity = 92%). There were six patients with negative DPL-cyt who had visible M1 disease diagnosed with DL (DPL evaluation of M1 disease, sensitivity 54.5%, specificity = 100%). CONCLUSIONS DPL is a safe method of detecting positive cytology in patients with gastric cancer, however gross M1 disease may be missed without visual inspection. The specific role of DPL in the staging workup of patients with gastric cancer remains to be determined.

Abstract
Background: Focused assessment with sonography for trauma (FAST) is an important skill during trauma resuscitation. Use of point of care ultrasound among the trauma team working in emergency care settings is lacking in India. Objective: To determine the accuracy of FAST done by nonradiologists (NR) when compared to radiologists during primary survey of trauma victims in the emergency department of a level 1 trauma center in India. Materials and Methods: A prospective study was done during primary survey of resuscitation of nonconsecutive patients in the resuscitation bay. The study subjects included NR such as one consultant emergency medicine, two medicine residents, one orthopedic resident and one surgery resident working as trauma team. These subjects underwent training at 3-day workshop on emergency sonography and performed 20 supervised positive and negative scans for free fluid. The FAST scans were first performed by NR and then by radiology residents (RR). The performers were blinded to each other's sonography findings. Computed tomography (CT) and laparotomy findings were used as gold standard whichever was feasible. Results were compared between both the groups. Intraobserver variability among NR and RR were noted. Results: Out of 150 scans 144 scans were analyzed. Mean age of the patients was 28 [1-70] years. Out of 24 true positive patients 18 underwent CT scan and exploratory laparotomies were done in six patients. Sensitivity of FAST done by NR and RR were 100% and 95.6% and specificity was 97.5% in both groups. Positive predictive value among NR and RR were 88.8%, 88.46% and negative predictive value were 97.5% and 99.15%. Intraobserver performance variation ranged from 87 to 97%. Conclusion: FAST performed by NRs is accurate during initial trauma resuscitation in the emergency department of a level 1 trauma center in India.

Abstract
Penetrating traumas are rare in France and mainly due to stabbing. Knives are less lethal than firearms. The initial clinical assessment is the cornerstone of hospital care. It remains a priority and can quickly lead to a surgical treatment first. Urgent surgical indications are hemorrhagic shock, evisceration and peritonitis. Dying patients should be immediately taken to the operating room for rescue laparotomy or thoracotomy. Ultrasonography and chest radiography are performed before damage control surgery for hemodynamic unstable critical patients. Stable patients are scanned by CT and in some cases may benefit from non-operative strategy. Mortality remains high, initially due to bleeding complications and secondarily to infectious complications. Early and appropriate surgery can reduce morbidity and mortality. Non-operative strategy is only possible in selected patients in trained trauma centers and with intensive supervision by experienced staff.

Abstract
OBJECTIVES To determine the cause, presentation, anatomical distribution, diagnostic method, management and outcome of intestinal injuries from blunt abdominal trauma. METHODS The study included 47 patients who underwent laparotomy for intestinal injuries from blunt abdominal trauma over a period of 4 years. A retrospective study was conducted and the patients were analyzed with respect to the cause, presentation, anatomical distribution, diagnostic methods, associated injuries, treatment and mortality. RESULTS 47 patients with 62 major injuries to the bowel and mesentery due to blunt abdominal trauma were reviewed. The male to female ratio was 8.4: 1 and the average age was 34.98 years. There were 44 injuries to the small intestine including 1 duodenal injury, 11 colonic injuries and 7 injuries to the mesentry. 26 patients were injured in road traffic accidents. Out of 29 patients with intestinal perforation, free peritoneal air was present on plain abdominal and chest radiography in 23 patients. 18 patients underwent laparotomy on the basis of clinical findings alone. The commonest injury was a perforation at the antimesentric border of the small bowel. Treatment consisted of simple closure of the perforation, resection and anastomosis and repair followed by protective colostomy for colonic perforations. 3 (6.38%) deaths were recorded, while 8 (17.02%) patients developed major complications. CONCLUSION Although early recognition of intestinal injuries from blunt abdominal trauma is difficult, it is very important due to its tremendous infectious potential. Intestinal perforations are often associated with severe injuries which are probably be the determining factors in survival.

Abstract
BACKGROUND Advances in diagnostic imaging and the introduction of damage control strategy in trauma have influenced our approach to treating liver trauma patients. The objective of the present study was to investigate the impact of change in liver trauma management on outcome. METHODS A total of 468 consecutive patients with liver trauma treated between 1986 and 2010 at a single level 1 trauma center were reviewed. Mechanisms of injury, diagnostic imaging, hepatic and associated injuries, management (operative [OM] vs. nonoperative [NOM]), and outcome were evaluated. The main outcome analysis compared mortality for the early study period (1986-1996) versus the later study period (1997-2010). RESULTS 395 patients (84%) presented with blunt liver trauma and 73 (16%) with penetrating liver trauma. Of these, 233 patients were treated with OM (50%) versus 235 with NOM (50%). The mortality rate was 33% for the early period and 20% for the later period (odds ratio 0.19; 95% CI 0.07-0.50, P = 0.001). A significantly increased use of computed tomography (CT) as the initial diagnostic modality was observed in the late period, which almost completely replaced peritoneal lavage and ultrasound. There was a significant shift to NOM in the later period (early 15%, late 63%) with a low conversion rate to OM of 4.2%. Age, degree of hepatic and head injury, injury severity, intubation at admission, and early period were independent predictors of mortality in the multivariate analysis. CONCLUSIONS Integration of CT in early trauma-room management and shift to NOM in hemodynamically stable patients resulted in improved survival and should be the gold standard management for liver trauma.

Abstract
OBJECTIVES During the last 2 decades, the advent of new technologies in trauma patient care may have resulted in a decreased number of diagnostic peritoneal lavage (DPL) evaluations. In this study, it is hypothesized that fewer DPL are being performed at a midwestern trauma center. Such negative trends may make the inclusion of DPL in current trauma education potentially outdated and no longer universally appropriate in trauma evaluation algorithms. DESIGN, SETTING, AND PARTICIPANTS This retrospective observational study of a level I trauma center includes patients from January 1998 through September 2010. The total number of trauma-related DPL procedures performed annually during the study period was determined along with accompanying facility and trauma patient level data. RESULTS A total of 24 DPLs were performed at the target trauma center during the study period. There was a significant decrease (p = 0.0018) in the use of DPL despite a significant increase (p < 0.0001) in the proportion of trauma patients with an injury severity score > 15. CONCLUSIONS Study data demonstrated a decrease in the use of DPL as a diagnostic modality in the evaluation of blunt abdominal trauma patients at a medium-sized midwestern center. These data provide historic facility-level evidence of a practice change. Such information may support a recommendation that the American College of Surgeons revisit its current curriculum for Advanced Trauma Life Support (ATLS). Specifically, we propose the American College of Surgeons consider changing DPL instruction to an optional component of ATLS.

Abstract
The liver is one of the most commonly injured organs in abdominal trauma. Recent advancements in imaging studies and enhanced critical care monitoring strategies have shifted the paradigm for the management of liver injuries. Nonoperative management of both low- and high-grade injuries can be successful in hemodynamically stable patients. Direct suture ligation of bleeding parenchymal vessels, total vascular isolation with repair of venous injuries, and the advent of damage control surgery have all improved outcomes in the hemodynamically unstable patient population. Anatomical resection of the liver and use of atriocaval shunt are rarely indicated.

Abstract
BACKGROUND Blunt and penetrating liver trauma is common and often presents major diagnostic and management problems. METHODS A literature review was undertaken to determine the current consensus on investigation and management strategies. RESULTS The liver is the most frequently injured organ following abdominal trauma. Immediate assessment with ultrasound has replaced diagnostic peritoneal lavage in the resuscitation room, but computerised tomography remains the gold standard investigation. Nonoperative management is preferred in stable patients but laparotomy is indicated in unstable patients. Damage control techniques such as perihepatic packing, hepatotomy plus direct suture, and resectional debridement are recommended. Major complex surgical procedures such as anatomical resection or atriocaval shunting are now thought to be redundant in the emergency setting. Packing is also recommended for the inexperienced surgeon to allow control and stabilisation prior to transfer to a tertiary centre. Interventional radiological techniques are becoming more widely used, particularly in patients who are being managed nonoperatively or have been stabilised by perihepatic packing. CONCLUSIONS Management of liver injuries has evolved significantly throughout the last two decades. In the absence of other abdominal injuries, operative management can usually be avoided. Patients with more complex injuries or subsequent complications should be transferred to a specialist centre to optimise final outcome.

Abstract
The nonoperative care of intraabdominal trauma in the polytraumatised patient greatly depends on imaging techniques. The haemodynamically unstable patient should undergo expedient sonography to rule out abdominal haemorrhage. The use of computer tomography (CT) in this difficult patient group is also currently evaluated, however it takes specific amendments to the protocol and institution. In the hemodynamically stable patient however, computer tomography is the modality of choice to evaluate the injured abdomen. Nonoperative treatment can be successful in up to 80% of selected cases. Adjuncts to nonoperative care include embolisation of the spleen and liver in cases of arterial bleeding, and endoscopic retrograde cholangio pancreaticography (ERCP) and stenting for injuries to the biliary tree.

Abstract
BACKGROUND For hemodynamically stable patients with suspected abdominal injuries, the diagnostic accuracy of computed tomographic scans remains unmatched. Focused assessment with sonography for trauma (FAST) is useful in trauma evaluation to identify intraabdominal fluid early in the unstable patient. In skilled hands, sensitivity is shown to be close to 100%. However, some recent studies have questioned its sensitivity in subgroups at risk of bleeding. In most studies, hemodynamic markers of instability have been limited to hypotension. The purpose of this study was to determine the sensitivity and specificity of initial FAST for detection of hemoperitoneum in the potentially unstable patient as judged by objective hemodynamic parameters available early during resuscitation. METHODS Prospective observational study at a major European trauma center. FAST was performed in trauma patients by the trauma team radiologist. The study population consisted of the subgroup deemed potentially unstable on arrival as defined by systolic blood pressure < or =90 mm Hg, pulse rate > or =120, or base deficit > or =8. Results were compared with one of the following reference standards: computed tomographic scan, diagnostic peritoneal lavage, exploratory laparotomy, or observation. RESULTS One hundred and four patients constituted the study group. There were 75 true-negative, 10 false-negative, 16 true-positive, and 3 false-positive FAST results. Sensitivity and specificity were 62% and 96%, positive and negative predictive values 84% and 89%, respectively, and overall accuracy was 88%. CONCLUSION A negative initial FAST in hemodynamically unstable patients, even in the hands of radiologists, cannot reliably exclude intraabdominal bleeding. These patients should undergo additional diagnostic tests to exclude intraperitoneal hemorrhage.

Abstract
Diagnostic peritoneal lavage (DPL) is a highly accurate test for evaluating intraperitoneal hemorrhage or a ruptured hollow viscus, but is performed less frequently today due to the increased use of focused abdominal sonography for trauma (FAST) and helical computed tomography (CT). All three of these exams have advantages and disadvantages and thus each still play unique roles in the evaluation of abdominal trauma. Since DPL is performed less frequently today, a review of its indications, technique, and interpretation is pertinent.

Abstract
Ultrasound examinations in trauma patients should be done in the emergency department using curved-array (3.5-7.5 MHz) probes. Blunt trauma of the abdomen and thorax must be regarded as a single organ injury. Sonography is the imaging technique of first choice and has completely replaced peritoneal lavage. Paramount advantages are its ability to provide rapid information and reproducible results at short intervals and in a noninvasive manner. The sensitivity and specificity of sonography in detecting intraabdominal fluid are 97-100% and 80-90%, respectively. To achieve such good results, though, adequate education in ultrasound and state-of-the-art devices is crucial. Clinical experiences prove that standardized sonography must be part of polytrauma management and should be integrated in advanced trauma life support courses. Technical improvements with better image quality and miniaturization of hardware will contribute to increase the use of this technique. However, ultrasound does not replace computed tomography for follow-up in answering more sophisticated questions in multiple injured patients.

Abstract
BACKGROUND Historically, military surgical doctrine has mandated exploratory laparotomy for all penetrating fragmentation wounds. We hypothesized that stable patients with abdominal fragmentation injuries whose computerized tomography (CT) scans for intraperitoneal or retroperitoneal penetration disclosed nothing abnormal, can be safely observed without therapeutic laparotomy. METHODS We retrospectively studied all hemodynamically stable patients with penetrating fragmentation wounds to the back, flank, lower chest, abdomen, and pelvis evaluated by abdominal physical examination (PE), CT, or ultrasound treated during a 6-month period at one combat support hospital. Sensitivity, specificity, and positive and negative predictive values were calculated comparing each positive test to laparotomy and each negative test to successful nonoperative management. RESULTS One hundred forty-five patients met study criteria. Based on CT scans, 85 (59%) patients were managed nonoperatively; 60 (41%) underwent laparotomy. Forty-five of 60 (75%) of laparotomies were therapeutic. CT scan for intraperitoneal or retroperitoneal penetration that disclosed nothing abnormal was 99% predictive of successful nonoperative management. In detecting intra-abdominal injury requiring laparotomy, sensitivity for each method was 30.2% (PE), 11.7% (ultrasound), and 97.8% (CT) (p < 0.05). Specificity was 94.8% (PE), 100% (ultrasound), and 84.8% (CT). The areas under the receiver operating characteristic (ROC) curves were 0.565 (PE), 0.543 (ultrasound), and 0.929 (CT) (p < 0.0001). All patients with a positive ultrasound (n = 4) underwent therapeutic laparotomy. CONCLUSION PE alone was unreliable in stable patients with abdominal fragmentation injuries. The clinical value of ultrasound results was limited, likely because the majority of these stable patients did not have injuries associated with the large accumulation of peritoneal fluid. CT scan safely and effectively analyzed nonoperative management of penetrating abdominal fragmentation injuries and should be the diagnostic study of choice in all stable patients without peritonitis with abdominal, flank, back, or pelvic combat fragmentation wounds.

Abstract
Clinical practice guidelines have been shown to improve the delivery of care. Anterior abdominal stab wounds, although uncommon, pose a challenge in both rural and urban trauma care. A multidisciplinary working party was established to assist in the development of evidence-based guidelines to answer three key clinical questions: (i) What is the ideal prehospital management of anterior abdominal stab wounds? (ii) What is the ideal management of anterior abdominal stab wounds in a rural or urban hospital without an on-call surgeon? (iii) What is the ideal emergency management of stable patients with anterior abdominal stab wounds when surgical service is available? A systematic review, using Cochrane method, was undertaken. The data were graded by level of evidence as outlined by the Australian National Health and Medical Research Council. Stable patients with anterior abdominal stab wounds should be transported to the hospital without delay. Any interventions deemed necessary in prehospital care should be undertaken en route to hospital. In rural hospitals with no on-call surgeon, local wound exploration (LWE) may be undertaken by a general practitioner if confident in this procedure. Otherwise or in the presence of obvious fascial penetration, such as evisceration, the patient should be transferred to the nearest main trauma service for further management. In urban hospitals the patient with omental or bowel evisceration or generalized peritonitis should undergo urgent exploratory laparotomy. Stable patients may be screened using LWE. Abdominal computed tomography scan and plain radiographs are not indicated. Obese and/or uncooperative patients require a general anaesthetic for laparoscopy. If there is fascial penetration on LWE or peritoneal penetration on laparoscopy, then an urgent laparotomy should be undertaken. The developed evidence-based guidelines for stable patients with anterior abdominal stab wounds may help minimize unnecessary diagnostic tests and non-therapeutic laparotomy rates.

Abstract
OBJECTIVE It has been suggested that diagnostic peritoneal lavage is now obsolete in UK hospitals with access to either skilled ultrasonography or emergency physician or surgeon-performed focused abdominal sonography in trauma. Diagnostic peritoneal lavage continues to be advocated and taught on Advanced Trauma Life Support courses. The aim of this study was to evaluate the experiences and attitudes of general-surgery trainees in one UK training region towards diagnostic peritoneal lavage and focused abdominal sonography in trauma in managing blunt abdominal trauma. METHODS An anonymous postal piloted questionnaire was sent to all 66 general surgery specialist trainees in one UK training region between January and March 2005. RESULTS Out of 40 replies to the questionnaire (response rate 61%), 53% and 38% of surgical trainees had either never performed or never observed a diagnostic peritoneal lavage during their training. Thirteen trainees (33%) felt diagnostic peritoneal lavage to be obsolete and would never contemplate using it; 15 trainees (37%) might consider using diagnostic peritoneal lavage if computed tomography or ultrasonography were unavailable. Ten trainees (25%) felt that diagnostic peritoneal lavage had been superseded by computed tomography. Only 12 trainees (30%) had worked in a UK hospital with access to facilities for focused abdominal sonography in trauma and only seven trainees (18%) had received any training or experience in focused abdominal sonography in trauma. CONCLUSIONS Surgical trainees in one UK training region lack skills in both diagnostic peritoneal lavage and focused abdominal sonography in trauma for managing blunt abdominal trauma and are therefore reliant upon the availability of prompt, skilled radiological assistance or emergency physician-provided focused abdominal sonography in trauma.

Abstract
AIM: To retrospectively evaluate the preoperative diagnostic approaches and management of colonic injuries following blunt abdominal trauma.
METHODS: A total of 82 patients with colonic injuries caused by blunt trauma between January 1992 and December 2005 were enrolled. Data were collected on clinical presentation, investigations, diagnostic methods, associated injuries, and operative management. Colonic injury-related mortality and abdominal complications were analyzed.
RESULTS: Colonic injuries were caused mainly by motor vehicle accidents. Of the 82 patients, 58 (70.3%) had other associated injuries. Laparotomy was performed within 6 h after injury in 69 cases (84.1%), laparoscopy in 3 because of haemodynamic instability. The most commonly injured site was located in the transverse colon. The mean colon injury scale score was 2.8. The degree of faecal contamination was classified as mild in 18 (22.0%), moderate in 42 (51.2%), severe in 14 (17.1%), and unknown in 8 (9.8%) cases. Sixty-seven patients (81.7%) were treated with primary repair or resection and anastomosis. Faecal stream diversion was performed in 15 cases (18.3%). The overall mortality rate was 6.1%. The incidence of colonic injury-related abdominal complications was 20.7%. The only independent predictor of complications was the degree of peritoneal faecal contamination (P = 0.02).
CONCLUSION: Colonic injuries following blunt trauma are especially important because of the severity and complexity of associated injuries. A thorough physical examination and a combination of tests can be used to evaluate the indications for laparotomy. One stage management at the time of initial exploration is most often used for colonic injuries.

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 Local stab wound (SW) exploration to assess abdominal fascial integrity is a highly invasive procedure frequently performed under demanding circumstances in the Emergency Department (ED). We hypothesized ultrasound (U/S) may be useful in the detection of fascial defects resulting from anterior abdominal stab injury, eliminating the need for local wound exploration METHODS Thirty-five hemodynamically normal patients evaluated at a Level I trauma center for anterior abdominal stab wounds were examined by U/S (8 mHz probe) for evidence of fascial violation. All patients were subsequently evaluated by local wound exploration RESULTS Fascial U/S had an overall sensitivity of 59% and specificity of 100%, (PPV 100%, NPV 59%) for detection of fascial SW defects compared with local wound exploration. The sensitivity of fascial U/S for stab wound evaluation varied directly with experience of the sonographer CONCLUSIONS A positive fascial U/S obviates the need for invasive SW exploration; however, a negative fascial U/S does not preclude the need for local wound exploration. Resident U/S training for specific penetrating injuries may reduce the need for abdominal SW fascial exploration in the ED.

Abstract
PURPOSE To determine retrospectively the accuracy of screening ultrasonography (US) in patients with hypotension (systolic blood pressure <or= 90 mm Hg) after blunt abdominal trauma. MATERIALS AND METHODS The investigational review board approved the study and waived informed consent. The study group consisted of 128 hypotensive patients with blunt abdominal trauma who underwent screening US over a 9-year period. Abdomens were scanned for free fluid and for parenchymal heterogeneity in visceral organs; scans that depicted these were considered positive. Prospective reports were used to calculate diagnostic performance. Patients were retrospectively given a fluid score according to the number of fluid pockets visualized (0, 1, or > or =2) (consensus by three readers) and were assigned to a low- or high-risk group according to the presence of hematuria and/or axial fracture on radiographs. Screening US results were compared with findings with the best available reference standard (computed tomography [CT]), repeat US, other diagnostic test, laparotomy, autopsy, clinical course). Data were compared by using chi(2) or Fisher exact test, depending on expected frequencies, with Bonferroni correction for multiple comparisons. Continuous variables were compared by using unpaired Student t test or Mann-Whitney U test, depending on data distribution. RESULTS The study included 77 male and 51 female patients (mean age, 42 years). Sensitivity was 85% (44 of 52) for detection of any injuries, 97% (30 of 31) for surgical injuries (ie, injuries requiring surgery), and 100% (10 of 10) for fatal injuries. Specificity was 96% (73 of 76), 82% (80 of 97), and 69% (81 of 118), and accuracy was 91% (117 of 128), 86% (110 of 128), and 71% (91 of 128), for respective injury categories. One nonfatal surgical injury was missed in a high-risk patient. For each injury category, frequency of injury in patients with a fluid score of 2 or more was nine times that in patients with a score of 0 (P < .001 for all comparisons). Frequency of false-negative US findings in high-risk patients was eight times that in low-risk patients (P < .01). CONCLUSION In patients who are hypotensive after blunt abdominal trauma and not hemodynamically stable enough to undergo diagnostic CT, negative US findings virtually exclude surgical injury, while positive US findings indicate surgical injury in 64% of cases.

Abstract
OBJECTIVE To gain an overview of the current practice of different major institutions in Taiwan in the evaluation of abdominal injuries. A further comparison was made between general surgeons and emergency physicians in this aspect. METHOD A telephone survey was conducted of all emergency departments of 58 major institutions (14 medical centres, 44 district hospitals) that are capable of providing definitive care for trauma victims in Taiwan in June 2002. Respondents were asked to select the diagnostic modality of choice in the evaluation of a haemodynamically abnormal blunt trauma victim with suspected intra-abdominal injuries. In the same study period, this particular telephone scenario was also used to survey 109 individual doctors (45 emergency physicians, 64 general surgeons). RESULTS Most respondents preferred ultrasound (also known as focused assessment with sonography for trauma or "FAST") instead of diagnostic peritoneal lavage (DPL) because DPL is invasive and most doctors in Taiwan have limited experience in performing DPL or interpreting the results. CONCLUSIONS It seems reasonable to devote greater resources for emergency departments to incorporate a FAST based algorithm into their initial management of trauma victims, and to improve training in its use. It is also suggested that future ATLS teaching in Taiwan should include didactic material on FAST.

Abstract
OBJECTIVES To evaluate non-radiologist performed emergency ultrasound for the detection of haemoperitoneum after abdominal trauma in a British accident and emergency department. METHODS Focused assessment with sonography for trauma (FAST) was performed during the primary survey on adult patients triaged to the resuscitation room with suspected abdominal injury over a 12 month period. All investigations were performed by one of three non-radiologists trained in FAST. The ultrasound findings were compared against the investigation of choice of the attending surgeon/accident and emergency physician. The patients were followed up for clinically significant events until hospital discharge or death. RESULTS One hundred patients who had sustained blunt abdominal trauma, were evaluated by FAST. Nine true positive scans were detected and confirmed by computed tomography, diagnostic peritoneal lavage, or laparotomy. There was one false positive in this group, giving a sensitivity of 100%, specificity 99%, and positive predictive value of 90%. Ten patients with penetrating injuries were evaluated with a sensitivity and specificity for FAST of 33% and 86% respectively. CONCLUSIONS Emergency torso ultrasound for the detection of haemoperitoneum can be successfully performed by trained non-radiologists within a British accident and emergency system. It is an accurate and rapid investigation for blunt trauma, but the results should be interpreted with caution in penetrating injury.

Abstract
A prospective blinded pilot study was performed at an urban level 1 trauma center to evaluate the efficacy of ultrasound in ruling out penetrating visceral truncal injury. For 8 months, 49 nonconsecutive patients who presented with truncal gunshot and stab wounds were evaluated by a 10-MHz ultrasound tranducer probe. The deepest muscle bundle and the fascia enveloping it was examined by ultrasound. These images were compared to the equivalent contralateral unaffected side of the patient. All the patients then underwent standard testing to evaluate for potential intracavitary injury. Forty-nine patients with a mean age of 28 years (SD, 8.8) were evaluated by ultrasound. A total of 58 injuries were evaluated of which 37 were stab wounds and 21 were gunshot wounds. Thoracoabdominal and back and flank injuries were the most commonly evaluated injuries. There were 20 true positives, 20 false positives, and 18 true negatives, each with approximately twice as many stab as gunshot wounds. There were no false negatives. The sensitivity and negative predictive value of ultrasound in determining clinically significant truncal visceral injury in penetrating truncal trauma is 100 per cent. The specificity and positive predictive value are both approximately 50 per cent. Ultrasonic examination of the injured abdominal wall layers in truncal penetrating trauma is an excellent screening tool. Simple comparative assessment with the unaffected contralateral side allows a highly sensitive method of decreasing the number of potentially morbid, time consuming, and expensive tests that are currently employed to rule out visceral injury.

Abstract
Diagnostic peritoneal lavage (DPL) is one of the most useful tools in the diagnosis of intraperitoneal injuries secondary to stab wounds. The lavage catheter is inserted into the peritoneal cavity through a surgical incision or a blind puncture. Complications related to the catheter insertion were previously reported in both techniques. We describe 2 cases in which the lavage catheter was inserted through the stab wound itself after local wound exploration clearly demonstrated violation of the peritoneum. We suggest that in anterior abdominal stab wounds, the DPL can be safely and effectively performed through the stab wound if penetration to the peritoneum is diagnosed.

Abstract
BACKGROUND The utility of diagnostic peritoneal lavage (DPL) as a diagnostic tool specifically for shotgun wound to the abdomen (SGWA) is unknown. This prospective study was undertaken to determine the sensitivity, specificity, and accuracy of DPL for the detection of intra-abdominal injuries following SGWA. METHODS DPL was performed on all patients sustaining SGWA who lacked a clear indication for laparotomy. Patients exceeding 10,000 red blood cells (RBC)/mm were taken for exploratory laparotomy. A prospective database was kept with information on wound location, DPL result, findings upon laparotomy and outcome. RESULTS Thirty-two DPLs were performed at our urban Level I trauma center for SGWA. Of these, 8 patients had a positive DPL. Upon laparotomy, 7 patients were found to have intra-abdominal injuries, 6 of which required surgical intervention. One patient had no peritoneal penetration or intra-abdominal injury. Of the 24 patients that had a negative DPL, 1 subsequently developed indications for laparotomy and was found to have operative injuries. For predicting intra-abdominal injuries DPL has a sensitivity, specificity and accuracy of 87.5%, 95.8% and 93.8%, respectively. CONCLUSION For patients presenting with SGWA who do not present with indications for immediate laparotomy, DPL is a reliable indicator of intra-abdominal injury and need for operative intervention.

Abstract
OBJECTIVES Diagnostic peritoneal lavage (DPL) is used to detect intraperitoneal bleeding in patients sustaining blunt and penetrating abdominal trauma. The procedure should be performed by an experienced general surgeon, and the fluid obtained analysed by haematology technicians. Current Advanced Trauma Life Support guidelines are very clear on what constitutes a positive result, mandating laparotomy. The aim of this work was to assess whether DPL could actually be performed in practice. METHODS A telephone survey was performed of a random selection of haematology technicians in 40 major trauma units in the UK, to assess whether they could actually analyse a DPL sample if it were sent to them. This was performed both during the day, and "out of hours". Secondly the experience of performing DPL was determined among 1797 general surgical trainees and consultants, by means of a questionnaire. RESULTS Between 9 am and 5 pm 29 of 40 haematology technicians questioned were able to analyse a sample of DPL fluid. This compared with a figure of 9 of 40 when the questionnaire was administered "out of hours". A total of 854 (48%) questionnaires were received from surgical trainees and consultants. Approximately 60% of those questioned had performed less than 10 DPLs throughout the whole of their careers. DISCUSSION These results suggest that UK surgeons have little experience in performing DPL, and even if they do it is unlikely that any haematology departments will be able to analyse the sample, especially if performed after 5 pm. ATLS guidelines should be changed, and this investigation abandoned in favour of abdominal ultrasound.
