Abstract
This is a recommended management algorithm from the Western Trauma Association addressing the management of adult patients with abdominal stab wounds. Because there is a paucity of published prospective randomized clinical trials that have generated Class I data, these recommendations are based primarily on published observational studies and expert opinion of Western Trauma Association members. The algorithm and accompanying comments represent a safe and sensible approach that can be followed at most trauma centers. We recognize that there will be patient, personnel, institutional, and situational factors that may warrant or require deviation from the recommended algorithm. We encourage institutions to use this as a guideline to develop their own local protocols.

Abstract
In cases of inflicted injury, the process of examining the patient for external injuries and documenting the findings is important for forensic assessment, including estimating or determining the type of weapon used and the circumstances of the violence. However, external examination is obviously limited in assessing internal injury. Here, we report the cases of two patients who survived stab wounds, where the findings of contrast-enhanced computed tomography (CT) performed for clinical diagnosis in the hospital were useful for forensic injury evaluation. In both cases, contrast-enhanced CT clearly displayed the injuries to the parenchymal organs and enabled the estimation of the direction and depth of the stab wounds by depicting the track and base of the wounds on acquired images. With the addition of the findings from examination of the external wound, the stab wounds in both victims were consistent with injury caused by the suspected weapon. Recently, imaging modalities including CT have become useful supplemental tools for precise forensic evaluation. Imaging findings obtained from these modalities could especially provide useful information for forensic assessment in clinical forensic medicine because examination of internal injury in the living body cannot generally be performed. Research on the precise diagnostic value of this method is required to utilize this method adequately in clinical forensic medicine.

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

Abstract
Nonoperative management of both blunt and penetrating injuries can be challenging. During the past three decades, there has been a major shift from operative to increasingly nonoperative management of traumatic injuries. Greater reliance on nonoperative, or "conservative" management of abdominal solid organ injuries is facilitated by the various sophisticated and highly accurate noninvasive imaging modalities at the trauma surgeon's disposal. This review discusses selected topics in nonoperative management of both blunt and penetrating trauma. Potential complications and pitfalls of nonoperative management are discussed. Adjunctive interventional therapies used in treatment of nonoperative management-related complications are also discussed. REPUBLISHED WITH PERMISSION FROM Stawicki SPA.

Abstract
INTRODUCTION The selective non-operative management (SNOM) of stab injuries of the anterior abdomen is well established, but its application to the posterior abdomen remains controversial. MATERIALS AND METHODS A retrospective review of 1013 patients was undertaken at a major trauma service in South Africa over a five-year period. RESULTS Ninety per cent of patients were males, and the mean age was 25 years. The mean time from injury to presentation was 4h and 73% of all injuries were inflicted by knives. A total of 9% (93) of patients required a laparotomy [Group A] and 82% (833) were successfully observed without the need for operative intervention [Group B]. CT imaging was performed on 52 patients (5%) who had haematuria [Group C], 25 (3%) who had neurological deficits [Group D], and 10 (1%) with retained weapon injuries [Group E]. The accuracy of physical examination for identifying the presence of organ injury was 88%. All observed patients who required laparotomy declared themselves within 24h. There were no mortalities as direct result of our current management protocol. CONCLUSIONS Selective management based on active clinical observation and serial physical examination is safe, and when coupled with the judicious use of advanced imaging, is a prudent and reliable approach in a resource constrained environment.

Abstract
INTRODUCTION The spectrum of injury associated with anterior abdominal stab wounds (SWs) is well established. The literature on the spectrum of organ injury associated with SWs to the posterior abdomen, however, is limited. METHODS We reviewed our experience of 105 consecutive patients who had established indications for laparotomy managed over a 4-year period in a high volume trauma service in South Africa. RESULTS Of the 105 patients, 97 (92%) were male and the overall mean age was 24 years. Fifty-seven patients (54%) had immediate indications for laparotomy. The remaining 48 patients (46%) initially underwent active clinical observation and the indications for laparotomy became apparent during the observation period. Of the 105 laparotomies performed, 94 (90%) were positive and 11 (10%) were negative. Of the 94 positive laparotomies, 92 were therapeutic and 2 were non-therapeutic. A total of 176 organ injuries were identified: 50 (53%) of the 94 patients sustained a single organ injury while the remaining 44 (47%) sustained multiple organ injuries. The most commonly injured organs were the colon (n=63), spleen (n=21) and kidney (n=19). CONCLUSIONS The pattern of intra-abdominal injuries secondary to SWs to the posterior abdomen is different to that seen with the anterior abdomen. Colonic injury is most commonly encountered, followed by injuries to the spleen and kidney. Clinicians must remain vigilant because of the potential for occult injuries.

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

Abstract
The selective non-operative management of penetrating abdominal injury is gaining increasing acceptance. Recognition of the morbidity, mortality, and cost associated with non-therapeutic exploration has provided the impetus for selective management. This review describes the principles of, and evidence for, this strategy. Selective management is widely accepted for the treatment of stab wounds, but the selective management of ballistic injuries, particularly in the military setting, remains contentious. As a result, there are marked variations in the application of this practice. Computed tomography is a prerequisite for the selective management of ballistic injuries, and possibly also stab wounds. Failure of non-operative management, following stab wounds or gunshot wounds, is invariably apparent within 24 hours.

Abstract
BACKGROUND : Although there is no debate that patients with peritonitis or hemodynamic instability should undergo urgent laparotomy after penetrating injury to the abdomen, it is also clear that certain stable patients without peritonitis may be managed without operation. The practice of deciding which patients may not need surgery after penetrating abdominal wounds has been termed selective management. This practice has been readily accepted during the past few decades with regard to abdominal stab wounds; however, controversy persists regarding gunshot wounds. Because of this, the Eastern Association for the Surgery of Trauma Practice Management Guidelines Committee set out to develop guidelines to analyze which patients may be managed safely without laparotomy after penetrating abdominal trauma. A secondary goal of this committee was to find which diagnostic adjuncts are useful in the determination of the need for surgical exploration. METHODS : A search of the National Library of Medicine and the National Institutes of Health MEDLINE database was performed using PubMed (www.pubmed.gov). RESULTS : The search retrieved English language articles concerning selective management of penetrating abdominal trauma and related topics from the years 1960 to 2007. These articles were then used to construct this set of practice management guidelines. CONCLUSIONS : Although the rate of nontherapeutic laparotomies after penetrating wounds to the abdomen should be minimized, this should never be at the expense of a delay in the diagnosis and treatment of injury. With this in mind, a routine laparotomy is not indicated in hemodynamically stable patients with abdominal stab wounds without signs of peritonitis or diffuse abdominal tenderness. Likewise, it is also not routinely indicated in stable patients with abdominal gunshot wounds if the wounds are tangential and there are no peritoneal signs. Abdominopelvic computed tomography should be considered in patients selected for initial nonoperative management to facilitate initial management decisions. The majority of patients with penetrating abdominal trauma managed nonoperatively may be discharged after 24 hours of observation in the presence of a reliable abdominal examination and minimal to no abdominal tenderness. Diagnostic laparoscopy may be considered as a tool to evaluate diaphragmatic lacerations and peritoneal penetration in an effort to avoid unnecessary laparotomy.

Abstract
BACKGROUND Stab wounds to the back and flank infrequently cause injuries requiring operative treatment. Triple-contrast CT scan (3CT) has essentially replaced diagnostic peritoneal lavage (DPL) as the primary means of identifying patients who require operative intervention. This study aims to review the evolution of the diagnostic work-up for stab wounds to the back and flank. METHODS We performed a retrospective review of haemodynamically stable patients with stab wound to the back or flank treated at a single Level 1 trauma centre over a 10-year period. Diagnostic accuracy of DPL and 3CT screening tests were evaluated against the patient's subsequent clinical course. The elapsed time between emergency department (ED) presentation and test results was recorded and compared. RESULTS A total of 177 patients were identified. 76 patients had stab wounds isolated to the back, 90 had stab wounds isolated to the flank and 11 had wounds in both locations. CT ultimately became the predominant initial diagnostic test during the study period. Although less frequently used over time, DPL retained good sensitivity and specificity for injuries requiring operative intervention (92% and 83%, respectively). 3CT identified all injuries requiring laparotomy (100% sensitivity) and had a specificity of 96%. 3CT was a more time-consuming process, with results available at a median of 3:31h after arrival to the ED, as compared to 1:03h for DPL (p<0.01). CONCLUSIONS 3CT diagnosed all injuries requiring operative intervention, and its use was associated with a lower rate of non-therapeutic laparotomies. However, average time to diagnosis by 3CT was prolonged compared to DPL. Although 3CT has become the predominant diagnostic test when evaluating patients with stab wounds to the back and flank at our institution, efforts to further expedite the diagnostic work-up are necessary.

Abstract
We present our experience during the past 5 years with isolated penetrating flank trauma. We examined the evaluation process, treatment plan, length of stay, outcome, and complications of patients with isolated penetrating injuries to the flank. There were four patient groups: 1) laparotomy (n = 5); 2) local wound exploration (n = 1); 3) laparoscopy (n = 8); and 4) observation and triple contrast CT scan (n = 9). All patients were male. The mean length of stay was 15 days for group 1, one day for group 2, two days in group 3, and 1.5 days in group 4. Three patients had diaphragmatic injuries, which were repaired laparoscopically. One patient with local wound exploration re-presented with a diaphragm hernia. A negative triple contrast CT scan resulted in no subsequent intervention. There were no missed injuries or complications from CT scan + observation or from diagnostic laparoscopy. We believe that laparoscopy may emerge as a useful adjunct in the treatment of patients with flank trauma. We present an algorithm for the management of penetrating flank trauma.

Abstract
PURPOSE To assess the accuracy of computed tomography (CT) in demonstrating the presence or absence of peritoneal violation and type of intraperitoneal organ injury, if any, in hemodynamically stable patients with penetrating torso trauma but without definite peritoneal signs or radiographic evidence of free intraperitoneal air. MATERIALS AND METHODS During a 29-month period, helical CT with oral, rectal, and intravenous contrast material (triple-contrast) was performed in 200 hemodynamically stable patients, including 169 men (age range, 15-85 years; mean age, 31 years) and 31 women (age range, 17-45 years; mean age, 28 years) with penetrating torso trauma. The study group included 86 patients with gunshot wounds, 111 with stab wounds, and three impaled by sharp objects. CT scans were evaluated prospectively by three trauma radiologists for evidence of peritoneal violation to determine injury to intra- or retroperitoneal solid organs, bowel, mesentery, vascular structures, diaphragm, and urinary tract. Sensitivity, specificity, and accuracy of CT in the diagnosis of peritoneal violation were determined. RESULTS CT findings aided diagnosis of peritoneal violation in 34% of patients (68 of 200) and were negative for peritoneal violation in 66% of patients (132 of 200). Two patients with negative CT findings failed to improve with observation and underwent therapeutic laparotomy. CT had 97% sensitivity (66 of 68 findings), 98% specificity (130 of 132 findings), and 98% accuracy (196 of 200 findings) for peritoneal violation. CT aided diagnosis of 28 hepatic, 34 bowel or mesenteric, seven splenic, and six renal injuries. Laparotomy based on CT findings in 38 patients was considered therapeutic in 87% (33 of 38) and nontherapeutic in 8% (three of 38) and had negative results in 5% (two of 38). CONCLUSION Triple-contrast helical CT accurately demonstrates peritoneal violation and visceral injury in patients with penetrating torso wounds.

Abstract
Mandatory surgical exploration for gunshot wounds to the abdomen has been a surgical dictum for the greater part of this past century. Although nonoperative management of blunt solid organ injuries and low-energy penetrating injuries such as stab wounds is well established, the same is not true for gunshot wounds. The vast majority of patients who sustain a gunshot injury to the abdomen require immediate laparotomy to control bleeding and contain contamination. Nonoperative treatment of patients with a gunshot injury is gaining acceptance in only a highly selected subset of hemodynamically stable adult patients without peritonitis. Although the physical examination remains the cornerstone in the evaluation of patients with gunshot injury, other techniques such as computed tomography, diagnostic peritoneal lavage, and laparoscopy allow accurate determination of intra-abdominal injury. The ability to exclude internal organ injury nonoperatively avoids the potential complications of unnecessary laparotomy. Clinical data to support selective nonoperative management of certain gunshot injuries to the abdomen are accumulating, but the approach has risks and requires careful collaborative management by emergency physicians and surgeons experienced in the care of penetrating injury.

Abstract
BACKGROUND The optimal strategy for identifying patients with abdominal stab wounds requiring surgical repair has not been defined. The potential benefits of diagnostic laparoscopy by incorporating it into the routine diagnostic workup of patients with anterior abdominal stab wounds was evaluated in a two-layer, randomized study. METHODS From May 1997 through January 2002, stable patients without peritonitis but with demonstrated peritoneal violation were randomized (A) to exploratory laparotomy (AEL) (n = 23) or diagnostic laparoscopy (ADL) (n = 20). Simultaneously, patients with equivocal peritoneal violation on local wound exploration were randomized (B) to diagnostic laparoscopy (BDL) (n = 28) or expectant nonoperative management (BNOM) (n = 31). Hospital morbidity, length of stay, and costs were primary endpoints, with postdischarge disability being a secondary endpoint. RESULTS In patients with peritoneal penetration (AEL vs. ADL), there were minimal differences in the therapeutic operation rate (8 of 23 [AEL] vs. 8 of 20 [ADL], p = 0.761), mortality (none), morbidity (3 of 23 vs. 2 of 20, p = 0.999), hospital stay (mean +/- SD) (5.7 +/- 2.5 vs. 5.1 +/- 4.0 days, p = 0.049), hospital costs (4.6 +/- 1.3 vs. 4.8 +/- 1.9 x 1,000 EUR, p = 0.576), and length of sick leave (34 +/- 12 vs. 29 +/- 11 days, p = 0.305). In patients with equivocal peritoneal penetration (BDL vs. BNOM), laparoscopy found more mostly minor organ injuries (7 of 28 [BDL] vs. 1 of 31 [BNOM], p = 0.022) with no significant difference in therapeutic operations (3 of 28 vs. 1 of 31, p = 0.337) or morbidity (3 of 28 vs. 0 of 31, p = 0.101), but was associated with increased length of stay (2.6 +/- 2.1 vs. 1.9 +/- 1.8 days, p = 0.022), hospital costs (4.2 +/- 1.3 vs. 1.5 +/- 1.1 x 1,000 EUR, p = 0.000), and sick leave requirements (18 of 23 vs. 8 of 28 of eligible patients, p = 0.001). CONCLUSION In patients with demonstrated peritoneal violation, laparoscopy offers little benefit over exploratory laparotomy. In patients with equivocal peritoneal penetration on local wound exploration, laparoscopy detects more mostly minor organ injuries than expectant nonoperative management but is associated with increased hospital stay, costs, and sick leave requirements. Overall, diagnostic laparoscopy cannot be recommended as a routine diagnostic tool in anterolateral abdominal and thoracoabdominal stab wounds.

Abstract
OBJECTIVE A prospective study was performed to determine the usefulness of triple-contrast helical CT in predicting peritoneal violation and the need for laparotomy in the treatment of penetrating torso trauma. SUBJECTS AND METHODS Triple-contrast helical CT scans were obtained in 104 hemodynamically stable patients with penetrating injuries to the torso (thoracoabdominal region including tangential wounds to the anterior abdomen, flank, back, and pelvis) over a 17-month period. The study group included 54 patients with gunshot wounds and 50 with stab wounds. No patient had a radiographic or clinical indication for immediate laparotomy. A positive finding on CT was defined as evidence of peritoneal violation or injury to the retroperitoneal colon, major vessel, or urinary tract. Patients with a positive CT, except patients with isolated liver injury or free fluid, underwent laparotomy. Patients with a negative finding on CT were initially observed. RESULTS CT studies were positive in 35 (34%) of 104 patients and negative in 69 (66%) of 104 of patients. Laparotomy was performed in 21 (60%) of 35 patients with positive CT; 19 (86%) of 22 were therapeutic, two (9%) were nontherapeutic, and one (5%) was negative (no injury was found). Nine patients with isolated hepatic injuries were successfully treated without laparotomy. Among patients with a negative CT, 67 (97%) of 69 were treated nonoperatively with success. CT had 100% (19/19) sensitivity, 96% (69/72) specificity, 100% (69/69) negative predictive value, and 97% (101/104) accuracy in predicting the need for laparotomy. CONCLUSION Triple-contrast helical CT can accurately predict the need for laparotomy and exclude peritoneal violation in penetrating torso trauma including tangential abdominal wounds.

Abstract
BACKGROUND Focused Assessment with Sonography for Trauma (FAST) is rapidly establishing its place in the evaluation of blunt abdominal trauma. However, no prospective study specifically evaluates its role in penetrating abdominal trauma. METHODS Data were collected prospectively in 75 consecutive stable patients with penetrating trauma to the abdomen, flank, or back, from December 1998 to June 1999. Those with an obvious need for emergent laparotomy were excluded. FAST was performed as the initial diagnostic study on all patients. Wound location, type of weapon, and findings of diagnostic peritoneal lavage, triple-contrast computed tomographic scan, or laparotomy were recorded. The presence of peritoneal blood was noted. Data were analyzed using the chi(2) test. RESULTS Of the 75 patients, there were 32 stab and 43 gunshot wounds. There were 66 male patients and 9 female patients; the mean age was 30 years; 41 had proven abdominal injury and 34 had no injury; and 21 patients had a positive FAST. Nineteen had peritoneal blood and injuries requiring repair at the time of laparotomy. There were two false-positive studies. Fifty-four patients had a negative FAST. In 32 patients, this was a true-negative study. Thirteen patients had a false-negative FAST and had peritoneal blood and significant injury on further evaluation. Nine patients had a negative FAST and no peritoneal blood but still had abdominal injuries requiring operative repair, including liver (four), small bowel (four), diaphragm (three), colon (three), and stomach (one). The overall sensitivity of FAST was 46% and the specificity was 94%. The positive predictive value was 90%, and the negative predictive value was 60%. CONCLUSION FAST can be a useful initial diagnostic study after penetrating abdominal trauma. A positive FAST is a strong predictor of injury, and patients should proceed directly to laparotomy. If negative, additional diagnostic studies should be performed to rule out occult injury.

Abstract
An EDOU may be an ideal setting for the short-term monitoring and treatment of certain acutely injured patients. The patients choosen for observation, and the diagnostic studies used, will be specific to a particular institution's availability and expertise. Pathways should be developed in conjunction with all services caring for these patients.

Abstract
Triple-contrast computerized tomography OCT) has been proposed as a method to detect high-risk injuries in hemodynamically stable patients with stab wounds (SWs) to the back/flank and to successfully triage patients with low-risk scans into a potentially cost-effective treatment algorithm. The purpose of this study was to retrospectively review our experience with the use of 3CT for diagnostic accuracy of SWs to the back/flank and to evaluate potential decreased length of stay (LOS) in the hospital for patients with low-risk scans and no associated injuries. Seventy-nine hemodynamically stable patients met criteria for inclusion in this review. Fifty-eight 3CTs were performed for initial evaluation, 44 low risk and 14 high risk, and 21 patients underwent mandatory laparotomy. The accuracy of 3CT was found to be 97.9 per cent. The LOS was significantly less in patients who had no associated injuries and a low-risk 3CT (16.5 hours), as compared with all other treatment groups. Hemodynamically stable patients with SWs to the back/flank may be safely triaged using 3CT. Patients with low-risk scans and no associated injuries may be discharged immediately, and those with potential delayed associated injuries should be observed for 6 to 24 hours. This strategy significantly decreases LOS in patients with low incidence of significant injury.

Abstract
The management of stab wounds to the back is controversial. There are certain clear indications for exploratory laparotomy, but most cases require a diagnostic workup and a period of observation. In this article, different diagnostic modalities are presented, including local wound exploration, diagnostic peritoneal lavage, abdominal computed tomography (CT) scan, triple-contrast abdominal CT scan, and intravenous pyelography (IVP). Recommendations for management are given, with emphasis on abdominal CT scan and observation.

Abstract
OBJECTIVE To determine whether computed tomography (CT) is an accurate diagnostic modality for the triage of hemodynamically stable patients with gunshot wounds of the abdomen and flank. METHODS A chart review of 83 trauma patients for whom abdominal CT was used as initial screening. RESULTS In 53 patients, CT revealed no evidence of peritoneal penetration, and in 15 patients, there was evidence of either peritoneal penetration or liver injury. There were no false results in these patients. Among 15 patients with questionable peritoneal penetration, cavitary endoscopy was performed in 11 and exploratory laparotomy was performed in 3, and 1 patient was initially observed and subsequently underwent exploratory surgery for a missed colonic injury. CONCLUSION In selected centers and in hemodynamically stable patients with abdominal and flank gunshot wounds, abdominal CT can be an effective and safe initial screening modality to document the presence or absence of peritoneal penetration and to manage nonoperatively stable patients with liver injuries. If there is any question of peritoneal penetration, cavitary endoscopy should be part of the protocol of nonoperative management.
