Selective Nonoperative Management in 1106 Patients With Abdominal Gunshot Wounds: Conclusions on Safety, Efficacy, and the Role of Selective CT Imaging in a Prospective Single-center Study

Management of penetrating splenic trauma; is it different to the management of blunt trauma?

PURPOSE

We compare the treatment and outcomes of penetrating and blunt splenic trauma at Major Trauma Centres (MTC) within the UK.

METHODS

Data obtained from the national Trauma Audit Research Network database identified all eligible splenic injuries admitted to MTC within England between 01/01/17-31/12/21. Demographics, mechanism of injury, splenic injury classification, associated injuries, treatment, and outcomes were compared.

RESULTS

Penetrating injuries accounted for 5.9 % (235/3958) of splenic injuries, compared to blunt at 94.1 % (3723/3958). Most penetrating injuries (91.5 %, 215/235) resulted from stabbing. There was a statistically significant difference in first treatment between penetrating and blunt splenic injuries (p < 0.001), but similar trends between GSW and stab injuries. Most penetrating injuries were managed conservatively (68.9 %,162/235), with 10.6 % (25/235) embolized compared to 13.2 % (491/3723) for blunt splenic injury. More penetrating injuries (20.4 %, 48/235) underwent splenectomy compared to blunt injuries (8.8 %, 326/3723). Those receiving embolization after penetrating trauma had an 8.0 % (2/25) 30-day mortality compared with blunt at 8.6 % (42/491) and compared with 2.1 % (1/48) and 12.3 % (40/326) of those who received splenectomy in the penetrating and blunt groups, respectively. 8 out of the 25 penetrating trauma patients who underwent embolisation (32.0 %) required splenectomy due to embolisation failure compared to 5.3 % (26/491) in the blunt trauma group.

CONCLUSION

A trend is seen towards the use of operative management in penetrating splenic trauma. There is a high splenic embolisation failure rate (32.0 %) in penetrating trauma although mortality for those embolised was similar to the blunt injury group.

Splenectomy versus angioembolization for severe splenic injuries in a national trauma registry: To save, or not to save, the spleen, that is the question

BACKGROUND

The use of angioembolization as a first approach for treating severe, blunt splenic injuries has increased recently, yet evidence showing its superiority to immediate splenectomy is lacking. We compared the prognosis of angioembolization versus splenectomy in patients presenting hemodynamically unstable with high-grade, image-confirmed, blunt splenic injuries in a nationally representative dataset.

METHODS

We queried the 2017-2022 Trauma Quality Improvement Program database for adults with blunt splenic injury abbreviated injury scale = 4-5, with arrival systolic blood pressure <90 mm Hg, and treated with either angioembolization or splenectomy <6 hours of arrival after a computed tomography scan. Entropy balancing was used to adjust for confounders.

RESULTS

Of 1,360 patients, 328 (24.1%) underwent angioembolization and 1,032 (75.9%) splenectomy. Treatment with angioembolization first was more likely in recent years, in level 1 trauma centers, for less severe spleen injuries, in the absence of head injuries. Angioembolization and splenectomy had similar entropy balancing-adjusted survival (entropy balancing hazard ratio = 1.02; 95% confidence interval: 0.97-1.07, P = .49). One-fifth of those with angioembolization first required rescue splenectomy <6 hours, mostly those with spleen injury grade 5 and additional abdominal injuries. Although this resulted in worse survival (hazard ratio: 1.12; 95% confidence Interval: 0.99-1.26) than successful angioembolization, the survival was not significantly worse than those treated with splenectomy first (entropy balancing hazard ratio: 1.07; 95% confidence Interval: 0.96-1.20).

CONCLUSION

Angioembolization was associated with similar survival to splenectomy first for patients arriving hypotensive with severe, image-confirmed blunt splenic injuries, suggesting that it was an appropriate treatment decision. Although survival was worse after failed angioembolization than after successful angioembolization, it was not worse than splenectomy first, suggesting that the attempt to preserve the spleen was justified.

Computed tomography in initially unstable thoracoabdominal trauma can safely enhance triage

Introduction

Computed tomography (CT) imaging of hemodynamically abnormal trauma patients undergoing aggressive resuscitation is controversial. Our study investigated outcomes for hemodynamically abnormal thoracoabdominal trauma undergoing CT prior to definitive therapy.

Methods

Hemodynamically abnormal (HR≥120 bpm, SBP<90 mmHg) patients arriving to our Level I trauma center between 2015 and 2022 were reviewed. Patients with thoracoabdominal trauma achieving hemodynamic improvement (SBP≥90 mmHg) were included. Pediatric patients, pregnant patients, and traumatic arrests were excluded. After matching for baseline characteristics, CT findings, and operative details, clinical outcomes were tabulated. Primary outcomes included hospital length of stay (HLOS), intensive care unit length of stay (ICU LOS), ventilator days and mortality. Secondary outcomes included intraoperative data, transfusions, additional procedures, and complications.

Results

A total of 235 patients met inclusion criteria. Thirty-six (15 %) were triaged directly to the OR while 199 (85 %) went to CT. The CT and OR groups were matched for injury burden (mean ISS OR group=21±2.6 vs. CT group=18.4 ± 0.8, p = 0.24). Overall, no difference in HLOS (p = 0.3), ICU LOS (p = 0.9), time on ventilator (p = 0.4) or mortality (p = 0.5) was observed. Patients undergoing CT needed less PRBCs (9.0 ± 2.6 vs. 3.4 ± 0.7 units) and FFP (5.1 ± 1.9 vs. 1.6 ± 0.4 units). The OR group patients had a higher probability of needing to undergo additional procedures (36 % vs. 12 %).

Conclusion

Hemodynamically abnormal thoracoabdominal trauma patients who are resuscitated to a SBP≥90 mmHg can safely undergo CT prior to definitive therapy.

Evolution in liver trauma management: a single centre experience

OBJECTIVES

Liver trauma is common and can be treated non-operatively, through radiological embolisation, or surgically. Non-operative management (NOM) is preferred when possible, but specific criteria remain unclear. This retrospective study at a level I trauma centre assessed the evolution and outcomes of liver injury management over more than 20 years.

METHODS

Data from January 1996 to June 2020 were analysed for liver trauma cases. Variables were evaluated, including the type of injury, diagnostic modalities, liver injury grade, transfer from other hospitals, treatment type, and length of hospital stay. Outcomes were assessed using soft (hospitalisation time and intensive care unit stay) and hard (mortality) endpoints.

RESULTS

In total 406 patients were analysed, of which 375 (92.4%) had a blunt and 31 (7.6%) a penetrating liver trauma. Approximately one-third (31.2%) were hemodynamically unstable, although 78.8% had low-grade liver lesions. The initial treatment was non-operative in 72.9% of the patients (68.5% conservative, 4.4% interventional radiology). Blunt trauma was treated by surgery in 23.2% of the patients, while 74.2% in case of penetrating trauma. Overall mortality was 11.1% including death caused by associated lesions. The 24-h mortality was 5.7%. Indication for surgical treatment was determined by hemodynamic instability, high grade liver lesion, penetrating trauma, and associated lesions.

CONCLUSIONS

Although the role of surgery in liver trauma management has strongly diminished over recent decades, hemodynamically unstable patients, high-grade lesions, penetrating trauma, and severe associated lesions are the main indications for surgery. In other situations, NOM by full conservative therapy or radiological embolisation seems effective.

AAST grade of liver injury is not the single most important consideration in decision making for liver trauma

BACKGROUND

The liver is one of the most injured organs in both blunt and penetrating trauma. The aim of this study was to identify whether the AAST liver injury grade is predictive of need for intervention, risk of complications and mortality in our patient population, and whether this differs between blunt and penetrating-trauma mechanisms.

METHODS

Retrospective review of all liver injuries from a single high-volume metropolitan trauma centre in South Africa from December 2012 to January 2022. Inclusion criteria were all adults who had sustained traumatic liver injury. Patients were excluded if they were under 15 years of age or had died prior to operation or assessment. Statistical analysis was undertaken using both univariate and multivariate models.

RESULTS

709 patients were included, of which 351 sustained penetrating and 358 blunt trauma. Only 24.3 % of blunt compared to 76.4 % of penetrating trauma patients underwent laparotomy (p< 0.001). In blunt trauma, increasing AAST grade correlated directly with rates of laparotomy with an odds ratio of 1.7 (p < 0.001). In penetrating trauma, there was no statistical significance between increasing AAST grade and the rate of laparotomy. The rate of bile leak was 4.5 % (32/709) and of rebleed was 0.7 % (5/709). Five patients underwent ERCP and endoscopic sphincterotomy for bile leak, and three required angio-embolization for rebleeding. Increasing AAST grades were significantly associated with the odds of bile leak in both blunt and penetrating trauma. There was a statistically significant increase in the odds of a rebleed with increasing AAST grade in penetrating trauma. Five patients rebled, of which three died. Seven patients developed hepatic necrosis. Seventy-six patients died (10 %). There were 34/358 (9 %) deaths in the blunt cohort and 42 /351 (11 %) deaths in the penetrating trauma cohort.

CONCLUSION

AAST grade in isolation is not a good predictor of the need for operation in hepatic trauma. Increasing AAST grade was not found to correlate with increased risk of mortality for both blunt and penetrating hepatic trauma. In both blunt and penetrating trauma, increasing AAST grade is significantly associated with increased bile leak. The need for ERCP and endoscopic sphincterotomy to manage bile leak in our setting is low. Similarly, the rate of rebleeding and of angioembolization was low.

Outcomes of Nonoperative Management of Penetrating Abdominal Trauma Injury: A Retrospective Study

BACKGROUND

The treatment of penetrating abdominal injuries has changed in recent years with more focus on "nonoperative management" (NOM) to avoid unnecessary laparotomies while identifying injuries early. Although the NOM approach is widely used for stab wounds, its effectiveness in managing abdominal gunshot wounds is controversial. NOM of penetrating abdominal injuries is becoming more dependent on hemodynamic stability and improved noninvasive radiological interventions. The role of NOM is significantly underreported and underestimated in developing countries, particularly in fragile and conflict-affected states such as Yemen. The present study aims to evaluate the clinical outcomes of NOM in penetrating abdominal trauma injury patients and identify factors associated with NOM failure in a low-resource setting.

METHODS

A retrospective study from January 2021 to December 2022 including patients diagnosed with penetrating abdominal trauma at the General Military Hospital, Sana'a, Yemen, was conducted. Hemodynamically stable patients without peritonitis or clear indications for immediate laparotomy were candidates for NOM and were included in the study. Patients with blunt abdominal injuries, penetrating wounds outside the abdomen, particularly head injury, eviscerated structures, and gastrointestinal hemorrhage, or those pronounced dead on arrival were excluded. The primary outcome was the success and failure rate of NOM necessitating laparotomy. The secondary outcome was the factors associated with NOM failure.

RESULTS

During the study, 256 patients with penetrating abdominal injury were admitted, with 222 (86.7%) undergoing immediate laparotomy and 34 (13.3%) treated with NOM. The mean age was 27.6±7.4 years. Bump explosions, mostly sharp objects (secondary blast injuries), were the main causes of injury (n=18, 52.9%). Other causes were low-velocity gunshot wounds, stab wound injuries, and shotgun injuries in 14 (41.2%), one (2.9%), and one (2.9%), respectively. The majority of patients (n=25, 55.9%) were admitted within 6-24 hours of the incident. The abdominal computed tomography (CT) scan revealed various injuries in all patients, including hemoperitoneum in 11 (32.4%), pneumoperitoneum in five (14.7%), liver injury in 15 (44.1%), foreign body attached to the wall colon in 23 (67.6%), kidney injury in two (5.9%), and splenic injury in one (2.9%). NOM was successful in 31 (91.2%) patients. NOM failed in three (8.8%). One patient was treated via the laparoscopic procedure, and two patients were treated with laparotomy procedures. Five (14.7%) cases required intensive care unit (ICU) admission, with no deaths or major complications. In univariate analysis, the presence of free intra-abdominal fluid (pneumoperitoneum) on the initial CT scan and the need for ICU admission were associated with NOM failure and were statistically significant (p<0.05).

CONCLUSION

Our findings support that some penetrating abdominal trauma patients can benefit from NOM. The goal of preventing unnecessary laparotomies should be aligned with a comprehensive comprehension of the clinical signs and symptoms of NOM failure and the necessity for surgical intervention. Serial abdominal examinations remain the foundation of selected NOM; nevertheless, radiological and laboratory tests can be important tools in decision-making. In this study, free intra-abdominal fluid on the initial CT scan and the need for ICU admission were associated with NOM failure.

Abdominal versus pelvic gunshot injuries in terms of postoperative outcomes: A cohort representing the experience of 406 cases in seven years

Objectives

Gunshot injuries have become a significant problem globally. This study aimed to assess the differences between abdominal versus pelvic gunshot injuries in terms of postoperative outcomes to determine which type of injury is more lethal.

Material and Methods

This was a cohort study carried out to compare patients who had abdominal versus pelvic gunshot injuries, to analyse the differences in the impact of the anatomical site of injury on morbidity, mortality, and disabilities in all patients who had been admitted to the hospital due to torso gunshot injuries from February 2011 to December 2018.

Results

During the study period, 406 patients suffered from torso gunshot injuries. 391 were males and 15 were females; 343 (84.4%) patients had abdominal gunshot wounds, which were considered the first group, while in the second group, there were 63 (15.6%) patients who had pelvic gunshot wounds In the first group, 328 (95.6%) patients required urgent explorative laparotomy, complications were observed in 83 (24.2%) patients, while re-operations were reported in 51 (14.9%) patients and 11 (3.2%) patients had permanent functional disabilities, and 46 (13.4%) patients passed away. In the second group, all patients were treated with urgent explorative laparotomy, 17 (27%) patients suffered from complications, re-operation occurred in 13 (20.6%) patients, permeant functional disability occurred in 17 (27%) patients, and mortality was seen in 16 (25.4%) patients.

Conclusion

Our clinical experience has shown that mortality rates and long-term disability occur at a higher rate in pelvic gunshot injuries therefore early senior surgeon input is mandatory for the potential poor outcome to be minimized.

Outcomes of selective non-operative management in adults with abdominal gunshot wounds: a systematic review and meta-analysis

BACKGROUND AND AIMS

Abdominal gunshot wounds (GSWs), a clinically devastating injury, can result in a variety of severe and lethal complications. Traditionally, exploratory laparotomy is the first-line approach for the management of abdominal GSWs, but it is associated with a considerable amount of unnecessary surgeries. At present, selective non-operative management (SNOM) of abdominal GSWs is becoming an effective and well-recognized approach, but it remains widely disputed since many surgeons are skeptical about the validity of SNOM in clinical practice. This meta-analysis aims to estimate the outcomes of SNOM and immediate laparotomy in patients with GSWs by collecting the currently available evidence.

METHODS

The PubMed , EMBASE , and Cochrane Library databases were searched. A random-effects model was employed. A pooled proportion with 95% confidence intervals (CIs) was calculated. Heterogeneity was evaluated using Cochran's Q test and I2 statistics.

RESULTS

Overall, 53 studies involving 60 291 participants were included. The pooled proportions of SNOM and SNOM failure were 27.0% (95% CI=24.0-30.0%) and 10.0% (95% CI=7.0-13.0%), respectively. The pooled mortality after SNOM and SNOM failure were 0.0% (95% CI=0.0-1.0%) and 0.0% (95% CI=0.0-0.0%), respectively. The pooled proportions of immediate laparotomy and unnecessary immediate laparotomy were 73.0% (95% CI=70.0-76.0%) and 10.0% (95% CI=8.0-13.0%), respectively. The pooled mortality after immediate laparotomy and unnecessary immediate laparotomy was 10.0% (95% CI=8.0-13.0%) and 0.0% (95% CI=0.0-1.0%), respectively. Heterogeneity was statistically significant in nearly all meta-analyses.

CONCLUSION

Immediate laparotomy is still the mainstay approach for the management of abdominal GSWs. Approximately one-third of patients with abdominal GSWs undergo SNOM. SNOM failure is not frequent, and its related mortality is also rare.

Management of thoracoabdominal gunshot wounds - Experience from a major trauma centre in South Africa

INTRODUCTION

The management of thoracoabdominal (TA) gunshot wounds (GSW) remains challenging. This study reviewed our experience with treating such injuries over a decade.

MATERIALS AND METHODS

A retrospective study was conducted at a major trauma centre in South Africa over a ten-year period from December 2012 to January 2022.

RESULTS

Two hundred sixteen cases were included (male: 85 %, mean age: 33 years). Median RTS: 8 and median ISS: 17 (IQR: 10-19). The mean value of physiological parameters: Heart Rate (HR): 98/min, Systolic Blood Pressure (SBP): 119 mmHg, Temperature (T): 36.2 °C, pH: 7.35, Lactate 3.7 mmol/l. Ninety-nine (46 %) underwent a CT scan of the torso. One hundred fifty-four cases (69 %) were managed operatively: thoracotomy only [5/154 (3 %)], laparotomy only [143/154 (93 %)], and combined thoracotomy and laparotomy [6/154 (4 %)]. Those who had surgery following preoperative CT had a lower rate of dual cavity exploration (2 % vs 4 %, p = 0.51), although it did not reach statistical significance. The overall morbidity was 30 % (69). 82 % required intensive care (ICU) admission. The mean length of hospital stay was 14 days. The overall mortality was 13 % (28). Over the 10-year study period, there was a steady increase in the number of cases of TA GSWs managed at our institution. Over the study period, an increasing use of CT was noted, along with a steady reduction in the proportion of operations performed.

CONCLUSIONS

Thoraco-abdominal GSWs remain challenging to manage and continue to be associated with significant morbidity and mortality. The increased use of CT scans has reduced the degree of clinical confusion around which body cavity to prioritize, leading to an apparent decrease in dual cavity exploration, and has allowed for the increased use of minimalistic and non-operative approaches.

'Through and Through' History: The Management of Gunshot Wounds From the 14th Century to the Present

Gun violence killed over 46,000 Americans in 2021; almost 120,000 suffered gunshot wounds. This epidemic has attracted national attention and increasing concern from medical and surgical organizations, as evident in this special issue. 'Through and Through History' explores the surgical management of gunshot wounds from their earliest appearance in 14th-century Europe to the present. Interweaving the civilian and military experience, it details not only the evolution of care directly applied to patients but also the social, political, and scientific milieu that shaped decisions made and actions performed both in and out of the operating room. The article describes how surgeons have pushed the boundaries of medicine and science in each era, developing new therapies for their patients, a historical trend that persists today when such care has the potential to save tens of thousands of lives each year.

Traumatic hemorrhage and chain of survival

Trauma is the number one cause of death among Americans between the ages of 1 and 46 years, costing more than $670 billion a year. Following death related to central nervous system injury, hemorrhage accounts for the majority of remaining traumatic fatalities. Among those with severe trauma that reach the hospital alive, many may survive if the hemorrhage and traumatic injuries are diagnosed and adequately treated in a timely fashion. This article aims to review the recent advances in pathophysiology management following a traumatic hemorrhage as well as the role of diagnostic imaging in identifying the source of hemorrhage. The principles of damage control resuscitation and damage control surgery are also discussed. The chain of survival for severe hemorrhage begins with primary prevention; however, once trauma has occurred, prehospital interventions and hospital care with early injury recognition, resuscitation, definitive hemostasis, and achieving endpoints of resuscitation become paramount. An algorithm is proposed for achieving these goals in a timely fashion as the median time from onset of hemorrhagic shock and death is 2 h.

Accuracy of CT Scan for Detecting Hollow Viscus Injury in Penetrating Abdominal Trauma

BACKGROUND

In penetrating abdominal trauma, computed tomography (CT) is routinely performed to evaluate stable patients for selective non-operative management (SNOM). Triple-contrast CT (oral, rectal, and IV) has traditionally been used. However, due to its disadvantages, most trauma centres, including our unit at the Charlotte Maxeke Johannesburg Academic Hospital (CMJAH), now perform single-contrast intravenous-only CT scans. We performed a retrospective review to determine the accuracy of single-contrast CT scans for detecting hollow viscus injuries (HVI) in penetrating abdominal trauma.

METHODS

A retrospective review of all patients who presented to CMJAH with penetrating abdominal injuries was performed between 01 August 2017 and 31 August 2019 and were evaluated for SNOM with CT (IV contrast only). Patient records were reviewed to determine pertinent demographics, mechanism, and site of injury, as well as metabolic parameters. CT findings were compared to findings at laparotomy.

RESULTS

A total of 437 patients met the inclusion criteria. The majority were male (92.7%), with a mean age of 31.5 yrs (SD 8.7). Injuries were predominantly due to stab wounds (72,5%, n = 317). CT scan was negative in 342 patients, of which 314 completed SNOM successfully. A total of 93 patients proceeded to laparotomy. CT had a sensitivity of 95.1%, specificity of 44.2%, positive predictive value of 57.4%, and negative predictive value of 92%.

CONCLUSION

Single-contrast CT in penetrating abdominal trauma is a valuable investigative tool in identifying patients for SNOM. Features of HVI on single-contrast CT are not very specific and should be interpreted along with other clinical factors including wound trajectory and serial abdominal examinations. Other associated injuries such as diaphragmatic and solid organ injuries should be considered in the final management plan.

Treatment of a gunshot wound (birdshot) patient with traumatic shock in a hybrid emergency room

Background

Although the Hybrid Emergency Room System (HERS) is a relatively novel method for treating severe trauma patients, there have been few reported cases of gunshot wound patients treated in HERS. Here we report our treatment of a unique gunshot wound case, with shock, in a HERS setting.

Case presentation

A 72-year-old male was transferred to our hospital due to a gunshot wound (GSW). He presented with left chest injuries and vital signs consistent with shock. While resuscitating the patient, including massive blood transfusion and surgery to control the damage, a subsequent computed tomography in HERS revealed the internal distribution of the birdshot and damage to the abdominal organs. Lower lobectomy of the left lung and laparotomy for gastrointestinal repair were performed. After a planned repeat operation and reconstruction of the left chest wall, he was discharged uneventfully.

Conclusions

HERS during resuscitation was useful for helping clinicians not only to find the bullets' distribution and judge the severity of injury caused by the gunshot, but also to develop subsequent therapeutic strategies for rescuing the gunshot wound patient from a life-threatening situation.

Penetrating renal injuries: an observational study of non-operative management and the impact of opening Gerota's fascia

Background

Non-operative management has become increasingly popular in the treatment of renal trauma. While data are robust in blunt mechanisms, the role of non-operative management in penetrating trauma is less clear. Additionally, there is a paucity of data comparing gunshot and stab wounds.

Methods

A retrospective review of patients admitted to a high-volume level 1 trauma center (Groote Schuur Hospital, Cape Town) with penetrating abdominal trauma was performed. Patients with renal injuries were identified and compared based on mechanism [gunshot (GSW) vs. stab] and management strategy (operative vs. non-operative). Primary outcomes of interest were mortality and failure of non-operative management. Secondary outcomes of interest were nephrectomy rates, Clavien-Dindo complication rate, hospital length of stay, and overall morbidity rate.

Results

A total of 150 patients with renal injuries were identified (82 GSW, 68 stab). Overall, 55.2% of patients required emergent/urgent laparotomy. GSWs were more likely to cause grade V injury and concurrent intra-abdominal injuries (p > 0.05). The success rate of non-operative management was 91.6% (89.9% GSW, 92.8% stab, p = 0.64). The absence of hematuria on point of care testing demonstrated a negative predictive value of 98.4% (95% CI 96.8–99.2%). All but 1 patient who failed non-operative management had associated intra-abdominal injuries requiring surgical intervention. Opening of Gerota’s fascia resulted in nephrectomy in 55.6% of cases. There were no statistically significant risk factors for failure of non-operative management identified on univariate logistic regression.

Conclusions

NOM of penetrating renal injuries can be safely and effectively instituted in both gunshot and stab wounds with a very low number of patients progressing to laparotomy. Most patients fail NOM for associated injuries. During laparotomy, the opening of Gerota’s fascia may lead to increased risk of nephrectomy. Ongoing study with larger populations is required to develop effective predictive models of patients who will fail NOM.

Race and insurance status outcome disparities following splenectomy in trauma patients are reduced in larger hospitals. A cross-sectional study

Background

Splenectomy, still a commonly performed treatment for splenic injury in trauma patients, has been shown to have a high rate of complications. The purpose of this study was to identify predictors, including race and insurance status, associated with adverse outcomes post-splenectomy in trauma patients. We discuss possible explanations and methods for reducing these disparities.

Methods

The American College of Surgeons – Trauma Quality Improvement Program (ACS-TQIP) participant user database was queried from 2010 to 2015 and patients who underwent total splenectomy were identified. All mechanisms of injury, including both blunt and penetrating trauma, were included. Patients with advance directives limiting care or aged under 18 were excluded. Propensity score matching was used to control for age, preexisting medical conditions, and the severity of the traumatic injury. A chi-squared test was used to find significant associations between available predictors and outcomes for this cross-sectional study.

Results

The post-splenectomy mortality rate was 9.2% (n = 1047), 8.0% (n = 918) of patients had three or more complications, and 20.3% (n = 2315) had major complications. A primary race of white (OR 0.7, 95% Confidence Interval (CI) 0.6–0.9, p < 0.01) and private insurance (OR 0.5, 95%CI 0.4–0.6, p < 0.01) were associated with lower risks of mortality A primary race of neither Black nor white (OR 1.3, 95%CI 1.03–1.7, p = 0.03) and a lack of health insurance (“self-pay”) (OR 1.6, 95%CI 1.3–1.9, p < 0.01) were both correlated with mortality. When limited to hospitals of 600+ beds, there were no associations between race and mortality.

Conclusion

The post-splenectomy mortality rate after trauma remains high. In U.S. trauma centers, a primary race of Black and payment status of “self-pay” are associated with adverse outcomes after splenectomy following a traumatic injury. These disparities are reduced when limiting analysis to larger hospitals. Efforts to reduce disparities in outcomes among trauma patients requiring a splenectomy should focus on improving resource availability and quality in smaller hospitals.

•

The post-splenectomy mortality rate in trauma patients remains high.

•

Mortality is less frequent in white patients, and more frequent in uninsured patients.

•

Black patients were more likely to experience major complications following splenectomy.

•

In hospitals with greater than 600 beds, there were no associations between race and mortality following splenectomy.

WSES guidelines on blunt and penetrating bowel injury: diagnosis, investigations, and treatment

The aim of this paper was to review the recent literature to create recommendations for the day-to-day diagnosis and surgical management of small bowel and colon injuries. Where knowledge gaps were identified, expert consensus was pursued during the 8th International Congress of the World Society of Emergency Surgery Annual (September 2021, Edinburgh). This process also aimed to guide future research.

Comparative Study between Operative and Conservative Management of Penetrating Anterior Abdominal Stab Injuries

Background: Presently, non-operative management of penetrating abdominal stab injuries has been standardized in several trauma centers. This strategy has appromising outcome conserving decreasing morbidity. Aim of the work: This study aimed to assess the safety and feasibility of SNOM of patients having penetrating abdominal stab injuries not indicating emergent laparotomy and  to identify a protocol for selection of patient candidates for non-operative management in a tertiary care hospital in Egypt. Patients & Methods: This is a prospective study that involved patients who presented to the casualty department of Kasr Elainy teaching Hospital, in the period from August 2018 to August 2020, for management of a penetrating abdominal Stab injuries. Fully conscious, haemodynimacally stable patients were included. Eligible patients were allocated to either SNOM group or immediate operative management (IOM) group. Results: SNOM group included64 patients and IOM group included 40 patients. The age of the patients ranged from 16 to 49 years with a mean of 33±6.8 years, and the majority were males (99%). SNOM failed in 4/69 patients (5.7%) who required delayed laparotomy for peritonitis (2 cases) and HB drop and haemodynamic instability (2 cases). In IOM group, only 3 cases had therapeutic laparotomies (7.3%). The remaining cases had unnecessary laparotomies (92.7%). Statistically significant higher LOS was seen in SNOM group (p<0.05). However, less unnecessary laparotomies and lower incidences of complications were noted (p<0.01). Conclusion: vital signs together with abdominal examination are the most important clinical criteria in decision making in penetrating abdominal stab injury patients  When surgery is not absolutely indicated, SNOM is a safe and feasible approach in management of penetrating abdominal stab injury by following proper management algorithm and selection criteria.

Trends in the Management of Abdominal Gunshot Wounds Over the Last Decade: A South African Experience

BACKGROUND

This study aimed to review our decade-long experience with the management of abdominal gunshot wounds (GSWs), to document trends in our approach and to develop an evidence base for our contemporary management algorithms in a major trauma in South Africa.

MATERIALS AND METHODS

This was a retrospective study that included all adult patients with abdominal GSWs between January 2013 and October 2020 managed at a major trauma centre in South Africa.

RESULT

Five hundred and ninety-six cases were included (87% male, mean age: 32 years). The median Injury Severity Score (ISS) was 12. 52% (309/596) of cases had indications of immediate laparotomy and proceeded directly to the operating room without any CT imaging. Of this cohort, the laparotomy was positive in 292 and in the remainder (5%) was negative. Of the remaining 287 cases, 209 underwent a CT scan (35%). 78 were managed without any CT imaging. Of the 78 who did not undergo CT scan, all were managed without any operation and discharged home well. Of the 209 who underwent CT scan, 99 were observed and only one case in this group subsequently required a laparotomy. The remaining 110 cases underwent a laparotomy, which was negative in 7. There were correlations with increasing use of CT, as well as a decrease in those proceeding directly to laparotomy. The overall morbidity rate was 8% (47/596). 32% (190/596) require intensive care unit (ICU) admission. The overall mortality rate was 8% (67/596).

CONCLUSIONS

The management of abdominal GSWs has continued to evolve. There is now a well-defined role for selective non-operative management in this group of patients and relies on accurate CT assessment. CT scan is now an important component in the management of abdominal GSW even in our resource-constrained environment.

A Prospective Audit of 805 Consecutive Patients With Penetrating Abdominal Trauma: Evolving Beyond Injury Mechanism Dictating Management

BACKGROUND

Global trends of penetrating abdominal trauma (PAT) have seen a shift toward a selectively conservative management strategy. However, its widespread adoption for gunshot injuries has been sluggish. The purpose of this study is to compare the injury mechanisms of gunshot (GSW) and stab wounds (SW) to the abdomen in presentation, management, and outcomes.

METHODS

Prospective cohort study, set in Cape Town, South Africa, over 2 years. All patients presenting to the center with PAT during this time were included. Presentation, management, and outcomes were compared by injury mechanism, with a focus on the operative strategy (operative vs nonoperative).

RESULTS

During the study period, 805 patients (SW 37.6%; GSW 62.4%) with PAT were managed. Immediate laparotomies were performed in 119 (39.3%) SW and 355 (70.7%) GSW, with a therapeutic laparotomy rate of 85.7% and 91.8% for SW and GSW, respectively. Nonoperative management (NOM) was implemented in 184 SW (60.7%) and 147 GSW (29.3%) (P < 0.001), with a 92.9% and 92.5% success rate for SW and GSW, respectively. The therapeutic laparotomy rate for the delayed laparotomies (DOM) was 69.2% for SW, and 90.9% for GSW. The accuracy of clinical assessment (with adjuncts) in determining the need for laparotomy was: GSW-92% and SW-91%. Univariate analysis revealed the mechanism not to be associated with DOM. The overall mortality rate was 7.2%, and nonfatal morbidities 22.2%.

CONCLUSION

Although GSW is a more morbid and often fatal injury, the general principles of selective conservatism hold true for both GSW and SW, equally.

Expectant management in delayed presentation of war casualties with penetrating abdominal trauma

INTRODUCTION

While the management of acute civilian abdominal injuries is well established, The literature regarding the management of battle-related abdominal injuries presented in a delayed fashion is scarce. The objective of this study was to investigate the safety of non-operative management approach in delayed evacuation of battle-related abdominal injuries.

METHODS

Clinical records of thirty-seven hemodynamically normal patients with battle related injuries and Computed Tomography (CT) findings of penetrating abdominal trauma were retrospectively studied.

RESULTS

All 37 patients suffered penetrating abdominal injuries during the civil war in Syria. In this complex scenario, the casualties presented after a minimum 12-hour delay to our hospital. All patients had abnormal abdominal CT scans with no clinical peritoneal signs. Twenty-one [of the 37] patients exhibited 29 hard signs on CT scan. Of these, 17 patients were treated non-operatively and 4 underwent exploratory laparotomy (of which 2 were non-therapeutic). Sixteen patients exhibited a total of 75 soft signs on CT scan; 15 were treated non-operatively and one underwent non-therapeutic laparotomy. No complications were recorded in either the operative or non-operative groups. In total, 32 patients (86%) were treated non-operatively. Five patients (14%) underwent exploratory laparotomy (3 of which were non-therapeutic). Length of stay was dependent on the unique requirements of each individual patient as determined by the state department for returning across the border.

CONCLUSION

We propose that in battle related casualties, acute survivable penetrating abdominal trauma may be safely treated non-operatively in selected patients who are hemodynamically normal and in whom there is an absence of abdominal pain or tenderness on repeated clinical assessment.

Selective non-operative management of penetrating abdominal injuries at Northern European trauma centers: the NordiPen Study

PURPOSE

A selective nonoperative management (SNOM) of penetrating abdominal injuries (PAI) is a standard of care in numerous established trauma centers. However, available evidence supporting SNOM of PAI in European settings remains scarce. Thus, we performed a multi-center study at selected Northern European trauma centers to investigate the management and outcomes of PAI. We hypothesized that despite a low number of penetrating injuries in included trauma centers, SNOM is successfully utilized with outcomes comparable with trauma centers with a high number of PAI.

METHODS

All adult patients admitted to participating trauma centers in the Northern European region with PAI between 1/2015 and 12/2016 were retrospectively reviewed. Primary outcomes were mortality and success rate of SNOM.

RESULTS

Overall, 119 patients were included. Median age was 38 (28-47) years. SNOM was initiated in 55 patients (46.0%) with 94.5% success rate. Three patients (5.5%) failed SNOM and had a delayed laparotomy with one gastric injury, one small bowel injury and one patient with a bleeding from mesentery. Overall mortality of the cohort was 5.0%. However, all patients in the SNOM group survived. Higher median ISS, median Abbreviated Injury Scale score of the abdomen, rate of combined anterior and posterior wounds, rate of in-hospital complications and longer hospital length of stay were observed in the immediate laparotomy group compared to the SNOM group.

CONCLUSIONS

SNOM of PAI is a safe practice even in regions with a low prevalence of penetrating injuries. The outcomes in our study are comparable with results from trauma centers treating larger numbers of patients with PAI.

Conservative Management of Gunshot Wound to Anterior Abdomen in a Resource-Poor Setting in the Caribbean

Previously, the management of gunshot wounds (GSWs) to the anterior abdomen required exploratory laparotomy; however, this was associated with a considerable number of non-therapeutic surgeries. The use of non-operative management (NOM) of GSW to the abdomen is controversial, with many surgeons sceptical to accept this into their practice. The NOM of GSW to the abdomen employed in a selected group of patients has been shown to be safe and acceptable. Penetrating GSW to the thoraco-abdomen, back and lateral abdomen has been the most successful compared to the anterior penetrating wound. Most of the anterior GSWs to the abdomen are associated with viscus injury and require exploratory laparotomy. We report the case of a 58-year-old male who presented with a single GSW to the epigastrium with a contrast computed tomography scan demonstrating grade 3 liver lacerations, contusion to the right adrenal gland, with moderate free fluids in the retroperitoneum and the pelvis. The patient was haemodynamically stable and managed successfully with NOM. It is one of the safe routes of anterior penetration of GSW to the abdomen and treated with conservative management.

A special acute care surgery model for dealing with dilemmas involved in emergency department in China

There was a fast growth in the number and the formation of emergency department (ED) visits in China during the twenty-first century. As a result, engaging special medical model will be essential to decompressing the ED visits. To do this, it will be important to understand which specific aspects to focus interventions on for the greatest impact. To characterize the emergency surgery patients who were seen and discharged from ED. Retrospective cohort study of hospitalized emergency surgery patients currently under the care from specialists presenting to an urban, university affiliated hospital between 01 January 2018 and 1 January 2019. This study will highlight some of the controversies and challenges and key lessons learned. During the study period there were 231,229 ED visits; 4100 of these patients were admitted for Acute care surgery (ACS) service. Multivariate analysis identified age ≧ 65 (p = 0.023; odds ratio, OR = 2.66), ACS model (p = 0.000, OR = 0.18), ICU stay (p = 0.000, OR = 118.73) as factors associated with in-hospital mortality. There was a increase in length of stay between young and elderly postoperative patients when stratifying patients by age (11.67 ± 9.48 vs 13.95 ± 9.11 p < 0.05). ED overcrowding is not just an ED problem. ED overcrowding is a systems problem requiring a systematic facility-wide multidisciplinary response. Continuous and high-quality surveillance data across China are needed to estimate the acute care surgery model which used to deal with ED overcrowding.

Resuscitative endovascular balloon of the aorta is feasible in penetrating chest trauma with major hemorrhage: Proposal of a new institutional deployment algorithm

BACKGROUND

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an emerging option for hemorrhage control, but its use is limited in scenarios such as penetrating chest trauma. The aim of this study was to describe the use of REBOA as a resuscitative adjunct in these cases with major hemorrhage and to propose a new clinical management algorithm.

METHODS

This was a prospective, observational study conducted at a single Level I trauma center in Colombia. We included all patients older than 14 years with severe trauma who underwent REBOA from January 2015 to December 2019. Patients received REBOA if they were in hemorrhagic shock and were unresponsive to resuscitation.

RESULTS

A total of 56 patients underwent REBOA placement of which 37 had penetrating trauma and 23 had chest trauma. All patients were hemodynamically unstable upon arrival to the emergency department, with a median systolic blood pressure of 69 mm Hg (interquartile range [IQR], 57-90 mm Hg) and median Injury Severity Score was 25 (IQR, 25-41). All REBOAs were deployed and inflated in zone 1, median inflation time was 40 minutes (IQR, 26-55 minutes), and no adverse neurologic outcomes were observed. Fifteen patients had REBOA and a median sternotomy. Eleven patients had concomitant abdominal wounds. Overall mortality was 28.6%, and there was no significant difference between penetrating versus blunt trauma patients (21.6% vs. 42.1%, p = 0.11). The survival rate of thoracic injured patients was similar to the predicted survival (65.2% vs. 63.3%).

CONCLUSION

Resuscitative endovascular balloon occlusion of the aorta can be used safely in penetrating chest trauma, and the implementation of a REBOA management algorithm is feasible with a well-trained multidisciplinary team.

Effective management of a firearm injury with multiple intestinal perforation in a COVID 19 positive patient: A rare case report

INTRODUCTION

A challenging situation lies in front of every surgeon to perform emergency surgeries in a pandemic scenario. Gunshot injuries in a COVID-19 affected individual increases the chances of post-operative morbidity and mortality. Such cases require multidisciplinary approach with an advanced COVID care for the satisfactory outcome.

CASE PRESENTATION

We present a case of 30-year-old male with an alleged history of an accidental fire arm injury. His rapid antigen for COVID was positive. Contrast enhanced computed tomogram (CECT) abdomen was suggestive of multiple bowel injuries. Emergency exploratory laparotomy confirmed multiple bowel perforations with no associated solid organ injury. Perforated sites were sealed by primary repair and loop ileostomy was performed. Patient was discharged on post-operative Day 17 with satisfactory clinical improvement.

DISCUSSION

Deleterious effects of COVID-19 has questioned the reliance on health care system across the globe. Pulmonary complications affect the post-operative course in patients undergoing surgery. However not every patient with peri operatively detected COVID-19 will have complicated post-operative course. Managing such patients with perioperative COVID-19 is an uphill task. Hemodynamic instability and clinical signs of peritonitis mandates the operative management. Multidisciplinary approach with advanced post-operative COVID care is required for satisfactory outcome.

CONCLUSION

Management of patients undergoing emergency procedure with peri-operative COVID 19 is challenging for the attending surgeon. Consider all surgical emergencies as COVID positive unless proved otherwise. Multidisciplinary approach for management of COVID-19 infection along with good post-operative care is required.

Penetrating abdominal trauma in the era of selective conservatism: a prospective cohort study in a level 1 trauma center

BACKGROUND

Global trend has seen management shift towards selective conservatism in penetrating abdominal trauma (PAT). The purpose of this study is to compare the presentation; management; and outcomes of patients with PAT managed operatively versus non-operatively.

METHODS

Prospective cohort study of all patients Ùpresenting with PAT to Groote Schuur Hospital, Cape Town from 01 May 2015 to 30 April 2017. Presentation; management; and outcomes of patients were compared. Univariate predictors of delayed operative management (DOM) were explored.

RESULTS

Over the 2-year study period, 805 patients with PAT were managed. There were 502 (62.4%); and 303 (37.6%) patients with gunshot (GSW) and stab wounds (SW), respectively. The majority were young men (94.7%), with a mean age of 28.3 years (95% CI 27.7-28.9) and median ISS of 13 (IQR 9-22). Successful non-operative management was achieved in 304 (37.7%) patients, and 501 (62.5%) were managed operatively. Of the operative cases, 477 (59.3%) underwent immediate laparotomy and 24 (3.0%) DOM. On univariate analysis, number; location; and mechanism of injuries were not associated with DOM. Rates of therapeutic laparotomy were achieved in 90.3% in the immediate, and 80.3% in the DOM cohorts. The mortality rate was 1.3, 11.3 and 0% in the in the NOM, immediate laparotomy and DOM subgroups, respectively. The rate of complications was no different in the immediate and DOM cohorts (p > 0.05).

CONCLUSION

Patients with PAT in the absence of haemodynamic instability; peritonism; organ evisceration; positive radiological findings, or an unreliable clinical examination, can be managed expectantly without increased morbidity or mortality.

The gap in operative exposure in trauma surgery: quantifying the benefits of an international rotation

Background

International rotations with hands-on experience are commonly cited as a potential supplement to the current experience of surgical trainees in trauma; however, quantification of this experience remains unclear.

Methods

A link to an online survey was distributed by electronic mail to physicians who rotated for any period of time at the Trauma Unit of the Groote-Shuur Hospital of the University of Cape Town from January 1, 2006, to December 2016.

Results

Of 160 participants, 75 (47%) completed the survey. A high proportion (45%) had performed less than 25 trauma-related surgical procedures during their previous training. Most (56%) performed ≥ 10 trauma laparotomies and sternotomies/thoracotomies during their rotation, whereas 43% performed ≥ 5 vascular procedures. The level of perceived confidence in managing trauma patients increased significantly from a median of 3/10 to 7/10 (P < .05).

Conclusion

Rotations at large-volume trauma centers abroad offer the opportunity for a hands-on operative experience and may enhance the confidence of surgical trainees. Further standardization of these opportunities may result in a larger-scale participation of graduate residents and fellows.

•

This is a survey of physicians who participated in an international rotation at the Groote Schuur Hospital of the University of Cape Town.

•

With this survey, we found that most participants performed in excess of 10 trauma laparotomies and thoracotomies/sternotomies.

•

A large proportion performed 5 or more peripheral vascular procedures.

•

These findings are combined with a significantly increased confidence in managing trauma patients.

•

This report may serve in the planning of sponsored international rotations to increase the operative exposure in trauma surgery.

Selective conservative treatment for anterior abdominal gunshot: a literature narrative review

The nonoperative treatment of anterior abdominal gunshot wounds remains controversial. This article presents a narrative review of the literature after the selection of studies in electronic databases (PubMed, Cochrane Library and Lilacs), with the intention of evaluating the clinical and diagnostic tools that should be part of conservative selective approach of these lesions. It was observed that a nonoperative selective treatment can be effectively and safely used, when performed by a trained interdisciplinary team, working in adequate trauma centers. The selective nonoperative treatment is associated with a decrease in negative and nontherapeutic laparotomies, reducing the incidence of complications. It also contributes to the reduction of hospital costs.

Selective non-operative management for penetrating abdominal injury in a Dutch trauma centre

INTRODUCTION

Selective non-operative management (SNOM) for penetrating abdominal injury (PAI) is accepted in trauma centres in South Africa and the US. Owing to the low incidence of gunshot wounds (GSWs) in Western Europe, few are inclined to practise SNOM for such injuries although it is considered for stab wounds (SWs). This study evaluated the outcome of patients admitted to a Dutch level 1 trauma centre with PAI.

METHODS

A retrospective study was undertaken of all PAI patients treated over 15 years. In order to prevent bias, patients admitted six months prior to and six months following implementation of a treatment algorithm were excluded. Data concerning type of injury, injury severity score and treatment were compared.

RESULTS

A total of 393 patients were included in the study: 278 (71%) with SWs and 115 (29%) with GSWs. Of the 178 SW patients in the SNOM group, 111 were treated before and 59 after introduction of the protocol. The SNOM success rates were 90% and 88% respectively (p=0.794). There were 43 patients with GSWs in the SNOM cohort. Of these, 32 were treated before and 11 after implementation of the algorithm, with respective success rates of 94% and 100% (p=0.304).The protocol did not bring about any significant change in the rate of non-therapeutic laparotomies for SWs or GSWs. However, the rate of admission for observation for SWs increased from 83% to 100% (p<0.001). There was a decrease in ultrasonography for SWs (from 84% to 32%, p<0.001) as well as for GSWs (from 87% to 43%, p<0.001). X-ray was also used less for GSWs after the protocol was introduced (44% vs 11%, p=0.001).

CONCLUSIONS

SNOM for PAI resulting from either SWs or GSWs can be safely practised in Western European trauma centres. Results are comparable with those in trauma centres that treat high volumes of PAI cases.

Liver trauma: WSES 2020 guidelines

Liver injuries represent one of the most frequent life-threatening injuries in trauma patients. In determining the optimal management strategy, the anatomic injury, the hemodynamic status, and the associated injuries should be taken into consideration. Liver trauma approach may require non-operative or operative management with the intent to restore the homeostasis and the normal physiology. The management of liver trauma should be multidisciplinary including trauma surgeons, interventional radiologists, and emergency and ICU physicians. The aim of this paper is to present the World Society of Emergency Surgery (WSES) liver trauma management guidelines.

Kidney and uro-trauma: WSES-AAST guidelines

Renal and urogenital injuries occur in approximately 10-20% of abdominal trauma in adults and children. Optimal management should take into consideration the anatomic injury, the hemodynamic status, and the associated injuries. The management of urogenital trauma aims to restore homeostasis and normal physiology especially in pediatric patients where non-operative management is considered the gold standard. As with all traumatic conditions, the management of urogenital trauma should be multidisciplinary including urologists, interventional radiologists, and trauma surgeons, as well as emergency and ICU physicians. The aim of this paper is to present the World Society of Emergency Surgery (WSES) and the American Association for the Surgery of Trauma (AAST) kidney and urogenital trauma management guidelines.

Trends in the Nature and Management of Serious Abdominal Trauma

BACKGROUND

There have been recommendations for increased non-operative management (NOM) of abdominal trauma in adults. To assess the impact of this trend and changes in the epidemiology of trauma, we examined the management of serious abdominal injuries and mortality, in Victorian major trauma patients 16 years or older, between 2007 and 2016.

METHODS

Using data from the population-based Victorian Trauma Registry, characteristics of patients who underwent laparotomy, embolisation, laparotomy and embolisation, or NOM, were compared with the Chi-square test. Poisson regression was used to determine whether the incidence of serious abdominal injury changed over time. Temporal trends in the management of abdominal injury and in-hospital mortality were analysed using, respectively, the Chi-square test for trend, and multivariable logistic regression.

RESULTS

Of 2385 patients with serious abdominal injuries, 69% (n = 1649) had an intervention; predominantly a laparotomy (n = 1166). The proportion undergoing laparotomy decreased from 60% in 2007 to 44% in 2016 (p < 0.001), whilst embolisation increased from 6 to 20% (p < 0.001). Population-adjusted incidence of abdominal injury increased 1.6% per year (IRR 1.016, 95% CI 1.002-1.031; p < 0.024), predominantly in people aged 65 years and over (4.6% per year). Adjusted odds of in-hospital mortality declined 6.0% per year (adjusted odds ratio 0.94; 95% CI 0.89, 1.00; p = 0.04).

CONCLUSIONS

Whilst the incidence of major abdominal trauma increased during the study period, there was a reduction in the proportion of patients managed with laparotomy and reduction in the adjusted odds of in-hospital mortality. Older patients, for whom management is influenced by the complex interplay of frailty and co-morbidities, had lower laparotomy rates.

Selective non-operative management for penetrating splenic trauma: a systematic review

Introduction

The treatment of abdominal solid organ injuries has shifted towards non-operative management (NOM). However, the feasibility of NOM for penetrating splenic trauma is unclear and outcome is believed to be worse than NOM for penetrating liver and kidney injuries. Hence, the aim of the current systematic review was to evaluate the feasibility of selective NOM in penetrating splenic injury.

Methods

A review of literature was performed using Pubmed, Embase and Cochrane databases. Studies on adult patients treated by NOM for splenic injuries were included and outcome was documented and compared.

Results

Five articles from exclusively level-1 and level-2-traumacenters were selected and a total of 608 cases of penetrating splenic injury were included. Nonoperative management was applied in 123 patients (20.4%, range 17–33%). An overall failure rate of NOM of 18% was calculated. Mortality was not seen in patients selected for nonoperative management. Contra-indicatons for NOM included hemodynamic instability, absence of abdominal CT-scanning to rule out concurrent injuries and peritonitis.

Conclusions

This review demonstrates that non-operative management for penetrating splenic trauma in highly selected patients has been utilized in several well-equipped and experienced trauma centers. NOM of penetrating splenic injury in selected patients is not associated with increased morbidity nor mortality. Data on the less well-equipped and experienced trauma centers are not available. More prospective studies are required to further define exact selection criteria for non-operative management in splenic trauma.

Contemporary management of high-grade renal trauma: Results from the American Association for the Surgery of Trauma Genitourinary Trauma study

BACKGROUND

The rarity of renal trauma limits its study and the strength of evidence-based guidelines. Although management of renal injuries has shifted toward a nonoperative approach, nephrectomy remains the most common intervention for high-grade renal trauma (HGRT). We aimed to describe the contemporary management of HGRT in the United States and also evaluate clinical factors associated with nephrectomy after HGRT.

METHODS

From 2014 to 2017, data on HGRT (American Association for the Surgery of Trauma grades III-V) were collected from 14 participating Level-1 trauma centers. Data were gathered on demographics, injury characteristics, management, and short-term outcomes. Management was classified into three groups-expectant, conservative/minimally invasive, and open operative. Descriptive statistics were used to report management of renal trauma. Univariate and multivariate logistic mixed effect models with clustering by facility were used to look at associations between proposed risk factors and nephrectomy.

RESULTS

A total of 431 adult HGRT were recorded; 79% were male, and mechanism of injury was blunt in 71%. Injuries were graded as III, IV, and V in 236 (55%), 142 (33%), and 53 (12%), respectively. Laparotomy was performed in 169 (39%) patients. Overall, 300 (70%) patients were managed expectantly and 47 (11%) underwent conservative/minimally invasive management. Eighty-four (19%) underwent renal-related open operative management with 55 (67%) of them undergoing nephrectomy. Nephrectomy rates were 15% and 62% for grades IV and V, respectively. Penetrating injuries had significantly higher American Association for the Surgery of Trauma grades and higher rates of nephrectomy. In multivariable analysis, only renal injury grade and penetrating mechanism of injury were significantly associated with undergoing nephrectomy.

CONCLUSION

Expectant and conservative management is currently utilized in 80% of HGRT; however, the rate of nephrectomy remains high. Clinical factors, such as surrogates of hemodynamic instability and metabolic acidosis, are associated with nephrectomy for HGRT; however, higher renal injury grade and penetrating trauma remain the strongest associations.

Outcomes of selective nonoperative management of civilian abdominal gunshot wounds: a systematic review and meta-analysis

Background

Although mandatory laparotomy has been standard of care for patients with abdominal gunshot wounds (GSWs) for decades, this approach is associated with non-therapeutic operations, morbidity, and long hospital stays. This systematic review and meta-analysis sought to summarize outcomes of selective nonoperative management (SNOM) of civilian abdominal GSWs.

Methods

We searched electronic databases (March 1966-April 1, 2017) and reference lists of articles included in the systematic review for studies reporting outcomes of SNOM of civilian abdominal GSWs. We meta-analyzed the associated risks of SNOM-related failure (defined as laparotomy during hospital admission), mortality, and morbidity across included studies using DerSimonian and Laird random-effects models. Between-study heterogeneity was assessed by calculating I2 statistics and conducting tests of homogeneity.

Results

Of 7155 citations identified, we included 41 studies [n = 22,847 patients with abdominal GSWs, of whom 6777 (29.7%) underwent SNOM]. The pooled risk of failure of SNOM in hemodynamically stable patients without a reduced level of consciousness or signs of peritonitis was 7.0% [95% confidence interval (CI) = 3.9-10.1%; I2 = 92.6%, homogeneity p < 0.001] while the pooled mortality associated with use of SNOM in this patient population was 0.4% (95% CI = 0.2-0.6%; I2 = 0%, homogeneity p > 0.99). In patients who failed SNOM, the pooled estimate of the risk of therapeutic laparotomy was 68.0% (95% CI = 58.3-77.7%; I2 = 91.5%; homogeneity p < 0.001). Risks of failure of SNOM were lowest in studies that evaluated patients with right thoracoabdomen (3.4%; 95% CI = 0-7.0%; I2 = 0%; homogeneity p = 0.45), flank (7.0%; 95% CI = 3.9-10.1%), and back (3.1%; 95% CI = 0-6.5%) GSWs and highest in those that evaluated patients with anterior abdomen (13.2%; 95% CI = 6.3-20.1%) GSWs. In patients who underwent mandatory abdominopelvic computed tomography (CT), the pooled risk of failure was 4.1% versus 8.3% in those who underwent selective CT (p = 0.08). The overall sample-size-weighted mean hospital length of stay among patients who underwent SNOM was 6 days versus 10 days if they failed SNOM or developed an in-hospital complication.

Conclusions

SNOM of abdominal GSWs is safe when conducted in hemodynamically stable patients without a reduced level of consciousness or signs of peritonitis. Failure of SNOM may be lower in patients with GSWs to the back, flank, or right thoracoabdomen and be decreased by mandatory use of abdominopelvic CT scans.

Contemporary management of renal trauma in Canada: A 10-year experience at a level 1 trauma centre

INTRODUCTION

Contemporary Canadian renal trauma data is lacking. Our objective is to describe 10-year outcomes of renal trauma at a Canadian level 1 trauma centre using a conservative approach.

METHODS

The Alberta Trauma Registry at the University of Alberta was used to identify renal trauma patients from October 2004 to December 2014. Hospital records and imaging were reviewed to identify clinic-radiographical factors, including patient age, gender, Injury Severity Score (ISS), American Association of the Surgery for Trauma (AAST) grade, computerized tomography (CT) findings, urological interventions, length of stay, transfusion and death rates. Descriptive statistics, Chi-square, and t-tests were used when appropriate.

RESULTS

A total of 368 renal trauma patients were identified. Mechanism of injury was blunt trauma in 89.1% of cases, mean age was 36.2 years, and mean ISS was 30.8 (±13.6). AAST grade distribution was 16.6% (Grade 1), 22.8% (Grade 2), 36.4% (Grade 3), 20.9% (Grade 4), and 3.3% (Grade 5). Overall, 9.5% (35) of patients required urological intervention for a total of 40 treatments, including ureteral stenting (3.0%), angioembolization (3.3%), percutaneous drainage (0.3%), or open intervention including nephrectomy (2.4%) and renorrhaphy (0.5%). No Grade 1 or 2 injuries required intervention, while 1.5%, 31.2%, and 75.0% of Grade 3, 4, and 5 injuries did, respectively. The overall renal salvage rate was 97.6%, which did not differ by mechanism of injury (p=0.25). Patients with penetrating trauma were more likely to require urological intervention (20.0% vs. 8.2%; p=0.04). Of the high-grade (III-V) renal injuries identified, 15.7% (35/223) required urological intervention, 4.9% (11) required open surgical intervention, and only 4.0% (9) of patients with high-grade renal injury required nephrectomy.

CONCLUSIONS

The trend towards conservative treatment of renal trauma in Canada appears well-supported even in a severely injured patient population, as over 90% of patients avoid urological intervention and only 3% require operative intervention resulting in renal salvage rates of 97.6%.

Diagnostic laparoscopy or selective non-operative management for stable patients with penetrating abdominal trauma: What to choose?

Background

Selective non-operative management (NOM) and diagnostic laparoscopy (DL) are well-accepted approaches in the management of stable patients with penetrating abdominal trauma (PAT). The aim of this pilot study was to investigate the advantages and disadvantages of early DL in stable asymptomatic or minimally symptomatic patients with PAT as opposed to NOM, a standard of care in this scenario. The secondary aim was to suggest possible indications for DL.

Methods

Patients managed with DL or NOM over a 12-month period were included in this study. The age, gender, mechanism and location of injuries, trauma scores, haemodynamic and metabolic parameters, intraoperative findings and length of hospital stay (LOS) were recorded and correlated with outcomes.

Results

Thirty-six patients were in the NOM group and 35 in the DL group. Stab wounds were more common. The most common location of injury was the anterior abdominal wall in the NOM group and the lower chest in the DL group. Computed tomography (CT) scan was performed more often in the NOM group (75% vs. 17.1%). The injury severity score (ISS), New ISS and PAT Index were higher in the DL group. Nearly 23 (66%) patients in the DL group had a penetration of the peritoneum, but no significant abdominal injuries. LOS in the NOM group was 2 days versus 3.1 days in the DL group. There were no missed injuries, complications or mortality.

Conclusion

NOM is a preferred modality for minimally symptomatic stable patients. However, there is a risk of missed injuries and delayed treatment. DL accurately visualizes injuries, decreases unnecessary CT scans and avoids nontherapeutic laparotomies.

Non-operative management of abdominal gunshot injuries: Is it safe in all cases?

Objective

In line with advances in diagnostic methods and expectation of a decrease in the number of negative laparotomies, selective non-operative management of abdominal gunshot wounds has been increasingly used over the last three decades. We aim to detect the possibility of treatment without surgery and present our experience in selected cases referred from Syria to a hospital at the Turkish-Syrian border.

Material and Methods

Between February 2012 and June 2014, patients admitted with abdominal gunshot wounds were analyzed. Computed tomography was performed for all patients on admission. Patients who were hemodynamically stable and did not have symptoms of peritonitis at the time of presentation were included in the study. The primary outcome parameters were mortality and morbidity. Successful selective non-operative management (Group 1) and unsuccessful selective non-operative management (Group 2) groups were compared in terms of complications, blood transfusion, injury site, injury severity score (ISS), and hospital stay.

Results

Of 158 truncal injury patients, 18 were considered feasible for selective non-operative management. Of these, 14 (78%) patients were treated without surgery. Other Four patients were operated upon progressively increasing abdominal pain and tenderness during follow-up. On diagnostic exploration, all of these cases had intestinal perforations. No mortality was observed in selective non-operative management. There was no statistically significant difference between Group 1 and Group 2, in terms of length of hospital stay (96 and 127 h, respectively). Also, there was no difference between groups in terms of blood transfusion necessity, injury site, complication rate, and injury severity score (p>0.05).

Conclusion

Decision making on patient selection for selective non-operative management is critical to ensure favorable outcomes. It is not possible to predict the success of selective non-operative management in advance. Cautious clinical examination and close monitoring of these patients is vital; however, emergency laparotomy should be performed in case of change in vital signs and positive symptoms concerning peritonitis.

The role of computerized tomography in penetrating abdominal trauma

OBJECTIVE

to evaluate the role of abdominal computed tomography in the management of penetrating abdominal trauma.

METHODS

we conducted a historical cohort study of patients treated for penetrating trauma in the anterior abdomen, dorsum or thoracoabdominal transition, that were submitted to a computed tomography carried out on admission. We evaluated the location of the wound and the presence of tomographic findings, and the management of these patients as for nonoperative treatment or laparotomy. We calculated the sensitivity and specificity of computed tomography according to the evolution of the nonoperative treatment or the surgical findings.

RESULTS

we selected 61 patients, 31 with trauma to the anterior abdomen and 30 to the dorsum or thoracoabdominal transition. The mortality rate was 6.5% (n=4), all in the late postoperative period. Eleven patients with trauma to the anterior abdomen were submitted to nonoperative treatment, and 20, to laparotomy. Of the 30 patients with trauma to the dorsum or thoracoabdominal transition, 23 underwent nonoperative treatment and seven, laparotomy. There were three nonoperative treatment failures. In penetrating trauma of the anterior abdomen, the sensitivity of computed tomography was 94.1% and the negative predictive value was 93.3%. In dorsal or thoracoabdominal transition lesions, the sensitivity was 90% and the negative predictive value was 95.5%. In both groups, the specificity and the positive predictive value were 100%.

CONCLUSION

the accuracy of computed tomography was adequate to guide the management of stable patients who could be treated conservatively, avoiding mandatory surgery in 34 patients and reducing the morbidity and mortality of non-therapeutic laparotomies.

Non-operative management for penetrating splenic trauma: how far can we go to save splenic function?

BACKGROUND

Selective non-operative management (NOM) for the treatment of blunt splenic trauma is safe. Currently, the feasibility of selective NOM for penetrating splenic injury (PSI) is unclear. Unfortunately, little is known about the success rate of spleen-preserving surgical procedures. The aim of this study was to investigate the outcome of selective NOM for penetrating splenic injuries.

METHODS

A dual-centre study is performed in two level-one trauma centres. All identified patients treated for PSI were identified. Patients were grouped based on the treatment they received. Group one consisted of splenectomised patients, the second group included patients treated by a spleen-preserving surgical intervention, and group three included those patients who were treated by NOM.

RESULTS

A total of 118 patients with a median age of 27 and a median ISS of 25 (interquartile range (IQR) 16-34) were included. Ninety-six patients required operative intervention, of whom 45 underwent a total splenectomy and 51 underwent spleen-preserving surgical procedures. Furthermore, 22 patients (12 stab wounds and 10 gunshot wounds) were treated by NOM. There were several anticipated significant differences in the baseline encountered. The median hospitalization time was 8 (5-12) days, with no significant differences between the groups. The splenectomy group had significantly more intensive care unit (ICU) days (2(0-6) vs. 0(0-1)) and ventilation days (1(0-3) vs. 0(0-0)) compared to the NOM group. Mortality was only noted in the splenectomy group.

CONCLUSIONS

Spleen-preserving surgical therapy for PSI is a feasible treatment modality and is not associated with increased mortality. Moreover, a select group of patients can be treated without any surgical intervention at all.

The diagnostic yield of commonly used investigations in pelvic gunshot wounds

BACKGROUND

Patients who sustain pelvic gunshot wounds (GSWs) are at significant risk for injury owing to the density of pelvic structures. Currently, the optimal workup for pelvic GSWs is unclear. The aims of this study were to determine the diagnostic yield of tests commonly used in the investigation of pelvic GSWs and to develop a diagnostic algorithm.

METHODS

All patients 15 years or older presenting to the Los Angeles County + University of Southern California Medical Center (January 2008 to February 2015) who sustained one or more pelvic GSWs were retrospectively identified. Patients' demographics, clinical assessment, investigations, procedures, and outcomes were abstracted. The diagnostic yield of computed tomographic (CT) scan, cystogram, gross inspection of the urine, urinalysis, endoscopy, and digital rectal examination (DRE) in the detection of clinically significant injuries to the pelvis were calculated.

RESULTS

Three hundred seventy patients were included. Patients with peritonitis, hemodynamic instability, an unevaluable abdomen, or evisceration were taken to the operating room for immediate laparotomy (n = 138 [37.3%]). All others (n = 232 [62.7%]) underwent CT scan and further investigations as indicated. The sensitivity, specificity, positive predictive value, and negative predictive value of the investigations were CT scan: 1.00, 0.98, 0.74, and 1.00; cystogram: 1.00 for all parameters; gross inspection of the urine: 1.00 for all parameters; urinalysis: 1.00, 0.71, 0.17, and 1.00; endoscopy: 1.00, 0.82, 0.75, and 1.00; and DRE: 0.77, 0.99, 0.77, and 0.99.

CONCLUSION

In the workup of pelvic GSWs, patients with hemodynamic instability, peritonitis, evisceration, or an unevaluable abdomen should undergo immediate laparotomy, while all others should undergo CT scan. Computed tomography-positive patients should be managed for their injuries. If the CT is negative, the likelihood of a clinically significant injury is very low. If the CT is equivocal for rectal or bladder injury, endoscopy or cystogram should be used to guide definitive management. There is no role for routine urinalysis or DRE. Further prospective validation of these findings is warranted.

WSES classification and guidelines for liver trauma

The severity of liver injuries has been universally classified according to the American Association for the Surgery of Trauma (AAST) grading scale. In determining the optimal treatment strategy, however, the haemodynamic status and associated injuries should be considered. Thus the management of liver trauma is ultimately based on the anatomy of the injury and the physiology of the patient. This paper presents the World Society of Emergency Surgery (WSES) classification of liver trauma and the management Guidelines.
