Nonoperative management of solid organ injuries in children results in decreased blood utilization

Spectrum of paediatric blunt abdominal trauma in a tertiary care hospital in India

Aim

To study the profile of paediatric blunt abdominal trauma and to assess the correlation of grade of injury with the outcome.

Materials and Methods

It is a prospective observational study from January 2015 to December 2020. Children below 12 years with blunt abdominal trauma were included. Patient demographic data, treatment given and the final outcome were recorded. All patients were followed up for a minimum of 6 months to maximum 5 years.

Results

A total of 68 patients were included in the study. Fall from height was the most common mode of injury (62%) followed by road traffic accidents (35%) and the other causes included in the miscellaneous group (hit by animal and fall of heavy object on the abdomen; 3%). Most commonly injured organ was liver (n = 28, 41%) followed by spleen (n = 18, 26%) and kidney (n = 15, 22%). Other injuries were bowel perforations (jejunal [n = 4], ileal [n = 1] and large bowel [n = 1]; 9%), pancreaticoduodenal (n = 5, 7%), urinary bladder (n = 3, 4%), abdominal vascular injury (iliac vein-1, inferior vena cava-1;3%), adrenal haematoma (n = 2,3%) and common bile duct (CBD) injury (n = 1, 1%). More than one organ injury was seen in 13 cases (19%). Non-operative management was successful in 84% (n = 27) and laparotomy was done in 16% (n = 11). Most of the patients sustained Grade IV injury (n = 36, 53%) and majority of the patients (n = 60, 88%) had good outcome without any long-term complications.

Conclusion

Profile of paediatric blunt abdominal trauma include solid organ injuries such as liver, spleen, kidney, pancreas, adrenal gland and others like bowel injury, CBD, urinary bladder and abdominal vascular injury. The grade of injury does not correlate with the outcome in a higher grade of injury and these children had good outcome.

The management and outcome of paediatric splenic injuries in the Netherlands

Background

Non-operative management (NOM) is generally accepted as a treatment method of traumatic paediatric splenic rupture. However, considerable variations in management exist. This study analyses local trends in aetiology and management of paediatric splenic injuries and evaluates the implementation of the guidelines proposed by the American Paediatric Surgical Association (APSA) in a level 1 trauma centre.

Methods

The charts of paediatric patients with blunt splenic injury (BSI) who were admitted or transferred to a level 1 trauma centre between 2003 and 2020 were retrospectively assessed. Information pertaining to demographics, mechanism of injury, injury description, associated injuries, intervention and outcomes were analysed and compared to international literature.

Results

There were 130 patients with BSI identified (63.1% male), with a mean age of 11.3 ± 4.0 and a mean Injury Severity Score (ISS) of 21.6 ± 13.7. Bicycle accidents were the most common trauma mechanism (23.1%). Sixty-four percent were multi-trauma patients, 25% received blood transfusions, and 31% were haemodynamically unstable. Mean injury grade was 3.0, with 30% of patients having a high-grade injury. In total, 75% of patients underwent NOM with a 100% efficacy rate. Total splenectomy rate was 6.2%. Four patients died due to brain damage.

Patients with a high-grade BSI (grades IV–V) had a significantly higher ISS and longer bedrest and more often presented with an active blush on computed tomography (CT) scans than patients with a low-grade BSI (grades I–III). Non-operative management was mainly the choice of treatment in both groups (76.6% and 79.5%, respectively). Haemodynamic instability was a predictor for operative management (OM) (p = 0.001). Predictors for a longer length of stay (LOS) included concomitant injuries, haemodynamic instability and OM (all p < 0.02). Interobserver agreement in the grading of BSI is moderate, with a Cohens Kappa coefficient of 0.493.

Conclusion

Non-operative management has proven to be a realistic management approach in both low- and high-grade splenic injuries. Consideration for operative management should be based on haemodynamic instability. Compared to the anticipated length of bedrest and hospital stay outlined in the APSA guidelines, the Netherlands can reduce the length of bedrest and hospital stay through their non-operative management.

Contemporary Management of Pediatric Blunt Splenic Trauma: A National Trauma Databank Analysis

PURPOSE

To quantify changes in the management of pediatric patients with isolated splenic injury from 2007 to 2015.

MATERIALS AND METHODS

Patients under 18 years old with registered splenic injury in the National Trauma Data Bank (2007-2015) were identified. Splenic injuries were categorized into 5 management types: nonoperative management (NOM), embolization, splenic repair, splenectomy, or a combination therapy. Linear mixed models accounting for confounding variables were used to examine the direct impact of management on length of stay (LOS), intensive care unit (ICU) days, and ventilator days.

RESULTS

Of included patients (n = 24,128), 90.3% (n = 21,789), 5.6% (n = 1,361), and 2.7% (n = 640) had NOM, splenectomy, and embolization, respectively. From 2007 to 2015, the rate of embolization increased from 1.5% to 3.5%, and the rate of splenectomy decreased from 6.9% to 4.4%. Combining injury grades, NOM was associated with the shortest LOS (5.1 days), ICU days (1.9 days), and ventilator days (0.5 day). Moreover, splenectomy was associated with longer LOS (10.1 days), ICU days (4.5 days), and ventilator days (2.1 days) than NOM. The average failure rate of NOM was 1.5% (180 failures/12,378 cases). Average embolization failure was 1.3% (6 failures/456 cases). Splenic artery embolization was associated with lower mortality than splenectomy (OR: 0.10, P <.001). No statistically significant difference was observed in mortality between embolization and NOM (OR: 0.96, P = 1.0).

CONCLUSIONS

In pediatric splenic injury, NOM is the most utilized and associated with favorable outcomes, most notably in grades III to V pediatric splenic injury. If intervention is needed, embolization is effective and increasingly utilized most significantly in lower grade injuries.

Pediatric Trauma: Management and Lessons Learned

Aim:

The aim is to prospectively study 125 trauma patients admitted in the pediatric surgery ward in our institute.

Materials and Methods:

Pediatric patients admitted in the ward after initial resuscitation in the triage room were included. Isolated neurosurgical and orthopedic injuries were excluded. X-ray cervical spine, hip, and chest and a focused assessment with sonography in trauma ultrasound were done for all patients. Computed tomography of the abdomen or chest was done where relevant. Injury profile and surgical intervention when needed were analyzed.

Results:

Road traffic accidents and fall from height caused 73.6% of the injuries. School-going children were most commonly affected (60.8%). Distinctive injuries were noted such as abdominal wall hernias and delayed bladder perforation. All solid organ injury irrespective of grade treated conservatively. Forty percent of the children required surgical intervention. Five patients after laparotomy were found to have surgical conditions unrelated to trauma, whereas another 14 required delayed surgery. Five patients had injuries secondary to sexual abuse. All except two patients were discharged in a satisfactory condition and are doing well in the follow-up.

Conclusion:

In spite of extensive injuries and the need for multiple surgeries, children with trauma have a good prognosis. Close observation during admission and also in follow-up are essential, as many patients may require delayed surgery ≥1 week from injury.

Outcome of children with blunt liver or spleen injuries: Experience from a single institution in Korea

INTRODUCTION

The aim of this study is to evaluate the demographics, injury pattern, and treatment outcomes among children hospitalized for the management of blunt liver and spleen injury at a single institution in Korea, and to document trends in treatment strategies of children with blunt torso trauma.

METHODS

Children (<20 years) with blunt liver and spleen injuries, hospitalized at our center between May 2010 and February 2016, were included in the present study. Data were retrospectively analyzed for demographic and injury-related information were obtained.

RESULTS

During the study period, 34 patients with blunt liver injury and 21 patients with blunt spleen injury presented at the center. The most common cause of liver and spleen injury was motor vehicle collision, followed by fall. Thirty patients (88.2%) with liver injuries and 18 patients (85.7%) with spleen injuries were managed conservatively. No cases of mortality occurred in patients with spleen injury group; one patient (2.9%) died in patients with liver injury due to uncontrolled bleeding.

CONCLUSIONS

Our data demonstrated that 85.7% of patients with spleen injuries and 88.2% of patients with liver injuries were managed nonoperatively. Operative management was chosen more selectively, being applied in patients with high grade organ injury scores or abrupt changes in vital status. Our findings will contribute to the available data concerning children with traumatic injuries in Korea.

The lost art of the splenorrhaphy

BACKGROUND

In the case of the hemodynamically unstable child, splenorrhaphy is preferred to splenectomy to avert postsplenectomy sepsis. However, successful splenorrhaphy requires familiarity with the procedure. We sought to determine how many splenectomies or splenorrhaphies for trauma the average pediatric surgeon can be expected to perform during their career.

METHODS

The Pediatric Health Information System (PHIS) Database was queried for patients ≤18years coded with an International Classification of Diseases 9th Edition diagnosis code of a splenic injury from 2004 to 2013. Age, gender, grade of splenic injury, and operations performed were extracted. Numbers of pediatric surgeons per hospital were obtained.

RESULTS

9567 children were identified. 2.1% underwent a splenectomy and 0.8% underwent a splenorrhaphy. The average surgeon performed 0.6 (SD=0.6) splenectomies and 0.2 (SD=0.4) splenorrhaphies for trauma. If these rates remain constant over time, the average surgeon would perform 1.8 (SD =1.7) splenectomies and 0.6 (SD =1.1) splenorrhaphies for trauma over a 30-year surgical career.

CONCLUSION

Nonoperative management is associated with a host of benefits, but has resulted in a decrease in the experience level of the pediatric surgeons expected to perform an emergency splenectomy or splenorrhaphy when the unusual occasion arises.

Pediatric Trauma: Current Concepts and Treatments

Injured children represent a complex management problem for the trauma surgeon. Physiologic and psychological factors have been shown to influence outcome; however, more importantly, injury patterns and treatment algorithms differ from those recommended for adults. Children often do well after major injuries, but surgeons must use appropriate treatment to maximize the physiologic responses and the innate healing abilities of the growing child. Historically, surgeons have defined childhood as prepubertal, but a child's physiologic response to injury extends well into the third decade of life, making treatment of a 20-year-old similar to that of a 10-year-old, rather than that of a 40-year-old. The distribution of pediatric trauma facilities across the country has limited the access of the injured child to these centers. Adult centers more often serve as the first and definitive treatment provider for children. This article reviews the current concepts of trauma treatments for children. It is hoped that the adult trauma surgeons caring for injured children might gain information that will be of assistance in their daily practice.

Factors Affecting Morbidity in Solid Organ Injuries

Background and Aim. The aim of this study was to investigate the effects of demographic characteristics, biochemical parameters, amount of blood transfusion, and trauma scores on morbidity in patients with solid organ injury following trauma. Material and Method. One hundred nine patients with solid organ injury due to abdominal trauma during January 2005 and October 2015 were examined retrospectively in the General Surgery Department of Dicle University Medical Faculty. Patients' age, gender, trauma interval time, vital status (heart rate, arterial tension, and respiratory rate), hematocrit (HCT) value, serum area aminotransferase (ALT) and aspartate aminotransferase (AST) values, presence of free abdominal fluid in USG, trauma mechanism, extra-abdominal system injuries, injured solid organs and their number, degree of injury in abdominal CT, number of blood transfusions, duration of hospital stay, time of operation (for those undergoing operation), trauma scores (ISS, RTS, Glasgow coma scale, and TRISS), and causes of morbidity and mortality were examined. In posttraumatic follow-up period, intra-abdominal hematoma infection, emboli, catheter infection, and deep vein thrombosis were monitored as factors of morbidity. Results. One hundred nine patients were followed up and treated due to isolated solid organ injury following abdominal trauma. There were 81 males (74.3%) and 28 females (25.7%), and the mean age was 37.6 ± 18.28 (15-78) years. When examining the mechanism of abdominal trauma in patients, the following results were obtained: 58 (53.3%) traffic accidents (22 out-vehicle and 36 in-vehicle), 27 (24.7%) falling from a height, 14 (12.9%) assaults, 5 (4.5%) sharp object injuries, and 5 (4.5%) gunshot injuries. When evaluating 69 liver injuries scaled by CT the following was detected: 14 (20.3%) of grade I, 32 (46.4%) of grade II, 22 (31.8%) of grade III, and 1 (1.5%) of grade IV. In 63 spleen injuries scaled by CT the following was present: grade I in 21 (33.3%), grade II in 27 (42.9%), grade III in 11 (17.5%), and grade IV in 4 (6.3%). The mean length of hospital stay after trauma was 6.46 days in the medically followed patients. This ratio was 8.13 days in 22 patients with morbidity and 5.98 days in 78 patients without morbidity. There was a morbidity in 22 (22%) patients medically followed after trauma. In this study, nonoperative treatment was observed to be performed safely in solid organ injuries after trauma in case of absence of hemodynamic stability and peritoneal irritation. It has been emphasized that injury of both liver and spleen (p < 0.01), high respiratory rate (p < 0.01), trauma scores (GKS, ISS, RTS) (p < 0.0001), and elevation of ALT AST values (p < 0.01) are stimulants for morbidity that may occur during follow-up. Conclusion. Medical follow-up can be considered in patients with high grade injuries similar to patients with low-grade solid organ injury after trauma. The injury of both liver and spleen, high respiratory rate, high GCS and ISS, low RTS, and elevation of ALT AST values were found to increase morbidity again in the follow-up of these patients.

Blunt Spleen and Liver Trauma

Blunt abdominal trauma is an important cause of pediatric morbidity and mortality. The spleen and liver are the most common abdominal organs injured. Trauma to either organ can result in life-threatening bleeding. Controversy exists regarding which patients should be imaged and the correct imaging modality depending on the level of clinical suspicion for injury. Nonoperative management of blunt abdominal trauma is the standard of care for hemodynamically stable patients. However, the optimal protocol to maximize patient safety while minimizing resource utilization is a matter of debate. Adjunctive therapies for pediatric spleen and liver trauma are also an area of ongoing research. A review of the current literature on the diagnosis, management, and follow-up of pediatric spleen and liver blunt trauma is presented.

More becomes less: management strategy has definitely changed over the past decade of splenic injury--a nationwide population-based study

Background. Blunt spleen injury is generally taken as major trauma which is potentially lethal. However, the management strategy has progressively changed to noninvasive treatment over the decade. This study aimed to (1) find out the incidence and trend of strategy change; (2) investigate the effect of change on the mortality rate over the study period; and (3) evaluate the risk factors of mortality. Materials and Methods. We utilized nationwide population-based data to explore the incidence of BSI during a 12-year study period. The demographic characteristics, including gender, age, surgical intervention, blood transfusion, availability of CT scans, and numbers of coexisting injuries, were collected for analysis. Mortality, hospital length of stay, and cost were as outcome variables. Results. 578 splenic injuries were recorded with an estimated incidence of 48 per million per year. The average 12-year overall mortality rate during hospital stay was 5.28% (29/549). There is a trend of decreasing operative management in patients (X², P = 0.004). The risk factors for mortality in BSI from a multivariate logistic regression analysis were amount of transfusion (OR 1.033, P < 0.001, CI 1.017–1.049), with or without CT obtained (OR 0.347, P = 0.026, CI 0.158–0.889), and numbers of coexisting injuries (OR 1.346, P = 0.043, CI 1.010–1.842). Conclusion. Although uncommon of BSI, management strategy is obviously changed to nonoperative treatment without increasing mortality and blood transfusion under the increase of CT utilization. Patients with more coexisting injuries and more blood transfusion had higher mortality.

Outcomes of blunt thoracic aortic injury in adolescents

BACKGROUND

Blunt traumatic aortic injury (BTAI) is of very rare occurrence in adolescents. The purpose of our study was to assess the clinical presentation and treatment outcomes of BTAI in this subset of patients.

METHODS

We reviewed prospective data of 18 patients who were 20 years or younger with BTAI among 28,000 trauma patients from January 1993 to December 2011. Outcomes of interest were the trends on the type of repair (nonoperative [NOP], open repair [OR], or endovascular treatment [ET]) and the impact of concomitant injuries using the Injury Severity Score (ISS) on early morbidity and mortality.

RESULTS

Thirteen (72%) patients with BTAI were male with a cohort median age of 16 ± 3 years. The mechanism of trauma was car accident in 12 patients, pedestrian struck by car in 5, and motorcycle crash in 1. The total ISS was 46.2 ± 15.3 being the highest score of the thoracic component (4.6 ± 0.6) followed by the head score (4 ± 1.2). Two (11%) patients were pronounced dead in the emergency department and other 2 succumbed within 24 hr from admission. Of those 14 (78%) patients who survived longer than 24 hr, the ISS was significantly lower compared with those pronounced dead earlier (37.8 ± 10.7 vs. 59.6 ± 11.6; P = 0.0009). Ten patients (71%) underwent OR, 3 (17%) ET, and other 2 (28%) patients were treated nonoperatively. The ISS was similar among all 3 treatment groups (OR: 33 ± 8 vs. ET: 53 ± 9 vs. NOP: 51 ± 6; P = nonsignificant). No paraplegia or renal failure was noted in either ET or OR group. In-hospital and overall mortality were 21% and 39%. Of those who survived hospitalization, 8 (73%) patients were discharged home and 3 (27%) to a rehabilitation center.

CONCLUSIONS

The incidence of BTAI is very low in adolescents. Mortality rate is considerable even in young patients and it is associated with high ISS and degree of aortic wall disruption. Young patients with BTAI who survive hospitalization have a lower ISS and are often discharged home rather than to a rehabilitation facility.

Pleural effusion following blunt splenic injury in the pediatric trauma population

BACKGROUND

Pleural effusion is a potential complication following blunt splenic injury. The incidence, risk factors, and clinical management are not well described in children.

METHODS

Ten-year retrospective review (January 2000-December 2010) of an institutional pediatric trauma registry identified 318 children with blunt splenic injury.

RESULTS

Of 274 evaluable nonoperatively managed pediatric blunt splenic injures, 12 patients (4.4%) developed left-sided pleural effusions. Seven (58%) of 12 patients required left-sided tube thoracostomy for worsening pleural effusion and respiratory insufficiency. Median time from injury to diagnosis of pleural effusion was 1.5days. Median time from diagnosis to tube thoracostomy was 2days. Median length of stay was 4days for those without and 7.5days for those with pleural effusions (p<0.001) and 6 and 8days for those pleural effusions managed medically or with tube thoracostomy (p=0.006), respectively. In multivariate analysis, high-grade splenic injury (IV-V) (OR 16.5, p=0.001) was associated with higher odds of developing a pleural effusion compared to low-grade splenic injury (I-III).

CONCLUSIONS

Pleural effusion following pediatric blunt splenic injury has an incidence of 4.4% and is associated with high-grade splenic injuries and longer lengths of stay. While some symptomatic patients may be successfully managed medically, many require tube thoracostomy for progressive respiratory symptoms.

Comparison of two treatment eras and sonographic long-term outcome of blunt splenic injuries in children

The treatment of blunt splenic injuries (BSI) has undergone a significant shift away from an operative approach to a conservative treatment regimen in the last decades. Data concerning long-term follow-up of children sustaining BSI are largely confined to telephone surveys. Children treated with BSI over a 33-year period were analyzed. In order to describe the changing treatment, patients were divided into two groups: group I included children treated between 1977 and 1999; group II children treated between 2000 and 2009. Additionally, patients treated nonoperatively between 2000 and 2009 were invited for a sonographic follow-up examination. In group I 81 patients and in group II 89 patients were treated. An increase of male patients from 69 to 88 % was observed, comparing the two eras. While children treated in the earlier period were 8.8-years-old mean (range 1 to 15), the patients treated between 2000 and 2009 were older (mean 10.4 years, range 1 to 17). Between 1977 and 1999, 79 % of the patients were treated nonoperatively. This rate considerably increased to 94 % in the second era. Follow-up examination was performed with a mean age of 6 years (range 1 to 11 years) post-injury. In 79 % of the cases, the spleen healed without sonographic long-term sequelae. In the remaining 21 % of the patients, a scar formation could be demonstrated.

CONCLUSION

We were able to confirm that the majority of children sustaining BSI can be safely treated conservatively.

Splenic conservation: variation between pediatric and adult trauma centers

OBJECTIVES

Nonoperative management of hemodynamically stable children and adolescents with splenic injury regardless of grade has become standard; however, numerous studies have shown a wide variation in management. We compared the treatment and outcomes of adolescent splenic injuries in our region, which includes a pediatric level I trauma center (PTC) and an adult level I trauma center (ATC).

METHODS

A retrospective review of the trauma registry was performed on patients 14 to 17 y old with blunt splenic injury admitted to either the local PTC or ATC from January 1999 through December 2010. Demographics, interventions, and hospital course were recorded and compared using Fisher exact, Student t-test, and multivariate analysis.

RESULTS

Eighty-six adolescent patients presenting to the PTC and 65 patients presenting to the ATC met the criteria over the 12-y period. Although the ATC received more significantly injured and slightly older patients, logistic multivariate analysis demonstrated that the location of presentation was the only independent factor associated with splenectomy (P = 0.0015). A higher injury severity score was associated with a longer length of stay (LOS), but the nonoperative approach was not associated with a longer LOS (P = 0.96).

CONCLUSIONS

Our study demonstrates that the location of presentation was independently associated with splenectomy while controlling for a higher injury severity score at the ATC. With the higher percentage of nonoperative management, treatment at the PTC was not associated with an increased LOS (total or intensive care unit).

Management of pediatric splenic injuries in Canada

PURPOSE

Nonoperative management (NOM) of blunt splenic injuries has become the standard of care in hemodynamically stable children. This study compares the management of these injuries between pediatric and nonpediatric hospitals in Canada.

METHODS

Data were obtained from the Canadian Institute of Health Information trauma database on all patients aged 2 to 16 years, admitted to a Canadian hospital with a diagnosis of splenic injury between May 2002 and April 2004. Variables included age, sex, associated major injuries, splenic procedures, intensive care unit (ICU) admissions, blood transfusions, and length of stay. Hospitals were coded as pediatric or nonpediatric. Univariate analysis and logistic regression were used to determine associations between hospital type and outcomes.

RESULTS

Of 1284 cases, 654 were managed at pediatric hospitals and 630 at nonpediatric centers. Patients at pediatric centers tended to be younger and more likely to have associated major injuries. Controlling for covariates, including associated major injuries, patients managed at pediatric centers were less likely to undergo splenectomy compared with those managed at nonpediatric centers (odds ratio [OR], 0.2; 95% confidence interval, 0.1-0.4). The risk of receiving blood products, admission to the ICU, and staying in hospital for more than 5 days was associated only with having associated major injuries.

CONCLUSION

Even in the presence of other major injuries, successful NOM of blunt splenic injuries occurs more frequently in pediatric hospitals in Canada. This has policy relevance regarding education of adult surgeons about the appropriateness of NOM in children and developing guidelines on appropriate regional triaging of pediatric patients with splenic injury in Canada.

Blunt splenic injury in Sikkimese children and adolescents

Background:

The contemplation for the salvage operations and the nonoperative treatment for the pediatric splenic injuries had increasingly been suggested as the standard case management.

Objectives:

The study was carried out to identify the risk factors, the presentations, the severities and outcome of the interventions of blunt splenic injuries in the children and adolescents.

Materials and Methods:

This retrospective review was carried out in a tertiary care hospital in Sikkim on the children and adolescents admitted with splenic injury from January 2005 to December 2009. Splenic injuries were graded with the American Association for the Surgery of Trauma Splenic Injury Scale followed by the operative and nonoperative managements (NOM).

Results:

Overall 147 cases with the abdominal trauma were diagnosed with splenic injury. Of them, males reported in higher numbers; three-fourths were adolescents with preponderance above 16 years of age. Majority of the cases [n=91(61.90%)] were due to fall from heights and others from road traffic accidents. Immediate surgical interventions was instituted in the hemodynamically unstable cases (n=87) NOM failed in 27 patients; of them eight cases underwent splenectomy, and 19 underwent surgical salvage; 33 were closely followed up by conservative approach with both clinical and CT criteria. Total number of cases in grade III and above was significantly higher than with lower grades of injury.

Conclusions:

In total 95(64.63%) of the cases were managed with total splenectomy; 19 cases in the initial nonsurgical group underwent salvage operation and 33 cases received NOM.

In-Hospital Treated Pediatric Injuries are Increasing in Finland — A Population Based Study between 1997 AND 2006

Background and Aims:

Injuries are an important public health problem as well as the leading cause of death and disability among children. Our aim was to longitudinally explore the incidence of in-hospital treated traumas, their operative treatment and related mortality among pediatric patients in Finland.

Methods:

The National Hospital Discharge Register and the Official Cause-of-Death Statistics data of in-hospital treated pediatric trauma patients between 1997 and 2006 in Finland were evaluated for hospitalizations, treatment modality and mortality.

Results:

Fractures (69%) and head injuries (28%) were the most common in-hospital treated traumas (477/100 000 persons/year). These were followed by injuries of intra-abdominal (1.4%), thoracic (1.2%) and urological organs (0.6%). Head traumas constituted 67% of injury-related deaths. During the ten-year follow-up period, the annual incidence (per 100 000 persons) of head injuries decreased by 13.6% (152 in 1997 vs. 131 in 2006, p < 0.0001) mainly contributing to a 30% decrease in overall injury-related mortality incidence (from 5.7 in 1997 to 4.0 in 2006, p = 0.0519). The overall trauma incidence, and incidence of fractures and abdominal injuries significantly increased by 5.0% (p < 0.0001), 13.5% (p < 0.0001) and 37% (p < 0.05), respectively, while the incidence of thoracic and urological injuries remained unchanged. Up to 15% of spleen injuries lead to splenectomy.

Conclusions:

Although overall and head trauma-related mortality is decreasing, the increasing incidence of fractures and abdominal injuries has amplified the overall incidence of severe injuries among children in Finland. A significant number of unnecessary splenectomies are still performed among children.

Long-term follow-up of children with nonoperative management of blunt splenic trauma

BACKGROUND

: The effectiveness of nonoperative management (NOM) of blunt splenic injuries (BSIs) in children is established; however, only limited data of their long-term follow-up exist. We hypothesize that long-term follow-up verifies that NOM of BSI in children is safe and effective.

METHODS

: From 1993 to 2008, 153 children (1-17 years, mean = 12) with BSI were admitted. Patients were contacted by telephone and answered a standardized questionnaire. Medical records were reviewed to validate injury grade, hospital stay, and complications.

RESULTS

: Eighty patients (52%) participated; 18 were excluded (8 splenectomies, 2 splenorraphies, 3 comatose, 2 language barriers, and 3 with unavailable records). Mean follow-up of the remaining 62 patients was 74 months (range, 5-165 months). There were 9 grade I, 9 grade II, 22 grade III, 20 grade IV, and 2 grade V injuries. Mechanism of injury was motor vehicle crashes (14), falls (11), all terrain vehicle (ATV) crashes (10), snow recreation related (14), and other recreation (13). Two patients were readmitted for spleen complications (splenic cyst and hematoma), but neither required additional treatment. Seven patients reported potential spleen-related complications: six immunologic (asthma, rashes, and increased illness), two abdominal pain, and two psychiatric related to fear of reinjuring their spleen. Three children sustained a second BSI, and none required surgical intervention.

CONCLUSIONS

: Long-term follow-up indicates that our protocol for NOM of BSI in children is safe, including secondary injuries. However, this study indicates that children who sustain BSI may require more counseling than presently provided. With an intact spleen, fear of immunologic dysfunction is irrational and indicates a lack of understanding at discharge. In addition, more intensive investigation and interventions for families that may suffer from posttraumatic stress disorder or related disorders appears indicated.

Pediatric blunt splenic trauma: a comprehensive review

Abdominal trauma is a leading cause of death in children older than 1 year of age. The spleen is the most common organ injured following blunt abdominal trauma. Pediatric trauma patients present unique clinical challenges as compared to adults, including different mechanisms of injury, physiologic responses, and indications for operative versus nonoperative management. Splenic salvage techniques and nonoperative approaches are preferred to splenectomy in order to decrease perioperative risks, transfusion needs, duration/cost of hospitalization, and risk of overwhelming postsplenectomy infection. Early and accurate detection of splenic injury is critical in both adults and children; however, while imaging findings guide management in adults, hemodynamic stability is the primary determinant in pediatric patients. After initial diagnosis, the primary role of imaging in pediatric patients is to determine the level and duration of care. We present a comprehensive literature review regarding the mechanism of injury, imaging, management, and complications of traumatic splenic injury in pediatric patients. Multiple patients are presented with an emphasis on the American Association for the Surgery of Trauma organ injury grading system. Clinical practice guidelines from the American Pediatric Surgical Association are discussed and compared with our experience at a large community hospital, with recommendations for future practice guidelines.

Disparities in the delivery of pediatric trauma care

BACKGROUND

Trauma is the leading cause of morbidity and mortality in children. During the last few decades, trauma systems have evolved to improve the care of the injured with an ultimate goal of saving lives. As a result, pediatric trauma centers (PTC) have been established to optimize outcomes for injured children. We sought to determine whether injured children treated at PTC or adult trauma centers (ATC) with added qualifications to treat injured children receive better trauma care than those treated at other hospitals or trauma centers.

METHODS

We reviewed more than 60 published studies on pediatric trauma outcomes. The studies included registry analysis: single and multihospital experience; abdominal, head and neck, and thoracic trauma; as well as functional outcomes.

RESULTS

The data show that most injured children are not treated at PTC due to the geographically limited distribution of such specialized care, lack of pediatric surgeons, and other specialists. These limitations create persistent disparities in outcomes for injured children depending on where they are treated. Some of the larger database analyses suggest lower mortality rate, better outcome for nonoperative treatment of blunt abdominal injuries, and improved overall functional outcome for those children treated at PTC. However, others fail to demonstrate differences for children treated at ATC or ATC with added qualifications.

CONCLUSION

Although this analysis does not provide a definitive answer to the question as to which type of trauma center provides better care for injured pediatric patients, it identifies current gaps and disparities in the care of injured children that can be remedied through education and training.

Management of pediatric blunt splenic injuries in Canada--practices and opinions

PURPOSE

The aim of the study was to compare the self-reported practice patterns of Canadian general surgeons (GSs) and pediatric general surgeons (PGSs) in treating blunt splenic injuries (BSIs) in children.

METHODS

Forty-five PGSs and 690 GSs were surveyed (internet and hard copy). chi(2) was used to compare groups; logistic regression was performed to determine independent factors influencing management variables.

RESULTS

Thirty-three PGSs and 191 GSs completed the survey, for a response rate of 30%. Pediatric general surgeons are more likely than GSs to follow American Pediatric Surgical Association guidelines (52% vs 11%; P < .0001). In diagnosing BSIs, PGSs and GSs are equally likely to use computed tomography (CT) over ultrasound for initial imaging. Pediatric general surgeons are less likely to consider CT injury grade in deciding on nonoperative management (NOM) (odds ratio [OR], 0.2; confidence interval [CI], 0.07-0.5; P = .002) and are more likely to continue NOM for patients with contrast blush on CT (OR, 6.5; CI, 2.5-17; P = .0002). Pediatric general surgeons report more selective intensive care unit use, hospital stay, follow-up imaging, and activity restrictions. No differences were found in the management of splenic artery pseudoaneurysms.

CONCLUSION

Differences exist between PGSs and GSs in the management of pediatric BSIs, resulting in higher operative rates, use of resources, and radiation exposure. Further education of GSs in NOM and establishment of management guidelines are indicated.

Review of the evidence on the management of blunt renal trauma in pediatric patients

Due to the size and location within the pediatric patient, the kidneys are susceptible to injury from blunt trauma. While it is clear that the goal of management of blunt renal trauma in children is renal preservation, the methods of achieving this goal have not been well established in the current literature. Therefore, we have set out to summarize and clarify the current published information on the management strategies for blunt renal trauma in children. While there is extensive literature available, it consists mostly of retrospective series documenting widely varied management styles. The purpose of this review is to display the current information available and delineate the role for future studies that may allow us to develop consistent management strategies of pediatric patients, who have sustained blunt renal trauma, in a safe and cost-effective manner.

Blunt solid organ injury: do adult and pediatric surgeons treat children differently?

BACKGROUND

The management of blunt solid organ injury (SOI) in children may differ depending on the treating facility. These differences, however, may not reflect the individual surgeon's treatment philosophy. To investigate differences in management, adult and pediatric surgeons were presented the same hypothetical pediatric trauma "patient" and asked a series of treatment questions.

METHODS

By using an internet-based survey, members of American Association for the Surgery of Trauma, American Academy of Pediatrics, and Eastern Association of the Surgery of Trauma were invited to participate anonymously. Surgeons who "never or rarely saw children" and those who "would transfer the patient to another facility" were excluded. Demographic, educational, and practice data were collected. Scenarios of increasing complexity were presented with CT images (isolated SOI, multiple SOI, and SOI with intracranial hemorrhage [ICH]). For each scenario, respondents were asked if they would initially manage the patient nonoperatively, pursue angiography, or operate. Scenarios were repeated with the addition of a CT "blush." For patients managed nonoperatively, respondents were asked their transfusion threshold needed to operate. Responses were compared using exact chi tests and risk ratios.

RESULTS

Two hundred eighty-one surgeons (114 pediatric, 167 adult) were included. For all scenarios, adult surgeons were more likely to operate or pursue embolization than their pediatric colleagues (RR: 8.6 SOI, 14.8 multiple SOI, 17.9 SOI with ICH). Adult surgeons were also more likely to consider any transfusion a failure (13.3% vs. 1.2%, p < 0.01) and had a much lower transfusion threshold.

CONCLUSION

When presented with the identical clinical scenario, adult trauma surgeons are less likely than pediatric surgeons to pursue nonoperative management of pediatric solid organ injuries and are more conservative in their willingness to transfuse.

Management of High-Grade Splenic Injury in Children

Using the National Trauma Databank, we identified 413 children (age ≤ 14 years) who sustained high-grade blunt splenic injury (Abbreviated Injury Scale scores ≥4) from 2001 to 2005. Overall mortality was 13.5 per cent. Early operation within 6 hours of injury (EOM) was performed in 128 patients (31%). Patients not undergoing EOM (n = 285) were assumed to have been treated with initial nonoperative management (NOM). NOM was successful in 84 per cent of patients. Operative intervention was necessary in 42 per cent of cases with 74 per cent of these undergoing early operation (EOM). Total splenectomy was the most common procedure (83%). EOM and failure of NOM were both associated with lower systolic blood pressure and lower Glasgow Coma Scale score at admission, higher Injury Severity Score, longer hospital stay, and higher mortality. Need for surgery was independent of patient age and gender. Failure of NOM was associated with increased mortality compared with successful NOM, but had similar mortality and length of hospital or intensive care unit stay compared with EOM. We conclude that operative treatment is necessary in nearly half of pediatric patients with high-grade splenic injury. With careful selection, nonoperative management is usually successful but must include close monitoring, because 16 per cent required delayed operation.

Injuries Associated with Pediatric Liver Trauma

Injury remains the leading cause of childhood mortality for children younger than 14 years of age, with the liver being particularly susceptible to blunt trauma in children. This study reviews the authors’ institutions’ experience with pediatric liver injuries in an attempt to establish current patterns of injury, management and outcomes. A single-center, retrospective review was conducted of 105 consecutive pediatric patients who presented with a traumatic liver injury from January 1996 through February 2004. Average patient age was 13.1 ± 4.9 years and 58 per cent were male. Perihospital mortality was 8.6 per cent, with 67 per cent of mortality being attributed to head injury. The majority of patients were managed nonoperatively (81%). Liver injury was most often grade II (35%) by CT scan. Liver injury grade did not affect survival, but did affect injury management, with grade I and grade IV liver injuries more likely to be managed surgically ( P < 0.001). Grade I liver injuries were associated with concomitant spleen injuries, whereas grade IV injuries were associated with pancreatic injuries. Surgical management was associated with a higher injury severity score ( P = 0.005), higher mortality ( P = 0.01), and with other associated injuries as well. Children experiencing blunt abdominal trauma are at risk of significant morbidity and mortality; however, these risks stem more likely from associated injuries than injury to the liver proper. Clinicians should maintain a high index of suspicion for potentially catastrophic associated injuries to the pancreas with high-grade liver injury.

Variation in the Management of Pediatric Splenic Injuries in the United States

BACKGROUND

This study examines the existence and sources of variation in the management of pediatric splenic injuries among hospitals in the United States and the factors associated with splenectomy.

METHODS

Information on children 15 years of age and younger with a splenic injury diagnosis code was extracted from the Kids' Inpatient Database 2000, a pediatric inpatient database of 2,784 hospitals in 27 states covering 72% of the nation's population for the year 2000. Patient variables included age, sex, race, injury diagnoses, grade of splenic injury, splenic procedure code, and calculated Injury Severity Score. Hospital variables included pediatric status (free-standing, unit and adult), teaching status, annual pediatric splenic trauma volume, and national region. A multivariate logistic regression model was used to predict the factors associated with splenectomy based upon patient and hospital characteristics.

RESULTS

In all, 2,191 children with splenic injuries were identified; 253 (12%) underwent splenectomy. The crude rate of splenectomy varied significantly among pediatric hospital types: 3% (11/339) at freestanding children's hospitals, 9% (45/525) at unit hospitals and 15% (197/1327) at adult hospitals (p < 0.001). Risk of splenectomy increased with the grade of splenic injury, patient age, and the presence of multiple injuries. Teaching hospitals and hospitals with higher patient volume were associated with lower risk for splenectomy. There was no relationship between splenectomy and gender, race, or national region. Despite adjustment for the above noted hospital and patient-specific variables, children treated at an adult hospital had 2.8 times the odds, and those treated at a unit pediatric hospital 2.6 times the odds, of undergoing splenectomy as those cared for at a free-standing pediatric hospital (p = 0.003 and 0.013, respectively).

CONCLUSION

Nationally, children cared for at freestanding pediatric hospitals have a significantly lower risk of splenectomy than children treated at either adult hospitals or pediatric hospitals within an adult hospital. This may have implications for education, trauma triage and the establishment of practice guidelines.

Pediatric blunt abdominal trauma

Blunt pediatric trauma is a major threat to the health and well-being of children. Nationwide, many practitioners care for children who face this issue. Some key principles related to the evaluation and management of these children are elucidated in this article.

Variation in Treatment of Pediatric Spleen Injury at Trauma Centers Versus Nontrauma Centers: A Call for Dissemination of American Pediatric Surgical Association Benchmarks and Guidelines

BACKGROUND

American Pediatric Surgical Association consensus guidelines for children with blunt spleen injuries have been defined and validated in children's hospitals, but large administrative data sets indicate that only 10% to 15% of children with blunt spleen injuries are treated at children's hospitals. We sought to identify the frequency and compare the treatment of children with spleen injury in hospitals with and without recognized trauma expertise, with the aim of identifying a meaningful target for dissemination of benchmarks and consensus guidelines.

STUDY DESIGN

State health departments' administrative data sets from California, Florida, New Jersey, and New York were analyzed for 2000, 2001, and 2002. All children with head injury or other nonspleen abdominal injuries requiring surgery were excluded. Injury Severity Scores were determined by ICDMAP-90.

RESULTS

There were 3,232 patients with blunt spleen injury. Trauma centers had a significantly lower rate of operation for both multiply injured patients (15.3% versus 19.3%, p < 0.001) and those with isolated injury (9.2% versus 18.5%, p < 0.0001) when compared with nontrauma centers. The operative rates at both trauma centers and nontrauma centers exceed published American Pediatric Surgical Association benchmarks for all children with spleen injury (5% to 11%) and the subset with isolated spleen injury (0% to 3%). Independent risk factors for splenectomy included ages 15 to 19 years (p < 0.002), spleen injury severity (p < 0.0001), and presence of multiple injuries (p < 0.04). Adjusted odds ratio for risk of splenic operation in all patients with spleen injury was 2.122 (95% CI:1.455- 3.096) when treated at a nontrauma center (p < 0.0001).

CONCLUSIONS

These multistate discharge data indicate that treatment of children with blunt spleen injury differs significantly when comparing trauma centers and nontrauma centers. Because nearly two-thirds of these children were treated at trauma centers, dissemination of American Pediatric Surgical Association guidelines and benchmarks through state or regional trauma systems may reduce the number of children having operations for splenic injury.

The Failure of Nonoperative Management in Pediatric Solid Organ Injury: A Multi-institutional Experience

BACKGROUND

Nonoperative management (NOM) is the accepted treatment of most pediatric solid organ injuries (SOI) and, is typically successful. We sought to elucidate predictors of, and the time course to, failure in the subset of children suffering SOI who required operative intervention.

METHODS

A retrospective analysis was performed from January 1997 through December 2002 of all pediatric patients (age 0-20 years) with a SOI (liver, spleen, kidney, pancreas) from the trauma registries of seven designated, level I pediatric trauma centers. Failure of NOM was defined as the need for intra-abdominal operative intervention. Data reviewed included demographics, injury mechanism, injury severity (ISS, AIS, SOI grade, and GCS), and outcome. For the failures of NOM, time to operation and relevant clinical variables were also abstracted. A summary AIS (sAIS) was calculated for each patient by summing the AIS values for each SOI, to account for multiple SOI in the same patient. Univariate and multivariate analyses were employed, and significance was set at p < 0.05.

RESULTS

A total of 1,880 children were identified. Of these, 62 sustained nonsurvivable head injuries that precluded assessment of NOM outcome and were thus excluded. The remaining 1,818 patients comprised the overall study population. There were 1,729 successful NOM patients (controls -- C) and 89 failures (F), for an overall NOM failure rate of 5%. For isolated organ injuries, the failure rates were: kidney 3%, liver 3%, spleen 4%, and pancreas 18%. There were 14 deaths in the failure group from nonsalvageable injuries (mean ISS = 54 +/- 15). The two groups did not differ with respect to mean age or gender. An MVC was the most common injury mechanism in both groups. Only bicycle crashes were associated with a significantly increased risk of failing NOM (RR = 1.76, 95% CI = 1.02-3.04, p < 0.05). Injury severity and organ specific injuries were associated with NOM failure. When controlling for ISS and GCS, multivariate regression analysis confirmed that a sAIS > or = 4, isolated pancreatic injury, and >1 organ injured were significantly associated with NOM failure (p < 0.01). The median time to failure was 3 hours (range, 0.5-144 hours) with 38% having failed by 2 hours, 59% by 4 hours, and 76% by 12 hours.

CONCLUSIONS

Failure of NOM is un common (5%) and typically occurs within the first 12 hours after injury. Failure is associated with injury severity and multiplicity, as well as isolated pancreatic injuries.

Trends in operative management of pediatric splenic injury in a regional trauma system

OBJECTIVE

Selective nonoperative management of pediatric blunt splenic injury became the standard of care in the late 1980s. The extent to which this practice has been adopted in both trauma centers and nontrauma hospitals has been investigated sporadically. Several studies have demonstrated significant variations in practice patterns; however, most published studies capture only a selective population over a relatively short time interval, often without simultaneous adjustment for confounding variables. The objective of this study was to characterize the variation in operative versus nonoperative management of blunt splenic injury in children in nontrauma hospitals and in trauma centers with varying resources for pediatric care within a regionalized trauma system in the past decade.

METHODS

The study population included all children who were younger than 19 years and had a diagnosis of blunt injury to the spleen (International Classification of Diseases code 865.00-865.09) and were admitted to each of the 175 acute care hospitals in Pennsylvania between 1991 and 2000. The proportion of patients who were treated operatively was stratified by trauma-level certification and adjusted for age and splenic injury severity. Multivariable logistic regression models were used to generate probabilities of splenectomy by age, injury severity, and hospital type.

RESULTS

From 1991 through 2000 in Pennsylvania, 3245 children sustained blunt splenic injury that required hospitalization; 752 (23.2%) were treated operatively. Generally, as age and splenic injury severity increased, the proportion of patients who were treated operatively increased. Compared with pediatric trauma centers, the relative risk (with associated 95% confidence interval) of splenectomy was 4.4 (3.0-6.3) for level 1 trauma centers with additional qualifications in pediatrics; 6.2 (4.4-8.7) for level 1 trauma centers, 6.3 (5.3-7.4) for level 2 trauma centers, and 5.0 (4.2-5.9) for nontrauma centers. Significant variation in practice pattern was seen among hospital types and over time even after adjustment for age and injury severity.

CONCLUSIONS

The operative management of splenic injury in children varied significantly by hospital trauma status and over time during the past decade in Pennsylvania. Given the relative benefits of nonoperative treatment for children with blunt splenic injury, these results highlight the need for more widespread and standardized adoption of this treatment, particularly in hospitals without a large volume of pediatric trauma patients.

Variation in the Management of Pediatric Splenic Injuries in New England

BACKGROUND

Nonoperative management of stable children with splenic injuries is the standard of care but has been variably applied in New England. The influence of surgeon training on this variation was analyzed.

METHODS

A region-wide administrative data set was queried for children with a splenic injury from 1990 through 1998. The influence of a range of patient- and hospital-specific variables, including surgeon pediatric training, on the risk of operation was analyzed.

RESULTS

The risk of operation increased with age, severity of splenic injury, and the presence of multiple injuries, but also trauma center status and the presence of a surgical training program. After allowance for these variables, the risk of operation was reduced by half when children with splenic injuries were cared for by a surgeon with pediatric specialty training.

CONCLUSION

The risk of operation for pediatric splenic injury in New England is dependent on several variables, including the surgeon's training.

Abdominal and pelvic trauma in children

Trauma is the leading cause of death and disability in children. More than 90% of pediatric trauma admissions are the result of a blunt mechanism. Although injury to the abdomen and pelvis account for only 10% of injuries sustained by victims of pediatric trauma, they can be potentially life threatening. Optimal evaluation of the injured child may require the use of multiple diagnostic modalities. The spleen is the most frequently injured intra-abdominal organ, followed by the liver, intestine, and pancreas. Fortunately, the majority of injuries to the spleen and liver can be treated nonoperatively. Conversely, injuries involving the intestine and pancreas often require operative intervention.
