RESUMO

The radiologic finding of focal stenosis of the main pancreatic duct is highly suggestive of pancreatic cancer. Even in the absence of a mass lesion, focal duct stenosis can lead to surgical resection of the affected portion of the pancreas. We present four patients with distinctive pathology associated with non-neoplastic focal stenosis of the main pancreatic duct. The pathology included stenosis of the pancreatic duct accompanied by wavy, acellular, serpentine-like fibrosis, chronic inflammation with foreign body-type giant cell reaction, and calcifications. In all cases, the pancreas toward the tail of the gland had obstructive changes including acinar drop-out and interlobular and intralobular fibrosis. Three of the four patients had a remote history of major motor vehicle accidents associated with severe abdominal trauma. These results emphasize that blunt trauma can injure the pancreas and that this injury can result in long-term complications, including focal stenosis of the main pancreatic duct. Pathologists should be aware of the distinct pathology associated with remote trauma and, when the pathology is present, should elicit the appropriate clinical history.

RESUMO

INTRODUCTION: The single most important predictor of pancreas-specific complications (PSCs) after pancreatic trauma is injury to the main pancreatic duct (MPD). Pancreatography has been recommended to evaluate the integrity of the MPD. In addition, pancreatic duct stents have been proposed to prevent or treat PSC. The primary purpose of this study was to determine the accuracy of magnetic resonance cholangiopancreatography (MRCP) in diagnosing MPD injury. We further sought to determine whether stents were effective in preventing PSC or facilitated the resolution of pancreatic leaks or fistulae. METHODS: A secondary analysis of a multicenter retrospective review of pancreatic injuries in patients 15 years and older from 2010 to 2018, focusing on patients who underwent MRCP or endoscopic retrograde cholangiopancreatography (ERCP), was performed. Final pancreatic injury grade was determined based on all available assessments, ultimately adjudicated by the site principal investigator. Data were analyzed using various statistical tests where appropriate. RESULTS: Thirty-three centers reported on 1,243 patients. A total of 216 underwent pancreatography-137 had MRCP and 115 ERCP, with 36 having both. The sensitivity of MRCP for MPD injury was 37%, the specificity was 94%, the positive predictive value was 77%, and the negative predictive value was 73%. When compared with ERCP, MRCP findings were discordant in 64% of cases. Pancreatic stents were placed in 77 patients; 48 (62%) were to treat PSC, with no clear benefit. Twenty-nine had prophylactic stents placed. There did not appear to be benefit in reduced PSC compared with the entire study group or among patients with high-grade pancreatic injuries. CONCLUSION: The accuracy of MRCP to evaluate the integrity of the MPD does not appear to be superior to computed tomography scan. Consequently, the results of MRCP should be interpreted with caution. The current data do not support prophylactic use of pancreatic stents; they should be studied in a prospective trial. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

RESUMO

INTRODUCTION: Despite bladder perforation (BP) is a frequent complication during transurethral resection of bladder (TURB) for bladder cancer (BCa), literature lacks systematic reviews focusing on this issue. We aimed to investigate incidence, diagnosis, therapy, and prognosis after BP during TURB for BCa; therapy was distinguished between conservative (without the need for bladder repair) and surgical management (requiring bladder wall closure). EVIDENCE ACQUISITION: A systematic search was conducted up to April 2021 using PubMed, Scopus, Cochrane Database of Systematic Reviews, and Web of Science to identify articles focusing on incidence, detection, management, or survival outcomes after iatrogenic BP. The selection of articles followed the preferred reporting items for systematic review and meta-analyses process. EVIDENCE SYNTHESIS: We included 41 studies, involving 21,174 patients. Overall, 521 patients experienced BP during TURB for BCa, with a mean incidence of 2.4%, up to 58.3% when postoperative cystography is routinely performed after all TURB procedures. Risk factors were low body mass index (BMI) (P=0.01), resection depth (P=0.006 and P=0.03), and low surgical experience (P=0.006). Extraperitoneal BP (68.5%) were treated conservatively in 97.5% of patients; intraperitoneal BP were managed with surgical bladder closure in 56% of cases. Overall, three immediate BP-related deaths were recorded due to septic complications. Extravesical tumor seeding was observed after 6 intraperitoneal and 1 extraperitoneal BP (median time: 6.2 months). Intraperitoneal BP (P=0.0003) and bladder closure (P<0.001) were found as independent predictors of extravesical tumor recurrence. CONCLUSIONS: BP is more frequent than expected when proper diagnosis is routinely performed after all TURB procedures. Risk factors include low BMI, resection depth, and unexperienced surgeon. The risk of sepsis after BP suggests empirical antibiotic prophylaxis after BP.

RESUMO

Polyploidy frequently arises in response to injury, aging, and disease. Despite its prevalence, major gaps exist in our understanding of how polyploid cells alter tissue function. In the adult Drosophila epithelium, wound healing is dependent on the generation of multinucleated polyploid cells resulting in a permanent change in the epithelial architecture. Here, we study how the wound-induced polyploid cells affect tissue function by altering epithelial mechanics. The mechanosensor nonmuscle myosin II is activated and upregulated in wound-induced polyploid cells and persists after healing completes. Polyploidy enhances relative epithelial tension, which is dependent on the endocycle and not cell fusion post injury. Remarkably, the enhanced epithelial tension mimics the relative tension of the lateral muscle fibers, which are permanently severed by the injury. As a result, we found that the wound-induced polyploid cells remodel the epithelium to maintain fly abdominal movements, which may help compensate for lost tissue tension.

RESUMO

BACKGROUND: Intestinal transplantation (ITx) is performed as an isolated ITx or as a part of multivisceral transplantation for intestinal failure secondary to short gut syndrome, inflammatory bowel disease, trauma, and sequelae of chronic parenteral nutrition dependence. Wound complications after ITx are very common, and abdominal wound closure cannot be immediately achieved in half of cases. CASE PRESENTATION: A 25-year-old man sustained an abdominal crush injury causing complete loss of his small intestine, requiring an isolated ITx in March 2016. He lost his graft because of early exfoliative rejection in November 2016. Five months after enterectomy and the immunosuppression-free period, he underwent multivisceral retransplantation in April 2017. His post-transplant course was complicated by wound healing problems that improved with treatment of his malnutrition, quantified by increasing albumin, total protein, prealbumin, weight, body mass index, and total psoas muscle area over a period of 19 months after retransplant. CONCLUSION: To our knowledge, this is the first case described of long-term wound follow-up after a multivisceral (re)transplantation, with corresponding nutrition information and images of the wound.

RESUMO

BACKGROUND: Indications for intervention after high-grade renal trauma (HGRT) remain poorly defined. Certain radiographic findings can be used to guide the management of HGRT. We aimed to assess the associations between initial radiographic findings and interventions for hemorrhage after HGRT and to determine hematoma and laceration sizes predicting interventions. METHODS: The Genitourinary Trauma Study is a multicenter study including HGRT patients from 14 Level I trauma centers from 2014 to 2017. Admission computed tomography scans were categorized based on multiple variables, including vascular contrast extravasation (VCE), hematoma rim distance (HRD), and size of the deepest laceration. Renal bleeding interventions included angioembolization, surgical packing, renorrhaphy, partial nephrectomy, and nephrectomy. Mixed-effect Poisson regression was used to assess the associations. Receiver operating characteristic analysis was used to define optimal cutoffs for HRD and laceration size. RESULTS: In the 326 patients, injury mechanism was blunt in 81%. Forty-seven (14%) patients underwent 51 bleeding interventions, including 19 renal angioembolizations, 16 nephrectomies, and 16 other procedures. In univariable analysis, presence of VCE was associated with a 5.9-fold increase in risk of interventions, and each centimeter increase in HRD was associated with 30% increase in risk of bleeding interventions. An HRD of 3.5 cm or greater and renal laceration depth of 2.5 cm or greater were most predictive of interventions. In multivariable models, VCE and HRD were significantly associated with bleeding interventions. CONCLUSION: Our findings support the importance of certain radiographic findings in prediction of bleeding interventions after HGRT. These factors can be used as adjuncts to renal injury grading to guide clinical decision making. LEVEL OF EVIDENCE: Prognostic and Epidemiological Study, Level III and Therapeutic/Care Management, Level IV.

RESUMO

Clamshell thoracotomy for thoracic injuries is an uncommon emergency department procedure. The survival rates following emergency thoracotomy are very low at 9%-12% for penetrating trauma and 1%-2% for blunt trauma. We report an unusual case of survival after emergency department clamshell thoracotomy for penetrating thoracic trauma with cardiac tamponade in a 23-year-old man with multiple stab wounds on the chest and abdomen. The patient was awake and alert on arrival in the emergency department. Bilateral chest decompression by needle thoracostomy released air and blood. During subsequent chest drain insertion, the patient suddenly deteriorated and arrested. Clamshell thoracotomy was performed, and sinus rhythm restored before transfer to theatre. Following repair of the thoracic injuries, a midline laparotomy was performed as bleeding was suspected from the abdomen and a splenic injury repaired. The patient survived and has made a full recovery. This case demonstrates how clamshell thoracotomy can be a life-saving procedure.

RESUMO

We present the first report of pneumopericardium observed by autopsy and on postmortem computed tomography (PMCT) images. The subject was a woman who died of self-inflicted stab wounds to the abdomen. The PMCT scan revealed air in the pericardial sac, a "flattened heart" sign, and retroperitoneal hemorrhage. Medicolegal autopsy revealed two abdominal stab wounds near the xiphoid process that had cut the apical pericardium and adjacent diaphragm and liver. Examination of the open thorax confirmed that the pericardial sac was distended with air. The wound extended to the abdominal aorta, causing retroperitoneal hemorrhage. PMCT images showed that the pneumopericardial volume was 133 mL. We believe that cardiac tamponade occurred resulting from the tension pneumopericardium; however, the effects were mitigated by hypovolemia secondary to the retroperitoneal hemorrhage as well as obstructive shock. Therefore, the cause of death appears to have been low-pressure cardiac tamponade.

RESUMO

OBJECTIVE: The management of renal trauma has been changing in recent years so that nowadays, even in high grades, an initial conservative treatment is advocated. The aim of this work is to review the presentation, initial attitude and evolution of the renal traumas treated in our institution. MATERIAL AND METHODS: Retrospective review of patients with renal trauma treated at our institution in the last 10 years. Epidemiological variables, production mechanism, pediatric trauma index (PTI), treatment and evolution were analyzed. RESULTS: We studied 26 patients, 18 men (69.3%). The most frequent mechanism was the direct hit in 11 patients (42.31%). The most frequently side affected was the right one in 14 patients (53.85%). The grade III traumatism according to American Association for the surgery of Trauma (AAST) was the most repeated, 11 patients (42.31%). Nine patients (44.55%) presented concomitant injuries in other solid organs. In 24 patients (92.30%) the initial treatment was conservative with supportive measures. One patient presented with hemodynamic instability and an urgent intervention was conducted, performing a supraselective embolization with immediate control of the active bleeding. In another patient, a double J catheter was placed due to disruption of the excretory tract. Of the patients treated conservatively initially, only one patient (4.1%) required secondary surgical maneuvers due to a complication. CONCLUSIONS: In patients with renal trauma, non-surgical treatment is safe and effective. In case of hemodynamic instability or complication, interventional radiological techniques have been demonstrated to be safe and effective in the pediatric population.


OBJETIVO: El manejo del traumatismo renal ha ido variando en los últimos años de modo que en la actualidad, incluso en los grados altos, se aboga por un tratamiento inicial conservador. El objetivo de este trabajo es revisar la presentación, actitud inicial y evolución de los traumatismos renales atendidos en nuestra institución. MATERIAL Y METODOS: Revisión retrospectiva de pacientes con traumatismo renal atendidos en los últimos 10 años. Se analizaron las variables epidemiológicas, mecanismo de producción, índice de trauma pediátrico (ITP), tratamiento y evolución. RESULTADOS: Se estudiaron 26 pacientes, 18 varones (69,23%). La causa más frecuente fue el golpe directo en 11 pacientes (42,31%). El lado más frecuentemente afectado fue el derecho en 14 pacientes (53,85%). El traumatismo grado III según la American Association for the Surgery of Trauma (AAST) fue el más común, 11 pacientes (42,31%). Nueve pacientes (44,55%) presentaron lesiones concomitantes en otros órganos sólidos. En 24 pacientes (92,30%) el tratamiento inicial fue conservador con medidas de soporte. Un paciente se presentó con inestabilidad hemodinámica y se intervino de forma urgente realizándose embolización supraselectiva con control inmediato del sangrado activo. En otro paciente se colocó un catéter doble J por disrupción de la vía excretora. De los pacientes tratados de manera conservadora inicialmente solo 1 paciente (4,1%) requirió maniobras quirúrgicas secundarias debido a una complicación. CONCLUSIONES: En pacientes con traumatismo renal el tratamiento no quirúrgico es seguro y eficaz. En caso de inestabilidad hemodinámica o complicación, las técnicas radiológicas intervencionistas han demostrado ser seguras y efectivas en la edad pediátrica.

RESUMO

PURPOSE: Nonoperative management (NOM) of gunshot liver injuries (GLI) is infrequently practiced. The aim of this study was to assess the safety of selective NOM of GLI. METHODS: A prospective, protocol-driven study, which included patients with GLI admitted to a level 1 trauma center, was conducted over a 52-month period. Stable patients without peritonism or sustained hypotension with right-sided thoracoabdominal (RTA) and right upper quadrant (RUQ), penetrating wounds with or without localized RUQ tenderness, underwent contrasted abdominal CT scan to determine the trajectory and organ injury. Patients with established liver and/or kidney injuries, without the evidence of hollow viscus injury, were observed with serial clinical examinations. Outcome parameters included the need for delayed laparotomy, complications, the length of hospital stay and survival. RESULTS: During the study period, 54 (28.3%) patients of a cohort of 191 patients with GLI were selected for NOM of hemodynamic stability, the absence of peritonism and CT imaging. The average Revised Trauma Score (RTS) and Injury Severity Score (ISS) were 7.841 and 25 (range 4-50), respectively. 21 (39%) patients had simple (Grades I and II) and 33 (61%) patients sustained complex (Grades III to V) liver injuries. Accompanying injuries included 12 (22.2%) kidney, 43 (79.6%) diaphragm, 20 (37.0%) pulmonary contusion, 38 (70.4%) hemothoraces, and 24 (44.4%) rib fractures. Three patients required delayed laparotomy resulting in an overall success of NOM of 94.4%. Complications included: liver abscess (1), biliary fistula (5), intrahepatic A-V fistula (1) and hospital-acquired pneumonia (3). The overall median hospital stay was 6 (IQR 4-11) days, with no deaths. CONCLUSION: The NOM of carefully selected patients with GLI is safe and associated with minimal morbidity.

RESUMO

A 26-year-old man presented following blunt abdominal trauma to a regional major trauma centre for emergency embolisation of a retroperitoneal bleed from a presumed renal laceration. Imaging had also revealed a large right suprarenal mass. Embolisation resulted in a hypertensive crisis raising the suspicion of a metabolically active adrenal tumour. The course was further complicated by the development of ischaemic bowel requiring emergency laparotomy. Intraoperatively he became haemodynamically unstable from an actively haemorrhaging lesion. Emergency laparotomy and adrenalectomy was performed as a life-saving procedure. Histology confirmed a phaeochromocytoma. The patient made a gradual recovery and was discharged home with no sequelae. Definitive management of phaeochromocytoma is surgical resection which requires prolonged preoperative optimisation with alpha receptor blockers to adequately control blood pressure and prevent hypertensive crises. Parenteral alpha receptor blockers, such as phentolamine, are optimal treatment for intraoperative hypertensive emergencies, yet they are currently not available in the UK.

RESUMO

Patterned bruising of abdominal wall in blunt trauma is called London sign. It indicates that the impacting force is sharp and severe enough to cause visceral injury. Despite its practical significance this sign is seldom described in textbooks and there are no journal articles about it. This communication is intended to draw the attention of pediatric surgeons to this useful clinical sign.

RESUMO

ABSTRACT Objective: to evaluate the epidemiological profile of deaths due to abdominal trauma at the Forensic Medicine Institute of Belo Horizonte, MG - Brazil. Methods: we conducted a retrospective study of the reports of deaths due to abdominal trauma autopsied from 2006 to 2011. Results: we analyzed 1.888 necropsy reports related to abdominal trauma. Penetrating trauma was more common than blunt one and gunshot wounds were more prevalent than stab wounds. Most of the individuals were male, brown-skinned, single and occupationally active. The median age was 34 years. The abdominal organs most injured in the penetrating trauma were the liver and the intestines, and in blunt trauma, the liver and the spleen. Homicide was the most prevalent circumstance of death, followed by traffic accidents, and almost half of the cases were referred to the Forensic Medicine Institute by a health unit. The blood alcohol test was positive in a third of the necropsies where it was performed. Cocaine and marijuana were the most commonly found substances in toxicology studies. Conclusion: in this sample. there was a predominance of penetrating abdominal trauma in young, brown and single men, the liver being the most injured organ.


RESUMO Objetivo: avaliar o perfil epidemiológico dos óbitos por trauma abdominal no Instituto Médico Legal de Belo Horizonte. Métodos: estudo retrospectivo dos laudos de óbitos relacionados a trauma abdominal necropsiados no período de 2006 a 2011. Resultados: foram analisados 1888 laudos necroscópicos de trauma abdominal. O trauma penetrante foi mais comum que o contuso, e o decorrente de projéteis de arma de fogo mais prevalente que o relacionado a armas brancas. A maioria dos indivíduos era do sexo masculino, morena, solteira e ativa do ponto de vista ocupacional. A média etária foi de 34 anos. O homicídio foi a circunstância do óbito mais prevalente, seguido dos acidentes de trânsito, e quase a metade dos casos foi recebida no Instituto Médico Legal proveniente de uma unidade saúde. Os órgãos abdominais mais lesados no trauma penetrante foram o fígado e os intestinos, e no trauma contuso foram o fígado e o baço. A pesquisa de alcoolemia foi positiva em um terço das necropsias onde foi realizada. Cocaína e maconha foram as substâncias mais encontradas nos exames toxicológicos. Conclusão: nesta amostra houve predominância do trauma abdominal penetrante, em homens jovens, morenos e solteiros, sendo o fígado o órgão mais lesado.

RESUMO

BACKGROUND: Guidelines for nonoperative management (NOM) of high-grade pancreatic injuries in children have not been established, and wide practice variability exists. The purpose of this study was to evaluate common clinical strategies across multiple pediatric trauma centers to develop a consensus-based standard clinical pathway. METHODS: A multicenter, retrospective review was conducted of children with high-grade (American Association of Surgeons for Trauma grade III-V) pancreatic injuries treated with NOM between 2010 and 2015. Data were collected on demographics, clinical management, and outcomes. RESULTS: Eighty-six patients were treated at 20 pediatric trauma centers. Median age was 9 years (range, 1-18 years). The majority (73%) of injuries were American Association of Surgeons for Trauma grade III, 24% were grade IV, and 3% were grade V. Median time from injury to presentation was 12 hours and median ISS was 16 (range, 4-66). All patients had computed tomography scan and serum pancreatic enzyme levels at presentation, but serial enzyme level monitoring was variable. Pancreatic enzyme levels did not correlate with injury grade or pseudocyst development. Parenteral nutrition was used in 68% and jejunal feeds in 31%. 3Endoscopic retrograde cholangiopancreatogram was obtained in 25%. An organized peripancreatic fluid collection present for at least 7 days after injury was identified in 59% (42 of 71). Initial management of these included: observation 64%, percutaneous drain 24%, and endoscopic drainage 10% and needle aspiration 2%. Clear liquids were started at a median of 6 days (IQR, 3-13 days) and regular diet at a median of 8 days (IQR 4-20 days). Median hospitalization length was 13 days (IQR, 7-24 days). Injury grade did not account for prolonged time to initiating oral diet or hospital length; indicating that the variability in these outcomes was largely due to different surgeon preferences. CONCLUSION: High-grade pancreatic injuries in children are rare and significant variability exists in NOM strategies, which may affect outcomes and effective resource utilization. A standard clinical pathway is proposed. LEVEL OF EVIDENCE: Therapeutic/care management, level V (case series).

RESUMO

Viscus perforation in the context of blunt-force abdominal trauma is a rarity. Within a sporting context, it is especially rare. However, the increasing physicality observed in rugby union, both in the amateur and professional setting, has resulted in a higher rate of serious injury.

RESUMO

INTRODUCTION: High-tension electricity can cause devastating injuries that may result in abdominal wall loss, visceral damage, and sometimes major threat to life. The visceral organ may be exposed after debridement and require flap cover, but the tensile strength of abdominal wall may be lack even if flap transplanted. METHODS: From April 2007 through May 2015, 5 patients with severe abdominal electrical injury were treated at our hospital. Exploratory laparotomy was performed based on their clinical manifestations and debridement findings of abdominal wall at early stage, and decision regarding technique for reconstruction of abdominal wall was based on an assessment of the location and extent of the defect. Medical records were reviewed for these data. RESULTS: Clinical evaluation and debridement findings of the abdomen revealed 4 patients with suspicious visceral damage. Laparotomy was performed in 4 cases, and revealed obvious lesion in 3 cases, including segmental necrosis of small intestine, partial necrosis of diaphragm, left liver and gastric wall, and greater omentum. Five patients underwent abdominal wall reconstruction using island retrograde latissimus dorsi myocutaneous flap or free/island composite anterolateral thigh myocutaneous flap. All flaps survived, abdominal bulging occurred in 3 cases after follow-up of 12 to 36 months. CONCLUSIONS: The clinical manifestations and wound features of abdomen collectively suggest a possible requirement of laparotomy for severe abdominal electrical burns. Retrograde latissimus dorsi myocutaneous flap or composite anterolateral thigh myocutaneous flap is an effective option for reconstruction of abdominal wall loss, the long-term complication of abdominal bulging, however, remains a significant clinical challenge.

RESUMO

Traumatic abdominal wall hernias due to blunt abdominal trauma in pediatric patients can pose a diagnostic challenge because of spontaneous hernia reduction. Ultrasonography may be superior to computed tomography for this indication in some cases because of the ability to dynamically and repeatedly assess the area of injury. Herniation can be induced or exaggerated via Valsalva maneuvers, which can facilitate its detection during dynamic assessment. We present the case of a 3-year-old boy who sustained blunt abdominal trauma, with a resultant abdominal wall hernia that was diagnosed using point-of-care ultrasound imaging. This hernia was not visualized with computed tomography, and point-of-care ultrasonography expedited admission for operative repair.

RESUMO

Early osteopathic theory and practice, and the work of the medical intuitive Edgar Cayce suggested that the abdominal areas of individuals with epilepsy would manifest "cold spots." The etiology for this phenomenon was thought to be abdominal adhesions caused by inflammation and viscero-somatic reflexes caused by adhesions or injury to visceral or musculoskeletal system structures. Indeed, until that advent of electroencephalography in the 1930s, medical practice regarding epilepsy focused on abdominal neural and visceral structures. Following two hypotheses were formulated to evaluate any abdominal temperature phenomena: (1) an abdominal quadrant division analysis would find one or more quadrants "colder" in the focal-onset epilepsy group (ICD9-CM 345.4 and 345.5) compared to controls. (2) Total abdominal areas of individuals with focal-onset epilepsy wound be colder than a control group. METHODS: Overall, 50 patients with the diagnosis of focal-onset epilepsy were recruited from the office of the Epilepsy Foundation of Florida and 50 control subjects with no history of epilepsy were recruited through advertising to the public. Under controlled room conditions all subjects had infrared thermographic images made and recorded by Med-Hot Model MH-731 FLIR equipment. RESULTS: There were no significant demographic difference between experimental patients and control subjects, though the control group tended to be younger and more often male; however, these were controlled for in all analyses. In the quadrant analysis, there were significant differences in that more epileptic patients had colder left upper abdominal quadrant temperatures than the control group (66.8% versus 44.9%; P = .030). In the total abdominal analysis, however, there were no significant differences. DISCUSSION: The results support the hypothesis that individuals with focal-onset epilepsy have colder abdominal areas. If substantiated in further research, present study results will require further examination of the mechanisms of action for epilepsy, and suggest the need for re-examination of older formulations of abdominal epilepsy, including the place of abdominal injury, inflammation, and adhesions in epileptic pathology. The concept of somato-visceral and viscero-somatic neurological interactions is one of the possible mechanisms underlying the "cold spot" findings and warrants further consideration.

RESUMO

BACKGROUND: As in the rest of the world, the prevalence of obesity in Turkey has been increasing in recent years and has become a major public health issue. Although many trials have been conducted to study the effects of obesity on internal diseases, there are few studies investigating the effects of obesity on prognosis of trauma patients. The present study analyzed the effects of body mass index (BMI) on trauma severity and prognosis in trauma patients. METHODS: This study was prospectively conducted with trauma patients older than 15 years of age who presented at the Dicle University Faculty of Medicine emergency medicine department trauma unit between June 1, 2013 and May 31, 2014. Patients were grouped into high-energy trauma and low-energy trauma groups based on trauma severity. In addition, 4 groups were made according to BMI value (kg/m2). Group I was defined as BMI <25 (normal weight). Group II patients had BMI of 25-29.9 (overweight). Group III had BMI of 30-34.9 (obese), and Group IV was made up of patients with BMI ≥35 (morbidly obese). RESULTS: Comparison of whole patient population for inter-group differences showed significant differences between rate of head injury, thoracic injury, extremity injury, multitrauma, clinic admission rate, and mortality rate (p<0.001). No significant difference was observed between groups in abdominal injury rate (p=0.347). CONCLUSION: Clinic admission rate, length of intensive care unit stay, mortality rate, multitrauma rate, and injury severity score increased in proportion to greater BMI.
