Comparison of the diagnostic accuracy of CT scan with oral and intravenous contrast versus CT scan with intravenous contrast alone in the diagnosis of blunt abdominal trauma / 中华创伤杂志(英文版)

PURPOSE@#Abdominal CT scan using oral and intravenous (IV) contrast is helpful in the diagnosis of intra-abdominal injuries. However, the use of oral and IV contrast delays the process of diagnosis and increases the risk of aspiration. It has also been shown that CT scan with IV contrast alone is as helpful as CT scan with oral and IV contrast and rectal CT scan in detecting abdominal injuries. Therefore, the present study aims to prospectively compare the diagnostic value of CT scan with oral and IV contrast versus CT scan with IV contrast alone in the diagnosis of blunt abdominal trauma (BAT).@*METHODS@#Altogether 123 BAT patients, 60 (48.8%) women and 63 (51.2%) men with the mean age of (40.4 ± 18.7) years who referred to the emergency department of Imam Khomeini Educational and Medical Center in Sari, Iran (a tertiary trauma center in north of Iran) from November 2014 to March 2017 and underwent abdominal CT scans + laparotomy were investigated. Those with penetrating trauma or hemodynamically unstable patients were excluded. The participants were randomly allocated to two groups: abdominal CT scan with oral and IV contrast (n = 63) and CT scan with IV contrast alone (n = 60). No statistically significant difference was found between two groups regarding the hemodynamic parameters, age, gender, injury mechanisms (all p > 0.05). The results of CT scan were compared with that of laparotomy results. The collected data were recorded in SPSS version 22.0 for Windows. Quantitative data were presented as mean and SD.@*RESULTS@#The sensitivity and specificity of CT scan using oral and IV contrast in the diagnosis of BAT were estimated at 96.48 (95% CI: 90.73 - 99.92) and 92.67 (95% CI: 89.65 - 94.88), respectively; while CT scan with IV contrast alone achieved a comparable sensitivity and specificity of 96.6 (95% CI: 87.45 - 99,42 and 92.84 (95% CI: 89.88 - 95.00), respectively.@*CONCLUSION@#CT scan with IV contrast alone can be used to assess visceral injuries in BAT patients with normal hemodynamics to avoid diagnostic delay.

Características clínico quirúrgicas de los pacientes con trauma cerrado de abdomen / Clinical-Surgical Characteristics of Patients with Blunt Abdominal Trauma

Introducción: El traumatismo abdominal cerrado puede provocar lesiones orgánicas graves con hemorragias que demandan un tratamiento quirúrgico emergente y es la principal causa de muertes evitables en todos los grupos de edad. Objetivo: Evaluar las características clínico quirúrgicas de los pacientes con trauma cerrado de abdomen. Métodos: Se realizó un estudio observacional descriptivo y retrospectivo para evaluar el comportamiento del trauma cerrado de abdomen en 81 pacientes atendidos en el Hospital General Provincial Docente "Roberto Rodríguez Fernández" de Morón desde enero del 2014 hasta diciembre de 2019. Resultados: El adulto joven fue el grupo de edad predominante (34,6 por ciento) del sexo masculino (19,8 por ciento), el accidente de tránsito (48,1 por ciento) fue la causa principal. El cuadro hemorrágico (39,5 por ciento) seguidos del cuadro doloroso abdominal (38,3 por ciento) representaron los síntomas clínicos más relevantes. La positividad de los exámenes auxiliares estuvo representada por la ecografía abdominal (74,1 por ciento) seguida de la punción abdominal (9,9 por ciento. Las lesiones hepáticas (27,0 por ciento) seguidas de las esplénicas (19,0 percent) fueron las vísceras macizas más afectadas. El 77,8 por ciento fue intervenido quirúrgicamente y las técnicas quirúrgicas hepáticas fueron las más empleadas para un total de 17 casos (26,9 por ciento). El choque hipovolémico (12,7 por ciento) fue la complicación posoperatoria más encontrada. Se reportó un 12,3 por ciento de fallecidos. Conclusiones: El paciente con trauma cerrado de abdomen debe ser considerado siempre politraumatizado cuyo tratamiento inicial se dirige a la estabilización rápida e identificación de lesiones que amenacen la vida(AU)

Introduction: Blunt abdominal trauma can cause severe organ injury with hemorrhage demanding emergent surgical treatment. It is the leading cause of preventable death among all age groups. Objective: To assess the clinical-surgical characteristics of patients with blunt abdominal trauma. Methods: A descriptive and retrospective observational study was carried out to assess the characteristics of blunt abdominal trauma in 81 patients treated at Roberto Rodríguez Fernández General Provincial Teaching Hospital of Morón from January 2014 to December 2019. Results: Young adults represented the predominant age group (34.6 percent), together with the male sex (19.8 percent). Traffic accident (48.1 percent) was the main cause. Hemorrhagic symptoms (39.5 percent) was the most relevant clinical symptoms, followed by abdominal pain (38.3 percent). Positive results in complementary tests were represented by abdominal ultrasound (74.1 percent), followed by abdominal puncture (9.9 percent). Hepatic lesions (27.0 percent) was the most affected solid viscera, followed by splenic lesions (19.0 percent). 77.8 percent of cases were operated on and hepatic surgical techniques were the most frequently used, accounting for 17 cases (26.9 percent). Hypovolemic shock (12.7 percent) was the most frequent postoperative complication. A death rate of 12.3 percent was reported. Conclusions: The patient with blunt abdominal trauma should always be considered polytraumatized, in which case the initial treatment is aimed at rapid stabilization and identification of life-threatening injuries(AU)

Correlation of rib fracture patterns with abdominal solid organ injury: A retrospective observational cohort study / 中华创伤杂志(英文版)

PURPOSE@#Rib fractures are one of the most common causes of morbidity and mortality and are associated with abdominal solid organ injury (ASOI). The purpose of this study was to investigate the correlation of ASOI with the number, location, and involved segments of rib fracture(s) in blunt chest trauma.@*METHODS@#This retrospective cohort study was conducted on patients with blunt chest trauma over the age of 15 years, who were hospitalized with the diagnosis of rib fractures from July 2015 to September 2020. After ethic committee approval, a retrospective chart review was designed and patients with a diagnosis of rib fractures were selected. Patients who had chest and abdominopelvic CT scan were included in the study and additional data including age, gender, injury severity score, trauma mechanism, number and sides of the fractured ribs (left/right/bilateral), rib fracture segments (upper, middle, lower zone) and results of chest and abdominal spiral CT scan were recorded. The correlation between ASOI and the sides, segments and number of rib fracture(s) was assessed by Pearson's correlation coefficient.@*RESULTS@#Altogether 1056 patients with rib fracture(s) were included. The mean age was (42.76 ± 13.35) years and 85.4% were male. The most common mechanism of trauma was car accident (34.6%). Most fractures occurred in the middle rib zone (60.44%) and the most commonly involved ribs were the 6th and 7th ones (15.7% and 16.4%, respectively). Concurrent abdominal injuries were observed in 103 patients (34.91%) and were significantly associated with middle zone rib fractures.@*CONCLUSION@#There is a significant relationship between middle zone rib fractures and ASOI. Intra-abdominal injuries are not restricted to fractures of the lower ribs and thus should always be kept in mind during management of blunt trauma patients with rib fractures.

Tomografia no trauma abdominal grave: risco justificável? / Computerized Axial Tomography in patients with severe abdominal trauma: is it a justifiable risk?

RESUMO Objetivo: avaliar a evolução de pacientes vítimas de trauma abdominal grave, nos quais o protocolo de transfusão maciça foi acionado, e que foram submetidos à Tomografia Axial Computadorizada (TAC) no Pronto Socorro (PS), com o intuito de verificar o prognóstico do paciente e a eficiência diagnóstica da TAC nesse cenário. Métodos: estudo retrospectivo, longitudinal e observacional, feito em centro de referência para trauma. Foram selecionados 60 pacientes vítimas de trauma abdominal grave que ativaram o protocolo de transfusão maciça, divididos em dois grupos: os submetidos à TAC no PS e os que não foram. Verificou-se a acurácia da TAC, comparou-se o número de óbitos nos dois grupos, o tempo de internamento e os hemocomponentes transfundidos. Resultados: dos 60 pacientes, 66,67% receberam concentrados de hemácias ainda no PS; 33,3% foram submetidos à TAC na admissão, pela melhora hemodinâmica, e 66,7% não realizaram o exame na entrada. O percentual de óbitos foi de 35% em ambos os grupos. A diferença entre as médias do tempo de internamento entre os grupos não foi estatisticamente significativa, assim como a média da quantidade de concentrado de hemácias transfundido. No grupo que fez TAC, 45% não necessitaram de laparotomia exploratória. Conclusão: a TAC pôde ser realizada de maneira rápida em pacientes com instabilidade hemodinâmica na chegada ao PS, não influenciou significativamente a mortalidade e poupou alguns doentes de uma laparotomia exploratória desnecessária.

ABSTRACT Objective: to evaluate the evolution of severe abdominal trauma patients, for whom the massive transfusion protocol was triggered, and who were submitted to Computed Axial Tomography (CAT) in the emergency room (ER), in order to verify the patient's prognosis and the diagnostic efficiency of CAT in this scenario. Methods: retrospective, longitudinal and observational study performed at a referral center for trauma care in Curitiba, Parana, Brazil. We selected 60 severe abdominal trauma patients who had massive transfusion protocol activation and divided them into two groups: patients who underwent CAT at ER and patients who did not. We verified the diagnostic accuracy of CAT-scan examination and compared the number of deaths, hospitalization time, and transfused blood components in both groups. Results: considering the 60 patients, 66.67% received red blood cells at ER; 33.3% underwent CAT on admission due to hemodynamic improvement, and 66.7% did not perform the examination at the entrance. The percentage of deaths was 35% in both groups. Considering the two groups, the difference between the mean lengths of hospital stay was not statistically significant, as well as the difference between the mean numbers of transfused red blood cells. In the group that underwent CAT, 45% did not require exploratory laparotomy. Conclusion: CAT could be rapidly performed in patients with hemodynamic instability on arrival at ER, sparing some patients from an unnecessary exploratory laparotomy and not significantly influencing mortality.

The role of computerized tomography in penetrating abdominal trauma / O papel da tomografia no trauma abdominal penetrante

ABSTRACT 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.

RESUMO Objetivo: avaliar o papel da tomografia computadorizada de abdome no manejo do trauma abdominal penetrante. Métodos: estudo de coorte histórico de pacientes tratados por trauma penetrante em abdome anterior, dorso ou transição tóraco-abdominal que realizaram tomografia computadorizada à admissão. Avaliou-se a localização do ferimento e a presença de achados tomográficos, e o manejo desses pacientes quanto ao tratamento não operatório ou laparotomia. A sensibilidade e especificidade da tomografia computadorizada foram calculadas de acordo com a evolução do tratamento não operatório ou com os achados cirúrgicos. Resultados: foram selecionados 61 pacientes, 31 com trauma em abdome anterior e 30 em dorso ou transição tóraco-abdominal. A taxa de mortalidade foi de 6,5% (n=4), todos no pós-operatório tardio. Onze pacientes com trauma em abdome anterior foram submetidos a tratamento não operatório e 20 à laparotomia. Dos 30 pacientes com trauma em dorso ou transição tóraco-abdominal, 23 realizaram tratamento não operatório e sete foram submetidos à laparotomia. Houve três falhas do tratamento não operatório. Em traumas penetrantes do abdome anterior, a sensibilidade da TC foi de 94,1% e o valor preditivo negativo, 93,3%. Em lesões de dorso ou transição tóraco-abdominal, a sensibilidade foi de 90%, e o valor preditivo negativo foi de 95,5%. Em ambos os grupos, a especificidade e o valor preditivo positivo foram de 100%. Conclusão: a acurácia da tomografia computadorizada foi adequada para direcionar o manejo de pacientes estáveis que puderam ser tratados de forma conservadora, evitando cirurgia mandatória em 34 pacientes e reduzindo a morbimortalidade de laparotomias não terapêuticas.

Basic ultrasound training assessment in the initial abdominal trauma screening / Avaliação de treinamento básico em ultrassom na triagem inicial do trauma abdominal

ABSTRACT Objective: to verify the efficiency and usefulness of basic ultrasound training in trauma (FAST - Focused Assessment with Sonography in Trauma) for emergency physicians in the primary evaluation of abdominal trauma. Methods: a longitudinal and observational study was carried out from 2015 to 2017, with 11 emergency physicians from Hospital Universitário do Oeste do Paraná, submitted to ultrasound training in emergency and trauma (USET® - SBAIT). FAST results started to be collected two months after the course. These were compared with a composite score of complementary exams and surgical findings. Information was stored in a Microsoft Excel program database and submitted to statistical analysis. Results: FAST was performed in 120 patients. In the study, 38.4% of the assessed patients had a shock index ≥0.9. The composite score detected 40 patients with free peritoneal fluid, whereas FAST detected 27 cases. The method sensitivity was 67.5%, specificity was 98.7%, the positive predictive value was 96.4%, the negative predictive value was 85.39% and accuracy was 88%. All those with a positive FAST had a shock index ≥0.9. Fifteen patients with positive FAST and signs of instability were immediately submitted to surgery. Conclusions: the basic training of emergency physicians in FAST showed efficiency and usefulness in abdominal trauma assessment. Due to its low cost and easy implementation, this modality should be considered as a screening strategy for patients with abdominal trauma in health systems.

RESUMO Objetivo: verificar a eficiência e a utilidade do treinamento básico em ultrassom no trauma (Focused Assessment with Sonography in Trauma - FAST) para emergencistas, na avaliação primária do trauma abdominal. Métodos: estudo longitudinal, observacional, realizado durante o período de 2015 a 2017, com 11 emergencistas do Hospital Universitário do Oeste do Paraná, submetidos ao treinamento em ultrassom na emergência e trauma (USET® - SBAIT). Resultados dos FAST começaram ser coletados dois meses após o curso. Estes foram comparados com escore composto de exames complementares e achados cirúrgicos. Informações foram armazenadas em banco de dados do programa Microsoft Excel® e submetidas à análise estatística. Resultados: foram realizados FAST em 120 pacientes. No estudo, 38,4% dos pacientes avaliados apresentavam índice de choque ≥0,9. O escore composto detectou 40 pacientes com líquido livre peritoneal. FAST detectou 27 casos de líquido livre peritoneal. A sensibilidade do método foi de 67,5%, a especificidade de 98,7%, o valor preditivo positivo de 96,4%, o valor preditivo negativo de 85,39% e a acurácia foi de 88%. Todos que tiveram FAST positivo apresentavam índice de choque ≥0,9. Quinze pacientes com FAST positivo e sinais de instabilidade foram conduzidos imediatamente para cirurgia. Conclusões: o treinamento básico de emergencistas em FAST demonstrou eficiência e utilidade na avaliação do trauma abdominal. Por seu baixo custo e facilidade de implantação, esta modalidade deve ser considerada como estratégia de triagem de pacientes com trauma abdominal nos sistemas de saúde.

Ruling out intra-abdominal injuries in blunt trauma patients using clinical criteria and abdominal ultrasound / Exclusão de lesões intra-abdominais em vítimas de trauma fechado através de variáveis clínicas e ultrassom abdominal completo

ABSTRACT Objective: to identify victims of blunt abdominal trauma in which intra-abdominal injuries can be excluded by clinical criteria and by complete abdominal ultrasonography. Methods: retrospective analysis of victims of blunt trauma in which the following clinical variables were analyzed: hemodynamic stability, normal neurologic exam at admission, normal physical exam of the chest at admission, normal abdomen and pelvis physical exam at admission and absence of distracting lesions (Abbreviated Injury Scale >2 at skull, thorax and/or extremities). The ultrasound results were then studied in the group of patients with all clinical variables evaluated. Results: we studied 5536 victims of blunt trauma. Intra-abdominal lesions with AIS>1 were identified in 144 (2.6%); in patients with hemodynamic stability they were present in 86 (2%); in those with hemodynamic stability and normal neurological exam at admission in 50 (1.8%); in patients with hemodynamic stability and normal neurological and chest physical exam at admission, in 39 (1.5%); in those with hemodynamic stability, normal neurological, chest, abdominal and pelvic physical exam at admission, in 12 (0.5%); in patients with hemodynamic stability, normal neurological, chest, abdominal and pelvic physical exam at admission, and absence of distracting lesions, only two (0.1%) had intra-abdominal lesions. Among those with all clinical variables, 693 had normal total abdominal ultrasound, and, within this group, there were no identified intra-abdominal lesions. Conclusion: when all clinical criteria and total abdominal ultrasound are associated, it is possible to identify a group of victims of blunt trauma with low chance of significant intra-abdominal lesions.

RESUMO Objetivo: identificar vítimas de trauma fechado de abdome nas quais as lesões intra-abdominais possam ser excluídas por critérios clínicos e por ultrassonografia abdominal completa. Métodos: análise retrospectiva de vítimas de trauma fechado em que se analisou as seguintes variáveis clínicas: estabilidade hemodinâmica, exame neurológico normal à admissão, exame físico do tórax, do abdome e da pelve normais à admissão e ausência de lesões distrativas (Abbreviated Injury Scale >2 em crânio, tórax e/ou extremidades). Em seguida estudou-se o resultado da ultrassonografia no grupo de pacientes com todas as variáveis clínicas avaliadas. Resultados: estudamos 5536 vítimas de trauma fechado. Lesões intra-abdominais com AIS>1 foram identificadas em 144 (2,6%) casos; em pacientes com estabilidade hemodinâmica, estavam presentes em 86 (2%); naqueles com estabilidade hemodinâmica e exame neurológico normal à admissão em 50 (1,8%); nos casos com estabilidade hemodinâmica, exame neurológico e do tórax normais à admissão em 39 (1,5%); em pacientes com estabilidade hemodinâmica e com exame neurológico, do tórax, do abdome e da pelve normais em 12 (0,5%); naqueles com estabilidade hemodinâmica e com exame neurológico, do tórax, do abdome e da pelve normais e ausência de lesões distrativas, em apenas dois (0,1%) pacientes. Nos pacientes com todas as variáveis clínicas, 693 apresentavam ultrassonografia abdominal completa normal e, neste grupo, não foram identificadas lesões intra-abdominais posteriormente. Conclusão: pela somatória de critérios clínicos e ultrassonografia abdominal completa, é possível identificar um grupo de vítimas de trauma fechado com baixa chance de apresentar lesões intra-abdominais significativas.

Antecedentes: existe una tendencia creciente hacia el tratamiento no operatorio (TNO) en el trauma-tismo cerrado de abdomen (TCA), en pacientes estables hemodinámicamente, sin abdomen agudo peritoneal. No hay consenso sobre: momento de inicio de la dieta, deambulación, proflaxis anttrom-bótica, seguimiento y control, y reinicio de la actividad fisica. Objetivo: describir los resultados del manejo de pacientes con TCA, admitidos en nuestro Servicio de Cirugía. Material y métodos: incluimos pacientes mayores de 15 años internados desde enero de 2011 hasta septembre de 2014, con TCA sometidos a TNO. Se recabaron las variables analizadas de una base de datos electrónica de fichaje prospectivo. Resultados: del total de pacientes 31 TCA, 15 se intervinieron quirúrgicamente al ingreso y 16 pacientes se someteron a TNO. El 73,3% presentó lesiones asociadas extraabdominales. A todos se les realizó ecografa abdominal, donde se encontró líquido libre en el 80% y se identificó lesión de órgano sólido en el 60%. En 11 pacientes se realizó TC confrmando lesión objetivada en la ecografa e iden-tificando 3 no evidenciadas previamente. Se diagnosticaron 5 traumatismos hepáticos, 2 asociados a traumatismo renal; 6 traumatismos esplénicos, 4 renales y un paciente con hemoperitoneo. En 7 pacientes se utlizó tromboproflaxis. El TNO fue exitoso en todos los casos. Tres pacientes presentaron complicaciones. No se registró mortalidad. Conclusiones: los pacientes sometidos a TNO en nuestro hospital fueron tratados exitosamente en todos los casos. No se registró mortalidad en la serie analizada.

Background: there is a growing trend towards non-operative management (NOM) in the blunt abdominal trauma (BAT) in hemodynamically stable patentis without peritoneal acute abdomen. However, there is stll no consensus on: tme of onset of diet, ambulaton, antthrombotic prophylaxis, follow-up, and resumpton of physical activity. Objective: to describe the management of patentis with BAT, admited to the Department of Surgery of our insttuton. Material and methods: we included patentis age 15 and older admited from January 2011 to Sept-ember 2014, with BAT who underwent NOM. The variables analyzed were collected from an electronic database of prospective signing. Resultis: 31 TCA were identifed, 15 were operated on at admission and 16 patentis underwent NOM. 75% were men; mean age of 29 (range 18-58). In 100% abdominal ultrasound was performed, finding free fuid in 80% and identifying organ damage in 60% of the total. In 11 patentis CT scan was perfor-med confrming identifed organ injury on ultrasound and diagnosing three not evidenced previously. We included 5 patentis with liver trauma, 2 associated renal trauma; 6 splenic trauma; 4 kidney trauma and 1 patent with hemoperitoneum. Thromboprophylaxis was used in 7 patentis. NOM was successful in all cases. Three patentis presented complicatons, not associated with trauma. No mortality was recorded. Conclusions: patentis undergoing NOT in our hospital were successfully treated in all cases. There were no complicatons associated with management of the NOT. No mortality was recorded.

Introducción: los traumatismos abdominales constituyen una importante carga en los servicios de urgencia. La ecografía es un método diagnóstico de gran difusión en la actualidad. Objetivo: determinar la utilidad diagnóstica del ultrasonido para predecir la ausencia de injuria en pacientes con traumatismo abdominal. Método: se realizó un estudio observacional y prospectivo, en 68 pacientes, en el Hospital Militar Dr. Luis Díaz Soto, desde enero hasta diciembre 2015, a los cuáles se les realizó ecografía inicial en búsqueda de daño. Se describieron los procederes diagnósticos posteriores al primer ultrasonido y su demora en horas. Resultados: 77,2 por ciento presentó ultrasonido inicial negativo y 14 pacientes necesitaron otros estudios, siendo el ultrasonido evolutivo el de mayor indicación después de 6 horas del primer estudio. Solo dos pacientes presentaron evidencia de daño abdominal para una sensibilidad de la ecografía del 88 por ciento, especificidad 100 por ciento, valor predictivo negativo 96,2 por ciento e índice de eficacia 97 por ciento. Conclusiones: la combinación de hallazgos negativos en un estudio ecográfico inicial y la evolución clínica favorable durante un período de observación de 12 - 24 horas virtualmente excluye injuria abdominal por trauma(AU)

Introduction: The abdominal trauma is an important problem in emergency services and the ultrasound is a widely used diagnostic method nowadays. Objective: To establish the diagnostic usefulness of ultrasound scan to predict absence of injury in patients with abdominal trauma. Method: Prospective and observational research study was made in 68 patients in Dr. Luis Diaz Soto military hospital from January to December 2015. An initial ultrasound was performed on these patients for injure location. The secondary diagnostic exams after the first ultrasound scan and how long they lasted were described. Results: In the group, 77.2 percent of the patients showed negative results in the initial ultrasound exam whereas 14 patients needed another diagnostic procedure. The evolutionary ultrasound was the one providing more indications after 6 hours of the first exam. Only two patients showed evidence of abdominal injury for a sensitivity index of 88 percent, 100 percent specificity, 96.2 percent negative predictive value and 97 percent effectiveness Conclusions : The combination of negative findings in the initial ultrasound and the favorable clinical progress during 12 to 24 hours virtually discard the existence of abdominal injure from trauma(AU)

Hernia diafragmática traumática en un niño / Diaphragmatic traumatic hernia in the little boy

La hernia diafragmática traumática es una afección poco frecuente sobre todo en edades pediátricas. El objetivo de este trabajo es reportar un caso de hernia diafragmática secundaria a un trauma toracoabdominal cerrado. Se presenta el caso de un paciente de 12 años, masculino ingresado en el Servicio de Cirugía Pediátrica de la Provincia de Santiago de Cuba, por haber sufrido un accidente en el hogar (caída de una pared de ladrillos sobre su cuerpo), que produjo traumatismos a nivel craneal, torácico y lumbar. Los estudios radiológicos confirmaron el diagnóstico de hernia diafragmática traumática izquierda. En el acto quirúrgico se comprueba defecto del diafragma izquierdo de aproximadamente 15 cm, con hernia de estómago, bazo y colon. Se realizó reducción y frenorrafia con puntos de colchonero usando poliéster 0, más pleurostomía mínima baja izquierda. El paciente evolucionó satisfactoriamente y egresó a los 10 días para seguimiento en la consulta externa durante 6 meses hasta el alta definitiva(AU)

Traumatic diaphragmatic hernia is a rare illness at pediatric ages. The objective of this paper was to report a case of diaphragmatic hernia secondary to closed thoracoabdominal trauma. This patient is a 12 years-old boy admitted to the pediatric surgery service of Santiago de Cuba province because of an accident at home (a brick wall fell down upon his body) that caused him cranial, thoracic and lumbar traumas. The radiological studies confirmed the diagnosis of traumatic diaphragmatic hernia on the left side. During the surgical act, there was observed an almost 15cm left diaphragm defect with hernias in stomach, spleen and colon. Reduction and phrenorraphy were performed using mattress sewing stitch type, polyester 0 plus left low minimal pleurostomy. The progression of the patient was satisfactory and was discharged from hospital ten days after surgery to be followed up in the outpatient service for 6 months until his complete recovery(AU)

Multidetector CT Findings of Bowel Transection in Blunt Abdominal Trauma

OBJECTIVE: Though a number of CT findings of bowel and mesenteric injuries in blunt abdominal trauma are described in literature, no studies on the specific CT signs of a transected bowel have been published. In the present study we describe the incidence and new CT signs of bowel transection in blunt abdominal trauma. MATERIALS AND METHODS: We investigated the incidence of bowel transection in 513 patients admitted for blunt abdominal trauma who underwent multidetector CT (MDCT). The MDCT findings of 8 patients with a surgically proven complete bowel transection were assessed retrospectively. We report novel CT signs that are unique for transection, such as complete cutoff sign (transection of bowel loop), Janus sign (abnormal dual bowel wall enhancement, both increased and decreased), and fecal spillage. RESULTS: The incidence of bowel transection in blunt abdominal trauma was 1.56%. In eight cases of bowel transection, percentage of CT signs unique for bowel transection were as follows: complete cutoff in 8 (100%), Janus sign in 6 (100%, excluding duodenal injury), and fecal spillage in 2 (25%). The combination of complete cutoff and Janus sign were highly specific findings in patients with bowel transection. CONCLUSION: Complete cut off and Janus sign are the unique CT findings to help detect bowel transection in blunt abdominal trauma and recognition of these findings enables an accurate and prompt diagnosis for emergency laparotomy leading to reduced mortality and morbidity.

Trauma no reciente en abdomen cerrado / Non-recent abdominal closed trauma

Entre las urgencias atendidas por traumatismos diversos, en el Centro Diagnóstico Integral Dr Salvador Allende, en Caracas, Venezuela, se destacó el caso que se expone, luego de estar 60 días procurando atención médica en diferentes instituciones hospitalarias, sin recibir credibilidad la joven enferma. Se expone la historia de la paciente, y sus eventualidades con los hallazgos laparotómicos. Se corrobora la necesidad laparotómica con la presunción inicial por juicio clínico y se logra el consentimiento informado familiar. Como refuerzo de la praxis se efectuó el procedimiento omentun mayus, que combate la sepsis futura y garantiza la integridad subfrénica. Este caso trauma visceral circunscrito al lóbulo derecho del hígado favorece, por su carácter y modo, la enseñanza a educandos y especialistas, en caso de afrontar traumas no recientes(AU)

Her history is exposed and its eventualities with the laparotomy findings. Laparotomy need is corroborated according an early clinical criterion and the achievement of the family informed consent. As a praxis effort, the omentum mayus procedure was carried out preventing the future sepsis and to guarantee the subfrenic integrity. Present case —visceral trauma restricted to liver right lobule, due to its character and mode, favors the teaching to students and specialists when they to face non-recent traumata(AU)

Earthquake-related Crush Injury versus Non-Earthquake Injury in Abdominal Trauma Patients on Emergency Multidetector Computed Tomography: A Comparative Study

The aim of this study was to investigate features of abdominal earthquake-related crush traumas in comparison with non-earthquake injury. A cross sectional survey was conducted with 51 survivors with abdominal crush injury in the 2008 Sichuan earthquake, and 41 with abdominal non-earthquake injury, undergoing non-enhanced computed tomography (CT) scans, serving as earthquake trauma and control group, respectively. Data were analyzed between groups focusing on CT appearance. We found that injury of abdominal-wall soft tissue and fractures of lumbar vertebrae were more common in earthquake trauma group than in control group (28 vs 13 victims, and 24 vs 9, respectively; all P < 0.05); and fractures were predominantly in transverse process of 1-2 vertebrae among L1-3 vertebrae. Retroperitoneal injury in the kidney occurred more frequently in earthquake trauma group than in control group (29 vs 14 victims, P < 0.05). Abdominal injury in combination with thoracic and pelvic injury occurred more frequently in earthquake trauma group than in control group (43 vs 29 victims, P < 0.05). In conclusion, abdominal earthquake-related crush injury might be characteristic of high incidence in injury of abdominal-wall soft tissue, fractures of lumbar vertebrae in transverse process of 1-2 vertebrae among L1-3 vertebrae, retroperitoneal injury in the kidney, and in combination with injury in the thorax and pelvis.

Management of patients with blunt abdominal trauma

To evaluate limitations of diagnostic peritoneal lavage and ultrasonography in patients with blunt abdominal trauma. The study was conducted in Accident and Emergency Department of Nishtar Hospital, Multan on 100 cases presented with BAT having equivocal abdominal findings during one year i.e. September 2007 to September 2008. It was a prospective comparative study. Main age group involved in accidents and BAT was between 40 to 60 years. Male to female ration was 5:1. Liver was main organ injured in most cases. It was observed that DPL was 100% sensitive and 91.3% specific while USG of abdomen was 88.9% sensitive and 100% specific. DPL is more sensitive while abdominal USG is more specific. Both are complementary to each other. By using these diagnostic modalities we can reduce both morbidity and mortality and also hospital stay

Accurate determination of wound depth with ultrasound and its forensic significance / 法医学杂志

Accurate determination of the wound depth has long been a difficult task in forensic medicine due to lack of technology. Nowadays, the depth of the wound can be accurately determined by using high frequency 2-D ultrasound and Color Doppler Flow Imaging (CDFI). Two typical cases with ultrasonic images were reported to show the importance of ultrasound technology in forensic medicine. The new technology provides scientific evidence of the injury assessment.

role of computed tomography in blunt abdominal trauma

To determine the utility of the computed tomography [CT] scan in blunt abdominal trauma and to compare it with operative findings or clinical outcomes. A retrospective analysis based on existing, diagnostic CT scan reports taken during a 5 year period from 245 consecutive patients with blunt abdominal trauma. Percentages and types of trauma identified were based on CT scan findings. Recorded data included age, sex, type of injuries and scan results. The CT findings were compared and correlated with the operative findings, or clinical follow-up in conservatively managed cases. Of the total of 245 patients, 113 [46%] underwent surgery. One hundred and thirty two [54%] patients were conservatively managed. There were 12 [4.9%] deaths. Hemoperitoneum were detected in 170 patients. All 52 patients with small hemoperitoneum on CT scan were conservatively managed and all 22 patients with large hemoperitoneum required surgical exploration. There were 95 splenic, 63 renal, 48 hepatic and 13 pancreatic injuries. Twenty one patients had bowel injuries. Five patients had vascular injuries. Twenty three patients had multi-organ injuries. Organ injuries were graded using the OIS [Organ Injury Scale] guidelines. In conjunction with close clinical monitoring, CT was reliable in the evaluation of blunt abdominal trauma in a selected group of patients, with overall sensitivity of 97% and specificity of about 95%. Positive predictive value 82% and negative predictive value 100%

Surgical Management of Blunt Abdominal Trauma

To evaluate and compare the usefulness and limitations of diagnostic peritoneal lavage and ultrasonography in patients with blunt abdominal trauma. The study was conducted Nishtar Hospital, Multan on 100 cases presented with BAT having equivocal abdominal findings during one year i.e. March 2005 to February 2006. It was a prospective comparative study. Main age group involved in accidents and BAT was between 40 to 60 years Male to female ration was 5:1 Liver was main organ injured in most cases of BAT. It was observed that DPL was 100% sensitive and 91.3% specific while USG of abdomen was 88.9% sensitive and 100% specific. DPL. is more sensitive while abdominal USG is more specific. Both are complementary to each other

role of diagnostic laparoscopy in management of the patients with blunt abdominal trauma

Abdominal trauma may result in a variety of intra-abdominal injuries, ranging in severity from mild to life threatening. Nowadays, the choice of investigation and management depends primarily on the haemodynamic stability of the patient Ultrasound [U/S], diagnostic protineal lavage [DPL] and Laparoscopy are widely used in the diagnosis of blunt abdominal trauma [BAT]. Historically, exploratory laparotomy was done for the patient clinically suspected to have intra-abdominal organ injury following blunt abdominal trauma. If following initial survey and assessment abdominal signs continue to be equivocal laparoscopy provides the most definitive early evaluation technique. In this study, 60 patients with history of blunt abdominal trauma were included. Diagnostic laparoscopy failed to detect splenic injuries in 2 patents out of the 60 patients studied because of a large clot in the left upper quadrant, 48 patients were exposed to laparotomy. The most common findings in those 48 patients were isolated liver injuries in 20 patients [33.3%] followed by isolated splenic injuries in 6 patients [10%]. DPL and US can be performed for patients with BAT while they are being resuscitated. Conservative treatment in properly selected patients has become the standard. Among 15 patients who were chosen to be treated conservotivelly, twelve patients underwent conservative treatment in this study with a success rate of 80% and three patient needed an exploratory laparotomy due to haemodynamic instability that developed during the follow-up period. Abdominal ultrasonography has proved to be of little value in deciding the possibility of conservative treatment due to inability to detect the grade of solid organ injury. DPL has no role in conservative treatment of blunt abdominal injuries. Early identification of significant infra-abdominal injuries is necessary for the successful management of blunt abdominal trauma because delay in diagnosis can lead to significant morbidity and mortality The rapidly increasing role of diagnostic and therapeutic laparoscopy in current surgical practice prompted us to investigate the potential role this procedure in the assessment and management of stable patients with U/S evidence of solid organ injury [SOIs] after blunt abdominal trama. Laparoscopy decreases the rate of unnecessary laparotomies in abdominal trauma and helps to diagnose injuries of solid organs. Frequent clinical evaluation of the patients' condition, ultrasonograpy and DPL are complementary and important in the diagnosis and management of the patients with abdominal trauma
