RESUMO

INTRODUÇÃO: O manejo dos pacientes vítimas de PAF possui vertentes divergentes a respeito do tratamento cirúrgico, que pode ser realizado de forma imedata ou tardia. Em lesões auto-infligidas, a distância entre a arma e a região acometida é menor, causando consequências estéticas e funcionais mais devastadoras. Aliado ao fato desse tipo de trauma criar uma ferida suja devido à comunicação com a cavidade oral e seios paranasais, o manejo das lesões representam um desafio mesmo à cirurgiões experientes. OBJETIVO: Estre trabalho relata o manejo cirúrgico de uma ferida auto-infligida por arma de fogo que resultou em avulsão dos tecidos moles na região maxilofacial. DESCRIÇÃO DO CASO: Paciente do sexo masculino, 35 anos, vítima de projétil de arma de fogo auto-infligido em região maxilofacial, cursando com extenso ferimento em região de língua e mento. Clinicamente, o paciente não apresentava sinais de fratura em ossos da face. Ambos os ferimentos apresentavam secreção purulenta e o paciente manifestava disfonia devido a grande destruição tecidual. CONSIDERAÇÕES FINAIS: O tratamento de ferimentos por arma de fogo não só é um grande desafio para o cirurgião, como para toda a equipe multidisciplinar requerida para tais casos, visto que não há protocolos bem definidos para o tratamento dessas lesões(AU)

INTRODUCTION: The management of patients who are victims of FAP has divergent aspects regarding surgical treatment, which can be performed immediately or late. In self-inflicted injuries, the distance between the weapon and the affected region is smaller, causing more devastating aesthetic and functional consequences. Allied to the fact that this type of trauma creates a dirty wound due to the communication with the oral cavity and paranasal sinuses, the management of injuries represents a challenge even for experienced surgeons. OBJECTIVE: This paper reports the surgical management of a self-inflicted gunshot wound that resulted in soft tissue avulsion in the maxillofacial region. CASE DESCRIPTION: Male patient, 35 years old, victim of a self-inflicted firearm projectile in the maxillofacial region, coursing with extensive injury in the region of the tongue and chin. Clinically, the patient did not show signs of facial bone fractures. Both wounds had purulent secretion and the patient had dysphonia due to extensive tissue destruction. FINAL CONSIDERATIONS: The treatment of gunshot wounds is not only a great challenge for the surgeon, but also for the entire multidisciplinary team required for such cases, since there are no well-defined protocols for the treatment of these injuries(AU)

RESUMO

RESUMEN Andrés Avelino Cáceres (1836-1923) fue un destacado político y militar peruano que ocupó la presidencia en dos periodos y lideró al ejército peruano durante la Guerra del Pacífico, por lo que es considerado un héroe nacional. Al inicio de su carrera militar, durante el sitio a la ciudad de Arequipa en 1858, sufrió una lesión ocular cuya cicatriz se observa en las fotografías que se le tomaron posteriormente a lo largo de su vida, lo que hizo que fuera apodado "El Tuerto" aunque al parecer su agudeza visual estuvo indemne. En este trabajo describiremos las circunstancias en las que se produjo la lesión oftálmica de Andrés Avelino Cáceres, las secuelas que pudo tener este traumatismo oftálmico y el tratamiento médico que pudo haber recibido, en base al propio relato del héroe y a las imágenes suyas que se conservan.

ABSTRACT Andrés Avelino Cáceres (1836-1923) was a prominent Peruvian politician and military man who held the presidency for two terms and led the Peruvian army during the Pacific War, for which he is considered a national hero. At the beginning of his military career, during the siege of the city of Arequipa in 1856, he suffered an eye injury whose scar can be seen in the photographs that were taken of him later throughout his life, which led to him being nicknamed "El Tuerto". We will describe the circumstances in which the ophthalmic injury of Andrés Avelino Cáceres occurred, the consequences that this ophthalmic trauma could have had and the treatment he could have received, based on the hero's own story and the images of him that are preserved.

RESUMO

ABSTRACT Objective: Establish the frequency of incidences, management, and description of the relationship between thoracic and abdominal trauma and spinal injury. Methods: Observational, retrospective study of quantitative analysis carried out through the analysis of medical records of patients who presented spinal fractures and associated thoracoabdominal injuries. The participants were treated at a reference hospital in trauma care in Curitiba-PR from 2019 to 2021. The data were from patients with spine fractures referring to gender, age, trauma mechanism, fracture classification, associated injuries, Frankel neurological scale, and proposed treatment. Results: There was a predominance of male patients (84.5%) and young, with a mean age of 37.3 years, victims of car accidents. The main vertebrae affected were the lumbar spine (36.8%) and thoracic spine (36.2%). The most prevalent associated injuries were extra vertebral and cervical spine fractures. The most observed thoracic injuries were hemothorax, chest contusion, and fracture of multiple costal arches, while the most observed abdominal injuries were kidney injury, hemoperitoneum/abdominal hematoma, and liver injury. Of the total patients analyzed, 68% had fractures with associated thoracoabdominal injuries. Conclusion: Abdominal and thoracic injuries are frequently associated with spine fractures, with an association of 14.6% and 53.4%, respectively. The production of knowledge on the subject contributes to creating action plans to optimize the management and reduce the morbidity and mortality of these cases.

RESUMO

Os ferimentos por arma de fogo (FAF) são um grande problema de saúde pública. Na face, a mandíbula é o local de maior incidência, sendo a região de corpo mandibular a mais atingida e as lesões aos tecidos moles frequentemente a ela associadas. Em alguns casos, tais ferimentos apresentam-se de difícil resolução, sobretudo, em casos de fraturas cominutivas e lesões de tecidos moles com alta complexidade. Isso torna o atendimento desses pacientes um desafio para cirurgiões buco-maxilo-faciais. Desta forma, o objetivo deste artigo é relatar um caso de FAF em terço inferior da face, com comprometimento de tecidos moles e mandíbula, pela equipe de Cirurgia e Traumatologia Bucomaxilofacial do Hospital Geral do Estado - Bahia. Paciente de 28 anos de idade, sexo feminino, vítima de FAF em terço inferior da face, por disparo acidental de espingarda. Ao exame clínico, pode-se observar ferimento perfuro-contuso em região de mandíbula e fratura cominutiva de corpo e ângulo mandibular à direita. A paciente foi submetida à cirurgia para remoção de fragmentos ósseos/corpos estranhos, fixação dos cotos com placa de reconstrução 2.4mm e sutura dos planos, em mesmo tempo cirúrgico, reestabelecendo a função da mandíbula. Portanto, devido à fisiopatologia variável dos FAF na mandíbula, não se indica um único padrão de tratamento para as fraturas cominutivas. Além disso, é indispensável o emprego de protocolos de limpeza cirúrgica imediata e antibioticoterapia nos casos com alto grau de cominuição, bem como, sugere-se realizar o tratamento definitivo o mais breve possível(AU)

Firearm injuries (FIs) are a major public health problem. On the face, the mandible is the place with the highest incidence of this trauma, with the mandibular body region being the most affected and the lesions to the soft tissues frequently associated with it. In some cases, such injuries are difficult to resolve, especially in cases of comminuted fractures and soft tissue injuries with high complexity. This makes the care of these patients a challenge for oral and maxillofacial surgeons. Thus, the objective of this article is to report a case of care for a FAF victim in the lower third of the face, with soft tissue and mandible involvement, by the Maxillofacial Surgery and Traumatology team at the Hospital Geral do Estado - Bahia. 28-year-old female patient, victim of FAF in the lower third of the face, due to acidental shotgun firing. On clinical examination, a perforated-blunt wound can be seen in the mandible region and comminuted fracture of the body and angle of the mandible on the right. The patient underwent surgery to remove bone fragments / foreign bodies, fix the stumps with a 2.4 mm reconstruction plate and suture the planes, at the same surgical time, reestablishing the function of the mandible. Therefore, due to the variable pathophysiology of FAF in the mandible, a single treatment pattern is not indicated for comminuted fractures. In addition, it is essential to use immediate surgical cleaning protocols and antibiotic therapy in cases with a high degree of comminution, as well as, it is suggested to carry out the definitive treatment as soon as possible(AU)

RESUMO

Abstract Introduction: In high-volume trauma centers, especially in developing countries, penetrating cardiac box injuries are frequent. Although many aspects of penetrating chest injuries have been well established, video-assisted thoracoscopy is still finding its place in cardiac box trauma and algorithmic approaches are still lacking. The purpose of this manuscript is to provide a streamlined recommendation for penetrating cardiac box injury in stable patients. Methods: Literature review was carried out using PubMed/MEDLINE and Google Scholar databases to identify articles describing the characteristics and concepts of penetrating cardiac box trauma, including the characteristics of tamponade, cardiac ultrasound, indications and techniques of pericardial windows and, especially, the role of video-assisted thoracoscopy in stable patients. Results: Penetrating cardiac box injuries, whether by stab or gunshot wounds, require rapid surgical consultation. Unstable patients require immediate open surgery, however, determining which stable patients should be taken to thoracoscopic surgery is still controversial. Here, the classification of penetrating cardiac box injury used in Colombia is detailed, as well as the algorithmic approach to these types of trauma. Conclusion: Although open surgery is mandatory in unstable patients with penetrating cardiac box injuries, a more conservative and minimally invasive approach may be undertaken in stable patients. As rapid decision-making is critical in the trauma bay, surgeons working in high-volume trauma centers should expose themselves to thoracoscopy and always consider this possibility in the setting of penetrating cardiac box injuries in stable patients, always in the context of an experienced trauma team.

RESUMO

Rectal trauma is uncommon, but it is usually associated with injuries in adjacent pelvic or abdominal organs. Recent studies have changed the paradigm behind military rectal trauma management, showing better morbidity and mortality. However, damage control techniques in rectal trauma remain controversial. This article aims to present an algorithm for the treatment of rectal trauma in a patient with hemodynamic instability, according to damage control surgery principles. We propose to manage intraperitoneal rectal injuries in the same way as colon injuries. The treatment of extraperitoneal rectum injuries will depend on the percentage of the circumference involved. For injuries involving more than 25% of the circumference, a colostomy is indicated. While injuries involving less than 25% of the circumference can be managed through a conservative approach or primary repair. In rectal trauma, knowing when to do or not to do it makes the difference.

El trauma de recto es poco frecuente, pero generalmente se asocia a lesiones de órganos adyacentes en la región pélvica y abdominal. Estudios recientes han cambiado los paradigmas del manejo tradicional derivados del trauma militar, mostrando mejores resultados en la morbilidad y mortalidad. Sin embargo, las técnicas de control de daños en el trauma rectal aún son controvertidas. El objetivo de este articulo es proponer el algoritmo de manejo del paciente con trauma rectal e inestabilidad hemodinámica, según los principios de la cirugía de control de daños. Se propone que las lesiones del recto en su porción intraperitoneal sean manejadas de la misma manera que las lesiones del colon. Mientras que el manejo de las lesiones extraperitoneales del recto dependerá del compromiso de la circunferencia rectal. Si es mayor del 25% se recomienda realizar una colostomía. Si es menor, se propone optar por el manejo conservador o el reparo primario. Saber que hacer o que no hacer en el trauma de recto marca la diferencia.

RESUMO

Abstract Introduction: Diaphragmatic injuries are a common finding in patients with penetrating thoracoabdominal trauma. Their diagnosis requires exploration through open or laparoscopic surgery. However, multislice computed tomography (MSCT) emerges as a useful noninvasive tool for this purpose. Objective: To determine the diagnostic performance of MSCT for detecting diaphragmatic injuries in hemodynamically stable patients with penetrating thoracoabdominal trauma. Materials and methods: Prospective study conducted on 119 patients treated at the Hospital Universitario del Valle, Cali, Colombia, between March 2012 and June 2015. In order to evaluate the diagnostic performance of MSCT, the results obtained through this test were compared with those reported in the reference test (open surgery). Two readings of the imaging studies were performed by 2 radiologists. Intra- and interobserver agreement on the MSCT readings were analyzed using the Fleiss' Kappa coefficient. Results: MSCT had sensitivity and specificity of 94.4% and 46.8%, respectively. Its positive (PPV) and negative (NPV) predictive values were 44.7% and 94.8%, respectively. The positive likelihood ratio (LR+) was 1.7765, and the negative likelihood ratio (LR-) was 0.1186. Regarding interobserver agreement, Fleiss' Kappa coefficient between the first reading of both radiologists was 0.4425. Conclusions: MSCT specificity for diagnosing diaphragmatic injuries found in this study differs considerably from that reported in the literature. Considering the sensitivity, PPV and LR- values obtained in the present study, MSCT could be an important tool for the management of these patients since conservative treatment may be used in patients whose diaphragmatic injuries are not detected with this type of scan.

Resumen Introducción. Las heridas diafragmáticas son un hallazgo común en pacientes con trauma toracoabdominal penetrante. Su diagnóstico requiere exploración mediante cirugía abierta o laparoscópica. Sin embargo, la tomografía computarizada multidetector (TCMD) surge como una herramienta no invasiva útil para este propósito. Objetivo. Determinar el rendimiento diagnóstico de la TCMD en la identificación de heridas diafragmáticas en pacientes con trauma toracoabdominal penetrante hemodinámicamente estables. Materiales y métodos. Estudio prospectivo realizado en 119 pacientes atendidos en el Hospital Universitario del Valle, Cali, Colombia, entre marzo de 2012 y junio de 2015. Para evaluar el rendimiento diagnóstico de la TCMD, los resultados obtenidos mediante esta prueba fueron comparados con los reportados por el test de referencia (cirugía abierta). Se realizaron 2 lecturas de los estudios de imagen por 2 radiólogos. La concordancia intra e interobservador respecto a la lectura de las TCMD se analizó mediante el coeficiente Kappa de Fleiss. Resultados. La TCDM tuvo una sensibilidad y especificidad de 94.4% y 46.8%, respectivamente. Sus valores predictivos positivo (VPP) y negativo (VPN) fueron 44.7% y 94.8%, respectivamente. La razón de verosimilitud positiva (LR+) fue 1.7765, y la razón de verisimilitud negativa (LR-), 0.1186. Respecto a la concordancia interobservador, el coeficiente Kappa de Fleiss entre la primera lectura de ambos radiólogos fue de 0.4425. Conclusiones. La especificidad de la TCMD para el diagnóstico de heridas diafragmáticas encontrada en el presente estudio difiere considerablemente de lo reportado en la literatura. Teniendo en cuenta la sensibilidad, el VPN y la LR- obtenidos en el presente estudio, la TCMD podría constituir una herramienta importante en el manejo de estos pacientes, ya que en aquellos en los que no se detecte herida diafragmática mediante este tipo de tomografía podría considerarse un manejo conservador.

RESUMO

As armas de fogo são instrumentos letais que estão relacionados a uma grande quantia de homicídios no Brasil, além de traumas e violências. Assim, o atendimento pré-hospitalar e hospitalar é importante na tentativa de diminuir os índices de mortalidade por causas externas. Esta revisão de literatura teve como objetivo demonstrar as formas protocoladas de atendimento atuais a um paciente com trauma por projétil de arma de fogo (AU).

Firearms are lethal instruments that are related to a large amount of homicides in Brazil, as well as traumas and violence. Thus, pre-hospital and hospital care is important in the attempt to reduce mortality rates due to external causes. This literature review aimed to demonstrate the current protocol forms of care for a patient with gunshot wound. (AU)

RESUMO

Resumen: Las llamadas armas no letales son parte del arsenal de las fuerzas de seguridad y están diseñadas para reprimir disturbios penitenciarios y protestas masivas en espacios públicos. La falsa idea de que la posibilidad de que causen lesiones graves y muerte es baja ha ayudado a extender su uso. Se presentan dos casos de muertes violentas causadas por impactos de los llamados proyectiles no letales utilizados por el personal policial encargado de la seguridad en los establecimientos de reclusión en nuestro país. Se cuestiona la seguridad de este tipo de armas y municiones en situaciones de estrés, en que no se puede garantizar una correcta utilización (distancia mínima y sector corporal de impacto). Se recomienda erradicar la denominación de "armas no letales" y sustituirla por otra más moderna y ajustada a la realidad como "armas menos letales".

Summary: The so-called non-lethal weapons are part of the weapon arsenal available to the police forces, and they were designed to control prison riots and massive protests in public spaces. The false idea they have low chances of causing severe lesions or death has contributed to their being more widely used. The study presents two cases of violent deaths caused by the impact of the so called non-lethal projectiles used by policemen in charge of security in the prisons of our country. Safety of this kind of weapons under stressful situations is questioned, since there is no guarantee for them to be used properly (minimum distance and impact body area). A recommendation is made to eradicate using the label "non-lethal weapons" and substitute it for a more modern and appropriate one, such as "less lethal weapons".

Resumo: As chamadas armas não letais fazem parte do arsenal das forças de segurança e têm como objetivo suprimir motins em prisões e protestos em massa em espaços públicos. O equívoco de que a possiblidade de causar de ferimentos graves e morte é baixa ajudou a espalhar seu uso. Há dois casos de mortes violentas causadas por impactos dos chamados projéteis não letais utilizados pelos policiais encarregados da segurança dos centros de detenção em nosso país. A segurança deste tipo de armas e munições é questionada em situações de estresse, em que não se pode garantir o uso correto (distância mínima e setor corporal de impacto). Recomenda-se erradicar o nome "armas não letais" e substituí-lo por um mais moderno e realista, como "armas menos letais".

RESUMO

Objective To investigate the incidence of infection in patients with gunshot-related fractures, and to correlate this finding with the occurrence of surgical debridement in the emergency room. Methods A retrospective, observational, descriptive study that included all cases of fractures caused by firearms between January 2010 and December 2014; 245 fractures in 223 patients were included. Results There was surgical-site infection in 8.5% of the fractures, and the mean number of debridements required to control the infectious process was of 1.273 ± 0.608. A correlation was identified between the surgical treatment chosen and the affected body segment ( p < 0.001). The surgical treatment in the emergency room had a correlation with the occurrence of infection ( p < 0.001; Chi-squared test). Conclusion Patients with gunshot injuries treated non-operatively presented less severe and stable lesions; thus, the incidence of complications in this group was found to be lower. On the other hand, those patients with complex lesions underwent debridement and external fixation. Therefore, a greater number of infectious complications in patients submitted to external fixation was found, as expected.

Resumo Objetivo Investigar a incidência de infecção em pacientes com fraturas por arma de fogo, e correlacionar esse achado com a ocorrência de desbridamento cirúrgico na sala de emergência. Métodos Estudo retrospectivo, observacional e descritivo, que incluiu todos os casos de fraturas causadas por armas de fogo entre janeiro de 2010 e dezembro de 2014; foram incluídas 245 fraturas em 223 pacientes. Resultados Houve infecção do local cirúrgico em 8,5% das fraturas, e a média de desbridamentos necessários para controlar o processo infeccioso foi de 1,273 ± 0,608. Foi identificada correlação entre o tratamento cirúrgico escolhido e o segmento corporal afetado (p< 0,001). O tratamento cirúrgico na sala de emergência teve correlação com a ocorrência de infecção (p< 0,001; teste do qui-quadrado). Conclusão Pacientes com ferimentos à bala tratados de forma não operatória apresentaram lesões menos graves e estáveis; portanto, a incidência de complicações nesse grupo foi menor. Por outro lado, os pacientes com lesões complexas foram aqueles submetidos a desbridamento e fixação externa. Portanto, como esperado, foi encontrado um maior número de complicações infecciosas em pacientes submetidos à fixação externa.

RESUMO

ABSTRACT Foreign bodies in the paranasal sinuses after critical accidents are rare occurrences that have sporadically been reported worldwide. Firearm projectiles, daggers, knives, glass fragments, stones, teeth, and wood can get lodged in the soft and hard tissues of the face. The management and prognosis in these cases depend on the composition and location of the foreign body as well as on the presence or absence of infection. Although there are reports involving the soft tissues of the face, the ethmoid, sphenoid, frontal, and maxillary sinuses are the most frequently involved sites. The main manifestation of this condition is sinusitis arising from infection and/or inflammation caused by the foreign body, which is a contaminated object. We report a case of removal of a firearm projectile located in the maxillary sinus of a 34-year-old patient under local anesthesia.

RESUMO Corpos estranhos nos seios paranasais são ocorrências raras que têm sido esporadicamente relatadas na literatura em todo o mundo. Projéteis de arma de fogo, punhais, facas, fragmentos de vidro, pedras, dentes e madeira podem ficar alojados nos tecidos moles e duros do rosto. O manejo e o prognóstico nesses casos dependem da composição e localização do corpo estranho, bem como da presença ou ausência de infecção. Embora haja relatos envolvendo os tecidos moles da face, os seios etmoidal, esfenoidal, frontal e maxilar são os locais mais frequentemente envolvidos. A principal manifestação dessa condição é sinusite decorrente de infecção e / ou inflamação causada pelo corpo estranho, que é um objeto contaminado. Relatamos um caso de remoção de um projétil de arma de fogo localizado no seio maxilar de um paciente de 34 anos de idade, sob anestesia local.

RESUMO

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

RESUMO O tratamento não operatório de ferimentos abdominais causados por projéteis de armas de fogo ocorridos na região anterior do abdome permanece controverso. Este artigo apresenta revisão narrativa da literatura após a seleção de estudos levantados em bancos de dados eletrônicos (PubMed, Cochrane Library e Lilacs), com a intenção de avaliar os parâmetros clínicos e exames de diagnóstico que deverão fazer parte do da abordagem conservadora seletiva dessas lesões. Avaliando os estudos selecionados, foi verificado que conduta não operatória seletiva pode ser empregada de forma eficaz e segura, quando realizada por equipe interdisciplinar treinada, atuando em Centros de Traumas adequados para a realização deste tipo de atendimento. O tratamento não operatório seletivo está associado à diminuição de laparotomias negativas e não terapêuticas, reduzindo a incidência de complicações, além de colaborar para a diminuição dos custos hospitalares.

RESUMO

Abstract Penetrating heart injuries present high mortality rates. Increasing rates of urban violence have contributed to a significant rise in the number of heart injuries by firearm projectiles. Such injuries are associated with the highest mortality rates among penetrating cardiac injuries and may involve one or more cardiac chambers. We present the case of a police officer who, in an approach to five robbers, suffered a transfixed cardiac injury by firearm with the projectile having been lodged inside the right ventricle. This patient was successfully operated, 65 days after the injury, at our institution.

RESUMO

Bullet embolization of the arterial or venous systems is a rare complication of penetrating gunshot injuries. A 29-year-old man presented at the emergency department with a gunshot wound to the left arm, which had transfixed the arm and entered the thorax, with no exit wound. Initial radiographies showed a projectile in the upper left thigh. Contrast-enhanced tomography showed a pseudo-aneurysm of the descending thoracic aorta and the bullet inside the proximal left superficial femoral artery. Physical examination found diminished left pedal pulses, and the patient complained of left toe numbness. Endovascular thoracic aortic pseudoaneurysm repair was performed, sealing the descending aortic orifice with an endograft, and thromboembolectomy/bullet retrieval was carried out via a left femoral incision, both successfully. Considering that diagnosis of missile emboli depends on a high degree of suspicion, physicians who manage gunshot wound patients must be acutely aware of the possibility of intravascular bullet embolism.

A embolia balística pelo sistema arterial ou venoso é uma complicação rara de ferimentos penetrantes por arma de fogo. Um homem de 29 anos se apresentou na emergência com um ferimento por arma de fogo no braço esquerdo, que transfixou o braço e atingiu o tórax, sem ferimento de saída. Radiografias iniciais mostraram o projétil na coxa superior esquerda. A tomografia contrastada mostrou um pseudoaneurisma da aorta torácica descendente e o projétil no interior da artéria femoral superficial proximal esquerda. Ao exame físico, o pulso pedioso esquerdo estava diminuído e o paciente referiu dormência no hálux esquerdo. Foi realizado o reparo endovascular da aorta torácica e a tromboembolectomia/retirada do projétil por incisão femoral esquerda, ambos bem-sucedidos. Considerando que o diagnóstico de embolia balística depende de um alto grau de suspeição, os médicos que manejam pacientes com ferimentos por arma de fogo devem estar atentos a essa possibilidade.
