Abstract: Pt Es En

A cardiomiopatia hipertrófica (CMH) é uma forma de doença do músculo cardíaco de causa genética, caracterizada pela hipertrofia das paredes ventriculares. O diagnóstico requer detecção por métodos de imagem (Ecocardiograma ou Ressonância Magnética Cardíaca) de qualquer segmento da parede do ventrículo esquerdo com espessura > 15 mm, sem outra causa provável. A análise genética permite identificar mutações de genes codificantes de diferentes estruturas do sarcômero responsáveis pelo desenvolvimento da CMH em cerca de 60% dos casos, permitindo o rastreio de familiares e aconselhamento genético, como parte importante do manejo dos pacientes e familiares. Vários conceitos sobre a CMH foram recentemente revistos, incluindo sua prevalência de 1 em 250 indivíduos, não sendo, portanto, uma doença rara, mas subdiagnosticada. A vasta maioria dos pacientes é assintomática. Naqueles sintomáticos, a obstrução do trato de saída do ventrículo esquerdo (OTSVE) é o principal distúrbio responsável pelos sintomas, devendo-se investigar a sua presença em todos os casos. Naqueles em que o ecocardiograma em repouso ou com Manobra de Valsalva não detecta gradiente intraventricular significativo (> 30 mmHg), devem ser submetidos à ecocardiografia com esforço físico para detecção da OTSVE.   Pacientes com sintomas limitantes e grave OTSVE, refratários ao uso de betabloqueadores e verapamil, devem receber terapias de redução septal ou uso de novas drogas inibidoras da miosina cardíaca. Por fim, os pacientes adequadamente identificados com risco aumentado de morta súbita podem receber medida profilática com implante de cardiodesfibrilador implantável (CDI).

La miocardiopatía hipertrófica (MCH) es una forma de enfermedad cardíaca de origen genético, caracterizada por el engrosamiento de las paredes ventriculares. El diagnóstico requiere la detección mediante métodos de imagen (Ecocardiograma o Resonancia Magnética Cardíaca) que muestren algún segmento de la pared ventricular izquierda con un grosor > 15 mm, sin otra causa probable. El análisis genético permite identificar mutaciones en genes que codifican diferentes estructuras del sarcómero responsables del desarrollo de la MCH en aproximadamente el 60% de los casos, lo que permite el tamizaje de familiares y el asesoramiento genético, como parte importante del manejo de pacientes y familiares. Varios conceptos sobre la MCH han sido revisados recientemente, incluida su prevalencia de 1 entre 250 individuos, por lo tanto, no es una enfermedad rara, sino subdiagnosticada. La gran mayoría de los pacientes son asintomáticos. En los casos sintomáticos, la obstrucción del tracto de salida ventricular izquierdo (TSVI) es el trastorno principal responsable de los síntomas, y su presencia debe investigarse en todos los casos. En aquellos en los que el ecocardiograma en reposo o la maniobra de Valsalva no detecta un gradiente intraventricular significativo (> 30 mmHg), deben someterse a ecocardiografía de esfuerzo para detectar la obstrucción del TSVI. Los pacientes con síntomas limitantes y obstrucción grave del TSVI, refractarios al uso de betabloqueantes y verapamilo, deben recibir terapias de reducción septal o usar nuevos medicamentos inhibidores de la miosina cardíaca. Finalmente, los pacientes adecuadamente identificados con un riesgo aumentado de muerte súbita pueden recibir medidas profilácticas con el implante de un cardioversor-desfibrilador implantable (CDI).

Hypertrophic cardiomyopathy (HCM) is a form of genetically caused heart muscle disease, characterized by the thickening of the ventricular walls. Diagnosis requires detection through imaging methods (Echocardiogram or Cardiac Magnetic Resonance) showing any segment of the left ventricular wall with a thickness > 15 mm, without any other probable cause. Genetic analysis allows the identification of mutations in genes encoding different structures of the sarcomere responsible for the development of HCM in about 60% of cases, enabling screening of family members and genetic counseling, as an important part of patient and family management. Several concepts about HCM have recently been reviewed, including its prevalence of 1 in 250 individuals, hence not a rare but rather underdiagnosed disease. The vast majority of patients are asymptomatic. In symptomatic cases, obstruction of the left ventricular outflow tract (LVOT) is the primary disorder responsible for symptoms, and its presence should be investigated in all cases. In those where resting echocardiogram or Valsalva maneuver does not detect significant intraventricular gradient (> 30 mmHg), they should undergo stress echocardiography to detect LVOT obstruction. Patients with limiting symptoms and severe LVOT obstruction, refractory to beta-blockers and verapamil, should receive septal reduction therapies or use new drugs inhibiting cardiac myosin. Finally, appropriately identified patients at increased risk of sudden death may receive prophylactic measure with implantable cardioverter-defibrillator (ICD) implantation.

ABSTRACT Objective: This study aimed to describe the clinical characteristics of the pediatric population with COVID-19 in an Emergency Department (ED) of a Brazilian general hospital. Methods: Epidemiological and clinical data of patients younger than 20 years old were collected from patients’ medical records from February 2020 to July 2021. Most of the epidemiological data described pertains to hospitalized patients. We also reviewed coinfections, treatment, and outcomes and compared the first and second waves of COVID-19. Results: We identified a total of 1303 episodes of SARS-CoV-2 infection. The median time from symptom onset to diagnosis was three days. Symptoms were present in 92.3% of the patients. The most common symptoms were fever (45.2%), nasal congestion/discharge (44.2%), and cough (39.4%). Chest radiography and tomography were performed in 7.7 and 3.3% of cases, with abnormal findings in 29.7 and 53.4%, respectively. Hospital admissions occurred in 3.5% of patients, mainly in the presence of comorbidities, in children under five years old and in those who presented to the ED during the first wave of COVID-19. Coinfection with a viral agent was identified in 20% of the 71 cases tested in this study, and a positive rapid test for Streptococcus pyogenes was found in 8% of the 174 cases tested, with no impact of these coinfections on hospitalization. Conclusions: We found that COVID-19 was a mild disease in most children in our study population, with most hospitalizations and readmissions occurring during the first wave of COVID-19.

RESUMO Objetivo: Este estudo teve como objetivo descrever as características clínicas da população pediátrica com COVID-19 no setor de emergência de um hospital geral brasileiro. Métodos: Os dados epidemiológicos e clínicos de pacientes idade inferior a 20 anos foram coletados dos prontuários dos pacientes de fevereiro de 2020 a julho de 2021. A maior parte dos dados epidemiológicos descritos refere-se a pacientes hospitalizados. Também foram revisados as coinfecções, o tratamento e os desfechos de internação e comparadas a primeira e a segunda ondas de COVID-19. Resultados: Foi identificado o total de 1.303 episódios de infecção por SARS-CoV-2. A mediana de tempo desde o início dos sintomas até o diagnóstico foi de três dias. Os sintomas estiveram presentes em 92,3% dos pacientes. Os sintomas mais comuns foram febre (45,2%), congestão/secreção nasal (44,2%) e tosse (39,4%). Radiografia e tomografia de tórax foram realizadas em 7,7 e 3,3% dos casos, com achados anormais em 29,7 e 53,4%, respectivamente. As internações hospitalares ocorreram em 3,5% dos pacientes, principalmente na presença de comorbidades, em crianças menores de cinco anos e naqueles que se apresentaram no pronto-socorro durante a primeira onda de COVID-19. Foi identificada coinfecção viral em 20% dos 71 casos testados e teste rápido positivo para Streptococcus pyogenes em 8% dos 174 casos testados, não havendo impacto dessas coinfecções quanto à internação hospitalar. Conclusões: Observamos que a COVID-19 foi uma doença leve na maioria das crianças de nossa população, com a maior parte das hospitalizações e readmissões ocorrendo durante a primeira onda de COVID-19.

Abstract The geotechnical monitoring of tailings dams combined with a suitable application of geophysical electrical methods can improve their structure evaluation, allowing several correlations between direct analyses and the resistivity anomaly pattern. Considering this synergy, twenty-three electrical resistivity sections (ERT) were acquired along the beach, abutments, and central part of a dam, totalizing 10,776 m of dataset. After the interpretation of each ERT section, comparing the anomaly ranges with the water level meters measurements, three resistivity zones were defined: Zones of low resistivity (<64 ohm-m), correlated to regions of high humidity; zones of high resistivity (> 357 ohm-m), interpreted as dry zones, and regions with intermediate resistivity values, located between these limits. The groundwater surface generated from the interpretation of the electrical resistivity dataset and the groundwater surface acquired from the water level gauges were almost coincident. On the right abutment, the conductive anomalies showed remarkable continuity, suggesting a high moisture content in this region with strong gradients (200 mV) directed towards the zone of low resistivity values identified in the sections. The analysis showed a robust correlation of the ERT data with localized physical geotechnical measurements, valuable for monitoring dam integrity, overseeing the structure's response to climate and operational changes, and ultimately mitigating the risks of failure. The results of this study support the adoption of a seasonal 4D electrical resistivity survey as an effective tool to monitor and manage surface and high humidity zones, key indicators of dam integrity throughout the entire structure.

ABSTRACT The tropical forest is extremely exploited and fragmented, making it essential to collect native seeds to meet the growing demand for its restoration and maintenance of biodiversity. Thus, the objective is to select potential forest fragments with a higher degree of conservation for seed harvesting, through the use and association of landscape ecology with fuzzy logic. The study was carried out in the watershed of the Itapemirim river. The stages of selection and photointerpretation of the images were carried out; error determination; application of landscape ecology metric indices; application of fuzzy logic in a computational application and validation of the methodology in loco. 7,515 forest fragments were determined, corresponding to 19.21% of the study area, with 89.53% of hits. Fragments smaller than 5 ha are the most fragile and are at risk of extinction, while those larger than 300 ha have a lower risk of extinction, even with the increase in the edge. With the application of fuzzy logic, the mean was between 0.15, standard deviation of 0.24 and the coefficient of variation at 161.73%. Scenario 1 (FLONA of Pacotuba), has 10.25% of families, 25.92% of genera and 33.62% of species more than Scenario 2 (PEAMA Ifes Campus of Alegre), among the identified individuals. The association of landscape ecology techniques and fuzzy logic made it possible to identify fragments with a higher degree of conservation, with potential for harvesting forest seeds.

RESUMO A floresta tropical é extremamente explorada e fragmentada, sendo imprescindível a coleta de sementes nativas, a fim de atender a crescente demanda para sua restauração e manutenção da biodiversidade. Dessa forma, objetiva-se selecionar fragmentos florestais potenciais com maior grau de conservação para a colheita de sementes, via utilização e associação da ecologia da paisagem à lógica Fuzzy. O estudo foi realizado na bacia hidrográfica do rio Itapemirim. Foram realizadas as etapas de seleção e fotointerpretação das imagens; determinação do erro; aplicação dos índices métricos de ecologia da paisagem; aplicação da lógica Fuzzy em aplicativo computacional e validação da metodologia in loco. Foram determinados 7.515 fragmentos florestais, correspondendo a 19,21% da área de estudo, com 89,53% de acertos. Os fragmentos menores que 5 ha são os mais frágeis e possuem risco de extinção, enquanto os maiores que 300 ha possuem menor risco de extinção, mesmo com o aumento da borda. Com a aplicação da lógica Fuzzy, a média ficou entre 0,15, desvio padrão de 0,24 e o coeficiente de variação em 161,73 %. O Cenário 1 (FLONA de Pacotuba) possui 10,25% de famílias, 25,92 % de gêneros e 33,62% de espécies a mais que o Cenário 2 (PEAMA Ifes Campus de Alegre), entre os indivíduos identificados. A associação das técnicas de ecologia da paisagem e lógica Fuzzy possibilitou identificar os fragmentos em maior grau de conservação, com potencial para colheita de sementes florestais.

ABSTRACT Objective: To update the recommendations to support decisions regarding the pharmacological treatment of patients hospitalized with COVID-19 in Brazil. Methods: Experts, including representatives of the Ministry of Health and methodologists, created this guideline. The method used for the rapid development of guidelines was based on the adoption and/or adaptation of existing international guidelines (GRADE ADOLOPMENT) and supported by the e-COVID-19 RecMap platform. The quality of the evidence and the preparation of the recommendations followed the GRADE method. Results: Twenty-one recommendations were generated, including strong recommendations for the use of corticosteroids in patients using supplemental oxygen and conditional recommendations for the use of tocilizumab and baricitinib for patients on supplemental oxygen or on noninvasive ventilation and anticoagulants to prevent thromboembolism. Due to suspension of use authorization, it was not possible to make recommendations regarding the use of casirivimab + imdevimab. Strong recommendations against the use of azithromycin in patients without suspected bacterial infection, hydroxychloroquine, convalescent plasma, colchicine, and lopinavir + ritonavir and conditional recommendations against the use of ivermectin and remdesivir were made. Conclusion: New recommendations for the treatment of hospitalized patients with COVID-19 were generated, such as those for tocilizumab and baricitinib. Corticosteroids and prophylaxis for thromboembolism are still recommended, the latter with conditional recommendation. Several drugs were considered ineffective and should not be used to provide the best treatment according to the principles of evidence-based medicine and to promote resource economy.

RESUMO Objetivo: Atualizar as recomendações para embasar as decisões para o tratamento farmacológico de pacientes hospitalizados com COVID-19 no Brasil. Métodos: A elaboração desta diretriz foi feita por especialistas, incluindo representantes do Ministério da Saúde e metodologistas. O método utilizado para o desenvolvimento rápido de diretrizes baseou-se na adoção e/ou adaptação de diretrizes internacionais existentes (GRADE ADOLOPMENT) e contou com o apoio da plataforma e-COVID-19 RecMap. A qualidade das evidências e a elaboração das recomendações seguiram o método GRADE. Resultados: Chegaram-se a 21 recomendações, incluindo recomendações fortes quanto ao uso de corticosteroides em pacientes em uso de oxigênio suplementar e recomendações condicionais para o uso de tocilizumabe e baricitinibe, em pacientes com oxigênio suplementar ou ventilação não invasiva, e de anticoagulantes, para prevenção de tromboembolismo. Devido à suspensão da autorização de uso, não foi possível fazer recomendações para o tratamento com casirivimabe + imdevimabe. Foram feitas recomendações fortes contra o uso de azitromicina em pacientes sem suspeita de infecção bacteriana, hidroxicloroquina, plasma convalescente, colchicina e lopinavir + ritonavir, além de recomendações condicionais contra o uso de ivermectina e rendesivir. Conclusão: Foram criadas novas recomendações para o tratamento de pacientes hospitalizados com COVID-19, como as recomendações de tocilizumabe e baricitinibe. Ainda são recomendados corticosteroides e profilaxia contra tromboembolismo, esta em caráter condicional. Vários medicamentos foram considerados ineficazes e não devem ser usados, no intuito de proporcionar o melhor tratamento segundo os princípios da medicina baseada em evidências e promover a economia de recursos.

Abstract Background Frontotemporal dementia (FTD) is a frequent cause of young-onset dementia and represents a major challenge for the diagnosis and clinical management. It is essential to evaluate the difficulties faced by physicians on the diagnostic workup and on patient care. Objective The aim of this study was to investigate the current practices and the local limits on the diagnosis and management of FTD in Brazil. Methods We elaborated an online survey, composed of 29 questions and divided in four parts, comprising questions about existing health facilities, clinical practices related to FTD, and suggestions to increment the national research on FTD. The invitation to participate was sent by email to all neurologists affiliated to the Brazilian Academy of Neurology (n = 3658), and to all physicians who attended the XII Meeting of Researchers on Alzheimer's disease, in 2019 (n = 187). The invitation was also diffused through social media. Results 256 Brazilian physicians answered the questionnaire. The three most relevant disorders for the differential diagnosis of FTD were Alzheimer's disease (AD) (n = 211), bipolar disorder (n = 117) and dementia with Lewy bodies (n = 92). Most respondents (125/256) reported the difficulty in performing genetic testing as the main limit in the diagnostic of FTD. 93% and 63% of participants considered that the assessment of social cognition and AD CSF biomarkers are useful for the diagnosis of FTD, respectively. Conclusions The present study may provide valuable insights for the medical education and clinical training of physicians, and to foster future research on FTD in Brazil.

Resumo Antecedentes A demência frontotemporal (DFT) é causa frequente de demência pré-senil e representa um desafio em termos de diagnóstico e de manejo clínico. É essencial avaliar as dificuldades existentes na propedêutica e nos cuidados médicos. Objetivo Investigar as práticas médicas e as dificuldades para diagnóstico e manejo da DFT no Brasil. Métodos Elaborou-se um questionário online, composto de 29 questões, divididas em quatro partes, com perguntas sobre infraestrutura existente, práticas clínicas relacionadas à DFT e sugestões para desenvolver a pesquisa nacional na área. O convite para participação foi enviado por e-mail a todos neurologistas afiliados à Academia Brasileira de Neurologia (n = 3658), e aos médicos que participaram da XII Reunião de Pesquisadores de Doença de Alzheimer, em 2019 (n = 187). O convite também foi divulgado através de mídias sociais. Resultados 256 médicos brasileiros responderam o questionário. Os três principais diagnósticos diferenciais de DFT foram doença de Alzheimer (n = 211), transtorno bipolar (n = 117) e demência com corpos de Lewy (n = 92). A maior parte dos respondedores (125/256) apontou a dificuldade em realizar testagem genética como o maior limite no diagnóstico de DFT. 93% e 63% dos respondedores indicaram que a avaliação de cognição social e o uso de biomarcadores liquóricos de doença de Alzheimer são úteis no diagnóstico de DFT, respectivamente. Conclusões Estes resultados devem ser considerados na educação e treinamento médicos, e no desenvolvimento da pesquisa brasileira em DFT.

ABSTRACT The use of echocardiography by physicians who are not echocardiographers has become common throughout the world across highly diverse settings where the care of acutely ill patients is provided. Echocardiographic evaluation performed in a point-of-care manner can provide relevant information regarding the mechanism of causes of shock, for example, increasing the rates of correct diagnosis and allowing for faster informed decision-making than through evaluation methods. Considering that the accurate diagnosis of life-threatening situations is essential for professionals working with acutely ill patients, several international associations recommend that physicians responsible for critically ill patients acquire and develop the ability to perform bedside ultrasound examinations, including echocardiographic examinations. However, there is no consensus in the literature regarding which specific applications should be included in the list of skills for nonechocardiographer physicians. Taking into account the multiplicity of applications of echocardiography in different scenarios related to acutely ill patients; the differences in the published protocols, with regard to both the teaching methodology and competence verification; and the heterogeneity of training among highly diverse specialties responsible for their care at different levels, this consensus document aimed to reflect the position of representatives of related Brazilian medical societies on the subject and may thus serve as a starting point both for standardization among different specialties and for the transmission of knowledge and verification of the corresponding competencies.

RESUMO O emprego da ecocardiografia por médicos não ecocardiografistas tem se tornado comum em todo o mundo nos mais diversos ambientes em que se dá o cuidado do paciente agudamente doente. A avaliação ecocardiográfica realizada de forma point-of-care pode fornecer informações pertinentes em relação ao mecanismo das causas de choque, por exemplo, incrementando as taxas de diagnóstico correto e possibilitando a tomada de decisão fundamentada de forma mais rápida do que por meio dos métodos tradicionais de avaliação. Considerando que o diagnóstico preciso de situações ameaçadoras à vida é indispensável a profissionais atuando junto a pacientes agudamente enfermos, diversas entidades associativas internacionais recomendam que médicos responsáveis por pacientes gravemente doentes devam adquirir e desenvolver a habilidade para realizar exames ultrassonográficos à beira do leito, inclusive ecocardiográficos. Entretanto, não há consenso na literatura acerca de quais aplicações específicas devam compor o rol de habilidades do médico não ecocardiografista. Levando-se em consideração a multiplicidade de aplicações da ecocardiografia em diversos cenários relativos ao paciente agudamente enfermo; as diferenças nos protocolos publicados, tanto no que diz respeito à metodologia de ensino como de verificação de competências, bem como a heterogeneidade da formação entre as mais diversas especialidades responsáveis pelo seu cuidado em diferentes níveis, este documento de consenso teve o objetivo de refletir o posicionamento de representantes de sociedades médicas brasileiras afins acerca do tema, podendo, assim, servir de ponto de partida para a uniformização entre diferentes especialidades, bem como para a transmissão de conhecimento e a verificação das competências correspondentes.

Resumo Neste trabalho é apresentado um estudo sobre a ruptura do concreto por pry-out em conectores de cisalhamento tipo Crestbond com o objetivo de obter um modelo de cálculo que estima a resistência da conexão a esse modo de falha. As análises foram realizadas por meio de simulações numéricas capazes de reproduzir o referido modo de falha. Os resultados numéricos são comparados com os experimentais e discutidos em relação à força máxima atingida e o aspecto da fissuração típica do pry-out. O modelo de cálculo proposto apresentou boa correspondência com os resultados experimentais, com uma razão média Pteo/Pexp igual a 0,99 e um coeficiente de variação de 10%. Os valores encontrados nesse estudo sugerem que a expressão da Aprovação Técnica Alemã para outros conectores pode ser aplicada nos conectores Crestbond.

Abstract In this work, a study on failure by concrete pry-out in Crestbond shear connectors is presented. The study’s aim was the development of an expression that estimates the connection’s bearing capacity. The analyses were carried out through numerical simulations designed to reproduce the referred failure mode. Numerical and experimental results are compared and discussed in relation to the maximum force reached and the cracking aspect typical of concrete pry-out. The proposed equation corresponded well to experimental results, with a mean ratio Ptheo/Pexp equal to 0,99 and a coefficient of variation of 10%. The results found in this study indicate that the concrete pry-out expression in German Technical Approval Z-26.4-56 can also be applied to Crestbond shear connectors.

ABSTRACT. Selection practices are maximized when plant breeders have the availability of consolidated parameters, which will guide direct and indirect selection methods. This study aimed to apply a biometric alternative to minimize residual variance and maximize selection parameters by parent-progeny regression, interim controls, and mixed linear models intrinsic to breeding. The obtained data were subjected to the assumptions of the statistical model, which identified the normality and homogeneity of the residual variances and model additivity. Subsequently, two analysis scenarios were created. The first preserved all information obtained in the experiment, both from segregating families and pure-line cultivars, and was called original scenario. The other scenario preserved progeny data, but the residual variability of controls was restricted using as criterion observations contained between the interval of the first sample standard deviation. Thereby, an acceptable residue limit could be obtained. Both scenarios were submitted to three consolidated frequentist methods (genitor-progeny regression; sum of squares of augmented block design with interim controls; and mixed linear models, wherein random genetic effects are taken as weighted genetic parameters by the genealogical matrix). Restricting residual variation in parents or controls can maximize genetic parameters and genetic gains in soybean breeding. Significant heritability estimate gains were obtained in the augmented blocks with interim control approach. Mixed linear models with random genetic effects can be considered a great tool to obtain genetic parameters in experiments with a high magnitude of common and regular treatments.

ABSTRACT Objective: the aim of this study was to compare the results of open and videolaparoscopic transvesical prostatectomy techniques in the treatment of benign prostatic hyperplasia (BPH) in a tertiary hospital. Methods: we reviewed medical records of patients who underwent transvesical adenectomy due to BPH between March 2019 and March 2021 at the urology service of Hospital de Clínicas do Paraná (HCPR), 42 patients were included in the open transvesical prostatectomy group and 22 in the videolaparoscopic group. Then, a comparison was made between the techniques in terms of surgical time, bleeding, length of stay, need for intensive care, among others, in addition to postoperative outcome. Results: the mean surgical time was shorter in the open technique compared to the laparoscopic technique (141 min vs 274 min). The videolaparoscopic group had a shorter mean hospital stay (3.5 days vs 6.36 days). There was no statistical significance in the comparison regarding the need for an intensive care unit, as well as in the assessment of postoperative bleeding. Conclusion: comparatively, the techniques demonstrated a similar outcome, with a low rate of complications and satisfactory results for the treatment of BPH. The laparoscopic technique is a surgery with a shorter hospital stay, but at the expense of a longer surgical time.

RESUMO Objetivo: o objetivo deste estudo foi comparar o resultado das técnicas de prostatectomia transvesical aberta e videolaparoscópica no tratamento de hiperplasia prostática benigna (HPB) em um hospital terciário. Métodos: foram revisados prontuários de pacientes submetidos a adenectomia transvesical devido a HPB entre março de 2019 a março de 2021 no serviço de urologia do Hospital de Clínicas do Paraná (HCPR), sendo incluídos 42 pacientes no grupo prostatectomia transvesical aberta e 22 no grupo videolaparoscópico. Em seguida foi feita a comparação entre as técnicas nos quesitos tempo cirúrgico, sangramento, tempo de internamento, necessidade de terapia intensiva, entre outras, além de desfecho pós-operatório. Resultados: o tempo cirúrgico médio foi menor na técnica aberta em comparação com a técnica videolaparoscópica (141 min vs 274 min). O grupo videolaparoscópico apresentou um tempo médio de internamento menor (3,5 dias vs 6,36 dias). Não houve significância estatística na comparação quanto a necessidade de unidade de terapia intensiva, assim como na avaliação do sangramento pós-operatório. Conclusão: comparativamente, as técnicas demonstraram um desfecho semelhante, com baixa taxa de complicações e resultados satisfatórios para o tratamento da HPB. Sendo a técnica videolaparoscópica uma cirurgia com menor tempo de internamento, porém às custas de um maior tempo cirúrgico. .
