Abstract We investigated the Biogran on bone repair and metabolism at several time-intervals upon grafting into rat tibia artificial defects. The biomaterial was thoroughly characterized in vitro, and its dissolution behavior upon immersion was assessed in simulated body fluid (SBF) solution for 1, 3, 7, 14, and 30 days. Biogran was also assessed by in vitro hydroxyapatite formation in SBF solution, which is a marker for bioactive behavior. In vivo, distal and proximal bone defects were performed in the Wistar rat's right tibia and filled according to the experimental groups: I) negative control, no filling; II) positive control, 10 mg of autogenous bone; and III) 10 mg of Biogran. Animals were euthanized at 1, 2, 3, 4, 7, and 10 weeks. Bone neoformation was analyzed using histomorphometry (proximal defect), and local levels of bone morphogenetic protein 2 (BMP-2) were measured using the ELISA assay (distal defect). In vitro, the Biogran sample showed a fast dissolution rate within the first 7 days, parallel to the formation of the hydroxyapatite layer. In vivo, the sample was progressively resorbed at a higher rate within the first month until it became almost absent at week 10th. The sample presented similar or higher bone neoformation concerning the autogenous bone. BMP-2 levels were sustained in the Biogran group (around 200 pg/mg) and detected until the last experimental time with a significant difference compared with the controls. Results suggest Biogran is a candidate for hard tissue engineering even in highly active bone remodeling sites.

Abstract This study examined the oral health-related therapeutic itineraries of quilombola adults in a rural district of Vitória da Conquista, Bahia. This qualitative study involved ten semi-structured interviews of adult members of the quilombola community, in May 2021, which were then transcribed and analysed using content analysis. The results showed little or poor oral hygiene at some stage of life, especially in childhood and adolescence, the use of popular oral health care practices, and experiences of professional care featuring tooth extraction. Use of health services was mostly reported only in the period prior to the COVID-19 pandemic. Responses as to perceived ease of access to health services in the community varied. One common complaint as to satisfaction with oral health was the need to use or replace dental prostheses. This study concluded that oral health must be promoted jointly with disease prevention, dental rehabilitation and recognition for the knowledge and worldview of the quilombola population.

Resumo O estudo analisou os itinerários terapêuticos relacionados à saúde bucal de adultos quilombolas de um distrito rural de Vitória da Conquista, Bahia. Trata-se de uma pesquisa qualitativa, na qual foram realizadas dez entrevistas semiestruturadas com adultos quilombolas em maio de 2021, transcritas e analisadas por meio da análise de conteúdo. Os resultados evidenciaram ausência e/ou precariedade na higiene bucal em alguma fase da vida, especialmente infância e adolescência; utilização de práticas populares para cuidado a saúde bucal e experiências de cuidado profissional marcados pela exodontia. A utilização de serviços de saúde foi relatada, em sua maioria, apenas no período anterior à pandemia de COVID-19, os entrevistados divergiram quanto à percepção de facilidade do acesso aos serviços de saúde em sua comunidade. Os relatos sobre a satisfação da saúde bucal destacaram a necessidade de uso ou substituição de próteses dentárias. À guisa de conclusão, entende-se que é necessária a promoção de saúde bucal de forma articulada com ações que possibilitem a prevenção de agravos, a reabilitação odontológica e a valorização do conhecimento e da visão de mundo da população quilombola.

ABSTRACT: The current production of major crops, such as Glycine max L., has become increasingly adept on the use of bio-inputs, such as application of plant growth-promoting inocula. However, the evaluation of the potential of bacterial isolates from soils with different time histories of agricultural use are still scarce, and methods for isolation and testing of multifunctional microorganisms need to be continuously innovated and improved. Thus, we used G. max bait plants to attract rhizobacteria from soils obtained from three areas with different time histories of soybean cultivation. We evaluated the influence of the management and characteristics of soils on the phosphate-solubilizing bacterial population. We then tested the multifunctional potential of the isolated rhizobacteria for calcium phosphate (CaHPO4) and iron phosphate (FePO4) solubilization, considering their potential as microbial inoculants in the future. The use of bait plants enabled the isolation of 139 phosphate solubilizing rhizobacteria, including four strains with multifunctional potential. The largest number of solubilizing bacteria was obtained from the interaction of bait plants with soil from an area with a history of soybean cultivation for thirty consecutive years. The high concentration of P, Fe, and K found in the soil were associated with this occurrence. In the in vitro tests, the pH values of the culture media had a moderate negative relationship with the amounts of P made available by the isolates, indicating that other processes besides the availability of organic acids, may underlie the solubilizing action of the isolates. The rhizobacteria SAF9 (Brevibacillus sp.), SAF11 (Brevibacillus sp.), BRC11 (Pseudomonas fluorescens), and SAC36 (Bacillus velezensis) stood out as multifunctional and are indicated within a perspective of obtaining bioinoculants to promote plant growth directly, indirectly, or synergistically, contributing to increase the range of bio-inputs for soybean cultivation and more sustainable agricultural practices.

RESUMO: A produção atual de grandes culturas, como Glycine max L. tem se mostrado cada vez mais adepta da utilização de bioinsumos, como a aplicação de inóculos promotores do crescimento vegetal. No entanto, avaliações do potencial de isolados bacterianos de solos com diferentes históricos de tempo de uso agrícola ainda são escassos e os métodos para isolamento e testagem de micro-organismos multifuncionais precisam ser continuamente inovados e melhorados. Assim, usamos plantas iscas de G. max para atrair rizobactérias de solos obtidos de três áreas com diferentes históricos de cultivo de soja. Avaliamos a influência do manejo e das características dos solos sobre a população de bactérias solubilizadoras de fosfato. Em seguida, testamos o potencial multifuncional das rizobactérias isoladas para solubilização de fosfato de cálcio (CaHPO4) e fosfato de ferro (FePO4), considerando seu potencial como inoculantes microbianos no futuro. O uso de plantas iscas permitiu o isolamento de 139 rizobactérias solubilizadoras de fosfato, incluindo quatro cepas com potencial multifuncional. O maior número de bactérias solubilizadoras foi obtido a partir da interação das plantas-isca com o solo de uma área com histórico de cultivo de soja por trinta anos consecutivos. Características como a alta concentração de P, Fe e K neste solo, estiveram associadas a esta ocorrência. Nos testes in vitro, os valores de pH dos meios de cultivo se correlacionaram negativamente, mas de forma moderada com as quantidades de P disponibilizados pelos isolados, indicando que outros processos, além da disponibilização de ácidos orgânicos podem estar subjacentes à ação solubilizadora dos isolados. As rizobactérias SAF9 (Brevibacillus sp.), SAF11 (Brevibacillus sp.), BRC11 (Pseudomonas fluorescens) e SAC36 (Bacillus velezensis) se destacaram como multifuncionais e são indicadas dentro de uma perspectiva de obtenção de bioinoculantes para promoção do crescimento vegetal de forma direta, indireta ou sinérgica, contribuindo para aumentar a gama de bioinsumos destinados à cultura da soja e para práticas agrícolas mais sustentáveis.

Abstract Background Genes and their variants associated with environmental factors contribute to the development of the hypertensive phenotype. The G protein beta 3 subunit gene (GNB3) is involved in the intracellular signaling process, and its variants have been related to susceptibility to arterial hypertension. Objective To determine the association of the GNB3 variant (rs5443:C>T) with arterial hypertension, biochemical parameters, age, and obesity in hypertensive and normotensive individuals from Ouro Preto, Minas Gerais, Brazil. Method The identification of variants was performed by real-time PCR, using the TaqMan® system, in 310 samples (155 hypertensive and 155 normotensive). Biochemical analyses (renal function, lipid profile and glycemia) were performed from the serum using UV/Vis spectrophotometry and ion-selective electrode. A multiple logistic regression model was used to identify factors associated with arterial hypertension. The analysis of continuous variables with normal distribution was performed using the unpaired Student’s t test; non-normal data were analyzed using Mann-Whitney. P < 0.05 was considered significant. Results The rs5443:C>T variant was not associated with arterial hypertension in the evaluated population (p = 0.88). Regarding biochemical measures, the T allele was associated with high levels of triglycerides, glucose and uric acid in hypertensive individuals (p < 0.05). Conclusion These results show the importance of genetic diagnosis to prevent the causes and consequences of diseases and imply that the GNB3 rs5443:C>T variant may be associated with changes in the biochemical profile in hypertensive individuals.

Resumo Fundamento Genes e suas variantes associadas a fatores ambientais contribuem para o desenvolvimento do fenótipo hipertenso. O gene da subunidade beta 3 da proteína G ( GNB3 ) está envolvido no processo de sinalização intracelular e suas variantes têm sido relacionadas à suscetibilidade à hipertensão arterial. Objetivo Determinar a associação da variante GNB3 (rs5443:C>T) com a hipertensão arterial, parâmetros bioquímicos, idade e obesidade em indivíduos hipertensos e normotensos de Ouro Preto, Minas Gerais. Método A identificação das variantes foi realizada por PCR em tempo real, utilizando o sistema TaqMan®, em amostras de 310 pacientes (155 hipertensos e 155 normotensos). Análises bioquímicas (função renal, perfil lipídico e glicemia) foram realizadas a partir do soro por meio de espectrofotometria UV/Vis e eletrodo íon-seletivo. Foi utilizado um modelo de regressão logística múltipla para identificar fatores associados à hipertensão arterial. A análise das variáveis contínuas com distribuição normal foi realizada usando o teste t de Student não pareado; dados não normais foram analisados usando o teste de Mann-Whitney. Valores de p < 0,05 foram considerados significativos. Resultados A variante rs5443:C>T não esteve associada à hipertensão arterial na população avaliada (p = 0,88). Em relação às medidas bioquímicas, o alelo T esteve associado a níveis elevados de triglicerídeos, glicose e ácido úrico em indivíduos hipertensos (p < 0,05). Conclusão Os presentes resultados mostram a importância do diagnóstico genético para prevenir as causas e consequências de doenças e sugerem que a variante GNB3 rs5443:C>T pode estar associada a alterações no perfil bioquímico em indivíduos hipertensos.

Abstract New methods of early detection and risk assessment have been studied aiming to predict the prognosis of patients and directing a specialized treatment of the oral tongue squamous cell carcinoma (OTSCC). In this context, several molecular biomarkers have been investigated for this purpose, and, among them, the heat shock protein 27 (HSP27) can be named. The study aimed to analyze whether heat shock protein 27 (HSP27) exerts any influence on OTSCC, correlating its immunoexpression with clinicopathological parameters, and patient survival. The sample comprised 55 OTSCC cases and 20 normal oral mucosa specimens. The malignancy grading systems proposed by the WHO in 2005, Brandwein-Gensler et al., and Almangush et al. were applied in a histomorphological study. HSP27 expressions were evaluated through the Immunoreactivity Score System (IRS). Significant values were considered at p <0.05 for all statistical tests. Higher IRS results were observed for normal oral mucosa specimens when compared to OTSCC cases (p <0.001). No significant associations between HSP27 immunostaining, the analyzed clinicopathological parameters and patient survival were observed. The results of the present study indicate lower HSP27 expression in OTSCC cases compared to normal oral mucosa specimens. Thus, HSP27 expression does not seem to influence patient prognosis.

Resumo Novos métodos de detecção precoce e avaliação de risco estão sendo estudados com o intuito de predizer o prognóstico dos pacientes e direcionar um tratamento diferenciado. Neste contexto, vários biomarcadores moleculares têm sido investigados com esta finalidade, dentre eles a heat shock protein 27 (HSP27). Esta pesquisa objetivou analisar se a HSP27 exerce alguma influência nos carcinomas de células escamosas de língua oral (CCELO), correlacionando a sua imunoexpressão com parâmetros clinicopatológicos e com a sobrevida dos pacientes. A amostra foi constituída por 55 casos de CCELO e 20 espécimes de mucosa oral normal. Os sistemas de gradação de malignidade propostos pela OMS em 2005, Brandwein-Gensler et al. e Almangush et al. foram aplicados em um estudo histomorfológico. A expressão da HSP27 foi avaliada através do Sistema de Escore de Imunorreatividade (IRS). Para todos os testes estatísticos foram considerados valores significativos com p<0,05. Foi observado um maior IRS para a mucosa oral normal quando comparado aos casos de CCELO (p<0,001). Não foram encontradas associações significativas entre a imunomarcação da HSP27 com os parâmetros clinicopatológicos analisados e com a sobrevida dos pacientes. Os resultados do presente estudo indicam uma menor expressão da HSP27 nos casos de CCELO quando comparados aos espécimes de mucosa oral normal. Assim, a expressão da HSP27 parece não influenciar o prognóstico dos pacientes.

Abstract Objective To analyze the impact of the COVID-19 pandemic on the residency of gynecology and obstetrics in São Paulo. Methods Cross-sectional study developed by representatives of residents of the Association of Gynecology and Obstetrics of the State of São Paulo (SOGESP, in the Portuguese acronym). Data were collected from questionnaires applied to gynecology and obstetrics residents registered on the SOGESP website in February 2022. The interviewees answered about the repercussions of the pandemic on medical residency and whether they had technical and psychological support during the period. Results A total of 247 questionnaires were collected from residents of gynecology and obstetrics. The residents had an age of 28.3 ± 3 years old, and most of them were female (88.4%). The displacement to COVID care was reported by 62.34% of the students, but only 35.6% reported completely adequate personal protective equipment and only 7.7% reported complete theoretical and technical instruction to support these patients. Almost all of the interviewees stated that the gynecology sector was the most affected. The majority of the interviewees considered that the second-year residents had the greatest loss, and more than half of the residents in the 1st and 2nd year said they wished to give up their residency during the pandemic. More than 80% of the residents reported online theoretical classes and/or presentation of articles, reinforcing the fact that virtual activities gained a greater space within the medical residency. Conclusion The pandemic impacted the residency in greater proportion in outpatient clinics and gynecological surgeries, also interfering with the physician's desire to continue with the program.

Resumo Objetivo Analisar o impacto pandemia de COVID-19 sobre a residência de ginecologia e obstetrícia do Estado de São Paulo. Métodos Estudo transversal desenvolvido por representantes dos residentes da Associação de Ginecologia e Obstetrícia do Estado de São Paulo (SOGESP). Foram coletados dados de questionários aplicados aos residentes de ginecologia e obstetrícia cadastrados no site da SOGESP em fevereiro de 2022. Os entrevistados responderam sobre repercussões da pandemia sobre a residência médica e se tiveram suporte técnico e psicológico durante o período. Resultados Foram levantados 247 questionários de residentes de ginecologia e obstetrícia. Os residentes apresentaram idade de 28,3 ± 3 anos, sendo a maioria do sexo feminino (88,4%). O deslocamento para “covidários” foi referido por 62,34% dos avaliados, porém somente 35,6% referiram equipamento de proteção individual completamente adequado e apenas 7,7% referiram instrução completa teórica e técnica para o suporte destes pacientes. Quase a totalidade dos entrevistados afirmou que o setor de ginecologia foi o mais afetado. A maioria dos entrevistados considerou que o os residentes do segundo ano foram os que tiveram maior prejuízo, sendo que mais da metade dos residentes do 1° e 2° ano afirmou ter desejado desistir da residência durante a pandemia. Mais de 80% dos residentes referiram aulas teóricas e/ou apresentação de artigos online, reforçando o fato de que as atividades virtuais ganharam um espaço maior dentro da residência médica. Conclusão A pandemia impactou nas residências em maior proporção nos ambulatórios e cirurgias ginecológicas, interferindo também sobre o desejo do médico de seguir com o programa.

Abstract Introduction Malignant Hyperthermia (MH) is an inherited hypermetabolic syndrome triggered by exposure to halogenated anesthetics/succinylcholine. The lack of knowledge regarding this condition might be associated with the rare occurrence of MH reaction and symptoms. Methods This observational study evaluated 68 patients from 48 families with confirmed or suspected MH susceptibility due to medical history of MH reaction or idiopathic increase of creatine kinase or MH-related myopathies. Participants were assessed by a standardized questionnaire and submitted to physical/neurological examination to assess the characteristics of patients with MH, their knowledge about the disease, and the impact suspected MH had on their daily lives. Results Suspected MH impacted the daily life of 50% of patients, creating difficulties in performing surgical/clinical/dental treatment and problems related to their family life/working/practicing sports. The questionnaire on MH revealed a correct answer score of 62.1 ± 20.8 (mean ± standard deviation) on a scale 0 to 100. Abnormal physical/neurological examination findings were detected in 92.6% of susceptible patients. Conclusions Suspected MH had impacted the daily lives of most patients, with patients reporting problems even before MH investigation with IVCT. Patients showed a moderate level of knowledge about MH, suggesting the need to implement continuing education programs. MH susceptible patients require regular follow-up by a health team to detect abnormalities during physical and neurological examination.

Abstract Background Malignant Hyperthermia (MH) is a pharmacogenetic disorder triggered by halogenated anesthesia agents/succinylcholine and characterized by hypermetabolism crisis during anesthesia, but also by day-to-day symptoms, such as exercise intolerance, that may alert the health professional. Objective The study aimed to analyze the incidence of fatigue in MH susceptible patients and the variables that can impact perception of fatigue, such as the level of routine physical activity and depression. Methods A cross-sectional observational study was carried out with three groups - 22 patients susceptible to MH (positive in vitro muscle contracture test), 13 non-susceptible to MH (negative in vitro muscle contracture test) and 22 controls (no history of MH). Groups were assessed by a demographic/clinical questionnaire, a fatigue severity scale (intensity, specific situations, psychological consequences, rest/sleep response), and the Beck depression scale. Subgroups were re-assessed with the Baecke habitual physical exercise questionnaire (occupational physical activity, leisure physical exercise, leisure/locomotion physical activity). Results There were no significant differences among the three groups regarding fatigue intensity, fatigue related to specific situations, psychological consequences of fatigue, fatigue response to resting/sleeping, depression, number of active/sedentary participants, and the mean time and characteristics of habitual physical activity. Nevertheless, unlike the control sub-group, the physically active MH-susceptible subgroup had a higher fatigue response to resting/sleeping than the sedentary MH susceptible subgroup (respectively, 5.9 ± 1.9 vs. 3.9 ± 2, t-test unpaired, p< 0.05). Conclusion We did not detect subjective fatigue in MH susceptible patients, although we reported protracted recovery after physical activity, which may alert us to further investigation requirements.

Abstract Introduction Malignant Hyperthermia (MH) is a pharmacogenetic, hereditary and autosomal dominant syndrome triggered by halogenates/succinylcholine. The In Vitro Contracture Test (IVCT) is the gold standard diagnostic test for MH, and it evaluates abnormal skeletal muscle reactions of susceptible individuals (earlier/greater contracture) when exposed to caffeine/halothane. MH susceptibility episodes and IVCT seem to be related to individual features. Objective To assess variables that correlate with IVCT in Brazilian patients referred for MH investigation due to a history of personal/family MH. Methods We examined IVCTs of 80 patients investigated for MH between 2004‒2019. We recorded clinical data (age, sex, presence of muscle weakness or myopathy with muscle biopsy showing cores, genetic evaluation, IVCT result) and IVCT features (initial and final maximum contraction, caffeine/halothane concentration triggering contracture of 0.2g, contracture at caffeine concentration of 2 and 32 mmoL and at 2% halothane, and contraction after 100 Hz stimulation). Results Mean age of the sample was 35±13.3 years, and most of the subjects were female (n=43 or 54%) and MH susceptible (60%). Of the 20 subjects undergoing genetic investigation, 65% showed variants in RYR1/CACNA1S genes. We found no difference between the positive and negative IVCT groups regarding age, sex, number of probands, presence of muscle weakness or myopathy with muscle biopsy showing cores. Regression analysis revealed that the best predictors of positive IVCT were male sex (+12%), absence of muscle weakness (+20%), and personal MH background (+17%). Conclusions Positive IVCT results have been correlated to male probands, in accordance with early publications. Furthermore, normal muscle strength has been confirmed as a significant predictor of positive IVCT while investigating suspected MH cases.

Abstract BACKGROUND: Severe acute respiratory syndrome coronavirus 2 has several mechanisms of action related to inflammatory responses, especially in individuals diagnosed with obesity. This hyperinflammatory clinical profile resulting from the association between obesity and coronavirus disease 2019 (COVID-19) may be attenuated by regular physical activity. OBJECTIVE: The aim of this study was to review the evidence on the consequences of physical inactivity and physical activity on COVID-19 in patients with obesity. DESIGN AND SETTING: Narrative review at the Bahiana School of Medicine and Public Health in Salvador, Brazil. METHODS: We searched evidence on the association of COVID-19 with physical activity and obesity using the following keywords: “covid-19,” “physical activity,” and “obesity”. The databases used were MEDLINE (PubMed), ScienceDirect, and Virtual Health Library. Studies published from 2019 to 2021 and available in Portuguese, English, and Spanish were included. The final search was conducted on September 26, 2021. RESULTS: We identified 661 studies in the database, among which 71 were considered for inclusion in the narrative review of the molecular aspects of COVID-19 and its relationship with physical activity and obesity. CONCLUSION: This literature review enabled the perception of the relationship between the molecular mechanisms of COVID-19 and obesity. Regular physical activity had various benefits for the inflammatory condition of the studied population, highlighting moderate-intensity.

Resumo A Rede de Atenção às Urgências e Emergências (RUE) foi proposta enquanto política pública com a finalidade de articular e integrar os serviços assistenciais do Sistema Único de Saúde (SUS), ampliando e qualificando o acesso dos usuários em situação de urgência e emergência em saúde de forma ágil e oportuna. Este estudo tem como objetivo analisar a produção científica sobre a política da RUE no Brasil e elaborar sínteses demonstrando seus limites e desafios. Utilizou-se como método a revisão integrativa de literatura, a partir da busca de artigos nas bases de dados LILACS, SciELO e MEDLINE e de dissertações e teses na plataforma virtual da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes). A pesquisa possibilitou a análise de 34 estudos do campo da saúde coletiva, com enfoque nos diferentes serviços de urgência e a integração entre eles, incluindo possíveis transformações no processo de cuidado em saúde e distintas estratégias de avaliação, por meio de diferentes abordagens, principalmente qualitativas. São observadas fragilidades na articulação em rede, com manutenção da centralidade do componente hospitalar e o poder de seu capital simbólico, ficando a Atenção Básica relegada ao campo discursivo.

Abstract The Urgent and Emergency Care Network (RUE) was proposed in Brazil as a public policy to articulate and integrate the health services of the Brazilian National Health System (SUS), expanding and qualifying the access of users in e emergency health situations in an efficient and timely manner. This study analyzes the scientific production on the RUE in Brazil and elaborates summaries showing the limits and challenges of this health policy. An integrative literature review was used as a method, based on the search for articles in the LILACS, SciELO, and MEDLINE databases and for dissertations and theses on the virtual platform of the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). The investigation enabled the analysis of 34 studies in the field of collective health, focused on the different emergency services and the integration between them, including possible changes in the health care process and different evaluation strategies, by using different approaches, mainly qualitative. Weaknesses are observed in the network articulation, maintaining the centrality of hospital services and the power of its symbolic capital, with primary care being relegated to the discursive field.

Abstract Objective Gastroschisis (GS) is a congenital anomaly in the abdominal wall with the intestinal loops exiting laterally to the umbilicus. The contact of the loops with Amniotic Fluid (AF) causes an inflammatory process in the exposed part, leading to an extended hospital stay and an increased risk of morbidity due to alterations related to intestinal motility. The authors aimed to evaluate the time of exposure to the AF in the experimental GS and to search for potential biomarkers of intestinal inflammation by measuring microRNAs. Methods Rat fetuses were divided into three groups: a) CONTROL, b) GS reared on day 18 (GS = 18), and c) GS reared on day 19.5 (GS = 19) (term = 22 days). On day 21.5, the fetuses were removed for biometric parameters and biochemical analyses: 1) Biometrics: Body and Intestinal Weight (BW, IW), and intestinal-body weight ratio (IW/BW); 2) Descriptive histopathology and 3) miR-143 quantification by real-time Polymerase Chain Reaction (PCR). Results BW was higher in CONTROL than GS 18 and G19 (p < 0.05). IW, IW/BW, intestinal water, and mRNA-143 were higher in GS 18 and GS 19 than in CONTROL, and GS 18 was higher than GS 19 (p < 0.05). The average of the inflammation score from the intestinal wall with mucosal inflammation and intra-epithelial lymphocytes shows worst in GS 18 and GS 19 vs. CONTROL (p < 0.05). Conclusions The tissue expression of mRNA-143 and the morphological changes in the intestine of GS worsened according to the time of exposure to AF, which could be a possible marker of fetal intestinal damage.

ABSTRACT Neoplasms of the biliopancreatic confluence may present with obstruction of the bile tract, leading to jaundice, pruritus and cholangitis. In these cases drainage of the bile tract is imperative. Endoscopic retrograde cholangiopancreatography (ERCP) with placement of a choledochal prosthesis is an effective treatment in about 90% of cases, even in experienced hands. In cases of ERCP failure, therapeutic options traditionally include surgical bypass by hepaticojejunostomy (HJ) or percutaneous transparietohepatic drainage (DPTH). In recent years, endoscopic ultrasound-guided biliary drainage techniques have gained space because they are less invasive, effective and have an acceptable incidence of complications. Endoscopic echo-guided drainage of the bile duct can be performed through the stomach (hepatogastrostomy), duodenum (choledochoduodenostomy) or by the anterograde drainage technique. Some services consider ultrasound-guided drainage of the bile duct the procedure of choice in the event of ERCP failure. The objective of this review is to present the main types of endoscopic ultrasound-guided biliary drainage and compare them with other techniques.

RESUMO Neoplasias da confluência biliopancreática podem cursar com obstrução da via biliar, levando a icterícia, prurido e colangite. Nesses casos a drenagem da via biliar é imperativa. A colangiopancreatografia endoscópica retrógrada (CPER) com colocação de prótese coledociana constitui tratamento eficaz em cerca de 90% dos casos mesmo em mãos experientes. Nos casos de insucesso da CPER, tradicionalmente as opções terapêuticas incluem a derivação cirúrgica por hepaticojejunostomia (HJ) ou drenagem percutânea transparietohepática (DPTH). Nos últimos anos as técnicas endoscópicas ecoguiadas de drenagem biliar ganharam espaço por serem menos invasivas, eficazes e apresentarem incidência aceitável de complicações. A drenagem endoscópica ecoguiada da via biliar pode ser realizada pelo estômago (hepatogastrostomia), duodeno (coledocoduodenostomia) ou pela técnica de drenagem anterógrada. Alguns serviços consideram a drenagem ecoguiada da via biliar o procedimento de escolha no caso de insucesso da CPER. O objetivo desta revisão é apresentar os principais tipos de drenagem biliar endoscópica ecoguiada e confrontá-los com outras técnicas.
