Pulmonary inflammation and viral replication define distinct clinical outcomes in fatal cases of COVID-19.

COVID-19 has affected more than half a billion people worldwide, with more than 6.3 million deaths, but the pathophysiological mechanisms involved in lethal cases and the host determinants that determine the different clinical outcomes are still unclear. In this study, we assessed lung autopsies of 47 COVID-19 patients and examined the inflammatory profiles, viral loads, and inflammasome activation. Additionally, we correlated these factors with the patient's clinical and histopathological conditions. Robust inflammasome activation was detected in the lungs of lethal cases of SARS-CoV-2. Experiments conducted on transgenic mice expressing hACE2 and infected with SARS-CoV-2 showed that Nlrp3-/- mice were protected from disease development and lethality compared to Nlrp3+/+ littermate mice, supporting the involvement of this inflammasome in disease exacerbation. An analysis of gene expression allowed for the classification of COVID-19 patients into two different clusters. Cluster 1 died with higher viral loads and exhibited a reduced inflammatory profile than Cluster 2. Illness time, mechanical ventilation time, pulmonary fibrosis, respiratory functions, histopathological status, thrombosis, viral loads, and inflammasome activation significantly differed between the two clusters. Our data demonstrated two distinct profiles in lethal cases of COVID-19, thus indicating that the balance of viral replication and inflammasome-mediated pulmonary inflammation led to different clinical outcomes. We provide important information to understand clinical variations in severe COVID-19, a process that is critical for decisions between immune-mediated or antiviral-mediated therapies for the treatment of critical cases of COVID-19.

Canine pulmonary clearance during feto-neonatal transition according to the type of delivery.

The success of immediate adaptation to extrauterine life depends on appropriate lung function, however, elective cesarean section can increase the risk of respiratory distress as a result of reduced pulmonary fluid absorption. This study aimed to evaluate the influence of birth mode on pulmonary clearance and respiratory performance of canine neonates in the transition period. For this purpose, 37 neonates were selected according to the obstetric condition: Vaginal Eutocia (n = 17) and Elective C-section (n = 20). Neonates were evaluated for neonatal vitality score, as well as evaluation of heart and respiratory rates, body temperature and body weight, venous hemogasometric evaluation, blood lactate and glucose, pulse oximetry and radiographic evaluation during the first 24 h of life. Additionally, amniotic fluid electrolyte composition of each puppy was evaluated. There was no influence of the type of delivery on electrolyte composition of canine amniotic fluid and neonatal pulmonary liquid content, analyzed by thoracic X-Rays. On the other hand, elective cesarean section delayed pulmonary adaptation, resulting in hypoxemia and less efficient compensatory response to acid-base imbalance and thermoregulation. In conclusion, elective c-section does not delay pulmonary clearance, whilst alters pulmonary adaptation by less efficient gas exchange and lower oxygenation, hindering the compensatory response to acid-base imbalance during the fetal-neonatal transition in dogs.

Activities of the oral health teams in primary health care: a time-motion study.

BACKGROUND: Efficient planning of the oral health workforce in Primary Health Care (PHC) is paramount to ensure equitable community access to services. This requires a meticulous examination of the population's needs, strategic distribution of oral health professionals, and effective human resource management. In this context, the average time spent on care to meet the needs of users/families/communities is the central variable in healthcare professional workforce planning methods. However, many time measures are solely based on professional judgment or experience. OBJECTIVE: Calculate the average time parameters for the activities carried out by the oral health team in primary health care. METHOD: This is a descriptive observational study using the time-motion method carried out in five Primary Health Care Units in the city of São Paulo, SP, Brazil. Direct and continuous observation of oral health team members occurred for 40 h spread over five days of a typical work week. RESULTS: A total of 696.05 h of observation were conducted with 12 Dentists, three Oral Health Assistants, and five Oral Health Technicians. The Dentists' main activity was consultation with an average duration of 24.39 min, which took up 42.36% of their working time, followed by documentation with 12.15%. Oral Health Assistants spent 31.57% of their time on infection control, while Oral Health Technicians spent 22.37% on documentation. CONCLUSION: The study establishes time standards for the activities performed by the dental care team and provides support for the application of workforce planning methods that allow for review and optimization of the work process and public policies.

The knowledge of primary health care professionals regarding mental health: diagnosis by mhGAP.

OBJECTIVE: To analyze knowledge about priority topics in mental health care of strategic actors who work in regions where the Health Care Planning (PAS) methodology is used. METHODS: This is a quantitative, descriptive, cross-sectional, and observational study carried out with professionals from six health regions, distributed in three Brazilian states (Goiás, Rondônia and Maranhão) and linked to the project "Saúde mental na APS" (Mental health in PHC) of the Programa de Apoio ao Desenvolvimento Institucional do Sistema Único de Saúde (Proadi-SUS - Institutional Development Support Program of the Brazilian Unified Health System). The sample was made up of professionals who participated in the intervention guide multiplier training stage for mental, neurological and alcohol and other drug use disorders in the primary health care network, from July to September 2022. Data collection was through a self-administered instrument, in electronic format, consisting of a block with socioeconomic items and a structured questionnaire to assess participants' knowledge about priority topics in mental health. Descriptive analyses and comparison of proportions were conducted to analyze the data. RESULTS: A total of 354 health professionals participated in the study. Regarding the percentage of correct answers in the questionnaire on priority topics in mental health, the highest medians were identified in the "Depression" module. On the other hand, the content referring to the modules "Essential care and practices" and "Other important complaints" presented the lowest values. Furthermore, some participant characteristics were found to be associated with the percentage of correct answers in the questionnaire modules. CONCLUSIONS: The findings reveal opportunities for improvement, mainly in knowledge related to communication skills and the approach to emotional and physical distress without diagnostic criteria for a specific disease, offering support for planning actions aimed at intensifying the consideration of these themes during the operational stages of PAS.

Implementation of a digital tool for population management in Primary Health Care.

OBJECTIVE: Describe the implementation of a digital diagnostic and territorial monitoring tool in primary healthcare. METHODS: Quantitative and qualitative study, developed in 14 basic healthcare units in São Paulo, with community health workers, coordinators, nurses, and physicians. Data collection occurred in four phases: analysis of the instruments used by the team for territory management; development of the digital tool; training and implementation; and evaluation after 90 days using focus groups. Descriptive analyses were conducted by calculating absolute and relative frequencies to treat quantitative data. Qualitative data were subjected to content analysis. RESULTS: Three hundred thirty-four professionals participated in the study. In the first step, territory management's main challenges were filling out various instruments, system failures, data inconsistency, internet infrastructure/network, and lack of time. Therefore, a digital tool was developed consisting of 1) a spreadsheet recording the number of family members and markers of health conditions, date of visit, and number of return visits; 2) a spreadsheet with a summary of families visited, not visited, and refusals; and 3) a panel with a summary of the data generated instantly. In the evaluation, after the initial use of the tool, the themes that emerged were integration of the tool into daily work, evaluation of the digital tool implementation process, and improvement and opportunities for improvement. CONCLUSIONS: Faced with the challenges faced by family healthcare teams when filling out systems and managing the territory, the tool developed provided greater reliability and agility in data visualization, reduced the volume of instruments, and optimized the work process.

Brazilian Scale for Evaluation of Mental Health Care Needs: Additional Evidence.

OBJECTIVE: To investigate validity evidence of the Brazilian Scale for Evaluation of Mental Health Care Needs (CuidaSM). METHODS: This is a psychometric study, which seeks additional evidence of internal structure. Data collection was carried out in 11 Primary Health Care (PHC) services , which implement the Health Care Planning (HCP) methodology, distributed across the five Brazilian regions. The preliminary version of CuidaSM, containing a block self-referred by the user and another block evaluated by PHC professionals, was applied to users aged 18 or over who attended the PHC services for consultation with a higher education professional. The techniques of confirmatory factor analysis and network analysis were used to investigate validity evidence. For the primary data of the confirmatory factor analysis, the factorial loads and the item's predictive power (R2) were used. Six model adjustment indices were adopted and reliability was measured by three indicators using Bayesian estimation. RESULTS: A total of 879 users participated in the study. By confirmatory factor analysis, factorial loads ranged from 0.43 to 0.99 and R2 from 0.19 to 0.98. Both the primary indicators and the model adequacy indices were established at satisfactory and consistent levels. The network analysis showed that the items were appropriately associated with their peers, respecting the established dimensions, which again indicates the sustainability and stability of the proposed model. CONCLUSIONS: The study findings confirm a consistent and reliable model of the instrument, through a combination of techniques. Considering the importance of using solid instruments in clinical practice, CuidaSM is a promising tool for population-based management and network care organization, aligned with HCP proposals.

Evaluation of humoral immune response after yellow fever infection: an observational study on patients from the 2017-2018 sylvatic outbreak in Brazil.

Between 2016 and 2018, Brazil experienced major sylvatic yellow fever (YF) outbreaks that caused hundreds of casualties, with Minas Gerais (MG) being the most affected state. These outbreaks provided a unique opportunity to assess the immune response triggered by the wild-type (WT) yellow fever virus (YFV) in humans. The plaque reduction neutralization test (PRNT) is currently the standard method to assess the humoral immune response to YFV by measuring neutralizing antibodies (nAbs). The present study aimed to evaluate the humoral immune response of patients from the 2017-2018 sylvatic YF outbreak in MG with different disease outcomes by using PRNTs with a WT YFV strain, isolated from the 2017-2018 outbreak, and a vaccine YFV strain. Samples from naturally infected YF patients were tested, in comparison with healthy vaccinees. Results showed that both groups presented different levels of nAb against the WT and vaccine strains, and the levels of neutralization against the strains varied homotypically and heterotypically. Results based on the geometric mean titers (GMTs) suggest that the humoral immune response after a natural infection of YFV can reach higher levels than that induced by vaccination (GMT of patients against WT YFV compared to GMT of vaccinees, P < 0.0001). These findings suggest that the humoral immune responses triggered by the vaccine and WT strains of YFV are different, possibly due to genetic and antigenic differences between these viruses. Therefore, current means of assessing the immune response in naturally infected YF individuals and immunological surveillance methods in areas with intense viral circulation may need to be updated.IMPORTANCEYellow fever is a deadly febrile disease caused by the YFV. Despite the existence of effective vaccines, this disease still represents a public health concern worldwide. Much is known about the immune response against the vaccine strains of the YFV, but recent studies have shown that it differs from that induced by WT strains. The extent of this difference and the mechanisms behind it are still unclear. Thus, studies aimed to better understand the immune response against this virus are relevant and necessary. The present study evaluated levels of neutralizing antibodies of yellow fever patients from recent outbreaks in Brazil, in comparison with healthy vaccinees, using plaque reduction neutralization tests with WT and vaccine YFV strains. Results showed that the humoral immune response in naturally infected patients was higher than that induced by vaccination, thus providing new insights into the immune response triggered against these viruses.

Maternal and neonatal cortisol and catecholamines throughout vaginal eutocia and C-section in dogs.

Increased fetal cortisol is associated with catecholamine release, a primary factor for neonatal adaptive responses. However, relationship between canine peripartum cortisol and catecholamine is unknown. We aimed to compare serum adrenaline, noradrenaline and cortisol during peripartum in bitches and neonates of distinct obstetric conditions and to assess amniotic fluid cortisol concentration. Twenty females and maximum of three puppies per litter were allocated into Vaginal Eutocia (10 females; 17 neonates) and Elective C-section (10 females; 20 neonates) groups. Amniotic fluid was collected at delivery for cortisol concentration. Maternal and neonatal blood were collected prepartum, intrapartum, postpartum and 1h postpartum, and at birth, 30 and 60min, 12hs and 24hs, respectively, for cortisol, adrenaline and noradrenaline assessment. C-section determined higher noradrenaline throughout delivery and cortisol concentration from intrapartum through 1h postpartum, compared to vaginal birth. C-section maternal cortisol showed progressive increase from intrapartum onwards, while neonatal cortisol remained unchanged. No difference of maternal cortisol concentration occurred along whelping, whereas a significant decrease was verified for vaginal delivery puppies from birth until the 12hs. Puppies delivered vaginally had higher cortisol concentration at birth and 30min, compared to c-section puppies. There was a higher concentration of amniotic fluid cortisol in vaginal eutocia. In conclusion, c-section induces higher maternal stress during and after surgery, whilst vaginal delivery is a more neonatal physiologically stressful condition, contributing to better adaptation during transition.

Challenges and strategies for conducting research in primary health care practice: an integrative review.

BACKGROUND: Providing accessible and high-quality patient-centered healthcare remains a challenge in many countries, despite global efforts to strengthen primary health care (PHC). Research and knowledge management are integral to enhancing PHC, facilitating the implementation of successful strategies, and promoting the use of evidence-based practices. Practice-based research in primary care (PC-PBR) has emerged as a valuable approach, with its external validity to diverse PHC settings, making it an effective means of translating research findings into professional practice. OBJECTIVE: To identify challenges and strategies for conducting practice-based research in primary health care services. METHOD: An integrative literature review was conducted by searching the PubMed, Embase, Scopus, Web of Science, and Lilacs databases. The research question, guided by the PICo framework, directed the execution of study selection and data extraction. Data analysis followed the RAdAR method's three phases: pre-analysis, data analysis, and interpretation of results. RESULTS: Out of 440 initially identified articles, 26 met the inclusion criteria. Most studies were conducted in high-income countries, primarily the United States. The challenges and strategies for PC-PBR were categorized into six themes: research planning, infrastructure, engagement of healthcare professionals, knowledge translation, the relationship between universities and health services, and international collaboration. Notable challenges included research planning complexities, lack of infrastructure, difficulties in engaging healthcare professionals, and barriers to knowledge translation. Strategies underscore the importance of adapting research agendas to local contexts, providing research training, fostering stakeholder engagement, and establishing practice-based research networks. CONCLUSION: The challenges encountered in PC-PBR are consistent across various contexts, highlighting the need for systematic, long-term actions involving health managers, decision-makers, academics, diverse healthcare professionals, and patients. This approach is essential to transform primary care, especially in low- and middle-income countries, into an innovative, comprehensive, patient-centered, and accessible healthcare system. By addressing these challenges and implementing the strategies, PC-PBR can play a pivotal role in bridging the gap between research and practice, ultimately improving patient care and population health.

ANALYSIS OF THE TRACKING INITIATIVES OF COLORECTAL CANCER IN BRAZIL.

BACKGROUND: Colorectal cancer (CRC) is an important public health problem, as it represents the world's third most diagnosed neoplasm and the fourth cause of mortality. Its prevention can be divided into primary, secondary, demonstrated by tracking techniques, and tertiary, which consists of cancer diagnosis in symptomatic patients. Despite presenting a high incidence, the mortality rates decreased in the past two decades in developed countries, while the opposite happened in underdeveloped countries. That is attributed to the increase of colorectal cancer tracking programs in developed countries, which allows the precocious diagnosis and treatment of precancerous injuries and CRC. In that manner, the American Cancer Society divides the secondary tracking methods in exams based on feces samples and visual analysis of the colon and rectum, indicating its initiation starting at 45 years old in lower-risk patients. OBJECTIVE: Verify in an analytical way the actions of colorectal cancer tracking held in Brazil, as to evaluate the necessity of implementation of a national tracking program of CRC. METHODS: The methodology was based on a descriptive-quantitative secondary study that correlated the incidence of CRC, its morbidity and mortality, and the impact of the precocious tracking programs. It included activities not reported in medical literature through personal contacts with coordinators of regional programs to compare with the existent data in the literature. It was used as a variable for the tracking strategies the exams held, and their respective results. RESULTS: It described nine programs held in different regions in Brazil, using two screening methods for CRC: a noninvasive method that consists of the research of blood hidden in feces, being the majority through the FIT method, and an invasive method, having the colonoscopy as its representant. These initiatives were effective in the detection of early forms of this disease. CONCLUSION: Despite the existence of several private tracking programs and the broad divulgation of the importance of the tracking and the early diagnosis of colorectal cancer, it was demonstrated that Brazil lacks a national program that patronizes the tracking methods, which reflects in the major prevalence of late diagnosis in the population.

RESUMO Contexto: O câncer colorretal (CCR) é um importante problema de saúde pública, uma vez que representa a terceira neoplasia mais diagnosticada no mundo e a quarta causa de mortalidade. Sua prevenção pode ser dividida em primária, secundária, demonstrada pelas técnicas de rastreamento e terciária, que consiste no diagnóstico de câncer em pacientes sintomáticos. Apesar de apresentar uma alta incidência, as taxas de mortalidade diminuíram nas últimas duas décadas nos países desenvolvidos, enquanto o contrário ocorreu em países subdesenvolvidos, o que atribui-se a elevação dos programas de rastreamento colorretal nesses países, de modo que permite o diagnóstico precoce e o tratamento de lesões pré-cancerosas e do CCR. Desse modo, a American Cancer Society divide os métodos de rastreio secundário em testes baseados em amostras de fezes e exames visuais do cólon e reto, indicando-se seu início a partir dos 45 anos de idade, em pacientes de baixo risco. Objetivo: Verificar de forma analítica as ações de rastreamento do câncer colorretal realizadas no Brasil, de modo a avaliar a necessidade da implementação de um programa nacional de rastreamento do CCR. Métodos: A metodologia baseou-se em um estudo secundário quantitativo descritivo que correlacionou a incidência do CCR e sua morbimortalidade e o impacto dos programas de rastreamento precoce. Foram incluídas atividades não relatadas na literatura médica através de contatos pessoais com coordenadores de programas regionais, de modo a comparar com os dados existentes na literatura. Utilizou-se como variáveis as estratégias de triagem, os exames realizados e seus respectivos resultados. Resultados: Foram descritos nove programas realizados em diversas regiões do Brasil utilizando dois métodos de rastreio para o CCR, um não invasivo que consiste na pesquisa de sangue oculto nas fezes, sendo a maioria pelo método FIT; e outro invasivo, tendo a colonoscopia como representante. Essas iniciativas foram efetivas na detecção de formas precoces desta doença. Conclusão: Apesar da existência de diversos programas de rastreamento de início privativo e a ampla divulgação da importância do rastreamento e diagnóstico precoce do CCR, foi demonstrado que o Brasil carece de um programa nacional que padronize as formas de rastreio, o que reflete na maior prevalência de diagnósticos tardios na população.

Matricide and schizophrenia- psychopathological, psychodynamic, and forensic aspects: a case report.

Matricide is the murder of a mother by her son or daughter, a form of homicide rarely seen in psychiatric practice. A narrative review was conducted on the relationship between matricide and schizophrenia, followed by a case report in Brazil of a schizophrenic patient who murdered his mother and was submitted to forensic psychiatric assessment for criminal liability. The article discusses psychopathological, psychodynamic, and forensic aspects related to the case. The observation of ambivalent and conflictive relations between schizophrenic individuals and their mothers suggests the need for family-level interventions to resolve the understandable occurrence of emotional conflicts, which can serve as stimuli that trigger the murder.

Overweight in adolescents: a possible association between sleep quality and eating behavior according to sex / Sobrepeso en adolescentes: una posible asociación entre la calidad del sueño y el comportamiento alimentario según el sexo

Introduction: Obesity is a multifactorial disease affectingadolescent sleep quality and binge eating.Objective: to analyze adolescents’ sleep quality and possible binge eating according to sex and nutritional status. Methods: 108 adolescents (n = 51 male and n = 57 female) aged between 10 to 18 years were recruited. Bodycomposition was assessed by bioelectrical impedance, inwhich the following variables were collected: body weight,body fat percentage, and resting metabolic rate. The Zscorewas calculated and classified by height and weight as eutrophic and overweight. Subsequently, the adolescents answered the Brazilian version of the Pittsburgh Sleep QualityIndex (PSQI) questionnaire and the binge eating - PeriodicEating Compulsion Scale (BES) questionnaire to assess possible periodic eating compulsion. Results: In the anthropometric analysis, male adolescentsshowed greater height (p<0.0001), body weight (p<0.05),resting metabolic rate (p<0.0001), total body water(p<0.0001), lean mass (p<0.0001), fatfree mass (p<0.0001)and skeletal muscle mass (p= 0.01) compared to female adolescents. However, female adolescents had a higher body fatpercentage when compared to male adolescents (p= 0.01).In addition, overweight adolescents of both sexes had high BES scores compared to eutrophic ones (p<0.05), with higherscores for females compared to males (p<0.05). However, nodifferences were observed between overweight and eutrophicindividuals of both sexes for PQSI (p>0.05). Conclusion: Binge eating was identified in both sexes andmay be related to poor sleep qualit.(AU)

Introducción: La obesidad es una enfermedad multifactorial que afecta la calidad del sueño y los atracones en los adolescentes. Objetivo: analizar la calidad del sueño y los posibles atracones en adolescentes según sexo y estado nutricional. Métodos: se reclutaron 108 adolescentes (n = 51 hombres y n = 57 mujeres) con edades entre 10 y 18 años. Se midió el Z-score y se clasificó por estatura y peso corporal en eutróficos y sobrepeso. Posteriormente, los adolescentes respondieron la versión brasileña del cuestionario Pittsburgh Sleep Quality Index (PSQI) y el cuestionario Binge Eating Scale (BES) para evaluar la posible compulsión alimentaria periódica.

Conclusión: Los atracones se identificaron en ambos sexos y pueden estar relacionados con la mala calidad del sueño.(AU)

Use of life cycle assessment as a tool to evaluate the environmental impacts of textile effluents: a systematic review.

The textile industry is known for its large consumption of water, energy, and chemical products, making it one of the most environmentally impactful activities. To measure these environmental impacts, life cycle analysis (LCA) is a powerful tool that considers the entire process, from the extraction of raw materials to the finalization of textile products. In this context, this work aimed to present a systematic study on the use of the LCA methodology in the environmental assessment of effluents from the textile industry. The survey for data was carried out using the Scopus and Web of Science databases, and the PRISMA method was utilized for organizing and selecting of articles. During the meta-analysis phase bibliometric and specific data were extracted from selected publications. For the bibliometric analysis, a quali-quantitative approach was adopted, and the VOSviewer software was employed. The review encompasses a total of 29 articles, which were published between 1996 and 2023.The majority of the reviewed articles have shown the use of the LCA as a supportive tool for optimization focusing on sustainability, comparing the environmental, economic, and technical aspects through different approaches. The findings revel that China has the highest number of authors among the selected articles, while researchers from France and Italy had the highest number of international collaborations. The ReCiPe and CML methods were the most frequently used for evaluating life cycle inventories, with global warming, terrestrial acidification, ecotoxicity, and ozone depletion being the main impact categories. The use of activated carbon in textile effluents treatment has shown to be promising since it is environmentally friendly.

Oropouche virus infection induces ROS production and oxidative stress in liver and spleen of mice.

Oropouche virus (OROV) is the aetiological agent of Oropouche fever, the symptoms of which are common to most arboviruses, such as fever, headache, malaise, nausea and vomiting. More than half a million people have been infected with OROV since its isolation in 1955. Although Oropouche fever is classified as a neglected and emerging disease, to date, there are no antiviral drugs or vaccines available against the infection and little is known about its pathogenicity. Therefore, it is essential to elucidate the possible mechanisms involved in its pathogenesis. Since oxidative stress plays a pivotal role in the progression of various viral diseases, in this study, redox homeostasis in the target organs of OROV infection was evaluated using an animal model. Infected BALB/c mice exhibited reduced weight gain, splenomegaly, leukopenia, thrombocytopenia, anaemia, development of anti-OROV neutralizing antibodies, increased liver transaminases, and serum levels of pro-inflammatory cytokines tumour necrosis factor (TNF-α) and interferon-γ (IFN-γ). The OROV genome and infectious particles were detected in the liver and spleen of infected animals, with liver inflammation and an increase in the number and total area of lymphoid nodules in the spleen. In relation to redox homeostasis in the liver and spleen, infection led to an increase in reactive oxygen species (ROS) levels, increased oxidative stress biomarkers malondialdehyde (MDA) and carbonyl protein, and decreased activity of the antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT). Taken together, these results help elucidate some important aspects of OROV infection that may contribute to the pathogenesis of Oropouche.

Mental Health Care in Primary Health Care: An Integrative Review.

In this study, we analyzed recent studies on mental health approaches developed in primary health care to identify the emphasis of such interventions, their technical feasibility for the setting in question, and their levels of evidence. An integrative review was conducted of primary studies from the LILACS, PubMed, Embase, CINAHL, and Web of Science databases using the PRISMA search strategy. Nineteen studies were identified with a high level of evidence that contribute to the advancement of knowledge in the area. However, academic, cultural, and linguistic barriers still need to be overcome to facilitate sharing of such interventions' findings and protocols.

Endoscopic ultrasound-guided biliary drainage: a literature review.

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.
