ABSTRACT
SUMMARY OBJECTIVE: To evaluate the value of EBUS-TBNA in the diagnosis of lung and mediastinal lesions. METHODS: Prospective cohort study that included 52 patients during a 2-year period (2016 to 2018) who underwent EBUS-TBNA. RESULTS: Among the 52 individuals submitted to the procedure, 22 (42.31%) patients were diagnosed with locally advanced lung cancer (N2 or N3 lymph node involvement). EBUS-TBNA confirmed the diagnosis of metastases from other extrathoracic tumors in the mediastinum or lung in 5 patients (9.61%), confirmed small cell lung cancer in 3 patients (5.76%), mediastinal sarcoidosis in 1 patient (1.92%), and reactive mediastinal lymph node in 8 patients (15.38%); insufficient results were found for 3 patients (5.76%). Based on these results, EBUS-TBNA avoided further subsequent surgical procedures in 39 of 52 patients (75%). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 86%, 100%, 100%, 77%, and 90%, respectively. No major complications were observed. CONCLUSIONS: EBUS-TBNA is a safe, effective, and valuable method. This technique can significantly reduce the rate of subsequent surgical procedures required for the diagnosis of lung and mediastinal lesions.
RESUMO OBJETIVO: Avaliar a importância da ecoendoscopia endobrônquica com punção por agulha fina (Ebus-TBNA) no diagnóstico das lesões pulmonares e mediastinais. MÉTODOS: Estudo prospectivo e do tipo coorte, no qual foram incluídos 52 pacientes, durante o período de dois anos (2016 a 2018), submetidos ao procedimento de Ebus-TBNA. RESULTADOS: Do total de 52 indivíduos submetidos ao procedimento, 22 (42,31%) pacientes foram diagnosticados com neoplasia pulmonar localmente avançada (N2 ou N3). O método confirmou o diagnóstico de metástases de outros tumores extratorácicos no mediastino ou pulmão em cinco pacientes (9,61%), três pacientes (5,76%) com carcinoma de pequenas células, um paciente (1,92%) com sarcoidose, oito pacientes (15,38%) com linfonodomegalias reacionais/inflamatórias e resultado insuficiente em três pacientes (5,76%). O Ebus-TBNA evitou a realização de outros procedimentos cirúrgicos subsequentes em 39 de 52 (75%) pacientes. Foram calculados os valores de sensibilidade de 86%, especificidade de 100%, valor preditivo positivo de 100%, valor preditivo negativo de 77% e acurácia de 90%. Não foram observadas complicações maiores pelo método neste estudo. CONCLUSÃO: O Ebus-TBNA é um método seguro, eficaz e de relevante importância. Este exame pode reduzir significativamente o número de procedimentos invasivos subsequentes necessários para o diagnóstico das lesões pulmonares e mediastinais.

Summary An 82-year-old man sought our service with dysphagia and was referred for upper endoscopy with biopsies, which evidenced multiple ulcers of the esophagus and oropharinx. Histopathology confirmed the unusual diagnosis of esophageal lichen planus. The correct clinical suspicion of this disease can facilitate the diagnosis and guide specific treatment, which can drastically change the natural course of the disease.
Resumo Paciente do sexo masculino, de 82 anos, com disfagia, foi encaminhado para realização de endoscopia digestiva alta com biópsias, na qual foram evidenciadas múltiplas úlceras de esôfago e orofaringe. O estudo histopatológico confirmou o diagnóstico raro de líquen plano esofágico. A correta suspeita clínica dessa doença pode facilitar o diagnóstico e direcionar para um tratamento específico, o que pode drasticamente alterar o curso natural dessa comorbidade.

Summary Necrotizing pancreatitis with fluid collections can occur as a complication of acute pancreatitis. The management of these patients depends on the severity and involves multiple medical treatment modalities, as clinical intensive care and surgical intervention. In this article, we show a severe case of walled-off pancreatic necrosis that was conducted by endoscopic drainage with great clinical outcome.
Resumo Pancreatite necrosante com coleções pode ocorrer como complicação da pancreatite aguda. O manejo desses pacientes depende da gravidade e envolve múltiplas modalidades médicas de tratamento, como terapia clínica intensiva e intervenção cirúrgica. Neste artigo, mostramos um caso grave de necrose pancreática com ótima resolução clínica após drenagem endoscópica.

PURPOSE: To evaluate the diagnosis improvement of EUS-FNA when using ROSE performed by the endosonographer. METHODS: A retrospective study was conducted. A total of 48 pancreatic solid masses EUS-FNA were divided into two groups according to the availability of on-site cytology (ROSE) - the first 24 patients (group A-without ROSE) and the latter 24 cases (group B-with ROSE). Sensitivity, specificity, positive predictive value, negative predictive value, accuracy, complications and inadequacy rate of EUS-FNA were determined and compared. RESULTS: Among the 48 EUS-FNA, the overall performance was: sensitivity 82%; specificity 100%; positive predictive value (PPV) 100%; negative predictive value (NPV) 70% and accuracy 87%. The sensitivity of the Group A was 71%, versus 94% in-group B (p=0.61). Moreover, the negative predictive value was 58% versus 87% (p=0.72). The accuracy rate increased from 79% to 96% (p=0.67) in the ROSE group. The number of punctures was similar between the groups. No major complications were reported. CONCLUSION: Rapid on-site cytopathological examination, even when performed by the endosonographer, may improve the diagnostic performance in the diagnosis of solid pancreatic lesions, regardless of the slight increase in the number of punctures. .

A gastroenterologia sofreu uma verdadeira revolução com a introdução da endoscopia digestiva, principalmente a partir da década de 1960, com o desenvolvimento de novas técnicas e o aprimoramento do conhecimento científico. A endoscopia digestiva alta (EDA) ocupa um papel muito importante no arsenal diagnóstico e terapêutico na prática médica, em especial graças ao extraordinário avanço tecnológico ocorrido nos últimos anos. Atualmente, é possível avaliar e conduzir de maneira mais precisa as patologias gastrointestinais, entre elas as diversas formas de esofagites, gastrites, lesões pépticas, neoplásicas, vasculares e corpos estranhos, com melhor acurácia diagnóstica e menores complicações. A EDA é o principal e o mais importante método disponível na abordagem da hemorragia digestiva alta (HDA), tanto para o diagnóstico como para a terapêutica, com consequente influência no prognóstico dos pacientes. Além disso, exerce papel fundamental na avaliação e retirada dos corpos estranhos no trato digestivo, reduzindo de forma importante a morbimortalidade dos indivíduos acometidos por essa comorbidade. Com base nisso, o objetivo desse estudo é mostrar os resultados encontrados nos exames de EDA, realizados em âmbito ambulatorial ou emergencial, em um centro de treinamento em endoscopia digestiva.
Gastroenterology underwent a revolution with the introduction of endoscopy, mainly from the 1960, with the development of new techniques and the improvement of scientific knowledge. Upper endoscopy (EGD) occupies a very important role in diagnosis and therapeutics in medical practice, mainly due to the extraordinary technological advances of recent years. Currently, it is possible to evaluate and conduct more accurately the gastrointestinal disorders, including various forms of esophagitis, gastritis, peptic lesions, neoplastic, vascular, and foreign bodies, most accurate diagnoses and fewer complications. The EDA is the main and most important method available in the approach to upper gastrointestinal bleeding (UGIB), both for diagnosis and for therapy, with consequent influence on the prognosis of patients. Furthermore, plays a fundamental role in the evaluation and removal of foreign bodies in the digestive tract, greatly reducing the morbidity and mortality of individuals affected by this comorbidity. Based on this, the objective of this study is to show the results of EDA exams performed in outpatient or emergency context, a training center for endoscopy.
