“…Controversy exists over the number of EBUS‐TBNA biopsy procedures required to gain competency. Some researchers have reported that as few as 10 procedures are needed to become proficient,21, 29, 30 whereas others have reported that proficiency continues to increase up to 40 or 50 procedures 18, 31. The American Thoracic Society/European Respiratory Society officially recommends 40 procedures to obtain expertise 32…”

BACKGROUND: Endobronchial ultrasound‐guided transbronchial needle aspiration (EBUS‐TBNA) biopsy is routinely used to stage lung cancer; however, its usefulness in diagnosing lymphoproliferative disorders has not been well established. In this retrospective study, we determined the utility of EBUS‐TBNA in evaluating mediastinal lymphadenopathy in patients with suspected lymphoproliferative disorders. METHODS: The authors searched the pathology database at their institution to identify all patients who had undergone EBUS‐TBNA biopsy for possible lymphoproliferative disorders. The cytologic diagnoses were correlated with concurrent and subsequent biopsy findings and clinical follow‐up data. RESULTS: Of 886 lymph nodes evaluated by EBUS‐TBNA biopsy, 91 nodes from 33 patients (23 men and 10 women) were eligible. Fourteen patients had a history of lymphoma. Adequate material for diagnosis was obtained in 31 of 34 procedures (1 patient had 2 procedures). The cytologic diagnoses of the 31 adequate procedures included 19 with benign disease (8 reactive lymph nodes and 11 granulomatous inflammation), 8 with lymphoma (2 large B‐cell, 2 small lymphocytic, 2 Hodgkin, 1 mantle cell, and 1 T‐cell lymphoblastic), 2 with cells suspicious for Hodgkin lymphoma, and 2 cases with atypical cells. CONCLUSIONS: EBUS‐TBNA proved to be useful for evaluating mediastinal lymphadenopathy in patients with suspected lymphoproliferative disorders. Its use may decrease the need for invasive diagnostic procedures. Immediate assessment is valuable in these cases because of the need to triage material for immunophenotyping or other studies to determine optimal and clinically meaningful diagnoses.

“…[9][10][11] The yield of the method depends on the skill and care of the exami-ner, moreover it is recommended in general that a potential examiner should conduct at least 25 under the guidence of a competent practitioner before he or she is permitted to do the procedure "solo". 12,13,14 In addition, some believe that the presence of the pathologist during the procedure to identify if the specimen taken from the lymph node would improve the yield significantly. But this is still an open question.…”

“…O rendimento da PATA está diretamente relacionado ao treinamento e à experiência do examinador. 12,13 As diretrizes do American College of Chest Physicians recomendam um mínimo de 25 exames para capacitar o broncoscopista no procedimento. 14 A PATA permite acesso a onze estações de linfonodos, porém somente cinco estações são úteis no estadiamento do câncer de pulmão.…”

INTRODUÇÃO: Nos últimos anos, a punção aspirativa transbrônquica por agulha vem sendo utilizada cada vez com maior freqüência no diagnóstico e estadiamento do câncer de pulmão, principalmente nos EUA. Entretanto, muito pouco se tem publicado a respeito do método em nosso país. OBJETIVO: Avaliar a efetividade da punção aspirativa transbrônquica por agulha no diagnóstico e estadiamento do câncer de pulmão. MÉTODO: Setenta e quatro punções aspirativas transbrônquicas por agulha, realizadas no Hospital do Câncer-INCA/MS, foram revistas retrospectivamente. Todos os pacientes realizaram tomografia computadorizada do tórax previamente ao procedimento. RESULTADOS: Onze (15%) pacientes tinham massas mediastinais e 63 (85%) massas hilares. Foram encontradas 76 alterações endoscópicas: alargamento da carina principal em 44 (59%) pacientes, alargamento de carina secundária em 12 (16%), compressão paratraqueal em 5 (7%), compressão da parede posterior da traquéia em 3 (4%), e compressão de brônquio principal em 5 (7%) pacientes. O material foi satisfatório para o diagnóstico em 42 (57%) pacientes e em 34 (46%) o diagnóstico foi confirmado. O diagnóstico de doença maligna foi confirmado em 30/34 (88%) pacientes: carcinoma indiferenciado de pequenas células em 10/30 (33%), carcinoma escamoso em 7/30 (23%), adenocarcinoma em 7/30 (23%), e carcinoma não pequenas células em 6/30 (20%) pacientes. Em 4/30 (12%) pacientes foram diagnosticadas patologias benignas: tuberculose em 2/4 (50%) e sarcoidose em 2/4 (50%) pacientes. Não observamos nenhuma complicação com o método. CONCLUSÃO: Nossa experiência em 74 pacientes mostrou que o procedimento é seguro, rápido em sua realização, com mínimas complicações e de utilidade no diagnóstico e estadiamento de pacientes com neoplasia pulmonar.
