Diagnostic bronchoscopy: state of the art

Abstract

Since the introduction of the flexible fibreoptic bronchoscope in the late 1960s there have been relatively few technological advances for three decades, aside from the development of a white light video bronchoscope with a miniature charge-coupled device built in its tip replacing the fibreoptics. White light flexible videobronchoscopy with its ancillary devices (forceps biopsy, bronchial brushing, bronchoalveolar lavage, bronchial washings and transbronchial needle aspiration) has long been the only established diagnostic bronchoscopic technique. With the advances in microtechnology over the past two decades, recent technical developments such as autofluorescence bronchoscopy and endoscopic ultrasound allow better evaluation of endobronchial, mediastinal and parenchymal lesions.

Una mirada general a las enfermedades pulmonares intersticiales y una específica a la fibrosis pulmonar idiopática

“…Así la decisión de realizar una BTB, en ausencia de un diagnóstico clínico-radiológico de certeza, depende de las característi-cas del paciente (edad, estado funcional) y de la sospecha diagnóstica. El rendimiento diagnóstico de la BTB dependerá de la distribución topográfica y de la especificidad morfoló-gica de la lesión 1,15 . La BTB tiene una alta rentabilidad en el diagnóstico de sarcoidosis, linfangitis carcinomatosa, daño alveolar difuso, algunas infecciones, proteinosis alveolar y neumonía eosinofílica; rentabilidad moderada en algunas vasculitis, amiloidosis, histiocitosis X o LAM y una baja rentabilidad en el diagnóstico de las NII (con excepción de la NOC), la bronquiolitis constrictiva o enfermedad pulmonar veno oclusiva 1,16 .…”

Bronchoscopy and the peripheral nodule in the age of lung cancer screening and targeted therapies

“…Although initial reports suggested that cytological samples were inadequate [16], recent findings have shown that minimally invasive techniques might be sufficient [17][18][19], [20•]. Rapid on-site evaluation (ROSE) in the bronchoscopy suite may be instrumental in such cases in order to guarantee that the sample obtained is adequate for both a diagnosis and mutation analysis in the majority of cases.…”

Métodos De Biópsia Pulmonar Empregados No Hospital Universitário De Santa Maria: Acurácia, Sensibilidade E Especificidade

“…É uma ferramenta diagnóstica inestimável para muitas desordens pulmonares, sendo considerado um procedimento de baixa morbidade (0,1-2,5%) e muito baixa mortalidade (<0,05%) 2,3 . O termo biópsia endobrônquica (BE) ou biópsia brônquica engloba a análise microscópica de lesões endobrônquicas ou da mucosa brônquica.…”
