Técnicas fibrobroncoscópicas especiales: lavado broncoalveolar, biopsia bronquial y biopsia transbronquial

2005

Este artículo completa las recomendaciones sobre el uso y aplicaciones del broncoscopio flexible en la infancia, del Grupo de Técnicas de la Sociedad Española de Neumología Pediátrica, incluyendo los procedimientos que, con fines diagnósticos y ocasionalmente terapéuticos, se aplican con mayor frecuencia durante la práctica de la broncoscopia flexible: el lavado broncoalveolar y las biopsias bronquial y transbronquial. Se realizan también recomendaciones para la práctica del lavado broncoalveolar no broncoscópico.Se revisan las indicaciones, contraindicaciones, recursos materiales, el cuidado y monitorización del paciente previo, durante y posterior al procedimiento, y las complicaciones de…

Utility of laser microdissection and pressure catapulting in the diagnosis of non small cell lung cancer: Preliminary data

2014

Background: There are controversies about the adequacy of tumor tissue sample on which the sequencing of molecular diagnosis could be performed to achieve the targeted-therapy on lung cancer. The aim of this study is to demonstrate the role of the Laser Microdissection Pressure Catapulting (LMPC) technique to obtain adequate tumor tissue sample for the molecular analysis of gene mutations in the target therapy of lung cancer. Findings: From a consecutive series of 24 patients with a diagnosis of locally-advanced or metastatic Non Small Cell Lung Cancer (NSCLC), we performed 29 diagnostic procedures using the system of LMPC, to obtain an homogeneous samples where it was possible to run the s…

Das chemotaktische Verhalten von Alveolarmakrophagen und Blutmonozyten nach Expositionen mit unterschiedlichen NO2-Konzentrationen

2008

The chemotaxis of alveolar macrophages (AM) and blood monocytes (BM) is important in the elimination of particles and microorganisms which have invaded the lung. The effect of nitrogen dioxide (NO2) on chemotaxis was tested on AM obtained by diagnostic bronchoscopy from five patients suspected of having bronchial carcinoma (four men, one woman; mean age 59 +/- 10 years). Blood monocytes were also studied with blood from seven healthy subjects (five men, two women; mean age 32 +/- 10 years). These cells were placed on polycarbonate membranes for 15 min each, exposed to NO2 concentrations between 1.0 and 5.0 parts per million (ppm), and then incubated with complement component C5a as chemotac…

Post-bronchoscopy fatal endobronchial hemorrhage in a woman with bronchopulmonary mucormycosis: a case report

2010

Abstract Introduction During infection, Mucorales fungi invade major blood vessels, leading to extensive necrosis, and in cases of extensive pulmonary disease, bleeding into the lungs may occur. Case presentation We report an unexpected event of post-bronchoscopy fatal endobronchial hemorrhage in a 62-year-old HIV-negative Italian woman with well controlled diabetes mellitus who presented with diffuse cavitated pulmonary lesions. Fiberoptic bronchoscopy revealed bilateral obstruction of the segmental bronchi. Fatal massive bleeding occurred after standard biopsy procedures. Histologic examination showed that the hyphae were more deeply colored by hematoxylin-eosin (H&E) than by other stains…

A rare case of pedunculated bronchial hemangioma

2009

We describe a rare case of pedunculated endobronchial hemangioma observed in a 60 years old patient complaining of chronic productive cough and accessional dyspnea which had been progressively worsening over 20 years. The lesion was first noticed at fiberoptic bronchoscopy; then computed tomography scan was performed and integrated with tridimensional reconstruction techniques. Pathology showed the picture of a vascular neoplasm, compatible with capillary hemangioma. The lesion was submitted to laser-assisted endoscopic removal in order to relieve the obstruction, leading to remission of symptoms.

Development and evaluation of 3-dimensional printed models of the human tracheobronchial system for training in flexible bronchoscopy.

2017

OBJECTIVES Training and assessment of proper skills in flexible bronchoscopy are major educational goals for cardiothoracic residents. Therefore, we developed 3-dimensional (3D) printed models of the human tracheobronchial system for training and assessment of cardiothoracic residents in flexible bronchoscopy. METHODS Three models of normal (size/shape) human tracheobronchial anatomy were generated using a commercially available 3D printer. Ten residents (inexperienced: Group 1; experienced: Group 2) participated in this study with an experimental setting of initial assessment (Model 1), training (15 min, Model 2) and post-training assessment (Model 3). The time needed for flexible bronchos…

Fatal Pulmonary Hemorrhage Through Fiberoptic Broncoscopy in a Well Controlled Diabetic Female With Mucormycosis

2008

A rare case of invasive pulmonary mucormycosis complicated by fatal massive haemoptysis through bronchoscopy in a patient with a well controlled diabetes is reported. Histological features of infection are reported and the characteristic aspects of the staining are discussed. Fiberoptic bronchoscopy revealed bilateral obstruction of the segmental bronchi and fatal massive bleeding occurring because of biopsy sampling. Caution is warranted in the use of bronchoscopy sampling in patients with radiological features of cavitated lesions of fungal origins. Better preventive and early therapeutic antifungal treatments are needed to avoid this serious complication.

Virtual bronchoscopy in patients with central endobronchial stenosing lesions. Technique optimisation with single slice spiral CT.

2004

PURPOSE: To describe an original protocol for single slice spiral Computed Tomography (CT) virtual bronchoscopy in the evaluation of patients with central airway stenoses and compare the results with fibreoptic bronchoscopy. MATERIALS AND METHODS: Ten patients (4 female and 6 male; age range 22-60 years; mean age 44 years) with endobronchial disease diagnosed by fibreoptic bronchoscopy (8 malignant tumours, 1 benign tumour and 1 fibroid stenosis) underwent virtual bronchoscopy with single slice spiral CT. A panoramic spiral CT scan of the whole chest was first obtained. Once the area of interest had been identified, a new contrast enhanced scan was performed, from bottom to top, with the fo…
