Flexible transbronchial needle aspiration for staging of bronchogenic carcinoma.
Flexible transbronchial needle aspiration (TBNA) provides access to mediastinal lymph nodes, but its role in staging bronchogenic carcinoma is unknown. To determine the efficacy and safety of this procedure for staging the extent of mediastinal disease, the results of TBNA performed during fiberoptic bronchoscopy in 39 patients without known extrathoracic metastases were reviewed. Flexible TBNA...
متن کاملTransbronchial Needle Aspiration in the Staging of Bronchogenic Carcinoma
To evaluate the usefulness of transbronchial needle aspiration biopsy (TBNA) for the diagnosis of mediastinal involvement, we have prospectively examined 316 patients with morphologically verified bronchogenic carcinoma. The percentage of positive aspirations (149 of 316) from the three basic lymph node groups in the mediastinum was not significantly different. Tumor cells were aspirated from t...
متن کاملTransbronchial fine needle aspiration of bronchogenic cysts.
Transbronchial fine needle aspiration (TBFNA) was used to confirm the diagnosis of bronchogenic cyst in two asymptomatic patients with mediastinal masses who declined surgical exploration. Both masses were located subcarinally but differed in computed tomographic density (7 and 59 Hounsfield units). Aspirate cytology demonstrated predominately bronchial columnar epithelial cells in mucus, witho...
متن کاملA new versatile transbronchial cytology needle for the staging and diagnosis of bronchogenic carcinoma.
A new versatile transbronchial needle, the modified type 2B retractable needle, was used for the staging and diagnosis of bronchogenic carcinoma. It combines the advantages of its predecessors, the fixed type 1A needle and the retractable type 2A needle, such as convenience of usage and the added ability to sample peripheral as well as central lesions. The new modified type 2B retractable needl...
متن کاملTransbronchial needle aspiration in the diagnosis of submucosal and peribronchial bronchogenic carcinoma.
Although exophytic endobronchial lesions can readily be diagnosed by routine forceps biopsy through the fiberoptic bronchoscope, submucosal or peribronchial tumor can be difficult to diagnose with nonsurgical techniques. We evaluated the utility of transbronchial needle aspiration (TBNA) through the fiberoptic bronchoscope in 31 patients presenting with endoscopic abnormalities suggestive of su...
