transbronchial biopsy(English)

• technique by which a piece of lung parenchyma is obtained by using flexible forceps positioned distally via FB. Specimens can be obtained blindly or with guidance by fluoroscopy, computed tomography, or radial-probe endobronchial ultrasonography. In many instances it can obviate the need for an open-lung biopsy; however, certain diagnoses such as idiopathic pulmonary fibrosis generally require larger tissue samples than those that can be obtained bronchoscopically. Diagnostically useful in 38% to 79% of patients (average sensitivity, 52%), depending upon the underlying disease
