Transbronchial lung biopsy with fiberoptic bronchoscope

Area of Science:

• Pulmonology
• Thoracic Surgery
• Diagnostic Pathology

Background:

• Diffuse and peripheral lung diseases often require tissue diagnosis.
• Fiberoptic bronchoscopy is a key tool for evaluating these conditions.
• Transbronchial lung biopsy (TBB) offers a minimally invasive method for obtaining lung tissue.

Purpose of the Study:

• To evaluate the diagnostic yield of transbronchial lung biopsy (TBB).
• To assess the safety and complication rate of TBB in patients with diffuse or peripheral lung diseases.
• To determine the utility of TBB in cases without visible endobronchial lesions.

Main Methods:

• Transbronchial lung biopsy (TBB) performed during fiberoptic bronchoscopy.
• Fluoroscopic guidance utilized for all procedures.
• 133 patients with diffuse or peripherally localized lung diseases were included.
• Exclusion criteria included endobronchial lesions.

Main Results:

• Histological diagnosis was achieved in 96 out of 133 patients (72%).
• Specimen inadequacy for evaluation occurred in 4% of cases.
• A diagnosis was not possible in 33 cases despite adequate specimens.
• A low complication rate was observed.

Conclusions:

• Transbronchial lung biopsy (TBB) is an effective diagnostic procedure for select lung diseases.
• Careful patient selection and technique contribute to a low complication rate.
• TBB provides valuable histological information for diagnosing peripheral and diffuse lung conditions.
