The effect of lung biopsy on lung function in diffuse lung disease

Area of Science:

• Pulmonary Medicine
• Surgical Pathology

Background:

• Diffuse lung diseases require accurate diagnosis, often involving lung biopsy.
• Surgical techniques for lung biopsy include open procedures and video-assisted thoracoscopy (VATS).
• The impact of these biopsy methods on subsequent lung function is a critical clinical consideration.

Purpose of the Study:

• To compare the effects of open lung biopsy versus VATS biopsy on lung function in patients with diffuse lung disease.
• To assess whether lung biopsy, irrespective of surgical approach, alters lung function compared to non-biopsied patients.

Main Methods:

• Retrospective study of 116 patients with diffuse lung disease.
• Patients were categorized into three groups: open lung biopsy (35), VATS biopsy (33), and no biopsy (48).
• Lung function tests were performed pre- and post-procedure or at 3-6 month intervals for the non-biopsy group.

Main Results:

• No significant differences in lung function changes were observed between patients who underwent biopsy (open or VATS) and those who did not.
• The proportion of patients experiencing lung function improvement or deterioration was similar across all groups.
• Subgroup analyses in older patients, those with severe disease, and those with fibrosing alveolitis mirrored the overall findings.

Conclusions:

• Lung biopsy, whether performed via open or VATS approach, does not have a deleterious effect on lung function in the diagnosis of diffuse lung disease.
• Both open and minimally invasive lung biopsy techniques are safe concerning lung function outcomes.
• Diagnosis of diffuse lung disease via biopsy is a safe procedure regarding lung function preservation.
