Lung biopsy in children: when is it useful?

Area of Science:

• Pediatric Pulmonology
• Diagnostic Pathology

Background:

• Lung biopsy is a critical diagnostic tool in pediatric respiratory medicine.
• Assessing the utility of lung biopsy in children is essential for optimizing patient care.

Purpose of the Study:

• To evaluate the diagnostic yield and clinical impact of lung biopsy in pediatric patients.
• To determine the rate of definitive diagnoses and treatment alterations following lung biopsy.

Main Methods:

• Retrospective review of 39 pediatric lung biopsies performed between January 2007 and December 2017.
• Histology results were categorized as definitive diagnosis, normal lung parenchyma, or inconclusive.

Main Results:

• A definitive diagnosis was achieved in 64% of cases, confirming suspected diagnoses in 41% and revealing new diagnoses in 23%.
• Histology was inconclusive in 28% and normal in 8% of cases.
• Treatment was altered in 38% of children based on biopsy findings.

Conclusions:

• Pediatric lung biopsy is valuable, frequently confirming suspected diagnoses and leading to treatment modifications.
• The procedure demonstrated low morbidity and no mortality.
• Inconclusive results in some cases highlight the need for careful patient selection to maximize diagnostic accuracy.
