Surgical Lung Biopsy for Interstitial Lung Diseases

Area of Science:

• Pulmonology
• Thoracic Surgery
• Radiology

Background:

• Interstitial lung disease (ILD) diagnosis can be challenging.
• Surgical lung biopsy (SLB) is an invasive procedure used for ILD diagnosis.
• High-resolution computed tomography (HRCT) plays a crucial role in ILD assessment.

Purpose of the Study:

• To answer common clinical questions about the role of SLB in ILD diagnosis and treatment.
• To delineate situations where SLB is diagnostic versus when it can be safely avoided.
• To review the diagnostic utility and complications of SLB and the reliability of HRCT in predicting histopathology.

Main Methods:

• Review of existing literature on SLB and HRCT in ILD.
• Analysis of diagnostic yield and complication rates of SLB.
• Evaluation of HRCT performance characteristics in predicting lung histopathology.

Main Results:

• SLB is valuable when clinical and HRCT findings are inconclusive.
• HRCT chest scans, combined with clinical context, can provide a confident ILD diagnosis in many cases, potentially avoiding SLB.
• Studies on SLB diagnostic utility and complications were reviewed, alongside HRCT reliability data.

Conclusions:

• The decision to perform SLB for ILD should be individualized based on clinical, imaging, and potential diagnostic yield.
• HRCT interpretation is critical for guiding the need for SLB.
• Minimizing invasive procedures like SLB when diagnostic certainty is achieved through non-invasive means is a key consideration in ILD management.
