Open lung biopsy for diffuse interstitial lung disease in children

Area of Science:

• Pediatric Pulmonology
• Thoracic Surgery
• Pediatric Pathology

Background:

• Diffuse interstitial lung disease (ILD) in children presents diagnostic challenges.
• Accurate diagnosis is crucial for effective management and prognosis.
• Minimally invasive biopsy techniques may not always provide sufficient diagnostic information.

Purpose of the Study:

• To evaluate the diagnostic contribution of open lung biopsy (OLB) in pediatric diffuse ILD.
• To assess the morbidity associated with OLB in children.
• To compare OLB safety and efficacy with other biopsy techniques.

Main Methods:

• Retrospective review of case notes and histology for pediatric patients (<18 years) undergoing OLB for diffuse ILD between 1991-1998.
• Analysis of procedure-related complications and need for intervention.
• Correlation of histological findings with clinical management changes.

Main Results:

• Open lung biopsy (OLB) achieved a high diagnostic yield (25/27 patients).
• Management plans were altered in 15/27 patients based on OLB results.
• Procedure-related morbidity was low, with only 3/27 patients requiring intervention; most patients were extubated in the operating room without chest drains.

Conclusions:

• Open lung biopsy (OLB) significantly contributes to the management of pediatric diffuse interstitial lung disease.
• OLB demonstrates a favorable safety profile with low morbidity in this pediatric cohort.
• Considering diagnostic accuracy and safety, OLB remains the preferred biopsy technique for pediatric diffuse ILD.
