Do immunocompromised children benefit from having surgical lung biopsy performed?

Area of Science:

• Pediatric Pulmonology
• Pediatric Surgery
• Pediatric Critical Care

Background:

• Surgical lung biopsy is the gold standard for diagnosing pulmonary disease in immunocompromised children.
• Existing literature shows variable accuracy and complication rates for this procedure.

Purpose of the Study:

• To assess the diagnostic and therapeutic yield of surgical lung biopsies in immunocompromised children with persistent pulmonary findings.
• To identify any preoperative factors influencing biopsy outcomes.

Main Methods:

• Retrospective review of clinical records for immunocompromised children who underwent surgical lung biopsy.
• Analysis of patient demographics, underlying immunodeficiencies, and biopsy outcomes.

Main Results:

• Twenty-seven surgical lung biopsies were performed on 25 immunocompromised children.
• A specific diagnosis was achieved in 37% of biopsies; only 18% provided patient benefit.
• The procedure had a low complication rate (4% major complications).

Conclusions:

• Surgical lung biopsy in pediatric immunocompromised patients is a safe procedure.
• The diagnostic yield is relatively low, and the yield for patient benefit is even lower.
• Current preoperative factors do not predict a diagnostic biopsy.
