ABSTRACT
Objective To evaluate the diagnostic value of transbronchial lung biopsy (TBLB) in pediatric interstitial lung diseases.Methods Retrospective data evaluation the efficacy and application of 10 undiagnosed pediatric interstitial lung diseases patients by No-X-ray guided TBLB between December 2013 and December 2014 were investigated.Results Specimens from all cases were successfully obtained,6 patients were confirmed by pathological diagnoses,and4 patients were confirmed by pathology and clinical manifestations.Among 10 patients,3 of them had allergic alveolitis,2 cases had bronchiolitis obliterans organizing pneumonia (BOOP),1 had pulmonary vasculitis,2 cases had nonspecific interstitial pneumonia,and the other 2 had bronchiolitis obliterans.The complications include 2 pneumothorax,1 case was cured with thoracic cavity closed drainage,and the other case case did not receive special treatment and alleviated himself.No bleeding and other complications occurred.Conclusion The results suggest that TBLB is a safe and effective minimally invasive modality for the diagnosis of pediatric diffuse lung disease.
