Image-guided percutaneous approach is superior to the thoracoscopic approach in the diagnosis of pulmonary nodules in children

Abstract

Background/purpose: Image-guided, percutaneous techniques are increasingly used in diagnosis of pulmonary disease in children. The aim of this study was to determine the diagnostic accuracy and clinical outcomes of thoracoscopic versus percutaneous lung biopsy in children.

Methods: Sixty-three consecutive patients from January 1996 to December 2000 who had a thoracoscopic lung biopsy, a percutaneous ultrasound scan, or computed tomography (CT)-guided lung biopsy for well-defined and ill-defined lesions were analyzed.

Results: Twenty-eight patients had a thoracoscopic lung biopsy (TLB), and 35 patients had a percutaneous image-guided lung biopsy (PLB). Age ranged from 6 months to 17 years (median, 8 years). There was no significant difference between groups with regard to age, depth of lung nodule biopsied, or prebiopsy diagnoses. Seventeen patients (60%) of TLB and 23 (65%) of PLB had well-defined pulmonary nodules suspicious for malignancy at the time of biopsy. Adequate tissue for pathologic diagnosis was obtained in 28 (100%) of TLB versus 26 (80%) of PLB patients. However, 8 (28%) thoracoscopic cases needed to be converted to an open procedure. In 3 (8.5%) PLB cases the percutaneous biopsy was insufficient, and a thoracoscopic or open biopsy was required. The median hospital stay was 3 days for TLB and 4 to 6 hours for PLB (P =.023). There were no complications in the PLB group. Five (18%) of TLB patients suffered a persistent air leak treated with continued chest tube drainage, and one patient died of other causes with a persistent air leak.

Conclusions: Percutaneous lung biopsy has a significantly shorter hospital stay and a lower complication rate than thoracoscopic lung biopsy. The authors propose that the percutaneous technique should be considered as the initial approach for children with pulmonary nodules.
