title: Thoracoscopic biopsy in children with diffuse parenchymal lung disease.
abstract: Lung biopsy is necessary for establishing the diagnosis in patients with otherwise unclassified diffuse or localized parenchymal lung disease. This study aimed to assess the safety and accuracy of video-assisted thoracoscopic (VATS) lung biopsy in children with diffuse parenchymal lung disease (DPLD). In addition we aimed to evaluate the value of this technique with respect to the spectrum of diseases encountered, correlating histological diagnosis with treatment decisions and subsequent clinical outcome. Data from all patients (n = 21) who underwent surgical lung biopsy for suspected DPLD between March 2001 and August 2006 were collected prospectively. Median age was 3 years, 8 months (range 11 days to 15 years, 2 months). All lung biopsies were performed by VATS under general anesthesia. Median operative time was 45 min (range 25-100 min). Conversion to minithoracotomy due to cardiorespiratory difficulties was necessary in two young infants. There were no further intraoperative complications. In 8/21 children, a chest tube was inserted postoperatively for a median of 2 days (range 1-5 days). In one patient, prolonged air-leakage was managed thoracoscopically on postoperative day 9. There were no other postoperative complications. The specimens were of adequate volume and quality and a histopathological diagnosis was obtained for all patients. There was a broad spectrum of different diagnoses which led to specific therapeutic decisions. Subsequent medical treatment was beneficial in the majority of the patients. In conclusion, VATS is a safe and effective procedure for diagnosis of children with suspected DPLD. Diagnostic accuracy is high, morbidity rates are low, and patients may benefit from avoiding thoracotomy.
