Video-assisted thoracoscopic lung biopsy in the diagnosis of diffuse interstitial lung disease. A prospective study.
OBJECTIVE
Video-assisted thoracoscopic lung biopsy is commonly performed for diagnosis of diffuse interstitial lung disease. This study reports our experience with this technique in terms of diagnostic accuracy, complications and appropriate site for biopsy.


METHODS
A prospective non-randomized study.


METHODS
Thoracic Surgery Department, Chest Diseases Hospital, Kuwait.


METHODS
79 consecutive patients undergoing thoracoscopic lung biopsy for diffuse interstitial lung disease from January 1995 to December 2001. Patients were divided into 2 groups; 34 patients with single biopsy from lingula or right middle lobe (RML) and 45 with 2 biopsies from other sites.


METHODS
comparison of operative and postoperative data, diagnostic accuracy, and complications between the two groups.


RESULTS
The mean age of the patients was 38.9 years (range 15-75 years). There was no difference in the groups in operative time, 24 hours postoperative pleural drainage, chest tube drainage days, and hospital stay. Histologic diagnosis was achieved in 76/79 patients (96%). The diagnostic yield of each group was comparable (32/34 from lingula/RML; 44/45 other sites), (p=0.3). Postoperative complications occurred in 4/34 of patients with single biopsy from lingula or RML and 4/45 patients with 2 biopsies from other sites (p=0.6). There was 1 death in this series.


CONCLUSIONS
Video-assisted thoracoscopic lung biopsy is an effective procedure. Single lung biopsy from lingula or RML compared to other anatomic sites has an equivalent diagnostic yield.
