[Efficacy of video thoracoscopic lung biopsy in diffuse lung diseases: comparison with open lung biopsy].
The efficacy and safety of video thoracoscopic lung biopsy (VTLB) and of open lung biopsy (OLB) were compared in patients with diffuse lung diseases. Thirty-three patients who had undergone VTLB were retrospectively studied and compared with 67 patients who had undergone OLB. There were no significant differences in age (52.8 +/- 10.9 vs 53.4 +/- 10.3), in the number of biopsies per patient (2.6 +/- 0.6 vs 2.7 +/- 0.6), or in the rate of diagnosis (94% vs 93%) between the two groups. However, the rate of diagnosis was low when the number of VTLB or OLB performed per patient was low. The patients undergoing VTLB had significantly shorter operative times (VTLB, 100.2 +/- 27.2 min. vs OLB, 119.8 +/- 42.6 min; p < 0.01) and less blood loss (VTLB, 4.7 +/- 14.6 ml vs OLB, 65.7 +/- 77.0 ml; p < 0.001). Complications occurred in 3 of the 33 who underwent VTLB, and in 18 of the 67 who underwent OLB. These results indicate that VTLB is an effective and safe alternative in the diagnosis of diffuse lung diseases.
