title: Changing strategies of lung biopsies in diffuse lung diseases: the impact of video-assisted thoracoscopy.
abstract: The aims of this report were: 1) to compare the strategy of bioptic approach in Italy during the last 4 yrs with a previous period; and 2) to compare efficacy and safety of video-assisted thorascopic lung biopsy (VTLB) versus OLB. We retrospectively evaluated: 1) the strategy of the bioptic approach in the Milan Sarcoid Clinic in the years 1992-1995 (201 patients) versus 1988-1991 (197 patients); and 2) data from 65 VTLB procedures in the years 1992-1995 versus 68 OLB procedures in the years 1988-1991 performed in patients with diffuse lung disease. It was found that the use of OLB (17-9%), mediastinoscopy (15-5%), and scalene node biopsy (20-7%) decreased, whereas transbronchial biopsy (TBB) increased (11-17%). VTLB biopsy is now performed in 17% of patients. VTLB compares favourably with OLB as there is less need for analgesia (7.5+/-7.5 versus 17.5+/-8.0 methadone mg i.m.: p<0.001), lower blood loss (61+/-58 versus 156+/-84 mL in the first postoperative day: p<0.001), and shorter postoperative stay (4.7+/-1.6 versus 5.7+/-1.4 days: p<0.001). Specimen adequacy (98.6 versus 985%) and diagnostic accuracy (86.1% VTLB, versus 92.6% OLB: p>0.05) were the same in the two groups. In conclusion, video-assisted thoracoscopic lung biopsy is replacing both mediastinoscopy and open lung biopsy. It is at present the best option when a surgical procedure is required for histological confirmation of diffuse lung disease.
