CHANGING STRATEGIES OF LUNG BIOPSIES IN DIFFUSE LUNG-DISEASES - THE IMPACT OF VIDEO-ASSISTED THORACOSCOPY

The aims of this report were: 1) to compare the strategy of bioptic ap proach in Italy during the last 4 yrs with a previous period; and 2) t o compare efficacy and safety of video-assisted thorascopic lung biops y (VTLB) versus OLB. We retrospectively evaluated: 1) the strategy of the bioptic approach in the Milan Sarcoid Clinic in the years 1992-199 5 (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 w as found that the use of OLB (17-9%), mediastinoscopy (15-5%), and sca lene 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 98.5%) and diagnostic accura cy (86.1% VTLB, versus 92.6% OLB: p>0.05) were the same in the two gro ups, In conclusion, video-assisted thoracoscopic lung biopsy is replac ing both mediastinoscopy and open lung biopsy. It is at present the be st option when a surgical procedure is required for histological confi rmation of diffuse lung disease.
