RESUMEN
One hundred and forty patients underwent 142 brushings and conventional biopsies of suspected malignant lesions of the lung through a fibreoptic bronchoscope. Both samples were taken from the same area. One hundred and three patients showed positive results on brushing and 90 on biopsy. Thirty-nine diagnoses were negative on brushing and 52 on biopsy. A correct cell typing was obtained in 105 of 109 diagnoses of malignancy. Final diagnoses showed 118 malignant lesions and 22 benign conditions. False positives were respectively, 2 on brushing and 1 on biopsy, while false negatives were 17 on brushing and 30 on biopsy. Brushing showed higher sensitivity (85.5%) and accuracy (86.6%) than biopsy. A combination of the two techniques gives an accuracy rate of 94.3%.

An experimental study on tracheal reconstruction using a jejunal loop autograft, is reported. Eight dogs divided into 2 groups have been used. In the first group the jejunal loop was prepared using a single vascular pedicle including both the artery and the vein and was revascularized with the superior thyroid artery and its collateral vein. In the second group the jejunal loop was prepared with two different vascular pedicles, revascularizing the artery with the superior thyroid artery and the vein with the jugular vein. In this group a sylastic T-tube was placed inside the loop. The procedure and preliminary results, are reported.
