Bronchoscopic Lung Biopsy With Fluoroscopy to Study 164 Localized Pulmonary Lesions

Multivariate study of predictive factors for clearly defined lung lesions without visible endobronchial lesions in transbronchial biopsy

“…Although there are several techniques that permit a guided cytological or histological diagnosis (aspiration, puncture, and biopsy) of peripheral pulmonary lesions with no evidence of endobronchial lesions (ultrafine FB, endobronchial ultrasound, electromagnetic navigation) [1, 2, 10-12], fluoroscopy is probably still the most widely used technique because it is more readily available [3][4][5][6][7][8][9][13][14][15]. Although it is possible to use many devices, such as biopsy needles, brushes, and forceps singly or in combination, to obtain this diagnosis, TBB is almost certainly the most widely used technique.…”

“…TBB is also the technique that has been the subject of the greatest number of studies, looking at both cost-effectiveness and predictors [3-9, 13-15]. The sensitivity described in the literature varies from 17 to 77% [3][4][5][6][7][8][9]; this variability is due to differences in the nature and size of the lesions, their localization, and probably the experience of the endoscopists. Notably, several published series include patients who demonstrate at least indirect signs of endobronchial lesions [6,8].…”

“…Lesion localization was defined according to the lobe in which it was situated and the distance from the pulmonary hilum. Localization was accomplished, as in previous studies [6][7][8][9], by dividing the area around the hilum on the CT scan into three elliptical regions: central (ellipse in the internal third), intermediate (ellipse in the middle third), and peripheral (ellipse in the external third). When the lesion occupied more than one ellipse, it was assigned to the area containing most of the lesion.…”

Rendimiento diagnóstico de la broncoscopia con biopsia transbronquial en el estudio de lesiones sugerentes de cáncer pulmonar

“…En nuestra serie, destaca en especial la presencia de una neoplasia previa en 18% de los pacientes y las lesiones focales encontradas como hallazgos radiológicos, sin sintomatología asociada 4,5 .…”

A randomised trial of endobronchial ultrasound guided sampling in peripheral lung lesions

“…Figure 15 The papers included in Figure 15 Lesions had to be visible by fluoroscopy in one report (115), other reports included only small lesions below 3 cm (61;76;108;127;128;131). These selections might have influenced the diagnostic yields.…”
