Abstract
Background and Aims: Currently, bronchoscopic sampling from pulmonary metastases is considered difficult because of negative bronchus sign, and VATS or percutaneous needle biopsy are the first choice. We previously reported new middle-range bronchoscope with large channel (outer diameter 5.1 mm/ inner diameter 2.6 mm/ new BF) can obtain enough tissues with large diameter instrument from peripheral pulmonary lesion. We retrospectively assessed diagnostic utility for pulmonary metastasis using new BF.
Methods: Twenty-four patients with pulmonary metastasis of various cancer who underwent bronchoscopy between March 2013 to March 2015 were enrolled in this study, median age 65 years old (range, 48-82 years), male/ female 12/ 12, median size 23.5 mm (range, 11-64 mm). The used BF was new BF/ current BF (1T260, P260, LF-TP) 17/ 7, used GS was K203 (large)/ K201 (small) 22/2 and TBNA through a guide sheath (GS-TBNA) was performed in 16 cases.
Results: The overall diagnostic yield was 83.3% (20/24), the results for each BF were 93.8% (15/16) in new BF group and 62.5% (4/8) in current BF group, respectively. The EBUS findings prior biopsy was within 7/ adjacent to 14/ invisible 3, but after doing TBNA and biopsy, within 14/ adjacent to 8/ invisible 2 and 7 cases confirmed the improvement of reachability. There were no serious complications.
Conclusions: The combination of new BF and GS-TBNA for pulmonary metastasis improves accessibility and enables sufficient specimen collection. This method can be an effective and safe modality for the sampling of pulmonary metastasis.
