Both positive and negative samples for LC were considered as valid ones while non-representative as not valid ones. Surgical mediastinal biopsy was considered as a gold standard.Results: Seventy-three (14 diagnosis, 56 staging and 3 restaging) procedures were added, accounting for 83 punctures with 80.7% of valid samples (size in mm): 4Lp (7.7), 5 (9.2), 7p (10.3), 8 (10.8), celiac trunk (5.3), left adrenal gland (LGA) (31.9).According to the P’s criteria, same nodes by both EBUS and EUSb were sampled: in 2 cases in 4L (9.5%) and in 1 case in 7 (2.8%) the only valid sample was obtained by EUSb. The agreement (including not valid samples) between both approaches was moderate in 4L (κ 0.479) and good in 7 (κ 0.608).Diagnosis Group: in 3 cases (21%) the EUSb was the only positive result (a lung lesion and 2 LGA punctures which shortened the test).Staging Group: after excluding of the analysis those with no surgical confirmation, we had 11 positive and 23 negatives cases. Mediastinal involvement rate was 32.3%. EUSb never modified EBUS stage. The combined test EBUS+EUSb presented: S 0.92, NPV 0.95 and LR- 0.08. When compared to our historical series of EBUS+EUS (EUS by GE) (S 0.95, NPV 0.88, LR- 0.05), we found similar values.Conclusions: 1. EUS-b is a useful tool in LC diagnosis. 2. In LC staging, the utility of EBUS+EUSb is similar to EBUS+EUS by a P and a GE.FootnotesCite this article as: European Respiratory Journal 2019; 54: Suppl. 63, PA4771.This is an ERS International Congress abstract.
