We collected data where samples were taken both via the EBUS-TBNA needle and from waste material from the same node. It was also noted as to which sample contained the most diagnostic material.<br \/>\nResults: 54 EBUSs were performed within the study period. If the waste obtained from both the flushing of the EBUS-TBNA needle and from the flushing of the suction syringe contained anything but clear fluid, the waste was sent to cytology, paired with the EBUS-TBNA needle sample from the same node. 38 patients had samples taken from both waste material and via the EBUS-TBNA needle (47 nodes in total). Malignancy was seen in 26 nodes, granulomata in 9, and no disease seen in 12 (1 insufficient sample, 10 true negatives and 1 false negative). Of the 27 malignant nodes, the EBUS-TBNA needle sample contained diagnostic material in 25 samples (sensitivity 96%). The waste sample contained diagnostic material in 23 samples (sensitivity 85%); in 13 of these, the waste sample was felt to have either as much or more diagnostic material than the sample obtained from the EBUS-TBNA needle.<br \/>\nConclusion: Waste material obtained during EBUS contains diagnostic material in the majority of cases, and in our cohort contained at least as much material as the corresponding EBUS-TBNA needle sample in 50% of samples. This is important when considering the rising amount of tissue required by oncologists for molecular testing.<\/p>\n<p><a href=\"https:\/\/erj.ersjournals.com\/content\/54\/suppl_63\/PA3064\">Link to full-text<\/a> [no password required]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Type of publication: Poster presentation Author(s): *V.
