TBNA is an established method for diagnosing mediastinal lymphadenopathy and staging of lung cancer. EBUS guidance seems to be beneficial in increasing the diagnostic yield. The auim of the present study was to gain experience with a new method of bronchoscopic ultrasound with direct, real time guided transbronchial needle aspiration.
Consecutive patients referred for TBNA of mediastinal lymph nodes were encluded in the trial. After detection of the node a ultrasound real time controlled puncture was performed. The results were compared to operative findings. Lymph node stations were classified after the recent ATS scheme.
214 patients (63 female, 151 male, mean age 53.9 years, range 22-79) were examined. Targeted were the lymphnodes region 2l, 3r, 3, 4r, 4l, 5, 7, 10r, 10l, 11r and 11l. The overall yield for was 89%. No complications were seen.
EBUS TBNA is a promising new technique for lymph node staging. The yield increased to conventional TBNA.
EBUS guidance should be considered as a routine adjunct to TBNA.
