Background:
Electromagnetic navigation bronchoscopy is a tool that can accurately navigation peripheral lung lesions. Because of electromagnetic navigation bronchoscopy (ENB) is too expensive, it has not been widely used in China. It is urgent for us to summarize experience in clinical application, especially in the diagnosis of pulmonary nodules.
Methods:
The clinical data of patients with pulmonary peripheral lesions (PPLs) in our department undergoing ENB biopsy between July 2017 and December 2018 were retrospectively analyzed.
Results:
There were 18 patients with 21 PPLs (10 males and 8 females). Among them, 11 patients got the final pathological diagnosis, 8 cases were diagnosed with adenocarcinoma lung cancer, 1 case was diagnosed with tuberculosis and 2 cases were diagnosed with small cell lung cancer. The positive rate of diagnosis was 61.1%. The sensitivity was 73.3%. The positive diagnosis rate is related to the size of the lesion, the positive diagnosis rate for lesions >2 cm is 100.0% (P=0.04).
Conclusions:
Electromagnetic navigation bronchoscope is safe and effective in clinic. It has a high positive rate for the diagnosis of peripheral lung lesions larger than 2 cm, ENB has broad clinical application prospects.
