Purpose : Recent advances in imaging modalities and recommended low dose CT screening program made it easier to diagnose early lung cancer. Because of low diagnosis yields of conventional diagnostic procedure, we have to surgical biopsy for ground glass nodules that highly suspected malignancy. The purpose of this study was to evaluate the usefulness of Electromagnetic Navigation Bronchoscopy(ENB) for intraoperative localization of pulmonary GGNs.
Methods : From 2017 to 2019, 110 cases of suspicious lung cancer lesions that were not diagnosed by conventional procedure such as transbronchial or percutaneous approach were undergone ENB-guided lung resection. Among them, 35 cases of GGNs were included in this study. We used SuperDimension™ for ENB procedure.
Results : Among 35 GGNs, 17 lesions were pure GGNs and 18 lesions were mixed GGNs. The mean size of all lesions was 12 mm(IQR : 7-16mm), the mean distance to pleura was 7 mm(IQR : 0-15mm) and the mean procedure time was 19 minutes(IQR : 10-28). Overall success rate of ENB procedure for detection of pulmonary GGNs was 94.3%. There was no procedure related complication. Seventeen cases of pure GGNs, there were two adenocarcinoma in situ(AIS), two atypical adenomatous hyperplasia(AAH), five minimally invasive adenocarcinoma(MIA), two invasive carcinoma, one metastatic carcinoma and five benign lesions. Among eighteen cases of mixed GGNs, there were one minimally invasive adenocarcinoma(MIA), ten invasive carcinoma, two metastatic carcinoma and five benign lesions
Conclusion : Success rate of ENB procedure for small GGNs was high with no complication. Electromagnetic Navigation Bronchoscopy(ENB) can be used for accurate localization of small GGNs.
