ABSTRACT
INTRODUCTION:
Electromagnetic navigation (ENB) is a guidance tool used in the diagnosis of solitary pulmonary nodules (SPNs) and masses. Its diagnostic yield is highly variable (38-71%) and a recent study has put in doubt the role of ENB in sampling SPNs in a real-life setting. The aim of this study is to describe the 5-year experience of our center with ENB, analyzing the population, possible confounding factors, and the diagnostic yield and accuracy of this technique.METHODS:
We conducted a retrospective observational study including all consecutive patients who underwent ENB for SPNs and masses from January 2011 to December 2015.RESULTS:
We included 113 patients; 79% had SPNs, 21% masses. The majority were localized in the upper and middle lobes (80%) and 61% presented a bronchus sign. 54% of the patients had a previous negative fluoroscopy-guided bronchoscopy. ENB achieved the diagnosis in 78 patients (69%) with 64 malignant and 14 were benign lesions. The diagnostic yield and accuracy of ENB were respectively 0.69 and 0.76. The only factor influencing the ability to reach a diagnosis was the presence of bronchus sign (p = 0.002). No procedural complications were reported.CONCLUSION:
ENB is a safe procedure with a similar diagnostic yield in the real-life and research setting. Bronchus sign is an important factor in determining the diagnostic yield. ENB efficacy can be maximized by expertise and by a careful selection of each case.Palabras clave
