Synopsis: Background
Lung lesion biopsy is performed when imaging features suspect potential malignancy or nodule demonstrates continuous growth during subsequent imaging. Routinely, the modality of choice approaching lung nodule is bronchoscopy with its variations such as EBUS (endobronchial ultrasound) or electromagnetic navigation bronchoscopy. It is considered safest method associated to low complication rate although its diagnostic accuracy is as much as 86% and is lower for peripherally located nodules. CT guided lung biopsy in some centers is considered the second line option, especially when bronchoscopy fails. Accuracy of CT guided lung biopsy is over 92%, only complication profile is expressed higher in literature.
Methods
We reviewed recent literature regarding available lung biopsy methods, paying special attention to transbronchial and transthoracic approach and also present our center results of CT guided lung biopsy.
Results
Variating result are present in literature with bronchoscopy and its variations been the safest modality albeit its diagnostic accuracy is inferior comparing to CT guided biopsy. Our center results show CT guided biopsy is accurate in over 90 % of cases and the complication profile is low comparing to those presented in literature.
Conclusion
CT guided lung biopsy is accurate method evaluating lung lesions, though is considered less safe comparing to transbronchial biopsy with the cost of lower diagnostic accuracy. Definite agreement is lacking and the modality of choice depends on local expertise, equipment availability and historical background.
