Radial-EBUS: CryoBiopsy Versus Conventional Biopsy: Time-Sample and C-Arm.

INTRODUCTION

Diagnosis of lung nodules is still under investigation. We use computed tomography scans and positron emission tomography in order to identify their origin.

PATIENTS AND

METHODS

In our retrospective study, we included 248 patients with a single lung nodule or multiple lung nodules of size ≥1 cm. We used a radial-endobronchial ultrasound and a C-Arm. We used a 1.1 mm cryoprobe versus a 22G needle vs. forceps/brush. We compared the sample size of each biopsy method with the number of cell-block slices.

RESULTS

Central lesions indifferent to the method provided the same mean number of cell-block slices (0.04933-0.02410). Cryobiopsies provide less sample size for peripheral lesions due to the higher incidence of pneumothorax (0.04700-0.02296).

CONCLUSION

The larger the lesion ≥2 cm, and central, more cell-blocks are produced indifferent to the biopsy method (0.13386-0.02939). The time of the procedure was observed to be less when the C-Arm was used as an additional navigation tool (0.14854-0.00089).
