NCT05046093 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 50

Last updated 2025-06-03

No results posted yet for this study

Summary

As the former radial endobronchial ultrasound (R-EBUS) guided transbronchial forcep biopsy of peripheral pulmonary nodules has some limitations, the purpose of this study is to investigate a novel biopsy technique, transbronchial cryobiopsy, in patients with peripheral pulmonary nodules.

Conditions

  • Lung Nodule

Interventions

DIAGNOSTIC_TEST

Transbronchial cryobiopsy

When the lung nodule is visualized by thin bronchoscope (4mm) with R-EBUS, cryobiopsy is performed. If not visualized, ultrathin (3mm) bronchoscope is used. Cryobiopsy is performed with 1.1mm cryo-probe.
