Summary
Since the traditional radial endobronchial ultrasound guided biopsy technique of solitary pulmonary nodules using the forceps has several shortcomings, the purpose of this study is to investigate a new biopsy technique using the transbronchial cryobrobe
Detailed description
This is a prospective randomized trial to assess diagnostic accuracy and safety of cryobiopsy using two different outer diameters. Included patients are 1:1 randomized to receive forceps biopsy following cryobiopsy with a 1.1mm or 1.7mm cryoprobe.
Conditions
Interventions
| Type | Name | Description |
|---|---|---|
| PROCEDURE | Forceps biopsy and cryobiopsy | Once the nodule is visualized by radial EBUS, the position of the probe in relation to the lesion is noted. Routinely, forceps biopsy and cryobiopsy are used serially in each patient within the same session. |
