简要总结
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
详细描述
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.
