Transbronchial Lung Cryobiopsy
Conditions
Keywords
transbronchial lung cryobiopsy, standardized training, learning curve, bronchoscopist
Brief summary
The aim of this study was to conduct a prospective randomized controlled trial to design simulator and in vitro lung standardized training, to perform a learning curve evaluation of transbronchial lung cryobiopsy (TBLC) operating physicians, and to assess the role of standardized training in TBLC.
Interventions
Simulation training of bronchoscopists by means of simulators and extracorporeal lungs
TBLC training for bronchoscopists through traditional lectures, hands-on demonstrations

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Obtain pathologic quality assessment of specimens | 1 month | The quality of TBLC sampling specimens was scored by two professional pathologists on a specialized pathology scale. |
| histopathological pattern diagnosis rate | 1 month | Diagnosis of histopathological patterns was performed by two specialized pathologists to determine a consistent diagnostic rate. |
| diagnostic rate of multidisciplinary discussions | 1 month | Diagnostic rates based on composite TBLC, BAL, clinical and imaging data in a multidisciplinary discussion by clinical experts |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Occurrence of short-term adverse events | 24 hours or 7 days | bleeding and pneumothorax occurred with 24 hours after TBLC, acute exacerbation of ILD and death occurred with 7 days after TBLC |
