简要总结
The purpose of this study is to compare cryobiopsies with forceps biopsies during semirigid thoracoscopy.
详细描述
The investigators are going to compare diagnostic yield and size, morphological features, immunohistochemistry as measures of the quality of the samples. The secondary aim is to evaluate safety with focus on bleeding intensity.

结局指标
主要结局
Comparison of forceps biopsy and cryobiopsy samples
时间窗: 12 month
* diagnostic yield * size of the biopsy specimens in mm2 * interpretability of biopsy specimens in histopathology terms: 1. easily interpretable (enough tissue with all elements required for diagnosis) 2. interpretable with some difficulty (less tissue or diagnostic elements - diagnosis less reliable) 3. interpretable with great difficulty (little tissue or scarce diagnostic elements - low reliability of diagnosis) 4. non-interpretable (diagnosis not possible) * assessment of biopsy-related artifacts by describing the amount of unaltered tissue in quartiles
次要结局
- Safety(1 month)
