Lung Cancer Clinical Trial
Three-Dimensional Fluoroscopic Guidance During Transbronchial Cryobiopsy
Summary
This study assesses the effectiveness of transbronchial cryobiopsy guided by 3-dimensional fluoroscopy. Transbronchial cryobiopsy is a procedure to collect lung tissue. The main side effect seen after a transbronchial cryobiopsy is pneumothorax (air leaking out of the lung, which may cause a completely or partially collapsed lung). The standard imaging scans used during this procedure are 2-dimensional (like a photo), which can make it difficult for the doctor to know exactly where the biopsy tool is during the procedure. If the exact location of the device is not clear, a patient can be at a higher risk of pneumothorax. Using a 3-dimensional imaging technique may help to decrease the risk of pneumothorax during transbronchial cryobiopsy.
Full Description
PRIMARY OBJECTIVE:
I. To determine if transbronchial cryobiopsy guided by three-dimensional fluoroscopy reduces the incidence of pneumothorax up to 72 hours after transbronchial cryobiopsy.
SECONDARY OBJECTIVE:
I. To describe outcomes of cryobiopsy, need for interventions related to transbronchial cryobiopsy, radiation dose, and any complications or adverse events after transbronchial cryobiopsy guided by three-dimensional fluoroscopy.
OUTLINE:
Patients undergo transbronchial cryobiopsy guided by three-dimensional fluoroscopy. Patients' medical records are also reviewed.
Eligibility Criteria
Inclusion Criteria:
