Detection and Prediction of Clinically Significant Pneumothorax After Image-guided Transthoracic Lung Biopsy

Sponsor: Chinese University of Hong Kong

Summary

Objective: The goal of this study is to evaluate the sensitivity and specificity of the presence of pneumothorax on a 4-hour CXR after image-guided transthoracic lung biopsy (TTLB) for diagnosing subsequent clinically significant pneumothorax. Hypothesis to be tested: The investigators hypothesize that an absence of pneumothorax on CXR at 4 hours can accurately predict an absence of clinically significant pneumothorax at 16 to 20 hours. Design and subjects: This is a prospective, single-centre, diagnostic accuracy study conducted at a tertiary referral centre in Hong Kong. Patients will be recruited if an image-guided TTLB is arranged. Study instruments: CXRs will be performed for patients at different time points. The presence and size of pneumothorax (if any) will be recorded. Outcome: The diagnostic capacity of a 4-hour CXR after image-guided TTLB will be provide evidence regarding the safety and patient selection for same-day discharge.
