Objectives
Narrative objectives1
Sputum examination and the bronchoscopic technique may be performed in an attempt to diagnose pulmonary thin-walled cavitary lesions. However, in our experience, a diagnosis cannot always be established in these lesions by sputum examination or the bronchoscopic technique, and surgical biopsy is occasionally needed, which is a highly invasive method. Millard and Westcott reported a method of percutaneous needle washing for the diagnosis of cavitary lesions of the lung, in which normal saline is injected into the cavity and then aspirated (Radiology 1974;111:474). We aim to ascertain the diagnostic significance and the safety of percutaneous needle washing method in the diagnosis of pulmonary thin-walled cavitary lesions.

Assessment
Primary outcomes
The specimen obtained by percutaneous needle washing method is analyzed by cytological and microbiological examinations. Sensitivity and specificity of this method in the diagnosis of pulmonary thin-walled cavitary lesions is observed. The final diagnosis of each patient is confirmed by either surgery or clinical follow-up of more than one year.
Key secondary outcomes
The clinical observation of more than one year after the procedure for each patient is required to monitor the potential complications of percutaneous needle washing method; short-term complications (pneumothorax, hemoptysis, cough, air embolism, etc.) and long-term complications (invasion of the cancer, spread of the infection, etc.).
