Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 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. | — |
Secondary
| Measure | Time frame |
|---|---|
| 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.). | — |
