Clinical volue of percutaneous US-guided lung biopsy in peripheral lung lesions

Objective To study the clinical value of US-guided lung biopsy for determining qualitative diagnosis of peripheral lung lesions.Methods Percutaneous US-guided lung biopsy was performed in 80 cases of peripheral lung lesions that had been found by pulmonary imaging examination and needed to be confirmed.Results Successful procedures were performed in the 80 cases (with a successful biopsy rate of 100% ) .The outcomes of pathological diagnosis were listed as follow:64 cases of malignant tumor,including squamous carcinoma (n=38) ,adenocarcinoma (n=20) ,big cell cancer (n=2) ,small cell cancer (n=2) , malignant lymphoma (n=1) and malignant mesothelioma (n=1) ; 16 cases of benign tumor,including benign hamartoma (n=1) , tuberculosis (n=8) and pulmonary infection (n=7) .Complications occurred in 3 cases (3% ) ,including one case of pneumotho-rax and one case of hemoptysis.Conclusion Percutaneous US-guided lung biopsy is easy to perform with accuracy,safety, repeatability and low complications.It's the preferred method of qualitative diagnosis to peripheral lung lesions.
