Abstract:
BACKGROUND:When lung cancer screening work extensively developed in recent years, more and more small lung lesions were found in clinic. The aim of this study is to analysis computed tomography (CT) guided percutaneous biopsy for lung small lesions (diameter<2 cm) on results, complications and prognosis.
METHODS:Choose CT guided percutaneous lung biopsy were performed in 41 cases of pulmonary peripheral lesions, single lesion in 39 cases, multiple lesions in 2 cases, 5-20 (13.1±5.2) mm in maximum diameter, depth from lung surface 1-45 (16.5±13.7) mm, ground-glass opacity (GGO) components 0%-100% (66.8%±35.2%).
RESULTS:41 patients and 43 biopsies successfully obtained pathological tissue. Atypical adenomatous hyperplasia in 3 cases, squamous carcinoma in 1 case, adenocarcinoma in 37 cases( carcinoma in situ in 7 cases, micro-invasive carcinoma in 5 cases, invasive adenocarcinoma in 25 cases, double primary lung cancer in 2 cases), inflammatory lesions in 2 cases. Except 2 cases of inflammatory lesions are in follow-up, biopsy and surgical pathology alignment (specificity) was 100%. 41 patients occurred complications related to percutaneous biopsy. Pneumothorax were in 22 cases, drainage required in 2 cases. There were 17 cases with hemoptysis, accounting for 39.5% incidence are self-limited. Intracranial air embolism occurred in 2 cases by 4.6% incidence. They were fully recovered.
CONCLUSIONS:For small lung lesions, CT guided percutaneous biopsy is technically feasible. However, for small lung lesions especially pure GGO biopsy, it is still need to be cautious.
