Abstract 【Objective】 To explore the feasibility of CT guided percutaneous lung biopsy in the qualitative diagnosis of solitary pulmonary nodules in the country-level hospitals. 【Methods】 A total of 127 patients with solitary pulmonary nodules diagnosed by computed tomography (CT) and CT guided percutaneous lung biopsy in our hospital from May 2016 to June 2021 were retrospectively collected, and the feasibility and diagnostic rate of CT guided percutaneous lung biopsy in primary hospitals were analyzed and summarized. 【Results】There were 127 nodules, including 98 solid nodules, 23 mixed ground glass nodules and 6 pure ground glass nodules. The size of nodules ranged from 1.5 to 3.0 cm, with an average diameter of (2.33±0.25) cm. The success rate of CT guided percutaneous lung biopsy was 100%. 125 cases were confirmed by percutaneous lung biopsy, with a diagnostic rate of 98.43%, including 105 cases of malignant tumors (82.68%), including 60 cases of squamous cell carcinoma, 35 cases of adenocarcinoma, 4 cases of adenosquamous carcinoma, 3 cases of undifferentiated carcinoma, and 3 cases of small cell neuroendocrine carcinoma; There were 20 cases of benign lesions (15.75%), including 9 cases of inflammatory nodules, 8 cases of tuberculosis and 3 cases of fungi; Two cases (1.57%) were not diagnosed. 【Conclusion】CT guided percutaneous lung biopsy has a high qualitative diagnosis rate for solitary pulmonary nodules, and it is simple to operate, minimally invasive, high safety, high success rate and few complications. It is worth popularizing in the country-level hospitals.
