Abstract: ob＜x＞jective To explore the feasibility, safety and accuracy of CT guided coil localization combined with abdominal belts for lung nodules in thoracoscopic surgery. Methods One hundred patients with small pulmonary nodules in our hospital from July 2021 to December 2021 were selected retrospectively and randomly divided into the control group and the observation group, with 50 cases in each group. In the control group, me＜x＞tal coil was used to localize lung nodules under the guidance of CT before operation, while in the observation group, coil localization was performed with abdominal belts. The duration of localization, localization success rate, localization complications, nodules resection time and pathologic diagnosis were observed and compared between the two groups. Results The duration of localization in the observation group was significantly shorter than that in the control group (19.62±0.36)min vs. (21.66±0.51)min（P<0.01). The incidence of pneumothorax was 2% in the observation group, which was significantly lower than that in the control group(12%, P=0.09). However, there was no significant difference between the two groups in the wedge resection time, operation success rate and pathologic diagnosis. Conclusions The CT guided coil localization combined with abdominal belts for lung nodules technique is less injury, less pneumothorax rate, convenient, safe, effective, and worthy of clinical promotion to use
