Pulmonary nodules localization via microcoil and anchor with scaled suture guided by CT in thoracoscopic surgery:A retrospective cohort study

Objective To compare the effectiveness and safety of preoperative lung localization by microcoil and anchor with scaled suture.Methods A total of 286 patients underwent CT-guided puncture localization consecutively between October 2019 and December 2020 in our hospital.According to the different methods of localization,they were divided into a microcoil group(n=139,including 49 males and 90 females,aged 57.92±10.51 years)and an anchor group(n=147,including 53 males and 94 females,aged 56.68±11.31 years).The clinical data of the patients were compared.Results A total of 173 nodules were localized in the microcoil group,and 169 nodules in the anchor group.The localization success rate was similar in the two groups.However,the anchor group was significantly better than the microcoil group in the localization time(8.15±2.55 min vs.9.53±3.08 min,P=0.001),the pathological receiving time(30.46±14.41 min vs.34.96±19.75 min,P=0.029),and the hemoptysis rate(10.7%vs.30.1%,P=0.001),but the pneumothorax rate was higher in the anchor group(21.3%vs.11.0%,P=0.006).Conclusion Preoperative localization of small pulmonary nodules using anchor with suture is practical and safe.Due to its simplicity and convenience,it is worth of promotion in the clinic.
