To evaluate retrospectively the feasibility and safety of simultaneous multiple microcoil localizations of multiple pulmonary nodules prior to video-assisted thoracoscopic surgery (VATS). This retrospective cohort study enrolled 288 consecutive patients, who underwent computed tomography (CT)–guided microcoil localization and subsequent VATS at our academic hospital between July 2017 and June 2018. Of these patients, 36 with 79 pulmonary nodules undergoing simultaneous multiple microcoil localizations in the ipsilateral lung were designated the multiple localization group; the remaining 252 with 252 pulmonary nodules undergoing single microcoil localization were designated the single localization group. The main outcomes were the technical success and complication rates of the localization procedures. The Student t test and Mann-Whitney U test were used for continuous variables. The chi-squared test and logistic regression analysis were used to assess dichotomous variables. The localization technical success rates of the multiple and single localization groups were 96.2% (76/79) and 98.0% (247/252), respectively (p = 0.326). The rate of any complication (pneumothorax or pulmonary hemorrhage) was significantly higher in the multiple localization than in the single localization group (55.6% vs 21.8%, respectively; p < 0.001). The incidence of pneumothorax was significantly higher in the multiple localization than in the single localization group (p < 0.001). The difference between the incidence of pulmonary hemorrhage in the 2 groups was not significant (p = 0.385). Although preoperative CT-guided simultaneous microcoil localizations of multiple pulmonary nodules produced a significantly higher incidence of pneumothorax, the localizations were clinically feasible and safe. • Simultaneous preoperative CT-guided microcoil localizations of multiple pulmonary nodules are clinically feasible and safe. • Simultaneous microcoil localizations of multiple pulmonary nodules produced a significantly higher incidence of pneumothorax.
