ABSTRACT
Objective:To investigate the application value of CT-guided localization with medical glue or puncture needle before thoracoscopic pulmonary ground-glass nodule resection.Methods:The clinical data of 92 patients who underwent localization before thoracoscopic resection of pulmonary ground-glass nodules in Beijing Chao-Yang Hospital from June 2019 to November 2022 were retrospectively analyzed. According to the preoperative localization method, the patients were divided into puncture needle group (52 cases) and medical glue group (40 cases). The localization success rate, localization time and incidence rate of complications were compared between the two groups.Results:The success rate of localization in both groups was 100%. In puncture needle group, the guide wire of 1 case (1.9%) prolapsed, but it did not affect the surgical resection. The localization time of puncture needle group and medical glue group was (18±6) min and(14±5) min, and there was a statistical difference between the two groups ( t = 3.06, P = 0.003). The incidence of bleeding and pneumothorax in medical glue group was lower than that in puncture needle group [12.5% (5/40) vs. 38.5% (20/52), χ2 = 7.70, P = 0.009; 35.0% (14/40) vs. 71.2% (37/52), χ2 = 11.96, P = 0.001]. The incidence rate of irritating cough in was higher than that in puncture needle group [50.0% (20/40) vs. 11.5% (6/52), χ2 = 16.50, P < 0.05]. Conclusions:CT-guided localization with medical glue or puncture needle can achieve satisfactory results in the localization of pulmonary ground-glass nodule before thoracoscopic resection and help to improve the accuracy of surgical resection. The incidence rates of bleeding and pneumothorax of medical glue localization are lower than those of puncture needle localization.
