Abstract
Objectives: To evaluate the effectiveness of track embolization using gelatin sponge torpedo in reducing the incidence of pneumothorax and chest tube placement after percutaneous CT-guided lung biopsy. Methods: A retrospective single-center analysis of percutaneous computed tomography (CT)-guided transthoracic lung biopsies was performed between 2017 and 2022. After excluding the patients who received an ultrasound-guided biopsy, combined lung biopsy with ablation, fiducial placement, unsuccessful procedure due to uncooperative patient, and age under 18 years, 884 patients’ clinical information was collected (667 without track embolization and 217 with track embolization). The incidence of early and late pneumothorax and chest tube placement were compared between the two groups. Propensity score matching (PSM) was applied to minimize selection bias. Univariable and multivariable analyses were performed to determine risk factors for pneumothorax. Results: After PSM, the baseline differences and all factors that could affect the incidence of pneumothorax were balanced between the track embolization group (217 patients) and the non-track embolization group (217 patients). The incidence rates of early pneumothorax (13.4% vs. 24.0% p = 0.005), late pneumothorax (11.0% vs. 18.0% p = 0.021), and chest tube placement (0.9% vs. 4.6% p = 0.036) were significantly decreased in the track embolization group. However, the success rate of tissue diagnosis yield and length of hospital stay were not significantly different between the two groups. In multivariate analysis, the risk of pneumothorax increased as the fissure was passed (OR = 3.719, p = 0.027). Conclusions: Using track embolization with a gelatin sponge torpedo significantly decreased the incidence of pneumothorax and chest tube placement following percutaneous CT-guided lung biopsy.
