Abstract

BACKGROUND:

Localizing small pulmonary nodules (SPNs) is a challenge during thoracoscopic resection, but preoperative computed tomography (CT)-guided localization using either cyanoacrylate or hookwire can be helpful. This study compared the safety, efficiency, and operability of the two techniques.

METHODS:

From September 2013 to November 2018, 269 patients (269 SPNs) who underwent preoperative CT-guided SPN localization were enrolled. A propensity-matched analysis, incorporating 13 variables, was performed to control potential selection bias.

RESULTS:

All the patients were divided into two groups: CT-guided cyanoacrylate localization group (Group C, n = 149) and CT-guided hookwire localization group (Group H, n = 120). Eighty-six patients were propensity-matched in each group. All SPNs were successfully removed thoracoscopically, and no conversion was required. Localization-related complications in the two groups were similar, including intrapulmonary focal hemorrhage (p = 0.823), pneumothorax (p = 1.000), or hemoptysis (p = 0.121). For pain assessment and management, the cyanoacrylate localization saw a lower pain score (p < 0.001) and less morphine use (p < 0.001). In Group H, the localization took a significantly longer time (p < 0.001). Covering only the patients in Group C, the sub-analysis found that cyanoacrylate localization on the day before surgery did not compromise the accuracy of intraoperative targeting or increase the incidence of complications, compared with the localization on the day of surgery (all p > 0.05).

CONCLUSION:

Compared to hookwire localization, CT-guided cyanoacrylate localization decreased pain and morphine use and allowed flexible surgical schedules, suggestive of its preferability for the resection of SPNs.
