Abstract:
BACKGROUND:Localization of multiple small lung nodules is the technical difficulty of minimally invasive operation resection. However, there are few clinical studies on the preoperative localization of multiple small lung nodules. This study was designed to evaluate the clinical value of preoperative computed tomography (CT) guided microcoil localization for multiple small lung nodules compared with single small lung nodule before video-assisted thoracoscopic surgery (VATS).
METHODS:A retrospective analysis of the clinical data of 235 patients with preoperative pulmonary nodules microcoil localization was performed. According to whether the nodules were single, they were divided into single nodule group (184 cases) and multiple nodules group (51 cases) (multiple nodules group). The single nodule group was positioned under CT-guided conventional methods. The multiple nodules group were CT guided localized by microcoil in batches according to priority before VATS. The success rate, complications, pathological results and localization operations related data were statistically analyzed.
RESULTS:The success rate of localization in multiple nodule groups was 90.2%, there was no significant difference compared with the single nodule group (90.2% vs 94.6%, P=0.205). The occurrence rate of pneumothorax in multiple nodule group and single nodule group was no statistical difference (21.6% vs 14.1%, P=0.179), however, the operation time in the multiple nodule group was significantly longer than the single nodule group [(30.6±6.6) min vs (19.9±7.4) min, P=0.000]. There were no serious complications such as massive hemoptysis, air embolism or hemothorax. There was no conversion to thoracotomy due to failure of localizing the nodules during operation. Sub-lobectomy was the main method of operation. The majority of postoperative pathologies were non-invasive carcinomas.
CONCLUSIONS:For multiple small lung pulmonary nodules requiring thoracoscopic surgery, according to certain strategies, preoperative CT-guided localized by microcoil in batches according to priority before VATS is safe and effective, and worthy of promotion.
