PURPOSES: This study aimed to describe a new localization technique developed using an anchor with a scaled suture (AWSS) system and to characterize the localization results and post-operative outcomes to evaluate its safety and effectiveness.
METHODS: This retrospective study was conducted at our centre from October 2020 to December 2021. In total, 328 small pulmonary nodules (sPNs) who underwent pre-operative computed tomography (CT)-guided AWSS system localization followed by wedge resection by video-assisted thoracoscopic surgery (VATS) were enrolled in this study.
RESULTS: CT-guided AWSS system implantations targeting 328 sPNs were successfully performed. The time spent performing localization was 12.4 ± 4.9 min. After puncture localization, the incidences of pneumothorax, pulmonary haemorrhage, and chest pain were 19.2% (63/328), 25.9% (85/328), and 0.9% (3/328), respectively. The incidence of overall complications was 42.7%. According to the CIRSE classification, there were no major complications. The median localization-VATS interval time was 7 h (range, 1-75 h). In 328 cases (100%), the location of the lesion was determined by palpation of the four-paw anchor in the lung and was successfully resected by VATS, and the correct diagnosis was obtained.
CONCLUSION: In this series, CT-guided pre-operative localization of pulmonary nodules with the AWSS system was safe and had a high positioning accuracy and success rate.
