ABSTRACT
BACKGROUND:
The radiofrequency identification (RFID) lung marking system is a novel technique using near-field radio-communication technology. The purpose of this study was to investigate the utility and feasibility of this system in the resection of small pulmonary nodules.METHODS:
We retrospectively reviewed clinical records of 182 patients who underwent sublobar resection with the RFID marking system between March 2020 and November 2021 in six tertial hospitals in Japan. Target markings were bronchoscopically made within 3 days before surgery. The contribution of the procedure to the surgery and safety was evaluated.RESULTS:
Target nodule average diameter and depth from the lung surface were 10.9 ± 5.4 mm and 14.6 ± 9.9 mm, respectively. Radiologically, one third of nodules appeared as pure ground-glass nodules (GGNs) on CT. The average distance from target nodule to RFID tag was 8.9 ± 7.1 mm. All surgical procedures were completed by video-assisted thoracoscopic surgery. Planned resection was achieved in all cases without any complications. The surgeons evaluated this system as helpful in 93% (necessary 67%, useful; 26%) of cases. Nodule radiological features (p < 0.001) and type of surgery (p = 0.0013) were associated with the degree of contribution. In most cases, identification of the RFID tag was required within 1 min despite adhesion (p = 0.27).CONCLUSION:
The RFID lung marking system was found to be safe and effective during successful sublobar resection. Patients with pure GGNs are the best candidates for the system.Palavras-chave
