Wedge resection. Radiofrequency identification (RFID) marker was placed 3 mm from the lesion. Within 5 seconds, the marker position was identified, and the position was marked with a 4-0 polydioxanone suture. To determine the depth of the deep margin, the lung was retracted upward, and the marker's location was carefully checked. After resecting the lung tissue by wedge resection, we examined the positional relationship between the lesion and the RFID marker.
