Durations of preoperative measurement (minutes, median, range) 3, 2–10 3, 2–4
Durations of surgical procedure (minutes, median, range) 9, 5–32 7, 5–10
Pathologically negative surgical margin, n (%) 93 (100) 108 (100)
Sufficient surgical margin, n (%) 91 (98) 106 (98)
The distance from nodule to the marked visceral pleura (cm, median, range) 0.6, 0–1.5
Surgical procedures, n (%)
 Bilateral pulmonary operation 8 (9)
 Unilateral pulmonary operation for multiple lesions 13 (14)
 Multiple wedge resections 10 (11)
 Wedge resection and segmentectomy 8 (9)
 Wedge resection and lobectomy 7 (8)
