Pulmonary Function After Segmentectomy

By JCOG0802/WJOG4607L published in 2022, a superiority of pulmonary function in segmentectomy group was shown over that in lobectomy group with significance (p < 0.0001) [1]. But postoperative forced expiratory volume in 1 s (FEV1) in segmentectomy group was just 3.5% higher than that in lobectomy group. A shortage of the study is that it does not show the extent of segmentectomy.
