Purpose : Benefits of inferior pulmonary ligament (IPL) division during video-assisted thoracoscopic surgery (VATS) upper lobectomy for early-stage lung cancer remains controversial. Here, we evaluated the effect of IPL division during VATS left upper lobectomy by comparing the lung volume, bronchial angle, and bronchial tortuosity of the left lower lobe.

Methods : We retrospectively evaluated the medical records and images of patients who underwent VATS left-upper lobectomy between January 2014 and January 2017. Patients were divided into the preservation group (group P) and division group (group D). Pre- and post-operative lung volume, bronchial angle (angle 1, axial angulation; angle 2, vertical angulation), and bronchial tortuosity (using curvature index) were compared via CT images

Results : Forty patients were included in each group. Preoperative lung volume, preoperative bronchial angles, and preoperative bronchial tortuosity were not significantly different between the two groups. There was no significant difference with respect to pre- and postoperative angle 1 change (2.95 ± 0.88° vs. 5.74 ± 1.21°; p = 0.065) and angle 2 change (15.73 ± 1.33° vs. 19.21 ± 1.73°; p = 0.11). However, there was significant difference in pre- and post-operative lung volume change (p = 0.03); groups P and D showed decrease of 27.75 ± 1.48% and 32.97 ± 1.93%, respectively. The significant difference between pre- and post-operative left main bronchus CIs was 0.02 ± 0.02 and 0.06 ± 0.04 in groups P and D (p = 0.01).

Conclusion : Preservation of IPLs during left-upper lobectomy may yield better outcome with respect to volume and bronchial tortuosity.
