Management of the Pulmonary Artery during Video-Assisted Thoracoscopic Left Upper Lobectomy

Complete video-assisted thoracoscopic surgery (c-VATS) for left upper lobectomy is difficult due to the branching pattern of the left pulmonary artery. Our purpose was to report outcomes of a modified technique of c-VATS left upper lobectomy. We retrospectively compared the outcomes of 83 patients with stage I/II non-small-cell lung cancer (NSCLC) who received left upper lobectomy between 2008 and 2011; 32 underwent conventional c-VATS and 50 received modified c-VATS. In the modified procedure, the order in which hilum of lung was treated was from the lingular segmental artery to the superior pulmonary vein to the bronchus, and then finally the pulmonary artery. The mean patient age was 63.6 +/- A 8.4 years, and no differences were observed in age, gender, and largest tumor diameter between the two groups. No conversion occurred in either group. The surgical time for modified c-VATS was significantly shorter than that for conventional c-VATS (210 vs. 270 min, p < 0.001). Drainage time after surgery and length of hospitalization for the modified c-VATS group were significantly less than those for the conventional group (drainage 3 vs. 4 days, respectively, p = 0.041; length of hospitalization 7 versus 12 days, respectively; p < 0.001). Surgical margins were clear in all cases. Four (8.0 %) complications occurred in the modified procedure group compared with ten (31.3 %) in the conventional group (p = 0.015). This new technique offers shorter surgical and postoperative drainage time, shorter hospital stays, and fewer complications than conventional c-VATS upper left lobectomy.
