摘　　要：Background: Right upper lobectomy(RUL) for lung cancer with di erent dissecting orders involves the most vari?able anatomical structures, but no studies have analyzed its e ects on postoperative recovery. This study compared the conventional surgical approach, VAB(dissecting pulmonary vessels first, followed by the bronchus), and the alter?native surgical approach, a BVA(dissecting the posterior ascending arterial branch first, followed by the bronchus and vessels) on improving surgical feasibility and postoperative recovery for lung cancer patients.Methods: According to the surgical approach, consecutive lung cancer patients undergoing RUL were grouped into a BVA and VAB cohorts. Their clinical, pathologic, and perioperative characteristics were collected to compare periop?erative outcomes.Results: Three hundred one patients were selected(109 in the a BVA cohort and 192 in the VAB cohort). The mean operation time was shorter in the a BVA cohort than in the VAB cohort(164 vs. 221 min, P < 0.001), and less blood loss occurred in the a BVA cohort(92 vs. 141 m L, P < 0.001). The rate of conversion to thoracotomy was lower in the a BVA cohort than in the VAB cohort(0% vs. 11.5%, P < 0.001). The mean duration of postoperative chest drainage was shorter in the a BVA cohort than in the VAB cohort(3.6 vs. 4.5 days, P rvival was n= 0.001). The rates of postoperative complica?tions were comparable(P = 0.629). The median overall suot arrived in both cohorts(P > 0.05). The median disease?free survival was comparable for all patients in the two cohorts(not arrived vs. 41.97 months) and for patients with disease recurrences(13.25 vs. 9.44 months)(both P > 0.05). The recurrence models in two cohorts were also comparable for patients with local recurrences(6.4% vs. 7.8%), distant metastases(10.1% vs. 8.3%), and both(1.8% vs. 1.6%)(all P > 0.05).Conclusions: Dissecting the right upper bronchus before turning over the lobe repeatedly and dissecting veins via the a BVA approach during RUL would promote surgical feasibility and achiBackground: Right upper lobectomy(RUL) for lung cancer with di erent dissecting orders involves the most vari?able anatomical structures, but no studies have analyzed its e ects on postoperative recovery.
