abstract = {Background: Competency in video-assisted thoracoscopic surgery (VATS) lobectomy is estimated to be reached after 50 cases. Preoperative identification of individualized pulmonary vascular drainage is essential for the safe and fluent performance of single-direction uniportal VATS (UVATS) anatomic lobectomy. Digital anatomy models established by three-dimensional computed tomography bronchography and angiography (3D-CTBA) is therefore utilized to accumulate variations of the right upper lobe (RUL) veins, as right upper lobectomy is considered to be the most complicated and challenging procedure. This study aims to investigate the perioperative outcomes and learning curve of single-direction UVATS RUL lobectomy assisted with 3D-CTBA.
Methods: The patients who underwent single-direction intercostal UVATS anatomic RUL lobectomy after 3D-CTBA simulation by the same surgeon at Xuzhou Central Hospital between January 2017 and April 2019 were retrospectively reviewed (3D-CTBA group), and consisted of 99 males and 54 females, with a mean age of 61.6 years, with the variations of the RUL vein being assessed preoperatively. They were further divided into group A (30 cases), B (30 cases), C (30 cases), and D (63 cases), in accordance with the order of surgery. Meanwhile, the first 35 cases of single-direction UVATS RUL lobectomy by another experienced surgeon (after the learning curve of this procedure) who did not use 3D-CTBA was enrolled as a control group. The operation time, intraoperative blood loss, stations and numbers of harvested lymph nodes, the incidence of conversion to multiport VATS or thoracotomy, thoracic tube retention for drainage, complications defined under the Clavien-Dindo system, pain score, and postoperative hospital stay were analyzed. The previous surgical experience of the two surgeons was also evaluated.
Results: A significant difference was evident among the 5 groups in terms of age, smoking history, the proportion of neoadjuvant chemotherapy, and T staging of the tumors (P0.05, respectively).
Conclusions: Preoperative 3D-CTBA digital anatomy facilitates the safe and fluent performance of single-direction UVATS anatomic right upper lobectomy, with a learning curve of 30 cases. High-quality trials for better evidence are called for to verify these findings.},
