A comparative analysis of the short-term efficacy of lung segmentectomy by Da Vinci robot and video-assisted thoracoscopy for stage ⅠA non-small cell lung cancer / 中华胸心血管外科杂志

ABSTRACT

Objective:To compare the short-term outcomes of segmentectomy for stage ⅠA non-small cell lung cancer by two surgical methods.Methods:A retrospective analysis was performed on 101 patients with stage ⅠA non-small cell lung cancer and undergoing segmentectomy admitted to the Department of Thoracic Surgery of The General Hospital of the Northern Theater Command from July 2016 to July 2020, including 50 patients who underwent Da Vinci robotic segmentectomy and 51 patients who underwent video-assisted thoracoscopic segmentectomy during the same period. By collecting the clinical data of the patients, the operation time, intraoperative blood loss, lymph node dissection stations, lymph node dissection number, drainage volume on the first day after the operation, total drainage volume on the third day after the operation, postoperative chest catheter insertion time, postoperative hospitalization days, and postoperative complication rate were compared and analyzed.Results:Patients in both groups successfully completed pulmonary segmental resection, and there were no cases of conversion to thoracotomy and perioperative death.Compared and analyzed the postoperative clinical results of the two groups, the intraoperative blood loss [(34.40±12.96) ml vs.(85.10±26.41)ml, P=0.000], the number of lymph node dissection stations(4.72±1.20 vs. 3.60±1.40, P=0.000) and the number of lymph node dissection(15.14±5.91 vs. 10.76±5.26, P=0.000) showed statistically significant differences, and RATS group was superior to VATS group.There were no statistically significant differences in operation time[(153.90±21.88) min vs.(155.39±25.04) min, P=0.751], drainage volume on the first day after surgery[(217.80±76.94) ml vs.(210.98±86.98) ml, P=0.678], total drainage volume three days after surgery[(612.60±169.93) ml vs.(595.10±203.90) ml, P=0.641], duration of chest drainage tube after operation[(5.36±2.33) days vs.(5.18±2.54) days, P=0.706], postoperative hospitalization days[(7.50±2.35) days vs.(7.47±2.93) days, P=0.956]and postoperative complication incidence. Conclusion:Da Vinci robot segmentectomy is a safe and effective surgical method, with less bleeding and more lymph node dissection stations and number than video-assisted thoracoscopic segmentectomy for stage ⅠA non-small cell lung cancer.
