Comparative analysis of the effect of lymph node dissection by VATS lung resection surgery and conventional lung cancer surgery

Abstract

Objective To compare the effect of lymph node dissection by VATS lung cancer resection surgery and conventional lung cancer surgery. Methods 120 patients with non-small cell lung cancer were selected and randomly divided into observation group(n=60) and control group(n=60)according to the digital table.The control group was given conventional resection of lung cancer treatment, the observation group was assisted thoracoscopic lung resection treatment.The postoperative drainage, postoperative ambulation time, postoperative hospital stay, the number of lymph node metastasis and incidence rate of postoperative complications were observed. Results The time of postoperative drainage, get out of bed and postoperative hospital stay of the observation group were all shorter than those of the control group[(2.43±0.54)d vs.(5.82±1.35)d, (1.23±0.29)d vs.(3.87±0.75)d, (2.59±0.63)d vs.(6.92±1.27)d; t=18.059, 25.430, 23.658, all P 0.05). The positive rate of lymph node metastasis in the observation group was lower than that in the control group(χ2=7.033, P<0.05). The incidence rate of postoperative complication of the observation group was lower than that of the control group(χ2=6.708, P<0.05). Conclusion Video-assisted thoracoscopic lung resection for non-small cell lung cancer patients with lymph node dissection is better than conventional lung surgery, and it is worthy of studying.
