ABSTRACT
Objective@#To study the clinical effect of video-assisted thoracoscopic surgery in the treatment of early non-small cell lung cancer(NSCLC).@*Methods@#130 cases with early NSCLC were selected.According to random number table, the patients were divided into the observation group and the control group, 65 cases in each group.The observation group was treated with video-assisted thoracoscopic surgery, while the control group was treated with thoracotomy.The perioperative period of the two groups was compared, 24h before operation and 24h after operation, the changes of T lymphocyte subsets(CD3+ , CD4+ , CD4+ /CD8+ ) were measured, and the postoperative complications were recorded.The patients were followed up for one year, the survival rate and recurrence rate were recorded.@*Results@#There was no statistically significant difference in the number of lymph node dissection between the two groups(t=1.023, P>0.05). The operation time of the observation group was significantly longer than that of the control group(t=6.479, P<0.05), the amount of bleeding of the observation group was significantly less than that of the control group, the postoperative drainage time and ambulation time of the observation group were significantly shorter than those of the control group, the pain score of the observation group was lower than that of the control group, the differences were statistically significant(t=17.081, 16.040, 39.443, 21.237, all P<0.05). After operation, the CD3+ , CD4+ , CD4+ /CD8+ in the two groups were significantly reduced compared with before operation(observation group: t=5.591, 5.300, 4.300; the control group: t=10.450, 10.735, 4.883, all P<0.05), the CD3+ , CD4+ , CD4+ /CD8+ of the observation group were significantly higher than those of the control group[(58.95±7.58)% vs.(52.42±7.52)%, (34.83±3.75)% vs.(30.07±3.12)%, (1.21±0.17) vs.(1.15±0.13), t=4.931, 7.867, 2.260, all P<0.05]. The incidence rate of complications of the observation group was significantly lower than that of the control group[6.15%(4/65) vs.18.46%(12/65), χ2=4.561, P<0.05]. The patients were followed up for 1 year, there were no statistically significant differences in survival and recurrence between the two groups(χ2=0.367, 0.208, all P>0.05).@*Conclusion@#Video-assisted thoracoscopic surgery is well for early NSCLC patients, with advantages of small trauma, quick recovery, and it can help to protect the immune function of the organism, the clinical value is high.
ABSTRACT
Objective To compare the effect of lymph node dissection by VATS lung cancer resection surgery and conventional lung cancer surgery.Metnods 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 lymph node dissection number of the two groups had no statistically significant difference(x2 =1.008,P ＞ 0.05).The positive rate of lymph node metastasis in the observation group was lower than that in the control group(x2 =7.033,P ＜ 0.05).The incidence rate of postoperative complication of the observation group was lower than that of the control group (x2 =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.
