Objective To observe the clinical curative effect of nonsmall cell lung cancer treated by videoassisted thoracoscopic lobectomy. Methods 82 cases diagnosed with nonsmall cell lung cancer were randomly divided into the control group and the control group,41 cases each group. Traditional lobectomy was performed in the observation group,while videoassisted thoracoscopic lobectomy was performed tin the observation group. Intraoperative and postoperative situations,2year rates of metastasis,recurrence and survival were compared. Results The intraoperative blood loss,the total flow and drainage tube indwelling, length of hospital stay,postoperative analgesia drug use frequency of the observation group were shorter or less than those of the control group (P <0. 05). There was no difference in terms of the number of dissected lymph nodes and the operation time. There were complications in 4 cases in the observation group(9. 76% ),and 13 cases in the control group(31. 70% )(P < 0. 05). In the observation group,4 cases were lost followup, 2 cases had distant metastasis (4. 88% ),5 cases had mediastinal lymph node metastases (12. 19% ),and 2year diseasefree survival rate was 87. 80% (35 /41),3 cases died during the followup period,and 2year survival rate was 87. 80% (36 /41). Of the control group,3 were lost to followup,with the followup rate of 92. 68% ,6 cases had distant metastasis (14. 63% ),5 cases had mediastinal lymph node metastases(12. 19% ),2year diseasefree survival rate was 73. 17% (30 /41),8 patients died of advanced cancer during the followup period,2year survival rate was 80. 78% (33 /41). The 2year diseasefree survival rate showed no significant difference,and the 2year survival rate showed significant difference (χ2 = 4. 22, P <0. 05). Conclusion VATS lobectomy treating for Ⅰ,Ⅱ stage nonsmall cell lung cancer results in fewer postoperative complications than thoracotomy,showing security of oncology therapy.
