The Clinical Analysis Of Video-assisted Thoracoscopic Surgery And Traditionl Surgical Treatmenton The Non-small Cell Lung Cancer In Systematic Node Dissection

Objective By comparing the VATS and traditional surgery non-small cell lung cancer the clinical data of lymph nodedissection.Investigate systematic lymph node dissection feasibility of the treatment technique of thoracoscopic in non-small cell lung cancer.Methods We performed a retrospective review of618patients who underwent the VATS lobectomy and open thoracotomy from September2011to January2014. Who was diagnosed with preoperative staging of lymph node negative (cNO) non-smallcell lung cancer.Of the611patients VATS was207patients conventional thoracotomy was411patients. The comparative analysis of two groups of patients of preoperative clinical data, the number ofmediastinal lymph node dissection group, the total number of positive lymphnodes, the positive nodes proportion and the CN0-PN2proportion.Results The clinical material of618cases patients were reviewed,207patients were taken by VATS,411patients were taken by conventional thoracotomy. The patients who were diagnosed with preoperative staging of lymph node negative (cNO) non-smallcell lung cancer were180,of which VATS was62patients, conventional thoracotomy was118patients. The patients who were diagnosed with mediastinal lymph node-positive were107, of which VATS was38patients, conventional thoracotomy was69patients.The two groups were similar in age. gender distribution, Tumor location, clinical stage and the type of cases.The cNO-PN2patients accounted for the cNO ratio in the three surgical methods were18.36%、16.79%P=0.352.The statistical analysis no significant difference.The lymphadenectomy number of VATS and traditional surgery were30.10±12.18、32.36±13.08P=0.211.The mediastinal lymph node-positive number were18.02+10.07、19.01+9.20P=0.297. The mean N1lymph node number were9.76±5.43、11.45±6.18P=0.071.The positive lymph node number:1.49±3.69.1.87±4.12P=0.299.Lymph node metastasis rates were4.81%、4.79%P=0.490.The mean post operative drainage volume and the postoperative drainage time was similar.Conclusion Thoracoscopic operation for treatment of non small cell lung cancer with traditional operation as complete mediastinal lymph node dissection.
