Analysis of the effect of different chest drainage after uniportal video-assisted thoracoscopic radical operation for lung cancer

Objective To investigate the effect of different thoracicdrainage methods afte single holethoracoscopicsurgery for lung cancer. Methods 200 patents with lung cancer undergoing single holethoracoscopicsurgery were divided into two groups : group A and group B in the first affliliated Hospital of Suzhou University from April 2014 to December 2016. Group A: 100 patients with 30#single thoracic drainage tube after operation. Groupe B: 100 patients with 30#thoracic drainage tube plus a negative pressure drainage tube after operation. The amount of thoracic drainage tube , drainage time , postoperative chest puncture, postoperative pain, hospital stay and total costs of hospitalization were observed in both groups. Results There was no difference in age, sex, pathological type and pulmonary lobectomy between the two groups. Total thoracic drainage[(1 007.4±512.95)ml vs.(982.35±359.93)ml]and totaltube time[(5.71±2.61)days vs.(5.43±1.91) days] had no significant difference between the two groups. There was a significant difference in the length of 30#thoracic drainage tube [(5.71±2.61)days vs.(2.9±0.61)days]between the two groups. The difference of hospitalization time[(12.05±2.93)days vs.(13.45±4.15)days]and hospitalization expenses[(63 376.47±1 615.82)yuan vs.(64 449.82±3 650.04)yuan]was statistically significant. The rate of rethoracotomy in gruop A was 7%, the rate of rethoracotomy in group B was 0, the comparison between the two groups was statistically significant. VAS pain scores were compared on the first day and the second day, there was no significant difference on the third day after operation. On the fifth day after operation, the difference was statistically significant. Conclusion Adding a negative pressure drainage tube on the basis of using a single thoracoscopic drainage tube for radical resection of lung cancer after single hole thoracoscopic surgery will not increase postoperative pain of patients, significantly shorten postoperative hospitalization time, effectively control postoperativerethoracopunchure rate, thus effectively reduce postoperative hospitalization costs of patients. Key words: Single hole Thoracoscopic Radical resection of lung cancer Thoracic drainage
