Clinical Study Of 50% Lower Lung Ligament Release In Thoracoscopic Pneumonectomy For Lung Cancer Patients Summary

OBJECTIVE: To compare the recent clinical effects of 50% lower lung ligament release and complete release during thoracoscopy superior lobectomy in lung cancer patients,and to explore the feasibility and clinical efficacy of50% lower lung ligament release during surgery.Methods: Patients with pathological diagnosis of lung cancer who underwent thoracoscopy for pulmonary lobectomy were taken as the research object.The study period was from January 2019 to November 2019.They were divided into two groups by the method of lottery and divided into experimental group(35 cases)and control group.Group(34 cases),the test group was to release50% of the lower lung ligament,and the control group was to release 100% of the lower lung ligament.The gender,age,smoking history,height,weight,preoperative pulmonary function,Cardiothoracic ratio and pathology.The two groups of patients were mainly compared with the time of 50% and 100%release of the lower lung ligament,the length of the lower lung ligament,the postoperative early lung retension,the postoperative complications,the length of hospital stay,and the cost of hospitalization.Results: There was no difference in age,gender,height,and weight between the two groups of patients.In the operation of the test group,the operation time of the release of the lower lung ligament was(6.76 ± 0.62)s on the left and(8.95± 0.57)s on the right;in the control group,the left was(112.56 ± 54.85)s.The right side is(126.86 ± 45.63)s.The time to release the lower lung ligament in the test group was significantly lower than that in the control group,which was statistically significant(P <0.05).In the experimental group,30 patients(85.7%)were discharged with full lung recovery 3 days after operation,4 patients(11.4%)were discharged with lung full recovery 5 days after operation,and 1patient was discharged with full lung recovery 7 days after operation(2.9%);21 patients(61.8%)were discharged with full lung recovery 3 days after operation,6 patients(17.6%)were discharged with full lung recovery 5 days after operation,and patients with residual lung completed 7 days after operation Seven patients(20.6%)were discharged after re-expansion.The rate of complete reexpansion of the remaining lung in the test group was significantly higher than that in the control group,which was statistically significant(P<0.05).The volume of thoracic drainage in the experimental group was low at 1day(119.89 ± 5.79)ml,2 days(197.14 ± 6.97)ml,and 3 days(143.97 ± 6.56)ml after surgery.There was statistical significance in the control group at 1 day(156.03 ± 4.18)ml,2 days after operation(265.88 ± 7.19)ml,and 3 days after operation(235.83 ± 7.12)ml.The retention time of closed drainage tube of the thoracic cavity in the experimental group(3.26 ± 1.12)days was significantly lower than that in the control group(5.15 ± 1.23)days(P <0.05).The postoperative complications of patients in the experimental group(2.86%)were lower than those in the control group(23.53%),which was statistically significant(P <0.05).The length of hospital stay in the experimental group was(4.09 ± 1.32)days,and the total cost during the hospital stay was(57644.46 ±328.95)yuan.The length of stay in the control group was(6.21 ± 1.28)days,and the total cost during the hospital stay was(70097.45 ± 216.45).yuan.The postoperative hospital stay and total cost of hospitalization in the experimental group were lower than those in the control group,which was statistically significant(P <0.05).Conclusion: Thoracoscopy lung cancer patients with 50% lower lung ligament compared with 100% lower lung ligament lung cancer patients can effectively reduce the difficulty of surgery,shorten the operation time,reduce intraoperative injuries,and reduce postoperative thoracotomy.Drainage tube drainage can promote the early re-extension of the affected side and compensate for lung function,reduce the incidence of postoperative related complications,promote rapid recovery of patients after surgery,shorten the length of hospital stay,and reduce the total cost of hospitalization.Thoracoscopy superior lung lobectomy for lung cancer patients using the 50%release of the lower lung ligament minimally invasive technology is safe and reliable,and the treatment effect is significant,which can be promoted and used in clinical practice.
