Objective To make contrast analysis of sleeve lobectomy and wedge resection in lung cancer treatment by observing the clinical curative effect.Methods 100 patients with lung cancer using random table method, all the patients were divided into the observation group ( 50 cases, treated with sleeve resection ) , control group (50 cases,treated with wedge resection),follow-up after treatment lasted respectively for 3 years.Results In the two groups,anastomotic fistula incidence and mortality rates of the observation group were 4%,6%;6% and 8% in the control group,there were no statistical difference (χ2 =0.00,0.00,all P>0.05);the positive rate of stump cancer cell bronchial in the observation group was 4%,it was obviously less than 16% in the control group,and the differ-ence was obvious (χ2 =4.00,P<0.05) .The anastomotic scar tissue hyperplasia and recurrence rate of the observa-tion group during the follow-up period were 2%,2%;which were lower than 16%,18% of the control group (χ2 =4.40,7.11,all P<0.05).The 1,3 year survival rates of the observation group were 92%,64%,which were higher than 62%and 42%of the control group (χ2 =12.70,4.86,all P<0.05).Conclusion Taking sleeve resection for bronchogenic carcinoma can effectively control the positive rate of bronchial stump with cancer cells,inhibit anasto-motic scar tissue hyperplasia,reduce the recurrence rate,and the curative effect is very good,which is worth of clinical application.
