Objective To explore the application effect of laparoscopic resection of colorectal cancer in elderly patients.Methods 220 patients with colorectal cancer were selected and divided into the study group and the control group,ll0 cases in each group.The patients of the control group were treated with abdominal surgery.The patients of the study group were given laparoscopic surgery.The operative time,blood loss,anal exhaust time,postoperative hospital stay,and postoperative complications,pull tube time of the two groups were compared.Results The operative time of the study group was (245.4 ± 23.2) min,which was significantly longer than (214.8 ± 25.1) min of the control group(t =8.759,P =0.026) ; The blood loss,anal exhaust time,postoperative hospital stay,time to pull the tube of the study group were (175.3 ± 18.4)mL,(2.1 ±0.5)d,(13.2 ±0.1)d and (1.2 ±0.3) d,respectively,which were significantly better than those of the control group(t =9.041,9.757,8.969,8.704,P =0.025,0.023,0.027,0.028) ;The incidence rate of complication of the study group was 14.5％,which was significantly lower than 24.5％ of the control group(x2 =11.704,P =0.019).Conclusion Laparoscopic resection of colorectal cancer had better effect,and it can lower blood loss,shorter hospital stays,and has fewer complications.
