Abstract:

Objective To investigate the safety and feasibility of complete mesocolon resection in elderly patients with colon cancer. Method 74 elderly patients with colon cancer treated in Xintai Second People's Hospital from March 2018 to March 2020 were divided into intervention group and control group by doubleblind method, with 37 cases in each group. The operation method of the intervention group was complete mesocolon excision, and the operation method of the control group was traditional colectomy. The incidence of complications, the recurrence rate of colon cancer, the number of lymph node clearance, the amount of

postoperative bleeding, the survival rate of 1 and 3 years after operation and the effective rate of operation were compared between the two groups. Result The incidence of postoperative complications and colon cancer recurrence in the intervention group were lower than those in the control group, There was significant difference (P ＜ 0.05); the number of lymphatic clearance in the intervention group was more than that in the control group, and the amount of postoperative bleeding was less than that in the control group, the difference was significant (P ＜ 0.05); the 1-year and 3-year survival rate and operation effective rate in the intervention group were higher than those in the control group, the difference was significant (P ＜ 0.05). Conclusion The effect of complete mesocolon excision in elderly patients is excellent, the amount of postoperative bleeding is less, and the postoperative survival rate of elderly patients is significantly improved, which has high safety and feasibility.
