Abstract:Objective To study the impact of laparoscopic radical resection and open radical resection on immune function in patients with colon cancer. Methods 110 cases received complete mesocolic excision surgery of the right colon cancer patients, according to the different surgical methods divided into observation group and control group, the observation group adopted laparoscopic surgery while the control group treated with open surgery, then compared the inflammatory stress response and related immunology index changes before and after operation. Results After operation, inflammatory stress indicators such as MCP-1, HMGB-1, Glucagon, BG in observation group were significantly better than that in control group. After operation, WBC, CRP, IL-6 index in the two groups were significantly improved. CRP, IL-6, CD4+, CD8+, NK cell index in observation group was significantly better than that in control group. There were significant differences between the two groups, P < 0.05. Conclusion Laparoscopic CME surgery can help to relieve inflammatory stress response, and the immune function is less affected, it is worthy of promoting clinical application.
