RESUMEN
Objective:To analyze the impact of colorectal cancer laparoscopic and open surgery on immune function.Methods:85 patients from January 2010 to December 2013 due to surgical treatment of colorectal cancer hospitalized in our department were randomly divided into experimental and control groups.The experimental group underwent laparoscopic surgery, the control group underwent laparotomy.The peripheral blood lymphocyte subsets, immunoglobulins, CRP and IL-6 levels, NO and ROS levels were compared in two groups of patients before and after one day,seven days of surgery.Results: The postoperative CD3,CD4,CD4/CD8 level after one day and seven days of surgery was significantly lower than before surgery, CD8 was significantly higher than before surgery,P0.05.Conclusion:Compared to open surgery,laparoscopic treatment of colorectal cancer has a protective and smaller effect for the body′s immune func-tion.
