Abstract: 【Abstract】 Objective To study the effect of ω-3 fish oil on nutrition and immune function in postoperative patients with gastrointestinal malignant tumors. Methods Sixty cases of gastrointestinal malignant tumor from May 2010 to May 2013 were studied. All patients were randomly divided into experimental group and control group, with 30 cases of patients in each group. All patients were got parenteral nutrition support with equal nitrogen and calorie postoperatively, but the experimental group added ω-3 fish oil on the basis of routine treatment. All patients’ liver function, blood lipids, Hb, ALB, TF, lymphocyte count (TLC), B lymphocyte subsets (B1, B2), immunoglobulins (IgG, IgM, IgA) and complement(C3,C4) level preoperatively were measured in postoperative day 1 and postoperative day 6 respectively. Results There were no significant differences between experimental group and control group in liver function, blood lipid, but in postoperative day 6, the significant differences were found in the levels of TLC, IgG, IgM, C3 between the two groups(P<0.05). Conclusion Omega-3 fish oil has no significant effect on the postoperative nutrition for gastrointestinal cancer patients, while it would improve the immunity of the patients.
