Effects of early enteral nutrition containing dietary fiber on nutritional status and immune function of patients following surgery for carcinoma of stomach / 肠外与肠内营养

ABSTRACT

Objective: To evaluate the effects of enteral nutrition(EN) containing dietary fiber and parenteral nutrition(PN) on nutritional status and immune function of patients following surgery for carcinoma of stomach.Methods: 60 patients who underwent surgery for carcinoma of stomach were randomized to PN group(n=20),Pepti-2000(elemental diet) group(n=20) or Nutrison Multi Fibre(EN containing dietary fiber) group(n=20) for 7 days.Isocaloric and isonitrogenous nutritional supports began at the first day after operation and were maintained for a week.Nutritional variables such as body weight,serum albumin,transferin and accumulated nitrogen balance were measured preoperatively and on the 8th day after operation.Meanwhile,immune variables such as peripheral lymphocytes counts,subsets of lymphocytes(CD3,CD4,CD8,CD25),NK cells,serum immunoglobulins(IgG,IgM,IgA),complement system(C3,C4,CH50) and C-reactive protein(CRP) were also determined.Results: No serious complications occurred in all groups after surgery.Body weight decreased significantly in all groups(P
