Abstract: Objective: To investigate the effects of different nutrition support methods on the postoperative recovery of elderly patients with colorectal cancer.Methods: Fity-six colorectal cancer patients with more than 65 years old were randomly divided into the control group and observation group(28 cases each group).The control group were treated with parenteral nutrition,and the observation group were treated with enteral nutrition combined with parenteral nutrition within 24 h after operation.The levels of blood urea nitrogen,serum total protein(TP),serum albumin (Alb) and plasma prealbumin before operation and postoperative 7 days between two groups were compared,and the postoperative anal exhaust time,postoperative complications,hospitalization time,and hospitalization cost between two groups were compared.Results: The postoperative TP and Alb levels in observation group were higher than those in control group(P<0.01),and the exhaust time,hospitalization time and hospitalization cost in observation group were less than those in control group(P<0.01).The difference of Pa and incidence of complication between two groups was not statistically significant(P>0.05).Conclusions: Early enteral nutrition can increase the levels of TP and Alb,quicken exhaust,shorten hospitalization time and reduce hospitalization cost of patients.
