Abstract:Objective To investigate the effect of iso-incremental enteral nutrition infusion on the nutritional status and early enteral nutrition (EEN) feeding tolerance of hilar cholangiocarcinoma patients.Methods A total of 80 postoperative patients with hilar cholangiocarcinoma treated in our hospital between February 2018 and March 2020 were selected, and were randomly divided into two groups. 40 cases in the reference group got enteral nutrition support with intermittent infusion method, and 40 cases in the observation group got enteral nutrition support with the iso-incremental infusion method. The intervention time of nutritional support for both groups was averagely 10 d. The levels of nutritional status indicators such as prealbumin, transferrin, albumin of patients in both groups were detected 1 d before and 10 d after surgery. The EEN feeding tolerance questionnaire of patients in both groups was evaluated. The complications of both groups were observed after operation.Results There were no differences in the levels of prealbumin, transferrin, and albumin between the reference group and the observation group 1 d before surgery (P>0.05). However, 10 d after surgery, the levels of prealbumin, transferrin, and albumin were significantly higher in the observation group than in the reference group (P<0.05). The total tolerance rate of EEN in the observation group was higher than in the reference group (P<0.05). There were no differences in immune status indexes of CD4+, CD8+, and CD4+/CD8+ between the two groups at 1 d before surgery (P>0.05). However, 10 d after surgery, the level of CD8+ in the observation group was significantly lower than in the reference group, while the CD4+/CD8+ was significantly higher than in the reference group (P<0.05). The incidence of intraperitoneal infection in the observation group was significantly lower than in the reference group (P<0.05).Conclusion Iso-incremental enteral nutrition infusion is worthy of clinical application in patients with hilar cholangiocarcinoma, for it can improve the nutritional status, increase the EEN feeding tolerance, enhance the immune function, and reduce the risk of abdominal infection of patients.
