    Abstract:
    BACKGROUND: Most cholangiocarcinoma patients with malignant obstructive jaundice (MOJ) have varying degrees of malnutrition and immunodeficiency preoperatively. Therefore, perioperative nutritional support has important clinical significance in the treatment of cholangiocarcinoma. AIM: To investigate the effects of postoperative early enteral nutrition (EEN) on immunity function and clinical outcomes of cholangiocarcinoma patients with MOJ. METHODS: This prospective clinical study included 60 cholangiocarcinoma patients with MOJ who underwent surgery. The patients were randomly divided into an experimental group and a control group according to the nutrition support modes. The control group received postoperative total parenteral nutrition (TPN), whereas the experimental group received postoperative EEN and parenteral nutrition (PN; EEN + PN). The clinical outcomes, postoperative immune function, incidences of surgical site infection and bile leakage, intestinal function recovery time, average hospitalization days, and hospitalization expenses of the two groups were assessed on postoperative days (PODs) 1, 3, and 7. RESULTS: The CD3+T, CD4+T, CD8+T, and CD4+T/CD8+T cell count and the immunoglobulin (Ig) G, IgM, and IgA levels in the EEN + PN group were significantly higher than those in the TPN group on PODs 3 and 7 (P < 0.05), whereas no significant differences in the CD3+T, CD4+T, CD8+T, and CD4+T/CD8+T cell counts and IgG, IgM, and IgA levels before operation and on POD 1 were found between the two groups (P > 0.05). The intestinal function recovery time and postoperative hospital stay were shorter (P < 0.001 for both) in the EEN + PN group than in the TPN group. The hospitalization expenses of the EEN + PN group were lower than those of the TPN group (P < 0.001). However, the incidence of abdominal distension was higher than in the EEN + PN group than in the TPN group (P < 0.05). The incidence rates of biliary leakage and surgical site infection were not significantly different between the two groups (P > 0.05). CONCLUSION: A postoperative EEN program could reduce the incidence of postoperative complications and improve the clinical outcomes and immune functions of cholangiocarcinoma patients with MOJ and is thus beneficial to patient recovery.
