ABSTRACT
Objective:To investigate the effect of Nutrison MCT and Nutrison MF enteral nutrition on gut barrier function during the perioperative period in patient with malignant obstructive jaundice.Methods:82 cases of patients with malignant obstructive jaundice were randomized divided into Nutrison MCT group with 40 cases and Nutrison MF group with 42 cases.Enteral nutrition was given on admission.The level of urinary lactulose and mannitol(L/M) ratio,plasma endotoxin and diamine oxidase(DAO) activity on the 2nd day after admission,lday before surgery,5 days after full dose of enteral nutrition were collected.Results:Before surgery,no statistical significance difference of urinary L/M ratio,plasma endotoxin and DAO activity were found between the 2nd day after admission and 1day before surgery.After full dosing of enteral nutrition,urinary L/M ratio,plasma endotoxin and DAO activity were decreased,while Nutrison MCT group decreased more significantly than Nutrison MF group.Conclusion:Nutrison MCT can improve the gut barrier function of patients with malignant obstructive jaundice more earlier than Nutrison MF after surgery.
