Objective:To explore the effects of early enteral nutrition combined with triple viable capsule of bacillus on inflammatory factors and intestinal mucosal barrier function in treatment of severe acute pancreatitis.Methods:118 cases of severe acute pancreatitis were randomly divided into two groups. The control group (59 cases) patients were treated with early enteral nutrition therapy, while the observation group (59 cases) was treated with early enteral nutrition combined with triple viable capsule of bacillus. The clinical efficacy of the two groups and the changes of the levels of inflammatory factors and the function of intestinal mucosal barrier were compared.Results:The time of abdominal pain disappearance, the abdominal distension disappeared, and the recovery time of the exhaust function of the observation group were (2.30±0.30) d, (3.39±0.51) d and (2.68±0.78) d, were significantly decreased compared with the control group (P<0.05). IL-6, IL-8, TNF-α and CRP of observation group were (33.19±355) g/L, (30.28±3.71) g/L, (36.33±3.53) g/L and (12.19±1.18) mg/L, were significantly lower compared with those before treatment (P<0.05) and was significantly lower than that of the control group (P<0.05). After treatment, D-lactate, DAO, endotoxin and exami of observation group were (544±0.54) mg/L, Dao (4.11±0.34) U/L, (0.65±0.18) EU/L, (0.15±0.07), were decreased significantly compared with those before treatment (P<0.05) and was significantly lower than that of the control group (P<0.05).Conclusion:Eearly enteral nutrition combined with triple viable capsule of bacillus on inflammatory factors and intestinal mucosal barrier function in treatment of SAP has significant effect, can rapidly improve the symptoms of patients, reduce inflammation, promote the recovery of intestinal mucosal barrier function, it is worth clinical reference and popularization and application.
