Role of perioperative parenteral nutrition in severely malnourished patients with Crohn＇s disease

AIM: To evaluate the effect of perioperative parenteral nutrition on serum immunoglobulin, weight change, and post-operative outcome in severely malnourished patients with Crohn's disease. METHODS: Thirty-two severely malnourished patients with Crohn's disease who had undergone surgery in our hospital were reviewed. Sixteen patients who received perioperative parenteral nutrition were enrolled in the study group, and the other 16 patients who did not receive parenteral nutrition were enrolled in the control group. Serum immunoglobulin, body mass index (BMI), liver function, weight change, and postoperative complications were evaluated. RESULTS: Serum IgM levels elevated 1 wk before surgery in both groups, and decreased to normal value (from 139±41 to 105±29 mg/dL, P= 0.04) 4 wk after operation in the study group, while no significant changes was noted in the control group (from 133±16 to 129±13 mg/dL, P=0.34). There were no significant changes in concentrations of IgG and IgA. The BMI of the study group increased from 13.9±0.6 to 15.3±0.7 kg/m~2 (P=0.02) with no significant change in the control group (14.1±0.7 and 14.5±0.5, respectively, P= 0.81). The percentage of resuming work was higher in the study group than in the control group. CONCLUSION: Perioperative parenteral nutrition possibly ameliorates the humoral immunity, reverses malnutrition, and facilitates rehabilitation.
