[Effects of preoperative artificial nutrition in intestinal resections for Crohn disease]. / Effets de la nutrition artificielle préopératoire dans les résections intestinales pour maladie de Crohn.

UNLABELLED: Artificial nutrition prior to bowel resection has not been evaluated fully. The aim of the present study was to assess the effects of preoperative artificial nutrition upon postoperative complications, length of resected bowel and relapses of Crohn disease. RESULTS: Between 1990 and 1994, 108 consecutive patients underwent bowel resection for Crohn disease. Thirty nine patients had received exclusive enteral nutrition (n = 14) or parenteral nutrition (n = 25) for 19 +/- 10 days. Patients who had received artificial nutrition were more malnourished and had complicated Crohn disease (fistulae, abscesses) more often than patients operated without artificial nutrition. After 19 days of artificial nutrition, the nutritional state of patients was not significantly improved. Postoperative complication rate was higher in patients operated after artificial nutrition (33 vs. 16%; P = 0.03). Using multivariate prognosis analysis, the extent of colic resection was significantly associated with postoperative complications (P = 0.0003). Length of resected bowel and relapse rates were similar in patients with or without preoperative nutrition. CONCLUSION: Artificial nutrition prior to bowel resection for Crohn's disease is indicated in patients with the most severe form of the disease. A preoperative nutrition of 19 days does not seem to reduce postoperative complications nor the length of resected bowel.
