title: Energy and mineral utilization from a peptide-based elemental diet and a polymeric enteral diet given to ileostomists in the early postoperative course.
abstract: Small intestinal absorption was studied in 12 patients receiving enteral nutrition in the immediate postoperative period after colorectal surgery including construction of an ileostomy. Seven patients were given a peptide-based, low osmolality elementary diet and five patients were given a polymeric diet. Comparisons between the intake and ileal excretion showed on both diets a high utilization of energy, fat, and nitrogen as well as of calcium, phosphorus, magnesium, zinc, and iron. From a nutritional point of view a polymeric diet could thus replace an elementary diet in the immediate postoperative course.
