Prolonged enteral nutrition in malnourished patients with nonelemental feeding. Reappraisal of surgical technique, safety, and costs.

In a 2 year period, 60 consecutive feeding enterostomies were placed in malnourished patients. The major complication rate was 1.6 percent. Total complications were 8 percent. Thirty day mortality was 13 percent. Nearly all patients were given isosmotic nonelemental diets. The incidence of diarrhea was 2 percent with this regimen. Four of five patients given elemental diets had diarrhea. Serum albumin levels increased significantly from a preoperative mean of 2.75 to 3.03 g/dl. Best overall results were achieved in patients undergoing upper gastrointestinal surgery or pancreatobilary procedures for nonmalignant lesions. More than $60,000 was saved in 2 years by substituting isosmotic formulas for elemental ones. It appears that many patients are given elemental formulas who do not actually require them. Since isosmotic solutions will not infuse through needle catheters, we advocate placing 12 F. catheters and have documented the safety of this change. By using these larger catheters, the surgeon will not lose the option of using isosmotic preparations. We have shown these preparations to be nutritionally effective with a marked lessening of diarrhea and a cost approximately a sixth of that of elemental products.
