Background: Total parenteral nutrition has a high cost and frequency of complications. Enteral feeding is a feasible alternative that can be started early in the postoperative period. Aim: To assess digestive tolerance to early enteral feeding in cancer patients undergoing total gastrectomy and to compare early enteral feeding (EEF) with total parenteral nutrition plus enteral feeding (TPN+EF), initiated after overcoming postoperative ileus. Patients and methods: Subjects with a resectable gastric cancer were considered eligible for the study. During surgery a nasoenteral tube was placed and patients were prospectively randomized to EEF or TPN+EF. Digestive tolerance, effectiveness, complications and costs between both modalities of nutritional support were compared. Results: Twenty eight patients (15 male, aged 63ñ14 years old) were studied. Fourteen patients were randomized to EEF and 14 to TPN+EF. Diarrhea occurred in 14 and 29 percent of EEF and TPN+EF patients respectively, (p: NS). Patients with TPN+EF received an average of 28 Cal/kg/day and 1.1 g/kg/day proteins. Patients with EEF received an average of 29 Cal/kg/day and 0.8 g/kg/day proteins. At the eighth postoperative day, serum albumin was 3.9ñ0.7 and 3.2ñ0.5 g/dl in EEF and TPN+EF patients respectively (p <0.05), serum prealbumin was 16.9ñ5 and 12.3ñ4.3 mg/dl in EEF and TPN+EF patients respectively (p <0.05) and nitrogen balance was +2.4ñ1.5 and -1.6ñ0.6 g/24 h in EEF and TPN+EF patients respectively (p <0.05). Postoperative hyperglycemia was observed with a lower frequency and nutritional support costs and length of hospital stay were significantly lower in the EEF group. Conclusions: After total gastrectomy EEF is well tolerated, safe and effective, even during the early postoperative ileus. This therapeutic modality could be the first choice for nutritional support in these patients
