RESUMEN
OBJECTIVE: Anastomotic leakage is one of the most important causes of morbidity and mortality in gastrointestinal surgery. We investigated the effect of oral glutamine on the healing of high-output intestinal fistula. SETTING: A tertiary Universitary Hospital of the University of Mato Grosso, Cuiaba, Brazil. PATIENTS AND METHODS: 28 patients (25 males and 3 females; median age = 45 [18-71] years old) admitted with high output post-operative small bowel fistulas (median volume in 24 h: 850 [600-2,200] mL) during a 4 years period were retrospectively studied. INTERVENTIONS: In the first two years 19 (67.9%) patients received only TPN as the initial nutritional support. In the last two years however, due to a change in the protocol for the nutritional support in cases of intestinal fistula 9 patients (32.1%) received oral glutamine (0.3 g/kg/day; 150 mL/day) in addition to TPN. Endpoints of the study were mortality, resolution of the fistula, and length of hospital stay (LOS). RESULTS: The overall mortality was 46.4% (13 patients). Fistula closure was observed in all other 15 patients (53.6%) that survived. In the subset of survived patients LOS was similar in those who received or not received glutamine. The multivariate regression analysis showed that resolution of the fistula was 13 times greater in patients that received oral glutamine (OR = 13.2 (95% CI = 1.1-160.5); p = 0.04) and 15 times greater in non-malnourished patients (OR = 15.4 [95% CI = 1.1-215.5]; p = 0.04). CONCLUSIONS: We conclude that oral glutamine accelerated the healing and diminished the mortality in this series of patients with post-operative high-output intestinal fistula receiving TPN.

AIM: The aim of this study was to investigate factors that may affect the evolution of the caloric prescription in critically ill patients. Local: Intensive care unit patients. PATIENTS: 60 patients (33 M and 27 F); median age = 49 (1593) y were followed prospectively. They were divided in three groups according to the diagnostic: (a) trauma (n=20); (b) surgical (n=22), and 3) medical treatment (n=18). Forty-and-one (68.3%) patients received enteral nutrition (EN), 17 (28.3%) parenteral nutrition (TPN), and 2 (3.4%) TNP and EN. Nutritional status was graded B or C by global subjective evaluation. METHODS: Endpoints of the study were the time to begin the nutritional support, success or failure of the caloric prescription, and the evolution of the planned caloric prescription. The caloric evolution was considered as success if the prescription for the patient attained: (a) 25% of the caloric requirements on the 1st day; (b) 50% until the 3rd day; (c) 75% until the 6th day; and (e) 100% until the 10th day of the beginning of the support. RESULTS: In 54 (90%) patients, the nutritional support has begun until 48 h after admission and in 73.3% (44 patients), until the first 24 hours. EN was most prescribed for both trauma and medical patients while NPT was most used for surgical patients (p < 0.01). Success in caloric prescription was obtained in 73.3% (44) of the patients. There was no statistical difference for the success on the evolution of the prescription related to sex, age, diagnostic group, albumin level, type of support, mortality, use of fiber or glutamine. Success was attained earlier in patients without (median = 3.8 [95% CI, 5.7-16.7] days) than with (11.2 [95% CI, 5.7-16.7] days; p < 0.01) mechanical ventilation. CONCLUSIONS: Early nutritional support and success on the evolution of the caloric prescription can be accomplished in most critically ill patients. Evolution of the caloric prescription was slower in mechanical ventilated patients.
