Introduction: Among the different factors described, nutritional support has been associated to prevention and management of enterocutaneous fistulae (ECF). Objectives: To assess the influence that the parameters related to nutritional, clinical status, and surgical variables have on the occurrence of ECF. Methods: An observational case/control retrospective study was performed on patients admitted to the General and Digestive Surgery Department. The parameters analyzed were: diagnosis, body mass index (BMI), pathologic personal history, number of surgical interventions (SI) and complications (previous infection, bleeding, and ischemia). In patients with SI, we analyzed: number and type of SI, time until onset of nutritional support, and type of nutritional support. We performed a multiple logistic uni- and multivariate regression analysis by using the SPSSv.19.0 software. Results: The primary diagnoses related to the occurrence of ECF were pancreatic pathology (OR = 5.346) and inflammatory bowel disease (IBD) (OR = 9.329). The surgical variables associated to higher prevalence of ECF emergency SI (OR = 5.79) and multiple SI (OR = 4.52). Regarding the nutritional variables, the late onset of nutrition (more than three days after SI) was associated to the occurrence of ECF (OR = 3.82). Conclusions: In surgical patients, early nutritional support , independently of the route of administration, decreases the occurrence of fistulae. Pancreatic pathology, IBD, emergency SI, and multiple SI were associated to higher prevalence of ECF. The variable hyponutrition appears as a risk factor that should be confirmed in further studies.

Introduction: In parenteral nutrition it is necessary to adjust the intake to the estimated caloric requirements. These needs may be achieved by the use of bi- or tricameral nutrition (EPN), although they present some rigidity regarding their composition. Objective: To assess the adequacy of caloric intake using EPN, to determine the factors conditioning it and the associated complications. Methods: Cohort, prospective, and observational study for 9 months in surgical patients. The calculated needs were compared with actual intake. The factors conditioning the excess and deficit (weight, age, stress factor, height, glycemia, and triglyceridemia) were studied by means of a multivariant method. The metabolic complications associated to the excess or deficit (hyperglycemias, hypertriglyceridemias) were studied by using the Student's t test. The theoretical calculations with the Harris-Benedict and the Mifflin equations were compared by lineal correlation regression. Results: 94 patients were studied. In 87% of them, the caloric intake was within the +/- 15% range of the theoretical mean. Thirty patients had caloric excess, whereas 61 had deficit. Patients with high weight (> 68 kg), stress factor > 1.2, and hypertriglyceridemias (> 3 mmol/L) had higher risk for caloric deficit. Twenty two point eight percent had hyperglycemias that were correlated with caloric excess. Nineteen point eight percent had hypertriglyceridemias associated to caloric deficit. When comparing both formulas, the values correlated well except for those patients with low weight and advanced age. Discussion: Although EPN fits the caloric requirements in most of the patients, in those with high weight, hypercatabolism, and hypertriglyceridemia there is a risk for caloric deficit.
