[Nutrition therapy in enterocutaneous fistula; from physiology to individualized treatment].
Enterocutaneous fistula is the most common of all intestinal fistulas. Is a condition that requires prolonged hospital stay due to complications such as electrolyte imbalance, malnutrition, metabolic disorders and sepsis. Nutritional support is an essential part of the management; it favors intestinal and immune function, promotes wound healing and decreases catabolism. Despite the recognition of the importance of nutrition support, there is no strong evidence on its comprehensive management, which can be limiting when establishing specific strategies. The metabolic imbalance that a fistula causes is unknown. For low-output fistulas, energy needs should be based on resting energy expenditure, and provide 1.0 to 1.5 g/kg/d of protein, while in high-output fistulas energy requirement may increase up to 1.5 times, and provide 1.5 to 2.5 g/kg of protein. It is suggested to provide twice the requirement of vitamins and trace elements, and between 5 and 10 times that of Vitamin C and Zinc, especially for high-output fistulas. A complete nutritional assessment, including type and location of the fistula, are factors to consider when selecting nutrition support, whether is enteral or parenteral nutrition. The enteral route should be preferred whenever possible, and combined with parenteral nutrition when the requirements cannot be met. Nutritional treatment strategies in fistulas may include the use of immunomodulators and even stress management.
