[Enteral Nutritional Support in Gastrointestinal and Liver Diseases]

Nutritional support is important because malnutrition is a major contributor to increased morbidity and mortality, decreased quality of life, increased length of hospital stay, and higher healthcare costs. Patients with gastrointestinal disease are at an increased risk of nutritional deterioration due to therapeutic dietary restriction, fasting for the diagnostic tests, loss of appetite due to anorexia or altered nutritional requirement caused by the disease itself. Therefore, it is important that gastroenterologists are aware of the nutritional status of patients and plan a treatment strategy considering patient's nutritional status. Enteral nutrition is preferred to parenteral nutrition as it is more physiologic, has fewer complications, help to prevent mucosal atrophy and maintain gut barrier function, which decrease intestinal bacterial translocation. Hence, enteral nutrition has been considered to be the most effective route for nutritional support. In this article, we will review enteral nutrition (oral nutritional supplements, enteral tube feeding) as a treatment for the patients with gastrointestinal, liver and pancreatic disease at risk of malnutrition.
