title: Enteral nutrition and mucosal immunity: implications for feeding strategies in surgery and trauma.
abstract: Systemic inflammatory responses to severe trauma and surgical illnesses may be partly responsible for numerous complications, including sepsis, multiple organ failure and unregulated hypermetabolism leading to protein-calorie malnutrition. The integrity of the gastrointestinal tract appears to be an important factor in the pathogenesis of the systemic inflammatory response and sepsis. Resuscitation and nutrition support strategies for preserving gut mucosal integrity have therefore been strongly promoted. This review summarizes the scientific rationale for emphasizing enteral nutritional support of surgical patients, discusses some important limitations of enteral feeding and argues for a flexible approach to nutrition support for these complex patients.
