Nutritional Considerations in Neonates Requiring Gastrointestinal Surgery.

Abstract

Neonates who require gastrointestinal surgery are a complex group of patients that require special consideration with regard to nutritional supplementation and growth. During the acute postoperative phase, a major stress response causes catabolism with degradation of the body's nutrient stores leading to poor growth. Following surgery, parenteral nutrition is often required to support the surgical neonate; although, enteral nutrition, if feasible, is critical because it helps improve intestinal adaptation. However, the best type, mode, and duration of feeding is not established in the current literature. It is important to factor in the individual patient anatomy and site of intestinal resection when considering intestinal absorptive ability because these patients are at high risk for nutrient malabsorption, with the risk persisting even when enteral autonomy is achieved. The neonate undergoing gastrointestinal surgery requires close growth and nutritional monitoring both during the neonatal period but also into later life because risks of abnormalities persist. In this review, we summarize the impact of gastrointestinal surgery and postoperative intestinal changes on infant growth and nutrition.
