Nutrition in Necrotizing Enterocolitis and Following Intestinal Resection

Area of Science:

• Neonatal nutrition
• Gastroenterology
• Surgical outcomes

Background:

• Necrotizing enterocolitis (NEC) is a significant concern in preterm infants.
• Nutritional and feeding strategies are critical for NEC prevention and management.
• Current medical treatments for NEC are limited, often necessitating surgical intervention.

Purpose of the Study:

• To review the role of nutrition and feeding practices in NEC.
• To discuss NEC prevention, complications, and surgical treatment.
• To highlight knowledge gaps and future research needs.

Main Methods:

• Comprehensive PubMed search focusing on meta-analyses and randomized controlled trials.
• Review of existing literature on nutrition, feeding practices, and NEC.
• Analysis of data related to intestinal adaptation and parenteral nutrition.

Main Results:

• Breast milk is the sole established method for NEC prevention.
• Late feeding initiation, slow advancement, and continuous feeds do not prevent NEC.
• Surgical resection leads to intestinal adaptation, with macronutrient effects studied in animal models.

Conclusions:

• Optimal feeding strategies for NEC prevention, especially in extremely preterm infants (<28 weeks, <1000g), require further research.
• Identifying biomarkers for intestinal recovery and individualizing feeding resumption post-NEC is needed.
• Understanding nutritional aspects of NEC and post-surgical adaptation remains a critical research area.
