Summary

Necrotizing enterocolitis (NE) is a severe gastrointestinal emergency in premature infants, causing significant morbidity and mortality. Its exact cause remains hypothetical despite identified risk factors like prematurity and feeding.

Area of Science:

Neonatal Medicine
Gastroenterology
Pediatric Surgery

Background:

Necrotizing enterocolitis (NE) is the most common gastrointestinal emergency in neonatal intensive care units.
This necrotic-inflammatory bowel disease primarily affects premature infants, contributing significantly to neonatal morbidity and mortality.
Identified risk factors include prematurity, enteral feeding, hypoxia, and microbial factors.

Purpose of the Study:

To review the current understanding of necrotizing enterocolitis (NE) in premature infants.
To discuss the multifactorial etiology and known risk factors associated with NE.
To highlight the hypothetical nature of the pathogenic sequence in NE.

Main Methods:

Literature review of necrotizing enterocolitis (NE).
Analysis of risk factors contributing to NE pathogenesis.
Synthesis of current knowledge on NE etiology.

Main Results:

Necrotizing enterocolitis (NE) is a leading cause of death and illness in premature newborns.
Key risk factors identified include prematurity, feeding practices, oxygen deprivation, and microbial influences.
The precise sequence of events leading to NE is not fully elucidated.

Conclusions:

Necrotizing enterocolitis (NE) remains a critical neonatal challenge with multifactorial origins.
Further research is needed to clarify the exact pathogenic mechanisms of NE.
Understanding NE etiology is crucial for improving outcomes in premature infants.
