This is a prospective study of 50 patients with neonatal necrotizing enterocolitis (NEC) treated successfully by medical means. They were all screened with an upper gastrointestinal (GI) contrast study after 14 days of healing and prior to establishment of feeding. Thirty-six patients (72%) with normal upper GI examinations responded well to a graduated increase in feeding. Another 5 (10%) with questionable areas on their upper GI examination had a normal follow-up contrast enema. Feeding was successfully established in this group of infants also. The remaining 9 patients (18%) had demonstrable strictures in both contrast studies. After elective resection of strictures with restoration of intestinal continuity, they were also fed successfully. No delayed strictures were seen in any of the patients. We propose that this method of evaluation is safe, efficient and reliable in the diagnosis of strictures that develop in patients recovering from NEC.

Breast milk is an essential source of infant nutrition. It is also a vital determinant of the structure and function of the infant intestinal microbial community, and it connects the mother and infant intestinal microbiota. Human milk oligosaccharides (HMOs) are a critical component in breast milk.

Purpose: To investigate the clinical features of necrotizing enterocolitis-associated intestinal perforation (NEC-IP) in neonates with different gestational ages (GAs). Furthermore, we also want to identify the risk factors of poor prognosis for these patients.
Methods: The retrospective study of patients with NEC-IP was conducted with basic information, comorbidity, intraoperative findings, related treatment, and prognosis.
WNT2B is Wnt ligand which is able to support intestinal stem cells (ISC) in culture and support the intestinal epithelium in vivo. We have previously shown that WNT2B is critical for resistance to colitis, but not small intestinal injury, in the adult mouse. WNT2B is thought to coordinate with WNT3 in supporting ISC, and we have also shown that WNT3 expression is low in the early postnatal ileum in mice.

Purpose: Necrotizing enterocolitis (NEC) majorly affects premature infants, causing not only necrosis and inflammation but also feeding intolerance and gastrointestinal dysmotility, hinting at gut hormone secretion impairment. Particularly critical is the gestation period before 26 weeks where intestinal hormonal activity is partially developed, rendering preterm neonates highly susceptible to NEC. Emerging evidence suggests a role of gut hormones, especially glucagon-like peptides (GLP) in ileum development.
